A method and device for machining process grooves

Abstract

The invention discloses a device for machining process grooves, comprising a first base plate and a second base plate. The first base plate is provided with a plurality of positioning holes, a positioning grating sheet is arranged in the positioning holes, a positioning sensor is arranged on the positioning grating sheet, and a positioning sensor is arranged on the positioning sensor. The electrode sheet positioning mechanism is set to open a through-hole slot for installing the process groove forming electrode sheet. The electrode sheet positioning mechanism is provided with a translation mechanism. The positioning sensor is connected to the input end of the controller, and the output end of the controller is connected to the digital display meter. The top of the sensor is provided with a process groove forming electrode sheet, the second base plate is used to fix the part to be processed, and the center of the part to be processed on the second base plate corresponds to the position of the positioning hole one-to-one; a set of quick-change electrodes for the main door lining are used together The collet and the grouped main door lining quick-change tooling can process multiple sets of process grooves at the same time, which greatly improves the processing efficiency; relies on the positioning grating plate and positioning sensor to ensure the correct position of the electrode plate; improves the processing position accuracy.

Description

technical field [0001] The invention belongs to the technical field of special processing, and in particular relates to a method and a device for processing a process groove. Background technique [0002] At present, the main door lining oil tank of aero-engine is mostly processed by single-station EDM machine, which is mainly processed by manually adjusting the position of the electrode sheet. The positioning and recognition accuracy of the electrode sheet is low, which seriously affects the machining position accuracy of the oil tank. The parameter control fluctuates greatly, the dimensional accuracy is not easy to control, and the forming size deviation is large. The main door lining oil tank has low processing efficiency and poor processing accuracy, and the product qualification rate is low. [0003] Faced with the development needs of new aero-engine main door linings, the problems of machining accuracy and efficiency of oil passages will become more prominent. The p...
