Pulse current and vibration matched feeding device

Abstract

The invention discloses a pulse current and vibration matched feeding device which comprises a housing, and a cam and a sliding block that are arranged in the housing; the upper part of the cam is connected with a motor; a groove is formed in the upper part of the sliding block; the lower part of the cam is movably sleeved in the groove in the upper part of the sliding block; profile curves are formed in the cam; cylindrical pins are arranged on the sliding block, and are limited in the profile curves of the cam, and thus rotary motion of the cam is converted to up-down vibration of the sliding block; a permanent magnet is arranged on the sliding block; a hall switch is arranged at the place where the sliding block is in the lowest position after the sliding block vibrates downwards, in the housing; and when the sliding block is in the lowest position after the sliding block vibrates downwards, the hall switch sends out a voltage signal to a driving module, and thus a pulse power source sends out a packet high frequency pulse. An electrolytic solution in a machining gap can be renewed effectively; pulse current and vibration are matched for feeding, a cathode is vibrated to be fed to a place closest to an anode and the pulse power source sends out pulse, thus dispersion corrosion is reduced, energy consumption is reduced, and the precision of electrolytic machining is improved.

Description

technical field [0001] The invention relates to an electrolytic machining pulse current and vibration matching feeding device and method used in the field of non-traditional machining, and is mainly used for pulse current vibration feeding precision electrolytic machining. Background technique [0002] At present, the processing used in mechanical manufacturing can be divided into traditional mechanical processing and non-traditional processing. [0003] Traditional machining relies on the tool material being harder than the workpiece material, and using mechanical energy to remove excess material on the workpiece, which is generally feasible. However, when the workpiece material becomes harder and the processed surface becomes more and more complex, traditional machining will limit the productivity and affect the processing quality, and sometimes even cannot be processed; if the wall thickness of the workpiece is getting smaller and smaller (the wall thickness is less than ...

AI Technical Summary

Problems solved by technology

During the processing, the gap is filled with electrolyte, because the products dissolved in the anode of electrolytic processing are all dissolved in the electrolyte, if the electrolyte in the processing gap cannot be updated in time, the electrolytic processing cannot be carried out normally, even in small gap processing short circuit phenomenon

On the other hand, DC power electrolytic machining will produce stray corrosion, so that electrolytic machining will also occur in parts that do not need to be processed, seriously affecting the machining accuracy
