For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two elements. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0025] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] Reference Figures 1 to 4This application provides a bearing precision machining fixture, including a worktable 1, a clamping assembly 2 inside the worktable 1, and a grinding assembly 3 on the top of the worktable 1. The clamping assembly 2 includes a rotating disk 21, which is rotatably connected to the inside of the worktable 1. A sliding groove 24 is opened inside the rotating disk 21, and a limit rod 25 is fixedly installed inside the sliding groove 24. A moving block 23 is slidably connected to the outside of the limit rod 25 and inside the sliding groove 24. A clamping block 22 is fixedly installed on the top of the moving block 23, and a bearing sleeve 4 is provided between the clamping blocks 22.

[0027] The inner wall curvature of clamping block 22 is the same as the outer wall curvature of bearing sleeve 4, and the outer wall curvature of clamping block 22 is the same as the inner wall curvature of bearing sleeve 4. A screw 26 is rotatably connected to the bottom of rotating disk 21, and a lifting block 28 is screwed to the outside of screw 26. A connecting rod 29 is hinged between lifting block 28 and corresponding moving block 23. A knob 27 is fixedly installed at the bottom of screw 26, and screw 26 is rotatably connected to the center of the bottom of rotating disk 21.

[0028] In this embodiment, when fixing the bearing sleeve 4, the screw 26 is rotated by turning the knob 27. The rotation of the screw 26 can drive the outer lifting block 28 to move up and down. The up and down movement of the lifting block 28 can push or pull the multiple connecting rods 29 on the outside to move synchronously. The synchronous movement of the connecting rods 29 can move the upper moving block 23 synchronously outward or inward, ensuring that the bearing sleeve 4 can be fixed at the center of the rotating disk 21. By placing the bearing sleeve 4 on the outside of the moving block 23, the clamping block 22 can be moved and fitted into the inside of the bearing sleeve 4, which is convenient for grinding the outside. By placing the bearing sleeve 4 inside the moving block 23 and moving the clamping block 22 to fit into the outside of the bearing sleeve 4, it is convenient for grinding the inside. Thus, the bearing sleeve 4 can be easily ground both inside and outside after fixing. In addition, the clamping block 22 is provided with various specifications to accommodate bearing sleeves 4 of different specifications.

[0029] Reference Figures 1 to 4 In one aspect of this embodiment, the grinding assembly 3 includes a horizontal plate 31, an electric slide rail 34 is fixedly installed at the bottom of the horizontal plate 31, a track slider 35 is slidably connected to the outer side of the electric slide rail 34, a second hydraulic rod 36 is fixedly installed at the bottom of the track slider 35, a power block 37 is fixedly installed at the bottom of the second hydraulic rod 36, a motor is fixedly installed inside the power block 37, and a grinding head 38 is fixedly installed at the output end of the motor, with the grinding head 38 located below the power block 37.

[0030] A first hydraulic rod 33 is fixedly installed on the top of the workbench 1. Connecting blocks 32 are fixedly installed at the bottom of both ends of the horizontal plate 31. The output end of the first hydraulic rod 33 is fixedly installed at the bottom of the connecting blocks 32. A rotating ring 312 is fixedly installed at the bottom of the rotating disk 21. A gear ring 39 is fixedly installed at the bottom of the rotating ring 312. A power motor 311 is fixedly installed at the bottom of the workbench 1. A gear 310 is fixedly installed at the output end of the power motor 311. The gear 310 meshes with the gear ring 39.

[0031] In this embodiment, during grinding, the electric slide rail 34 is activated to move the track slider 35, thereby moving the grinding head 38 inward and outward. The grinding head 38 can move up and down by activating the first hydraulic rod 33 and the second hydraulic rod 36 in cooperation. During grinding, the grinding head 38 is respectively attached to the inner and outer sides of the bearing sleeve 4. The power motor 311 and the motor are activated, and the motor drives the grinding head 38 to rotate to grind the bearing sleeve 4. During grinding, the power motor 311 drives the gear 310 to rotate, and the gear 310 rotates the gear ring 39 and the rotating ring 312, thereby driving the rotating disk 21 and the internal bearing sleeve 4 to rotate. By rotating the bearing sleeve 4 during grinding, the complete grinding of the bearing sleeve 4 is ensured, and the freely movable grinding head 38 ensures that bearing sleeves 4 of various specifications can be ground.

[0032] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0033] Working principle: When fixing the bearing sleeve 4, turn the knob 27, and the screw 26 will rotate accordingly. The rotation of the screw 26 will drive the lifting block 28 to move up and down. The movement of the lifting block 28 will push or pull the connecting rod 29 to move synchronously. The synchronous movement of the connecting rod 29 will cause the upper moving block 23 to move synchronously outward or inward. When the bearing sleeve 4 is placed on the outside of the moving block 23, the clamping block 22 will move and fit against the inside of the bearing sleeve 4; when the bearing sleeve 4 is placed on the inside of the moving block 23, the clamping block 22 will move and fit against the outside of the bearing sleeve 4, thereby fixing the bearing sleeve 4.

[0034] During the grinding process, the electric slide rail 34 is activated, which drives the track slider 35 to move, thereby causing the grinding head 38 to move inward and outward in the horizontal direction. At the same time, the first hydraulic rod 33 and the second hydraulic rod 36 are activated, and the two work together to achieve the up and down movement of the grinding head 38 in the vertical direction. When grinding the bearing sleeve 4 inside and out, the grinding head 38 is placed against the inner and outer sides of the bearing sleeve 4 respectively. Then, the power motor 311 and the motor are activated. The motor drives the grinding head 38 to rotate to grind the bearing sleeve 4. The power motor 311 drives the gear 310 to rotate. The rotation of the gear 310 drives the gear ring 39 and the rotating ring 312 to rotate, thereby driving the rotating disk 21 and the internal bearing sleeve 4 to rotate, realizing the all-round grinding of the bearing sleeve 4.
