CN202793217U - Testing fixture for left and right connection plate of automobile front-roof beam - Google Patents

Abstract

The utility model discloses a testing fixture for left and right connection plates of an automobile front-roof beam and the testing fixture comprises a testing fixture base. Three reference points are respectively arranged on three corners of the testing fixture base. A testing fixture body is fixedly mounted on the testing fixture base. An outer contour surface of the testing fixture body is matched with a connection plate shape of the automobile front-roof beam. The outer contour surface of the testing fixture body is provided with five positioning blocks. The testing fixture body is provided with two positioning holes matched with positioning pins. The testing fixture body is provided with two test holes. The testing fixture for left and right connection plates provided by the utility model doesn't need a plurality of positioning reference measurement and coordinate transformation. The testing fixture overcomes disadvantages that measurement efficiency is low and production requirements are difficult to be satisfied and test cost is greatly reduced. The testing fixture is especially suitable for mass-produced part test in industry.

Description

Automobile front roof beam left and right connecting plate inspection tool

technical field

The utility model relates to the field of auto parts, in particular to a check tool for the left and right connecting plates of the front roof beam of the automobile.

Background technique

With the development of the economy and the improvement of living standards, the use of cars is increasing year by year. The relationship between vehicles and human beings is really inseparable, and between vehicle manufacturers, vehicle component manufacturers and drivers, not only the performance, safety and fuel-saving effect of the vehicle itself are pursued, but also the components of the vehicle are becoming more and more important. Pay attention.

The production and testing of automobile parts are also becoming more and more advanced, and the precision is getting higher and higher. The left mounting plate has a complex shape and many three-dimensional dimensions, and the required dimensions of various mounting spaces must be within the allowable dimensional tolerance range. Its accuracy directly affects the performance of the vehicle. Now the most commonly used tool for the detection of automobile parts is the three coordinates. This tool takes a long time to detect parts, the measurement efficiency is low, and it is difficult to meet the production requirements.

Utility model content

The purpose of this utility model is to provide the inspection tool for the left and right connecting plates of the front roof beam of the chair and the car, which is very expensive and cumbersome to operate, and the operator uses three coordinates to detect whether the parts are qualified, and does not need multiple positioning benchmarks. And coordinate conversion, overcome the shortcomings of low measurement efficiency and difficult to meet the production requirements, greatly reduce the detection cost, especially suitable for the detection of industrial mass-produced parts.

The technical scheme of the utility model is as follows:

The inspection tool for the left and right connecting plates of the front roof beam of the automobile includes a inspection tool base. Three reference points are respectively set at the three corners of the inspection tool base. The inspection tool body is fixed on the inspection tool base. The outer contour surface of the inspection tool body Matching the shape of the connecting plate of the front roof beam of the automobile, five positioning blocks are arranged on the outer contour surface of the inspection tool body, and two positioning holes are opened on the inspection tool body, and positioning pins are fitted on the positioning holes, and two positioning blocks are opened on the inspection tool body. Detection hole.

The positioning accuracy of the positioning holes is ±0.05mm.

The utility model abandons the previous use of very expensive price, cumbersome operation, and the operator checks whether the parts are qualified through three coordinates, does not need multiple positioning reference measurements and coordinate conversions, overcomes the shortcomings of low measurement efficiency and difficulty in meeting production requirements, and greatly It can greatly reduce the testing cost, especially suitable for the testing of mass-produced parts in industry.
