These movable parts are cylinders, which can make full use of the existing high-pressure gas pipelines in the workshop, and the cylinders have the advantages of fast response speed and good working stability during the working process.

Preferably, the lifting guide rail of the yoke is provided with a clamping cylinder for clamping the yoke. The clamping cylinder can keep the fork on the running frame stably, effectively prevent the vehicle body from moving due to the instability of the yoke, and improve the safety of the vehicle body in the process of being transported and processed.

Preferably, a support rod connecting the two is provided between the yoke lifting guide rail and the traveling frame. The provided support rod can increase the firmness of the yoke lifting guide rail on the walking frame, and improves the stability of the walking frame in the working process.

Preferably, the support rod is a split structure, which includes two connecting rods at its two ends and a pipe column at the middle position, and one end of the two connecting rods is respectively hinged with the yoke lifting guide rail and the walking frame , and the other end is threadedly connected with the two ends of the string respectively. Such a structure of the support rod can make it connect the yoke lifting guide rail and the walking frame very stably, and it is convenient for the support rod to be arranged between the yoke lifting guide rail and the walking frame.

Therefore, the beneficial effects of the utility model:

1. Since the vehicle body assembly off-line device is working, the body is held up by the yoke, and the body has high stability on the yoke, which improves the safety of the body when being transported and operated.

2. Due to the high stability of the body on the wishbone, the body is not prone to rollover during the transfer process, and it is not easy to collide with each other, which ensures the appearance quality of the body.

3. The vehicle body assembly off-line device occupies a small space, which is convenient to meet the work requirements of some old-fashioned automobile production lines.

4. The vehicle body assembly off-line device only utilizes the transmission mechanism provided on itself in the working process, and these transmission mechanisms are convenient for maintenance, and the failure rate in the working process is low.
