摘　　要：针对固定床加氢反应器冷氢箱支撑主梁焊接后容易产生翘曲或者扭曲变形的问题,基于CAD技术和Pro/E软件协同设计了一套专用焊接夹具。分别设计了专用夹具的夹具底座、底板、定位元件和夹紧元件,然后进行各部件的组合装配。利用计算机仿真技术进行焊接夹具设计,建立焊接产品及其夹具的加工制造模型,以检验设计的可靠性。设计的夹具经试用可以很好地满足实际生产要求。Aiming at the problem that the warping or distortion caused by welding of main girder— part of cold hydrogen tank used in hydrogenation reactor,a special welding fixture is co-designed through the use of three mapping Pro/E software based on CAD technique.The pedestal,base plate,position elements,clamping elements are designed respectively and then assembled together.The computer simulation technology is used to design welding fixture,establish welding products and its fixture manufacturing model,and then verify the feasibility of the welding fixture.The designed fixture can well meet the actual production requirements.
