气缸内置，驱动力通过斜楔机构传递。工作稳定可靠。在加工期间，卡盘通过双作用单向阀保持压力。只有在主轴停止时，压缩空气才能通过配气盘和配气圈供给。卡爪具有快移和夹紧行程

Chuck with built-in cylinder, driving force is transmitted through the wedge mechanism. It is stable and reliable in work. Built in double non-return valves maintain the air pressure during machining. The compressed air feed via distributor ring and profile seals only when the spindle stops.With rapid and clamping jaw stroke.

配气盘的两种安装定位方式：

Two ways of mounting the distributor ring:

1、通过固定轴承和防转支架，安装简便，但必须及时调整和润滑固定轴承以保证配气盘处于正确位置。

1.The distributor ring is positioned via fixed bearings and anti-rotation bracket,easy installation but the fixed bearings must be adjusted in time to keep the distributor ring in correct position.

2、使用配气盘支架，卡盘与配气盘不接触。虽然安装调整略微复杂，但维护保养方便经济。

2.Though a bit difficult for chuck mounting and adjusting , it is easy maintenance and lower cost by means of the distributor ring bracket to avoid any contact with the power chuck.
