十字軸機(jī)械加工工藝規(guī)程及工藝裝備設(shè)計(jì)
摘 要
這次設(shè)計(jì)的是十字軸機(jī)械加工工藝規(guī)程及工藝裝備設(shè)計(jì),包括零件圖、毛坯圖、裝配圖各一張,機(jī)械加工工藝過(guò)程卡片和與工序卡片各一張。首先我們要熟悉零件和了解其作用,它位于車床變速機(jī)構(gòu)中,主要起換檔作用。然后,根據(jù)零件的性質(zhì)和零件圖上各端面的粗糙度確定毛坯的尺寸和械加工余量。最后擬定撥差的工藝路線圖,制定該工件的夾緊方案,
畫(huà)出夾具裝配圖。
就我個(gè)人而言,我希望能通過(guò)這次課程設(shè)計(jì),了解并認(rèn)識(shí)一般機(jī)器零件的生產(chǎn)工藝過(guò)程,鞏固和加深已學(xué)過(guò)的技術(shù)基礎(chǔ)課和專業(yè)課的知識(shí),理論聯(lián)系實(shí)際,從中鍛煉自己分析問(wèn)題、解決問(wèn)題的能力,為今后的工作打下一個(gè)良好的基礎(chǔ),并且為后續(xù)課程的學(xué)習(xí)打好基礎(chǔ)。
Abstract
This time I design the lathes of the shift forks CA6140(831005), including that the part pursuing , the blank pursues , assembling pursues , the machine work procedure card the working procedure card every sheet .We should know the part very well and know its effect first , it is worked in the organization which is used for change the speed in a lathe, and the mainly role of the part is alter the speed. Then, we design the dimension of the blank and instrument process a margin of the part according to part character and the harshness of each face .Finally, I design the handicrafts route picture of the shift forks, work out the fastening motion scheme being workpiece's turn , draw up clamp assembling picture.
As far as my individual be concerned, I want to knowing the general productive technology of machine part , consolidating and deepening the knowledge of basic course and specialized course what I have already learned , integrates theory with practice, and improve the
ability to solve problems, what’s more , striking the basis for the future work and the following course’s studying .

序言
機(jī)械制造工藝學(xué)課程設(shè)計(jì)是我們學(xué)完了大學(xué)的全部基礎(chǔ)課、技術(shù)基礎(chǔ)課以及大部分專業(yè)課之后進(jìn)行的.這是我們?cè)谶M(jìn)行畢業(yè)設(shè)計(jì)之前對(duì)所學(xué)各課程的一次深入的綜合性的總復(fù)習(xí),也是一次理論聯(lián)系實(shí)際的訓(xùn)練,因此,它在我們四年的大學(xué)生活中占有重要的地位。
就我個(gè)人而言,我希望能通過(guò)這次課程設(shè)計(jì),了解并認(rèn)識(shí)一般機(jī)器零件的..
