南昌航空大學科技學院學士學位論文 箱蓋機械加工工藝工裝設計 學生姓名：王浩宇 班級：0781052 指導教師：王細洋 摘要：裝載機主要用來裝卸成堆散料，也能進行輕度的鏟掘工作。由于它適用于建筑、礦山、鐵道、公路、水電等國民經濟各個部門，因此，在國內外產量與品種的發(fā)展都較快，是工程機械中的一個主要機種。 裝載機根據(jù)不同的使用要求，發(fā)展形成了不同的結構類型。通常，按使用場合的不同，分成露天用裝載機和井下用裝載機；接行走系統(tǒng)結構不同，分成輪式裝載機與履帶式裝載機；按卸料方式不同，分為前卸式(前端式)、后卸式與回轉式裝載機。 本文主要是介紹了裝載機箱蓋加工工藝及加工中所需要的專用夾具的設計。首先對零件進行了工藝性分析了解各加工面所需要打到的加工精度，確定各個加工面的加工余量。制定合理的能夠滿足加工需要的工藝方案。為了保證零件的加工精度需要進行基準面的選擇和對零件的定位，并遵循一定基本原則，并進行定位誤差的分析。加工中還涉及到各種加床夾具的設計。本文主要介紹的是專用夾具的設計，主要有夾具的定位，零件與零件的連接、夾具體與機床的連接和吾儕分析。 關鍵詞：設計流程 設計規(guī)則 機械設計 指導教師簽名： Cover design of mechanical processing technology and equipment Student name: Wang Haoyu Class: 0781052 Supervisor: Wang Xiyang Abstract: Loader piles mainly used for loading and unloading of bulk materials, but also for mild shovel work. As it applies to construction, mining, railway, highway, water and other economic departments, therefore, the development of domestic production and the varieties are faster, is a major construction machinery models. Loader according to different requirements, develop and form a different structure types. Usually, by the use of different occasions, into the open hole with a loader and Loader; then walking system of different structures, into wheel loaders and crawler loaders; by discharge in different ways, into the former dump (front-end ), after the dump and rotary loaders. This article is to introduce a loader cover processing technology and processing needs special fixture design. First of all parts of the process of analysis needed to understand the processing of surface machining accuracy to hit, to determine the allowance of each machined surface. To develop a reasonable process to meet the processing needs of the program. To ensure the machining accuracy is required datum selection and positioning of parts, and follow certain basic principles, and the positioning error analysis. Processing also involves a variety of extra fixture design. This paper describes the design of special fixture boring, there are fixture positioning, parts and components of the connection, the connection with the machine specific folder and Wuchai analysis.
