[0007] Furthermore, the two main plates are both curved in an arc shape, and arc-shaped inwardly concave grooves are provided on opposite sides of the two main plates.
[0008] Furthermore, a first anti-slip rubber pad is fixedly adhered to the inner wall of the arc-shaped concave groove on the opposite side of the two main splints, one end of the adjustment port extends to one side of the first anti-slip rubber pad, and the surface of the first anti-slip rubber pad is provided with vertical wavy raised patterns.
[0009] Furthermore, the auxiliary fixer includes two electric telescopic rods, which are respectively fixedly installed on one side of the inner wall of the fixing frame, and a secondary clamping plate is installed between the output ends of the two electric telescopic rods and inside the adjustment port.

[0011] Furthermore, a second anti-slip rubber pad is fixedly adhered to the inner concave side of the auxiliary splint, and the surface of the second anti-slip rubber pad is provided with vertical wavy raised lines.
[0012] Beneficial effects of the utility model:
[0013] By starting the electric push rod connecting the two fixing frames, the two main clamping plates are driven to move closer and clamp the inner ring of the bearing. Then, the two auxiliary clamping devices are started to push the two secondary clamping plates to move closer to each other, clamping and fixing the roller groove part of the bearing ring, thereby effectively increasing the contact area between the fixing tool and the bearing ring, thereby increasing the friction and improving the stability of the bearing fixing processing.

The two main splints 5 are both arc-shaped, so that the main splint 5 can fit the curvature of the outer ring surface of the inner ring of the bearing. The opposite sides of the two main splints 5 are provided with arc-shaped concave clamping grooves, and the inner walls of the arc-shaped concave clamping grooves on the opposite sides of the two main splints 5 are fixedly adhered with a first anti-slip rubber pad 6. One end of the adjusting port 7 extends to one side of the first anti-slip rubber pad 6. The surface of the first anti-slip rubber pad 6 is provided with vertical wavy raised patterns. The first anti-slip rubber pad 6 can increase the contact friction between the main splint 5 and the outer ring of the inner ring of the bearing, thereby effectively improving the clamping stability of the inner ring of the bearing.
[0023] See also Figure 2-4The auxiliary holder 8 includes two electric telescopic rods 81, both of which are connected to an external power supply. The two electric telescopic rods 81 are fixedly mounted on one side of the inner wall of the fixing frame 4. A secondary clamping plate 82 is installed between the output ends of the two electric telescopic rods 81 and inside the adjustment port 7. The secondary clamping plate 82 is curved so that the secondary clamping plate 82 can fit the outer ring surface of the inner ring of the bearing. A concave arc-shaped clamping groove is provided on one side of the secondary clamping plate 82. The electric telescopic rods 81 inside the two auxiliary holders 8 are controlled by the same power switch. When the electric telescopic rods 81 inside the two auxiliary holders 8 are in the When started simultaneously, the two auxiliary clamping plates 82 can be pushed together at the same frequency to shorten the distance between them. The two auxiliary clamping plates 82 are used to clamp and fix the concave part in the middle of the outer ring of the inner ring of the bearing. A second anti-slip rubber pad 83 is fixedly adhered to the inner concave side of the auxiliary clamping plate 82. The surface of the second anti-slip rubber pad 83 is provided with vertical wavy raised lines. The second anti-slip rubber pad 83 can increase the clamping friction between the auxiliary clamping plate 82 and the inner ring of the bearing, so that during the polishing and grinding process of the inner ring surface of the bearing inner ring, the inner ring of the bearing will not rotate with the grinding roller, effectively improving the production and processing efficiency of the bearing. The two auxiliary fixers 8 are installed in a mirror image stacked structure.
[0024] Specific implementation method: By placing the inner ring of the bearing to be processed on the top of the base plate 1, and starting the electric push rods 3 connected to the two fixing frames 4 at the same time, each electric push rod 3 is connected to an external power supply and is provided with the same power control switch, so that the two fixing frames 4 can be pushed to move and approach each other at the same time, and then the two main splints 5 can be driven to move close to each other and clamp the inner ring of the bearing.

Since the outer ring surface of the inner ring of the bearing is provided with an annular rolling groove for matching roller installation, the main splint 5 cannot contact the annular rolling groove during the process of clamping and fixing the inner ring of the bearing, so it is necessary to start the electric telescopic rods 81 inside the two auxiliary fixers 8. The two auxiliary fixers The electric telescopic rods 81 inside the fixer 8 are all controlled by the same power switch. The electric telescopic rods 81 inside the two auxiliary fixers 8 simultaneously push the two auxiliary clamps 82 to move and approach each other, and the two auxiliary clamps 82 are moved out through the adjustment port 7. The adjustment port 7 is located in the middle of the main clamp 5. The auxiliary clamp 82 is curved in an arc shape, so that the auxiliary clamp 82 can fit the outer ring surface of the inner ring of the bearing. When the bearing ring is clamped and fixed by the two main clamps 5, the adjustment port 7 can be aligned with the rolling groove on the outer ring surface of the bearing ring for installing the roller, and the roller rolling groove part of the bearing ring can be clamped and fixed by the auxiliary fixer 8, thereby effectively increasing the contact area between the fixing tool and the bearing ring, thereby increasing the friction and improving the stability of the bearing fixing processing.
[0025] The surfaces of the first anti-slip rubber pad 6 and the second anti-slip rubber pad 83 are both provided with vertical wavy raised patterns, which can increase the friction when the main splint 5 and the auxiliary splint 82 are in contact with the outer ring surface of the inner ring of the bearing, so that during the polishing and grinding process of the inner ring surface of the bearing ring, the bearing ring will not rotate with the grinding roller, and the bearing ring will not cause surface wear due to clamping, thereby effectively improving the production and processing efficiency and processing quality of the bearing.
