Abstract

A screw locking type antifriction-driven linear positioning cylinder and a control method thereof are provided to solve the problems of low positioning accuracy and complex structural assembly of the current linear positioning cylinder. The present invention is composed of end cover I, cylinder barrel, end cover II, lead screw locking mechanism, piston mechanism and piston rod. It is on the end cover II and threaded with the piston rod after passing through the piston mechanism. The piston mechanism is placed in the cylinder and fixedly connected with the piston rod. The piston rod passes through the end cover I and moves synchronously with the piston mechanism. The invention adopts the built-in screw locking mechanism to realize the precise locking and positioning of the piston rod at any position, which not only inherits all the good characteristics of the basic structure of the existing linear cylinder, but also solves the problems caused by the complex structure of the existing locking cylinder. It has good engineering application value in the technical fields of semiconductor processing, automatic measurement and control, robot drive and other technical fields due to problems such as reduced sealing performance and difficult production.
