All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-2, the present invention provides a force compensation mechanism for a polishing apparatus, and the force compensation mechanism mainly includes the following structure:

From the above, when the force compensation mechanism of the utility model utilizes the disclosed structure to perform polishing compensation, the principle is as follows:
the workpiece is fixed on the workpiece fixing component, and the polishing head is contacted with the workpiece during polishing, so that the workpiece and the workpiece fixing component are extruded; the force control sensor 4 detects real-time pressure of the workpiece fixing component in the horizontal (Y-axis) direction and the longitudinal (Z-axis) direction in the polishing process in real time, the force control sensor 4 feeds back data according to the detected pressure, and the Y-axis driving component 2 and the Z-axis driving component 3 receive the data fed back by the force control sensor 4 and execute corresponding driving;
for example, when the Z-axis pressure detected by the force control sensor 4 exceeds a set threshold, it indicates that the polishing pressure applied to the workpiece is too large, and at this time, the force control sensor 4 and the workpiece fixing component are driven to move down along the longitudinal direction (Z-axis) based on the driving of the Z-axis driving component 3, so as to reduce the pressure applied to the workpiece; otherwise, the grinding pressure received by the workpiece in the Z-axis direction can be increased. In addition, based on the same detection and feedback principle, the Y-axis driving component 2 can be used for compensation and adjustment of Y-axis stress.
In addition, in the compensation adjustment process, according to the actual polishing requirement of the workpiece, the rotating assembly can be used for driving the workpiece fixing assembly to rotate freely in the horizontal plane. Specifically, the above-mentioned rotating assembly includes:
the rotary divider 5 is arranged at the top of the force control sensor 4, and the workpiece fixing component is arranged on an output shaft of the rotary divider 5;
the rotator motor 6 is in transmission connection with the rotary divider 5, and the rotator motor 6 drives the workpiece fixing component to rotate through the rotary divider 5;
