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)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)。

此次設(shè)計(jì)為連桿鉆孔多軸箱的機(jī)械設(shè)計(jì)。設(shè)計(jì)主要介紹了鉆孔多軸箱的設(shè)計(jì)原理、調(diào)整方法及設(shè)計(jì)計(jì)算過程。通過預(yù)先給定的加工要求可確定所需的計(jì)算參數(shù)，進(jìn)而依據(jù)可調(diào)立式鉆孔多軸箱的設(shè)計(jì)原理來設(shè)計(jì)計(jì)算并校核各個(gè)部位的零件，然后進(jìn)行組裝。本次設(shè)計(jì)可從五大方面進(jìn)行設(shè)計(jì)。通過預(yù)先給定的加工要求計(jì)算并進(jìn)行了雙頭鉆頭的設(shè)計(jì)、傳動(dòng)系統(tǒng)減速箱的設(shè)計(jì)、傳動(dòng)系統(tǒng)電機(jī)的選用、可以保證較高的加工精度和孔間相對(duì)位置精度。

Connecting rod bolt-hole drilling jig and multi-axle pneumatic clamp design

Abstract

In the process machinery manufacturing industries are widely used in a variety of different, to fix the object to be processed so that it occupies a correct position in order to receive a construction of process equipment, collectively referred to as fixtures. Therefore, whether in machining, assembly, inspection, or welding, heat treatment, cold and hot processes, as well as extensive use of transport work in both fixtures. But in machining the most widely used is the fixture for use on metal-cutting machine tools, jigs and fixtures we call it. It is to ensure product quality, high yield, low cost, the full potential of existing equipment in order to grasp the complexity of workers or precision parts processing techniques to reduce the heavy manual labor and other aspects play a huge role. Therefore, the design and use of jigs and fixtures is one of the important technical measures to promote the rapid development of production. For this reason, in this graduation project, select the tool fixture design.

 In this paper, the machine drilling fixture design around the center. For drill rod parts, first by visiting fixture design expertise allows us to have a preliminary understanding, especially understanding the jig fixture design is more profound. Then, under the guidance of instructors, for fixture design analysis and selection. After selecting the program. Through access to relevant books and related fixture design legend in drilling fixture design process. Access to the relevant literature in foreign language translation is completed. References relevant information to complete the overall design fixture.

The design of multi-axle drilling rod mechanical design. Design introduces the drilling of multi-axle box design principles, methods and design adjustment calculation. By processing requirements given in advance to determine the parameters required for the calculation, and then based on adjustable vertical drilling multi-axle box design principles to design calculations and check all parts of the parts, then assembled. This design can be designed from five aspects. By pre-processing requirements of a given calculation and design of the double-headed drill, drive train gearbox design, selection of the motor drive system, ensuring both high precision and accuracy of the relative position of the hole.
