我厂锻造齿坯因没有冲孔设备,齿坯的中心孔,是在车床或钻床上加工。为简化齿坯的装夹,我们设计了自动定心自动夹紧的手动式钻床夹具(如图)。其原理是:利用切削力使工件得到自动定心及夹紧,当切削力越大时,夹紧力也就越大。这种夹具结构简单,制造容易,使用方便,节省了装夹时间,深受欢迎。更换 I plant forging blank because there is no punching equipment, the center of the tooth blank, is in the lathe or drilling machine processing. In order to simplify the clamping of the tooth blanks, we designed a manual drilling fixture with automatic centering and automatic clamping (pictured). The principle is: the use of cutting force to get the workpiece automatically centering and clamping, when the cutting force is larger, the greater the clamping force. This fixture is simple in structure, easy to manufacture, easy to use and saves installation time, and is very popular. replace
