[0031] During vehicle production, brake discs and shock absorbers need to be assembled. Before installing the shock absorber onto the brake disc, the fastening nuts at the ends of the shock absorber need to be tightened first. In actual operation, researchers found that tightening the fastening nuts at the ends of the shock absorber, which is currently done manually, is inefficient and increases the labor intensity of workers.

[0032] The utility model provides a tightening mechanism and an assembly device, aiming to solve the technical problem of low work efficiency in tightening a fastening nut at the end of a shock absorber.

[0033] See also Figure 1In one embodiment of the present invention, the tightening mechanism includes a mounting frame 100, a clamping assembly 200 and a tightening assembly 300; the clamping assembly 200 is arranged on the mounting frame 100 and is used to clamp the shock absorber 610, the tightening assembly 300 is arranged on one side of the clamping assembly 200, and the tightening assembly 300 includes a tightening gun 310 and a driving member 320; the driving member 320 can drive the tightening gun 310 to move in a direction close to the clamping assembly 200, so that the gun head of the tightening gun 310 is sleeved on the fastening nut.

[0034] The present invention utilizes a clamping assembly 200 and a tightening assembly 300 to replace manual tightening of the damper 610's fastening nut, thereby improving work efficiency and reducing labor intensity. In this embodiment, the clamping assembly 200 is used to clamp the damper 610, securing its position and preventing it from rotating with the fastening nut when tightened by a tightening gun 310. The tightening assembly 300 includes a tightening gun 310 and a driver 320. The driver 320 is capable of driving the tightening gun 310 toward the clamping assembly 200, causing the gun head of the tightening gun 310 to fit over the fastening nut. The driver 320 can then drive the tightening gun 310 to rotate and tighten the fastening nut. Furthermore, the driver 320 can also drive the tightening gun 310 away from the clamping assembly 200, disengaging the gun head of the tightening gun 310 from the fastening nut to facilitate transport of the damper 610 to the next process. Specifically, when tightening the fastening nut of the shock absorber 610, the clamping assembly 200 first clamps the shock absorber 610 to fix the position of the shock absorber 610; then, the driving member 320 drives the tightening gun 310 to move toward the clamping assembly 200, and the gun head of the tightening gun 310 is placed on the fastening nut; finally, the tightening gun 310 is controlled to operate, and the tightening gun 310 drives the fastening nut to rotate to tighten the fastening nut. This tightening mechanism clamps the shock absorber 610 by the clamping assembly 200, drives the tightening gun 310 to move by the driving member 320, causes the gun head of the tightening gun 310 to be placed on the fastening nut, and then drives the fastening nut to rotate by the tightening gun 310 to tighten the fastening nut of the shock absorber 610. This can replace manual tightening of the fastening nut of the shock absorber 610, improve work efficiency, and also reduce the labor intensity of workers. This tightening mechanism is applied to the field of vehicle production technology.

After the fastening nut of the shock absorber 610 is tightened, the driving member 320 is first controlled to drive the mounting seat 330 to move away from the clamping assembly 200, thereby driving the tightening gun 310 to move away from the clamping assembly 200; then the clamping assembly 200 is controlled to release the shock absorber 610, at which point the shock absorber 610 can be transported to the next process by an external transport robot. In a specific embodiment, the driving member 320 can be a driving cylinder or a driving oil cylinder, the structure of the tightening gun 310 can refer to the existing electric tightening gun 310, and the tightening gun 310 is provided with a tightening sleeve adapted to the fastening nut.

[0039] See also Figure 2 In one embodiment of the present invention, the clamping assembly 200 includes a driving body 210 and two clamping blocks 220 spaced apart from each other on the driving body 210. The driving body 210 is disposed on the mounting frame 100, and the driving body 210 can drive the two clamping blocks 220 to move toward or away from each other. In this embodiment, the driving body 210 can drive the two clamping blocks 220 to move toward each other to clamp the shock absorber 610, and the driving body 210 can also drive the two clamping blocks 220 to move away from each other to loosen the shock absorber 610. In a specific embodiment, the driving body 210 can be a bidirectional drive cylinder, and the two clamping blocks 220 are each formed with an arcuate surface on one side facing each other, and the arcuate surface matches the outer surface of the shock absorber 610.

[0040] See also Figure 2 In one embodiment of the present invention, a positioning plate 230 is provided above the clamping block 220. The positioning plate 230 is provided with a positioning slot 231 for accommodating the shock absorber 610. Specifically, when the clamping assembly 200 clamps the shock absorber 610, it is first necessary to control the driving body 210 to drive the two clamping blocks 220 to move away from each other, thereby increasing the distance between the two clamping blocks 220 to provide sufficient space for the shock absorber 610 to be placed. Subsequently, the shock absorber 610 is placed between the two clamping blocks 220. When the shock absorber 610 is placed between the two clamping blocks 220, the shock absorber 610 is first placed in the positioning slot 231 of the positioning plate 230. Finally, the driving body 210 is controlled to drive the two clamping blocks 220 to move toward each other, thereby clamping the shock absorber 610. The provision of the positioning slot 231 enables the shock absorber 610 to be pre-positioned to ensure that the position of the shock absorber 610 is accurate.

[0041] See also Figure 3In one embodiment of the present invention, the tightening mechanism further includes a locking assembly 400, which includes a positioning pin 410 and a locking unit 420. The locking unit 420 is formed with an avoidance groove 423, in which the positioning pin 410 is accommodated, and the positioning pin 410 can be inserted into the mounting hole of the shock absorber 610. In this embodiment, the clamping assembly 200 is used to clamp the middle portion of the shock absorber 610, and the locking assembly 400 is used to clamp the end portion of the shock absorber 610. Through the cooperation of the clamping assembly 200 and the locking assembly 400, the position of the shock absorber 610 can be better fixed. Specifically, the locking unit 420 is used to clamp the end portion of the shock absorber 610, and the positioning pin 410 can be inserted into the mounting hole at the end portion of the shock absorber 610 to prevent the shock absorber 610 from rotating. The avoidance groove 423 is used for the positioning pin 410 to pass through to avoid interference between the positioning pin 410 and the locking unit 420. In a specific embodiment, the diameter of the positioning pin 410 is slightly smaller than the diameter of the mounting hole at the end of the shock absorber 610, and the difference between the two diameters is 0.1 mm.

[0042] See also Figure 3 In one embodiment of the present invention, the locking unit 420 includes a driving unit 421 and two locking blocks 422 spaced apart from the driving unit 421.
