 摘     要
 液壓缸是一種應用廣泛的執行元件。由于使用條件的多樣性，通常要進行專門設計。本論文所研究的是液壓缸在機械加工過程中的工藝問題和結構設計問題。本文以ZL50轉斗油缸關鍵零件加工和整體結構設計為例，ZL50轉斗油缸是裝載機上的一類油缸，也是其主要性能指標。
 在ZL50油缸的結構設計過程中，有很多未知量，通過查閱參考大量關于液壓缸設計的資料，提取出符合ZL50油缸在機器上的用途和工作要求的有關信息，同時結合一些已有的液壓缸的標準規格和外形尺寸要求設計了一個ZL50轉斗油缸。而在ZL50油缸的加工工藝的設計過程中，要考慮大缸徑油缸的關鍵件零件的材料，技術要求，再選用何種機床對零件進行加工來保證零件尺寸及表面粗糙度，盡量不變形、不破損。主要針對缸筒加工進行分析，本文給出了常用的加工方案，分析后采用合理的加工工藝路線來保證更大程度上滿足零件的加工精度和尺寸要求。
 本文結合了綜合應用所學知識，通過對ZL50轉斗油缸的結構及加工工藝的設計，了解并掌握一個產品從設計到制造的過程。

Abstract
 Hydraulic cylinder is a widely used execute component. Due to the diversified use, hydraulic cylinder is usually designed specially. This topic study is about questions of hydraulic cylinder in machine-finishing process craft and structural design. It takes the machining of key parts and integral structural design of ZL50 cylinder as the example. The ZL50 cylinder is one of hydraulic cylinders of the loader, and also is main performance index of the loader.
 In the structural design process of ZL50 cylinder, there are many unknowns. By consulting extensive information on the design of hydraulic cylinder, to pick up relevant information on the function and job requirement of the ZL50 cylinder. At the moment, combining some existing standard specifications and form factor requirements is to design a ZL50 cylinder. While, in the design process of ZL50 cylinder’s manufacturing, we should take material and technical requirements of key parts of the cylinder into consideration. Then, through selecting machine tool to manufacture accessories, we should guarantee parts’ dimensions and surface roughness, as well as no distortion and no damage. For the analysis of machining of cylinder barrel mainly, this study come up with processing schemes commonly used, and through reasonable analysis of processing technology line to meet precision and size requirements a greater degree.  
 This paper combines the integrated application of the knowledge. Through the structure and processing technology design of ZL50 cylinder, we understand and master a product from design to manufacturing process. In this paper, the integrated application of the knowledge, through the transfer bucket cylinder ZL50 structure and processing technology designed to understand and master a product from design to manufacturing process.
