Abstract
In order to achieve the common drilling and milling machine for friction stir joining (FSJ) , A model ZXTM-40 equipment is modified., it’s workstation transmission mode and axial direction press mode are mechanical transmission, through the modification, install stepper motors and drives , write program code ,PLC control the motor ,it can work to achieve Longitudinal automatic movement . the speed of workstation can input through the Interactive panel, the control system operate parameters to achieve semi-automated operation of equipment and overtravel protection.. In the vertical direction,install a sleeve on the handle, the sleeve has scale and recesses, it can control the pressure measurement of friction stir pin. weights hanged on the sleeve, research proves the optimum parameters are 3KG weights and 40CM away from the center, Workbench moving speed of 125mm/min, rotation speed of 730r/min, it can join 1mm thick 2024 aluminum by FSJ, appearance of bead is good.
