Definitions

  • the invention relates to a drill with percussion drilling, drilling and screwing functions.
  • the invention is based on the object of being able to reliably set the various operating modes of a drilling machine even over a long period of operation.
  • the drill according to the invention is in particular a hand drill which has a drive device for driving a tool accommodated in a tool spindle.
  • the drive device comprises a drive unit, usually an electric drive motor, and a gear coupled to the drive unit, for example a planetary gear.
  • the drill can be operated in various modes, which are a percussion drilling function, a drilling function and a screwing function. In the hammer drilling and drilling function there is a fixed torque coupling between the tool spindle and the drive device, whereas in the screwing function an adjustable torque can be transmitted.
  • two latching elements which are disengaged in the drilling position and in the screwing position interlock with one another.
  • the locking elements form a notch system in which a sinusoidal or sawtooth-like wave profile is scanned and the resulting axial movement is transmitted to the tool spindle.
  • the tool spindle is advantageously kept axially adjustable relative to the gear housing.
  • a mode setting device is used to set the various operating modes, which comprises a support ring which can be rotated by manual actuation and a pressure ring which is coupled to the support ring in a rotationally fixed manner and which is supported on the gear housing.
  • the support ring is advantageously rotated with the aid of a manually operable mode setting sleeve.
  • the support ring and the pressure ring are also rotatably mounted about the longitudinal axis or spindle axis and carry out the rotary setting movement of the mode setting sleeve.
  • a rotary position of the mode setting device is assigned to each of the operating modes hammer drilling, drilling and screwing functions.
  • the pressure ring of the mode setting device supported on the gear housing is held axially displaceably on the gear housing in the screw position and axially fixed on the gear housing in the hammer drilling position and in the drilling position.
  • the support ring, with which the pressure ring is firmly connected in the direction of rotation, on the other hand, is expediently mounted fixedly in the axial direction and without the possibility of adjustment in relation to the gear housing.
  • the pressure ring can, in the event that the torque exceeds an adjustable threshold, axially lift off the gear housing, whereby the torque limit is achieved.
  • the pressure ring is axially fixed on the gearbox housing, so that there is no torque limitation in these operating modes.
  • the axial fixation is advantageously achieved via a form fit in the axial direction, the pressure ring including the support ring being rotated, in particular with the aid of the mode setting sleeve, for the transfer between the axially positively secured position and the axial adjustment option.
  • the axial form fit is preferably achieved by engaging a radially inwardly protruding projection on the pressure ring into a corresponding recess, for example a circumferential groove on the gear housing. In the screwing position with the possibility of axial adjustment, however, the projection and recess or circumferential groove are in disengagement.
  • the projection on the pressure ring and the recess or the circumferential groove on a section of the transmission housing can each engage with one another with small tolerances, so that in particular the overall tolerance in the axial transmission chain is also small. In this way, a high level of adjustment accuracy is guaranteed over a long period of operation.
  • one of the locking elements is held axially adjustable and this locking element or a component connected to the locking element is supported on an adjustment contour that is located on the support ring.
  • the adjustment contour allows a transfer of the locking element between different axial positions and thus a transfer between the locking engagement with the further locking element fixed on the housing side and a disengagement with this locking element.
  • the hammer drill function is activated when engaged, but deactivated when disengaged.
  • the adjustment contour which expediently extends in the circumferential direction on the support ring, the contour can be scanned by a relative movement between the locking element or the component held thereon and the support ring, which leads to the desired axial adjustment of the locking element.
  • the rotational movement of the support ring is here, as explained above, preferably generated by means of the mode setting sleeve.
  • the component coupled to the locking element which scans the adjustment contour on the support ring, is advantageously a locking part which is fixed to the housing in the direction of rotation, but is held axially adjustable in the housing of the drill together with the locking element.
  • the latching element and the locking part are advantageously firmly connected to the tool spindle in the axial direction, but they do not execute the rotary movement of the tool spindle.
  • the support ring and the pressure ring are advantageously designed as separate components.
  • at least one axially protruding shoulder is preferably formed on the support ring, which shoulder engages in a corresponding recess on the pressure ring.
  • the support ring at least partially engages around the pressure ring radially, so that the support ring at least partially has a larger diameter than the pressure ring.
  • a spring device with two spring retaining rings and at least one intermediate spring element is expediently provided, the spring device exerting an axial force on the pressure ring.
  • the two spring retaining rings are axially spaced from one another and are force-coupled to one another via the at least one intermediate spring element.
  • a plurality of spring elements, in particular compression springs, are advantageously arranged between the spring retaining rings distributed over the circumference.
  • the spring retainer ring of the spring device can be adjusted axially by a torque adjustment sleeve, which is expediently rotatable but is mounted axially fixed to the housing.
  • the spring retaining ring can thread into an assigned thread on the torque setting sleeve, so that when the torque setting sleeve is rotated, the spring retaining ring executes an axial adjusting movement due to the axial fixing of the torque setting sleeve. This reduces the axial distance between the first spring retaining ring, which rests directly on the pressure ring, and the second spring ring, which is acted upon by the torque adjustment sleeve. This leads to a changed preload in the at least a spring element and thus to a changed axial force which is exerted on the pressure ring. As the axial force increases, the torque that can be transmitted in the screwing function increases.
  • the spring retaining ring contacting the pressure ring expediently has a smaller diameter than the support ring and is encompassed by the support ring in the assembled position. In this way, a compact, small-sized design is achieved.
  • a detent spring element which applies a detent torque to the torque setting sleeve.
  • a detent torque is provided which applies a detent torque to the torque setting sleeve.
  • a drill 1 is shown in detail, which is a hand-held drill with the functions of hammer drilling, drilling and screwing.
  • the drilling machine 1 has a drive device which comprises an electric drive motor and a gear 2 in a gear housing 3. Via the gear 2, the rotary movement of the drive motor is transmitted to a tool spindle 4 for receiving a tool.
  • a mode setting sleeve 5 is used, which is rotatably mounted with respect to the gear housing 3 about the longitudinal axis of the drilling machine or the longitudinal axis of the tool spindle 4.
  • the functions of hammer drilling, drilling and screwing can be set by rotating the mode setting sleeve 5 accordingly.
  • a torque setting sleeve 6 is provided, which is directly connected to the mode setting sleeve 5 and can also be rotated about the longitudinal axis of the spindle.
  • the sleeves 5 and 6 can be operated independently of one another.
  • the maximum torque that can be transmitted in the screwing function of the drill can be set via the torque adjustment sleeve 6.
  • Fig. 2 the drill is shown without a mode setting sleeve 5 and without a torque setting sleeve 6.
  • the drilling machine comprises a mode setting device 7, to which the mode setting sleeve 5 ( Fig. 1 ) and on the other hand a support ring 8 and a pressure ring 9, which are each rotatably mounted on the gear housing 3.
  • the pressure ring 9 lies at a greater axial distance from the free end face of the tool spindle 4 than the support ring 8 and lies directly or on balls on an annular shoulder on the transmission housing 3.
  • the support ring 8 is firmly connected to the pressure ring 9 in the direction of rotation.
  • the support ring 8 is fixed in the axial direction essentially non-adjustable with respect to the housing, and for reasons of tolerance, an axial movement play for contact with the torque adjustment sleeve can be advantageous.
  • the pressure ring 9 can in principle perform an axial adjusting movement with respect to the housing 3 and the support ring 8.
  • the drilling machine 1 is provided with a spring device 10, which has the function of defining a maximum transmittable torque when the drilling machine is being screwed.
  • the spring device 10 includes a plurality of spring elements 11 distributed over the circumference, which are each designed as helical compression springs, as well as a first, annular spring holder 12 on the gear housing 3 and a second, parallel offset spring retaining ring 13.
  • the spring elements 11 extend between the two spring retaining rings 12 and 13.
  • the spring retaining ring 13 can be adjusted axially, as a result of which the bias of the spring elements 11 changes.
  • the first spring retaining ring 12 rests directly on the pressure ring 9 of the mode setting device 7 and applies an axial force to it against the gear housing 3. As the preload of the spring elements 11 increases, the axial force exerted by the spring device 10 on the pressure ring 9 also increases .
  • the mode setting sleeve 5 is rotatably coupled to the support ring 8, which in turn is rotatably connected to the pressure ring 9.
  • the mode setting sleeve 5 rotates, both the support ring 8 and the pressure ring 9 are rotated about the longitudinal axis.
  • Fig. 3 a section through the drill 1 is shown.
  • the tool spindle 4 is mounted rotatably with respect to the gear housing 3 via two axially spaced ball bearings 14 and 15.
  • the tool spindle 4 can also perform an axial adjusting movement with respect to the gear housing 3.
  • the second ball bearing 15 is axially fixedly connected to the tool spindle 4 and is mounted displaceably within a latching pot 16 fixed to the housing.
  • the first ball bearing 14, however, is fixed to the housing.
  • the tool spindle 4 is adjusted between the hammer drilling position and the drilling or screwing position.
  • the tool spindle 4 In the hammer drilling position, the tool spindle 4 is shifted to the left, that is, into the gear housing.
  • the latching pot 16 comes into latching engagement with a latching disk 17 which is seated in a rotationally fixed manner on the outer surface of the tool spindle 4.
  • the locking disk 17 also has the task of axially fixing the ball bearing 15, which is also seated on the outer surface of the tool spindle 4, on the tool spindle.
  • a spring element 18 is arranged inside the locking pot 16, which acts on the tool spindle 4 with force in the locking position in which the locking pot 16 and the locking disc 17 are in the locking position.
  • the spring retaining ring 13 which forms the spring device together with the first spring retaining ring 12 and the intermediate spring elements, is screwed to the torque setting sleeve 6, the torque setting sleeve 6 being axially fixed in position, whereas the spring retaining ring 13 is axially adjustable.
  • the torque setting sleeve 6 rotates, the spring retaining ring 13 moves axially due to the screw connection, whereby the preload of the spring device is changed.
  • the torque adjustment sleeve 6 locks in discrete locking positions
  • the torque adjustment sleeve 6 is acted upon by a locking spring element 20, which is held on a locking spring holder 19, the locking spring holder 19 and the locking spring element 20 being arranged in the interior around which the torque adjustment sleeve 6 engages.
  • the detent spring element 20 engages in discrete angular positions in that a detent contour on the inside of the torque adjustment sleeve 6 is acted upon by the detent spring element 20.
  • the torque adjustment sleeve 6 is axially fixed in position on the transmission housing 3. This is done with the help of a screw 21, which connects a sheet metal 22 to the gear housing 3, the sheet metal 22 axially applying force to the locking spring holder 19 against a shoulder on the torque setting sleeve 6 and in this way also axially securing the torque setting sleeve 6.
  • the support ring 8 has an adjusting contour on one end face, which is scanned by the locking part 23 and transferred to the locking disk 17.
  • Axial changes in height in the adjustment contour on the support ring 18 are transmitted to the locking disk 17 through the contact with the locking part 23, so that the locking disk 17 experiences a corresponding axial change in position. In this way, the locking engagement between the locking disk 17 and the locking cup 16 can be controlled.
  • a hump 8a protruding axially in the direction of the free end face of the tool spindle 4 is arranged on the support ring 8 and is part of the adjustment contour on the support ring.
  • Fig. 2 shows as well as Fig. 4 the hammer drilling position in which the locking part 23 is located outside the axially raised hump 8a.
  • the locking disk 17, which is connected to the locking part 23 can be in locking engagement with the locking pot 16 by the force of the spring element 18, whereby the hammer drilling function is realized.
  • the locking part 23 is rotated so far by actuation of the mode setting sleeve 5 that the locking part 23 rests on the axially raised hump 8a of the support ring 8, the locking disk 17 is axially at a distance from the locking cup 16 and is therefore out of engagement with the locking cup.
  • These disengaged positions are when drilling ( Fig. 5 ) and when screwing ( Fig. 6 , 7th ) realized.
  • the pressure ring 9 is both in the hammer drilling function ( Fig. 4 ) as well as in the drilling function ( Fig. 5 ) axially positively fixed to the gear housing 3 and can only be adjusted in the direction of rotation, so that an axial relative movement of the pressure ring 9 with respect to the gear housing 3 is excluded.
  • a radially inwardly pointing projection 24 on the pressure ring 9 engages in a circumferential groove 25 on the transmission housing 3, so that the pressure ring 9 is positively received in the circumferential groove 25 via its radially inwardly pointing projection 24.
  • a plurality of axial grooves 26 are introduced at regular intervals on the outer surface of the housing 3 and extend up to the circumferential groove 25.
  • Fig. 6 the drill 1 is shown with the first spring retainer ring 12 attached, which is part of the spring device for the axial application of pressure to the pressure ring 9.
  • Fig. 7 the drill 1 is shown without the spring retaining ring 12 for better illustration.
  • the pressure ring 9 is shown in the same circumferential position in which the drill is in the screwing position.
