Problems solved by technology

At present, due to the large production volume, only random inspections are carried out on the vehicle frame longitudinal beam assembly. There are as many as dozens of mounting holes, so it is a waste of time to detect one by one, and random inspection cannot guarantee that all products meet the requirements
In addition, due to measurement errors during the comparison process, the detection data measured by the detection tool needs to be finely trimmed. The detection process is complicated, the cycle is long, the efficiency is low, and the error is large

Abstract

The invention discloses an automobile longitudinal member assembly detecting technique. The technique includes steps of 1, making a dedicated detection mold and preparing different kinds of detection tools; 2, fixing an automobile longitudinal member assembly on different positioning reference blocks and using the different kinds of detection tools and different kinds of detection devices on the detection mold for location degree detection, flatness detection and clearance detection on the product; 3, putting the product passing the detection on a CMM for product data collection. By adopting the structure provided by the invention, the product does not move during the detection process, so that errors accumulated in detection can be reduced and detection data accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of inspection tools, in particular to an inspection process for an automobile frame longitudinal beam assembly for inspecting the surface profile of a part and the position of each hole. Background technique [0002] The frame is the most important load-bearing part in the car, and the frame stringer is one of the key parts, so the stringer plays an important load-bearing role in the car. Longitudinal beams are usually stamped from low-alloy steel plates, and the cross-sectional shape is generally groove-shaped, and some are made into Z-shaped or box-shaped cross-sections. There are many mounting holes on the longitudinal beam assembly of the automobile frame, and it has multiple curved surfaces, so there are mounting holes and mounting surfaces in all directions. Its overall structure is quite complicated, and there are many dimensions with precision requirements, and flatness requirements are also High, s...
