Embodiment Construction

[0214] Machine tool 10 is designed, for example, as a sawing machine. Machine tool 10 is in particular an immersion saw.

[0215] The power tool 10 has a drive unit 11 with a machine housing 12 in which a drive motor 13 is accommodated. The drive motor 13 drives the tool receptacle 14 directly or via a transmission not shown in the drawing. In the drawing, a working tool 15 is fastened on the tool receptacle 14 , in any case detachable fastening is possible. The working tool 15 includes, for example, a saw blade or another separating tool. In this connection it should be mentioned that the exemplary embodiment also represents other power tools of the movable type, that is to say for example manually guided parting cutters, milling cutters or the like.

[0216] The machine tool 10 is movable, that is to say it can be supplied with electrical current via the power supply connection 17 . The drive motor 13 is an electric drive motor, wherein alternatively, of course, pneumati...

Abstract

The invention relates to a mobile power tool (10), more particularly a hand power tool (10) or semi-stationary power tool (10), for machining a workpiece (W), the power tool (10) having an in particular plate-type guide element (30) with a guide surface (32) for guiding the power tool (10) on the workpiece (W), or for guiding the workpiece (W) on the power tool (10). The power tool (10) has: a drive unit (11) comprising a drive motor (13) for driving a tool holder (14) that is located on the drive unit (11), wherein the drive unit (11) is moveably mounted on the guide element (30) by means ofa bearing arrangement (35) for adjusting at least two actuating positions (S0, S1, S2) of the tool receptacle (14) relative to the guide surface (32) in which a working tool (15) arranged on the toolholder (14), in particular a separating tool, penetrates into the workpiece (W) at different penetration depths, in particular cuts into the workpiece (W). According to the invention, the power tool (10) comprises a height measuring device (95) for recognising a height (H) of the workpiece (W), wherein the height corresponds to a distance between a workpiece upper side (WO) provided for penetrating the working tool (15) and a workpiece (W) lower side (WU) which is opposite the workpiece upper side (WO).

Description

technical field [0001] The invention relates to a machine tool, ie a hand-held machine tool or a semi-stationary machine tool, for machining a workpiece, wherein the machine tool has an in particular plate-shaped guide element with a guide surface for guiding the machine tool on the workpiece Alternatively, the workpiece is guided on a machine tool, wherein the machine tool has a drive unit with a drive motor for driving a tool receptacle arranged on the drive unit, wherein the drive unit can be mounted on the guide surface in an adjustable manner relative to the guide surface by means of the bearing arrangement. At the guide element, to adjust at least two adjustment positions of the tool receptacle, in which the working tool, in particular the separating tool, arranged at the tool receptacle penetrates into the workpiece with different penetration depths, in particular cuts into into the workpiece. Background technique [0002] Such power tools are known, for example, as ...
