Displacement Tooling Design On Main Structure Of Heavy-vehicles High-strength-steel Car And Study Of Process Experimental

In this article, we proposed a positioner system to integrate this system with robot system based on the work station of stud welding robot with hybrid sources. The key point is the analysis and design of the robot-positioner system.This system is constituded by four parts:robot system, stud welding system, positioner system and electrical control system. Besides, the table tilt rotary device should meet the needs of analysis in selection and priciples of the control module according to the requirement, while the fixture is satisfied by the workpiece clamping.Taking the type of the positioner and the parameters of the rotation, such as torque, in to consideration, we calculated the main parts of the positioner, which is tilt gear, turbine, worm, tilt axis, the turbine shaft and worm shaft, and then selected, analyzed, checked all the right type to make a suitable match. Through experiment and testing, we regulated the coordinated motion of the positioner and simulated its behavior.Meanwhile, we analyzed the relationship between weld attitude and welding quality. The position movement before and after the positioner task complete is also analyzed by a position transform matrix, as well as the kinematic coupling and decoupling analysis.At last, we propose a solution to design the robot positioner workstation kinematic and simulation system. We welded stud with diameter016mm and022mmconducted on GY5、 GY4base material respectively by automatic control process and then analyzed the welding quality by shear strength and macroscopic fracture.
