[0002] With the development of processing technology, products have higher and higher requirements for processing accuracy and quality. As a traditional processing method, polishing technology is widely used in today's processing field, while mechanical polishing is mainly performed by hand. , such as special parts such as the surface of the rotary body, auxiliary tools such as turntables can be used; a potentiometer for aviation products has a polishing process in the production process, and the polishing positions are distributed on both sides of the potentiometer in the length direction and arranged symmetrically at 180° , the polishing surface is evenly distributed along the outer circle of the potentiometer at a certain arc angle, and the removal unit of polishing is very small, so the processing efficiency is low. The sliding part remains in contact and the resistivity remains consistent

[0003] At present, the equipment used for potentiometer polishing is relatively simple, rough, and all actions are manually operated, and the structure of the equipment is unstable, which makes it difficult to grasp the quality of the product, and the labor intensity of the workers during the polishing process is high. The polishing equipment for the potentiometer is A motor drives the polishing wheel to rotate at a high speed, and the polishing arc is realized by manually shaking the rocker arm with the left hand to rotate the potentiometer, and the length of the polishing is realized by rotating the screw rod with the right hand to drive the tooling of the potentiometer to move laterally, because the polishing wheel wears faster , Grinding two potentiometers needs to consume a polishing wheel, so the radial feed is also taken into account during the polishing process, and the radial feed is also realized by turning the screw rod by hand. To sum up, three hands are required to perform well To complete a polishing process, one person will not be able to feed radially in real time because both hands shake the tooling movement of the potentiometer at the same time, resulting in uneven cutting amount during the polishing process of the potentiometer, because the circular shape of the product is completed by shaking the tooling by hand Arc motion and reciprocating motion cannot meet the requirements of uniform speed and consistent polishing angle, so it is necessary to redesign a new equipment to solve the problems encountered by the existing equipment in the polishing process, ensure the production quality of products, and reduce workers.
