The same operation locks the first Y-directional moving unit 22 at the second fixed position.
In this embodiment, the first Z-direction compressing unit 23 is fixed to the sliding plate 221 of the first Y-direction moving unit 22. The first Z-direction compressing unit 23 specifically includes a first guide shaft 233, a first fixing sleeve 231, a first sliding sleeve 235, a first floating plate 232, and a first spring 234. The first floating plate 232 and the sliding plate 221 are disposed in parallel, and 2 sets of through holes are formed in the first floating plate 232 and the sliding plate 221, respectively. The number of the first sliding sleeves 235 is 2, and the first sliding sleeves are respectively vertically fixed at the position of the through hole of the sliding plate 221. The first fixing sleeve 231 is provided with 2 fixing sleeves, which are vertically fixed at the positions of the through holes of the first floating plate 232, respectively, and the first fixing sleeve 231 and the first sliding sleeve 235 are coaxially arranged. The first floating plate 232 is connected to the sliding plate 221 in a floating manner by a first spring 234, one end of which abuts against the sliding plate 221 and the other end of which abuts against the first fixing sleeve 231.

The first guide shaft 233 is set to have a fixed end at the side connected to the first holder 231 and a movable end at the side connected to the first end cap 236, with the first guide shaft 233 extending between the fixed end and the movable end. The first sliding sleeve 235 has a barrel-shaped structure, and an end thereof away from the sliding plate 221 is provided with a first stepped hole 239, and when the first guide shaft 233 moves to a certain distance, the first end cap 236 is caught in the first stepped hole 239, which is the highest position of the first guide shaft 233.
Further, a second self-locking type rotary plunger a237 is further disposed on the first sliding sleeve 235, and a first limit groove is correspondingly disposed on the first end cover 236. When locking is required, the second self-locking rotary plunger a237 is screwed, and the movable pin is extended and inserted into the first stopper groove to restrict the Z-direction movement of the first guide shaft 233, thereby restricting the Z-direction movement of the first support unit 21 connected to the first Z-direction compression unit 23.
The first spring 234 is a compression spring, and is pre-compressed when installed. In the free state, the first floating plate 232 may be at the uppermost position by the force of the first spring 234, and at this time, the first end cap 236 may be caught at the step of the first stepped hole 239 of the first sliding sleeve 235 to limit the Z-direction uppermost position of the first floating plate 232. The second self-locking type rotary plunger a237 is then screwed so that the movable pin is protruded and inserted into the first catching groove, to catch the first floating plate 232 at the uppermost position. The second self-locking type rotary plunger a237 is unscrewed to disengage the movable pin from the first stopper groove, and at this time, the first floating plate 232 moves downward by the external Z-direction force until the lower plane of the first floating plate 232 contacts the upper plane of the sliding plate 221. During assembly, the distance between the first floating plate 232 and the sliding plate 221 is strictly controlled, on one hand, the compression amount of the first spring 234 is limited, and the distance between the first floating plate 232 and the sliding plate 221 is far smaller than the allowable compression amount of the first spring 234, so that the first spring 234 is prevented from being damaged and failing due to over-compression. On the other hand, the distance between the first floating plate 232 and the sliding plate 221 is set to ensure that the front suspension assembly is in the theoretical assembly position when in contact with the vehicle body, so as to prevent the assembly from being out of assembly.
In this embodiment, the first supporting unit 21 includes 4 first Z-direction supports 211 and 1Y-direction limiting plate 212, and the 4 first Z-direction supports 211 are fixed on the upper surface of the first floating plate 232 of the first Z-direction compressing unit 23 for positioning and supporting the brake disc assembly. The Y-direction limiting plate 212 is fixed to the lower surface of the first floating plate 232, and the Z-direction limiting plate does not contact the rear brake disc assembly. In the assembling process, the rear brake disc assembly is connected with the rear axle frame through the connecting rod due to the structure of the vehicle, and the motion trail of the rear brake disc assembly does circular motion around the axis of the connecting rod and the axis of the rear axle connecting joint. The rear brake disc assembly moves in the Z direction with a concomitant Y movement. The Y-direction limiting plate 212 is used for limiting the rear brake disc assembly in the Y-direction, that is, when the rear brake disc assembly moves in the Y-direction, preventing the first supporting unit 21, the first Z-direction compressing unit 23 and the first Y-direction moving unit 22 from falling off along with the Y-direction movement, and further avoiding the rear brake disc assembly from being separated from the first supporting unit 21.
Referring to fig. 6 to 8, in the present embodiment, the second floating support mechanism 3 includes a second support unit 32, a second Z-direction compression unit 33, and a second fixed plate 31. The second support unit 32 is fixed to the second Z-direction compression unit 33, the second Z-direction compression unit 33 is floatingly coupled to the second fixing plate 31, and the second fixing plate 31 is fixed to the pre-stack tray 4.

The second floating plate 332 is disposed parallel to the second fixed plate 31, and 2 sets of through holes are formed in the second floating plate 332 and the second fixed plate 31, respectively. The number of the second sliding sleeves 335 is 2, and the second sliding sleeves are respectively vertically fixed at the position of the through hole of the second fixing plate 31. The second fixing sleeve 331 is provided with 2, and is vertically fixed at the position of the through hole of the second floating plate 332, and the second fixing sleeve 331 and the second sliding sleeve 335 are coaxially arranged. The second floating plate 332 is connected to the second fixed plate 31 by floating through a second spring 334, one end of the second spring 334 abuts against the second fixed plate 31, and the other end abuts against the second fixed sleeve 331. The second guide shaft 333 is sleeved in the second sliding sleeve 335 through two sets of linear bearings B338, passes through the second spring 334, and has one end fixedly connected with the second fixing sleeve 331 through a screw and the other end fixedly connected with the second end cap 336 through a screw. The second guide shaft 333 is directly extended at the fixed end and the movable end, and the connecting side with the second end cap 336 is set as the fixed end and the movable end of the second guide shaft 333. The second sliding sleeve 335 has a barrel-shaped structure, and an end thereof away from the second fixing plate 31 is provided with a second stepped hole 339, and when the second guide shaft 333 moves to a certain distance, the second end cover 336 is locked in the second stepped hole 339, which is the highest position of the second guide shaft 333.
It should be noted that the first guide shaft 233 and the second guide shaft 333, and the first spring 234 and the second spring 334 in the present embodiment have the same structure, but have different dimensions, and the lengths and diameters of the first guide shaft 233 and the second guide shaft 333, and the specifications of the first spring 234 and the second spring 334 are calculated according to the specific structures and stress conditions of the front axle damper spring and the rear axle damper spring, respectively, so that there is a difference. The second sliding sleeve 335 has the same structure and dimensions as the first sliding sleeve 235, the second fixing sleeve 331, the first fixing sleeve 231, the second end cap 336 and the second end cap 336, the second sliding sleeve 335 is also provided with a second self-locking rotary plunger B337, and the second end cap 336 is correspondingly provided with a limiting groove. When locking is required, the second self-locking type rotary plunger B337 is screwed, and the movable pin is protruded and inserted into the second limiting groove to limit the Z-directional movement of the second guide shaft 333, thereby limiting the Z-directional movement of the second supporting unit 32 connected to the second Z-directional compression unit 33.
In this embodiment, the second support unit 32 is attached to the second floating plate 332 of the second Z-direction compressing unit 33. The second support unit 32 includes 3 second Z-direction supports 321 for supporting and positioning the front brake disc assembly.

The second self-locking type rotary plunger B337 is then screwed such that the movable pin is protruded and inserted into the catching groove to catch the second floating plate 332 at the uppermost position. The second self-locking rotary plunger B337 is unscrewed to disengage the movable pin from the second limiting groove, and at this time, the second floating plate 332 is driven to move downward by the external Z-direction acting force until the lower plane of the second floating plate 332 contacts the upper plane of the second fixed plate 31. During assembly, the distance between the second floating plate 332 and the second fixed plate 31 needs to be strictly controlled, on one hand, the compression amount of the second spring 334 is limited, and the distance between the second floating plate 332 and the second fixed plate 31 is far smaller than the allowable compression amount of the second spring 334, so that the second spring 334 is prevented from being damaged and failing due to over-compression of the second spring 334. On the other hand, the distance between the second floating plate 332 and the second fixed plate 31 is set to ensure that the rear shock-absorbing spring is in a theoretical assembly position when contacting with the vehicle body, so that the rear shock-absorbing spring is prevented from being incapable of aligning with a vehicle body fitting column, and the shock-absorbing spring is prevented from collapsing to damage personnel and equipment.
The aforesaid is the concrete structure that the brake disc floating support closed the tray system together, during the assembly, will the aforesaid close the tray system at production line conveyor and carry to closing before the frock station, assemble the vehicle chassis part on closing the tray earlier.
During assembly, attention needs to be paid to: the second Z-direction compression unit 33 is locked by the second self-locking type rotary plunger B337 before the front brake disc assembly is mounted to prevent the second support unit 32 from floating in the Z-direction. Before the rear brake disk assembly is mounted, the first Z-direction compression unit 23 is locked by the second self-locking type rotary plunger a237 to restrict the first support unit 21 from floating in the Z-direction. Then, the first Y-directional moving unit 22 of the first floating mechanism is moved outward to the second fixed position, and the first Y-directional moving unit 22 is locked by the first self-locking type rotary plunger 242, at which time the rear brake disk assembly is placed. The purpose of this cloth operation is to avoid interference of the rear brake disc assembly with other parts of the vehicle. After the rear brake disk is set, the first self-locking type rotary plunger 242 is unscrewed to release the Y-direction lock of the first support unit 21, and then the first Y-direction moving unit 22 is moved inward to the first fixed position and locked by the first self-locking type rotary plunger 242. The first fixed position is a theoretical assembly position where assembly of other vehicle components to the rear brake disc assembly is performed.
After all the vehicle chassis parts are assembled on the mounting tray and before the vehicle chassis parts are ready to enter the mounting station, the second self-locking rotary plunger a237 of the second floating mechanism is unscrewed to unlock the second support unit 32 in the Z direction and float the second support unit 32 in the Z direction. At the same time, the second self-locking rotary plunger B337 of the first floating mechanism is unscrewed to unlock the first support unit 21 from the Z-direction, and the first support unit floats in the Z-direction. Finally, the first self-locking rotary plunger 242 of the first fixing unit 24 is unscrewed to unlock the first supporting unit 21 from the Y-direction, and the first supporting unit 21 moves in the Y-direction.
At this time, the second supporting unit 32 may float in the Z direction, and the first supporting unit 21 may float in the Z direction and the Y direction. The loading tray can enter the loading station to carry out loading operation with the vehicle body.
When assembled, the first and second springs 234 and 334 are preferentially compressed, and compression of the vehicle damper springs is avoided, since the first and second springs 234 and 334 have a lower modulus of elasticity than the vehicle damper spring. Because the elastic modulus of the first spring 234 and the second spring 334 is small, the force generated after being compressed is not enough to overcome the self-gravity of the vehicle body, so that the vehicle body cannot be jacked up to be separated from the hanger. The position of the vehicle body is ensured without complex equipment, so that the structure of the tray assembling system is simplified, the cost of the vehicle assembly production line is greatly reduced, and the failure rate is low because each component part has a simple structure and does not have complex equipment. And after the fault occurs, the factors influencing the fault are few, and the troubleshooting processing time is short, so the production efficiency of the production line can be improved.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can substitute or change the technical solution of the present invention and the inventive concept within the technical scope of the present invention.
