Embodiment Construction

[0023] like figure 1 As shown, a nut tightening machine control system includes a power supply and a touch screen, PLC and servo system respectively connected to the power supply. Control operation module, PLC is equipped with fault processing module and human-computer interaction module, PLC control is connected with worktable lifting mechanism, pulley tightening mechanism, sleeve mechanism, servo system is connected with tightening device, and PLC and servo system are connected with torque sensor. The PLC is also equipped with an alarm module, which is connected to the servo system through the fault processing module, and detects whether the clamping is in place through the PLC. If there is no clamping within the specified time, it will alarm. The human-computer interaction module is equipped with an emergency stop button. The emergency stop button controls the workbench lifting mechanism, pulley tightening mechanism, sleeve mechanism and tightening device through the PLC. ...

Abstract

The invention provides a screw cap screwing machine control system comprising a power supply and a touch screen, a PLC and a servo system which are connected with the power supply. The PLC is connected with the touch screen and the servo system. The touch screen is internally provided with a parameter setting module, a storage module and a control operation module which are interconnected. The PLC is provided with a fault processing module and a human-computer interaction module. The PLC is connected with a workbench elevating mechanism, a belt pulley tightening mechanism and a sleeve mechanism through control. The servo system is connected with a screwing device. A torque sensor is connected between the PLC and the servo system. Only the torque and the torsion angle are detected and analyzed so that the whole processing course is controlled and defective judgment and alarm processing are performed accordingly.

Description

technical field [0001] The invention belongs to the technical field of tightening machines, and in particular relates to a control system and a method for a nut tightening machine. Background technique [0002] At present, there are many types of pulley and nut tightening machines used in domestic automobile factories, and the control methods are also various. However, the accuracy of the tightening torque and angle often does not meet the production requirements, and the performance is not very stable. The failure rate remains high. In fact, the main reason for these problems is that the structure of the tightening machine control system is too complicated, the control method is cumbersome, the response speed is slow, the tightening torque is unstable, the tightening angle is not accurate, the equipment is bulky, and the maintenance is complicated. Without the upper computer, it cannot work. The corresponding price is also very expensive. [0003] A patent based on a CAN ...
