Motor-powered machine tool, in particular a hand-held machine tool

摘要

A motor-powered machine tool includes a drum-like tool-changing magazine having tool chambers. The magazine is arranged inside a housing, and when the tool is in a change position, one of the tool chambers of the tool-changing magazine is aligned with a tubular tool holder. The tool further includes a sliding element configured to slide a tool from the tool-changing magazine into the tool holder and from the tool holder back into the tool-changing magazine. The sliding element is movable in a longitudinal direction of the tool holder. In at least one embodiment, the sliding element is coupled with a gearbox system which includes at least one toothed gear. The rotational motion of the toothed gear is translated into linear movement of the sliding element.

1. A motor-powered machine tool, comprising:
a housing; a tubular tool receptacle; a drum-like tool change magazine having a plurality of tool chambers, the tool change magazine arranged within the housing and configured to selectively position each of the tool chambers in a change position in which a longitudinal axis of the positioned tool chamber is coincident with a longitudinal axis of the tool receptacle; a sliding element configured to be moved relative to the tool receptacle in a direction extending parallel to the longitudinal axis of the tool receptacle and configured to act upon a tool from the tool change magazine and slide the tool into the tool receptacle and slide the tool from the tool receptacle back into the tool change magazine; a gear-mechanism device coupled to the sliding element and including at least one gearwheel, wherein rotational movement of the at least one gearwheel is converted into a linear movement of the sliding element; and an adjusting element mechanically coupled to the at least one gearwheel for purely mechanical actuation of the at least one gearwheel by the adjusting element, wherein manual actuation of the adjusting element causes the adjusting element to rotate the at least one gearwheel.
