Abstract

The invention discloses a combined machining testing device of spark electrolysis discharging, applied to a semicircle orifice. The device comprises a testable base, wherein a guide rail platform is disposed on the testable base; an electric main shaft clamp is in slide connection to a side edge of the guide rail platform; a high-speed electric main shaft is installed in the electric main shaft clamp; an electric main shaft clamping head is installed on the bottom of the high-speed electric main shaft; a tool electrode is clamped by the electric main shaft clamping head; a to-be-processed workpiece and a prefabricated mold which are adhered mutually are clamped inside a box body structure of an electrolytic bath; a micro lead screw vertically passes through a channel in which a semicircleguide hole of the prefabricated mold is located; a semicircle servo plate is disposed on the top of the micro lead screw; and the semicircle servo plate is in clearance fitting inside the semicirclecolumnar guide hole. In the device, the micro lead screw which is driven by a second servo motor drives the semicircle servo plate to make axial feeding; synchronous and homodromous constant-speed feeding is realized between the micro lead screw and the high-speed electric main shaft; and intermittent feeding defects are not generated during transmission of the micro lead screw, so actual transmission accuracy is increased.

Description

Technical field [0001] The invention belongs to the technical field of precision and special processing, and specifically relates to an electric spark electrolytic discharge composite machining test device for semicircular holes. Background technique [0002] EDM is a precision special machining process that combines EDM and EDM, also known as electrochemical discharge machining. It can process both metallic materials and non-metallic materials. With the continuous development of the aerospace industry, automobile industry, medical device industry, and micro-electromechanical systems, in some special cases, it is necessary to process semi-circular hole microstructures on some specific parts. Generally, the EDM EDM test bench can only machine a complete round hole, and it is difficult to machine a semicircular hole. Secondly, the traditional machining test device cannot observe and record the machining gap in real time during the EDM EDM machining process. The generation of bubb...
