本卡盘在无法应用真空、磁性及其他装置的场合用于薄片毛坯的夹持。单隙射流卡盘(见图1),包括本体1,其内装有锥块4,形成气室3,用孔2与压缩空气源接通,用本身的锥面与本体定心孔的斜棱组成一环形锥隙5,使空气自气室3排向大气(射流元件)。本体和锥块的端面上分布着流线型定位凸台6。在将毛坯7安装到凸台6上时,气流经环
This chuck is used for the clamping of sheet blanks where vacuum, magnetism and other devices can not be applied. 1), including the body 1, which contains a cone 4, forming a gas chamber 3, with the hole 2 and the compressed air source connected with its own tapered surface and the center of the body centering the bevel edge An annular cone 5 is formed to allow air to be discharged from the gas chamber 3 to the atmosphere (jetting element). Streamlined positioning boss 6 is arranged on the end face of the body and the conical block. When the blank 7 is mounted on the boss 6, the air flows through the ring
