在使用要求和充分考虑支撑稳定性的前提下,对长头车车门里板总成的焊装夹具进行总体规划。使用CATIA三维设计软件对通过总体规划的各个点的机械支撑结构进行设计。根据设计结果进行加工、装配和现场的使用实验。通过实际使用情况证明,所设计的焊装夹具机构满足支撑和夹紧要求,能够保证车门里板总成的焊装精度。 In the use of requirements and give full consideration to the stability of the premise of supporting the long-wagon door plate assembly welding fixture for the overall planning. Use CATIA 3D design software to design the mechanical support structure through each point of the master plan. According to the design results of processing, assembly and field use experiment. Through the actual use of proven welding fixture designed to meet the support and clamping requirements, to ensure that the welding assembly precision door assembly.
