The rotating unit 31 is fixedly connected to the first moving platform 21. The rotating unit 31 has a rotating bracket 311 that can rotate. The clamping unit 32 is fixed on the rotating bracket 311 in an arc shape with the rotating center line of the rotating bracket 311 as the center. The rotating center line of the rotating bracket 311 is set along the width direction of the bed 1; the rotating bracket 311 has a plurality of fixed end faces for installing the clamping unit 32; by rotating the rotating bracket 311, the clamping unit 32 of different stations can be switched.

[0040] The polishing module 4 is fixedly connected to the bed 1 and has a polishing wheel 401 that moves with multiple degrees of freedom. The outer wall of the computer middle frame is polished by the rotation of the polishing wheel 401.

[0041] Specifically, this example realizes the polishing of the computer middle frame through the cooperation of the first moving component 2, the clamping module 3 and the polishing module 4, thereby ensuring the polishing accuracy of the computer middle frame, and using the rotating unit 31 to switch the clamping unit 32 at different stations, so that the polishing wheel 401 can polish the computer middle frame at different stations, thereby reducing the processing path of the polishing machine, improving the processing efficiency of the computer middle frame, and reducing the production cost of the computer middle frame.

Among them, the rotating motor 315 adopts a motor with a self-locking function, which can maintain the current relative angle of the rotating bracket 311 when the power is off.

[0043] Specifically, in this example, the driving gear 316 is driven to rotate by the operation of the rotating motor 315, the driving gear 316 drives the rotating gear 318 to rotate, the rotating gear 318 drives the driven gear 314 to rotate, and the driven gear 314 drives the rotating bracket 311 to rotate, thereby realizing the position switching of the clamping module 3, ensuring the position accuracy of the clamping module 3, and improving the polishing accuracy of the computer middle frame.

[0047] Specifically, in this example, the computer middle frame is clamped by a clamping groove formed by the lower end of the clamping fixing block 322, the side wall of the positioning flange 3211 and the upper end of the clamping base 321, thereby improving the stability of the clamping force on the computer middle frame, avoiding vibration of the computer middle frame during the polishing process, causing water ripples and other defects on the outer wall of the computer middle frame, and ensuring the polishing accuracy of the computer middle frame.
