Electrolytic machining tool capable of achieving machining gap balance

Abstract

The invention relates to an electrolytic machining tool capable of realizing machining gap balance, which comprises a workbench arranged in an electrolytic tank and further comprises a cathode, the cathode is of a hollow structure, and the machining gap between the machining end of the cathode and a workpiece is dynamically balanced through a gap balance mechanism. The whole gap balance mechanism is arranged in the vertical direction and comprises a driving mechanism, a connecting rod displacement amplifying mechanism and a cathode mechanism, and a cathode is connected with the cathode mechanism. The driving mechanism drives the cathode connected with the cathode mechanism to move in the vertical direction through the connecting rod displacement amplifying mechanism so as to adjust the machining gap between the cathode and the workpiece. According to the technical scheme, dynamic balance of the machining gap can be achieved in the machining process, the problem that the workpiece machining quality is poor due to the fact that the machining gap is unstable is solved, and the workpiece machining precision is improved.

Description

technical field [0001] The invention relates to the field of electrolytic machining, in particular to an electrolytic machining tool capable of realizing machining gap balance. Background technique [0002] With the rapid development of the machinery manufacturing industry, a large number of high-strength, high-hardness hard-to-machine alloy materials have become more and more widely used, and the requirements for the machining accuracy and surface quality of parts are also getting higher and higher. And instruments and other fields, the application of these difficult-to-machine materials is more and more extensive. [0003] At present, these difficult-to-machine materials are generally processed by mechanical cutting, laser, EDM and other methods, but traditional machining has thermal deformation, while laser machining and EDM will generate defects such as recast layers and microcracks. Electrolytic machining technology is a non-contact machining method that uses the princ...

AI Technical Summary

Problems solved by technology

If the processing gap is too small, as the processing depth increases, it will become more and more difficult to discharge the electrolytic products, which will cause product accumulation and lead to short circuit

If the machining gap is too large, although the electrolysis product is easier to discharge, it will affect the shape accuracy and surface quality of the workpiece, making the machining effect poor

The current electrolytic machining equipment cannot guarantee the balance of the gap during the machining process, and the machining quality of the workpiece is often poor due to the instability of the machining gap. Therefore, there is an urgent need for an electrolytic machining tool that can achieve a balanced machining gap
