摘 要

本論文主要說明組合機床設計的基本過程及要求。組合機床是按高度集中原則設計的,即在一臺機床上可以同時完成同一種工序或多種不同工序的加工。組合機床發(fā)展于工業(yè)生產末期,與傳統(tǒng)的機床相比:組合機床具有許多優(yōu)點:效率高、精度高、成本低。它由床身、立柱、工作臺、及電源一些基本部件及一些特殊部件,根據不同的工件加工所需而設計的。
在組合機床上可以完成很多工序,但就目前使用的大多數組合機床來說,則主要用于平面加工和孔加工兩大類工序。論文主要內容包括四大部分:
(1)、制定工藝方案 通過了解被加工零件的加工特點、精度和技術要求、定位夾緊情況、生產效率及機床的結構特點等,確定在組合機床上完成的工藝內容及加工方法,并繪制被加工零件工序圖。
(2)、組合機床的總體設計 確定機床各部件之間的相互關系,選擇通用部件和刀具的導向,計算切削用量及機床生產效率、繪制機床的尺寸聯系圖及加工示意圖。
(3)、組合機床部件設計 包括專用多軸箱的設計,傳動布局合理,軸與齒輪之間不發(fā)生干涉,保證傳動的平穩(wěn)性和精確性。專用主軸設計、軸承的選用及電機的選擇等。
(4)、液壓裝置的設計 液壓滑臺、定位夾緊裝置均為液壓控制。并采用了許多液壓控制閥,保證了運動的平衡性,循環(huán)性和精確性。

關鍵詞:組合機床;設計;過程;功能


Abstract
This thesis mainly elucidates the basic process and requirements that design of the combination machine. Combination machine is designed according the fundamental , which highly centralized ,or , more correctly it can process one working procedure or more different working procedures at one time . Combination machine was developed in the end of industrial production compared with traditional machine; combination machine has many advantages , such as high efficiency , high accuracy and low cost . It is composed of some general parts , such as bed ,column ,work able ,power unit ,and some special parts designed according to different work piece machining need.
The preface of a lot of works can be completed on the combination machine, but in regard to the majority current usage of combination machine, then and primarily used for the flat surface to process and the bore to process two big work preface. The main part including :(1) Formulating technological plan We,ve learned the characteristic of the part designed ,accuracy and specification ,locating and fixing ,productivity and machining structure by the practice .Then the technological operation and work order can be determined which can be finished in combination machine.(2) Combination machine frame design determines the interrelation of the different part in the machining tool ,select general parts and tool oriented .Then compute cut feed and productivity finally draw a sketch map of the machine .(3) Combination machine parts design including headstock、proper transmission layout 、shaft and gear move freely without interference which ensure the stability and accuracy during transmission ,then design dedicated select bearings and engine etc.(4) It adopts many hydraulic control valves ,which ensure the stability ,circulation and accuracy .
