[0037] In one embodiment, referring to Figures 1 to 2 as shown, a polishing machine tool for a computer middle frame provided by the present invention includes: a bed body 1, a first moving assembly 2, a clamping module 3 and a polishing module 4.

[0038] The bed body 1 has an installation end face, and the installation end face serves as a carrier for installation.

[0039] The first moving assembly 2 is fixedly connected to the bed body 1 and has a first moving platform 21 that can move along the length direction of the bed body 1. Among them, the movement of the clamping module 3 is driven by the first moving platform 21. The clamping module 3 has a rotating unit 31 and at least two sets of clamping units 32 for clamping the computer middle frame. 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 units 32 are fixed to the rotating bracket 311 in an arc shape centered on the rotation center line of the rotating bracket 311. Among them, the rotation center line of the rotating bracket 311 is arranged along the width direction of the bed body 1; the rotating bracket 311 has several fixed end faces for installing the clamping units 32; by rotating the rotating bracket 311, the clamping units 32 at different stations can be switched.

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

[0041] Specifically, in this example, through the cooperation of the first moving assembly 2, the clamping module 3 and the polishing module 4, the polishing of the computer middle frame is realized, the polishing accuracy of the computer middle frame is ensured, and the clamping units 32 at different stations are switched by using the rotating unit 31, so that the polishing wheel 401 can polish the computer middle frames at different stations, reducing the processing path of the polishing machine tool, improving the processing efficiency of the computer middle frame, and reducing the production cost of the computer middle frame.

[0042] As an optional example, please refer to Figures 1 to 3 As shown, to ensure the position accuracy of the clamping module 3 during switching, the rotating unit 31 includes a motor base 312 and two sets of symmetrically arranged rotating bases 313. The rotating bases 313 are fixedly connected to the first moving platform 21 by means of bolt connection. The rotating bracket 311 is fixedly connected to the rotating base 313 by means of bearing connection. A driven gear 314 is fixedly mounted on the outer wall of the rotating bracket 311 by means of key connection. The motor base 312 is fixedly connected to the first moving platform 21. A rotating motor 315 is fixedly mounted on the motor base 312 by means of bolt connection. A driving gear 316 is fixedly mounted on the output shaft of the rotating motor 315 by means of key connection. A rotating shaft 317 is fixedly mounted on the motor base 312 by means of bearing connection. A rotating gear 318 is fixedly mounted on the outer wall of the rotating shaft 317 by means of key connection. The rotating gear 318 meshes with the driving gear 316 and the driven gear 314. Among them, the rotating motor 315 is a motor with a self-locking function, which can maintain the relative angle of the current rotating bracket 311 in the case of power failure.

[0043] Specifically, in this example, the operation of the rotating motor 315 drives the driving gear 316 to rotate. The driving gear 316 drives the rotation of the rotating gear 318. The rotating gear 318 drives the driven gear 314 to rotate. The driven gear 314 drives the rotating bracket 311 to rotate, 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.

[0044] As an optional example, please refer to Figures 1 to 4 As shown, to reduce the production difficulty of the rotating bracket 311, the rotating bracket 311 includes a main frame body 3111 and side connecting shafts 3112 fixed on both sides of the main frame body 3111 by means of bolt connection.

The driven gear 314 is sleeved on the side connecting shaft 3112 on one side of the main frame body 3111 by means of key connection. Among them, a fixed end face is arranged on the main frame body 3111, and the side connecting shaft 3112 is provided with a wire installation groove penetrating the side connecting shaft 3112 along the central axis direction.

[0045] Specifically, in this example, by splitting the rotating bracket 311 into the main frame body 3111 and the side connecting shafts 3112, the structural difficulty of the rotating bracket 311 is reduced, the disassembly and assembly of the rotating bracket 311 are facilitated, and the production cost of the polishing machine tool is reduced.

A clamping motor 323 is fixedly installed at one end of the clamping base 321 close to the main frame body 3111 by means of bolt connection. A positioning flange 3211 for positioning the computer middle frame is arranged at one end of the clamping base 321 far from the main frame body 3111. A clamping screw 324 is fixedly installed in the clamping base 321 by means of rotational connection. The output shaft of the clamping motor 323 is fixedly connected to the clamping screw 324. A guiding chute 3212 is formed at one end of the positioning flange 3211 facing away from the main frame body 3111. A sliding guide post 3221 matching the guiding chute 3212 is arranged at one end of the clamping and fixing block 322 facing close to the main frame body 3111. A clamping threaded hole 3222 matching the clamping screw 324 is formed at one end of the clamping and fixing block 322 facing close to the main frame body 3111. A clamping groove for clamping and fixing the computer middle frame is formed by combining the lower end of the clamping and fixing block 322, the side wall of the positioning flange 3211 and the upper end of the clamping base 321. Among them, the clamping motor 323 has a self-locking function, which can avoid the ineffective rotation of the clamping screw 324. A through clamping through hole is formed in the clamping base 321, and the clamping screw 324 is inserted into the clamping through hole by means of bearing connection.

[0047] Specifically, in this example, the clamping groove formed by combining the lower end of the clamping and fixing block 322, the side wall of the positioning flange 3211 and the upper end of the clamping base 321 is used to clamp the computer middle frame, which improves the stability of the clamping force on the computer middle frame, avoids the vibration of the computer middle frame during the polishing process, prevents defects such as water ripples on the outer wall of the computer middle frame, and ensures the polishing accuracy of the computer middle frame.

[0049] Specifically, in this example, the power supply connection component 402 provides power for each clamping unit 32, reducing the layout of the circuit, avoiding the interference of the circuit with the movement path of the polishing wheel 401, and improving the safety of the polishing machine tool.
