Finally, the third actuator 331 for controlling the locking assembly 33 operates to enable the locking assembly 33 to lock the guide rod 332, so as to prevent the car body, the chain 312 and the lifting plate 324 from being jacked up when the rear suspension spring is pressed, thereby ensuring the tensioning effect of the car body.

S4: and controlling the two axle mechanisms 7 to work so as to lift the brake disc of the lower swing arm rear suspension vehicle type to a preset height.

S5: the two compression assemblies 41 are controlled to move upward to press-fit the rear suspension spring to the spring pre-load position.

S6: after the rear suspension spring is pressed in place, the locking bolt of the rear suspension spring is locked by the screwing mechanism 5, then the detection mechanism 8 detects whether the fastening quality of the locking bolt of the rear suspension spring reaches the standard or not, and the next step is carried out after the fastening quality reaches the standard.

S7: the two axle mechanisms 7 are controlled to descend to the middle height position, and then the two compression assemblies 41 and the two axle mechanisms 7 are controlled to move downwards to be reset.

S8: the third driver 331 of each locking assembly 33 is controlled to release the guide rod 332, and then the second driver 321 of each lifting assembly 32 drives the lifting plate 324 to ascend, so that the chain 311 is in a loose state, and the hook 312 is conveniently released from the clamping relation with the vehicle body hanging point. The two hooks 312 are removed separately to allow each snap assembly 31 to release the vehicle body.

S9: controlling the first driving assembly 23 in the synchronizing mechanism 2 to ascend so as to separate the synchronizing mechanism 2 from the FDS linear body synchronizing block; after the synchronization mechanism 2 is separated from the FDS wire body synchronization block, the return drive mechanism 9 is controlled to descend and drive the apparatus back to the first position. During the return process, the second sensor 12 continuously detects and determines whether there is a human or object disturbance to protect the safety of personnel and equipment.

In other embodiments, for a vehicle body not belonging to the lower swing arm rear suspension vehicle type, in step S4, the axle mechanism 7 is controlled not to operate, then the swing arm locking bolts of the lower swing arm rear suspension vehicle type are tightened by the tightening mechanism 5, and then the detection mechanism 8 detects whether the fastening quality of each swing arm locking bolt is up to standard. And in step S6, before tightening the lock bolt of the rear suspension spring, the connection head of the tightening mechanism 5 is switched so that the tightening mechanism 5 can tighten the lock bolt of the rear suspension spring. It is thus clear that the rear overhang of this embodiment amasss the machine, its applicable swing arm rear overhang motorcycle type and do not belong to two kinds of automobile bodies of swing arm rear overhang motorcycle type down to screw up mechanism 5 and can be used for screwing up two kinds of locking bolt, and the suitability is high, and it is strong to use the flexibility, does benefit to reduction in manufacturing cost.

What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
