The number of the plurality of clamping mechanisms 40 is the same as that of the rotary table 11, each clamping mechanism 40 comprises a clamping piece 42 and at least three clamping blocks 41 (four clamping blocks 41 are preferred in the embodiment), the four clamping blocks 41 are arranged on the rotary table 11 in an annular array along the axis of the rotary table 11, the clamping blocks 41 can move along the radial direction of the rotary table 11, each clamping block 41 is provided with a clamping surface 411 and a first wedge-shaped surface 412, the clamping surfaces 411 are arranged opposite to the first wedge-shaped surfaces 412, and the first wedge-shaped surfaces 412 are inclined from top to bottom in the direction away from the axis of the rotary table 11. The abutment member 42 is vertically movable and the abutment member 42 is provided with a second wedge surface 423 cooperating with the first wedge surface 412. The clamping driving mechanism is used for driving all the abutting pieces 42 to move vertically so as to enable the clamping block 41 to perform clamping or loosening action.

In this embodiment, each rotary table 11 is designed with a clamping mechanism 40, after ceramic rods to be processed are placed in a clamping station surrounded by clamping blocks 41, the clamping driving mechanism is started to drive all the clamping pieces 42 to move downwards synchronously, in this process, the second wedge surfaces 423 on the clamping pieces 42 are matched with the first wedge surfaces 412 on each clamping block 41, so that the clamping blocks 41 are pushed to move towards the axial direction of the rotary table 11, and a plurality of ceramic rods are clamped simultaneously. After clamping, the rotation driving mechanism 20 drives all the rotating discs 11 to rotate at the same time, so as to drive all the ceramic rods to rotate. Then, the vertical polishing mechanism 30 is advanced to make the polishing surface thereof abut against all the ceramic rods at the same time, thereby polishing a plurality of ceramic rods.

After the electromagnet 52 is powered on, the magnetic attraction piece 51 is instantly attracted, so that the connecting seat 421 pulls the four abutting claws 422 to move downward at the same time, in this process, the second wedge-shaped surfaces 423 on the abutting claws 422 abut against and push the first wedge-shaped surfaces 412 on the corresponding clamping blocks 41 in the axial direction of the rotating disk 11, so that the clamping blocks 41 move in the axial direction of the rotating disk 11, the four clamping blocks 41 move close to each other at the same time, and a plurality of ceramic rods are clamped at the same time. Moreover, by designing the magnetic attraction member 51 and the connection seat 421 to be rotationally connected, when the rotation driving mechanism 20 simultaneously drives all the rotation discs 11 to rotate, so as to drive all the ceramic rods to rotate, the rotating rotation discs 11 will not affect the interference electromagnet 52.
