[Abstract]:This subject is a research and development project entrusted by the enterprise. In this paper, multi-axis automatic tightening is studied, and a multi-axis automatic tightening device for globe valve is designed and developed. Firstly, the design idea, composition and software method of multi-axis automatic tightening device are described. The design scheme of multi-axis automatic tightening device is presented, which includes control unit, drive unit, rotary unit and gas path unit. The function of the control unit is to coordinate each driving unit to complete the tightening action and to measure the torque and rotation angle. The function of the drive unit is to complete the tightening action according to the control unit instruction. The function of the rotary unit is to realize the automatic rotation of the turntable according to the command of the control unit. The function of the air path unit is to provide the power output for the cylinder in the air path. Secondly, the control unit, drive unit, rotary unit and gas path unit are introduced in detail. The control unit adopts the control scheme with PLC as the core, realizes real-time display and parameter setting through man-machine interaction, and communicates with the drive unit through serial port. The drive unit is mainly composed of servo system, reducer and torque sensor. The rotary unit consists of a step motor and a turntable. The air path unit consists of different types of cylinders. Finally, the fuzzy PID control algorithm is applied to the synchronous control of multi-motor, and the valve cap and the punching valve cap are tightened at the same time. Through a large number of experiments and analysis, it is concluded that the tightening result is stable and the precision of the final tightening torque meets the design requirements.
