摘 要
機(jī)械制造業(yè)在國(guó)民經(jīng)濟(jì)中占有重要的地位，是一個(gè)國(guó)家或地區(qū)發(fā)展的重要支柱。其中的工藝學(xué)包括對(duì)一個(gè)零件在加工中的定位、夾緊及工藝路線制定、工序尺寸確定等問題。工序設(shè)計(jì)的合理性往往是提高勞動(dòng)生產(chǎn)率及降低零件報(bào)廢率的主要因素。專用夾具設(shè)計(jì)的簡(jiǎn)單化、高效化和經(jīng)濟(jì)合理化是保證加工質(zhì)量的前提條件。當(dāng)前，制造工藝技術(shù)正向高精度、高效率、低成本、高智能化和潔凈化等方面趨勢(shì)發(fā)展。
本篇論文共包括：銑床升降臺(tái)零件的分析、工藝規(guī)程設(shè)計(jì)及鏜孔夾具的設(shè)計(jì)三大部分。

關(guān)鍵詞：工藝路線,鏜孔夾具


ABSTRACT
The mechanical manufacturing industry holds the important status in the national economy, is a national or the local development important prop. Technology including to a components in processing localization, clamps and the craft route formulation, the working procedure size firmly grades the question. The working procedure design rationality often is enhances the labor productivity and reduces the components condemnation factor the primary factor. The unit clamp designs the simplification, is highly effective and the economical rationalization is guarantees the processing quality the prerequisite. Presently, the manufacture craft technology to the high accuracy, the high efficiency, the low cost, the high intellectualization and is pure and so on the aspect tendency development.
This paper altogether includes: Milling machines with table of variable height with horizontal or vertical spindle-Testing component analysis, technological process design and boring jig design three major parts.

Key word: Craft route, boring jig
