[0030] In this utility model, the working principle is as follows:

[0031] ① The workpiece to be polished is mounted on the polishing station 11, and the polishing tool 50 is mounted on the driving device 20. As a preferred embodiment of the driving device 20, the driving device 20 includes an X-axis motion platform 21, a Y-axis motion platform 22 and a rotating B-axis 23. The X-axis motion platform 21 is mounted on the frame 10, the Y-axis motion platform 22 is mounted on the X-axis motion platform 21, the rotating B-axis 23 is mounted on the Y-axis motion platform 22, and the polishing tool 50 is mounted on the rotating B-axis 23; and the polishing station 11 is provided with a rotating B-axis for driving the workpiece to be polished to rotate. When the driving device 20 drives the polishing tool 50 close to the workpiece to be polished, the workpiece to be polished will be polished, thereby processing the desired optical surface;

[0032] ② In one embodiment, a precision optical surface polishing machine with in-situ finishing and measurement further includes a Z-axis motion platform 70 disposed on the polishing station 11, and the workpiece to be polished is mounted on the Z-axis motion platform 70, which can drive the rotating B axis to move along the Z-axis direction, and cooperate with the X-axis motion platform 21 and the Y-axis motion platform 22 to realize three-axis motion. Of course, the Z-axis motion platform 70 can also be integrated into the driving device 20;

[0033] ③ During the polishing process, the thickness of the polishing tool 50 is detected at certain time intervals. Specifically, the driving device 20 drives the polishing tool 50 to move to the detection device 30. If the detection device 30 detects that the thickness of the polishing tool 50 meets the current processing requirements, the driving device 20 drives the polishing tool 50 back to the polishing station 11 to continue polishing. If the detection device 30 detects that the thickness of the polishing tool 50 does not meet the current processing requirements, the driving device 20 drives the polishing tool 50 to move to the dressing station 13 for dressing. Dressing is performed according to the error between the detection value and the standard value until it meets the current processing requirements again. Then, the driving device 20 drives the polishing tool 50 back to the polishing station 11 to continue polishing.

[0034] ④ The advantage of the utility model is that the above structure realizes the fully automated operation of polishing the optical surface and dressing the polishing tool, which greatly improves the processing efficiency of the optical surface and has very good practicality.

[0035] As a preferred embodiment of the rotating B-axis 23, the rotating B-axis 23 is provided as a divider.

[0036] In one embodiment, the polishing station 11, the inspection station 12 and the trimming station 13 are located on the same plane; specifically, they are located on the plane where the X-axis is located. By optimizing the position layout of each device, the driving stroke of the driving device 20 can be reduced, which is conducive to further improving the polishing efficiency.

[0037] In one embodiment, a precision optical surface polishing machine with in-situ trimming and measurement also includes a centering measurement device 60 installed on the driving device 20, which is used to perform centering measurement on the workpiece to be polished on the polishing station 11; the centering measurement device 60 serves as a positioning process before the polishing process, and can perform fixed-point measurement on the position of the workpiece to be polished, thereby providing a polishing reference for the polishing of the polishing tool 50.

These equivalent modifications and substitutions are all included in the scope defined by the claims of this application.
