摘　　要：为实现自动化转型,克服人工缺陷,将磨边轮的1个刀基和29个金刚石合金刀头的高频感应焊接工序实现自动化。为此用数字化设计方法、ANSYS有限元分析和仿真分析方法等技术手段设计了磨边轮焊接专用夹具,从而实现了磨边轮焊接工作的自动化。针对磨边轮的刀基和刀头的结构采用平面和外圆柱面作为基准面的定位方式,夹具采用气压与弹力相结合的复合夹紧方式夹紧,并详细阐述了机构原理,保证定位精度。样机试验证明,能达到设计目的。The high-frequency induction welding process of 1 Diamond foundations and 29 diamond alloy heads of grinding wheels is automated, inorder to achieve automatic transformation and overcome artificial defects. With the help of digital design, ANSYS finite element analysis and simulation analysis, a special fixture for grinding wheel welding is designed, so that the automation of grinding wheel welding is realized. Aiming at the structure of the tool base and cutter head of the grinding wheel, the plane and cylindrical cylindrical surface is used as the datum plane positioning mode. The clamp is clamped by the combined clamping method of air pressure and elastic force, and the mechanism principle is elaborated in detail, so as to ensure the positioning accuracy. The prototype test proves that it can achieve the purpose of design.
