车工安全作业技术 | 2012-1-28 8:19:00

1. 车床主轴上装卸卡盘应在停机后进行,不可用电动机的力量取下卡盘。

2. 夹持工件的卡盘、拨盘、鸡心夹的凸出部分最好使用防护罩,以免绞住衣服及身体的其他部位。如无防护罩,操作时应注意距离,不要靠近。

3. 车削外圆面、端面等时,车刀安装在方刀架上,刀尖一般应与车床中心等高。车刀在方刀架上伸出的长度一般应小于2倍刀体高度,垫片要放平整,片数不能太多(不超过3),要用两个螺钉来压紧车刀。这样才能保证切削时刀具稳固,避免折断伤人。

4. 在车床上进行切断工作时,注意切断刀的安装,使刀尖与工件中心等高。如刀尖低于工件中心时,切刀易被压断;如刀尖高于工件中心,切刀后面顶住工件,不易切削。工件的切断处应距卡盘近些,以免切断时工件振动,并避免在顶尖上切断。操作时,要均匀进给,即将切断时,必须放慢进给速度,以保证安全。

5. 用顶尖装夹工件时,顶尖与中心孔应完全一致,不能用破损或歪斜的顶尖,使用前应将顶尖和中心孔擦净。后尾座顶尖要顶牢。
    6.
在车床上钻孔前,必须先车平端面。为防止钻头偏斜折断,可先用车刀划一坑或用中心钻钻中心孔作为引导,钻孔时应加冷却液。孔将钻通时,须放慢进给速度,以防钻头折断。
    7.
车削细长工件时,为保证安全应采用中心架或跟刀架,长出车床部分应有标志。
    8.
削形状不规则的工件时,应装平衡块,并试转平衡后再切削。
    9.
除车床上装有运转中自动测量装置外,均应停车测量工件,并将刀架移动到安全位置。
    10.
用砂布打磨工件表面时,应把刀具移动到安全位置,不要让衣服和手接触工件表面。加工内孔时,不可用手指支持砂布,应用木棍代替,同时速度不宜太快。
