摘 要
制造業(yè)是一個(gè)國家或地區(qū)經(jīng)濟(jì)發(fā)展的重要支柱,其發(fā)展水平標(biāo)志著該國家或地區(qū)的經(jīng)濟(jì)實(shí)力、科技水平、生活水準(zhǔn)和國防實(shí)力。而制造業(yè)的生產(chǎn)能力主要取決于制造裝備——機(jī)床的先進(jìn)程度。
本設(shè)計(jì)對(duì)減速器箱蓋連接孔的加工工藝進(jìn)行了詳細(xì)的分析,就其孔的加工提出了“一次裝夾,多工位加工,達(dá)到產(chǎn)品圖樣的精度要求”的思路。根據(jù)這一思路設(shè)計(jì)了鉆孔組合機(jī)床設(shè)計(jì)。
該組合機(jī)床由立柱、立柱底座、中間底座、液壓滑臺(tái)、動(dòng)力箱、多軸箱等組成。本設(shè)計(jì)對(duì)各部分的設(shè)計(jì)進(jìn)行了詳細(xì)的計(jì)算和論證。
關(guān)鍵詞:組合機(jī)床,離合器壓盤,主軸箱,夾具
Abstract
The Manufacture is an important support of economic development in a country or area. Its level of development stands for the economic power, technical and scientific level, living standard and national defensive power of the country or area. While the capability of production in trade of manufacture mostly depends on the advanced producing equipment-machine tool .
This paper has carried out detailed analysis for the case cover processing technology of gear reducer that joins hole, the processing for its hole have put forward the train of thought of " once pack folder, work position is processed , reach the precision requirement of product pattern ".According to this train of thought , have designed the four-axle first work drilling machine of bit alignment.
This paper presents the design and calculating of each part of this machine tool.
