Abstract

PURPOSE:To make it possible to assemble automatically necessary functional components by mounting the necessary functional components first on a sub- frame and then mounting partition walls on peripheral parts of an engine frame to form an engine compartment. CONSTITUTION:When a power unit 32 is transferred from above a sub-frame 15, a movable mounting bracket 34 while sliding on a side surface of a guide plate 26 is guided onto a front vehicle width member 16, and a locating pin 35 fits into a locating hole 22 to finish positioning. Under this condition, necessary components to be incorporated and arranged in an engine compartment 13 are mounted. After finishing the mounting of the necessary components, a hood ridge panel 39 integrated with a side member 42 is mounted from overhead. After that, a radiator support panel, etc. are mounted in succession to finish an engine compartment 14.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention provides a car body assembly method in which a car body is divided into a plurality of compartments, necessary parts are assembled for each compartment, and then these parts are joined to complete the car body. Regarding.

2. Description of the Related Art Conventionally, as a method for assembling a vehicle body, a structure shown in FIG. 3 has been proposed (see Japanese Patent Laid-Open No. 61-92965). That is, the vehicle body 1 is composed of an upper body 2 and a lower body 3. The upper body 2 has a structure in which the roof 8 and the front and rear pillars 4 and 51 are integrally molded, while the lower body 3 has a structure in which the roof 8 and the front and rear pillars 4 and 51 are integrally formed. It has a structure in which the engine room 7 is integrally molded. In this configuration, after welding and assembling the upper body 2 and lower body 3 in separate processes, the interior and sacrificial parts of both bodies 2 and 3 are performed in parallel, and in the final process, both bodies 2 and 3 undergo the interior and repair processes. Join bodies 2 and 3. Therefore, in the interior decoration and sacrificial processes, there are no restrictions on items brought into the cabin 6, and automation of work inside the cabin using robots can be promoted.

Problems to be Solved by the Invention However, in the conventional structure, the engine room 7 formed in the lower body 3 has partition walls 7a, 7 on four sides.
It has a structure surrounded by b, 70, and 7d.

For this reason, the power unit including the engine 1 must be lifted into the interior from the bottom of the engine room 7 as before, and this combined with the fact that the work of lifting the engine is heavy and unsuitable for robotization. Assembling the housing parts into the engine room 7 still had to be done exclusively by hand.

The present invention has been made in view of these conventional problems, and provides a vehicle body assembly method that makes it possible to automate the assembly of a heavy power unit and various housing parts.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides necessary functional parts to be housed and arranged in the engine room on a subframe that constitutes the bottom frame member of the engine room of the vehicle body. Then, the side partition members of the engine room and the front and rear partition wall members are assembled to the circumferential portion of the subframe, thereby forming an engine compartment 1 that constitutes the front side of the vehicle body.

Effect In the above structure, when the necessary functional parts are assembled on the subframe, the surrounding area is open, so the necessary functional parts can be assembled from any direction, and the necessary functional parts can be automatically assembled using a robot or the like. By automating the assembly of side bulkhead members and front and rear bulkhead members, which are performed after the necessary functional parts have been assembled, the assembly work of the entire engine compartment made up of these parts can be simplified. Fully automated.
