  • 机械零配件加工的原则
  • 本站编辑:杭州宇晨机械有限公司发布日期:2019-10-20 17:03 浏览次数:
相信我们大家都是知道的,我们在做任何事情的时候都是有一定的原则的,就是不知道大家有没有注意观察过。在我们的日常生活中,不知道大家是否了解机械零配件加工的原则呢?
 
I believe that we all know that when we do anything, we have certain principles, that is, we don't know whether we have paid attention to observation. In our daily life, do you know the principle of machining mechanical parts?
 
它的加工原则有以下几点:
 
Its processing principles are as follows:
 
1、先加工基准面。零件在加工过程中,作为定位基准的表面应首先加工出来,以便尽快为后续工序的加工提供精基准。称为“基准先行”。
 
1. First process the datum plane. In the process of machining, the surface used as the positioning reference should be machined first, so as to provide the precision reference for the subsequent processing as soon as possible. It is called "benchmark first".
 
2、划分加工阶段。加工质量要求高的表面,都划分加工阶段,一般可分为粗加工、半精加工和精加工三个阶段。主要是为了保证加工质量;有利于合理使用设备;便于安排热处理工序;以及便于时发现毛坯缺陷等。
 
2. Divide the processing stage. Surfaces with high machining quality requirements are divided into three stages: rough machining, semi finish machining and finish machining. It is mainly to ensure the processing quality, to facilitate the rational use of equipment, to facilitate the arrangement of heat treatment process, and to facilitate the detection of blank defects.
 
3、先面后孔。对于箱体、支架和连杆等零件应先加工平面后加工孔。这样就可以以平面定位加工孔,保证平面和孔的位置精度,而且对平面上的孔的加工带来方便。
 
3. Face before hole. For the box, bracket, connecting rod and other parts, the plane shall be machined before the hole is machined. In this way, the hole can be machined by plane positioning, ensuring the position accuracy of plane and hole, and bringing convenience to the machining of hole on plane.
 
4、光整加工,光整加工后的工件。
 
4. Finish machining, finished workpiece.
