Description

Technical Field

[0002] With the rapid development of my country's economy, the market demand for circular time gratings has increased. Circular time grating manufacturers urgently need to increase their production capacity. As a crucial part of the product manufacturing process, the current testing fixtures for circular time gratings cannot meet the requirements of production efficiency. Therefore, the development of rapid testing fixtures for circular time gratings is urgently needed.

[0003] The current fixture requires a complex process: after installing the timer rotor onto the rotor fixture on the turntable, a dial indicator is used to adjust the concentricity of the timer rotor. Then, shims of a certain thickness are placed on the timer stator fixture before the timer stator is placed in, and the concentricity of the timer stator is adjusted again with a micrometer. Only after both the timer stator and timer rotor are properly concentrically aligned can a test be performed. This entire installation process is cumbersome, requiring two separate dial indicator adjustments for concentricity, and each test takes half an hour. Furthermore, it demands a high level of skill from the installers.

[0004] Therefore, a rapid concentricity device for split-type circular time grids is needed, which can quickly position the mover and stator and ensure their concentricity. Summary of the Invention
