摘 要
在機(jī)械制造各行業(yè)的工藝過程中廣泛應(yīng)用著各種不同的,用以固定加工對(duì)象,使之占有正確位置,以便接受施工的一種工藝裝備,統(tǒng)稱為夾具。因此,無論是在機(jī)械加工,裝配,檢驗(yàn),還是在焊接,熱處理等冷,熱工藝中,以及運(yùn)輸工作中都大量采用夾具。但在機(jī)械加工中應(yīng)用最為廣泛的是金屬切削機(jī)床上使用的夾具,我們稱其為機(jī)床夾具。它在保證產(chǎn)品優(yōu)質(zhì),高產(chǎn),低成本,充分發(fā)揮現(xiàn)有設(shè)備的潛力,以便工人掌握復(fù)雜或精密零件加工技術(shù),以減輕繁重的體力勞動(dòng)等諸方面起著巨大的作用。因此,機(jī)床夾具的設(shè)計(jì)和使用是促進(jìn)生產(chǎn)迅速發(fā)展的重要工藝措施之一。為此,在本次畢業(yè)設(shè)計(jì)時(shí),選擇了機(jī)床夾具設(shè)計(jì)。
本文主要圍繞機(jī)床鉆孔夾具設(shè)計(jì)為中心。用以鉆發(fā)動(dòng)機(jī)連桿零件,首先通過參觀實(shí)習(xí)讓我們對(duì)夾具設(shè)計(jì)有了初步的了解,特別是對(duì)蓋板式鉆模夾具設(shè)計(jì)的了解更為深刻。然后,在導(dǎo)師的指導(dǎo)下,對(duì)夾具設(shè)計(jì)方案進(jìn)行分析和選擇。選定方案后,。通過查閱相關(guān)夾具設(shè)計(jì)書籍和相關(guān)圖例在鉆孔夾具設(shè)計(jì)過程中,。在查閱了相關(guān)文獻(xiàn)后完成外文翻譯。參考相關(guān)資料完成夾具的總體設(shè)計(jì)。

Abstract
Machinery manufacturing industries in the process of a wide variety of applications for processing a fixed object, so that it occupies the correct position in order to receive a construction technology and equipment, collectively referred to as the fixture. Therefore, whether in the machinery processing, assembly, testing, or in welding, heat treatment, such as cold, heat process, and transport are a lot of work in a fixture. But in machining is the most widely used metal-cutting machine tools for use on the fixture, we called for the machine tool fixture. It guarantees high-quality products, high-yield, low-cost, bring into full play the potential of existing equipment, so that workers have complicated or sophisticated parts processing technologies, to reduce the heavy physical labors, and other aspects play a huge role. Therefore, the fixture of the machine is designed to promote the production and use of the rapid development of one of the important process.
This article mainly revolves the engine bed drill hole jig design is a center. With drills the azimuth training gear shell, first let us through the visit practice have the preliminary understanding to the jig design, was specially more profound to the lap type jig jig design's understanding. Then, under teacher's instruction, carries on the analysis and the choice to the jig design proposal. After designating the plan. Through consult related jig design books and related chart of symbols in drill hole jig design process. After having consulted the related literature completes the foreign language translation. Refers to the correlation data to complete jig's system design.

前 言
在機(jī)械加工過程中,夾具按專業(yè)化程度可分為通用夾具、專用夾具、可調(diào)夾具、組合夾具、成組夾具、標(biāo)準(zhǔn)夾具、隨行夾具、組合機(jī)床夾具等。我這次設(shè)計(jì)的是蓋板式鉆夾具。這是一種專用夾具,專為一工件的一道工序而設(shè)計(jì)的夾具。鉆夾具的主要任務(wù)是保證刀具旋轉(zhuǎn)軸線對(duì)工件定位表面有正確的相互位置,根據(jù)工件的集合形狀和尺寸結(jié)構(gòu)及工藝特性,選擇不同形式的鉆模以保證產(chǎn)品精度和生產(chǎn)率。
在眾多鉆模夾具機(jī)床中,綜合考慮設(shè)計(jì)要求、特點(diǎn)及夾具設(shè)計(jì)原理等的各方面的因素,選擇了用蓋板式鉆模,它一般用于加工小型工件上分布在一個(gè)面上的孔。本文就圍繞此夾具的方案選擇,確定夾具,設(shè)計(jì)夾具等等展開的。
但是,由于知識(shí)的缺陷,設(shè)計(jì)時(shí)考慮的不夠周全,還存在一些錯(cuò)誤,請(qǐng)各位老師和同學(xué)指出,我將做到虛心接受,努力提高自己。
