焊接時(shí)，焊工沿軸向運(yùn)條，沿圓周方向順序推進(jìn)，這樣，后一道焊縫都對(duì)前一道焊縫有一定的退火作用。為了使螺紋頭準(zhǔn)確定位，需要加工一定位套，用外力來固定，防止焊接時(shí)的偏斜，該軸螺紋大徑尺寸250圓錐碎石機(jī)的圓錐頭對(duì)壓套的接觸面要求較高，兩工件對(duì)軸中心線的垂直度公差為6～8級(jí)，所以定位套處其配合公差與形位公差的選擇較為重要，經(jīng)實(shí)際測量后，兩圓柱孔的不同軸度要求在0.1mm以內(nèi)，該套加工好后，與螺紋頭、斷軸0280處的間隙在0.20mm左右.(1)將主軸立放，用木板等物搭建了一個(gè)操作平臺(tái)，利于焊工操作，并用定位套將螺紋頭固定好。
潤滑系統(tǒng)是否運(yùn)行正常，是否有漏油現(xiàn)象。皮帶輪齒輪，各部件螺絲等各部件是否牢固，齊全。
