無心磨的概述及加工

無(wu)心磨(mo)(mo)(mo)床,是無(wu)需采(cai)用(yong)工(gong)(gong)(gong)件(jian)(jian)(jian)的樞軸(zhou)準(zhun)確定(ding)(ding)位(wei)而進(jin)行磨(mo)(mo)(mo)削的一(yi)類數控(kong)磨(mo)(mo)(mo)床,重(zhong)要(yao)由磨(mo)(mo)(mo)削沙(sha)輪(lun)(lun)片(pian)、調整輪(lun)(lun)和工(gong)(gong)(gong)件(jian)(jian)(jian)固(gu)定(ding)(ding)支(zhi)(zhi)架三個(ge)機構(gou)構(gou)成,在這其中(zhong)磨(mo)(mo)(mo)削沙(sha)輪(lun)(lun)片(pian)實(shi)際擔任磨(mo)(mo)(mo)削的工(gong)(gong)(gong)作(zuo)上,調整輪(lun)(lun)控(kong)制工(gong)(gong)(gong)件(jian)(jian)(jian)的旋轉,并控(kong)制工(gong)(gong)(gong)件(jian)(jian)(jian)的進(jin)刀速度(du),針對(dui)工(gong)(gong)(gong)件(jian)(jian)(jian)固(gu)定(ding)(ding)支(zhi)(zhi)架乃在磨(mo)(mo)(mo)削時(shi)支(zhi)(zhi)點工(gong)(gong)(gong)件(jian)(jian)(jian),這三種零(ling)件(jian)(jian)(jian)可(ke)有多(duo)種多(duo)樣互相配合的方法,但(dan)停止研磨(mo)(mo)(mo)之(zhi)外,基本概(gai)念上邊(bian)一(yi)樣。

無(wu)(wu)心(xin)磨(mo)(mo)(mo)床(chuang)重要有(you)(you)三種磨(mo)(mo)(mo)削(xue)方法(fa);依據式(shi)、切入(ru)(ru)式(shi)和(he)切入(ru)(ru)一依據式(shi)、依據式(shi)不(bu)經(jing)意(yi)磨(mo)(mo)(mo)削(xue)。工(gong)(gong)(gong)件(jian)(jian)(jian)(jian)沿沙輪(lun)片(pian)軸(zhou)(zhou)線方向進(jin)(jin)刀進(jin)(jin)行磨(mo)(mo)(mo)削(xue)。調(diao)整導輪(lun)軸(zhou)(zhou)線的(de)(de)微(wei)小傾角來進(jin)(jin)行工(gong)(gong)(gong)件(jian)(jian)(jian)(jian)軸(zhou)(zhou)頸(jing)走刀。合(he)適(shi)磨(mo)(mo)(mo)削(xue)長細圓柱(zhu)狀工(gong)(gong)(gong)件(jian)(jian)(jian)(jian)。無(wu)(wu)管理處(chu)孔的(de)(de)短(duan)軸(zhou)(zhou)和(he)軸(zhou)(zhou)類零件(jian)(jian)(jian)(jian)生(sheng)產加(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)件(jian)(jian)(jian)(jian)等。切入(ru)(ru)式(shi)不(bu)經(jing)意(yi)磨(mo)(mo)(mo)削(xue)。墊(dian)塊上(shang)(shang)邊(bian)有(you)(you)軸(zhou)(zhou)頸(jing)支點(dian),工(gong)(gong)(gong)件(jian)(jian)(jian)(jian)支撐(cheng)點(dian)在(zai)(zai)墊(dian)塊一定位置(zhi)上(shang)(shang),以沙輪(lun)片(pian)或導輪(lun)切入(ru)(ru)進(jin)(jin)行磨(mo)(mo)(mo)削(xue)。用(yong)(yong)于磨(mo)(mo)(mo)削(xue)帶(dai)軸(zhou)(zhou)環(huan)或模座的(de)(de)工(gong)(gong)(gong)件(jian)(jian)(jian)(jian)以及圓錐(zhui)體(ti),球體(ti)或其他(ta)旋(xuan)轉(zhuan)體(ti)工(gong)(gong)(gong)件(jian)(jian)(jian)(jian)。切入(ru)(ru)一依據式(shi)不(bu)經(jing)意(yi)磨(mo)(mo)(mo)削(xue)是這二者的(de)(de)復(fu)合(he)性(xing)。此外,也是有(you)(you)斷開走刀片(pian)式(shi)磨(mo)(mo)(mo)削(xue)和(he)使帶(dai)臺(tai)階的(de)(de)工(gong)(gong)(gong)件(jian)(jian)(jian)(jian)在(zai)(zai)軸(zhou)(zhou)頸(jing)進(jin)(jin)、退(tui)的(de)(de)內螺紋走刀片(pian)式(shi)磨(mo)(mo)(mo)削(xue)。無(wu)(wu)心(xin)磨(mo)(mo)(mo)床(chuang)生(sheng)產率較高。多用(yong)(yong)于許多生(sheng)產加(jia)工(gong)(gong)(gong),以便(bian)進(jin)(jin)行自動化控制。

無心(xin)磨床的特性無心(xin)磨床機構特性與一般數控磨床相比(bi)較有以下特性。

1、不斷生(sheng)產制造(zao),無需下刀,夾裝工件等復制時間較短,生(sheng)產制造(zao)高(gao)效(xiao)率。

2、支撐架和導輪機構比一般數控磨床(chuang)、中心(xin)架機構支撐點(dian)彎曲剛度好,鉆削(xue)量可(ke)以(yi)非(fei)常大,并有利于長細軸(zhou)類零件(jian)工(gong)件(jian)的生產制造,以(yi)便進行髙速磨削(xue)和超超強力(li)磨削(xue)。

3、無(wu)心磨床工件(jian)靠(kao)內(nei)螺紋(wen)在機(ji)構上(shang)(shang)準(zhun)確定位,磨削量是工件(jian)直(zhi)徑(jing)上(shang)(shang)的(de)容積,故沙輪片的(de)磨爛、進(jin)刀機(ji)構的(de)賠(pei)付(fu)和切入機(ji)構的(de)不斷精度級別誤差對零件(jian)直(zhi)徑(jing)規格型(xing)號精度的(de)傷害(hai)。僅有一般數控(kong)磨床的(de)一半(ban),不需打(da)管(guan)理處孔(kong),且(qie)以便進(jin)行上(shang)(shang)、切料自動化控(kong)制。

4、寬沙輪(lun)(lun)片無(wu)心(xin)磨(mo)床依據式(shi)機(ji)構、可采用(yong)提升(sheng)每(mei)一(yi)次的生(sheng)產加工的剩(sheng)下(xia)量,在切入磨(mo)時可對多(duo)元性面依次形磨(mo)削或多(duo)沙輪(lun)(lun)片磨(mo)削,生(sheng)產制造高效率,主要用(yong)途廣(guang)。

5、無心磨(mo)床(chuang)確(que)保磨(mo)削(xue)表面和(he)非磨(mo)削(xue)表面的(de)(de)相對位置(zhi)精(jing)度(du)(平面度(du),平面度(du)等)的(de)(de)機構,磨(mo)削(xue)徑向時有時無的(de)(de)外表面時同軸度(du)較(jiao)差。

6、磨削(xue)表面易導致奇數次(ci)棱同軸(zhou)度(du),如(ru)非(fei)常大(da)時一般(ban)會造成準確測量規格型號小于很大(da)實體規格型號的出現幻覺,而傷害安裝質量和工作(zuo)上特性。

7、加工(gong)中心(xin)調(diao)整較(jiao)復雜、耗時間(jian),每拆卸(xie)不(bu)一樣直徑的(de)工(gong)件需沖(chong)調(diao)整支撐架高度,與間(jian)隔及有(you)關的(de)制作工(gong)藝(yi)基(ji)本參數。故調(diao)整技(ji)術實力非常大,不(bu)宜小批及單件生產(chan)加工(gong)。
