莫斯科“铣刀”工厂根据该厂优秀发明家И.И.契卡列夫的建设,制成钻-铣先六卡爪自动卡模,它可保证所有切削工具都能可靠地固定。自动卡模(见图)由三个部分组成:第一部分——尾部1,附有两个流动轴承2,两个挡环3、4以及可卸突缘5。第二部分——带有螺旋压盖7及保险螺丝8的壳体6。第三部分——压力螺旋,六个卡爪9,六个铰杆,六个螺旋弹簧10和十二个肖钉。尾部通过流动轴承而与壳体组合,两者构成牢固紧密的结合。可卸突缘提供了在铣削时可用必需的拉杆来拉紧锥度的可能。卡爪系统有弹性变形。卡爪在与切削工具联接时形成三条接触线。在相对两卡爪的作用下由于摩擦力产生了很大的
According to the construction of the excellent inventor И.И.CHICHAREL, the Moscow “cutter” factory made a drill-and-mill first six-jaw automatic clamping mold, which guarantees that all cutting tools can be reliably fixed. The automatic die (see picture) consists of three parts: the first part - the tail 1 with two flow bearings 2, two stop rings 3, 4 and a removable flange 5. Part 2 - Housing 6 with screw gland 7 and safety screw 8. The third part - pressure screw, six claws 9, six hinge rods, six coil springs 10 and twelve pegs. The tail is combined with the housing by a flow bearing, both of which form a firm and tight fit. The removable flange provides the possibility of tapering with the necessary tie rods for milling. Claw system elastic deformation. The jaws form three lines of contact when coupled with the cutting tool. Under the action of the two jaws, a large frictional force is generated
