Description

The present invention relates to a method of assembling a vehicle component, and more particularly to a method for assembling a shroud frame having a shroud door separated from a vehicle body and a stay extending downward from the shroud door. The present invention relates to a method for assembling vehicle parts to which machines are assembled.

(Prior Art) As is well known, vehicles such as automobiles are assembled by assembly work on a vehicle assembly line. Parts such as a bumper, a radiator, and a cooler condenser mounted on the front of the vehicle body are also provided in the assembly line. Installed at individual stations. Therefore,
The number of work stations in the assembly line has increased,
The length of the line tends to be long and complicated.

On the other hand, for example, JP-A-63-103771 discloses that
Auxiliary equipment such as radiator, head run, bumper, radiator grille, etc. mounted on the front of the vehicle body is assembled into a radiator core support to unitize it, and this nose unit is mounted on the front of the vehicle body to reduce the total length of the body assembly line Techniques are disclosed.

(Problems to be Solved by the Invention) Incidentally, the nose unit includes a shroud door normally separated from the vehicle body side, a plurality of stays extending below the shroud upper, and a cross member connecting lower portions of these stays. , And auxiliary equipment is assembled to the frame, but the front part of the vehicle body to which the nose unit is assembled is required to have required strength and rigidity. Therefore, the strength and rigidity of the front part of the vehicle body are increased by welding the cross member constituting the frame of the nose unit to the front part of the vehicle body. The cross member connecting the lower parts of the plurality of stays constituting the frame will be removed,
For this reason, there is a possibility that the relative positional relationship between the stay and the shroud upper may shift, and in this case, it is difficult to assemble the accessories properly with high accuracy in position.

In addition, when the entire nose unit assembled with the auxiliary components shifted in the manner described above is assembled to the front part of the vehicle body, interference between the misaligned auxiliary components and the member disposed on the vehicle body side may occur. And the like may cause a problem and hinder the assembling work.

In view of the above, according to the present invention, when assembling auxiliary equipment to a shroud frame having a shroud upper separated from the vehicle body side and a stay extending downward from the shroud upper, it is possible to accurately assemble the auxiliary equipment at a regular position. It is an object of the present invention to provide an assembling method capable of accurately assembling the entire shroud frame including accessories and the like to a front portion of a vehicle body.
