Description

Technical Field

[0001] The utility model relates to the technical field of automobile manufacturing, in particular to a vehicle tire double-support arm mechanism. Background Art

[0002] The body underline support mechanism of the body underline process section (generally referred to as the "finishing line") generally uses telescopic forks to support the body chassis, and a pair of telescopic forks are equipped on both sides. However, the telescopic fork mechanism usually requires at least two stages of telescopic extension, and the mechanism itself is relatively complex. There is also a swing arm mechanism driven by a motor. After the swing arm is straightened, it is pushed to the body underline supporting chassis to receive the car and release the car to the conveying equipment of the finishing line. This kind of swing arm mechanism driven by a motor has a relatively high manufacturing cost. Therefore, it is necessary to design a new vehicle tire double support arm mechanism.

[0034] Principle of the utility model:

[0035] In actual application, the double supporting arm mechanism of the utility model is installed on the lift or the accompanying side jacking machine, and four groups are arranged corresponding to the positions of the four wheels. When the vehicle needs to be transferred, as the piston rod of the cylinder 2 slowly retracts, the push plate 3 also moves backward, and the bearing 44 of the supporting arm assembly 4 moves along the guide slope 32, and the double supporting arms rotate accordingly. When they are moved into place, the double supporting arms are in a closed parallel state, which is used to support the four tires of the vehicle. After the vehicle is transferred from the body hanger to the conveying plastic plate belt of the completion line via the lift or the accompanying side jacking machine, the piston rod of the cylinder 2 slowly pushes the push plate 3 forward, and the push plate 3 also moves forward, and the double supporting arms gradually open completely. At this time, the four tires of the vehicle all land on the conveying plastic plate belt of the completion line, and move forward with the plastic plate belt to the next step.
