The clamping assembly 32 comprises at least one clamping cylinder 321, and the head of the clamping cylinder 321 is close to or far away from the fixing structure 31, so that the clamping assembly 31 is clamped or far away from the fixing structure 31, and the fixing and the dismounting of the fixing structure 31 are facilitated. The part to be polished is fixed on the fixing structure 31, and the polishing mechanism 40 is driven by the mechanical arm mechanism 20 to move close to or away from the fixing structure 31, so as to polish the part to be polished. In this embodiment, the fixing structure 31 is a rod penetrating jig, and the fixing structure 31 penetrates through the part to be polished to fix the polished part.

Further, the clamping assembly 32 further includes a rotating shaft 322 and a sliding ejector rod 323 coaxially disposed with the rotating shaft 322 and accommodated in the rotating shaft 322, wherein the sliding ejector rod 323 and the rotating shaft 322 rotate synchronously. One end of the sliding ejector 323 abuts against the clamping cylinder 321, and the other end is connected with the fixing structure 40 in a clamping manner. The rotating shaft 322 rotates to drive the sliding ejector rod 323 to rotate, and the fixing structure 31 is driven by the ejector rod 323 to synchronously rotate, so that the part to be polished fixed on the fixing structure 31 is turned over.

Referring to fig. 4, the sliding rod 323 includes a rod body 3231 and a ball 3232, and the ball 3232 is clamped between the rod 3231 and the clamping cylinder 321 for separating the rotation of the rotating shaft 322 and the clamping cylinder 321, so as to effectively protect the service life of the clamping cylinder 321.

In this embodiment, the number of the clamping assemblies 32 is two and the two clamping assemblies are oppositely arranged at intervals. One end of the ejector rod 3231, which is away from the ball 3232, protrudes to form a truncated cone-shaped fixture block 3233, a fixture hole 311 corresponding to the fixture block 3233 is formed in the surface of the fixing structure 321, which is opposite to the fixing structure 321, and each fixture block 3233 is held and accommodated in the corresponding fixture hole 311. The clamping cylinders 321 of the two clamping assemblies 32 extend and contract to clamp and separate the fixed structure 31. The two ends of the fixed structure 31 are respectively clamped and fixed by the two clamping components 32, so that the fixed structure 31 is more firmly fixed on one hand, and the fixed structure 31 is convenient to detach on the other hand.

Two ends of the spring 324 abut against the step 3223 and the step 3236, respectively, and the spring 324 is in a compressed state. Due to the arrangement of the spring 324, when the clamping cylinder 321 is far away from the fixed structure 31, the rod body 3231 can be automatically far away from the fixed structure 31 under the elastic action of the spring 324, so that the fixed structure 31 can be conveniently detached and installed.
