【正文】 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 Northeast China39。s Zhangye city during their journey to Kazakhstan, May 5, 2021. 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, 2021. 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 2021. 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。而新的知識(shí)反過來則可以進(jìn)一步促進(jìn)對(duì)已學(xué)知識(shí)有新的理解。在設(shè)計(jì)與校核過程中，電動(dòng)機(jī)的選擇要綜合考慮 轉(zhuǎn)臺(tái) 所輸出力、輸出速度，然后以此倒退求知電機(jī)功率及其外形尺寸。經(jīng)過校核后所有設(shè)計(jì)均符合要求。這樣，不僅影響加工精度，而且加工效率低，勞動(dòng)強(qiáng)度也大。 其蝸桿傳動(dòng)系統(tǒng)裝配圖如圖 313 所示。 此傳動(dòng)軸 左側(cè) 部分與 小錐齒 輪相連接 1n minr? ， 按許用彎扭 應(yīng)力計(jì)算法校核。如圖 36 傳動(dòng)軸的結(jié)構(gòu)示意圖。F FNK? = ? ?2 2121 . 5 3 1 . 5 3 1 . 2 1 7 7 9 6 3 0 . 9 5 9 2 3 . 3 4 1 1 . 9 3 35 0 1 5 5 5tF F a FKF Y Y M P ad d m?????? ? ? ? ? ??? 彎曲強(qiáng)度滿足要求。 圖 32 蝸桿三維示意圖 （ 2）蝸輪 蝸輪齒數(shù) 2Z =31；變位系數(shù) 2X =； 驗(yàn)算傳動(dòng)比 i =31,這時(shí)的傳動(dòng)比誤差為 0，所以成立。 2 6 8 0 .7 4 6 2 0 0H H N HK M P a??? ? ? ?。 蝸桿傳動(dòng)系統(tǒng)的設(shè)計(jì)與校核 選擇蝸桿傳動(dòng)類型 根據(jù) GB/T100851988 的推薦，采用漸開線式蝸桿（ ZI） 。 電機(jī)功率在 傳遞過程中必然有一定的損失。鏈傳動(dòng)與齒輪傳動(dòng)相比，它的制造與安裝精度要求較低，成本也低，但 運(yùn)轉(zhuǎn)時(shí)不能保持恒定的瞬時(shí)傳動(dòng)比；磨損后易發(fā)生跳齒；工作時(shí)有噪聲；不宜用在載荷變化較大、高速和急速反向傳動(dòng)中。從而完成轉(zhuǎn)臺(tái)的傳動(dòng)系統(tǒng)設(shè)計(jì)。 從而 完成 轉(zhuǎn)臺(tái)的傳動(dòng)系統(tǒng)設(shè)計(jì) 。于是，就需要設(shè)計(jì)多主軸鉆床，同時(shí)需要設(shè)計(jì)多工位孔加工的工裝設(shè)備。隨著計(jì) 算機(jī)技術(shù)的不斷發(fā)展，部分 轉(zhuǎn)臺(tái) 正向小型化，便攜化發(fā)展，以滿足人們現(xiàn)場(chǎng)測(cè)量的要求。計(jì)算機(jī)技術(shù)的進(jìn)步己經(jīng)為試驗(yàn)過程的自動(dòng)完成與數(shù)3 據(jù)的自動(dòng)處理提供了條件，研究人員努力將更先進(jìn)、更可靠的技術(shù)應(yīng)用于 轉(zhuǎn)臺(tái) ，保證試驗(yàn)的準(zhǔn)確、高效。中國 轉(zhuǎn)臺(tái) 行業(yè)從上個(gè)世紀(jì) 80 年代以后開始進(jìn)行電子化、微機(jī)化的升級(jí)。 在 C字夾的制作過程中， C字夾螺孔的加工作為主要工藝內(nèi)容，一般均在兩臺(tái)不同的鉆 床上進(jìn)行加工，要裝、卸兩次。 關(guān)鍵詞 加工轉(zhuǎn)臺(tái) ； 蝸輪蝸桿 ； 錐齒輪；滾珠絲桿； ProE ABSTRACT C word clip is carpenter etc monly used tools. C word processing is the screw holes with the main technology content, its processing of a direct impact on the clamping screw in the clamping and loosen the normal movement when. In the C word clip of the production process, the C word clamp screw holes as the main content of the processing technology, in general are two sets of different drilling on the processing, pack, discharge twice. And one can only processing a hole. So, not only affect machining precision and the processing efficiency is low, the intensity of labor is also big. So, need to design more spindle drilling machine, also need to design of progressive hole processing fixtures equipment. And turned in the desktop of progressive drilling, tapping the design of the automatic equipment, progressive must stop type turntable and drilling, tapping fixture design as the main content. This paper summarizes the basic definition and processing turntable for domestic and foreign some important producers results. The second part of the paper is that the thought of three solutions to these solutions and analyzes and pares their advantages and disadvantages. In each other after paring decided to choose the first plan. The third part is that the processing of the main mechanical transmission part turntable for the design and process of checking on them. The main transmission parts processing turntable by the worm, bevel gear, spindle of three parts. After checking all the requirements are designed. Drawing using ProE software table 3 d assembly drawing, then by the whole table 2 d assembly drawing and worm gear and worm, bevel gear and shafts twodimensional drawing. At the end of the article simply introduces the graduation design do some of the ments.
