Power supply unit for electric discharge machining

Abstract

The invention relates to a power supply device for electric spark machining. The power supply device comprises a clamping bottom plate and a demounting device. A rubber pad is arranged at the top of the left end of the clamping bottom plate. The demounting device is mounted at the top of the left end of the clamping bottom plate. The demounting device comprises a demounting motor, a demounting rotating shaft, a demounting rotating plate, a demounting vertical plate, a demounting limiting plate, a telescopic mechanism, four demounting mechanisms and fixing mechanisms. The telescopic mechanism comprises demounting telescopic rods, demounting springs, a demounting connecting plate, demounting pushing rods, a clamping hook, a clamping hook spring, a pushing push rod, a spring connecting plate,a demounting fixing plate and a clamping hook lug seat. According to the power supply device, the difficult problems that when a power supply protective cover of an existing electric spark machine tool is cleared, demounting of the power supply protective cover is tedious, demounted bolts are prone to being lost, and the power supply protective cover cannot be fixed when cleared and is prone to dislocation when mounted can be solved.

Description

technical field [0001] The invention relates to the technical field of electric discharge machine tool processing, in particular to a power supply device for electric discharge processing. Background technique [0002] EDM machine tool is a kind of machine tool equipment that uses the principle of electric spark discharge to erode metal surfaces to process metal parts; because the principle of EDM is different from that of ordinary metal cutting, EDM machine tools are similar to ordinary metal cutting machine tools. are different in structure. First of all, it has a high-energy pulse power supply device to provide energy for generating electric sparks. The main function is to generate repeated high-intensity electric pulses on tool electrodes and workpiece electrodes to generate discharge electric sparks; pulse control of EDM machine tools It is carried out by pulse power supply. The pulse power supply is installed on the outside of the EDM machine tool. When the pulse powe...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the above-mentioned problems, the present invention provides a power supply device for electric discharge machining, which can solve the problems of cumbersome disassembly of the power supply protection cover existing in the cleaning of the power supply protection cover of the electric discharge machine tool, easy loss of disassembled bolts, and inability to clean the power supply protection cover. It is easy to dislocation when installing the power supply protection cover; it can realize the removal and installation of the protection cover for the power supply of the EDM machine tool, and the function of firmly supporting the protection cover when cleaning. It will not be lost, the power supply cover can be fixed when it is cleaned, and the power supply cover will not be misplaced when it is installed, etc.
