工农-10拖拉机曲轴用喷镀法修复后,过去在曲轴磨床上磨连杆轴颈,因磨削余量大,磨削时间长,而且轴肩位上不能磨削,需用钳工修整,耗用工时多。我厂在车床上用一曲轴夹具(如图)车削连杆轴颈及轴肩位,经粗车的连杆轴颈,磨削工时由原来的3.5小时降低至1小时,修复成本总计可降低20元。车削时将曲轴装在曲轴固定套6内,然后用垫片螺母锁紧。将固定套6连同曲轴安装在接盘13的定位孔内,并利用校准活动块3校正,使连杆轴颈轴心和接盘轴心同心,然后用压块2、9成三点压紧。固
Worker-peasant tractor crankshaft with the spray method to repair, the past in the crankshaft grinder grinding rod journal, grinding allowance due to grinding time, and the shaft shoulder position can not be grinding, the need to trim fit, consumption Working hours and more. I plant in the lathe with a crankshaft clamp (pictured) turning rod shaft and shoulder bits, the roughing of the connecting rod journals, grinding time from the original 3.5 hours to 1 hour, the total repair costs can be reduced 20 yuan. Crankshaft crankshaft installed in the sleeve 6, and then washer nut lock. The fixing sleeve 6 and the crankshaft are mounted in the positioning holes of the connecting plate 13 and calibrated by the calibrating movable block 3 to make the connecting rod journal center and the connecting shaft center concentric and then pressed with the pressing blocks 2 and 9 at three points. solid
