Abstract

A portable machine tool, in particular a hand-held planing machine, includes at least one workpiece positioning unit and at least one insert tool unit. The at least one workpiece positioning unit has at least one workpiece positioning surface. The at least one insert tool unit projects at least partially over the at least one workpiece positioning surface in order to permit processing of workpiece. The portable machine tool further includes at least one adjustment unit that is configured, in at least one state, to set at least one orientation of one or more of the insert tool unit and the workpiece positioning surface relative to one another.

First claim

1 . A portable power tool, comprising:
at least one workpiece contact unit having at least one workpiece contact surface; at least one insert tool unit that projects at least partially over the at least one workpiece contact surface in order to perform work on a workpiece; and at least one adjustment unit configured, in at least one state, to adjust at least one alignment of one or more of the insert tool unit and the at least one workpiece contact surface relative to each other.

2 . The portable power tool as claimed in claim 1 , wherein at least a parallelity between the insert tool unit and the at least one workpiece contact surface is configured to be adjusted, in at least one state, by the adjustment unit.

3 . The portable power tool as claimed in claim 1 , wherein the adjustment unit has at least one setting unit configured to set a position of an insert tool bearing element of the insert tool unit in order to adjust the alignment.

4 . The portable power tool as claimed in claim 3 , wherein the setting unit is configured as a cam mechanism.

5 . The portable power tool as claimed in claim 3 , wherein the setting unit has at least one eccentric element configured to set the position of the insert tool bearing element.

6 . The portable power tool as claimed in claim 5 , wherein the eccentric element has at least one actuation region disposed on the eccentric element symmetrically in relation to a movement axis of the eccentric element.

7 . The portable power tool as claimed in claim 5 , wherein the eccentric element has at least one fixing element receiving region, configured to receive a fixing element of the adjustment unit that is configured to fix the eccentric element in at least one position.

8 . The portable power tool as claimed in claim 1 , wherein the at least one workpiece contact surface is mounted in a movable manner, and the adjustment unit has at least one guide unit configured to limit to one a number of degrees of freedom of movement of the at least one movably mounted workpiece contact surface of the workpiece contact unit.

9 . The portable power tool as claimed in claim 8 , wherein the guide unit comprises at least one anti-rotation element configured to secure at least the at least one movably mounted workpiece contact surface of the workpiece contact unit against rotation about at least one movement axis of the workpiece contact unit.

10 . The portable power tool as claimed in claim 8 , further comprising at least one insertion depth setting unit that includes at least one insertion depth setting element, wherein the adjustment unit has at least one play avoidance element that is configured to avoid, at least substantially, a movement play of the insertion depth setting element.

11 . The portable power tool as claimed in claim 10 , wherein the play avoidance element is configured to apply at least a clamping force to the insertion depth setting element, along a that is at least substantially transverse to a movement axis of the insertion depth setting element.

12 . The portable power tool as claimed in claim 1 , wherein the adjustment unit comprises at least one surface position adjusting unit that, in order to adjust the at least one movably mounted workpiece contact surface, comprises at least one insertion depth operating element and at least one rotary disk element, which that are mounted so as to be movable relative to each other in at least one state.

13 . The portable power tool as claimed in claim 1 , further comprising at least one insert tool contact protection unit that has at least one contact protection element disposed on the adjustment unit.

14 . A method for adjusting an alignment of an insert tool unit of a portable power tool, the portable power tool including at least one workpiece contact unit that has at least one workpiece contact surface, the insert tool unit projecting at least partially over the workpiece contact surface in order to perform work on a work piece, the method comprising:
adjusting, in at least one state, at least one alignment of the insert tool unit relative to the workpiece contact surface via an adjusting unit.

15 . A method for adjusting an alignment of at least one workpiece contact surface of a workpiece contact unit of a portable power tool, the portable power tool including at least one insert tool unit that projects at least partially over the at least one workpiece contact surface in order to perform work on a workpiece, the method comprising:
adjusting, in at least one state, at least one alignment of the workpiece contact surface relative to the insert tool unit via an adjusting unit.

16 . The portable power tool as claimed in claim 1 , wherein the portable power tool is configured as a hand-held power planer.
