Definitions

  • the invention relates to a hand-held, motor-driven device for grinding, polishing, rust removal or the like processing of surfaces, with a drive motor arranged in a motor housing, which has a rotating motor shaft during operation, which drives a tool holder for a particularly disk-shaped machining tool a handle connected to the motor housing for holding the device, and with an additional guide handle which is arranged in the direction of the axis of rotation of the tool holder at least approximately at the same height as the handle and protrudes laterally from the motor housing and which is adjustable in circumferential direction with respect to the axis of rotation of the tool holder Motor housing is connected and opposite this in different circumferential positions can be detachably fixed.
  • a device of this type is disclosed in JP-A-55/112759. It has a motor housing that also forms a handle on which the device can be held during machining. The motor housing receives the drive motor, to the motor shaft of which a respective machining tool is connected.
  • An additional guide handle which protrudes from the side of the motor housing, allows the device to be held with both hands and thus more secure guidance during machining. Tilting of the machining tool in relation to a surface to be machined can therefore be largely excluded. Should a force nevertheless act on the device which it intends to throw off the track, such conditions can be counteracted optimally by holding the handle. Even parts of workpieces that are difficult to access can be processed very precisely.
  • the adjustment option of the handle allows adaptation to left-handed or right-handed operation. If the handle is not required, it can be removed.
  • Disassembly of the handle requires releasing a handle plate from the concave Part of a section of a gearbox housing, for which a band has to be loosened and a cover hood has to be removed.
  • the handle extends at an angle to the motor shaft and protrudes laterally from the motor housing, and that the handle has a receiving opening located in the adjustment path of the guide handle, into which the guide handle can be at least partially submerged.
  • the handle protruding from the side of the motor housing allows the device to be held securely during machining. If the guide handle is not required during processing, it can be sunk into the receiving opening of the guide handle, so that it assumes a non-obstructing position without having to be removed.
  • DE-A-25 59 132 shows a device which has a handle which can be swiveled by a maximum of about 300 °. He can be put in a position in which it lies on the side of the motor housing. However, sinking into the handle is not possible.
  • the device described in US-A-4 643 263 has two handles, both of which are designed as swivel handles. An at least partial sinking of one handle in the other is not possible.
  • the guide handle is expediently arranged on the motor housing in a continuously adjustable manner and can be fixed in any circumferential position on the motor housing.
  • the adjustment range preferably extends over 36o °.
  • the guide handle itself is preferably designed as a handle for its adjustment and releasable fixing relative to the motor housing. This saves additional fasteners. It expediently forms a rotary member to be rotated for loosening or fixing, the axis of rotation preferably coinciding with the direction in which it protrudes from the motor housing.
  • the guide handle is arranged on a clamping band surrounding the motor housing in the circumferential direction with respect to the axis of rotation.
  • this clamping band can expediently be braced or released from the motor housing by acting on the guide handle.
  • the device can easily be placed on and / or guided along any reference surface during a machining process. This increases the precision of the machining processes even more in special cases.
  • the device can be connected to a suction device for dust, chips or similar contaminants, hereinafter referred to as a dust suction device.
  • a dust suction device This effectively protects the work area as well as the environment from dirt.
  • the means for dust extraction are processing cumbersome and can contribute to an increase in weight of the device.
  • the device can have a cover part which can be detachably fixed in a cover position with partial covering of the gripping surface on the handle, wherein it forms a suction channel of a dust extraction device opening into the working area of the held processing tool and at the same time with its outer surface as a gripping surface section takes the place of the covered handle section.
  • the handle When the cover is removed, the handle is in its original shape. At times when dust extraction is desired, only the cover part needs to be attached, so that there is a suction channel to which, for example, a suction unit can be connected. Since the outer surface of the cover part takes over the gripping surface function, the handling of the device does not change compared to the removed cover part. This is advantageous for the user.
  • the removable cover part can be realized with practically all motor-driven processing devices or power tools. However, it is particularly advantageous in connection with a device of the type in question here, in which the weight saving plays a significant role.
  • the device shown in the drawing is designed as a hand-held device and is used for grinding, polishing, brushing, rust removal or other comparable work on any object surface.
  • the type of processing mainly depends on the processing tool operated with the device. You could also call the device a hand tool.
  • the device has a motor housing 1 with a substantially circular cylindrical shape on the outside.
  • the two end faces represent the top 2 and the bottom 3 of the motor housing 1.
  • an electric drive motor 4 which is only indicated by dashed lines and which has a driven motor shaft 5 which projects from the motor housing 1 on the underside 3.
  • a tool holder 6 At the free end of the motor shaft 5 there is a tool holder 6, indicated only by dashed lines, which in the exemplary embodiment is formed by a threaded section which cooperates with a clamping nut.
  • a disc-shaped machining tool 7 is detachably and coaxially fixed on it.
  • the exemplary embodiment is a grinding plate covered with an abrasive coating 8.
  • the machining tool 7 Since the machining tool 7 is fixed directly to the motor shaft 5, a compact construction results, with the drive motor 4 being located centrally above the machining tool 7. It is preferably a gearless arrangement, so that the motor speed coincides with the speed of the machining tool 7 and there is no need for weight-increasing, noisy gear means such as meshing gears during operation. While maintaining the advantages, the machining tool 7 could also be seated on a linear extension of the motor shaft 5. In any case, an arrangement is preferred in which the axis of rotation 9 of the machining tool 7 and tool holder 6 coincides with the motor shaft 5, that is to say the axis of rotation 13 thereof.
  • a handle 15 is arranged laterally, in the region of the peripheral surface 14 of the motor housing 1 formed by the cylindrical jacket. It is firmly and permanently connected to the motor housing 1, in particular in that it is formed in one piece with the motor housing 1. In the exemplary embodiment, it has an essentially rod-like shape and extends at an angle to the motor shaft 5, so that it projects laterally from the motor housing 1. 4, the longitudinal axis 16 of the handle 15 expediently runs radially with respect to the circumferential surface 14. In the side view according to FIG. 2, the longitudinal axis 16 can run at right angles to the axis of rotation 13, but is preferably, as shown, slightly inclined, so that the handle 15 rises slightly upwards towards its free end 17. In the exemplary embodiment, the handle 15 starts in the section of the peripheral surface 14 that follows the underside 3. Since its width measured in the height direction is less than the height of the motor housing 1, this protrudes with an upper cylindrical end section 18 over the handle 15.
  • the diameter of the machining tool 7 expediently corresponds at least substantially to the diameter of the motor housing 1.
  • the device also has a second handle, which is referred to as a guide handle 19, since it is gripped by the user mainly for guiding the device.
  • the rigid handle 15 serves rather to hold the device in general and to transmit the contact pressure to a surface on which the machining tool 7 is applied.
  • the guide handle 19 is also arranged laterally, in the region of the circumferential surface 14, on the motor housing 1 and protrudes radially from the latter in particular radially to the axis of rotation 13. Its longitudinal extent, measured in the direction of the free end, is less than that of the handle 15, that is, it projects less than this from the motor housing 1.
  • the guide handle 19 has an essentially button-like shape.
  • a great advantage of the guide handle 19 is that it is adjustable relative to the motor housing 1 in the circumferential direction with respect to the axis of rotation 9.
  • the direction of adjustment is indicated in FIGS. 1 and 4 by the double arrow 20.
  • the guide handle 19 can be releasably fixed with respect to the motor housing 1, forming a practically rigid handle in the fixed state.
  • the guide handle 19 assumes a circumferential position 21 diametrically opposite the handle 15. It stands in the opposite direction to the handle 15 from the motor housing 1.
  • the separate guide handle 19 is held on the motor housing 1 by means of a clamping band 22.
  • This is placed around the motor housing 1 in a coaxial arrangement, wherein it extends in the circumferential direction with respect to the axis of rotation 9 and thus in the direction of adjustment 20 and bears against the circumferential surface 14 .
  • the clamping band 22 can either be tensioned such that it is immovably fixed relative to the motor housing 1, or it can be released so that it together with the guide handle 19 in the direction of adjustment 20 up to the desired circumferential position 21 relative to the motor housing 1 is rotatable.
  • the advantage here is that the guide handle 19 can be adjusted continuously and can be locked in any possible circumferential position.
  • FIG. 4 only a few of the possible circumferential positions are selected as examples.
  • the clamping band 22 assumes a clearly defined position in the direction of the axis of rotation 9 and thus in the height direction 23 of the device, a not shown in the peripheral surface 14, at least partially along the peripheral surface 14 extending recess into which the clamping band 22 is immersed with at least part of its thickness.
  • the flanks of the depression form stops which prevent the clamping band 22 from moving in the height direction 23 without disturbing the movement in the adjustment direction 20.
  • the structure of the guide handle 19 provided in the exemplary embodiment will be explained below. Accordingly, it comprises a threaded part 27 which, starting from the already mentioned outer surface 28 of the clamping band 22, extends radially outwards. In the exemplary embodiment, it is formed by the shaft of a screw 29 which is fixedly placed on the outer surface 28 with the head surface 30 opposite the shaft. For example, a welded or adhesive connection can be provided for the firm connection.
  • a screw part 31 is placed on the threaded part 27 and can be screwed back and forth on the threaded part 27 by turning it according to the double arrow 32 shown in FIG. In the embodiment it has the shape of a ball.
  • a pressing element 33 which is supported on the one hand on the screw part 31 and on the other hand on the peripheral surface 14 of the motor housing 1.
  • it is sleeve-shaped and axially adjustably attached to the screw 29.
  • the pressing surface 34 cooperating with the screw part 31 is spherically complementary to the spherical shape in the exemplary embodiment, so that the pressing force is optimally transmitted.
  • the pressing element 33 is provided with a recess 35 which is continuous in the longitudinal direction of the band and into which the clamping band 22 can dip, the parts of the pressing element 33 lying next to the recess 35 forming pressing parts 36 which support against the peripheral surface 14.
  • the through opening 37 of the pressing element 33 which allows it to be plugged onto the screw part 31, is widened in the area adjacent to the recess 35 in such a way that the screw head is also received.
  • the guide handle 19 of the embodiment is designed as a rotary handle.
  • the pressing element 33 with its pressing parts 36 is pressed against the peripheral surface 14, as a result of this support the clamping band 22 connected to the threaded part 27 being pulled radially outward in the connection area with the threaded part 27.
  • the clamping band 22 is tensioned against the motor housing 1, particularly in the regions diametrically opposite the guide handle 19.
  • the adjustment range of the guide handle 19 extends over 360 degrees. It can therefore be arranged at any point along the peripheral surface 14.
  • the guide handle 19 is arranged at the same height as the attachment point of the handle 15, viewed in the height direction 23. As can be clearly seen from FIG. 2, the guide handle 19 assumes a position in the region of the middle of the height of the handle 15.
  • the width of the guide handle 19 measured in the height direction 23 is less than the correspondingly measured width of the section 38 of the handle 15 directly adjoining the motor housing 1.
  • This section 38 is provided with a receiving opening 39 which passes through the handle 15 in the circumferential direction with respect to the axis of rotation 9. Their cross-sectional contour is selected so that the handle 19 fits through.
  • the guide handle 19 comes to lie very close to the machining tool 7 and thus to the working area 45 of the device. This allows the device to be guided precisely during a machining operation. At the same time, there is the possibility of positioning the guide handle 19 freely at any point on the circumference of the motor housing 1 by the handle 15.
  • the actual task of the receiving opening 39 is, however, to receive the guide handle 19 in a rest position if, owing to special circumstances, it is not required or is a hindrance in the context of the current processing.
  • This rest position is shown in FIG. 4 at 21 ′′.
  • the guide handle 19 comes to rest completely sunk in the handle 15, so that the device has a shape which corresponds to that of a handle-less device without complex removal of the handle 19.
  • the guide handle 19 and in particular its screw part 31 are easily accessible in order to be in the rest position 21 '' to clamp against the motor housing 1 and to be able to loosen it again later. It may also be expedient to match the width of the guide handle 19 to the width of the handle 15 in such a way that the screw part 31 in the rest position 21 ′′ slightly projects beyond the lateral outer surfaces 46 of the handle 15 on both sides and is therefore easy to grasp (not shown). .
  • the receiving opening 39 is closed apart from the lateral openings, in an embodiment not shown it is open at one point on its circumference, in particular towards the top 2. This allows an even better handling of the guide handle 19 in the rest position 21 ′′.
