高速線材軋機(jī)滾輪雙端面自動(dòng)加工機(jī)床設(shè)計(jì)（本科畢業(yè)論文設(shè)計(jì)）
摘 要
本設(shè)計(jì)是按系列化標(biāo)準(zhǔn)設(shè)計(jì)的通用部件和工藝加工要求設(shè)計(jì)界的專用零部件組成的專用機(jī)床。隨著電子技術(shù)的發(fā)展，組合機(jī)床正向著數(shù)字化、自動(dòng)化、柔性化、通用化等方向發(fā)展，其結(jié)構(gòu)新穎，配套靈活。
由于工藝性差、對稱性好、加工精度高，本設(shè)計(jì)采用組合機(jī)床，銑床和鏜床的組合，兩面同時(shí)加工。本次論文首先對機(jī)床進(jìn)行方案設(shè)計(jì)，并計(jì)算切削力和切削功率，在次基礎(chǔ)上選擇組合通用部件的型號(hào)，如側(cè)液壓滑臺(tái)、側(cè)底座、動(dòng)力頭、中間滑臺(tái)等，并確定中間底座尺寸，從而得到組合機(jī)床的總體尺寸，并繪制總裝圖。結(jié)合總裝圖得到專用夾具的輪廓尺寸。最后對專用部件，如銑刀等進(jìn)行幾何參數(shù)設(shè)計(jì)，和各種液壓元件的計(jì)算及規(guī)格的選用。
本設(shè)計(jì)分為5個(gè)部分：1 工藝方案設(shè)計(jì)，2銑削刀具及銑削用量的選擇，3 組合機(jī)床總體設(shè)計(jì)，4零部件設(shè)計(jì)，5液壓系統(tǒng)設(shè)計(jì)。

ABSTRACT

In this project, the common parts is based on serrations of the standard design and processing requirements for the design of the component parts for the machine. With the development of electronic technology, the combined machine tool, which has the advantages of novel structure and matching flexible, is in a development of digitalization, automation, flexibility, generalization.
Because of poor manufacturability, better symmetry, and high accuracy, combined machine tool, milling and boring machine combinations is applied, which can process two side synchronously. In this paper, scheme design of machine tool is done first, then cutting force and cutting power are calculated. On that basis, the common parts of the models, such as hydraulic slider side, the side base, the driving force for the first, middle slider, and to identify the middle Base size, composition machine to get the overall size, and the mapping of hand. Hand by combining fixture for the outline of size. Finally, the special components, such as a cutter, and other geometric design parameters, and all kinds of hydraulic components and specifications of the calculation of the selection.
This paper is divided into five parts: 1 Technology programmer design, 2 Milling and choose the amount of milling, 3 combination of machine design, 4 parts and components designed, 5 hydraulic system design.


Key words: combined machine tool, hydraulic slide, the first engine, milling cutter
