An electrolytic machining tool for flexible parts

Abstract

The invention relates to an electrolytic processing tool for flexible parts, which includes a base and a cover plate. The base is provided with a tank body that runs through the left and right sides of the base. The second tank body where the processing components are matched, the movement and rotation of the components to be processed in the second tank body is limited by the positioning clamping device, the left side of the base is provided with a sealing plate, and the right side of the base is provided with a fixing plate, The tank body forms a closed cavity under the cooperation of the sealing plate, the fixing plate, the cover plate and the base. The cover plate and the base are respectively equipped with an electrolyte inlet channel and an electrolyte outlet channel. The drive shaft of the vibrating feed mechanism is insulated and connected, and the drive shaft drives the electrolytic machining cathode to feed horizontally along the direction defined by the first tank body so that the cathode cutter on the electrolytic machining cathode performs electrolytic machining on the component to be processed. The invention has the advantages of wide processing range, high processing efficiency, good processing surface quality and the like.

Description

technical field [0001] The invention relates to the field of electrolytic machining, in particular to an electrolytic machining tool for flexible parts. Background technique [0002] In order to provide adequate visual feedback to the surgeon and enable dexterous tissue manipulation in modern medicine, endoscopes and other manipulable surgical instruments must have bendable and steerable sections called flexible joints. Flexible joints can be short wrists used to deflect surgical instruments, or longer sections, such as those used in continuous snake-like robots for traversing surgical anatomy. [0003] Integral fabricated flexible joints can ease the fabrication and assembly work, and continuous mechanisms with superelastic NiTi backbones and push-pull actuators belong to this category. To form a thin flexible joint with a large central lumen, casting techniques are typically used to fabricate or flex features are created on the surface of the NiTi tube by laser cutting, w...

AI Technical Summary

Problems solved by technology

Although the casting method is used to produce flexible parts, although the cost is low, the quality and precision are difficult to guarantee, and the scrap rate is also high

It is difficult to process workpieces with complex shapes by laser cutting, wire cutting or CNC manufacturing technology, and it will generate mechanical cutting force, which is prone to stress concentration and fatigue problems

Additive manufacturing technology can produce flexible parts with complex shapes and does not require traditional tools and machine tools, but there are many limitations, such as poor mechanical properties of the produced parts (low precision, more fatigue and rough surface) )
