Please refer to Figures 1-4 The embodiment provides a polishing device for mechanical accessories, which can effectively reduce deviation and improve work efficiency. The body 1 is provided with a polishing mechanism 2, and the polishing mechanism 2 comprises a polishing disc 21 and a power assembly 22 for driving the polishing disc 21 to move downward and rotate. The power assembly 22 comprises an air cylinder 221 arranged in the body 1, and the telescopic end of the air cylinder 221 is provided with a mounting sleeve. The inside of the mounting sleeve is provided with a motor 222, and the output end of the motor 222 is provided with a rotating shaft 223 mounted on the polishing disc 21. When the bottom of the polishing disc 21 contacts the top of the mechanical accessory, the motor 222 is started, and the polishing disc 21 is driven to rotate by the rotating shaft 223 to polish the accessory.

[0022] Further, as Figures 1-4As shown, the retaining assembly 23 includes two clamps 231 symmetrically arranged on the top of the polishing table 11, the outer wall of the mounting sleeve is provided with a connecting frame 232 surrounding the polishing table 11, two movable plates 233 are symmetrically hinged below the polishing table 11, one end of the two movable plates 233 is hinged with two push-pull plates 234 in sliding connection with the polishing table 11, and the two clamps 231 are respectively arranged on the top of the two push-pull plates 234. The shape of the two clamps 231 is selected as an arc shape, and the arc design of the clamp 231 is replaceable, thereby increasing the application range of the equipment, especially when processing mechanical parts of different shapes, the work efficiency can be improved. And the opposite sides of the two clamps 231 are adhesively provided with protective pads, and the material of the protective pad is selected as rubber material. Place the precision mechanical parts of a certain size on the top of the polishing table 11, start the cylinder 221 to drive the polishing disc 21 to move down until the bottom of the polishing disc 21 contacts the top of the mechanical part, the cylinder 221 as a power source can accurately control the descending speed of the polishing disc 21, ensure the precision in the polishing process, and can avoid uneven polishing or damage to the parts due to excessive or insufficient force. At the same time, the two connecting frames 232 are synchronously lowered to make the two movable plates 233 move and pull the two push-pull plates 234 to move, the outer walls of the two push-pull plates 234 are provided with limiting blocks, two slide ways are formed in the inner wall of the polishing table 11 for the two push-pull plates 234 to slide, and limiting grooves are formed in the inner walls of the two slide ways for the limiting blocks to slide. The two clamps 231 fix the precision mechanical parts of a certain size on both sides while the bottom of the polishing disc 21 contacts the top of the mechanical part, which can ensure the parallelism and synchronism of the clamps 231, thereby ensuring that the precision mechanical parts can be stably clamped, and the synchronous work of the connecting frame 232, the movable plate 233 and the push-pull plate 234 can effectively reduce the deviation and ensure the stability and consistency of the part clamping. And the opposite sides of the two clamps 231 are adhesively provided with protective pads, and the material of the protective pad is selected as rubber and other soft materials, which has a certain compression space during clamping to ensure the normal operation of the polishing work, and the design of the protective pad can effectively protect the surface of the precision parts from being damaged, especially for parts with surfaces prone to scratching or wear, the use of rubber and other soft materials can provide sufficient buffering effect and reduce the pressure marks or scratches caused by clamping.

[0023] Further, as Figures 1-2As shown, the protection assembly 24 includes a protective cover 241 arranged outside the polishing disc 21, the inside of the protective cover 241 is sleeved with a sleeve 242, the inner wall of the protective cover 241 is provided with a sliding block, the outer wall of the sleeve 242 is vertically provided with a sliding groove for the sliding block to slide, the sleeve 242 rotates on the outer wall of the rotating shaft 223, and the bottom of the protective cover 241 is provided with a sealing and limiting assembly 243. The sealing and limiting assembly 243 includes a sealing clamping block 2431 arranged at the bottom of the protective cover 241, and the top of the polishing table 11 is provided with a sealing groove 2432 fixed and detachable with the sealing clamping block 2431. Before the protective cover 241 moves downward, the sealing clamping block 2431 at the bottom of the protective cover 241 is manually aligned with the sealing groove 2432, and the telescopic end of the air cylinder 221 drives the polishing disc 21 to move downward, at the same time, the protective cover 241 first contacts the top of the polishing table 11, and the sealing clamping block 2431 at the bottom of the protective cover 241 is clamped into the sealing groove 2432 to form a sealed polishing working area and form a positioning and anti-rotation limiting for the protective cover 241. The protective cover 241 provides a closed environment during polishing, and the sealing ensures that the dust and impurities generated during polishing will not splash out, reducing the pollution to the surrounding environment, and improving the cleanliness and safety of the working place. The telescopic end of the air cylinder 221 continuously drives the polishing disc 21 to move downward, and the protective cover 241 slides in the sliding groove through the sliding block. The design of the sliding block and the sliding groove enables the protective cover 241 to be flexibly adjusted according to the downward movement of the polishing disc 21, and always maintains the closed protection of the polishing process. The polishing disc 21 rotates to polish the accessory. The protective cover 241 plays a protective role during polishing to prevent impurities generated during polishing from splashing out and keep the surrounding environment clean. Especially during high-precision polishing, impurities are prevented from splashing outside, reducing potential safety hazards. In addition, it can also reduce the influence of dust on the operator during polishing, and improve the safety and comfort of the working environment.
