The pressing and resetting plate is then activated to generate an output at its output end, thereby lowering the plate in the longitudinal direction to press the gasket against the outer cover. Furthermore, the fourth gripper cylinder is activated to generate an output at its output end, thereby grabbing the bolts from the bolt conveyor and placing them on the front axle after the air-blasting and interpenetrating operation of the air-blasting and interpenetrating member.

[0112] S9. Assembly operation of bolts, gaskets, outer cover and front axle: turn on the fifth drive motor so that the output end of the fifth drive motor outputs, so as to drive the ninth electric cylinder to move in the front and rear directions; in addition, turn on the sixth slide rail so that the output end of the sixth slide rail outputs, so as to fine-tune the position of the front axle clamped by the fifth clamping cylinder, so that the front axle can be flipped sideways during assembly to reduce the insertion force when assembling the bolts; furthermore, turn on the translation cylinder so that the output end of the translation cylinder outputs, so as to drive the rotating clamping cylinder to move down to the top of the fifth clamping cylinder; finally, turn on the rotating clamping cylinder so that the output end of the rotating clamping cylinder outputs, so as to drive the bolts on the front axle to rotate, so as to remove the bolts from the gasket, outer cover and front axle in turn to complete the assembly of the front axle.
