Abstract

A mounting device for mounting a machine tool to a floor area is provided. The mounting device includes mounting units that are attachable to the machine tool. Counter-mounting units are disposed on the floor area. The mounting device may also include electromagnets that are disposed on either the mounting units or the counter-mounting units. The machine tool can be mounted or removed by switching the electromagnets on and off. When one of the mounting units or the counter-mounting units includes the electromagnets, the other may include a ferromagnetic material.

Claims

1. A mounting device for mounting a machine tool to a floor area, the mounting device comprising:

a plurality of mounting units attachable to the machine tool;

a plurality of counter-mounting units that are disposed on the floor area;

electromagnets, that are disposed on either the plurality of mounting units or on the plurality of counter-mounting units, wherein the respective opposed mounting unit or counter-mounting unit includes a ferromagnetic material, and

a control device configured to provide a higher voltage to activate the electromagnets to mount the plurality of mounting units to the plurality of counter-mounting units and a lower voltage less than the first higher to release the electromagnet and eliminate the remanence while the lower voltage is still applied to the electromagnets.

2. The mounting device according to claim 1, wherein the plurality of mounting units are disposed along one fixing side of the machine tool, and a corner mounting unit is disposed on one corner of a releasing side of the machine tool.

3. The mounting device according to claim 2, wherein the corner counter-mounting unit has a greater extension for the releasing side.

4. The mounting device according claim 1, wherein the plurality of mounting units each include a leveling device.

5. The mounting device according to claim 4, wherein the levelling device comprises a hydraulic clamping bush.

6. The mounting device according claim 1, wherein the electromagnets are disposed on the plurality of mounting units, and the plurality of counter-mounting units cooperating with the plurality of mounting units are configured as anchor elements.

7. The mounting device according to claim 6, wherein the anchor elements comprise anchor plates.

8. The mounting device according claim 1, wherein the plurality of counter-mounting units are configured as metal plates.

9. The mounting device according to claim 8, wherein the metal plates comprise an unalloyed tool steel or a Ck45 steel.

10. The mounting device according to claim 1, wherein the plurality of counter-mounting units are disposed in a grid.

11. The mounting device according claim 1, further comprising an AC/DC converter configured to supply current or voltage to the electromagnets.

12. The mounting device according to claim 1, wherein the higher voltage is 220 volts and the lover voltage is 15 volts.

13. A machine tool comprising a mounting device according to claim 1.

14. The machine tool according to claim 13, further comprising extendable rollers for moving the machine tool, wherein the extendable rollers are provided on a base of the machine tool.

15. The machine tool according to claim 13, wherein the machine tool comprises a sheet metal processing machine.

16. The machine tool according to claim 15, wherein the sheet metal processing machine is one of a laser cutting machine, a bending machine, or a water jet cutting machine.
