The model of described PLC:Siemens PLC/224XP, the PLC are whole control systems Core, pass through I/O port or connection and receive external signal, carry out logical operation, control scroll chuck, stepper motor, servo electricity The action of machine.
The model of described touch-screen:The refreshed TPC7062TX in the Kunlun, the touch-screen mainly realize the friendship of man-machine interface Mutually, whole system operational factor, including servomotor output torque, stepper motor speed and its stroke are set by it.
Described stepper motor driver model:HBS860H, it is mainly used to Driving Stepping Motor operation.
Described stepper motor model is:86HBS85, the fortune of straight line up and down of the stepper motor major control servomotor It is dynamic.
Described motor servo driver model:Delta ASD-B2-0421-B, it mainly drives the operation of servomotor And moment of torsion control.
Described servo motor model number is:Delta ECMA-C20604RS, its rotary shaft are connected by shaft coupling and monkey wrench Connect, by the rotation of motor, realize screwing for bolt, and being precisely controlled for bolt and its fixed sleeve moment of torsion can be realized.
For described scroll chuck to be pneumatically scroll chuck, scroll chuck center is in same center with monkey wrench center On line.
Described proximity switch is PNP proximity switches, model LJ12A3-4-Z/EY, is mainly used in monitoring system reset When, whether equipment returns to original position.
One kind provided by the invention screws torsion system automatically, and its system core is controlled with PLC, be reliable and stable, operation letter It is single, coordinate the human-computer interaction interface of touch-screen, it can realize the Automated assembly of different size bolt and its adapter sleeve, and it is filled With moment of torsion Serve Motor Control, being precisely controlled for assembling torque value is realized, reduces the work of worker's repeatability, improves Operating efficiency, production cost is saved.

Embodiment
Torsion control system is screwed automatically to one kind of the present invention below in conjunction with the accompanying drawings to be further detailed:One Kind screws torsion control system, including PLC automatically(1), scroll chuck air valve(2), stepper motor driver(3), watch Take motor driver(4), scroll chuck(5), stepper motor(6), servomotor(7), touch-screen(8), proximity switch(9), peace Full raster(10), starting switch(11), pressure switch(12), PLC is connected by IO control lines with scroll chuck air valve, Scroll chuck air valve is connected by tracheae with scroll chuck cylinder, and PLC is connected by connection and stepper motor driver Connect, stepper motor driver is connected by connection with stepper motor;PLC passes through connection and motor servo driver Connection, the data-signal of motor servo driver feed back to PLC by feedback signal line, and motor servo driver passes through Connection is connected with servomotor, and the signal of servomotor feeds back to motor servo driver by feedback signal line;PLC is controlled Device is connected by connection with touch-screen, and touch-screen feeds back to PLC by feedback signal line;Proximity switch, safety light Signal is fed back to PLC by grid, starting switch, pressure switch by IO control lines.
When being operated, press battery main switch, control system obtain it is electric, according to the size of assembling product on the touchscreen Set moment of torsion, speed, travel parameters and set clamp pressure size(If clamp pressure is less than switch setting pressure, that System will not work), first operation presses reset key, allows system reset, and equipment enters holding state, then by bolt and It is placed on after several teeth of adapter sleeve hand fit on scroll chuck, presses start key, system starts automatic running, automatic clamping fastener Set, monkey wrench leading portion quickly run downwards, back segment slow running are entered close at bolt head, makes monkey wrench and outer-hexagonal spiral shell Bolt head coordinates, and servomotor starts to rotate after coordinating in place.Monkey wrench screws bolt under the drive of servomotor(Moment of torsion reaches It is defined to setting value), after assembling in place, scroll chuck unclamps, and worker's pickup, system automatically resets, you can is filled next time Match somebody with somebody.
After equipment startup in normal course of operation, if someone or foreign matter enter working region(Safe grating detects Foreign matter, feed back signal to PLC), then equipment will be unconditional out of service, prevent contingency.
