[0018] In this embodiment, refer to Figures 1-3The utility model provides an ultra-precision machine for preventing oil stone from loosening, which comprises an ultra-precision machine body 1, an operation table 2 arranged in the ultra-precision machine body 1, a mounting disc 3 arranged above the operation table 2 of the ultra-precision machine body 1, a hydraulic cylinder mechanism arranged on the ultra-precision machine body 1 and used for controlling the mounting disc 3 to slide back and forth along a straight line, the hydraulic cylinder mechanism being composed of a cylinder body, a piston and a hydraulic driver.

[0019] The mounting disc 3 is provided with clamping mechanisms at four corners of the oil stone loading disc 4, the clamping mechanisms are arranged in pairs of symmetry, the clamping blocks 14 extending from the clamping mechanisms are simultaneously moved towards the oil stone block 5, and the oil stone block 5 arranged in the middle is clamped and fixed by the clamping blocks 14 arranged at the four corners of the oil stone loading disc 4.

[0020] Specifically, the clamping mechanism comprises a cylinder 6, a fixed seat 7, a movable support 8, a swing rod 12 and a connecting block 10. Figure 3 As shown in the accompanying drawings, the clamping mechanism comprises a cylinder 6, a fixed seat 7, a movable support 8, a swing rod 12 and a connecting block 10.

[0021] The front part of the pneumatic rod of the output end of the cylinder 6 is fixedly connected with the movable support 8, the fixed seat 7 is provided with a vertical fixed column 11, the lower end of the fixed column 11 is rotatably connected with the swing rod 12, and the fixed column 11 is parallel to the pneumatic rod of the output end of the cylinder 6.

[0022] The movable support 8 is horizontally arranged and changes in height through the control of the cylinder 6. The front end of the movable support 8 towards the swing rod 12 is rotatably connected with a second connecting rod 13, the active end of the second connecting rod 13 is rotatably connected with the middle part of the rod body of the swing rod 12, and the rear end of the movable support 8 is rotatably connected with a first connecting rod 9.
