箱蓋機(jī)械加工工藝工裝設(shè)計(jì)

摘要：裝載機(jī)主要用來裝卸成堆散料，也能進(jìn)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(jīng)濟(jì)各個(gè)部門，因此，在國內(nèi)外產(chǎn)量與品種的發(fā)展都較快，是工程機(jī)械中的一個(gè)主要機(jī)種。
    裝載機(jī)根據(jù)不同的使用要求，發(fā)展形成了不同的結(jié)構(gòu)類型。通常，按使用場(chǎng)合的不同，分成露天用裝載機(jī)和井下用裝載機(jī)；接行走系統(tǒng)結(jié)構(gòu)不同，分成輪式裝載機(jī)與履帶式裝載機(jī)；按卸料方式不同，分為前卸式(前端式)、后卸式與回轉(zhuǎn)式裝載機(jī)。
    本文主要是介紹了裝載機(jī)箱蓋加工工藝及加工中所需要的專用夾具的設(shè)計(jì)。首先對(duì)零件進(jìn)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(gè)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(jìn)行基準(zhǔn)面的選擇和對(duì)零件的定位，并遵循一定基本原則，并進(jìn)行定位誤差的分析。加工中還涉及到各種加床夾具的設(shè)計(jì)。本文主要介紹的是專用夾具的設(shè)計(jì)，主要有夾具的定位，零件與零件的連接、夾具體與機(jī)床的連接和吾儕分析。

Cover design of mechanical processing technology and equipment
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.
