Definitions
- the invention relates to an at least partially striking hand tool device, such as a hammer drill or chisel hammer, with a tool holder for a Tool like a drill bit or chisel.
- a hammer drill or chisel hammer with a tool holder for a Tool like a drill bit or chisel.
- a tool holder has a coupling sleeve with two each other diametrically opposite slot-like openings.
- Two in the breakthroughs axially and radially displaceable locking bodies are essentially cuboid executed, in addition, laterally arranged wings too deep a radial immersion Prevent the axis as well as the grooves that are brought in by means of the drive bracket Allow connection with an axially displaceable sliding sleeve, which on one of Hand rests against a sliding sleeve that can be moved against a spring force.
- the locking body lie over a locking sleeve on a damping element for damping the Spaces.
- the dislocation required to lock the tool is disadvantageous the sliding sleeve by hand.
- the object of the invention is a solution for a tool holder beating hand tool device, which no displacement by hand to lock the tool.
- the tool holder has a coupling sleeve with two diametrically opposite one another slot-like radial openings, two in the openings axially and radially displaceable locking body, a the coupling sleeve and the locking body surrounding locking sleeve with an inner, widening against the drilling direction Lateral surface, and an axially positively cooperating with the locking bodies, spring-loaded sliding sleeve. Protrudes into the interior of the coupling sleeve, the wall thickness of the coupling sleeve radially outstanding, with the inner surface of the Locking sleeve interacting locking body.
- the sliding sleeve forms at least partially radially running carrier bracket, which in at least partially radially extending driving grooves the locking body engage in an axially positive manner.
- the sliding sleeve forms an at least partially axial extending driving opening from the locking body at least partially surrounds extensively.
- the locking bodies are advantageously on the inner Shell surface of the locking sleeve and partially protrude into the interior of the coupling sleeve as well as optionally in diametrically opposed, axially closed locking grooves one accommodated in the coupling sleeve of the tool holder Tool shank.
- the locking bodies for dissipation of the empty stroke energy are advantageously located via the locking sleeve on a damping element made of elastomeric material on.
- the sliding sleeve and the Driving grooves of the locking body In the operating state, the sliding sleeve and the Driving grooves of the locking body, the locking body with its axial Partial area pressed onto the front side of the locking sleeve and radially over the conical surface is positively supported, the locking body partially radially in the locking groove of the tool shaft engages and the tool is thus axially limited movably locked.
- the locking body can now also on the side edges of the Locking groove transmit a torque.
- the tool strikes with its device-side, axially limiting End face of the locking groove on the end face of the locking body on the device side. About the axial tool-side part of the locking body and the device side Face of the locking sleeve, this is pressed onto the damping element and thus the Empty stroke introduced into the tool holder.
- the locking bodies become by the sliding sleeve axially abutting the actuating sleeve axially from the Area of effect of the inner lateral surfaces are drawn and by that in the coupling sleeve located tool shank radially in a release position when that Tool is pulled out of the coupling sleeve. In the release position, the Locking body held by the sliding sleeve.
- a hand tool device 1 which is only partially shown, has a tool holder 2 with a coupling sleeve 3, two diametrically opposite slot-like radial openings 4, 4 ', two axially and radially displaceable in the openings 4, 4' Locking body 5, the coupling sleeve 3 and the locking body 5 surrounding locking sleeve 6 with an inner, radially expanding on the device side Lateral surface 7, and an axially positively cooperating with the locking bodies 5, spring-loaded sliding sleeve 8.
- A protrudes into the interior of the coupling sleeve 3 Wall thickness of the coupling sleeve 3 radially projecting on the inner lateral surface 7 of the Locking sleeve 6 adjacent locking body 5.
- the sliding sleeve 8 forms an at least partially axially extending Driving opening 9 from which the locking body 5 at least partially circumferentially surrounds.
- the locking bodies chamfered towards the axis A towards the tool and the device 5 protrude into the diametrically opposite, axially closed Locking grooves 10 one in the coupling sleeve 3 of the tool holder 2nd received tool shank 11, which forms a chamfer 12 on the end face.
- the locking body 5 lies on the locking sleeve 5 on a damping element 13 made of elastomeric material.
- An actuating sleeve 14 is axially adjacent on the tool side the sliding sleeve 8.
- the locking body 5 forms an axial within its length transversely lying, tool-side partial surface 15.
- the sliding sleeve 8 forms an at least partially radially extending Driving bracket 16, which in at least partially radially extending driving grooves 17th the locking body 5 engage in an axially positive manner.
- 3 is the locking body 5 shown in cross section perpendicular to the axis A. with two symmetrically opposite, segment-like tapering, not parallel side surfaces 18, 18 'formed.
