斜楔式内胀夹头是以圆柱定位,用斜楔夹紧的内夹紧夹头。其特点是结构简单、装夹方便、操作灵活,可在车削、磨削加工中广泛采用。图1是这种内胀夹头的结构图。斜楔1通过钢丝销安装在圆柱的槽内,装上工件后,只要拧紧内六角螺钉,使斜楔2推动心轴移动,就可使斜楔1胀开夹紧工件。加工完成后,松开内六角螺钉,心轴通过弹簧复位,使斜楔1自动松开,这样就轻易地取出工件。使用斜楔式内胀夹头,可以在一次装夹中完成工件外圆和端面,以及钻铰、攻丝等的加工,能较好地
Slant wedge-type expansion chuck is cylindrical positioning, with a wedge clamping chuck clamp. Its features are simple structure, easy clamping, flexible operation, turning, grinding widely used. Figure 1 is the structure of this type of inflation collet. Wedge 1 through the wire pin installed in the cylindrical groove, mounted on the workpiece, as long as the hexagonal screw tighten the wedge 2 to promote the movement of the mandrel, you can make the crook 1 to open and clamp the workpiece. After the machining is completed, loosen the hexagon socket head cap screw, the mandrel is reset by a spring, so that the wedge 1 is automatically released, so that the workpiece can be easily removed. The use of wedge-type expansion of the chuck, the workpiece can be completed in a cylindrical outer cylinder and the end face, as well as drilling hinge, tapping and other processing, better
