[0026] In summary, when using this locking nail device for workpieces, select the workpiece type, check whether the wrench is in position, whether the upper and lower rotation clamping cylinders 4 are loosened, and whether the bit 31 is in the retracted position. The operator places the screw into the bit 31 of the bit 31, places the corresponding workpiece type support and the rotating arm, and the workpiece is placed in the correct position. At the same time, when the displacement sensor 33 detects that the length of the rivet is within the range value, the green light is on, otherwise the red light is on and the program is locked, and it cannot be executed even if the start switch 11 is pressed. Place it back in the correct position or replace the rivet within the range value, and the green light is on. The safety light curtain has no obstruction and can be operated. The set value of the displacement sensor 33 can be adjusted on the screen. Press the start button with both hands, and the corresponding upper and lower rotation clamping cylinders 4 clamp the workpiece, and the clamping in-position switch lights up. In case of an emergency, the emergency stop switch 13 can be pressed, and the upper and lower rotation clamping cylinders 4 will automatically loosen. After the fault is processed, the emergency stop is reset, and press the start switch 11 with both hands again. After the workpiece is clamped, hold the pneumatic wrench 30 and move it downward. When the screw contacts the workpiece, the wrench continuously applies a slight downward force, and the wrench switch is triggered to rotate automatically. Note that the selected rotation direction is positive rotation. After the nail is inserted in place, lift the wrench and it will automatically stop rotating. Release the balancer 26 and it will automatically bring the wrench back to its original position. Pick up the torque in-position switch 6 and the torque wrench 7 to calibrate the torque. At this time, the wrench in-position switch will be triggered. When the torque in-position switch 6 and the torque wrench 7 are placed back, it is detected that the wrench is in position, and the upper and lower rotation clamping cylinders 4 automatically loosen, and the loosening detection is in place. The working light turns yellow and enters the standby state, and enters the next working cycle.
