Description

Technical Field

[0002] The workpiece needs to be fixed with a pin before testing. The difficulty of fixing the pins of large-mass workpieces lies in their large size and heavy weight, which require large machines for processing and installation. The pins also require high precision, requiring sophisticated processing technology and technical support.

[0003] The traditional method of fixing with a pin usually utilizes a guide pin to forcibly twist the workpiece to assist in inserting the fixing column into the pin hole. Since some workpieces are heavy and the fixing pin holes are of different sizes, it is very easy to damage the edge of the pin hole while inserting the fixing column. It is also easy to cause obstructions during the subsequent removal of the fixing column. Some equipment requires multiple debugging before the pinning work can be performed. The operation is cumbersome and not conducive to rapid construction. Utility Model Content

Then, the first hydraulic column can be started again, and the first hydraulic column and the detection block can be pushed into the pin hole at the same time to complete the pin fixing work.
