Improved semi-automatic internal grinder

Abstract

The invention discloses an improved semi-automatic internal grinder. The improved semi-automatic internal grinder comprises a power device and a feeding channel, wherein a rod frame is arranged on the power device, a long rod is connected to the rod frame, the long rod and the power device are located on the two sides of the feeding channel respectively, and one end of the top face of the long rod is gradually lifted from the end close to the feeding channel to the end deviating from the feeding channel. The improved semi-automatic internal grinder is simple in structure, and the material returning and feeding process of a rolling wheel can be achieved just through small pushing force.

Description

technical field [0001] The invention relates to a grinding machine, in particular to a semi-automatic bearing internal grinding machine. Background technique [0002] Internal grinding machines are usually used in the internal grinding of bearing rings. There is a kind of centerless internal grinding machine for internal grinding machine. When working, the outer circle of the bearing ring is supported on the roller. The end face of the bearing ring is sucked by the magnetic chuck and driven to rotate, but it can float slightly to ensure the concentricity of the inner and outer circles. [0003] The centerless internal grinding machine used in mass production requires a high degree of automation. During the grinding process, it can be loaded automatically or manually. The bearing ring passes through the feeding channel and leads to the position of the roller. After grinding, the roller Rotating under the action of the hydraulic system, the bearing ring is withdrawn from the ...

AI Technical Summary

Problems solved by technology

[0004] In actual use, when the roller rotates to return the material, it is necessary to jack up the bearing ring in the feeding channel. If the bearing ring is heavy, the roller rotation will not be able to lift the bearing ring smoothly due to insufficient thrust of the hydraulic system. , so that the return of the material cannot be realized normally, and the feeding process after the return of the material cannot be realized, so that the automatic operation cannot be realized

[0005] In this case, one option is to increase the thrust of the hydraulic system on the rotation of the rollers. However, this will also encounter some problems: First, during the process of returning materials, the bearing rings that
