用自动车床加工多品种、中小批量的产品时,需对每个零件,编制一份工艺规程,设计一份工装,制造一套专用凸轮,其工作量相当繁重,零件成本也相当高;有些工厂就采用普通车床加工这些零件,当然这是落后的方法。为了改善这两种生产工艺,提高经济效益,经过不断摸索,我们推广应用了先进的成组技术,取得了良好的效果。现就有关行业(仪器、仪表、无线电设备等)中,广泛应用的单轴纵切自动车床通用凸轮成组零件的设计,谈谈我们的经验,供大家参考。一、自动车床加工零件的两种分组方法根据我厂零件类别,单轴纵切自动车床所加工零件的分组方法,基本上有下列两种: 1.短小件分组法这种分组法是按零件最大外径相同或相近,外形
When machining multi-varieties and medium and small-batch products with automatic lathes, it is necessary to prepare a process specification for each part, design a tooling set and manufacture a set of special-purpose cams. The workload is quite heavy and the cost of parts is quite high. Some factories On the ordinary lathe machining these parts, of course, this is backward method. In order to improve these two kinds of production processes and improve economic efficiency, we have promoted and applied advanced group technology to achieve good results. Now on the industry (equipment, instruments, radio equipment, etc.), widely used uniaxial Slitting automatic lathe universal cam components of the group to talk about our experience for your reference. First, two automatic lathe processing methods grouped according to our factory parts category, uniaxial Slitting automatic lathe processing parts grouped method, basically the following two: 1. Short piece grouping method This grouping method is based on parts The same or similar maximum outer diameter, shape
