Abstract

A precision inchworm motor for micro-pipe detection provided by the present invention is characterized in that it includes a driving mechanism and a clamping mechanism 1 and a clamping mechanism 2 located on the front and rear sides of the driving mechanism, and is driven by the driving mechanism under the action of the driving current 1. Clamping mechanism one advances, and the driving mechanism drives clamping mechanism two to advance. The present invention designs a precision inchworm linear motor for micro-pipe detection based on the principle of inchworm motion by means of intelligent material drive technology and compliant mechanism technology. In order to facilitate the clamping mechanism to clamp the inner wall of the pipeline, a symmetrical four-compliant claw is designed to achieve the clamping function with interference fit; the driving mechanism uses an intelligent material actuator and a compliant spring design with an annular groove to realize Reset function after end of precession. The invention can realize operations such as defect detection and load handling under the requirement of micro-nano scale precision, and can also provide a reference scheme for in vivo detection in the field of biomedicine.
