Steering column upper and lower cover composite detection fixture

Abstract

The invention belongs to the technical field of automobile spare part detection, and particularly relates to a steering column upper and lower cover composite detection fixture comprising a vertical base, and a steering column upper cover detection fixture and a steering column lower cover detection fixture which are installed at the two vertical surfaces of the base. The steering column upper cover detection fixture comprises a simulation block I, a simulation block II, a simulation block III, a simulation block IV and a simulation block V which are installed on the vertical surface of the base. The steering column lower cover detection fixture comprises a simulation block VI, a simulation block VIII, a simulation block VII, a simulation block IX, a simulation block X, a slide mechanism, a detection pin component and a plug pin component which are installed on the opposite vertical surface of the steering column upper cover detection fixture. According to the steering column upper and lower cover composite detection fixture, one detection fixture can detect two matched steering column upper and lower covers so that the cost can be saved, actual loading can be simulated and the efficiency of tolerance control and debugging can be greatly enhanced.

Description

technical field [0001] The invention belongs to the technical field of auto parts detection, and in particular relates to a composite inspection tool for upper and lower covers of a steering column. Background technique [0002] When manufacturing the plastic interior and exterior parts of automobile body, it is necessary to use inspection tools to check the shape and position deviation of punching, hot pressing and injection molding plastic interior and exterior parts; There are two types of detection, the body detection is the detection of the shape deviation of the plastic interior and exterior parts itself, and the assembly detection is the actual assembly of the plastic interior and exterior parts into a whole on the TAC (Total Assembly Checking Fixture) vehicle inspection tool , to detect the shape and position deviation of the matching state of plastic interior and exterior parts and other parts. [0003] At present, in actual car manufacturing, the shape and positio...

AI Technical Summary

Problems solved by technology

[0003] At present, in actual car manufacturing, the shape and position tolerance control of auto parts mainly depends on the control and adjustment of plastic parts rather than sheet metal parts, so as to achieve the tolerance in line with the original design; the steering column cover is the most visible part of the car interior for the driver. In view of the surface, the shape and position tolerance requirements are strict; in the prior art, the general inspection tool is single-checked to meet the shape and position tolerance of the body, so that there will be unqualified phenomena when the vehicle inspection tool is installed, which will cause damage to the manufacturing process. When producing the steering column cover, generally one mold and two cavities are used to produce the upper and lower covers at the same time, and the inspection tool in the prior art generally needs two inspection tools, each inspection tool only measures one monomer, and lacks a complete set of matching tools.
