Description

Description: FIELD OF THE INVENTION The present invention relates to a method for assembling an automobile door.

(Prior Art and Problems Thereof) Generally, a door of an automobile is generally composed of a door body including an inner panel and an outer panel, and a door fitting component such as a window regulator attached to the door body. That is, in the conventional one, the door body is
It is formed by joining the three sides of the inner panel and outer panel, excluding the waistline, so that when mounting the door outfitting parts to the door body, many work holes are provided in the inner panel. It is designed to be used.

More specifically, in the door rigging process (the process of assembling door rigging parts to the door body) found in Japanese Patent Publication No. 60-59101, each door rigging part is inserted through a work hole opened in the inner panel. It was supposed to be attached to each predetermined position on the inner surface of the door body.

For this reason, when the conventional door structure is used, in the work of assembling the door outfitting parts, the door outfitting parts have to be inserted into the work holes of the inner panel and positioned at a predetermined position, so that the movement path of the door outfitting parts is complicated. In addition, since the inner space of the door body is narrow, there is a problem in that workability in assembling the door outfitting parts is poor and automation thereof is difficult.

On the other hand, in addition to the inner panel and the outer panel, a skeleton provided between the inner panel and the outer panel is provided, and the inner panel and the outer panel are assembled to this skeleton to form the door body, and this skeleton is It may be possible to assemble it with door outfitting parts. That is, the door fitting parts are assembled in advance to the skeleton, and the inner panel and the outer panel are assembled to the skeleton to assemble the door. According to this, since the door fitting parts can be assembled without being bothered by the presence of the inner panel or the like, it is possible to improve the assembling property or automate the assembling.

However, in this case, due to the existence of the checker, which is one of the door outfitting parts, a new problem arises in that the inner panel cannot be assembled to the skeleton.

That is, in the past, a checker that regulates the opening of the door in stages has been installed in the door body in a state where it is pulled out from the body, and the checker is attached to the skeleton in the same manner as in the past. In that case, the checker and the inner panel interfere with each other when the inner panel is assembled, which hinders the assembly of the inner panel.

Therefore, in the present invention, when the door body is composed of a skeleton and an inner panel and an outer panel that are attached with the skeleton sandwiched between them, when the checker is attached to the skeleton, the assembling property of the inner panel is not impaired. Another object of the present invention is to provide a method of assembling an automobile door.

(Means and Actions for Solving Problems) In order to achieve the above technical problems, the present invention configures a door body by assembling an inner panel and an outer panel with a skeleton interposed therebetween, and a checker is attached to the skeleton. A method for assembling an automobile door that is assembled, wherein the checker is arranged on the skeleton so that its tip does not protrude beyond the contact surface between the skeleton and the inner panel, and then the checker is attached to the skeleton. The checker is pulled out after the inner panel is assembled.
