摘要：某型轿车前桥由多段曲面薄壁结构焊接而成，由于承力要求其上分布各种加强筋和连接孔等要素，在中等批量制造时必须经过多道工序的周转。结合夹具的设计原理，使用SolidWorks软件自顶向下设计装配体的方法，完成了工序间周转夹具的设计。经过运动仿真、有限元静力学分析、静载试验及动载试验等多个环节检测，夹具能满足生产需求，且具有操作简单、夹紧迅速和安全可靠的特点。该设计方法对于同类薄壁异型件工装夹具的设计具有借鉴意义。

Abstract:The front axle of a certain type of car is welded by multisection curved and thinwalled structure.Due to the requirement of load，various elements such as reinforcement bars and connecting holes are distributed on it，it must be turned around in multiple processes when manufacturing in medium batch.According to the basic principle of fixture design，the method of topdown assembly design with SolidWorks software is used to complete the design of interprocess turnover fixture.Through motion simulation，finite element static analysis，static load test and dynamic load test，the fixture can meet the production requirements，and has the characteristics of simple operation，fast clamping，safety and reliability.This design method can be used for reference in the design of fixture for similar thinwalled with specialshaped parts.
