Definitions

  • the hand machine tool can be used wherever work and machining is carried out using tools of all kinds.
  • the area of manual workmanship by non-specialists should be taken into account, as well as the area of professional handicraft and industrial processing.
  • the invention relates to a hand machine tool according to the preamble of claim 1, in particular for drilling, punching, sawing, chiseling, filing, grinding, screwing, drilling saws, rasps, drilling files, circular saws, rasps, planing with a working shaft and with a, preferably electric, drive motor.
  • a generic hand machine tool is known from WO-A-89/11955.
  • Such machines are for certain functions, e.g. known as a saw-file rasp or as a drilling and impact drilling machine.
  • a machine tool for stone processing in which the striking tool can be set either in a striking movement or in a striking and at the same time rotating (drilling) movement (DE-U-19 03 434).
  • a rotary hammer has also been proposed in which an automatic switchover to the most varied of operating modes is possible, the technical solution being that a contour is scanned on the tool used is and the resulting information is converted into switching signals, for example for a certain speed and for a certain number of strokes (DE-A-37 20 512).
  • a hand-held tool in which a tool can be set either into a rotation or into a rotation and a striking movement or into a pure striking movement, the special solution being that there is a very specific association between the speed and the striking movements, to make holes in a perforated base in a very specific way (EP-A-143 086).
  • a very special embodiment shows an externally driven saw, the special idea being to use a drill known per se as the drive, which is connected to the actual saw via a flexible shaft. The rotary movement is then set into a translational movement in the housing of the saw (US Pat. No. 4,841,643).
  • Another known drill shows a gear design with which the number of blows per revolution of the output shaft can be adapted to the material of a workpiece to be machined when the speed of the output shaft is set.
  • the proposed option for this consists in a gear on the output shaft which can be displaced on a spline, which can be assigned to different pinions of the drive (DE-C-27 34 965).
  • a generic machine tool with a working shaft provided with a tool holder and a drive device in which the rotary movement continuously transmitted from a drive motor to a tool holder can be switched off and locked as desired, a rotatable intermediate shaft, which is axially displaceable and has a toothing in which one or the other axially different position can be brought with an externally operable switching device such that the toothing either for switching the rotary movement on or off or for non-rotatably locking the working shaft of a tool - Or disengageable, the working shaft of the tool can, if required, be simultaneously set in a reciprocating movement with a swash plate gear which can be driven via a clutch which can be switched by axial displacement of the intermediate shaft.
  • the invention has for its object to provide a hand machine tool of the generic type for a larger number of different machining functions, in particular for drilling, filing, rasps, drilling files, circular saws, grinding, planing, impact drilling, screws, saws, saws, rasps and chisels. Furthermore, it should, preferably possible when the work shaft is at a standstill, another work machine, e.g. to drive a circular saw.
  • Another tool e.g. a circular saw or a flexible shaft, connectable. It is advantageous if the sixth clutch is arranged on the side of the drive motor facing away from the tool holder on the working shaft.
  • a coupling of the first and a coupling of the second group can be made separately selectable, enables a number of different functions to be achieved. If the shaft is rotated via the first clutch, a round rasp can be set in rotating and simultaneously reciprocating motion when the third clutch engages, or hammer drilling can be carried out when the fourth clutch engages, or it can be done when the fifth clutch engages Coupling the working shaft must be locked in the longitudinal direction and so normal drilling or screwing can be carried out.
  • a sawing movement can be achieved via the third coupling or a striking movement for a chisel via the fourth coupling or complete locking via the fifth coupling, so that the machine tool as a whole can be used like a screwdriver with increased leverage.
  • the machine tool can also form the drive for another machine tool as a motor.
  • the embodiment of the hand machine tool according to the invention is characterized in that the motor rotates a first bevel gear with an axis parallel to the working shaft, which drives a second bevel gear with an axis approximately perpendicular to the working shaft and that a push rod gear for generating the oscillating movement parallel to the working shaft, and that a third bevel gear with an axis parallel to the working shaft is axially displaceable such that it either engages with the second bevel gear in the form of the first clutch or is locked in the form of the second clutch, whereby a fixedly connected to the third bevel gear first spur gear is in engagement with a second spur gear attached to the working shaft and that the working shaft is mounted displaceably in the axial direction and that on the working shaft one over a certain, such as the stroke of the oscillation corresponding movement distance, e.g.
  • an inner stop on the the drive, e.g. a drill chuck, side facing away
  • an adjustable, e.g. ring-shaped, external stop arranged on the working shaft is arranged in the axial direction on the working shaft freely movable block to which the oscillating movement is fed with a certain stroke and that the block is held in a first position of the outer stop, for example clamping, in such a way that the working shaft follows the oscillating movement supplied to the block in the axial direction or that the outer stop is in a second position which is less than the stroke of the oscillating movement and is less than the stroke of the oscillating movement Position is fixed so that with each movement an (outward) blow is applied to the working shaft, or that the outer blow is arranged in a third position which is more than the stroke of the oscillating movement away from the first position, so that the working wave from the oscillating motion ni is not influenced and stands still in the axial direction.
  • the oscillating movement is thus produced by means of a bevel gear, which at the same time serves to transmit the rotary movement or to lock the working shaft.
  • the movement in the longitudinal direction can be adjusted in a simple manner by means of the adjustable outer stop, which then acts like separate (third, fourth, fifth) couplings.
  • the block can be freely rotated on the working shaft so that it can rotate with the oscillating drive can be connected.
  • the working shaft is expediently returned to a certain rest position by means of a tension or compression spring on an adjustable carriage, so that an adjustment of the outer stop is possible without difficulty and the required distance for the block remains free during the oscillating movement.
  • a working shaft 1 carries a tool holder 2, e.g. a drill chuck.
  • the shaft 1 is supported in bearings 3 and 4 in such a way that it is longitudinally extended by a stroke of e.g. 15 mm is displaceable.
  • a drive shaft 6 can be set in rotation by a motor 5.
  • a first and a second clutch 11 and 12 Arranged on the shaft 6 are a first and a second clutch 11 and 12, which can set or block the working shaft 1 in rotary motion via transmission members 21 and 22 and a gear arrangement 7.
  • the third clutch 13, the fourth clutch 14 and the fifth clutch 15 are also arranged on the shaft 6 and are connected to the working shaft 1 via transmission elements 23, 24, 25 and gear arrangements 8, 9, 10.
  • An oscillating movement or a striking movement can be supplied in the longitudinal direction by means of the third coupling 13 or via the fourth coupling 14 of the working shaft 1.
  • the working shaft 1 can also be locked by means of the fifth clutch 15.
  • the working shaft 1 rotates, but cannot be moved in the longitudinal direction.
  • the effect of a drilling machine is thus obtained.
  • the clutch 13 is closed, the working shaft 1 reciprocates in the longitudinal direction and rotates in the process; it can thus be used in the chuck 2, for example, a round rasp with which openings in a wooden plate can be created and enlarged.
  • the clutches 12 and 13 closed, the working shaft 1 does not rotate, but moves back and forth in the longitudinal direction. A normal saw blade can thus be brought into effect in the tool holder 2.
  • the clutches 12 and 14 are closed, the shaft does not rotate, does not move appreciably in the longitudinal direction, but only exerts impacts.
  • a chisel attached to a tool holder 2 can thus do its job.
  • the shaft 1 rotates and strikes; a hammer drill can therefore be brought into effect.
  • the clutches 12 and 15 are closed, the working shaft 1 is immovably fixed.
  • a tool inserted into the holder 2 can thus be used in the intended manner, the hand machine tool as a whole being able to be used as a larger handle with increased force and leverage.
  • screws also Allen screws or screws, can be actuated by hand using a socket wrench, whereby after overcoming a greater resistance, the rotary movement can be started by switching from 12 to 11, thus further loosening the screw in question can be effected.
  • a sixth coupling 16 to drive another tool, for example a circular saw, flexible shaft or the like.
  • another tool for example a circular saw, flexible shaft or the like.
  • the hand-held machine tool is also used as such, and its motor and the control circuits for speed and force, which are provided in a manner known per se can be operated together.
  • the working shaft 1 in the bearings 3 and 4 carries a drill chuck 2 or another tool holder.
  • a second bevel gear 33 in engagement with the first bevel gear 31 is mounted on an axis 32, indicated only by dashed lines and perpendicular to the working shaft 1.
  • the axis 32 is fixed in a bearing block 34.
  • a third bevel gear 35 with an axis 36 is arranged on a bearing block 37.
  • a spring-loaded pin 73 which engages with a corresponding axial displacement of the spur gear 38 in a bore 74, not shown, in the gear 38 and fixes it.
  • the third bevel gear 35 is structurally connected to a first spur gear 38 which is in engagement with a second spur gear 39 on the working shaft 1.
  • the second spur gear 39 has a considerable length such that the shaft 1 can be displaced in the longitudinal direction in accordance with the intended stroke, without the rotation of the working shaft 1 being impaired.
  • the shaft 1 is on the far right and touches with the flank of the spur gear 39 the bearing block 4, which is optionally provided with a slide bearing or also with a ball bearing 40 on the end face.
  • an adjustable fixed stop ring 41 is attached, with which, as will be described later, the oscillating movement can be adapted if necessary.
  • An axle bearing 42 which is connected to a push rod 43, is eccentrically attached to the second bevel gear 33.
  • This push rod which can optionally be divided and additionally supported, actuates a movement rod 44.
  • the other end is fastened to a block 45 which is moved back and forth on the axis 1 in the longitudinal direction in accordance with the stroke represented by a double arrow 51 when the bevel gear 33 rotates in a circle.
  • a driver 46 is attached to the working shaft 1, which can snap into a first, second or third groove 47, 48 or 49 in a manner shown in more detail in FIG. 3, wherein it has an adjustable outer stop for the movement of the block 45 the shaft 1 forms.
  • the driver 46 If the driver 46 is engaged in the groove 47 shown on the right, it practically rests with its lateral surface on the side surface of the block 45; the side surfaces of which can carry damping elements and / or ball bearings 50 in order to prevent mechanical interference during the reciprocating movement of the block 45 and during the rotation of parts attached to the shaft To avoid stress.
  • the block 45 In this position, the block 45 is thus enclosed between the stop 41 and the driver 46; during the lateral movement of the block 45, the shaft 1 is thus taken along with the parts attached to it and carries out the oscillating movement predetermined by the bevel gear 33 from the eccentric arrangement, which is transmitted via the movement rod 44 from the push rod 43 to the block 45.
  • This setting is therefore suitable, for example, to put either a fixed saw or a rotating circular rasp into operation, depending on whether or not a rotary movement is transmitted to the second spur gear 39 from the first spur gear 38.
  • a tension spring 52 can be arranged over the end of the shaft so that it pulls the shaft 1 into the position shown in the drawing, in which the second spur gear 39 is pulled against the bearing 4. If the spur gear 39 is now supplied with rotation, the machine tool according to the invention can work as a drilling machine.
  • the block 45 can initially move freely over approximately half of the stroke 51 and does not move the shaft 1. Then the block 45 hits the Carrier 46 and moves it forward a little. In this way, a blow can be exerted on the tool mounted in the tool holder 2, for example a simple chisel or a stone drill, which can then also be rotated.
  • a housing holding the parts together with a holder 53b in the manner of a drill handle is shown in a manner known per se.
  • this housing can also be provided with an additional handle 53c in the region of the bearing 3 in order to facilitate guiding the tool at work.

  • the swivel 78 is supported on a screw connection 78b at one end of a tension spring 52, so that an axial movement of the working shaft 1 is only possible under the influence of the spring force of the tension spring 52.
  • the tension spring is connected at its other end to an adjusting slide 55 which is adjustable via an adjusting clamping screw 55a.
  • Fig. 3 shows a hand machine tool according to the invention cut approximately along the line B-B in Fig. 2 in the view from above.
