粗鏜連桿大頭孔專用鏜床總體及鏜削頭設(shè)計(jì)摘 要:本課題設(shè)計(jì)一臺(tái)雙面臥式專用鏜床。該組合機(jī)床設(shè)計(jì)的內(nèi)容主要包括總體設(shè)計(jì)和部件設(shè)計(jì)兩部分??傮w設(shè)計(jì):本鏜床用于粗鏜加工連桿大頭孔,一個(gè)工作循環(huán)可同時(shí)粗加工兩個(gè)連桿的四個(gè)孔。根據(jù)工藝和加工的需要,兩兩并排設(shè)計(jì)4個(gè)專用的鏜削頭。為了使主軸軸承結(jié)構(gòu)具有剛度好、精度高及調(diào)整簡(jiǎn)單的特點(diǎn),選擇了1TAb25的鏜削頭。但為了使1TAb25的鏜削頭能夠在本專用鏜床上使用,故將部分結(jié)構(gòu)進(jìn)行了改進(jìn)設(shè)計(jì)。在專用鏜床的設(shè)計(jì)中,完成了專用鏜削頭的總裝配圖和零件圖的設(shè)計(jì)。為保證主軸的剛度與精度,在對(duì)主軸進(jìn)行了校核計(jì)算。主軸中設(shè)計(jì)了兩個(gè)錐度為1:12的的軸段用于安裝支承和固定圓柱滾子軸承,由于鏜削頭的精度要求很高,在軸承處使用了鎖緊螺母進(jìn)行軸向固定。此外,還進(jìn)行了主軸配套軸承的選用和校核。此次設(shè)計(jì)的組合機(jī)床,結(jié)構(gòu)簡(jiǎn)單、維護(hù)方便,盡量使用了通用零部件來降低制造成本,達(dá)到了設(shè)計(jì)的要求。關(guān)鍵字:鏜削頭;組合機(jī)床;連桿;鏜孔Overall and boring design of machine tool for boring connecting barAbstract: This topic is to design a special double-sided horizontal boring lathe. The design of modular machine mainly includes overall design and part design. Overall design: this boring machine that I design is used to process big hole of Linkage, meanwhile, it also can process four hole of two linkage in a work cycle. According to the needs of technology and processing, we should design four special boring head which is two side by two side. Besides, I select 1TAb25 boring head in order to make the structure of spindles bearing having better stiffness, high precision, and simple adjustment as well. But in order to making 1TAb25boring head can be used in this special boring machine, I improved and designed some parts of its structure. During the design of special boring machine, I completed the design of overall assembly and parts assembly, moreover, I check and calculate spindle to guarantee stiffness and accuracy. I design two axis which taper is 1:12 to install bearing and fix bearing of cylindrical roller, I used locking nut to fix the direction of bearing owing to the reason of boring heads high precision. In addition, I select and check matching bearing as well.Modular Machine that I design not only have many advantages such as simple structure, easy maintenance. But also meet the design requirements , also I make full use of General parts to reduce the cost of manufacture in the same time.Key words: Exclusive Boring; Modular Machine; Linkage; Boring hole
