Definitions
- the invention is based on an electric hand machine tool according to the preamble of claim 1.
- DE-OS 42 35 278 discloses a generic hand-held power tool, the file-like insert tool of which is driven back and forth by an output shaft carrying an eccentric via a driver.
- the output shaft is set in motion by an electric motor via an angular gear, the output shaft being angled by approximately 90 ° with respect to the motor shaft, no adjustment means for adjusting the angular gear play, ie the play of the output shaft relative to the motor shaft or the axial play of the Has output shaft opposite the housing.
- the upper end of the output shaft is received in the upper region of the transmission housing by an axial and radial force-absorbing roller bearing and the lower shaft end in the lower region of the transmission housing by a needle bearing.
- the division plane of the housing runs vertically and evenly in the working position, at least one bearing point of the output shaft being in the region of the division plane, i.e. that the bearing seat is also divided.
- the forces transferred from the replacement tool to the housing can lead to deformation of the housing edges in the region of the parting plane. This in turn can deform the bearing seats of the output shaft and thus interfere with the transmission function.
- the clamping means for the insert tool can be moved from the outside into the clamping and releasing position via operating means, but must also be able to follow the movement of the driver and the tool.
- the clamping means for coupling the insert tool to the driver are designed to be relatively complex.
- the electric hand machine tool according to the invention with the characterizing features of claim 1 has the advantage that the output shaft can be optimally adjusted in relation to the drive shaft and relative to the housing. This creates an effective tolerance compensation, which enables the use of roughly tolerated, cost-effectively manufactured parts for the housing and the transmission.
- a simple adjusting means is created which is designed as a bearing bush, axially adjustable in the housing, in particular with a steep thread, and that the bearing bush carries at least one ring wedge on the underside of an upper, radial collar, to which a housing-side counterpart Rmgkeil is assigned as a support surface.
- the actuating means can be secured against unintentional adjustment with an anti-twist device relative to the housing, the anti-twist device in a particularly simple design consisting of an externally toothed clamping ring which, on the inside, has a double face on the lower outside of the bearing bush on the lower outside of the bearing bush facing the collar or the ring wedge overlaps the side.
- a compression spring is supported on the anti-rotation lock designed as an adjusting ring and holds it in place relative to the bearing bush or the housing means that the adjusting means is particularly wear-resistant.
- the pushbutton is reliably returned to its starting position when it is released or when the tool is clamped.
- the detachable arrangement of the anti-rotation device on a side, in particular facing the tool and accessible from the outside, enables the axial play of the output shaft to be adjusted without dismantling the hand-held power tool.
- the support is simple and inexpensive in that the output shaft is supported via a spring-mounted, axially displaceable ball relative to the housing and that a compression spring is arranged in the upper housing shell, which engages around a pin on the housing side and at the other a pin carrying a support disc and yourself about supports the support disc with respect to the ball, which is seated in an end recess in the upper end of the output shaft and protrudes beyond the edge of the recess.
- the bearing point in the upper housing shell can compensate for the misalignment of the output shaft by arranging an annular slide bearing for supporting the upper end of the output shaft, the tread of which is conical.
- the slide bearing particularly effectively compensates for the misalignment of the output shaft by the fact that the tread of the The sliding bearing runs cylindrically in its upper region over a length of approximately 2 to 3 mm and then merges downward into a conical region of approximately 7 mm in length that opens at an angle of approximately 5 °.
- the conical opening facilitates the insertion of the output shaft into the slide bearing during the assembly of the hand tool mechanism
- the driver can be moved out of engagement with the insert tool by displacement, whereby the insert tool is separated from the drive and can be easily removed, operation can be carried out with simple means, namely via a pushbutton with which the driver can be displaced by hand .
- the insert tool is guided in the area of its clamping end in a longitudinal guide with little play and friction and thus relieves the drive and the housing of work-related transverse forces and thus changing frictional influences by the longitudinal guide encompassing the flat, clamping-side area of the insert tool and securing it against twisting when working.
- a sealing cap covers the opening of the front area of the housing through which the shaft of the insert tool hm passes. It serves as a sliding guide and vibration damping for the insert tool. Because the insert tool has a cutting edge running transversely to its direction of movement, it is particularly advantageous as a chisel, spatula or the like. applicable.
- the longitudinal guide is securely locked in the housing shell by a box-like profile encompassing it with a receiving tunnel open at the back and front for the passage of the insert tool.
- the housing is particularly stable in terms of deformation in that it is formed from two housing shells which are assembled with the parting plane running horizontally in the working position, the output shaft being rotatably mounted in one bearing in each of the two housing shells.
- the stability of the housing is increased by the shells and the dividing plane formed by dividing edges in the region of the neck - viewed in the working position - being bent downwards and the folding serving as a handle.
- the stiffening of the housing increases as a result of the operator's hand being gripped and as a result of the operating forces when working, as a result of which the housing shells are quasi entangled and firmly braced against one another.
- a further advantage is that the clamping means for fastening the insert tool consist of only a few, inexpensive individual parts, with which the insert tool can be operatively connected to the driver in a few simple steps and can therefore also be exchanged quickly.
- the risk of the operator being injured on the cutting edge of the insert tools is reduced by the ease of use.
- the simplified tool change thus contributes to improving work safety.
- the driver itself detachably engages with a projection in the recess of the clamping of the insert tool, a particularly simple, easy-to-use clamping system for scraping tools designed as an insert tool is created.
- the push button is held in the release position for the insert tool in relation to the housing and the locking means can be released again by the tool when it is inserted, the push button does not have to be held down during the insertion of the tool. This means that one hand of the operator is only available for holding the handheld power tool and the other hand for tool removal. This makes changing the insert tool easier.
- the driver is designed like a connecting rod with a head that bears a projection, its undesired rotation inside the housing is avoided and a particularly quiet, low-wear barrel of the hand tool is achieved, the head damping vibration in the notch in the longitudinal guide is led.
- the axially parallel arrangement of the driving projection for the eccentric pin limits the rotatability of the driver with respect to the eccentric pin with a radial distance from the recess and thus reduces friction and wear between the eccentric pin, the driver and the insert tool. It is advantageous that the recess of the clamping end of the insert tool is circular and has essentially the same diameter as the projection of the driver.
- the long guide is arranged as a separate body and cannot be displaced inside the housing as soon as the housing shells are screwed together.
- the longitudinal guide is supported in the direction of movement of the guided insert tool against a front wall of one of the housing shells and is therefore captive and free of play but at the same time easily replaceable, because the longitudinal guide in the front region after the housing shells have been lifted slightly apart can be removed from the housing.
- the longitudinal guide reads a separate body, it absorbs the bending forces transmitted to the housing via the shaft of the insertion tool and transmits them over a large area to the housing, so that this is only exposed to low bending and torsional forces and m lightweight construction can be carried out, rolling elements on both ends of the guide slot of the longitudinal guide reduce the wear or the friction between the longitudinal guide and the tool, in that only rolling instead of sliding friction is permitted there.
- the insert tool can be a chisel, scraper, spatula or the like. made of metal, eg hard metal or HSS steel sem. It is very versatile, for example for carving and removing of paint, wallpaper, carpet adhesive, foam printing, needle felt, PVC, also for cleaning work, e.g. removal of dirt, adhesive and glue, plaster, gypsum, filler, putty, coloring and silicone residues as well as mortar and Concrete residues on building boards Finally, it can also be used to prepare substrates, eg screed and concrete preparation, smoothing caterpillars and noses, grouting cracks, removing tile adhesive
- substrates eg screed and concrete preparation, smoothing caterpillars and noses, grouting cracks, removing tile adhesive
- the replacement tool has a flat, in particular rectangular, cross-section in the area of the shaft, which can be guided in a longitudinal guide, in particular in a flat slot, and which absorbs elastic, leaf spring-like, bending forces when scraping. This ensures that the replacement tool is secured against rotation about its longitudinal axis and springs when Operation of the scraper between the workpiece and the operator pushing off

- the bearing point of the output shaft 50 remote from the tool consists of a ring-like slide bearing 40 which can be inserted into a cylindrical bearing receptacle 38 0 of the housing shell 12, in particular of sintered material, a compression spring 42, a support disk 44 and a ball 46 which are in a central recess 43 in the upper end face of the output shaft 50 is mounted.
- the compression spring 42 engages around the top, i.e. one end, a housing-fixed mandrel 41 and below, i.e. at the other end, a pin 44 'carrying a support disc 44 and is supported via the support disc 44 with respect to the ball 42, which in the
- the plain bearing 40 has a tapered or spherical inner running surface 47 for receiving the upper bearing end of the output shaft 50. Because of this, and also because of the axial support on the ball 46
- the output shaft 50 can be guided inclined by a certain amount with respect to the central axis of the plain bearing 40 without play, without the plain bearing 40 being destroyed in the process. This enables the use of roughly tolerated manufactured parts for the scraper 10, its radio

- the driver 68 has the head part 65 which carries the projection 70 and which engages rotatably in the notch 83 of the longitudinal guide 82 which serves as a guide slot. This ensures that the head 65 and thus the driver 68 is also secured against rotation within the housing 11 when the scraper 10 is not equipped with a tool 88, 288 and when in this state the mo gate 16 is started.
- FIG. 10 the upper and lower housing shells 12, 14 are shown pulled apart parallel to the axis, the inclined course of the dividing edge 15, which is bent at the front, being clear in both housing shells.
- the upper housing shell shows particularly clearly the mandrel 41 and the concentric bore 45 for receiving the compression spring 42, not shown here but shown in FIGS. 1 to 3, 5, 6, which in turn has the pin 44 'with the washer 44 supports for axial support on the ball 46 or on the output shaft 50.
