Cushion block for matching of automobile door cover

Abstract

The purpose of the invention is to provide a cushion block for matching of an automobile door cover. The cushion block is simple in manufacturing and exquisite in structure, can simultaneously meet quantifiable adjustment of fining assembling and adjusting, verifying and data collecting of flatness of an engine cover. The cushion block for matching of the automobile door cover is composed of a base and a body. The bottom surface of the body and the top surface of the base are provided with mutually-matched spiral ladders. The body is supported on the base through the spiral ladders. During using, the cushion block is placed on the lower portion of the automobile door cover, the base is fixed, and by adjusting the relative angle of the base and the body, the spiral ladders of the body and the spiral ladders of the base can be overlapped at the different positions, thus the height of the body is adjusted, and the purpose of adjusting the flatness of the automobile door cover by simulating the thread pitch is achieved. The precision of height adjusting relies on precision of the spiral ladders, and the spiral ladders cannot make contact with the automobile door cover, therefore abrasion of the automobile door cover is less, and even if the top surface of the body is subjected to certain abrasion, the precision of adjusting cannot be affected.

Description

technical field [0001] The invention belongs to the technical field of automobile assembly, and in particular relates to a cushion block for matching automobile door covers. Background technique [0002] The assembly and adjustment of the car door cover is a job that requires high skill of the operator. The difficulty of the installation and adjustment work lies in the consistency of the matching state of the assembled body door cover. However, the size of the car door cover will inevitably vary during the manufacturing process. This requires the assemblers to quickly and flexibly handle and absorb the manufacturing tolerances of the door cover through assembly skills, so that the matching state of the assembled door cover on the body has good consistency. The adjustment process of the flatness of the car door cover often needs to rely on the feel of the adjuster to estimate the adjustment amount, which puts forward higher requirements for the skill of the adjuster.

AI Technical Summary

Problems solved by technology

[0003] Welding CP5 (that is, adjustment line) and Cubing matching (that is, comprehensive matching) in the early stage of a new product project often requires repeated fine-tuning and verification of the flatness of the door cover. The flatness adjustment of the bumper block of the car engine cover is used as an example to describe. If using Ordinary polyurethane buffer blocks cannot meet the requirements of refined assembly and verification due to their manufacturing accuracy, wear caused by repeated trial assembly, and collection of assembly data.

Specifically, the current flatness adjustment of the door cover has the following problems: 1. It is necessary for the installer to estimate the adjustment amount based on experience and hand feel, so the collected verification data is not accurate, and it is not easy to analyze and identify problems; 2. During the assembly process of the automobile door cover, if the flatness adjustment block sample is used for trial assembly, the manufacturing tolerance of the sample itself cannot be controlled, and it is necessary to wait and confirm that the door cover flatness adjustment sample is approved before assembly 1. Verify the door cover size and assembly problems, prolonging the trial assembly cycle and assembly efficiency of new car door covers; 3. The door cover flatness adjustment sample is easy to wear during the assembly process. ;4. It is difficult to realize the modularization of the flatness adjustment sample of the door cover, and the size range cannot be accurately divided due to the sample material and manufacturing process errors.
