Abstract
A tool change magazine for a motor-driven machine tool, in particular a handheld machine tool with a tool which is to be driven in rotation, has an annular or drum-shaped housing. The housing is rotatable about its longitudinal axis. The tool change magazine also includes tool chambers arranged within the housing and each configured to slidably receive a tool. The housing includes regions formed from a transparent material. The tool chambers are arranged in the housing at the regions formed from the transparent material.
Claims11
A tool change magazine comprising:
- an annular or drum-shaped housing rotatable about a longitudinal axis defined by the housing, the housing having at least one region formed from a transparent material;
- and
- at least one tool chamber arranged in the housing and located at the at least one region formed from the transparent material, the at least one tool chamber configured to slidably receive a tool,
- wherein the housing includes a first housing part and a second housing part that are adjoined such that the first and second housing parts are adjacent to one another along the longitudinal axis, the first housing part being formed from a non-transparent plastics material and the second housing part being formed from a transparent plastics material,
- wherein the tool is arranged within the at least one tool chamber such that a characteristic feature that identifies the tool is visible through a circumferential outer wall of the second housing part,
- wherein the first housing part is a manually operable adjustment region configured to position the at least one tool chamber into a transfer position in which the tool is configured to be moved from or into the at least one tool chamber, and
- wherein said non-transparent first housing part and said transparent second housing part are adjoined in a non-rotatable and fixed manner relative to one another.

A motor-driven machine tool comprising:
- a machine tool housing;
- and
- a tool change magazine accommodated at least partially within the machine tool housing, the tool change magazine comprising:
- an annular or drum-shaped housing rotatable about a longitudinal axis defined by the annular or drum-shaped housing, the annular or drum-shaped housing having at least one region formed from a transparent material;
