AI Technical Summary

Technical Problem

Existing traction mechanisms are prone to causing tubing deformation and wear when clamping tubing, failing to meet the precision requirements of diameter and width dimensions for precision medical devices.

Method used

The device employs a clamping design, which includes a first clamping arm and a second clamping arm driven by a clamping cylinder forming a V-shaped structure. The pipeline is axially positioned by positioning protrusions and limiting grooves, and radially fixed by applying pressure with fixed protrusions. Combined with a fine moving module and a linear module, it achieves high-precision pipeline clamping and movement.

Benefits of technology

It reduces the deformation and wear of pipelines during clamping, can adapt to the positioning requirements of pipelines of different diameters, and achieves high-precision pipeline processing.
