Abstract

The invention discloses a detection process for a car refill opening small door assembly. The process comprises steps: 1) a special detection die is made, and various detection tools are well prepared; 2) the car refill opening small door assembly is fixed on a simulation block (20), and the various detection tools and various detection devices on the detection die are used for carrying out position degree detection, plane degree detection, gap detection and angle detection on a product; and 3) the product with detection completed is placed on a CMM for product data acquisition. After the structure is adopted, no displacement of the product can be ensured from beginning to end, accumulated errors in the case of detection can be reduced, and the detected data are more accurate.

Description

technical field [0001] The invention relates to the technical field of inspection fixtures, in particular to a detection process for an automobile fuel filler door assembly for detecting the outline of a part and the position of each hole. Background technique [0002] The small door assembly of the car fuel filler is a part of the sheet metal of the car. Its production is related to the convenience and practicability of car refueling, and it is also related to whether the matching body sheet metal is consistent. Therefore, the small door of the car fuel filler The assembly is an important component of the car, and its quality and precision in all aspects must have certain requirements. For example, in order to meet the requirement of smooth opening and closing of the fuel filler door without jamming, it is necessary to measure the profile of the fuel filler door. As well as the angle requirements when the fuel filler door is closed and fully opened, it is necessary to meas...
