摘要

組合機(jī)床是以通用部件為基礎(chǔ)，配以按工件特定外形和加工工藝設(shè)計(jì)的專用部件和夾具，組成的半自動(dòng)或自動(dòng)專用機(jī)床。它一般采用多軸、多刀、多工序、多面或多工位同時(shí)加工的方式，生產(chǎn)效率比通用機(jī)床高幾倍至幾十倍。由于通用部件已經(jīng)標(biāo)準(zhǔn)化和系列化，可根據(jù)需要靈活配置，能縮短設(shè)計(jì)和制造周期。因此，組合機(jī)床兼有低成本和高效率的優(yōu)點(diǎn)，在大批、大量生產(chǎn)中得到廣泛應(yīng)用，并可用以組成自動(dòng)生產(chǎn)線。
組合機(jī)床一般用于加工箱體類或非凡外形的零件。加工時(shí)，工件一般不旋轉(zhuǎn)，由刀具的旋轉(zhuǎn)運(yùn)動(dòng)和刀具與工件的相對(duì)進(jìn)給運(yùn)動(dòng)，來實(shí)現(xiàn)鉆孔、擴(kuò)孔、锪孔、鉸孔、鏜孔、銑削平面、切削內(nèi)外螺紋以及加工外圓和端面等。
通用部件按功能可分為動(dòng)力部件、支承部件、輸送部件、控制部件和輔助部件五類。動(dòng)力部件是為組合機(jī)床提供主運(yùn)動(dòng)和進(jìn)給運(yùn)動(dòng)的部件。主要有動(dòng)力箱、切削頭和動(dòng)力滑臺(tái)。
本文介紹了齒輪箱雙端面鏜孔組合機(jī)床設(shè)計(jì),對(duì)它的主要設(shè)計(jì)是組合機(jī)床的總體設(shè)計(jì)、多軸箱設(shè)計(jì)、機(jī)床夾具設(shè)計(jì)及液壓控制系統(tǒng)等設(shè)計(jì)，并進(jìn)行了分析和討論。

DOUBLE END BORING COMBINATION MACHINE TOOL DESIGN FOR GEAR BOX (left)


ABSTRACT

Machine Tool is based on common components, accompanied by the workpiece shape and specific design of special processing of parts and fixtures, consisting of semi-automatic or automatic machine tool. It generally uses multi-axis, multi-tool, multi-process, multi-faceted or multi-station processing means at the same time, productivity is several times higher than the universal machine to a few times. As the common parts have been standardized and series, can be flexibly configured and can shorten the design and manufacturing cycle. Therefore, the combination of both machine tool and efficient low-cost advantages, large, mass production has been widely used, and can be used to form automatic production line.
Combination machine tool generally used for processing of Box or extraordinary form of the parts. Process, the workpiece is generally not rotating, the tool rotation and tool and workpiece relative feed motion, to achieve the drilling, reaming, countersink holes, reaming, boring, milling surface, cutting and processing cylindrical external thread and the other end.
Common functions can be divided into parts according to power parts, bearing parts, transmission parts, control parts and accessories for five. Power is a combination of machine tool components provide the main movement and feed movement of the parts. Main power box, cutting head and the power slide.
This article describes the double-end gearbox combination boring machine tool design, its main design is the combination of machine design, multi-axle box design, tooling and fixture design of hydraulic control system design, and analyzed and discussed.

Keywords Machine Tool; Multi axle box; hydraulic system
