Abstract

The invention relates to devices for centering and securing parts for machining onto lathes and other machines. The disclosed chuck comprises a body having gripping jaws with oblique operating surfaces, and a device for resetting said jaws. The chuck further comprises cuneiform bars and a device for moving them, said device having nuts with right and left threads and a lead screw mounted in the body so as to permit its axial rotation. The chuck is further equipped with a clamp to guide the lead screw. The device for resetting the jaws has a maximum of two stops, which may be two pivoting stops with an excentric end protrusion. The common operating element for the jaws is formed from articulated sections of two cylindrical cogged wheels which operate in conjunction with an oblique, rack-type cog on the cuneiform bars.

Low productivity of cam adjustment due to the need to press the sensitive button each fist, which involves pumping the pathon with each fist onto the pump. Another drawback is the complexity of the design of the safety buttons, which contain several parts and springs; for safety reasons, it is also necessary to have a signal finger in the cartridge indicating the disengaged position of the cams. The described chucks do not allow quick readjustment of the cams, since the movement to an additional path for disengaging the cams occurs through the cam screw, which requires several key turns and a lot of time.

USSR No. 810390, MKII: B 23 B 31/16, published on 07.03.1981), which allows for centering and fastening of parts of complex configuration. However, the design of the chuck does not allow the use of more rigid and lighter in weight (important due to the action of centrifugal forces) solid jaws, since the possibility of quick reinstallation to different ranges of sizes of clamped parts is not provided for them. The disadvantage of these cartridges is also low productivity and inconvenience in operation, especially when clamping parts of simple, straight (angular, square) configuration. This is due to the fact that the operator moves the jaws to full working position when releasing the part. Regardless of whether there is a need for this. The closest in technical essence to the claimed first variant of the invention is the four-jaw wedge-type self-centering chuck with a manual drive key (Self-centering chuck (assembly drawing) selected as a prototype type) Phima 'ΥΑΤΕ-ΡegеΙ Μесаηϊсδ Ys, (Public Guzia), mod. 4Η200 - type of the first variant), (Four-fist self-centering patent with a fatty acid, phim "νΑΤΕ-ΡерГесΙ Μесаηϊсδ ьϊсΙ", (Public of Guzia), from the series "4H".

It allows for centering and fastening of parts of complex configurations, and also for using solid jaws. The chuck contains a cap with radial guides, two pairs of jaws with differently inclined teeth and a device for their reset, two pairs of wedge rods with journals and clamps, movable tangentially in relation to the center of the chuck to the working and additional (for disengaging the cams during their readjustment) stroke. The drive device includes two central and with the possibility of turning drive rings installed in the casing, two nuts with right and left threads, placed with the possibility of contact between themselves and with a lead screw with differently directed threaded parts. The propeller is installed in the housing with the possibility of rotary motion and axial displacement. A three-jaw self-centering chuck with a mechanized drive is known (Three-jaw chuck with a mechanized drive, mod. "KRE", company "KOR" (FRG). Advertising perspective). Its disadvantage is the impossibility of centering parts of complex configuration (for example, square, rectangle, eccentric, oval) and low productivity when fastening such, since special attachments to the cams are needed. Another disadvantage of this cartridge is the impossibility of using more rigid and lighter (the latter is important due to the action of centrifugal forces during cartridge rotation) solid cams. The design of the described chuck does not allow for the quick adjustment of solid jaws to different ranges of sizes of clamped parts.

This occurs as a result of the fact that the process occurs when you release the part, wash the cams on a full workday regardless of whether there is a need for it. This is caused by the fact that the cams move in pairs and from the part, first one pair of cams begins to move, the one with less natural resistance to friction forces in the kinematic chain, and the other pair begins to move only after that, as the first one selects the full working stroke and the drive wedge paths are tightened into the casing. This also causes each time the disengagement of the wedge path of the rack and pinion transmission and the release of the cams of this pair, again regardless of necessity. Well, there is, the therapist does not have the opportunity to move his fists on the right key as much as he needs, It moves it throughout the entire passage, including the empty one. Regarding the design of the described path, there is also no protection against cam flight (the requirement safety conditions) if the operator did not notice the freed cam and turned on the machine.

The disadvantage of this type of version of the claimed invention is the insufficient speed of changeability of the cams, why is it necessary to pump the patina with each fist on the pump to unfasten each and every one. Another disadvantage is the impossibility of using more rigid, solid and lightweight (as long as they can be made narrow by design) cams, since the possibility of reinstalling (reversing or replacing) such cams is not provided for. different diameters of the clamping surfaces, due to which the maximum permissible value of the cartridge rotation frequency is limited. The disadvantage of this type is also the extreme technological complexity of making precision screw grooves with a larger lift angle on a common drive ring and different screw guides on the wedge guides.

Secondly, prefabricated jaws, consisting of a base jaw and a clamping jaw fastened to it with screws and clamps, have more mass than solid jaws, since the latter designs can be made narrow.

This is achieved by the fact that the lead screw is fixed from axial displacement. And in the case of fastening parts of a complex configuration, when a parallel movement of the cams is required, the operator has the ability, by pressing the clamp and thereby releasing the lead screw from axial fixation, to transfer the chuck to the corresponding operating mode. Moreover, due to the presence in the chuck of the proposed invention of only one drive movable (rotatable) control for all wedge paths, for the rapid release of all or any of the cams separately from engagement when they During pre-adjustment, it is sufficient to operate the key only on one full-fledged down) and only with one side of the press, turning it only 180° and back. These technical results provide for an increase in productivity and an improvement in the ease of use of the proposed four-jaw wedge-type chuck, while maintaining the functional capabilities of the latter in centering and clamping parts. complex configuration, using lightweight cams (i.e. maintaining a high value of permissible rotation frequency of the camshaft) and maintaining safety conditions.

Those need to be reinstalled. The installation of a stopper, which limits the axial displacement with a spindle, allows the operator to move the jaws when clamping round and square-shaped parts (which are the most common in the range of workpieces) when releasing parts within the working range as much as necessary, but not necessarily the entire length. This allows for increased productivity. The installation of only one seal, limiting the working stroke of all wedge rods and also intended for their rapid movement to an additional stroke, for reinstallation, reversal or replacement of cams, eliminates the need for turning Press each fist towards each other for restarting. The need for the presence in the design of the chuck of safety fingers with buttons at each cam, designed to ensure safety in the event that the operator does not notice the disengaged cam and turns on the machine (spindle rotation), is also eliminated. The need for a signal (indicator) finger to warn the operator of this position of the cams is also eliminated. Safety is ensured by the fact that the operator, without inserting the cams back into engagement, will not be able to pull the drive key out of the chuck and, accordingly, will not turn on the chuck rotation together with the key. But if you use any other key (without a locking groove) and turn the camshaft adjuster, it simply won’t be able to. Thus, the design of the camshaft is simpler and ensures compliance with safety conditions.

Acting on one rotary control. The operator decouples and can reset two cams at once. The design of the cartridge allows the use of solid cams, which are lighter in weight (the design is narrower), since the possibility of their quick reset is provided, due to the smaller magnitude of the centrifugal forces that arise during the rotation of the cartridge. The design of the common drive ring with oppositely directed screw grooves in the form of double-jointed cylindrical wheels with oppositely directed inclined inclined teeth removes the technological difficulties of their manufacture, since they can be manufactured with high precision traditional dental processing

There is the following cause-and-effect relationship between the distinctive features and the technical result: due to the presence in the cam reset device of only two-speed gears, which ensure rapid disengagement of all four cams, the operator has the possibility of influencing the pathon only from one side, without pushing it with each fist towards you. The implementation of the general drive element from articulated sections of two, a traditional design, gear wheels interacting with rack teeth, simplifies the design, increases the accuracy and efficiency of the pattern (the latter as a concomitant effect).

When the cams of one pair, say 3, reach the centered part first, they and the wedge rods 7 and wheel 1 1 connected to them stop their movements. The reader must then press the fixator with his finger, i.e. plunger 23, removing protrusion 26 from engagement with groove 21 and thereby releasing lead screw 15. In this case, hole 25 of plunger 23 simply fits into neck 22 of lead screw 15, without interfering with the possibility of axial displacement of the latter. Further rotation of screw 15 from key 20 leads to the displacement of only the pair of cams 4 due to the differential transmission of motion by means of slider 18, drive wheel 12, rods 8 and the displacement of lead screw 15 along its own axis in the direction of 19. Moreover, the movement of cams 4 after the stop of cams 3 occurs according to the differential principle two times faster than with simultaneous movement due to unscrewing of threaded part 14 of lead screw 15 from nut part 13 of stopped rod 7. In this way, the workpiece is centered and secured in two mutually perpendicular directions. Moreover, parts of practically any configuration can be fastened, and parts of the shape with symmetrical dimensions from the center in two mutually perpendicular directions to the intersection with the lines describing the shape of the part can be centered and fastened.

The resetting of the cams along the teeth is carried out in the following manner: Sequences. The cams move back by turning screw 15, i.e. About Paton's cent, in the last position and the working process. The extreme rear position of the working stroke of the wedge rods is limited by the fit of the edge 32 of the groove 33 of the rod 7 in the jaw 30 of the fitting 27. This is for the clamping jaws 3, and with the other side by pressing the edge 34 of the groove 35 into the cam 31 of the fitting 27 - this is for the other pair of clamping cams 4. After this, the special key 29 is inserted into the hole 28 of the fitting 27, which is in the initial angular position. Ball 37 is then partially pressed into the recess on the cap and does not interfere with the insertion of key 29. In another angular position of finger 27, it is impossible to insert the key into square hole 28, or to remove it from it, or to insert another key (without groove 38).

The cam 31 begins to enter the groove 35 of the slider 18 and move it into the groove 6 and simultaneously, through the lead screw 15, the wedge rod 7 moves in the same direction. Both gear wheels 1 1 and 12 at this time rotate in the same direction and as a result, wedge rods 7 and 8 move clamping jaws 3 toward the center of the cartridge, and jaws 4 away from the center of the cartridge. At this point, the teeth 9 of the wedge lugs 8, moving to an additional distance, disengage with the teeth 5 of the cams 4. Thus Thus, cams 4 will seem to be free from engagement and they can be reset (changed or replaced with other ones) to the desired position number of teeth 5. After this, key 29 is turned back to its original position, thereby bringing racks 8 back into engagement with cams 4. After this, if there is no need to reset cams 3, the key can be removed from hole 28. And if necessary Reinstallation of cams 3 is also necessary, the key is turned 180° in front of the hour insignia. Then cam 30 comes into interaction with groove 36 on slider 18 and moves it, using screw 15, wedge Steps 7 for an additional step and cams 3 and 4. At this point, cams 3 will move at the same level as the cams 4 - to the center. In this way, the engagement of cams 3 is released for reinstallation. Then 27 is returned to the original working position, which is similar to the above, wedge wedges 7 are introduced Moreover, it is engaged with cams 3. If the sealant does not return 27 to its original position (which means safe, i.e. engaged position clamping jaws), then he will not be able to get key 29 from socket 28.

The workpiece being processed, say of round or square shape, is installed in cams 42 and 43. From the machine drive (not indicated in the drawings), the rod 50 and the wheels 51 and 52 mounted on it are moved. The beveled teeth 53 and 54, interacting with the beveled rack with teeth 49, according to the principle of wedge feed, we move the wedge points 46 and 47 in a tangential relationship about the price of Paton and in the opposite direction. The wedge rods 46 and 47 interact with the inclined rack teeth 48 with the inclined rack teeth 44 and, according to the principle of wedge transmission, move the cams 42 and 43 in the guides 41 of the hood 40 either to the center of the chuck or from the center, depending on that. The workpiece is clamped from the outside or from the inside. This ensures that the workpiece is centered and secured. The clamping force is maintained by the machine's continuously operating drive.

Pairs of cams 42 and 43 move in the direction of the fastened part in the same way as described above. When the cams of one pair, say 2, reach the centered part first, they and the wedge rods 46 connected to them stop their movements. Helical gears 51 and 52, which are engaged with rack teeth 49, continue their driving movement along the axis of the groove after the wedge rods 46 stop, and begin to rotate on the central rod 50 and, acting according to the “wheel-rack” principle, move wedge rods 47. In this case, according to the differential principle (since wedge rods 46 have stopped), rods 47 and the pair of cams 43 associated with them move at an accelerated stroke due to the unscrewing of teeth 53 from the beveled rack teeth 49 of the stopped rods 46.

Moreover, parts of practically any configuration can be fastened, and parts of the shape with symmetrical dimensions from the center in two mutually perpendicular directions to the intersection with the lines describing the shape of the part can be centered and fastened. To fasten parts of different sizes (when the working stroke of the cams is insufficient), cams 42 and 43 are reset to the appropriate size by resetting to the required number of steps (depending on the shape of the part) along the rack teeth 44. Resetting The cams and teeth occur in the following sequence. The cams follow the action of the machine's feed (by moving the rod 50 per step, i.e., to the front foot of the machine) moves back, i.e. About Paton's cent. In this case, the edges 58 of the grooves 59, made on one of each pair of wedge rods 46 and 47, are fitted into the projections 57 of the turning seals 55 and 56. After this, the special key 61 is inserted into the socket 60 of the seal 55 and rotated 180°. When turning the adjustment 55 by 180° by means of the interaction of the eccentric projection 57 with the groove 59 of the wedge rod 46 and the same rod 46 (from the same pair) through the helical gear 51, also the wedge rods 47, through the gear 52, move in one direction (tangentially in relation to the point of the index on the hour handle) for an additional χοd. In this case, the inclined teeth 48 of the rods 46 will disengage from the teeth 44 of the cams 42, and the latter can be reset to the required number of teeth 44. The special key 61 is turned back by 180°, which leads to the reverse input into the working engagement of the cams 42. Only after this (for safety reasons) can the operator remove the key 61 with the groove 63 from the socket 60 with the locking ball 62.

This is due to the fact that the lead screw is fixed from the axial displacement. And in the case of fastening parts of a complex configuration, when a parallel movement of the cams is required, the operator has the ability to press Fixing and, thereby, releasing the right screw for sowing fixation, bringing the soil into the appropriate mode work. And thus, for the quick release of all or any of the cams on the engagement of the piston and the reinstallation it is enough to operate the key only for one day, turning it only 180° and with One only There's no need to push Paton with every fist on the pathologist. These technical features lead to increased productivity and ease of use of the four cams Paton, and this combines the functional capabilities of the latter for centering and clamping complex parts Configuration, name of lungs (narrow) cams and thereby maintaining a high value of the permissible frequency of rotation of the camshaft while observing safety conditions. The proposed essence of the second variant of the claimed invention can be used in many ways in the field of machinery, and more specifically in machine tools with the receipt of a technological result consisting in the fact that the disengagement of all four cams (and during pre-commissioning) it uses only two angles and only 180° and so on placed on one side, enriched with patophone. The patent design allows you to use light (narrow) fists. The implementation of the general drive element in the form of articulated gear wheels simplifies the design, since it is subject to the possibility of manufacturing on traditional technological equipment. These technical results result in increased productivity, operational properties and simplified design. At the same time, the functional capabilities of the chuck for centering and clamping parts of complex configurations, using light clamping jaws and thereby maintaining a high value of the permissible rotation frequency are preserved, and safety conditions are observed.
