2105泵體多軸鉆床設(shè)計(jì)

【摘要】根據(jù)廠里現(xiàn)有自制的2105機(jī)油泵體九孔鉆專機(jī)的工作原理，傳動(dòng)系統(tǒng)機(jī)械結(jié)構(gòu)，在只有少部分維修用測繪零件圖紙外，沒有任何其他的圖紙資料和對(duì)專機(jī)不便拆卸觀看測量箱體內(nèi)部裝配關(guān)系、零件尺寸的情況下，重新設(shè)計(jì)一臺(tái)新的只鉆泵體平面六孔的專機(jī)。本機(jī)床的工作進(jìn)給是通過兩凸輪的轉(zhuǎn)速差來實(shí)現(xiàn)的，快速退回是通過凸輪的急回特性和彈簧作用來實(shí)現(xiàn)的。該裝置的結(jié)構(gòu)簡單，制造周期短，能進(jìn)行各種加工，加工時(shí)傳動(dòng)平穩(wěn)性好、排屑快、效率高，能較好的完成2105泵體上的六孔加工工步。本機(jī)床還通過改變減速箱的結(jié)構(gòu)和箱內(nèi)齒輪配合關(guān)系，從而通過加工其他的平面孔工件也可通過其來完成攻絲工步。                    本課題設(shè)計(jì)的機(jī)床是為加工2105泵體平面上的六孔（2-M6和4-φ9）而設(shè)計(jì)的多軸鉆孔專機(jī)，其的工作原理是：
1.刀具的旋轉(zhuǎn)運(yùn)動(dòng)
刀具的旋轉(zhuǎn)運(yùn)動(dòng)是通過皮帶，花鍵傳動(dòng)和齒輪變速直接驅(qū)動(dòng)鉆頭作旋轉(zhuǎn)運(yùn)動(dòng)，通過變速箱獲得相應(yīng)的切削速度。從而可加工不同孔徑的孔。
2.刀具的進(jìn)給運(yùn)動(dòng)
刀具的進(jìn)給運(yùn)動(dòng)是通過變速箱里的齒輪轉(zhuǎn)動(dòng)，使得與齒輪聯(lián)接的螺旋凸輪轉(zhuǎn)速慢于主軸聯(lián)接的螺旋凸輪。這樣使慢的凸輪推動(dòng)快的凸輪前進(jìn)，使鉆頭完成進(jìn)給運(yùn)動(dòng)，其進(jìn)給速度為兩凸輪轉(zhuǎn)速差的行程。

Pump body 2105 multiracial drilling machine design
           
［abstract］according to existing homemade 2105 machine factory in the pump body nine drill machine working principle, structure, mechanical transmission system of surveying and mapping in only a few maintenance with drawings, without any other drawings and special inconvenience to remove the assembly relation watch measuring the size and the circumstances, to design a new only six hole drilling pump body special plane. This machine to work into two CAM is through the rotation difference, quick return CAM rush through to characteristic and function to realize spring, The device manufacturing cycle is short, simple in structure, and can perform various, processing and transmission stability scraps discharge, high efficiency, fast can better finish on pump body of six 2105 hole processing work. This machine also by changing the structure and reducer gear box, and the relationship with other flat face through processing of work piece can also be accomplished by tapping the work the subject of design for the processing machine 2105 tin pump body plane (2-M6, and 4-φ9) designed for multi-axis drilling jet, and its working principle is:
1. cutting tool rotary motions
The cutting tool rotary motion is through the leather belt, the spline transmission and the gear changing direct drive drill bit makes the rotary motion, obtains the corresponding cutting speed through the gear box.Thus may process the different aperture the hole.
2. cutting tool feed motions
The cutting tool feed motion is through the gear box in gear-driven, causes with the gear coupling spiral cam rotational speed slowly the spiral cam which joins in the main axle.Like this causes the slow cam to impel the quick cam advance, causes the drill bit to complete the feed motion, its feed rate is two cam rotational speed difference traveling schedule.
This engine bed work feed is realizes through two cam rotational speed difference.Returns is fast comes back promptly the characteristic and the spring function through the cam realizes.This equipment structure is simple, the manufacture cycle is short, when can carry on each kind of processing, the processing, the transmission stability is good, the escape of chips is quick; The efficiency is high, can complete on this 2105 pump bodies six to process the labor step well.
