摘 要:針对整体式车门型钢铰链在总装难拆卸难安装的现状,基于当下的零件水平和制造水平,本文研究整体式型钢铰链改为分体式型钢铰链的可行性。利用实验获得车门能顺利落位需要的同轴度要求,运用VSA公差分析软件对门的装配过程进行分析研究,将同轴度要求分解到车身侧铰链和车门侧铰链。要求车身侧铰链和车门侧铰链同轴度都不大于0.35mm。从夹具公差、零件公差等方面给出优化方向,确保同轴度可实现。并通过造车验证实验方法正确有效。

Feasibility Study of Split Type Steel Hinge for Car Door Based on Actual Manufacturing Level

Tang Liang

Abstract:Aiming at the status quo that integral steel door hinges are difficult to disassemble and install in the final assembly, based on the current level of parts and manufacturing, this paper studies the feasibility of changing integral steel hinges to split steel hinges. Experiments are used to obtain the coaxiality requirements required for the door to be seated smoothly, and the VSA tolerance analysis software is used to analyze and study the assembly process of the door, and the coaxiality requirements are decomposed into the body side hinge and the door side hinge. It is required that the coaxiality of the body side hinge and the door side hinge is not greater than 0.35mm. Optimizing directions are given in terms of fixture tolerances and parts tolerances to ensure that the coaxiality can be achieved, and is verified through the correct and effective experimental method by building a car.
