摘要： 本設計要求“以質量求發展，以效益求生存”，在保證零件加工質量的前提下，提高了生產率，降低了生產成本，是國內外現代機械加工工藝的主要發展方面方向之一。通過對WH212減速器箱體零件圖的分析及結構形式的了解，從而對減速器進行工藝分析、工藝說明及加工過程的技術要求和精度分析。然后再對減速器箱體的底孔、軸承孔的加工進行夾具設計與精度和誤差分析，該工藝與夾具設計結果能應用于生產要求。
Abstract This Paper requires that" with quality beg development, with benefits seek to live on to store ", under the prerequisite of guaranteeing the quality of element processing , have raised productivity and reduced production cost, is one of mainly direction of domestic and international modern machining technology developing. Through knowing and analysis the configuration of the casing part drawing for WH212 gear reducer, so as to analysis the process, make process explanation and analysis the technical requirement and the precision of gear reducer. Then, carry out the design of clamping apparatus and analysis the precision and error for the processing of bearing hole and the base hole of the casing of gear reducer, this technology and the design result of clamping apparatus can apply in production requirement.
