Technical Field

The invention relates to the technical field of automobile design and manufacture, in particular to an assembly method of a strut upper support and an automobile body.

Background

Fig. 1 and 2 show a connecting structure for realizing a strut top mount and a vehicle body mount in the prior art. The alignment method is generally two types: A. the alignment is carried out manually during the assembly. This approach requires two additional operators, resulting in increased labor costs; the installation position space of the upper support of the sliding column and the vehicle body is narrow and remote, the visibility is poor, the operation is difficult, and the production beat is easy to delay. B. Before the chassis and the vehicle body are assembled, the sliding column is firstly installed on the vehicle body. The connecting structure needs to add two operators and corresponding auxiliary lifting equipment, so that the labor cost and the equipment cost are increased; the installation position space of the upper support of the sliding column and the vehicle body is narrow and remote, the visibility is poor, the operation is difficult, and the production beat is easy to delay.
