When starting work, the workpiece is placed on the clamping structure 3 by the manipulator, the motor in the transmission part 1 runs to drive the gear part 2 to operate, and the gear part 2 drives the clamping structure 3 to rotate.
[0023] like Figure 2 As shown, the gear part 2 includes a rotating disk 23, and an inner half tooth 231 is provided in a half area of the inner wall of the rotating disk 23. A cylindrical central axis 232 is provided at the center of the rotating disk 23, and an outer half tooth (not marked in the figure) is provided on the outer wall of the central axis 232 in an area opposite to the position of the inner half tooth 231 of the rotating disk 23. For ease of understanding, the area where the inner half tooth 231 and the outer half tooth are located is further described in detail, specifically:
[0024] Continue Figure 2 As shown in , the outer circumference of the rotating disk 23 is limited to 360°, and the 0°-360° rotation direction is counterclockwise (as shown by the arrow in the figure), and the 0°-180° of the rotating disk 23 is the area where the inner half teeth 231 are located, and the 180°-360° is the area where the outer half teeth are located;
[0025] The central axis 232 is fixedly connected to the transmission part 1, and a fixed axis (not shown) is arranged inside the central axis 232. A gear 22 is arranged in the turntable 23, and the gear 22 is meshed with the inner half teeth 231, and the gear 22 is meshed with the outer half teeth.
[0026] When starting to work, the motor of the transmission part 1 drives the central shaft 232 to rotate counterclockwise. When the outer half teeth are meshed with the gear 22, the gear 22 rotates clockwise. When the gear 22 is meshed with the inner half teeth 231, the gear 22 rotates counterclockwise.
[0027] like Figure 3 and Figure 4 As shown, the clamping structure 3 includes a rotating disk 31, the center of the rotating disk 31 is fixedly connected to the central axis 232, the rotating disk 31 is provided with four groups of centrally symmetrical limiting grooves 33, the limiting grooves 33 are arc-shaped grooves, a cover plate 36 is installed on the rotating disk 31, the cover plate 36 is fixedly connected to the fixed axis, the cover plate 36 is provided with a groove corresponding to the position of the limiting groove 33 (marked in the figure), a sliding rod 35 is installed in the groove, the sliding rod 35 is slidably connected in the groove, a chuck 34 is provided on the sliding rod 35, the sliding rod 35 is rotatably connected to the chuck 34, a sliding groove 351 is provided on the sliding rod 35, and a spring (not marked in the figure) is provided inside the sliding groove 351, specifically:
[0028] The cooperation between the sliding groove 351 and the spring enables the sliding rod 35 to perform a linear contraction movement;
[0029] A limiting block 32 is provided at the connection between the sliding rod 35 and the limiting groove 33 below, and the limiting block 32 is slidably connected to the limiting groove 33 along its inner wall. The chuck 34 includes a connecting frame 344, and the connecting frame 344 is V-shaped.

When the rotating disk 31 rotates clockwise, the cover plate 36 is fixed, and the limiting groove 33 drives the limiting block 32 to make the sliding rod 35 slide linearly outward along the inner groove of the cover plate 36, and push out the clamp 34 until the abutting wheel 343 contacts the inner wall of the notebook computer shell. The torsion spring 342 corrects the position of the clamp 34 and the inner wall of the notebook computer shell and provides a clamping force. The gear part 2 continues to move, and the sliding groove 351 on the sliding rod 35 cooperates with the spring to tighten, so that the clamping structure 3 is in the gear part. 2 is continuously moved to protect the structure from being damaged, and a clamping force is provided by a clamp 34 on the inner wall of the laptop computer shell, so that the clamping effect is better. At the same time, this cooperation also enables the clamping structure 3 to clamp rectangular laptop computer shells of different sizes and shapes. When the gear 22 in the gear part 2 moves counterclockwise, the limit groove 33 drives the limit block 32 to make the sliding rod 35 slide linearly inward along the inner groove of the cover plate 36, pulling the clamp 34, and the torsion spring 342 and the spring in the sliding rod 35 return to their original state, and the clamping is completed.
[0030] In summary, the intermittent adjustment of the rotation direction of the gear 22 is achieved through the coordinated movement of the gear 22 in the motor-driven gear part 2 and the turntable 23 with two sets of relative half teeth. In this process, the rotation of the gear 22 drives the clamping structure 3 to clamp the laptop computer shell, and the clamping structure 3 performs expansion clamping on the outer and inner walls of the laptop computer workpiece, which does not affect the polishing of the outer wall of the laptop computer. The sliding rod 35 in the clamping structure 3 is provided with a sliding groove 351, and a spring is provided inside it, so that the sliding rod 35 is retractable to cope with rectangular laptop computer shells of different sizes, and protect the structure from damage during continuous clamping movement. The cooperation between the limit groove 33 and the limit block 32 enables the clamping structure 3 to extend the sliding rod 35 outward by rotation to achieve clamping of the laptop computer shell.

All technical solutions under this idea belong to the protection scope of the present application. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present application should also be regarded as the protection scope of the present application.
