Furthermore, the side wall of the hydraulic column is provided with a sliding groove matched with the end part of the top pressing plate.
Furthermore, the end part of the oilstone top pressing plate is inserted into the sliding groove and connected with a piston rod in the hydraulic column.
Further, an arc-shaped groove is formed in the left side of the upper surface of the top pressing plate.
Furthermore, the upper surface of the left end of the oilstone clamp body is provided with a through hole for inserting the oilstone clamp.
Further, the oilstone feeding device for the tapered roller bearing lapping outer raceway further comprises an oilstone side pressing block and a screw, the oilstone side pressing block is located on the left side of the oilstone, and one end of the screw penetrates through the left end of the oilstone clamp body and the oilstone clamp to tightly push the oilstone side pressing block against the left side of the oilstone.
The invention has the beneficial effects that:
1. by the aid of the device, the oilstone can be automatically subjected to abrasion compensation when abraded, and working efficiency of workers and utilization rate of equipment are improved;
2. the automatic oilstone feeding device has higher precision during wear compensation, thus greatly improving the working medium adding on the surface of the roller path, simultaneously reducing the operations of stopping the equipment, opening a door, manually pushing the oilstone, closing the door and the like by workers, and greatly improving the production efficiency of the equipment;
3. a constant pressure is applied to the top oilstone pressing plate through the hydraulic system through the hydraulic column, so that the danger that the oilstone is pinched off due to manual propelling of the oilstone is avoided.
