Definitions
- the invention relates to a machine tool according to the preamble of claim 1.
- a locking device which has a locking bolt which is guided in a housing in a rotationally fixed manner relative to the drive shaft and which can be brought into engagement with a toothing connected to the drive shaft in a rotationally fixed manner via an actuating button.
- EP 0 904 896 A2 discloses a grinding machine tool holder for a hand-held worm grinding machine.
- the angle grinder has a drive shaft that has a thread on the tool side.
- the grinding machine tool holder has a driver and a clamping nut.
- the driver is pushed onto an collar of the drive shaft with an assembly opening and clamped non-positively against a bearing surface of the drive shaft via the clamping nut.
- the driver has a collar that extends in the axial direction on the tool side and has recesses on its outer circumference radially on two opposite sides that extend in the axial direction to a base of the collar.
- a groove extends in each case against the drive direction of the drive shaft on the outer circumference of the collar.
- the grooves are closed against the drive direction of the drive shaft and taper axially from the recesses against the drive direction of the drive shaft.
- the grinding wheel has a hub with an assembly opening in which two opposite, radially inward-pointing tongues are arranged.
- the tongues can be more axial
- a stopper which is movably mounted in an opening in the axial direction. In a working position with the grinding wheel pointing downwards, the stopper is deflected by gravity axially in the direction of the grinding wheel, closes the groove in the direction of the recess and blocks a movement of the tongue located in the groove in the drive direction of the drive shaft.
- the invention is based on a tool holder, in particular for a hand-held angle grinding machine or a hand-held circular saw, with a driving device, via which an insert tool can be effectively connected to a drive shaft, and with a locking device, via which the drive shaft is mounted and / or dismantled with an actuation button the insert tool can be locked.

Due to the actuating button rotating with the drive shaft during operation, it can be reliably avoided that the actuating button is misused to brake the drive shaft. A running out of the application tool due to an unintended large braking torque and a resulting injury Driving can be safely avoided and wear on the locking device can be reduced.
- the solution according to the invention can be used with various tool holders which appear to be useful to the expert.
- the insert tool it is particularly advantageous for the insert tool to be operatively connected to the entrainment device via at least one latching element which is movably mounted against a spring element, which latches in an operating position of the insert tool and fixes the insert tool in a form-fitting manner.
- a particularly secure attachment of the insert tool can be achieved by the positive connection. Furthermore, a large deflection of the latching element can be made possible with the movably mounted latching element during assembly of the insert tool, whereby on the one hand a large overlap between two corresponding latching elements and a particularly secure form fit can be achieved and on the other hand a well audible latching noise can be achieved, which Operator advantageously signals that the latching process has been completed as desired.
- a simple and inexpensive tool-free quick-action clamping system can be created, in which the movement of the latching element and / or the movement of a component moved with the latching element can be used for the locking device of the drive shaft, in a particularly structurally simple manner if the latching element is in the axial direction is slidably mounted against the spring element.
- One or more components can be used for fastening the insert tool and additionally for the locking device, which means additional components, installation space, assembly effort and cost Most can be saved, in particular by connecting the locking element and / or a component that is movably mounted with the locking element by the actuation button to the second part that is non-rotatable with respect to the axis of rotation of the drive shaft and that the drive shaft can be locked in the circumferential direction.
- the locking element can fix the insert tool directly or indirectly via an additional component in a form-fitting manner, for example via a locking lever or plunger, which is coupled to the locking element, rotatably and / or axially displaceably mounted, etc.
- the locking element can directly and / or indirectly form-fit the insert tool in different directions fix, such as m radial direction, m axial direction and / or particularly advantageously m circumferential direction. It is also possible for the insert tool to be positively fixed in a second direction, for example in the circumferential direction, by a component separated from the catch element by the form-fitting fixing of the insert tool with the detent element m, for example m radial direction.
- the movably mounted latching element can be designed in various forms that appear useful to those skilled in the art, for example as an opening, projection, pin, bolt, etc., and can be arranged on the insert tool and / or on the driving device.
- the latching element can itself be movably mounted in a component in a bearing point, for example in a flange of the driving device or in a tool hub of the insert tool.
- the latching element can also advantageously be firmly connected to a component that is movably mounted in a bearing point, positively and / or cohesively, or can be made in one piece with it, for example with a component mounted on the drive shaft or with a tool hub of the insert tool.
- the driving device can be at least partially designed as a removable adapter part or can be non-positive, positive and / or
- the tool holder can be used to fasten various insert tools that appear to be useful to a person skilled in the art, such as insert tools of a rotary grinder for cutting, grinding, roughing, brushing, etc.
- An inventive tool holder can also be used to fasten a sanding plate of eccentric sanding machines.
- the latching element and / or the latching element movable with the latching element Component is positively connected to the second, rotationally fixed with respect to the axis of rotation of the drive shaft, whereby a safe locking of the drive shaft can be achieved comfortably with little effort.
- a non-positive locking is also conceivable, in particular in the case of the proposed tool holder, in which only small torques have to be absorbed by the locking device during assembly and disassembly of the insert tool. In the event of an accidental actuation of the actuation button during operation, less wear can be achieved compared to a positive locking device.
- the latching element can be released from its latched position with a release button and, in particular, moved against the spring element, an independent loosening of the latching connection, for example by a braking torque, can be reliably avoided and safety can be increased. Operation of the insert tool in two circumferential directions can be made possible in principle, and the ease of assembly and disassembly of the insert tool can be increased.
- the actuation button and the release button of the locking device are designed in one piece. Additional components, weight, assembly effort and costs can be saved and, in particular, the comfort can be increased and operation can be simplified.
- An operator can unlock the insert tool in one direction by pressing the actuation button and at the same time lock the drive shaft.
- At least one latching element which extends in the axial direction is advantageously fastened in a component which is mounted displaceably on the drive shaft against the spring element.
- One and particularly advantageously several locking elements can be guided well over a large bearing surface on the drive shaft.
- Tilting of the latching elements and movement of the latching elements relative to one another can be reliably avoided, and a desired spring force for a latching process can be achieved with a spring element, which can advantageously be arranged concentrically rotationally symmetrically.
- the component and / or the locking elements fastened in the component can advantageously be connected to the second part, which is rotationally fixed with respect to the axis of rotation of the drive shaft, and torques that occur during assembly and disassembly can advantageously be supported.
- At least one locking element is on a disk-shaped component and / or the first part that is operatively connected to the drive shaft in the direction of rotation is on a disk-shaped component and / or if at least two elements are integrally molded on a disk-shaped component in the axial direction, additional components can be added , Assembly effort and costs can be saved. Furthermore, press connections between individual components and the resulting weak points can be avoided. drawing
