一种车门总成检具铰链连接结构、及其车门总成检测系统和定位检测方法
By designing the hinge connection structure and inspection system for the door assembly fixture, the problem of inconsistency between the part measurement and evaluation and the actual vehicle installation situation in the traditional door assembly fixture and bracket design was solved. This enabled accurate positioning and measurement of the door assembly under the stress state during vehicle installation, improving the reliability of the production process and the optimization effect of part quality.

AI Technical Summary
Traditional door assembly fixtures and bracket designs result in inconsistencies between part measurement and evaluation and actual vehicle installation, affecting part quality optimization and production process implementation. It also makes it difficult to achieve back-to-back force control on the left and right sides of the four-door fixtures and force positioning at the hinges.
A hinge connection structure for a car door assembly inspection fixture was designed, including a hinge force support block and a drive shaft connecting block. The force conversion of the hinge is realized through a movable joint and an extension connecting rod. Combined with the connecting block installed on the fixture and the operating adjustment handle, a car door assembly inspection system is constructed, including a flipping mechanism, an adjustment mechanism and an analysis mechanism, to achieve accurate positioning of the hinge force support and measurement points.
It enables accurate positioning and measurement of the door assembly under load during vehicle installation, ensuring consistency of part measurement results and improving the reliability of the production process and the effect of optimizing part quality.
