Polishing and screening device for rolling bodies for bearings

Abstract

The invention provides a polishing and screening device for rolling bodies for bearings. The polishing and screening device comprises a base, a box and a polishing device. The box is installed on the base and can rotate relative to the base. A quantitative feeding hopper is arranged at the upper end of one side of the box. A partition plate is arranged in the box. The interior of the box is divided into a polishing area and a collecting area by the partition plate. The polishing device is arranged in the polishing area and comprises a plurality of U-shaped pipes which are arranged at equal intervals. Every two adjacent U-shaped pipes are connected through a semicircular elbow, so that a polishing channel is formed. Protrusions are distributed on the inner walls of the U-shaped pipes and the inner walls of the semicircular elbows correspondingly. The feeding end of the polishing channel is connected with the quantitative feeding hopper. The discharging end of the polishing channel is connected with the collecting area. According to the polishing and screening device, the rolling bodies are added into the polishing device through the quantitative feeding hopper, the box rotates, the rolling bodies can roll along the polishing channel and collide and rub with the protrusions on the inner walls of the U-shaped pipes and the inner walls of the semicircular elbows, the contact area between the rolling bodies and the protrusions is large, and the working efficiency is high.

Description

technical field [0001] The invention relates to the technical field of processing rolling bodies for bearings, in particular to a grinding and screening device for rolling bodies for bearings. Background technique [0002] In the manufacturing process of rolling elements for bearings, the surface of the rolling elements needs to be polished to achieve the best use effect of the bearings. In the grinding process, a cylindrical grinding box with a grinding layer in the inner cavity can be used. When the grinding box rotates, the rolling body is allowed to roll on its inner wall and rub against the inner wall to achieve the grinding effect. The inner wall of the ordinary grinding box is a simple arc surface, the grinding area is small, and the grinding efficiency is low; in addition, the rolling elements of different specifications cannot be separated in time, and the powder chips from grinding cannot be discharged in time. It needs to wait until the rolling elements are polish...

AI Technical Summary

Problems solved by technology

The inner wall of the ordinary grinding box is a simple arc surface, the grinding area is small, and the grinding efficiency is low; in addition, the rolling elements of different specifications cannot be separated in time, and the powder chips from grinding cannot be discharged in time. It needs to wait until the rolling elements are polished and poured out. Then the powder is separated, the surface of the rolling element after grinding is stained with powder, which needs to be further removed, which increases the labor process
