[0024] When the workpiece body 14 is to be fixed on the fixed table 1 by a clamp, the workpiece body 14 is first placed on the base 4, and then the laser level 3 is started to check the horizontal accuracy of the workpiece body 14 when clamped and fixed. Then, the clamping plate 11 is rotated so that the front end of the clamping plate 11 is pressed against the upper surface of the workpiece body 14 while tightening the nut 10. The real-time data transmitted by the pressure sensor 12 is monitored through the data acquisition display module 16. At the same time, the support force of the support plate 8 on the rear end of the clamping plate 11 can be adjusted to ensure that the clamping pressure of the clamping plate 11 at the four corners of the upper surface of the workpiece body 14 on the workpiece body 14 is relatively uniform and reaches a stable clamping degree of the workpiece body 14, thereby ensuring that the clamping accuracy of the workpiece body 14 is more precise and that the milling accuracy of the workpiece body 14 by the processing tool group 15 is higher.

[0025] Embodiment 2

[0026] On the basis of the first embodiment, in order to facilitate the horizontal accuracy of the workpiece body 14 when clamping and fixing the workpiece body 14, a fixing plate 2 is provided with a plate-shaped structure, the fixing plate 2 is fixedly connected to the rear surface of the fixing table 1, and the bottom bracket 4 is fixedly connected to the four corners of the upper surface of the fixing table 1, and the bottom bracket 4 is a cylindrical structure;

The laser level 3 on the upper surface of the fixed plate 2 can not only be used to check whether the workpiece body 14 is level when clamped and fixed, but also can be used to check whether the fixed table 1 and the base 4 are level when set, thereby ensuring the clamping accuracy and processing accuracy of the workpiece body 14.

Then, the clamping plate 11 is rotated so that the front end of the clamping plate 11 is pressed against the upper surface of the workpiece body 14, and the nut 10 at the upper end of the clamping threaded rod 9 on the upper surface of the clamping base 5 is tightened, and the data acquisition display module 16 is used to monitor the real-time data transmitted by the pressure sensor 12 through the acquisition line 13. At the same time, the support force of the support plate 8 on the rear end of the clamping plate 11 can be adjusted by rotating the adjustment threaded rod 7 in the threaded groove 6 to ensure that the clamping pressure of the clamping plate 11 at the four corners of the upper surface of the workpiece body 14 on the workpiece body 14 is relatively uniform and reaches the degree of stable clamping of the workpiece body 14, thereby ensuring that the clamping accuracy of the workpiece body 14 is more accurate, and the milling accuracy of the workpiece body 14 by the processing tool group 15 is higher.

[0031] In actual use, when the workpiece body 14 is to be fixed on the fixed table 1 by a clamp, the workpiece body 14 is first placed on the base 4, and then the laser level 3 is started to check the horizontal accuracy of the workpiece body 14 when clamped and fixed.

This operation method may cause the clamping force and stability of the clamp to the workpiece to be inconsistent, which may lead to the problem of insufficient accuracy of the workpiece clamping.
