Design and application of fully automatic double-shaft tightening machine for gear hub of locomotive based on machine vision

A fully automatic double-shaft tightening machine based on machine vision for gear hubs of locomotives is designed.The control of tightening torque of bolts is delivered by adopting the tightening process and torque control principle;relying on the adjusting mechanism of the lead screw,bolts of the gear hub with different specifications can be tightened;the machine vision is used to identify the bolt position and determine the initial position;the hardware composition and software system configuration of the control system of the fully automatic tightening machine are discussed,and the design flow of functions of error prevention and leakage prevention are described.The assembly accuracy and operation efficiency are levelled up,and the labor intensity of workers is reduced owing to the automatic bolt tightening machine.
