我厂工人,市级劳模王政永同志在加工液压机的立柱时,在老师傅帮助下,利用3个滚珠轴承滚压工件代替精车获得良好效果。工件表面光洁度要求达到_7,以往是用精车刀以12转/分的转速进行精车,然后用油锉锉光,最后再用细砂布打光。精车一个工件需1.5小时。改进后的情况如附图所示。1是本体,装在跟刀架上。3是滚珠轴承,用滑动架2、心轴4、垫圈6、螺母7固定在本体1上。5是调节螺钉;加工时,调整调节螺钉5,使3个滚珠轴承3跟工件接触,然后以0.15公厘/转的走刀量和600转/分的
I plant workers, municipal workers Wang Zhengyong model workers in the processing of hydraulic column, with the help of the master, the use of three ball bearings rolling parts instead of fine car get good results. Surface finish requirements of the workpiece _7, the past is fine with a sharp knife to 12 rev / min speed fine car, and then filing rasp with oil, and finally light sand cloth. A fine car a workpiece to be 1.5 hours. The improved situation as shown in the figure. 1 is the body, mounted on the knife holder. 3 is a ball bearing, slide 2, spindle 4, washer 6, nut 7 is fixed to the body 1. 5 is the adjustment screw; processing, adjust the adjustment screw 5, so that the three ball bearings 3 contact with the workpiece, and then to 0.15 mm / turn and the amount of 600 rpm
