【文章內(nèi)容簡介】
造業(yè)被稱為第三利潤源,而控制器具的成本自然也成為較為重要的 一部分,主要有如下兩個方面 ( 1)器具設(shè)計過程中材料的消耗計算更加方便相對二維軟件,在繪制完成整個工程圖,再來計算材料成本,需對所有使用的材料進行單獨計算重量,再進行相加,使用 三維軟件 建模后,可直接輸入材料密度,整體重量就可以計算出來,效率遠高于手動計 算。 ( 2)器具設(shè)計選型更加方便由于現(xiàn)代制造業(yè)零件產(chǎn)品特別汽車零 件新產(chǎn)品均已采用三維軟件來進行設(shè)計,通常情況下,一個產(chǎn)品在設(shè)計完成之后并不會立即大量生產(chǎn),而其中最簡單的零部件同樣也需要選擇合適的標準化包裝,但并沒有足夠多的零件來用以擺放,甚至沒有實物零件,這時我們可以通 過研發(fā)部門獲取零件三維數(shù)模 ,可以準確的獲得這個包裝的重量、 SNP 及包裝所需的標準器具這些數(shù)據(jù),這些都是我們進行物流成本計算所需的重要數(shù)據(jù)。 圖五 同樣對一些更復雜的零件我們可以直接使用數(shù)模來進行專門工位器具的設(shè)計,本文在第四節(jié)會有一個相關(guān)的實際應(yīng)用的例子。通過以上三點,我們不難看出, 使用三維軟件 來設(shè)計工位 器具比二維CAD有很大優(yōu)勢 結(jié)論 經(jīng)過三個月的努力,在 陳國華 老師的悉心指導下,我的畢業(yè)設(shè)計終于告一段落了,這是我大學期間也是我整個學生生涯的最后一份作業(yè),我希望也有信心將它做好。 這次畢業(yè)設(shè)計中我主要完成了發(fā)動機缸蓋從毛坯到成品的機械加工工藝過程,其中包括加工工序的制定,加工方法的選擇,在加工工序中機床、刀具的選擇,加工精度的控制以及機床專用夾具的設(shè)計,同時也完成了缸蓋毛坯圖、零件圖、專用夾具等圖紙的繪制。基本完成了 畢業(yè)課題要求的各項內(nèi)容。 在這最后的三個月的畢業(yè)設(shè)計中我經(jīng)歷了很多, 我學會了如何圍繞著設(shè)計題目我通過各種渠道尋中資料,查找各類工具書,而這些能力無疑是我在以后的工作 與 學習中必須具備的,這次畢業(yè)設(shè)計無疑是將我們在大學中所學到的專業(yè)知識的一個整合,是一個學以致用的過程,讓我在自己的設(shè)計中感到學習的重要性,我會為找出一個參數(shù)、畫標準一個零件而感到高興,也會為當時沒有好好學習,好好聽課而感到深深地懊悔。時間飛逝,轉(zhuǎn)眼四年過去了,我不可能再回到過去,做我當時沒有做好的事情,但是通過這個的畢業(yè)設(shè)計,我會盡量彌補大學期間 我所落下的東西,希望在不久 的將來在自己的工作崗位上能學以致用有所作為,當我回顧我的大學時能不為自己留下遺憾。 參考文獻 [1] 王先奎 .機械加工工藝手冊(第 2 版) ,北京 :機械工業(yè)出版社 ,2022.

The caravan, consisting of more than 100 camels, three horsedrawn carriages and four support vehicles, started the trip from Jingyang county in Shaanxi on Sept 19, 2022. It will pass through Gansu province and Xinjiang Uygur autonomous region, and finally arrive in Almaty, formerly known as AlmaAta, the largest city in Kazakhstan, and Dungan in Zhambyl province. The trip will cover about 15,000 kilometers and take the caravan more than one year to plete. The caravan is expected to return to Jingyang in March 2022. Then they will e back, carrying specialty products from Kazakhstan A small art troupe founded six decades ago has grown into a household name in the Inner Mongolia autonomous region. In the 1950s, Ulan Muqir Art Troupe was created by nine young musicians, who toured remote villages on horses and performed traditional Mongolian music and dances for nomadic families. The 54yearold was born in Tongliao, in eastern Inner Mongolia and joined the troupe in says there are 74 branch troupes across Inner Mongolia and actors give around 100 shows every year to local nomadic people. I can still recall the days when I toured with the troupe in the early 39。80s. We sat on the back of pickup trucks for hours. The sky was blue, and we couldn39。t help but sing the folk songs, Nasun says. The vastness of Inner Mongolia and the lack of entertainment options for people living there, made their lives lonely. The nomadic people were very excited about our visits, Nasun recalls. We didn39。t have a formal stage. The audience just sat on the grass. Usually, the performances became a big party with local people joining in. For him, the rewarding part about touring isn39。t just about sharing art with nomadic families but also about gaining inspiration for the music and dance. Ulan Muqir literally translates as red burgeon, and today39。s performers of the troupe still tour the region39。s villages and entertain nomadic families, but their fame has spread around the world. On May 16 and 17, nearly 100 singers and dancers from the troupe performed at Beijing39。s Poly Theater. Their show, titled Ulan Muqir on the Grassland, depicted the history and development of the art troupe. Being from the region allowed me to embrace the culture of Inner Mongolia and being a member of the troupe showed me where I belonged, Nasun, the art troupe39。s president, who is also a renowned tenor, tells China Daily. During a tour in 1985, he went to a village and met an elderly local man, who told him a story about his friendship with a solider from Shenyang, capital of No
