摘  要
 組合機床，是由大量的通用部件和少量專用部件組成的工序集中的高效率機床。其特點有：結構緊湊、工作質量可靠、設計和制造周期短、投資少、經濟效果好、生產率高等。
 本次設計的題目是銑削組合機床及主軸組件。首先針對所要加工的零件入手，對機床進行總體方案設計，進而確定機床的總體布局，隨后，對主軸組件進行設計。在設計主軸組件時，以主軸為線索，在滿足剛度、精度等要求下，完成其它（如軸承、軸向調節機構、鎖緊機構等）所有零件的設計。
 設計機械加工工藝規程遵循如下原則：
保證零件圖樣上所有技術要求的實現。
必須能滿足生產綱領的要求。
在滿足技術要求和生產綱領要求的前提下，要求工藝成本最低，低耗節能。
盡量減輕工人的勞動強度，保障生產安全。維護環境衛生。
 本產品是按用戶要求而設計的，用戶討論合格后，投入生產，希望指導、鑒定。
 關鍵詞：組合機床，主軸組件，主軸，軸承，軸向調節機構
 

Abstract
 Modular Machine, by the large number of common parts and a small number of specialized components of the process focused efficient machine. Its features include compact, reliable quality, design and manufacturing cycle shorter, less investment and economic effects, and higher productivity.
 The design is the subject of combined milling machine spindle components. First of all, for the processing of parts to start with a general program of machine design, machine tool and then determine the overall layout, then the design of the main components. Components in the design of the spindle to spindle for clues, to meet the stiffness and precision required to complete the other (such as bearings, axial adjustment agencies, locking, etc.) the design of all parts.
 Design mechanical processing order to follow the following principles
 1) To ensure that all parts drawings on the realization of the technical requirements.
 2) Program must be able to meet production requirements.
 3) To meet the technical requirements and requirements of the production program, under the premise of the minimum requirements of cost, low energy.
 4) Minimize the labor intensity of workers, protection of production safety.
 This product is based on user requirements and design, the user discussion after passing the production, hope the guide, identified.
