鉆 發(fā)動(dòng)機(jī)支架孔專機(jī)總體及主軸箱設(shè)計(jì)
摘 要：本次設(shè)計(jì)的題目是鉆 17發(fā)動(dòng)機(jī)支架孔專機(jī)總體及主軸箱設(shè)計(jì)，是在發(fā)動(dòng)

機(jī)支架上加工4個(gè)滿足深6mm尺寸要求的 17的孔。
本次設(shè)計(jì)分為總體設(shè)計(jì)和主軸箱設(shè)計(jì)兩個(gè)部分。首先，對(duì)機(jī)床進(jìn)行總體結(jié)構(gòu)的設(shè)

計(jì)，需要確定切削用量，計(jì)算切削力、切削扭矩、切削功率及刀具耐用度，然后

以此確定主軸、外伸尺寸等，繪制“三圖一卡”, 即被加工零件工序圖、加工示

意圖、機(jī)床尺寸聯(lián)系總圖，以及生產(chǎn)率計(jì)算卡。其次，對(duì)主軸箱進(jìn)行設(shè)計(jì)，繪制

設(shè)計(jì)原始依據(jù)圖，確定主軸箱及各個(gè)通用部件的選用，計(jì)算各齒輪的傳動(dòng)比和主

軸的坐標(biāo)位置。最后，根據(jù)分析的結(jié)果，對(duì)齒輪和軸的強(qiáng)度和剛度進(jìn)行校核。
本專用機(jī)床能滿足加工要求，保證加工精度，機(jī)床運(yùn)轉(zhuǎn)平穩(wěn)，工作可靠，結(jié)構(gòu)簡

單，裝卸方便，便于維修、調(diào)整。操作的簡便，減輕了工人的勞動(dòng)強(qiáng)度，提高了

勞動(dòng)生產(chǎn)率。

Overall Design and the Spindle Box Design for Drill Holes on Engine

Support
Abstract: The project topic is the drill hole diameter of 17 engine

bracket and the spindle box design of the whole plane. Processing in

the engine bracket 4 holes to meet the size requirements of deep 6mm

diameter of 17.
The design is divided into two parts overall design and the headstock

design. Firstly, the overall structure of the machine tools design,

need to determine the cutting parameters, calculation of cutting

force, cutting torque, cutting power and tool life, and thus determine

the main shaft, extended size, etc..Rendering the "three plans for a

card", that is, process map parts to be processed, processing diagram,

machine sizes contact General Plan, and the productivity calculation

card. Secondly, the design of the spindle box, drawing the original

design basis, for the identification of various common spindle box and

the selection of components, to calculate the transmission gear ratios

and the principal axis coordinates. Finally, the results of the

analysis, the gear and shaft to check the strength and stiffness.
This special machine can meet the processing requirements to ensure

the machining accuracy, tool smooth operation, reliable, simple, easy

handling, easy maintenance and adjustment. Operation simple, reducing

labor intensity and improve labor productivity.

Key words: special purpose machine; drilling; spindle box;

transmission design
