苏联阿尔美尼亚机械研究所设计和制造了一种新式的弹簧夹头(见附图)。在夹头壳体1中装有切开的弹性衬套2,其中装有弹性夹套3,弹簧4装于两衬套2之间。衬套和弹性夹头靠螺纹盖5保持在壳体中。螺母6与螺纹盖、壳体用差动螺纹连接。壳体上有销子7伸进螺纹盖的槽内,以防螺纹盖转动。 A new collet chuck was designed and manufactured by the Armenian Institute of Machinery (see photo). In the collet housing 1, a cut elastic bushing 2 is fitted, in which an elastic bushing 3 is mounted, and a spring 4 is fitted between the bushing 2. As shown in FIG. The bushing and the collet are retained in the housing by the screw cap 5. Nut 6 with screw cap, housing with differential thread connection. The housing has a pin 7 which extends into the groove of the threaded cover to prevent the threaded cover from rotating.
