An oil tank sealing door panel device for large electric discharge machine tools

Abstract

The invention discloses an oil groove sealing door plate device for a large-size electric discharge machine. The oil groove sealing door plate device for the large-size electric discharge machine comprises a power system, a transmission system, an actuating system and a control system, wherein the power system comprises a motor; the transmission system comprises a transmission mechanism, a transmission shaft, a steel wire rope winch, a steel wire rope and a fixed pulley; the actuating system comprises a guide groove, a guide wheel, a door plate, a door plate buckle wedge-shaped structure and a machine base buckle wedge-shaped structure; the control system comprises a limit switch and a change-over switch. The power system drives the transmission system to enable the door plate to move, the door plate is tightly attached to an oil groove plate through the guide groove and the buckle wedge-shaped structures on the upper portion and the lower portion, a sealing strip on the door plate is located at a compressed state, an oil groove of the electric discharge machine can be sealed mechanically and automatically, and the sealing effect is better. In addition, the limit switch is used for detecting the movement position of the door plate, and the limiting position of the door plate is automatically limited.

Description

technical field [0001] The invention relates to a large electric discharge machine tool oil tank sealing door panel device, in particular to a bull head type large electric discharge machine tool automatic sealing oil tank door panel device, which belongs to the innovative technology of the electric discharge machine tool sealing door panel. Background technique [0002] In the working condition of the EDM machine tool, due to the large current between the electrode and the workpiece, the electrode will generate an electric spark at the moment of discharge. If a workpiece is machined without coolant coverage, it will create safety concerns. Therefore, if the surface where the workpiece interacts with the electrode can be immersed under the oil surface, the spark will be controlled, but this oil groove is not needed when loading and unloading the workpiece. Therefore need a door panel 9 device that is easy to operate and matches with workbench 12 and has automatic sealing fu...

AI Technical Summary

Problems solved by technology

These sealed door panels 9 are mostly due to the limitation of the movement mode of the door panels 9. For long-span (more than 4 meters) door panels 9, it is difficult to drive both ends at the same time, and it is not easy to achieve self-locking sealing.

Therefore, it is only suitable for manual sealing of small machine tool door panels.
