为了保证中型双轮双铧犂,犂头各零件能够自由装配,并能符合技术条件,有两个重要因素。一个是要使犂镜、犂铧、犂侧板都能符合零件图纸技术条件;另一个就是正确地控制犂托曲面及其四孔位置。由于产品图纸上没有直接注明曲面上四孔的位置,只说用标准样板检查,四孔位置不得超过1公厘,而标准样板如何确定就成了问题。我厂自从制作了标准犂头以后,这个现象就消除了,使得犂头装配非常顺利,现在把三个主要措施介绍于后,以供各兄弟厂参考。
In order to ensure that medium-sized two-wheeled double-plow plow, plowshare parts can be freely assembled, and can meet the technical conditions, there are two important factors. One is to make the plowshare, plowshare, plow side panels can meet the technical specifications of parts drawings; the other is to properly control the surface of the plow and its four holes position. As the product drawings do not directly indicate the location of the four holes on the surface, said only with a standard sample inspection, four-hole position can not exceed 1 mm, and how to determine the standard model becomes a problem. Since the factory produced a standard plowshares, this phenomenon has been eliminated, making the plowshare assembly is very smooth, and now the three main measures introduced later, for the reference of the brothers plant.
