Description

Technical Field

[0001] The utility model relates to the technical field of grinding bearing rings, in particular to a turning fixture for grinding bearing rings. Background Art

[0002] Bearing rings are one of the commonly used parts in mechanical equipment. Bearing rings are annular parts of radial rolling bearings with one or more raceways. The production process of bearing rings includes forging, heat treatment, grinding detection and identification management. During the processing of bearing rings, both sides of the bearing rings need to be polished. Traditional bearing rings are generally removed and turned over manually.

[0003] Patent document CN216802650U discloses a bearing ring flipping device, "relating to the field of bearing ring processing technology, solving the problem that the existing bearing ring flipping is mostly done by manual screening and then flipping, which leads to low work efficiency. It includes a feeding mechanism, and the main body of the feeding mechanism is a U-shaped frame structure design. In the utility model, the limit component in the flipping mechanism is started to move toward the ring side, and the ring is clamped by the clamping component and the arc block in the flipping component. After clamping is completed, the flipping motor in the flipping component drives the ring to flip, thereby achieving a more practical purpose."

[0004] When the above device is in use, the adjustment component in the detection mechanism is adjusted according to the size of the processed ring, and the degree of flipping of the adjustment component around the extension component is adjusted by adjusting the adjustment rod installed on the outside of the adjustment component. An angle ruler is also provided on the outside of the extension component, so precise adjustment can be achieved. However, when the arc block and the ring are fixing the bearing, the arc block needs to clamp the outer surface of the bearing ring, resulting in the need to adjust the clamping position of the bearing multiple times when grinding the bearing ring, which increases the number of times the bearing is adjusted, making the operation of the staff more complicated and easily resulting in low bearing grinding efficiency, so it is necessary for the staff to make improvements.

[0036] When the bearing ring is polished by this device, the second pull ring 24 is pulled upward, so that the second pull ring 24 drives the limiting rod 22 at the bottom to move upward and retract into the inner wall of the connecting box 21, and then the connecting plate 19 is pushed, so that the connecting plate 19 drives the sliding block 18 at the bottom to slide and make the grinding stone 20 contact the bearing ring, and then the second pull ring 24 is released, so that the spring 23 rebounds and pushes the limiting rod 22, so that the limiting rod 22 is inserted into the inner wall of the operating platform 1, so that the bearing ring can be polished with the grinding stone 20.

[0037] Working principle: put the bearing ring on the surface of the operating box 6 and rotate the screw 9 to insert it into the operating box 6. At this time, the pushing block 10 pushes the pressing block 7, so that the pressing block 7 extends out of the operating box 6 and the anti-slip plate 8 presses against the inner wall of the bearing ring, thereby completing the fixation of the bearing ring. Then, the limit rod 22 is retracted into the inner wall of the connecting box 21, and the connecting plate 19 is pushed, so that the grinding stone 20 contacts the bearing ring. Then, the first driving motor 3 is powered on, so that its output end drives the bearing ring to rotate, and the bearing ring is ground on the surface of the grinding stone 20. After grinding, the electric telescopic rod 12 is turned on. The power supply drives the flip clamp ring 17 to move to the bottom of the operating box 6, and the screw rod 9 is rotated in the opposite direction to separate it from the operating box 6. At this time, the top pressure block 7 is disengaged from the fixation, so that the bearing ring falls and is placed on the flip clamp ring 17. The electric telescopic rod 12 is extended again, so that the bearing ring is outside the operating box 6. The second drive motor 15 is powered on, so that the flip clamp ring 17 rotates 180 degrees, and then the electric telescopic rod 12 is retracted, so that the bearing ring is on the surface of the operating box 6, and then the screw rod 9 is rotated and inserted into the operating box 6, so that the anti-slip plate 8 supports the bearing ring, so that it can be polished again.
