前言

本次設(shè)計(jì)是為畢業(yè)答辯而準(zhǔn)備的。大學(xué)課程已全部結(jié)束，此次設(shè)計(jì)要把大學(xué)期間學(xué)的東西綜合運(yùn)用，使我們學(xué)的東西融會(huì)貫通，并結(jié)合生產(chǎn)實(shí)習(xí)中學(xué)到的實(shí)踐知識(shí)獨(dú)立地分析和解決工藝問(wèn)題。

本次設(shè)計(jì)傳動(dòng)機(jī)蓋板。內(nèi)容涉及到零件分析、確定毛坯、擬訂工藝、工序設(shè)計(jì)以及兩套夾具設(shè)計(jì)。此次設(shè)計(jì)把我們大學(xué)期間學(xué)的大部分內(nèi)容都用上了，還用到了其它有關(guān)手冊(cè)和圖表。這次設(shè)計(jì)是在學(xué)校的最后一次設(shè)計(jì)，它是一次很好的鍛煉機(jī)會(huì)，為我們未來(lái)從事的工作打下良好的基礎(chǔ)。

由于能力有限，經(jīng)驗(yàn)不足，設(shè)計(jì)中有許多不足之處，希望各位老師多加指教。

摘要

在機(jī)械工業(yè)中，產(chǎn)品由于在質(zhì)量、效能和可靠性等方面有很高的要求，而且構(gòu)造特點(diǎn)一般表現(xiàn)為形狀復(fù)雜、壁薄、剛度低、技術(shù)要求高等。因此，對(duì)它的制造與工藝就顯得非常具有挑戰(zhàn)性和嚴(yán)格性。

本次設(shè)計(jì)是針對(duì)閥導(dǎo)承的制造與工藝, 詳細(xì)地介紹了該產(chǎn)品的整個(gè)加工方案的擬訂過(guò)程，并針對(duì)其中鉆孔的工序所需的專用夾具進(jìn)行了設(shè)計(jì)。工藝設(shè)計(jì)中依據(jù)現(xiàn)有的條件，仍選用傳統(tǒng)的機(jī)械加工方式進(jìn)行編制，但又根據(jù)零件斜孔特點(diǎn)及其結(jié)構(gòu)性能的要求,部分按照非常規(guī)的加工路線進(jìn)行加工，更好的確保了產(chǎn)品的質(zhì)量和技術(shù)性能要求，也體現(xiàn)產(chǎn)品的加工特點(diǎn)。另外，在專用夾具的設(shè)計(jì)中，采用了螺栓聯(lián)接式夾具體，與傳統(tǒng)的焊接式相比，雖然成本略有提高，但更利于夾具以后更換、維修，提高了材料的利用率。此外為次道工序所加工的孔設(shè)計(jì)的夾具還要考慮到加工的孔是斜孔,夾具還要保證其與水平面的夾角,這也增加了夾具設(shè)計(jì)的難度。

Abstract

    In the machinery industry, the products in the quality, performance and reliability requirements are high, and constructed for the general performance characteristics of the shape of complex, thin-walled, low stiffness, high technical requirements. Therefore, the manufacturing and process it becomes very challenging and rigorous nature. 

The design is for the valve guide for the manufacturing and technology, detailed description of the product throughout the course of processing programs, and procedures for which required a special fixture designed. Process design based on existing conditions, still choose the traditional approach to the preparation of machining, but in accordance with the characteristics of parts and the structure of their own performance requirements, some of the processing in accordance with the non-conventional processing routes and better ensure that the products quality and technical performance requirements, but also the characteristics of their products. In addition, the dedicated fixture design, the use of the bolt-type connection specific folder, and compared to traditional welded, although slightly higher cost, but it is more beneficial after the replacement of fixtures, maintenance, improve the utilization of the material. In addition to the processing procedure at the hole of the fixture design must take into account the processing of the hole is the slant-hole, jig also its angle with the horizontal plane, which also increased the difficulty of fixture design.

Key words: Process process dedicated fixture
