Definitions

  • the invention is based on an electric hand tool, in particular an angle grinder, of the type defined in the preamble of claim 1.
  • Hand tools in particular angle grinders, of the type mentioned at the beginning are exclusively equipped with an on and off switch which is actuated via the switch strip.
  • the switch strip is located on the underside of the handle and is actuated by at least one finger when the handle is grasped and kept actuated while working with the machine.
  • the ergonomic design of the handle such as cross-sectional shape and angle of inclination to the device axis, is optimized for a single working position of the machine.
  • the same applies to the arrangement of the switch strip which is often equipped with a switch-on lock and switch-on lock, which can be operated quickly and safely in this working position.
  • a hand tool is known from EP 0 267 472, the handle of which, together with the switch strip, can be rotated about its longitudinal axis with respect to the motor housing. A lock for the handle is not provided. This solution is therefore unsuitable for hand-held power tools in which a torque is to be transmitted to the tool or the hand of the operator via the handle.
  • An angle grinder for example, is used in addition to grinding or scrubbing for cutting work, such as cutting stone slabs.
  • the optimum working position mentioned above is usually given for the scrubbing working position, in which the grinding wheel points downwards, that is to say is approximately parallel to the switch strip.
  • the angle grinder is rotated 90 o around its longitudinal axis to the left or right so that the cutting disc is approximately perpendicular to the workpiece. This rotation puts the handle and the switch bar in an unfavorable position for the comprehensive hand. If the machine is turned to the left and the handle is gripped with the right hand, the switch bar comes to rest in the ball of the hand.
  • the switch bar can only be held and operated with the thumb. In both cases, the switch strip cannot be held securely and without fatigue. In addition, in the event of danger, the position of the switch-on lock and switch-on interlock cannot be reacted to and switched off quickly enough.
  • the gear head with a tool holder for the grinding and cutting disc is detachably arranged on the motor housing in a known angle grinding machine. After loosening four fastening screws and removing them from the holes, the gear head on the motor housing centering can be turned 90 o to the right or left. After that they are Reinstall the screws and screw the gear head onto the motor housing.
  • the disassembly and reassembly of the gear head on the motor housing is relatively complex, so that this known angle grinder is not suitable for applications in which adjustments often have to be made.
  • the electric hand machine tool according to the invention in particular an angle grinder, with the features of claim 1 has the advantage of simple and quick handling.
  • the handle or gear head on the motor housing can be turned until the tool holder and switch strip are assigned to the new working position of the machine.
  • the locking device is activated again and the clamping device is actuated.
  • Locking and clamping devices ensure optimal safety for the operator, since on the one hand a relative rotation of the handle or gear head to the motor housing is reliably excluded and on the other hand there is a fixed connection between the parts that can move with respect to one another. Both devices are structurally simple and space-saving to implement and insensitive to dirt and dust.
  • the clamping device is particularly expedient realized in that the handle or gear head has a shell-like housing which engages with a radially projecting collar in a circumferential groove on the motor housing and has a longitudinal slot in the collar area, and in that the clamping device has a clamping screw extending transversely to the longitudinal slot, which by means of a clamping lever in a thread can be screwed so that the housing areas formed on both sides of the slot can be moved towards one another while reducing the width of the longitudinal slot.
  • the collar is clamped radially in the circumferential groove of the motor housing.
  • Providing a tooth coupling between the clamping screw and the clamping lever in the locking device according to a further embodiment of the invention which can be released by axial displacement of a coupling part, makes it possible to readjust the clamping force of the clamping screw and ensures that the clamping lever always assumes a precisely defined end position in its clamping position.
  • the locking device is expediently realized in that in the motor housing a number of locking grooves corresponding to the number of required working positions of the machine are provided, which are offset by corresponding angles of rotation, and in that a locking cam is pivotally arranged in the shell housing, which is form-fitting can intervene in one of the locking grooves.
  • an inevitable coupling of the locking and clamping device is achieved in that the locking cam sits in a rotationally fixed manner on a coupling sleeve which coaxially surrounds the clamping screw and which, in turn, also one of the coupling parts of the tooth coupling is operatively connected via a claw coupling.
  • a contact element of an interrupter contact is arranged in the locking grooves on the one hand and on the locking cam of the locking device on the other hand, which contact element is located in the electrical connecting line between the on / off switch actuated by the switch strip and the electric drive motor and is designed in such a way that that it is only closed when the locking cam engages in the locking groove. This ensures that the circuit to the electric drive motor is interrupted when the handle or gear head is adjusted and is only restored after proper locking and tensioning.
  • the side view of the electrical angle grinder shown in FIG. 1 as an exemplary embodiment of a general electric hand-held power tool has a motor housing 10 which accommodates an electric drive motor (not shown), a gear head 11 on one end of the housing and a handle 12 on the other end of the housing.
  • a tool holder 13 can be seen, in which here a grinding wheel 14 is held, which is used in the extended position for scrubbing and in a broken line position rotated by 90 ° for separation.
  • the handle 12 consists of a handle 15, which is enclosed by the hand when working with the angle grinder, and of a bracket 16 attached to it in one piece, which covers the handle 15 on the underside while leaving a through opening 17 and when working with the angle grinder around the handle handle 15 placed down protective covers.
  • a switch strip 18 projects into the passage opening 17, which actuates an on and off switch for the electric drive motor.
  • the gear head 11 is fixed to the motor housing 10, preferably in one piece, while the handle 12 is rotated relative to the motor housing 10 and can be fixed in certain rotational positions on the motor housing 10 by means of a locking and clamping device, both of which are actuated by a tensioning lever 19 .
  • the handle 12 has a shell-like housing, hereinafter referred to as the shell housing 20, which engages with a radially projecting collar 21 in a circumferential groove 22 on the motor housing 10 for the rotatable mounting of the handle 12 on the motor housing 10.
  • the shell housing 20 has a longitudinal slot 23 (FIG. 3), which enables the collar 21 to be clamped radially at the base of the circumferential groove 22 by means of the clamping device 24.
  • the shell housing 20 is made of two half-shells which are held together by three screw connections 25.
  • the two half-shells 201 and 202 and one of the screw connections 25 can be seen in FIG. 3.
  • the longitudinal slot 23 is on the top of the Shell housing 20 is formed at the joint of the two half-shells 201, 202.
  • the clamping device 24 consists of a clamping screw 26 which extends directly below the longitudinal slot 23 transversely to the housing axis and passes through a bore 27 in one half-shell 201 and can be screwed into a threaded hole 28 provided in the other half-shell 202.
  • the tensioning screw 26 is actuated by the tensioning lever 19, as will be explained in more detail below.
  • the tensioning lever 19 At the end of the clamping screw 26 facing away from the threaded hole 28, the latter is firmly connected to a first coupling part 31 of a tooth coupling 30, which is supported via a coupling sleeve 29 against a wall region surrounding the bore 27, which is formed by an external depression 33 in the half-shell 201 .
  • the first coupling part 31 carries, on a section tapered in diameter, a ring gear with radially projecting coupling teeth 34, into which similar coupling teeth 34 of a ring gear engage on the second coupling part 32, which coaxially encompasses the first coupling part 31.
  • the second coupling part 32 is formed in one piece with the tensioning lever 19, which projects at a right angle from the second coupling part 32 and extends laterally on the shell housing 20.
  • a bolt 35 is screwed in at the end, which carries a collar 36.
  • a compression spring 38 is supported between the collar 36 and an annular web 37 in the interior of the hollow cylindrical coupling part 32.
  • the block length of the compression spring 38 and the axial length of the clutch teeth 34 are coordinated so that the second clutch part 32 can be axially displaced by pulling the tensioning lever 19 away from the shell housing 20 to such an extent that the clutch teeth 34 are disengaged from the first and second clutch parts 31, 32 are.
  • the locking device 40 allows the determination of the handle 12 in three different rotational positions of the motor housing 10, in a in Fig. 1 - basic position shown 3 and in two 90 o offset rotational positions by rotating the handle 12 about the housing longitudinal axis from the starting position can be adjusted to the left or right.
  • the motor housing 10 carries three housing pegs 41-43 which are offset by 90 ° from one another and which project radially into the interior and each carry a locking groove 44-46.
  • An arcuate web 52 connects the three locking pins 41-43 to each other, each of which is attached to the free end of the housing pins 41-43 and is integral with them.
  • a locking cam 47 interacts with the locking grooves 44 - 46 and can be pivoted into the locking grooves 44 - 46 in a form-fitting manner in order to fix the handle 12 on the motor housing 10.
  • the bolt-shaped locking cam 47 is seated in a rotationally fixed manner on the coupling sleeve 29, which is part of the locking device 40.
  • the coupling sleeve 29 is rotatably seated on the clamping screw 26 of the clamping device 24 and carries on an annular web 39 comprising the first coupling part 31 of the tooth coupling 30, claws 48 of a claw coupling 50, which interact with corresponding claws 48 on the end face of the second coupling part 32 of the tooth coupling 30.
  • the claws 48 on the coupling sleeve 29 and on the second coupling part 32 are designed such that when the second coupling part 32 is axially displaced in order to release the tooth coupling 30, the claws 48 remain in engagement with one another, so that the claw coupling 50 is not released in the process.
  • the handle 12 is to be turned so that the locking cam 47 is aligned with one of the locking grooves 44-46. Then the clamping lever 19 from the in Fig. 2nd dashed line position, in which rises above the handle 12, to pivot downward in the direction of arrow 49. During this pivoting movement, on the one hand, the coupling sleeve 29 is rotated via the claw coupling 50, as a result of which the locking cam 47 pivots into the corresponding locking groove 44 - 46.
  • the clamping screw 26 is rotated via the tooth coupling 30, which screwed deeper into the threaded hole 28 and thereby moves the two half-shells 201 and 202 of the shell housing 20 towards one another while reducing the width of the longitudinal slot 23.
  • the collar 21 of the shell housing 20 is pressed radially against the base of the circumferential groove 22 in the motor housing 10 and the handle 12 is clamped on the motor housing 10.
  • the tensioning lever 19 strikes against a stop 51 arranged on the outside of the shell housing 20. In this end position of the clamping lever 19, the locking cam 47 is pivoted fully into the corresponding locking groove 44-46.
  • the tensioning lever 19 is to be pulled axially away from the shell housing 20 until a stop is given by compressing the compression spring 38 to its block length. In this position, the teeth 34 of the tooth coupling 30 are disengaged and the clamping lever 19 is separated from the clamping screw 26. Since the dog clutch 50 remains closed, the connection between the locking cam 47 and the clamping lever 19 is maintained. The clamping lever 19 decoupled from the clamping screw 26 is now pivoted back somewhat in the direction of arrow 49 away from the stop 51 and released again.
  • the tensioned compression spring 38 engages the coupling parts 31 and 32 of the tooth coupling 30 again, and the tensioning lever 19 and the tensioning screw 26 are again connected to one another in a rotationally fixed manner.
  • the tension lever 19 is again pivoted in the direction of arrow 49 up to the stop 51 and the toothed screw 26 is screwed further into the threaded hole 28.
  • the clamping device 124 and locking device 140 are designed separately from one another and must be operated separately.
  • the handling is a bit more cumbersome, but the design is cheaper in terms of manufacturing costs.
  • the clamping device 124 is unchanged and corresponds to the clamping device 24 in FIG. 3.
  • the coupling sleeve surrounding the clamping screw 26, which is part of the locking device 40 in FIG. 3, has been omitted, so that the first coupling part 31 of the tooth coupling 30 is supported directly on the wall section of the depression 33 in the shell housing 20.

  • the locking grooves 144 - 146 are in turn offset by 90 o , so that the handle 12 can be rotated in the same way and locked and clamped in the same rotational positions.
  • the locking cam 147 automatically falls into the respective locking groove 144-146 due to the action of the spiral spring 60, so that only the tension lever 19 has to be actuated in the manner described. Two different levers only have to be actuated to release the clamping device 24 and the locking device 140.
  • the bracket 216 of the handle 12 also functions as a clamping lever for the synchronous actuation of the clamping device 224 and the locking device 240.
