AI Technical Summary

Problems solved by technology

[0002] During the production process of the oil cylinder, there is a high requirement for the coaxiality of the left and right ends of the cylinder barrel. For a longer cylinder barrel, deformation, ellipse or left and right misalignment are more likely to occur during production.

Therefore, in the production process, it is necessary to detect the coaxiality of the cylinder. Most of the existing methods are manual visual inspection, the detection rate is low, and the detection has been missed.

There is also a method of using the left and right ends of the plug gauge for plugging, but the detection is cumbersome, the workload is heavy, and the specific data of the deformation cannot be read out, which is not convenient for analysis

[0003] The important thing is that the detected cylinders with poor coaxiality are basically discarded at present. If they can be corrected, the pass rate will be greatly improved and the production cost will be reduced.
