Processing method of baseplate bunching groove for electric pulse processing

Abstract

The invention discloses a processing method of a baseplate bunching groove for electric pulse processing and belongs to the technical field of processing aero-engine parts. The processing method includes the steps: placing a to-be-processed baseplate on a table top of a working table of a slow-wire-feeding machine tool in a laterally-standing manner, determining a clamping position, clamping the baseplate on the tablet top of the working table, and enabling an alignment reference surface of the baseplate to be perpendicular to the table top of the working table; pressing down a starting button of a machine tool control panel, entering an operation interface, and importing a graphic file which is well drawn in advance into an operation system; performing simulation running on a running program in the operation system; connecting a molybdenum wire for processing onto the machine tool, switching on a power source switch of the machine tool, and determining a processing starting point; closing a retaining plate of the working table, pressing down a water injection button, pressing down a processing button when distilled water fully covers the surface of the baseplate, enabling the machine tool to start to execute the running program and perform cutting processing on the baseplate; after execution of the running program is completed, pressing down a water draining button to discharge the distilled water, opening the retaining plate of the working table, and demounting the processed baseplate.

Description

technical field [0001] The invention belongs to the technical field of aero-engine parts processing, in particular to a processing method for grouped grooves of a bottom plate for electric pulse processing. Background technique [0002] For aero-engines, the manufacturing accuracy of its parts directly determines the performance of the aero-engine, and is related to the safety of pilots. How to improve the manufacturing accuracy of aero-engine parts has become the constant pursuit of those skilled in the art. Target. [0003] Although the various components that make up the aero-engine have different structures, most of the components must have a hole structure. For these components that need to be processed, the traditional method usually uses drilling, and most of the drilling is single. Hole drilling leads to very low processing efficiency.

[0003] Although the various components that make up the aero-engine have different structures, most of the components must have a hole structure. For these components that need to be processed, the traditional method usually uses drilling, and most of the drilling is single. Hole drilling leads to very low processing efficiency. In order to solve the problem of low efficiency, related technical personnel try to use electric pulse processing to process holes in batches of parts. In order to achieve the purpose of processing batches of parts at one time, related technologies The personnel designed a special fixture for this purpose. As an important part of the fixture, the bottom plate, its manufacturing accuracy directly determines the clamping accuracy of the part, which in turn affects the machining accuracy of the part

[0004] The bottom plate is designed with groups of parts installation grooves, these groups of parts installation grooves are formed by a number of protrusions at intervals, the parts installation grooves are required to be straight grooves, and the groove width tolerance between the groove walls on both sides of the groove is required to be ±0.01 mm, in the past, the mounting grooves of such parts were processed by CNC milling first, and then manual clamping or flat grinding and finishing, but the size was often out of tolerance, and the final tolerance requirements could not be met. In the end, it could only be repaired continuously. To meet the tolerance requirements, this traditional processing method is not only difficult to process, but also has low processing accuracy and low pass rate of finished products, which cannot well meet the needs of actual production
