The working process of the screw assembly device for the automatic cell stack production line comprises the steps of installing a tightening gun 32 on a tightening gun support 13, connecting a shell 1 on a mechanical arm, enabling a Z-axis air cylinder 12 to drive the tightening gun support 13 to displace relative to a Y-axis moving frame 9 in the Z-axis direction, enabling the Y-axis moving frame 9 to move relative to a Y-axis plate in the Y-axis direction, enabling the Y-axis plate (namely an X-axis moving frame) to move relative to an X-axis support plate 4 (namely the shell 1) in the X-axis direction, namely enabling the tightening gun 32 to adjust relative to the mechanical arm in a three-dimensional space;
In a non-processing state, the X-axis locking pin 3 is inserted into the first positioning hole 7, the Y-axis locking pin is simultaneously inserted into the second positioning hole 11 formed in the Y-axis moving frame 9 and the Y-axis plate, the Z-axis air cylinder 12 does not work, and the tightening gun support 13 is in a locking state in three directions of the X-axis, the Y-axis and the Z-axis and is relatively fixed with the shell 1, so that the relative position relationship between the muzzle position of the tightening gun 32 and the mechanical arm is determined, and the mechanical arm can drive the device to move in space and drive the muzzle of the tightening gun 32 to move to a nut to be tightened;
After the tightening gun 32 moves in place, the Z-axis air cylinder 12 drives the tightening gun support 13 to move along the Z-axis direction, the muzzle position of the tightening gun 32 moves towards the direction of the workpiece, the tightening gun head 27 and the nut 30 form a connection relation, then the X-axis locking pin 3 and the Y-axis locking pin are recovered, the tightening gun 32 recovers the degree of freedom, and thus when the tightening gun 32 works, the tightening gun 32 moves in the X-axis direction and the Y-axis direction relative to the shell 1 (namely the mechanical arm) under the action of the reaction force, thereby absorbing the vibration and preventing the mechanical arm from being impacted;

During the screwing operation, the Z-axis buffer cylinder 15 is always kept pressure, so that when the screwing gun 32 bears impact force from the screwing gun head 27 and the workpiece 28 in the axial direction, the clamping jaw sliding plate 16 moves along with the impact force, and the impact force is counteracted by air pressure in the Z-axis buffer cylinder 15, so that the screwing gun 32 and the device are prevented from directly bearing rigid impact force.
