半自動花鍵軸銑(xian)床日常保養規定

一、每班(ban)前設備檢查要(yao)求

1、 將設備(bei)空轉起動(dong)后檢查冷(leng)卻(que)液供應系統是否完好，冷(leng)卻(que)流量(liang)正常，冷(leng)卻(que)噴(pen)淋是否足量(liang)到位，冷(leng)卻(que)液質量(liang)是否符合要求。

2、 檢查設備及裝(zhuang)夾各(ge)部位的(de)調(diao)試；各(ge)配(pei)合部位的(de)間隙調(diao)整及緊(jin)固(gu)；皮帶、安全裝(zhuang)置(zhi)等工(gong)作是否正常。

3、 檢查設(she)備(bei)的(de)電器按鈕(niu)啟動是否(fou)靈活、有效，行程開關、滑塊是否(fou)正(zheng)常工作(zuo)。 二、每班后設(she)備(bei)保養(yang)工作(zuo)要求

1、 將機床各(ge)部位及場地的(de)切屑、垃圾清掃干凈；保證(zheng)各(ge)滑(hua)動面(mian)、絲(si)桿、光桿等處無(wu)油污、“黃(huang)袍”。

2、 按設備潤(run)滑(hua)圖所示(shi)按時加油、換油，檢查(cha)油質是否符(fu)合要求(qiu)；保(bao)證(zheng)油氈、油線清潔(jie)，油窗醒目、油路暢通(tong)；按潤(run)滑(hua)規定的注油孔定期進行(xing)注油。

1. 矩(ju)形花(hua)鍵(jian)軸的(de)(de)加工(gong)(gong)(gong)一般也(ye)是(shi)采用(yong)銑(xian)齒(chi)和滾齒(chi)的(de)(de)加工(gong)(gong)(gong)方式。為提高花(hua)鍵(jian)精度，還可(ke)增加用(yong)花(hua)鍵(jian)磨床來磨削齒(chi)側。精度不高的(de)(de)矩(ju)形鍵(jian)也(ye)可(ke)用(yong)成型銑(xian)刀加工(gong)(gong)(gong)以提高工(gong)(gong)(gong)效，亦可(ke)采用(yong)花(hua)鍵(jian)冷(leng)擠的(de)(de)工(gong)(gong)(gong)藝加工(gong)(gong)(gong)（如一汽底(di)盤廠(chang)剎(cha)車(che)凸輪的(de)(de)加工(gong)(gong)(gong)）。

2. 花(hua)鍵孔的(de)批量(liang)生(sheng)產(chan)一般用臥(wo)式拉床(chuang)（也有的(de)用立式拉床(chuang)，如東風汽(qi)車傳動軸廠）拉制，單件生(sheng)產(chan)亦(yi)可用插(cha)床(chuang)插(cha)制。

3.漸開線花(hua)鍵(jian)軸(zhou)加(jia)(jia)(jia)(jia)工(gong)常(chang)用的(de)加(jia)(jia)(jia)(jia)工(gong)方式是用花(hua)鍵(jian)銑(xian)床和(he)滾齒(chi)機(ji)加(jia)(jia)(jia)(jia)工(gong)，雖(sui)然效率低但(dan)精度(du)高(gao)。為了提gao效率，也(ye)可采取花(hua)鍵(jian)冷(leng)軋(ya)的(de)工(gong)藝方法(fa)（如國內不少合資的(de)汽車減震(zhen)器的(de)生產商），包(bao)裝機(ji)傳(chuan)動軸(zhou)批量(liang)，但(dan)已知(zhi)國內應用的(de)花(hua)鍵(jian)冷(leng)軋(ya)機(ji)都是瑞士(shi)或德國進口(kou)，設備購(gou)置(zhi)昂貴(gui)。也(ye)有采用花(hua)鍵(jian)冷(leng)擠(ji)的(de)加(jia)(jia)(jia)(jia)工(gong)工(gong)藝（如北(bei)京和(he)南京汽車傳(chuan)動軸(zhou)廠），雖(sui)然加(jia)(jia)(jia)(jia)工(gong)效率極高(gao)，可是加(jia)(jia)(jia)(jia)工(gong)精度(du)不如銑(xian)齒(chi)和(he)滾齒(chi)。
