Abstract
A portable machine tool comprises a main spindle and a machine body that is rotatable relative to the main spindle. A take-off shaft is mounted in the machine body and is rotatable relative to the machine body, and a rocker arm is rotatable about the axis of the take-off shaft. A cam and follower mechanism converts rotation of the machine body to reciprocating rotation of the rocker arm, and a releasable clutch mechanism that is effective between the rocker arm and the take-off shaft can be switched between a first state in which it converts reciprocating rotation of the rocker arm to unidirectional rotation of the take-off shaft and a second state in which reciprocating rotation of the rocker arm has no effect on the take-off shaft.
Claims11
A portable machine tool comprising:
- a main spindle having a central axis,
- a machine body that is rotatable relative to the main spindle about said central axis,
- a take-off shaft that is mounted in the machine body and is rotatable relative to the machine body about a second axis,
- a first coupling member that is rotatable about said second axis,
- a mechanism for converting relative rotation of the machine body and the main spindle about said central axis to reciprocating rotation of the first coupling member about said second axis, and
- a converting means effective between the first coupling member and the take-off shaft and having at least a first state in which it converts reciprocating rotation of the first coupling member to unidirectional rotation of the take-off shaft in a first rotational sense and also having at least a second state in which the first coupling member is uncoupled from the take-off shaft, and
- a switch means for switching the converting means between its first state and its second state.
A portable machine tool comprising:
- a main spindle having a central axis,
- a machine body that is rotatable relative to the main spindle about said central axis,
- a take-off shaft that is mounted in the machine body and is rotatable relative to the machine body about a second axis,
- first and second coupling members that are rotatable about said second axis,
- a mechanism for converting relative rotation of the machine body and the main spindle about said central axis to reciprocating rotation of the first and second coupling members about said second axis, and
- a converting means effective between the first and second coupling members and the take-off shaft and having a first state in which it converts reciprocating rotation of the first coupling member to unidirectional rotation of the take-off shaft in a first rotational sense and the second coupling member is uncoupled from the take-off shaft, a second state in which it converts reciprocating rotation of the second coupling member to unidirectional rotation of the take-off shaft in a second rotational sense, and a third state in which the first and second coupling members are uncoupled from the take-off shaft, and
- a switch means for switching the converting means among its first, second, and third states.
