Description

Device capable of reducing damage to steel ball transferring and impacting platform

Technical Field

The utility model relates to the technical field of steel ball production equipment, in particular to a device capable of reducing damage to a steel ball transferring and impacting platform.

Background

The shape error and surface roughness of the precision bearing steel ball are very high. The spherical error of the G10 grade bearing steel ball which is the most commonly used is not more than 0.25 μm, and the surface roughness Ra is not more than 0.020 μm.

In the last processes of the production process, particularly in the transfer of the processes after the initial grinding, the steel balls are discharged from a ball outlet of the equipment and drop into a bucket groove in a parabolic manner, so that impact injury is generated. In order to improve the quality of steel balls, for example, a steel ball collecting box in chinese patent CN202021383888.9 is provided with a plurality of separators in the collecting box, so that the steel balls can directly fall into different storage areas along the plurality of separators, and buffer the steel balls when falling, so as to avoid the strong impact between the falling steel balls and the box body and the impact to the steel balls falling before, thereby avoiding the problem of scratch between the steel balls due to impact.

However, for small miniature steel balls, the surface machining allowance is smaller than 2.5 mu m before the final precision grinding process is finished, the spherical shape of the steel balls can be directly affected by the platform damage generated by impact, and the spherical error and the surface roughness are increased. Therefore, how to reduce the impact on the surface of the steel ball in the transferring process, reduce the drop of the steel ball and protect the spherical surface is an important measure.

Disclosure of Invention

Aiming at the problems, the utility model provides a device capable of reducing the damage of a steel ball transferring and impacting platform.

In order to achieve the above purpose, the utility model adopts the following technical scheme:
