Bearing ball missing detecting device

Abstract

The invention provides a bearing ball missing detecting device, comprising a device body. The device body is connected with an external PLC industrial computer and is controlled by the PLC industrialcomputer. The device body comprises a base, a lifting mechanism, a guiding mechanism, a detecting mechanism and a carrying mechanism. The lifting mechanism is located at a top rear end of the base. The guiding mechanism is located in front of the lifting mechanism. The guiding mechanism is connected with the lifting mechanism. The detecting mechanism is connected with the lifting mechanism. The detecting mechanism is located in front of the guiding mechanism. The carrying mechanism is located at the top front end of the base. The bearing ball missing detecting device of the invention detects whether balls have been installed in corresponding positions of a bearing to be detected by using a plurality of detecting probes at the bottom of a detecting head, thereby determining whether a ball is missing in the bearing to be detected. The operation is simple, the use is convenient, the detection accuracy is improved, and the product quality of the bearing is ensured.

Description

technical field [0001] The invention relates to the technical field of industrial testing equipment, in particular to a bearing lack of ball detection device. Background technique [0002] Rolling bearings are precision mechanical elements that change the sliding friction between the running shaft and the shaft seat into rolling friction, thereby reducing losses. Rolling bearings generally consist of four parts: inner ring, outer ring, balls and cage. The function of the inner ring is to cooperate with the shaft and rotate together with the shaft; the function of the outer ring is to cooperate with the bearing seat and play a dominant role; the cage can evenly distribute the balls and guide the balls to rotate for lubrication; the balls are evenly distributed by means of the cage The balls are distributed between the inner ring and the outer ring, and their shape, size and quantity directly affect the performance and life of the rolling bearing. [0003] In the mechanized ...

Problems solved by technology

Most of the lack of ball detection in the prior art adopts the method of vacuum suction to detect the air flow, that is, through the detection of the air flow, the bearing lack of the ball is detected separately. If the bearing lacks the ball, the air flow will be relatively large, and the identification is difficult. It is easy to cause missing or false detection of missing ball bearings, especially as the bearings become smaller and smaller, it is more difficult to identify the difference in air flow between missing ball bearings and qualified bearings with the above method, the detection efficiency is low, and the quality of the bearings is difficult. ensure
