摘 要
機(jī)械生產(chǎn)是研究產(chǎn)品設(shè)計(jì)、生產(chǎn)、加工制造、銷售使用、維修服務(wù)和回收再生的整個(gè)過程的工程學(xué)科。現(xiàn)代機(jī)械生產(chǎn)技術(shù)越來越發(fā)達(dá),但在新型的生產(chǎn)動(dòng)力普遍使用之前,原有的成熟生產(chǎn)條件依然被使用,在機(jī)械生產(chǎn)過程中發(fā)揮著重要的作用。
2105柴油機(jī)是機(jī)械生產(chǎn)中廣泛應(yīng)用的生產(chǎn)設(shè)備,轉(zhuǎn)速器盤做為其中連接手動(dòng)裝置和油門,實(shí)現(xiàn)無級變速的重要零件,是不可替代的部件。對其進(jìn)行分析計(jì)算,并根據(jù)結(jié)果選用相應(yīng)的加工機(jī)床,設(shè)計(jì)相應(yīng)的夾具,是本次畢業(yè)設(shè)計(jì)的主要內(nèi)容。
設(shè)計(jì)從轉(zhuǎn)速器盤的整體分析開始,經(jīng)過毛壞選料、工藝分析、確定加工規(guī)程,再逐一對要加工的表面進(jìn)行詳細(xì)的計(jì)算,并查找工具書籍進(jìn)行機(jī)床刀具等的選用。最后選取零件上的Φ10mm的孔進(jìn)行了加工夾具的設(shè)計(jì)。

The Plate Processing Technology and Its Speed Fixture Design
Student: BIN Shang-wen Teacher: DAI xuan-jun
Abstract: Mechanical production is the study of product design, production, manufacture, sale, repair and regeneration of the whole process of engineering disciplines will be added. Modern machinery manufacturing technology more and more developed, but in power prior to the large-scale use of new production, original mature production conditions are still being used, in machinery production plays an important role in the process. 2105 mechanical equipment used in the production of diesel engines, speed disk for which connection manual installation and the gas, important part to realize continuously variable, is irreplaceable part. Analysis and calculation of its, and selected according to the results of the processing machine tools, design the appropriate fixture, is the main content of this graduation. Designed starting from the overall analysis of the speed, after bad materials, process analysis, determine the processing rules and detailed calculations of the surface to be processed one by one, and find the tools selection of books, such as machine tools. Φ10mm on the last selected part design of fixture for hole machining.
Key words: mechanical transmission tachometer disk fixture design
