Description

Technical Field

[0001] The invention relates to a testing tool, in particular to a device for testing a steel ball sleeve ball socket track. Background Art

[0002] The steel ball sleeve is surrounded by multiple rows of inclined steel balls and can be used in conjunction with the shaft and sleeve. The interference fit can achieve gapless assembly and the combination accuracy is extremely high. Therefore, it is widely used in the mold industry, machinery and equipment industry, and industries with high-precision operation or movement.

[0003] During processing, generally multiple ball sockets are processed first, and then the steel balls are installed in them. The steel balls can move flexibly and are not easy to fall off. The ball sockets need to be arranged according to a certain ball socket track, otherwise it will lead to uneven distribution of steel balls, making it impossible for the steel ball set to maintain uniform characteristics, affecting the precision of the steel ball set's rotation.

[0004] Therefore, it is necessary to detect the ball socket track, but it is difficult to identify with the naked eye whether the ball socket deviates from the ball socket track. It needs to be detected by a special inspection fixture. Currently, there is no inspection fixture on the market that can detect the ball socket track. Summary of the invention
