Power tool with a clamping mechanism for clamping a tool

摘要

The invention discloses a hand-held power tool including a housing with a spindle head. A tool spindle can be driven in rotary oscillation about its longitudinal axis and, at its tool-side end, is configured to carry a tool. The tool spindle has a clamping mechanism, which is configured to move a positioning element between a clamping position, in which a tool that is to be carried can be fixed to the tool spindle, and a release position, in which the tool can be released. The clamping mechanism has an actuating mechanism having an actuating element configured as a slide having an engaging surface for axially moving the positioning element to move the clamping mechanism between the clamping and the release positions when the actuating element is moved.

主权项

1. A hand-held power tool, comprising:
a housing having a spindle head; a tool spindle having a longitudinal axis and being be driven rotatingly oscillatingly about its longitudinal axis, said tool spindle further having a drive-side and a tool-side; a tool receptacle arranged on said tool-side of said tool spindle for receiving a tool; a first bearing arranged within said spindle head on said drive-side of said tool spindle; a second bearing arranged within said spindle head on said tool-side of said tool spindle; and a clamping mechanism comprising a positioning element arranged within said tool spindle axially displaceably between a clamping position for clamping a tool on said tool receptacle, and between a release position for releasing a tool from said tool receptacle; wherein said tool spindle is supported within said spindle head at least by means of said first and second bearings; wherein said clamping mechanism further comprises an actuating mechanism having an actuating element being configured as a slide, said slide extending substantially perpendicularly to said longitudinal axis; wherein said slide further comprises a engaging surface being disposed between said first and second bearings; wherein said engaging surface is configured as an inclined surface, which engages said positioning element for moving said positioning element axially between said clamping and said release positions when said actuating element is moved; and wherein said positioning element further comprises at least one guide roller for engaging said engaging surface of said actuating element.
