壓滾座工藝及鉆M8螺紋底孔夾具設(shè)計(jì)（全套含CAD圖紙）

壓滾座工藝及鉆M8螺紋底孔夾具設(shè)計(jì)（全套含CAD圖紙）,壓滾座,工藝,m8,螺紋,羅紋,底孔,夾具,設(shè)計(jì),全套,cad,圖紙 壓滾座工藝及鉆M8螺紋底孔夾具設(shè)計(jì) 摘要：壓滾座零件加工工藝及鉆床夾具設(shè)計(jì)是包括零件加工的工藝設(shè)計(jì)、工序設(shè)計(jì)以及專用夾具的設(shè)計(jì)三部分。在工藝設(shè)計(jì)中要首先對(duì)零件進(jìn)行分析，了解零件的工藝再設(shè)計(jì)出毛坯的結(jié)構(gòu)，并選擇好零件的加工基準(zhǔn)，設(shè)計(jì)出零件的工藝路線；接著對(duì)零件各個(gè)工步的工序進(jìn)行尺寸計(jì)算，關(guān)鍵是決定出各個(gè)工序的工藝裝備及切削用量；然后進(jìn)行專用夾具的設(shè)計(jì)，選擇設(shè)計(jì)出夾具的各個(gè)組成部件，如定位元件、夾緊元件、引導(dǎo)元件、夾具體與機(jī)床的連接部件以及其它部件；計(jì)算出夾具定位時(shí)產(chǎn)生的定位誤差，分析夾具結(jié)構(gòu)的合理性與不足之處，并在以后設(shè)計(jì)中注意改進(jìn)。 機(jī)床夾具的種類很多，其中，使用范圍最廣的通用夾具，規(guī)格尺寸多已標(biāo)準(zhǔn)化，并且有專業(yè)的工廠進(jìn)行生產(chǎn)。而廣泛用于批量生產(chǎn)，專為某工件加工工序服務(wù)的專用夾具，則需要各制造廠根據(jù)工件加工工藝自行設(shè)計(jì)制造。 關(guān)鍵詞：工藝，工序，切削用量，夾緊，定位，誤差 The pressure roller seat technology and M8 thread bottom hole drilling fixture design Abstract: The pressure roller seat parts processing technology and drilling fixture design is the design of process design, including machining process design and fixture three. In process design should first of all parts for analysis, to understand part of the process to design blank structure, and choose the good parts machining datum, design the process routes of the parts; then the parts of each step in the process to the size calculation, the key is to determine the craft equipment and the cutting dosage of each working procedure design; then the special fixture, the fixture for the various components of the design, such as the connecting part positioning devices, clamping element, a guide element, fixture and machine tools and other components; positioning error calculated by the analysis of fixture, jig structure the rationality and the deficiency, pay attention to improving and will design in. Many types of machine tool fixture, wherein, the use scope broadest generaljig, sizes have been standardized, and has a professional production plant. But widely uses in the volume production, special fixture designed for a workpiece machining process service, need the factory according to the workpiece processing technology to design and manufacture. Keywords: process, cutting dosage, clamping, positioning III 目 錄 目 錄 第一章 緒論 1 1.1 機(jī)械加工工藝概述 1 1.2機(jī)械加工工藝流程 1 1.3夾具概述 2 1.4機(jī)床夾具的功能 3 1.5機(jī)床夾具的發(fā)展趨勢(shì) 3 1.5.1機(jī)床夾具的現(xiàn)狀 3 1.5.2現(xiàn)代機(jī)床夾具的發(fā)展方向 4 第二章 零件的分析 6 2.1零件的作用 6 2.2零件的結(jié)構(gòu)分析 6 2.3零件材料分析 6 2.3.1基準(zhǔn)分析 6 2.3.2零件尺寸分析和粗基準(zhǔn)選擇 6 2.3.3精基準(zhǔn)的選擇 7 3.1 確定毛坯的類型、制造方法和尺寸及其公差 8 3.2 確定毛坯的制造形式 8 3.3基面的選擇 8 3.4制定工藝路線 8 3.5 選擇加工設(shè)備和工藝裝備 11 3.5.1 機(jī)床選用 11 3.5.2 選擇刀具 11 3.5.3 選擇量具 12 第四章 確定機(jī)械加工余量、工序及公差 13 第五章 (鉆M8螺紋底孔)夾具設(shè)計(jì) 33 5.1設(shè)計(jì)要求 33 5.2夾具設(shè)計(jì) 33 5.2.1 定位基準(zhǔn)的選擇 33 5.2.2 切削力及夾緊力的計(jì)算 34 5.3定位誤差的分析 35 5.4 鉆套、襯套、鉆模板設(shè)計(jì)與選用 35 5.5夾具設(shè)計(jì)及操作的簡(jiǎn)要說明 37 總 結(jié) 38 參 考 文 獻(xiàn) 39 致 謝 40 4
