Bearing inner ring machining equipment

Abstract

The invention relates to the technical field of bearing machining, and discloses bearing inner ring machining equipment which comprises a base, a box body, an electric telescopic rod, a transmission assembly and a clamping assembly. The top end of the base is fixedly connected with the box body, the bottom end of the inner wall of the base is fixedly connected with the electric telescopic rod, and the inner wall of the box body is movably connected with the transmission assembly; and the top end of the transmission assembly is movably connected with the clamping assembly. According to the bearing inner ring machining equipment, a connecting column drives a fixed column to move, the fixed column drives the whole clamping assembly to move, and when a contact makes contact with the inner surface of a bearing inner ring, the contact drives a jacking column to move, so that a rotating column rotates relative to an arc-shaped column till the rotating column makes contact with the inner surface of the bearing inner ring and acting force is applied; and at the moment, the arc-shaped column and the rotating column make contact with the inner surface of the bearing inner ring so that the bearing inner ring can be clamped, due to the fact that the stress area of the bearing inner ring is large, the bearing inner ring is not prone to loosening and stable in clamping, and the follow-up machining process precision of a whole bearing is improved.

Description

technical field [0001] The invention relates to the technical field of bearing processing, in particular to a bearing inner ring processing equipment. Background technique [0002] Bearings are parts used to support the rotation of mechanical parts or mechanical mechanisms in mechanical equipment. Its function is to reduce friction in motion. The update and iteration speed of modern mechanical equipment is getting faster and faster, and the requirements for bearing precision are also increasing. The higher the height, the existing bearing inner ring often needs to be fixed when the bearing inner ring is processed. However, when the bearing ring is fixed in this way, the bearing ring is easy to loosen. This is caused by the small stress area of ​​the inner ring of the fixed bearing, which will cause a certain degree of impact on the subsequent grinding and polishing of the inner ring of the bearing. The precision of the inner ring of the bearing is reduced. Therefore, we pro...

[0002] Bearings are parts used to support the rotation of mechanical parts or mechanical mechanisms in mechanical equipment. Its function is to reduce friction in motion. Modern mechanical equipment is updated and iterated. The speed is getting faster and faster, and the requirements for bearing precision are getting higher and higher. The existing bearing inner ring often needs to be fixed when the bearing inner ring is processed, but the existing bearing inner ring fixing device, the fixing method of the bearing Single, most of the time, the inner ring of the bearing is fixed from both sides inside the bearing ring, but the bearing ring is easy to loosen when the bearing ring is fixed in this way, which is caused by the small stress area of ​​the inner ring of the fixed bearing, which will make the subsequent It has a certain degree of influence on the grinding and polishing of the inner ring of the bearing, which reduces the precision of the inner ring of the bearing. Therefore, we propose a processing equipment for the inner ring of the bearing with stable clamping.
