[0030] Working principle: Place the workpiece that needs to be screwed in the placement slot 7, so that the placement slot 7 fixes the position and angle of the workpiece, control the main machine 8 to control the rotary cylinder 2 and the telescopic cylinder 3, so that the rotary cylinder 2 works, and the telescopic cylinder 3 drives the pressing plate 4 to move to the top of the workpiece, and makes the positioning hole 5 of the pressing plate 4 correspond to the position of the axis on the workpiece, and at the same time, the operation of the rotary cylinder 2 will drive the connecting plate 13 to move to the inner wall of the middle part of the positioning frame 14, so that the through hole 16 is aligned with the position of the limit hole 19, and the telescopic cylinder 3 works to drive the pressing plate 4 to move downward, so that the pressing plate 4 is pressed on the workpiece, and the positioning hole 5 is sleeved on the axis of the workpiece, so that the pressing plate 4 cooperates with the positioning hole 5 to press and fix the workpiece, and at the same time, the operation of the telescopic cylinder 3 will drive the detection rod 12 is inserted into the limiting hole 19, and the detecting rod 12 passes through the limiting hole 19 and is inserted into the through hole 16. When the detecting rod 12 is inserted into the through hole 16, the sensing contact piece 15 contacts the outer surface of one end of the sensing contact 17 and pushes the sensing contact 17 to swing, so that the sensing contact 17 pushes the telescopic rod 20 to contract and squeezes the first spring 21. At the same time, the thrust of the first spring 21 pushes the sensing contact 17 through the telescopic rod 20, so that one end of the sensing contact 17 stably contacts the side of the sensing contact piece 15, so that the sensing contact piece 15 and the sensing contact 17 are in contact and electrically connected. The detecting rod 12 continues to move downward until the sensing contact piece 15 contacts the pressure touch sensor 18, so that the sensing contact piece 15 and the pressure touch sensor 18 are in contact and electrically connected. A contact electrical connection is made, and the pressure-touch sensor 18 transmits a signal to the control host 8. The control host 8 determines whether the pressure plate 4 moves to the specified position to press and fix the workpiece through the contact electrical connection between the sensor contact piece 15, the sensor contact 17 and the pressure-touch sensor 18. Then the control host 8 supplies power to the electric screwdriver 9, takes the electric screwdriver 9 out of the placement ring 30, moves the electric screwdriver 9 to the top of the screw hole designated for screwing according to the avoidance hole 6, aligns the socket 28 with the plug rod 29, pushes the electric screwdriver 9 to move downward, inserts the plug rod 29 into the socket 28, and pushes the locking frame 24 upward inside the limit frame 23. At the same time, when the locking frame 24 moves upward, it squeezes the second spring 27, so that the locking frame 24 moves downward The side middle cavity moves to the side of the limit block 25, so that the locking frame 24 releases the restriction on the movement position of the limit block 25 and the push switch 22, and pushes the electric screwdriver 9 to move downward, driving the screwdriver head 11 to drive the screw into the screw hole, and pressing the push switch 22 to start the electric screwdriver 9. The output shaft of the electric screwdriver 9 drives the screwdriver head 11 to rotate through the torque detection sensor 10, so that the screwdriver head 11 drives the screw to be screwed into the screw hole. At the same time, the torque detection sensor 10 detects the torque of the screw until the torque of the screw meets the requirements, and transmits the data to the control host 8, records the qualified torque and the qualified number of torque, and the electric screwdriver 9 performs the next screw driving work according to the avoidance hole 6 until the qualified number of screw driving torque recorded by the control host 8 meets the requirements.Insert the electric screwdriver 9 into the placement ring 30, store the electric screwdriver 9, control the main machine 8 to work, drive the telescopic cylinder 3 and the rotary cylinder 2, make the telescopic cylinder 3 extend upward, drive the pressing plate 4 to move upward, release the pressing and fixing of the workpiece, and at the same time pull the detection rod 12 out of the through hole 16 and the limit hole 19, then the rotary cylinder 2 works, drives the telescopic cylinder 3 and the pressing plate 4 to rotate, moves the pressing plate 4 away from the top of the workpiece, and drives the connecting plate 13 to move out of the positioning frame 14, and removes the workpiece placed on the placement slot 7.
