題目:變換齒輪箱體工藝規(guī)程編制及夾具設(shè)計(jì)
摘 要
這次設(shè)計(jì)以變換齒輪箱體為主要加工對(duì)象,主要任務(wù)有兩項(xiàng):第一項(xiàng)是機(jī)體零件加工工藝規(guī)程的編制;第二項(xiàng)
是機(jī)體零件的工裝夾具的設(shè)計(jì)。在對(duì)機(jī)體零件加工工藝的設(shè)計(jì)中,首先對(duì)零件進(jìn)行結(jié)構(gòu)和工藝分析,根據(jù)零件
的材料,生產(chǎn)綱領(lǐng)及其加工要求來(lái)確定毛坯的制造形式,其次進(jìn)行加工基面的選擇與工藝路線的制訂,最后進(jìn)
行加工余量、工序尺寸及切削用量等計(jì)算與確定。在工裝夾具部分的設(shè)計(jì)中,首先是定位基準(zhǔn)的選擇,根據(jù)各
自工序的不同特點(diǎn)來(lái)進(jìn)行定位基準(zhǔn)的選擇,其次進(jìn)行切削力及夾緊力的計(jì)算,最后進(jìn)行誤差分析。
關(guān)鍵詞: 變換齒輪箱 工藝規(guī)程 定位 工裝夾具
Abstract
The graduation design reducer Cover design for the main target, with two major
tasks : Cover is the first part of process design; The second part of Cover the
fixture design. In the Cover Design Process, the first parts of the analysis,
according to parts of the material, Production Program and other rough to
determine the form of manufacturing, followed by processing base with the choice
of route development, Finally for allowance, processes and cutting the size
calculation of the amount of determination. Fixture in the design, the first
base position is the choice According to their respective processes to the
different characteristics of the benchmark location choice, followed by the
cutting force and the conduct of the clamping force, Finally error analysis.
Keywords : Gearhousing Process order Positioning Fixture
