基于顶盖分拼定位的优化集成设计分析

Based on the Top Points to Optimize the Design of the Integrated Analysis of Spell Positioning

汽车前期研发的样车试制阶段,白车身焊接的焊装线与正式生产线有一定区别。综合考虑人员、成本、场地等因数,采用结构合理的软工装夹具,充分利用现有拼台,优化集成设计顶盖分拼夹具,把分拼夹具集成在总拼拼台上面,并沿用总拼夹具对顶盖进行定位和夹紧。使用三坐标测量仪检测和调整,确保夹具定位精度满足公差范围,可以节约成本,同时提升顶盖分拼的焊接效率和焊接精度。

Car early development of a prototype trialmanufacture phase, white body welding welding line and formal production line has a certain difference. Comprehensive consideration of factor such as personnel, cost, space, using soft jig of reasonable structure, make full use of existing spell, and to optimize the design of the integrated roof spell fixture, spell points fixture integration in total spell spell table above, and continue to use the total spell fixture positioning and clamping on the top. Three coordinates measuring instrument were used to detect and adjust to ensure that the fixture positioning precision meet the tolerance range, fixture assembly,designed by adopting this method can save costs, while increasing the top points of welding efficiency and precision.
