摘  要

組合機(jī)床是一種專(zhuān)用機(jī)床，它是由系列化標(biāo)準(zhǔn)化的通用部件和按被加工零件的形狀及加工工藝要求設(shè)計(jì)的專(zhuān)用部件組成。。組合機(jī)床隨著生產(chǎn)力的發(fā)展，是由萬(wàn)能機(jī)床和專(zhuān)用機(jī)床發(fā)展而來(lái)的。
此次設(shè)計(jì)的目的就是設(shè)計(jì)一臺(tái)組合鉆床，用于加工拖拉機(jī)側(cè)支架的12個(gè)孔。任務(wù)是機(jī)床立式主軸箱的設(shè)計(jì)。這次設(shè)計(jì)的內(nèi)容有組合機(jī)床“三圖一卡”，組合機(jī)床的簡(jiǎn)要設(shè)計(jì)，主軸箱設(shè)計(jì)及其液壓系統(tǒng)設(shè)計(jì)，選擇出機(jī)床總體及各部件的主要參數(shù)，畫(huà)出液壓系統(tǒng)圖。主軸箱的設(shè)計(jì)是這次任務(wù)的重點(diǎn)，它是組合機(jī)床的重要部件之一。它是由通用部件，按照被加工零件的加工要求，根據(jù)專(zhuān)用要求設(shè)計(jì)的。
合理的安排每一根軸的的位置，選擇合適的各級(jí)傳動(dòng)比，將動(dòng)力和運(yùn)動(dòng)由電機(jī)或動(dòng)力部件傳給各工作主軸,使之得到要求的轉(zhuǎn)速和轉(zhuǎn)向從而實(shí)現(xiàn)對(duì)零件的加工。其次，合理安排各主軸和傳動(dòng)軸上齒輪所在的排數(shù)；合理布置進(jìn)油口、放油螺栓、分油盤(pán)及油管的位置；確定主軸和傳動(dòng)軸的支撐方式和預(yù)緊方法也是非常重要的工作。
本文依據(jù)主軸箱的設(shè)計(jì)原則完成了對(duì)結(jié)構(gòu)型式的選擇及動(dòng)力計(jì)算，傳動(dòng)系統(tǒng)的設(shè)計(jì)與計(jì)算，主軸箱總圖設(shè)計(jì),主軸箱坐標(biāo)計(jì)算和液壓部分的設(shè)計(jì)。

DESIGN OF VERTICAL HEADSTOCK USED IN THE DRILLING OF SIDE SUPPORT

ABSTRACT

The modular machine-tool is one kind of special purpose machine. It is composed by the general part and the special-purpose part. The general parts are designed according to the serialized standardization design. The special-purpose part is according to the machined and the processing technological requirement. The modular machine-tool is along with the productive forces development. It comes by the general purpose machine and the special purpose machine development.
The aim of our current design is to design a aggregate drill machine tool , which is used for processing the 12 holes in the stent of tractor. The task is the design of vertical headstock. This design involves the content that including the aggregate machine-tool’s a three charts card"、the designing of vertical headstock  and its hydraulic system、the brief designing of aggregate machine-tool、choosing the overall engine bed and various parts main parameter and drawing the hydraulic scheme. The key point of present design is the vertical headstock designing. Theheadstock is one major components of aggregate machine-tool . It is designed by according to the special-purpose request. It is composed by the general part. It acts according to which is processed the components the processing request. It reasonably arranges each the position of axis. The all levels of velocity ratios is choosing suitably. The power and the movement bequeathed by it to the electrical machinery or the power part each work main axle. It enable each work main axle to obtain the request the rotational speed and changes thus realizes to the components processing. And, reasonably arranging rows between the main shaft and transmission gear; reasonably arranging the position of oil import ,oil-site, vitta, and oil bolt; determining the support way and preload methods between the principal axis and transmission shaft .It’s also my main task.
This article has completed in line with the headstock principle of design to the structure pattern choice and the power computation。Transmission system designing and computation、multi-spindle box assembly drawing designing and partial hydraulic pressure designing hydraulic pressure partial designs.

KEY WORDS：aggregate machine-tool , headstock, driving shaft，vertical，gear
