(54) DESIGN FOR PNEUMOTHESOL. - Drinks and chips

The invention relates to a machine tool industry, in particular, to devices for pneumatic suction of dust and chips from the cutting area of machine tools, such as metal-cutting. Devices for pneumatic suction of dust and chips from the cutting area of a cutting machine with a rotating tool, fixed in the spindle by means of a transition mandrel, containing an open part of the workpiece and permanently mounted on the mandrel with a gap, ensuring its rotation, hollow dust collector, and also connected to. the pneumatic suction system is movable from the case of water. The casing is made detachable consisting of two parts, which, after installing the tool together with the tool holder in the machine spindle, move in a plane perpendicular to the axis of the spindle and tightly enclose the dust tool tool in the outer diameter, providing the joint of the casing with the internal cavity, butt tool holder 1 Such devices are complex in design, since each part of the casing requires a separate drive and precise synchronization of their operation with the details of the drive unit and parts The burner clutters up the working area of the machine. This limits the possible ways to move the tool from the magazine to the spindle and back. In addition, it is often necessary to process the part located on the machine table at an angle to the axis of the axis. With this arrangement, the end face of the part can significantly deepen beyond the end face of the spindle. The presence of two parts detachable casing with drives eliminates the possibility of processing such parts. You can try to work out such a part without suction, scouting the parts of the casing, but one of these parts or their actuators can prevent the table with the part from being set to the desired position. Diluting the housing parts over long distances from the spindle will make the drive unit more difficult or even impossible due to the layout or dimensions of the machine. In order to release the working area of the machine by unilateral supply of the casing to the dust collector. One of the two parts of the casing is mounted on an axis, which can be rotated, carries the teller of another part of the casing and is kinematically connected with the drive of its movement. When docking, one part of the wheel cover covers the first and the other end surface of the diameter of the dust collector on the receiver, On the axis of rotation of the rotary shaft of the wheel, it is connected with the gear wheel, which is in engagement with the rail located in. direction, made in the other part of the casing with the possibility of displacement and contact with the end surface with the stop rigidly mounted on the casing drive.

FIG. 1 shows the machining area on a machine with a horizontal spindle and a table, top view; in fig. 2 shows section A-A in FIG. on an enlarged scale, rotated 180; in fig. 3 shows a section BB in FIG. 2; in fig. 4 - part machining area set under angle: ohm to the spindle axis.

On the test station 1 with a gap in the axial and radial directions, a dust collector 2 is installed, having a window 3 in outer diameter that connects to the inner cavity 4. The dust receiver 2 is connected to the suction pneumatic system of part 5 of the casing supplied from one side to dust collector. On the axis b of part 5 with the possibility of rotation, another part 7 of the casing is installed, rigidly connected to axis 6 by a pin 8. Axle 6 is held in part 5 of the casing with the help of patch plate 9, screwed to the part 5 of the casing with screws, Axis b a cog wheel 10 engaging with the rail 11 movably mounted in the guides 12 and 13 of the casing part 5. The rail 11, with its end face, is pressed against the stop 14, which is rigidly fixed on the lever 15 for the drive of the casing by an extension spring 16. Lastly, one end is fixed on pin 17, pressed into rail 11, and the other on rail 13. In rail 11, a limiting body 18 is mounted. In part 5 of the housing on axles 19, clamps 20 are installed in the form of two shoulders, the entrance with their front ends into the ring groove 21 of the pseudo-receiver and under the constant action of the compression spring 22. .

The front cover is in the retracted position of the spindle shown in FIG. 1 dash-dotted line. The rail 11, under the action of the spring 16, is pressed against the support 18 against the guide 13. Part 7 of the housing of the rail 11 11 is raised upward and takes up half the space shown in FIG. 2 in dash-dotted: line. ..

after turning on the casing grip, its lever 15 rotates clockwise (Fig. 1) and moves the casing part 5 to: a dust-collecting tool. The stop 14 comes into contact with the end face 1m of the rail 11 and moves it in the guides 12 and 13. The rail 11 rotates the gear wheel 10 and the axis 6 with fixed to

In this case, part 7 of the casing, which comes close to the interface of the piston receiver 2. As this approaches, the grippers 20 first come into contact with the piston receiver 2. The front ends of the grippers 20 fall into the groove 21, disperse, compressing the spring 22, and then fix the dust collector 20. 1 with gaps. E axial and radial directions. At the time of the docking of the part 5 of the casing with the dust-collecting receptacle from the casing supply side, part 7 of the casing covers the dust-collecting receptacle on the other side.

Thus, the reciprocating receiver 2 is covered over the entire outer diameter and connected to a pneumatic outlet system. After the docking is completed, the spindle can be turned on.

Stripping occurs in the reverse after the spindle stops.

Using a detachable casing known devices (Fig. 4) impossible processing of parts located on the table 23 of the machine at an angle to the axis of the drive. The butt end 24 of the workpiece is significantly deepened beyond the end 25 of the edge. The body of the part incorporates the meito needed to open one of the parts of the split housing with the drive.
