Description

Technical Field

[0001] This invention relates to the field of automobile manufacturing technology, specifically to a servo press-fit plug rod deformation compensation detection and adjustment component and its compensation method. Background Technology

[0002] The most common method for pressing the cylinder block and cylinder head cup plug of automobile engine is to use servo positioning to drive the press rod and press head. The advantage of this pressing method is that the cost is relatively low.

[0003] However, in practical applications, when using servo positioning to drive the pressure rod and pressure head to press the cup-shaped plugs, if multiple cup-shaped plugs have the same pressing depth requirement but different pressing forces, the pressing force will cause longitudinal mechanical deformation of the pressure rod at the micro level. This longitudinal mechanical deformation directly affects the actual pressing depth and is prone to problems of unstable pressing depth, thus posing a hidden danger to production quality. Summary of the Invention

[0004] The purpose of this invention is to provide a servo press-fit plug rod deformation compensation detection and adjustment component and its compensation method to solve the problems mentioned in the background art.
