Device and method for processing inclined surface through follow-up sealing liquid cutting-in type electrolytic milling machining

Abstract

The invention relates to a device and method for processing an inclined surface through follow-up sealing liquid cutting-in type electrolytic milling machining, and belongs to the field of electrolytic processing technology. The device mainly comprises a tool cathode, an upper supporting plate, guide rods, a spring, a linear bearing, a universal ball and a water blocking block. The upper supporting plate is fixed on the front of the tool cathode; the two guide rods are fastened on the upper supporting plate through threads; the guide rods are sequentially sleeved with the spring and the waterblocking block, the water blocking block can slide up and down along the axis direction of the guide rod through the linear bearing, the universal ball is arranged below the water blocking block and is contact with a work piece in real time, and the universal ball is pressed on a surface of the work piece under the action of the spring compression elasticity. When the tool cathode processes the inclined surface by using a cutting-in type electrolytic machining method, the follow-up sealing liquid device can float up and down according to the up-and-down movement of the tool cathode, so as to change the cross-sectional area, out of water, of the tool cathode, the spraying of the electrolyte liquid from a liquid outlet to a processing area is limited in real time, and the processing precision, the stability and the efficiency are improved.

Description

technical field [0001] The invention relates to a device and method for cutting-in electrolytic milling inclined surfaces with a moving sealing liquid, and belongs to the technical field of electrolytic processing. Background technique [0002] With the rapid development of aerospace, weaponry and other fields, key components need to be designed as an integral structure in order to ensure accuracy and reduce assembly errors, so as to reduce weight as much as possible while ensuring performance. Materials such as high-temperature alloys and titanium alloys have light weight, high specific strength, and good corrosion resistance, and are widely used in aviation, aerospace, ships, weapons and other fields. For example, GH4169 accounts for 34% of the total weight of the CF6 engine, and titanium alloy accounts for 41% of the total weight of the materials used in the fighter F22 developed by my country's fourth-generation self-organization. Due to the complex shape of these large...

Problems solved by technology

However, during the plunge-type electrolytic machining of inclined surfaces, due to the movement of the tool electrode, part of the electrolyte sprayed out of the liquid outlet is sprayed out of the processing area, which not only reduces the electrolyte in the processing area, but also easily causes processing disorder and aggravates abnormal Stray corrosion in the processing area, so how to promote the stable flow of electrolyte to the processing area during electrolytic milling has become a key problem that needs to be solved urgently.
