基于分块思想的复杂零件制造技术研究

Study of manufacturing skill for complex parts based on blocking partition

根据零件的几何特征,将难以加工的部分分割成几个简单的组件,为保证各组件的相互位置关系,采用单边分中法确定加工定位基准点、定位面和定位标记,完成加工定位结构的设计。在设计好拼装结构后,即可生成数控程序分别进行加工,并拼装成形。以人耳廓支架的制造为例,验证了复杂零件分块制造的可行性。

According to the geometric characteristics of the parts,its complex parts were divided into several simple portions.To ensure relative position of each subassembly,the method of unilateral centricity was adopted to ensure locating reference point,locating surface and locating sign in the process and accomplish the design of locating structure.As soon as the design of assembly structure was completed,the NC processes were generated and the assembly structure can be scrabbled up immediately.An example of profile bracket of human＇s ear was given to prove the feasibility of manufacture of complex parts.
