AI Technical Summary

Technical Problem

The existing pipe body clamping and centering device requires the coordinated action of multiple oil cylinders, resulting in high control accuracy requirements and low adjustment efficiency, which affects production efficiency.

Method used

It adopts a design that includes a base, guide rod, telescopic cylinder, clamping block and linkage gear. A telescopic cylinder drives the slide block and rack system to realize the coordinated movement of the two clamping blocks, reducing the reliance on multiple cylinders.

Benefits of technology

The clamping and loosening operations of the clamping block can be realized by controlling a telescopic cylinder, which improves the adjustment efficiency, reduces the control accuracy requirements, and simplifies the operation process.
