Problems solved by technology

However, since the produced inspection fixture is made of carbon fiber material only, and the prepared inspection fixture is a solid body, the cost is relatively high, and its manufacturing process cannot adopt the integrated molding process, and the assembly process after separate molding will reduce The detection accuracy is improved, and the production cycle is also long

Embodiment Construction

[0019] The specific implementation of the present invention will be described in detail below in conjunction with examples. It should be understood that the examples are provided to illustrate the invention and not to limit the invention. The scope and essential content of the present invention are defined by the claims.

[0020] The preparation method of the vehicle body main inspection tool of the present invention:

[0021] 1. Mold design and processing: According to the shape and size of the product, polymer fiber is selected as the mold material, and then the mold is processed by CNC, which is divided into upper mold 1 and lower mold 2. The upper mold and the lower mold are equipped with a glue injection port and an exhaust glue outlet. The glue injection pipe and the glue injection port are designed to inject glue along the longest side of the grid, and at the same time, the exhaust glue outlet is designed on the opposite side of the glue injection port. .

Abstract

The invention relates to a preparation method of a cubing. The preparation method comprises the following technological steps: design and processing of a mold: the mold is divided into an upper mold and a lower mold which are both provided with a glue injection opening and an exhaust glue outlet; laying: tailored fibre cloth is respectively laid inside a cavity of the upper mold and a cavity of the lower mold so as to obtain two preforms, the two preforms are respectively sealed, vacuum-pumping is carried out, resin is injected through the glue injection opening, and solidification is carried out; and the edge of the solidified mold is coated with an adhesive layer, the mold is closed, and demolding is carried out after the adhesive layer is solidified so as to obtain a hollow fiber gauge product. Integral forming of the cubing can be realized. The preparation method has technical advantages of simplified technology, simple process, short production cycle and the like. In addition, production cost of the cubing is lower, and the cubing is lighter.

Description

technical field [0001] The invention relates to the technical field of processing and manufacturing inspection fixtures, in particular to a method for preparing a main inspection fixture for a vehicle body. Background technique [0002] The body main inspection fixture (cubing), also known as comprehensive inspection fixture or functional master model, is a special inspection fixture for verifying the assembly process manufactured completely according to the design data. This is a very advanced design and quality control concept at present, usually in the model applied during development. The traditional body main inspection tool is made of aviation aluminum and is manufactured in two steps: the first step is to accurately calculate a square size according to the size of the inspection tool components, and then the aviation aluminum raw material is liquefied by high temperature heating Then cool and form the integral aviation aluminum plate of the specified size; the second...
