Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an assembly inspection tool used for inspecting an assembly condition such as a body panel of an automobile and interior / exterior parts assembled to the body panel, such as assembly accuracy, appearance and sense of continuity. Regarding tools (things that inspect parts in a state equivalent to the actual vehicle).

[0002]

2. Description of the Related Art In an automobile manufacturing process, a plurality of inspection jigs for inspecting parts assembling are mounted on a surface plate of one inspection jig in order to inspect the assembling accuracy of each part to be assembled to a vehicle body (body). It is well known that (hereinafter referred to as models) are assembled, and predetermined parts are attached to these models to inspect the matching, shape, continuity, color matching, and the like (utility model registration No. 2520557). Etc.).

By the way, in the above model, a flange portion corresponding to a terminal fitting portion of inner and outer panels constituting a body panel is provided at a matching portion such as a front windshield and a rear window attached to a vehicle body or a door surrounding portion. There is something to form. The flange portion formed on the model is conventionally formed along the manufacturing process as shown in FIG.

[0004] That is, in producing a mother die which is the basis of the model, as shown in Fig. 4, first, a skeleton is produced by plywood in the step (1), and then a main component and a curing agent are added in the step (2). Epoxy resin (workable resin) is applied to the skeleton. Next, in step (3), after annealing (seasoning) for 5 hours at about 80 ° C., in step (4), a base surface is manufactured with a base resin composed of a main agent, a curing agent, and gypsum. Finally, in step (5), the surface of the annealed epoxy resin is machined into a predetermined shape (generally according to the outer shape of the part).

Next, in transferring and shaping the model,
As shown in FIG. 6, first, in step (1), a mold release agent (Yushiron coat) is applied to the surface of the mother mold to perform mold release treatment,
(2) In the step, the surface of the mother die is gel-coated with a gel-coating resin consisting of a main agent and a curing agent. Next, in the step (3), a square pipe or the like is welded to manufacture a model skeleton, and in the steps (4) and (5), an aluminum plate is placed along the flange forming portion of the mother die and temporarily fixed with screws. Next, in step (6), the skeleton is set on the upper surface of the matrix, and in step (7), an epoxy resin (workable resin) composed of a main agent and a curing agent is placed on the skeleton. Next, in step (8), the aluminum plate is machined to match the inner shape of the part including the flange part, and in step (9) the surface is finished with sandpaper or the like. Next, in step (10), the model provided with the flange portion is released from the mother die by using air, and then in step (11), the model is individually measured using a three-dimensional measuring machine or the like.
Then, after painting the model in step (12), (13)
In the process, the model is assembled on a surface plate through a frame together with other models, and finally the entire model is measured (inspected) in process (14).

[0006]

However, in the above-mentioned conventional model, the aluminum plate (t = 2.0 to 3.0 mm) or the iron plate is used to form the flange portion of the body panel terminal. However, it is difficult to make an aluminum plate or an iron plate along the surface of the mother die within the specified accuracy, and especially a curved surface is difficult. In addition, since the plate thickness is thin, it is difficult to machine both sides, and thus it takes a lot of man-hours and time to manufacture within the specified tolerance.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an assembly inspection jig and a method for manufacturing the same, which can reduce the number of steps and the working time.

[0008]

The assembly inspection jig according to the present invention for achieving the above object produces a plurality of models corresponding to a body panel for assembling interior / exterior parts of an automobile. A method for assembling a plurality of models to inspect a mutual assembled state of the interior / exterior component and the body panel, wherein a flange portion of the body panel where end portions of the interior / exterior component are matched is formed by a liquid epoxy. It is characterized in that it is formed by curing a flexible core material impregnated with a resin, and it can be accurately formed according to prescribed dimensions while maintaining sufficient strength as an inspection jig, and quality can be improved.

Further, the method of manufacturing an assembly inspection jig according to the present invention includes a mold release treatment step of applying a mold release agent to a transfer surface of a mother mold shaped to match the shape of interior and exterior parts of an automobile. A step of coating the mother die with a gel coat resin composed of a main agent and a curing agent, and a step of stretching a flexible core material impregnated with a liquid epoxy resin in a flange forming portion of the mother die,
A step of placing an epoxy resin on the transfer surface of the mother die in a state where a prefabricated skeleton is set, a step of processing along the shape of the internal and external parts after curing the epoxy resin, and the step after the processing step A releasing step of releasing the assembly inspection jig having the skeleton built-in from the mother die, and the core material forming the flange portion is flexible, so that the cutting work is performed easily. It is easy, the number of work steps can be reduced and the work time can be shortened, and even an unskilled person can easily work.
