the utility model provides an extension dysmorphism bearing inner race end face grinding device, includes pay-off board, first fixed floor and the fixed floor of second, the pay-off hole has been seted up on the pay-off board, first fixed floor and the fixed floor of second all set up on the pay-off board, and serve and all be equipped with the bearing roller on the fixed floor of first fixed floor and second, the one end that first fixed floor and the fixed floor of second are close to the bearing roller all is located the edge of pay-off hole, be equipped with special-shaped bearing in the pay-off hole.
Preferably, the first fixing rib plate and the second fixing rib plate are provided with long round holes, and the long round holes are matched with threaded holes formed in the feeding plate.
Preferably, one side of the feeding plate is provided with an upper grinding wheel, and the other side of the feeding plate is provided with a lower grinding wheel.
Preferably, a screw is arranged in the long round hole and is in threaded connection with a threaded hole formed in the feeding plate.
Compared with the prior art, the beneficial effects of the utility model are that:
1. during feeding, the special-shaped bearing is laterally placed between the two bearing rollers, and the angles of the two bearing rollers are designed according to the center of gravity of a processed workpiece, so that the workpiece is prevented from overturning.
2. The feeding plate feeds the workpiece into the space between the two grinding wheels for grinding, two end faces can be ground at one time, the workpiece rotates along with the grinding wheels due to the floating support of the outer circle of the bearing during grinding, and the grinding quality and the grinding efficiency are good.
