本钻模(附图)是在摇臂钻床上,用来加工各种筒形零件分布在不同圆周上的多个不同位置和不同直径的径向孔。其采用了卧轴式分度回转结构,导向元件可根据被加工零件孔的位置沿纵向和径向移动,并且可以直接在钻模上读出纵向移动距离的读数。分度回转结构中,主轴7用支承套9安装于钻具体3中,通过它把回转运动传递给工件。回转时,首先转动手柄22,松开主轴的切向夹紧套6,并用星形手柄27拔出分度插销28,然后用把手15转动刻度盘14,通过销子
This drilling die (with photos) is used on a radial drilling machine to process a number of radial holes of different positions and diameters with various cylindrical parts distributed on different circles. It uses a horizontal axis indexing rotary structure, the guide element can be machined parts hole position along the vertical and radial movement, and can be read directly on the drilling longitudinal reading of the distance. Indexing rotary structure, the spindle 7 with a bearing sleeve 9 installed in the drill body 3, through which the rotary motion transmitted to the workpiece. When turning, first turn the handle 22, release the tangential clamping sleeve 6 of the spindle, and pull out the indexing pin 28 with the star handle 27, then rotate the dial 14 with the handle 15,
