Then, the switch II is pressed to drive the air cylinder I202 to retreat, and the whole driving device 2 is pushed to rotate clockwise; when the inductor 2054 induces the equal-angle limiting groove 20511, the limiter driving cylinder 2052 is controlled to drive the limiter 2053 so that the limiting pin is clamped into the equal-angle limiting groove 20511, meanwhile, the cylinder I202 is driven to maintain the pressure, the welding robot starts to work, and the welding seam which can be welded at the current position is welded; after welding is finished, the limiter driving cylinder 2052 drives the limiter 2053 to enable the limiting pin to retreat, and the driving cylinder I202 continues to maintain the pressure state to enable the driving cylinder II 210 to be fixed at the current position; according to change over switch III, drive actuating cylinder II 210 stretches out (drive actuating cylinder I202 keeps stretching out the state) and promotes drive shaft 206 clockwise rotation, and when inductor 2054 sensed the constant angle spacing groove 20511, control stopper drive actuating cylinder 2052 drive stopper 2053 made stopper bayonet lock card advance constant angle spacing groove 20511, drive actuating cylinder II 210 pressurize state simultaneously, the initial condition is got back to the equipment, the piece is torn open.

The above working mode can be simplified as follows: clamping a mounting part, and driving the cylinder I202 to extend out for pressure maintaining (obtaining a first angle); on the basis of the first angle, driving the air cylinder II 210 to retreat for pressure maintaining (obtaining a second angle); driving the cylinder I202 to retreat for pressure maintaining (obtaining an angle III); on the basis of the third angle, the driving cylinder II 210 extends out for pressure maintaining, and the obtained angle IV is the same as the original position due to equal-angle rotation (if more rotation angles are needed, equal-angle limiting grooves 20511 can be equidistantly added) for resetting.
