摘　　要：根据整体成型箱底的实际工艺加工需求,文章设计了一套内外形车切装置,其中内形车切装置可实现不同直径、不同高度产品的加工需求,增强了工装的适应性和工艺性。外形车切装置采用型面吸附压紧方式,既能有效控制加工变形,又极大地提高了作业效率。该成套装置有效解决了无底孔箱底定位夹紧难、加工易变形、专用工装适应性差及加工效率低等问题。Based on the actual processing requirements of the overall forming box bottom,this paper designs a set of internal and external turning devices has been designed.The internal turning device can realize the processing needs of products with different diameters and heights,enhancing the adaptability and manufacturability of the tooling.The external turning device adopts a surface adsorption and compression method,which effectively controls machining deformation and greatly improves operating efficiency.This complete set of equipment effectively solves the problems of difficult positioning and clamping of the bottom of box without bottom holes,easy deformation during processing,poor adaptability of specialized tooling,and low processing efficiency.
