[0045] Overall working process:

[0046] The stepping motor 9 starts, driving the screw rod 11 to rotate on the mounting shell 10. The rotation of the screw rod 11 causes the threaded block 12 to move along the slide rail 13, and the threaded block 12 drives the moving seat 14 to move. The positioning seat 15 on the moving seat 14 fixes the template 16, and the watch case to be processed is placed in the multi-station watch case groove 17 on the template 16. When the watch case moves to the grinding position, the air cylinder 3 starts, pushing the mounting plate 4 to move downward along the guide rail 5. The grinding motor 6 below the mounting plate 4 drives the mounting disc 7 and the grinding disc 8 to rotate, grinding the watch case on the template 16. After grinding is completed, the air cylinder 3 retracts, driving the grinding disc 8 to rise. The stepping motor 9 starts again, moving the next watch case to be processed to the grinding position, repeating the above process.

[0048] As Figure 3 shown, in some embodiments, a slide rail 13 is provided on the side of the mounting shell 10, and the threaded block 12 is simultaneously engaged and slidably connected to the slide rail 13; the slide rail 13 provides stable guidance for the movement of the threaded block 12, ensuring that the threaded block 12 can only move along a specific direction.

[0049] As Figure 1 shown, in some embodiments, the positioning seats 15 are at the four corners of the moving seat 14, and the positioning seats 15 are adapted to the shape and size of the template 16; the positioning seats 15 at the four corners can ensure that the template 16 does not shake or shift, guaranteeing the position stability of the watch case during the processing process.

[0050] As Figure 2 shown, in some embodiments, the watch case groove 17 on the template 16 raises the watch case above the plane, and the grinding disc 8 grinds it; the watch case is accurately placed in the groove, ensuring that it does not shift or shake during the processing process, and the template 16 can be designed according to the shape of the watch case.

[0051] As Figure 1As shown, in some embodiments, a limiting rail 18 is provided on the side of the frame 1, and the moving seat 14 is slidably connected to the limiting rail 18; when the stepping motor 9 drives the screw 11 to rotate, thereby driving the threaded block 12 and the moving seat 14 to move, the limiting rail 18 ensures that the moving seat 14 can only move along a specific direction without deviation or shaking.
