Abstract

The invention relates to a method and machining device for clamping and machining a control cabinet component in a machining device. The method includes the following steps: Arranging a workpiece configured as a control cabinet component on a work surface of a machining device; clamping the workpiece on the work surface, wherein a supporting unit with at least one clamping device arranged on it, is shifted to an edge of the workpiece using an actuator-driven shifting unit and a clamping element of the at least one clamping device is shifted from a released position to a clamped position when guided towards the edge of the workpiece, meaning that the clamping element comes to rest at multiple contact points on the workpiece so that the clamping element secures the workpiece in a machining position, preventing it from shifting perpendicularly to the work surface, and machining the workpiece using a machining tool.

First claim

The invention claimed is:

1. A method for clamping and machining a control cabinet component in a machining device, the method comprising:
arranging a workpiece configured as a control cabinet component on a work surface of a machining device,
clamping the workpiece on the work surface, wherein
a mounting rail, with at least one clamping device arranged on it, is shifted toward an edge of the workpiece, and
a clamping element of the at least one clamping device is shifted from a released position to a clamped position when guided towards the edge of the workpiece, and
machining the workpiece using a machining tool,
wherein
the mounting rail with the at least one clamping device is shifted to the clamped position at the edge of the workpiece using an actuator-driven first shifting unit,
additionally to moving the mounting rail, the clamping element is further driven along a linear axis against the edge of the workpiece by a second shifting unit,
in the clamped position, the clamping element comes to rest at multiple contact points on the workpiece so that the clamping element secures the workpiece in a machining position, preventing it from shifting perpendicularly to the work surface, and
the clamping element is swivel mounted on a pivotal axis and, when the workpiece is clamped to the work surface, a proximal and a distal section of the clamping element, which are formed on opposite sides of a segment cutout of the clamping element, come to rest on the workpiece in such a way that
the edge of the workpiece initially comes to rest in the clamping element's proximal section and
the clamping element swivels into the clamped position against the edge of the workpiece, with the clamping element's distal section coming to rest on the workpiece, in addition to the proximal section.

2. The method according to claim 1 , wherein the clamping element presses the workpiece against the work surface in the clamped position.

3. The method according to claim 1 , wherein the mounting rail with the at least one clamping device is shifted vertically using the first shifting unit.

4. The method according to claim 1 , wherein multiple clamping devices are arranged on the mounting rail where the clamping element is shifted from the released position to the clamped position when the workpiece is being clamped.

5. The method according to claim 1 , wherein the clamping element independently moves itself back to the released position when the at least one clamping device is removed from the workpiece to release it.

6. The method according to claim 1 , wherein contact areas between the workpiece's neighboring edges are formed in the clamped position.

7. The method according to claim 1 , wherein a mounting position of the at least one clamping device on the supporting unit is adjustable.

8. The method according to claim 1 , wherein the workpiece is arranged and clamped on an upright work surface.

9. The method according to claim 1 , wherein the machining device is on a floor space and wherein the first shifting unit is at a height of at least 200 cm above the floor space.

10. The method according to claim 1 , wherein the first shifting unit is operated using a pneumatic actuator.
