ZH1105型柴油機(jī)機(jī)體鉆擴(kuò)組合機(jī)床總體及夾具設(shè)計(jì)
摘要：ZH1105型柴油機(jī)機(jī)體為大批量生產(chǎn)的零件，為了提高生產(chǎn)效率，滿(mǎn)足被加工零件的精度要求且保持加工精度穩(wěn)定，本課題設(shè)計(jì)了一臺(tái)用于ZH1105型柴油機(jī)機(jī)體三面鉆孔的組合機(jī)床。第一部分是總體設(shè)計(jì)，首先，進(jìn)行了總體方案論證，采用單工位三面鉆削組合機(jī)床，刀具選用高速鋼麻花鉆，并根據(jù)切削用量的選擇，計(jì)算切削力、切削扭矩及切削功率，確定主軸直徑、外伸尺寸、接桿型號(hào)，選擇滑臺(tái)、動(dòng)力箱等通用部件，再確定動(dòng)力部件的工作循環(huán)及工作行程，完成機(jī)床聯(lián)系尺寸的制定。最后繪制了三圖一卡。第二部分是夾具設(shè)計(jì)，經(jīng)過(guò)對(duì)被加工零件的全面分析，導(dǎo)向采用固定鉆模板可換鉆套導(dǎo)向，夾緊裝置采用機(jī)械夾緊機(jī)構(gòu)，直接夾壓于工件上，反應(yīng)快捷，夾壓平穩(wěn)可靠，夾具體有良好的剛性，使夾具能長(zhǎng)期保持可靠的精度和穩(wěn)定性。該組合機(jī)床不僅能保證鉆孔精度，還能提高加工效率，降低工人的勞動(dòng)強(qiáng)度。設(shè)計(jì)的夾具定位可靠、夾壓穩(wěn)定、操作方便，達(dá)到了設(shè)計(jì)要求。

The design of the general and jig of the modular machine-tool for drilling the ZH1105 crude oil engine
Abstract：The crude oil engine is made for large quantities of mass production. In order to prone the production efficiency, and meet the precision request of the components processed and the precision stability, it designs a combined machine-tool to be used in the three-cylinder diesel engine with both sides drilling holes. The first part is general design. First, it carries out the argumentation of the overall plan, adopts the combined machine-tool with single location three faces drilling, selects the high-speed steel twist drill. According to the cutting parameters, it calculates the cutting force, the cutting torque and the cutting power, determines spindle diameter, the extend size and the link-pole model, choose sliding table, the power box and so on, then determines the operating cycle and the stroke of the power part, formulates the relation size of the machine-tool. Finally, it draws three figures and one card. The second part is the jig design. Having analyze the work piece, the guiding equipment use the fixed drill plate with replaceable drill bush; the clamp uses the machinery device, it directly presses on the work piece, which responds quickly, fixes steadily and reliably; the jig-body utilizes the frame structure, possess fine rigidity, causes the jig to maintain good long-term precision. This combined machine-tool not only guarantees the drill hole precision, but also enhances the processing efficiency, reduced workers' labor intensity. The jig orients reliably, clamps stably, operates easily, then meet the design request well.
Key words：Modular machine-tool; Drill hole; Jig
