A composite machining tool for electrolytic broaching for disc parts

Abstract

The invention relates to an electrolytic pusher compound machining tool for disk parts, including a working turntable, a fixture, a cathode feed assembly and a push feed assembly, the cathode feed assembly includes a cathode spline rod, an insulating rod, and a cathode installation rod and the cathode electrode, the push feed assembly includes the push spline shaft, the push gear cutter installation rod and the push gear cutter, the cathode spline rod and the push cut spline shaft are set on the machine tool base through the tool positioning support seat, and the inside of the fixture There are mutually isolated electrolyte tanks and tooth pushing chambers, the cathode electrode realizes the rough machining of the gear grooves in the electrolyte tank, and the tooth pushing cutter completes the finishing of the rough machined gear grooves in the tooth pushing chamber. It can be seen from the above technical scheme that the present invention first performs electrochemical rough machining on the gear groove, and then performs push finishing on the gear groove, which greatly reduces the material removal rate of the push processing, shortens the length of the push cutter, and prolongs the push process. The service life of the gear cutter improves the processing efficiency and reduces the production cost.

Description

technical field [0001] The invention relates to an electrolytic pushing compound processing tool for disc body parts. Background technique [0002] At present, gear processing is generally carried out in the following two ways: 1. Electrolytic gear processing: Electrolytic gear processing is a modern gear processing method that uses the electrochemical anodic dissolution of the gear blank in the electrolyte to process the tooth groove into shape. The gear after electrolytic processing There is no mechanical cutting force, residual stress, deformation and burrs on the tooth surface of the gear, but the dimensional accuracy and processing efficiency of the electrolytically machined gear are low, and the cost of single-piece and small-batch production is high. 2. Pushing gear processing: Pushing gear processing is to process the tooth surface of workpieces such as internal and external gears or racks by using a push cutter according to the forming method. The tooth shape preci...

Problems solved by technology

The tooth shape precision of the pushed tooth is high, and the roughness of the tooth surface after the pushed tooth is low, but the pushed tooth also has many disadvantages: 1) The pushed knife is processed in a form, the length of the tool is long, and the efficiency is low; 2) Each time the tool The amount of material removed is large, the wear is serious, and the service life is short; 3) Most of the pushing teeth are processed by one-time forming, and the resistance of the blade is relatively large. Most of them need to be powered by hydraulic pressure. The hydraulic equipment is bulky, complicated to manufacture, and high in cost.

[0003] With the development of the manufacturing industry, the mechanical field has higher requirements for the processing efficiency, material and structure of the workpiece, and the traditional tooth pushing processing and electrolytic processing alone cannot meet this requirement.
