Abstract

The non-fixed cathode electrolytic machining device comprises an anode clamping mechanism used for clamping a cartridge receiver and a cathode machining mechanism used for stretching into the inner side of the cartridge receiver, the cathode machining mechanism comprises a cathode cutter, a flow guide part and a first sealing ring, and the flow guide part is arranged around the periphery of the cathode cutter; the flow guide part is used for abutting against the inner surface of the machine box and enabling an electrolytic machining space to be formed between the machine box and the end face of the cathode cutter, one of the cathode cutter and the flow guide part is provided with a feeding groove, and the other one of the cathode cutter and the flow guide part is provided with a limiting flange clamped in the feeding groove. The feeding groove extends in the feeding direction of the cathode cutter to form a feeding space for the limiting flange to move, and the first sealing ring is pressed in the feeding space in an elastic mode. According to the non-fixed cathode electrolytic machining device, the cathode cutter can move relative to the flow guide part to achieve feeding, the stray corrosion phenomenon during electrolytic machining is reduced, and the machining precision of a casing cavity is improved.

Description

technical field [0001] The invention relates to the technical field of electrolytic machining, in particular to a non-fixed cathode electrolytic machining device. Background technique [0002] At present, for the processing of the cavity on the inner surface of the casing of the aero-engine, the machining method is usually adopted, firstly shape the shape by stamping, and then remove the allowance by turning. It is easy to cause deformation of the casing and reduce machining accuracy. [0003] In this regard, electrolytic machining is a special processing technology based on the principle of electrochemical anodic dissolution to remove material from the workpiece. The cavity is formed at one time, no follow-up process modification is required, and the processing efficiency is high. However, since the cavity to be processed on the casing is located inside the casing, it is difficult to feed the cathode cutter, so the fixed cathode processing method is usually used, that is,...
