Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of lifting appliance, especially relates to a wheel hub assembly lifting appliance. BACKGROUND

[0002] At present, the drive axle assembly assembly line is used for assembling wheel hub assembly on the axle tube of the axle housing, the wheel hub assembly is injected with gear oil after being assembled on the axle housing, the oil seal in the wheel hub assembly locks the lubricating oil in the wheel hub and prevents the gear oil from flowing out. When the wheel hub assembly is assembled on the axle housing, a lifting and pulling device needs to be used for cooperation. Because the lifting and pulling precision of the mechanical industry is not very high, the moving range of the up and down fine adjustment is large when the wheel hub assembly is lifted, and the wheel hub assembly will inevitably collide with the axle housing. If the wheel hub assembly is tilted during the collision, the oil seal lip may be knocked, reducing the sealing life of the oil seal. In recent years, the oil leakage fault of the oil seal is increasing year by year, and the claim amount is huge. The wheel hub oil seal leakage fault accounts for more than half of the oil seal leakage fault. Therefore, during the assembly of the wheel hub assembly, whether the lifting appliance can ensure the level during the assembly process is crucial to the improvement of the quality of the oil seal.

[0003] Industry status: the existing wheel hub assembly lifting appliance is divided into two categories: the first category is a flat plate structure, and this structure has no angle adjustment capability, so there is a problem of inclination during assembly; the second category is a step-selectable structure, and this structure reserves multiple hole positions for workers to select, but due to strength limitation, the distance between the hole positions is large, and the adjustment capability is insufficient. The above two lifting appliances are lifted by the wheel hub assembly wheel bolts.

[0004] Problems:

[0005] 1. The types of wheel hub assemblies commonly used by our company are as high as dozens, and the centers of gravity of different wheel hub assemblies are different.

[0006] 2. In order to prevent the wheel bolts from being scratched, the contact surface between the lifting appliance and the wheel hub assembly is made of brass. The brass bushing is thick and easy to wear. Considering the production cost, the brass bushing will be replaced only when one side is polished on a large area, so the brass bushing will be worn, the gap will be increased, and the inclination angle will be generated.

[0040] Working principle:

[0041] According to Figures 1 to 7As shown, the triangular lifting ring 1 is inclinedly slid along the rectangular through hole 16, and the height and gravity center of the triangular lifting ring 1 are changed during the sliding process. The depth of the adjusting bolt 6 inserted into the rectangular through hole 16 can change the sliding range of the triangular lifting ring 1 in the rectangular through hole 16 and the height of the upward sliding, so as to change the lifting center of the triangular lifting ring 1. The end of the limiting screw 8 at different positions is inserted into the rectangular through hole 16 to adjust the depth of the adjusting bolt 6 inserted into the rectangular through hole 16. When lifting the hub assembly, the brass bushing 10 is sleeved on the hub assembly wheel bolt, the hook 5 is fixed on the lifting plate 4 through the hex nut 13, so that the hook 5 can freely rotate but has certain resistance. After the brass bushing 10 is sleeved on the hub assembly wheel bolt, the hook 5 is rotated so that the lower end of the hook 5 is downward to prevent the hub assembly from falling during lifting. The triangular lifting ring 1 is connected to the lifting device, the center line of the triangular lifting ring 1 is the center line of the lifting device, the limiting screw 8 is inserted into the calculated position of the limiting hole (the position of the limiting hole is the position corresponding to the gravity center of the hub assembly of different models which is calculated in advance), the adjusting bolt 6 is rotated, the adjusting bolt 6 is inserted into the rectangular through hole 16 and quickly adjusted to the position that the end of the adjusting bolt 6 is in contact with the end of the limiting screw 8, the depth of the adjusting bolt 6 inserted into the rectangular through hole 16 is adjusted, the activity space of the triangular lifting ring 1 in the rectangular through hole 16 is changed, so that the center line of the triangular lifting ring 1 coincides with the gravity center of the hub assembly. The position of the limiting screw 8 is the theoretically calculated gravity center position of the hub, the adjusting bolt 6 can be quickly screwed to the specified position in the rectangular through hole 16 and limited by the limiting screw 8, and the excess limiting screw 8 can be screwed into the temporary storage hole 18 to prevent loss. Finally, the position of the adjusting bolt 6 is fine-tuned again so that the hub assembly is adjusted to be horizontal in the actual state. After long-term use of the brass bushing 10, the brass bushing 10 will be worn out and the hub assembly will have an inclination angle. At this time, the adjusting bolt 6 can be rotated to fine-tune the lifting center line of the triangular lifting ring 1 so that it is not coincided with the gravity center of the hub assembly, and an inclination angle in the opposite direction is generated to compensate for the inclination angle caused by the wear of the brass bushing 10. If the brass bushing 10 is seriously worn out, the hex head bolt 11 and the hex head nut 12 can be loosened to detach the lifting mechanism from the gravity center adjusting mechanism, that is, the lifting plate 4 is separated from the bent plate 2, so that the brass bushing 10 can be replaced.
