Abstract: This article introduced the principle of welding of fixed equipment and positioning and clamping of stiffening plate. The equipment uses locating pin fixing and pad adjusting as the assembling adjusting way and uses pneumatic control as the automation positioning and clamping way. Based on the structure of the seven types wheat machine cut platform, the equipment use linear guideway as the supporter of left and right wall, bot-tom plate to position different cut platform of different machine type and realize the welding of seven type wheat reap machine cut platform by sharing one equipment. The equipment was proved with properly design and easy to use to fix and assemble with high by actual production. Also the automation positioning and clamping raises the production efficiency and increases production profits.

0前言
在生产过程中，因产品机型多，每种割台体开发一套组焊夹具，将造成夹具开发数量大，投人资金大，占用较大存放场地，给车间生产带来了很多不便。而且以前夹具大多采用手动定位夹紧的方式，生产效率太低。针对上述情况，笔者综合分析了各种割台体的共
