Of course, other components capable of realizing the revolution motion of the fixture assembly can also be used.

[0037] Specifically, the rotation component 6 includes a rotation drive source 61, a drive wheel 62, a transition wheel 63, and a driven wheel 64. The drive wheel 62 is connected to the rotation drive source 61, the transition wheel 63 is meshed with the drive wheel 62, the transition wheel is mounted on the revolution transmission shaft 52, the driven wheel 64 is meshed with the transition wheel 63, and the driven wheel 64 is mounted on the fixture component 3. In this embodiment, a spacer is provided on the revolution drive shaft, and a tapered roller bearing is mounted on the spacer. The shaft sleeve is connected to the spacer via the tapered roller bearing, and a deep groove ball bearing is mounted on the shaft sleeve. The transition wheel is connected to the shaft sleeve via the deep groove ball bearing. The driving wheel is a spur gear, and the transition wheel has an upper gear ring and a lower gear ring, both of which are spur gear rings. The driven wheel is a spur gear. A self-rotation drive source mounting bracket is provided inside the frame for mounting the self-rotation drive source. The lower gear rings of the driving wheel and the transition wheel are meshed together, and the upper gear ring of the transition wheel is meshed with the driven wheel. The self-rotation drive source is a motor and a reducer. The self-rotation drive source drives the transition wheel to rotate, the transition wheel drives the driven wheel to rotate, and the driven wheel drives the fixture assembly to rotate, thereby realizing the self-rotation motion of the fixture assembly. Of course, it is not limited to this; other components capable of realizing the self-rotation motion of the fixture assembly can be used. Specifically, the upper polishing assembly 2 includes an upper polishing lifting assembly 21, an upper polishing rotating assembly 22, and an upper polishing disc 23. The upper polishing rotating assembly 22 is connected to the upper polishing lifting assembly 21, and the upper polishing disc 23 is connected to the upper polishing rotating assembly 22. In this embodiment, the upper polishing disc is equipped with a grinding brush to facilitate polishing of the 3D surface of the product. The upper polishing lifting assembly drives the upper polishing disc to achieve lifting and lowering movement, and the upper polishing rotating assembly drives the upper polishing disc to rotate, thereby polishing the workpiece on the jig disc. Of course, it is not limited to this; any other assembly capable of polishing the workpiece on the jig disc can be used.

[0038] Specifically, a tension / compression sensor 24 is provided between the upper polishing lifting assembly 21 and the upper polishing rotating assembly 22. In this embodiment, a proportional regulating valve is also provided on the upper polishing rotating assembly. The proportional regulating valve controls the upper polishing lifting drive source to drive the upper polishing lifting transmission axis to move upward or downward based on the data fed back by the tension / compression sensor. The tension / compression sensor feeds back the measured data to the control system. When the upper grinding disc is not in contact with the workpiece, the data measured by the tension / compression sensor is the self-weight data of the upper grinding disc and the upper polishing rotating assembly. When the self-weight data of the upper grinding disc and the upper polishing rotating assembly is reset to zero and the upper grinding disc and the upper polishing rotating assembly contact the workpiece on the fixture assembly, the data measured by the tension / compression sensor is the measured pressure data of the upper grinding disc on the workpiece. The operator sets the target pressure according to the production pressure required by the working conditions through the control system. When the production pressure is less than the self-weight of the upper grinding disc and the upper polishing rotating assembly, the upper polishing lifting assembly needs to adjust the pressure of the upper grinding disc and the upper polishing rotating assembly. The system applies an upward force to partially offset the weight of the upper grinding disc and the upper polishing rotating assembly. When the target pressure is greater than the measured pressure, the control system controls the upper polishing lifting assembly to reduce the upward pressure on the upper grinding disc and the upper polishing rotating assembly. When the target pressure is less than the measured pressure, the control system controls the upper polishing lifting assembly to increase the upward pressure on the upper grinding disc and the upper polishing rotating assembly. When the production pressure is greater than the weight of the upper grinding disc and the upper polishing rotating assembly, the control system needs to apply a downward force to the upper grinding disc and the upper polishing rotating assembly to supplement the pressure and reach the target pressure. When the target pressure is less than the measured pressure, the control system controls the polishing assembly to reduce the downward pressure. When the target pressure is greater than the measured pressure, the control system controls the polishing assembly to increase the downward pressure. This achieves pressure compensation for the polishing assembly. Of course, it is not limited to this; any other system capable of polishing the workpiece and compensating for the pressure on the upper grinding disc can be used.
