摘 要
組合機(jī)床是隨著生產(chǎn)的發(fā)展由萬能機(jī)床和專用機(jī)床發(fā)展來的。組合機(jī)床是按照高度工序集中的原則設(shè)計(jì)的，即一臺(tái)機(jī)床上可以同時(shí)完成許多同一中工序或多種不同工序的加工。組合機(jī)床分大型組合機(jī)床和小型組合機(jī)床兩大類。按配置型式分為單工位和多工位機(jī)床兩大類。
二十一世紀(jì)的制造業(yè)面臨著顧客需求驅(qū)動(dòng)、不可預(yù)測、快速多變和來自全球不斷增加的市場競爭，而且競爭不斷加劇。市場的不斷變化要求制造系統(tǒng)加工的產(chǎn)品品種能夠快速變換以滿足市場需求。
組合機(jī)床是由大量的通用部件和少量的專用部件組成的工序集中的高效率機(jī)床。它具有生產(chǎn)效率高，加工精度穩(wěn)定等特點(diǎn)。
組合機(jī)床在汽車，拖拉機(jī)，柴油機(jī)，電機(jī)，儀器儀表，軍工及縫紉機(jī)、自行車等輕工業(yè)大批量生產(chǎn)中已獲得廣泛的應(yīng)用；一些中小批量生產(chǎn)的企業(yè)，如機(jī)床、機(jī)車、工程機(jī)械等制造業(yè)也已推廣應(yīng)用。組合機(jī)床最適宜于加工各種大中型箱體類零件，如氣缸蓋、氣缸體、變速箱體、電機(jī)座及儀表殼等零件；也可用來完成軸套類、輪盤類、叉架類和蓋板類零件的部分或全部工序的加工。
本設(shè)計(jì)介紹了減振器活塞及支承座上雙面活塞八個(gè)大孔和八個(gè)小孔的多工位立式組合鉆床的設(shè)計(jì)過程。它包括組合鉆床的總體設(shè)計(jì)，主軸箱設(shè)計(jì)和夾具的設(shè)計(jì)三大部分。前者包括組合鉆床總體設(shè)計(jì)，切削用量的制定及刀具的選用。三圖一卡（被加工零件工序圖，加工示意圖，機(jī)床聯(lián)系尺寸圖，機(jī)床生產(chǎn)率計(jì)算卡）編制。中者包括主軸箱結(jié)構(gòu)繪制，主軸箱設(shè)計(jì)原始依據(jù)圖，主軸結(jié)構(gòu)形式的選擇及動(dòng)力計(jì)算。傳動(dòng)系統(tǒng)的設(shè)計(jì)與計(jì)算，主軸箱坐標(biāo)計(jì)算以及主軸箱總圖設(shè)計(jì)，部分軸，齒輪，軸承的校核。后者包括工作臺(tái)的設(shè)計(jì)和夾具的布置，以及完成多工位的機(jī)械傳動(dòng)部分。

Abstract
Combine the tool machine is develop by the all-powerful tool machine and the appropriation tool machine to come along with the development that produce.Combine the tool machine is according to principle design of the high work preface concentration of, namely one pedestal tool machine can complete many same medium work preface or various different work prefaceseseseses to process at the same time up.Combine the tool machine for cent large combination tool machine and the small scaled combination tool machine two major type.Press to install the pattern to is divided into the single work and many tool machine of works two major types.
21 centuries of manufacturing industry faces the customer need to drive, inscrutability, change and come from the market that world continuously increase the competition quickly and much, and compete to turn worse continuously.Market continuously change to request to make the product species that system process can quickly transformation with satisfy the market need.
Combine the tool machine is high-efficiency tool machine of the work preface concentration that be constitute by the in great quantities in general use parts and the appropriation parts of the jot.It has the efficiency of production high, process the accuracy stability etc. characteristics.
Combine the tool machine in the automobile, tractor, diesel engine, electrical engineering, the instrument appearance, the soldier work and sewing machines, bicycle etc. the light industry large quantity quantity produce in have already acquired the extensive application;Some business enterprises that wins the small batch quantity to produce, have already also expanded the application such as the manufacturing industries, such as tool machine, motorcycle and the engineering machine...etc..Combine the tool machine the most suitable and proper in process various body spare parts, if the air cylinder cover, air cylinder body, become soon spare partses such as a body, the electrical engineering and the appearance hull etc.;Also can use to process to part of or all work prefaces of complete stalk set, a dish, the fork and the cover plank spare partses.
This design introduces to reduce to flap the machine piston and pay the design process that a sign type of many works combination of accept the up two-sided piston eight big bores of and eight eyelets drills the bed.It include the combination to drill the bed total design, the principal axis box designs to design the three greatest parts with tongs.The former includes the combination to drill the total design of bed, slicing the establishment and knifes of pare the dosages to have of choose to use.Three one card( was process the spare parts work preface diagram, process the sketch map, the tool machine contact size diagram, the tool machine rate of production calculation card) establishment of figureses.The medium includes a structure of principal axis to draw, a design of principal axis originality according to the diagram, the choice and the motive calculation of the principal axis structure form.Spread the design and calculations of move the systems, the principal axis box sits the mark calculation and a total diagram of principal axis designs, parts of stalk, wheel gear, the pit in the school of the bearings.The latter includes the design and tongses of the work pedestal to arrange, and complete the machine of many works to spread to move the part.
