Device for detecting coaxiality of bearing inner ring

Abstract

The invention relates to a bearing inner ring coaxiality detection device which comprises a rack, an inclined discharging slide way is arranged on the rack, a detection mechanism is arranged on the rack and comprises a sensor, a ball, a lifting part and a rotating assembly; wherein the sensor is installed on the rack in a sliding mode, the ball is installed on the sensor in a rotating mode, the lifting piece is installed on the rack and drives the sensor to move in a reciprocating mode, and the ball is pressed into an outer channel of the bearing inner ring under the action of the lifting piece; the rotating assembly is installed on the discharging sliding way and connected with the bearing inner ring, the sensor is connected with the rotating assembly, and the rotating assembly drives the bearing inner ring to rotate and can push the bearing inner ring out of the discharging sliding way. The bearing inner ring separation device has the effects that unqualified bearing inner rings are separated out, the number of unqualified bearing inner rings in the bearing inner rings is reduced, and therefore the qualified rate of the bearing inner rings is increased.

Description

technical field [0001] The present application relates to the technical field of bearing processing, in particular to a detection device for the coaxiality of a bearing inner ring. Background technique [0002] Bearings include bearing outer rings, bearing inner rings and balls. Bearings are components that fix and support shaft rotation in mechanical equipment. They have the function of reducing the friction coefficient during power transmission and ensuring the rotation accuracy of the shaft. The processing of bearings. [0003] In the related technology, the outer groove of the inner ring of the bearing is formed by turning on the automatic bearing turning production line, including the feeding and discharging slideway, the feeding device, the drive shaft, the turning tool and the blanking and discharging slideway. The ring is close to the drive shaft through the feeding and discharging slideway. The feeding device sets the inner ring of the bearing on the drive shaft, so...

AI Technical Summary

Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventor believes that there are the following defects: when the inner ring of the bearing is sleeved on the drive shaft, there is a gap between the inner ring of the bearing and the drive shaft , when the turning tool is turning the outer raceway, the turning tool squeezes the inner ring of the bearing and causes a relative displacement between the inner ring of the bearing and the drive shaft, making the inner ring of the bearing and the drive shaft out of axis, and may make the outer raceway and the bearing The coaxiality error of the inner ring exceeds the coaxiality tolerance, so that the unqualified bearing inner ring is mixed into the qualified bearing inner ring, thereby reducing the qualified rate of the bearing inner ring
