本文介绍的车床上用特种刀架,由刀座(图1)及刀夹(图2)两部分组成,制造及使用均很方便,且具有良好的刚性。图1中体座9的中间孔与车床小刀架1上的心轴6相配合,在体座的燕尾槽中根据加工需要可选用图2中任一个刀夹(现采用图2a 的刀夹)。在方头轴8上通过长键7同时固定着两个偏心轮10,使用时转动轴8,由于偏心轮的作用,分别推动两个套筒11,使两个压块12同时夹紧或松开两个刀夹(松开是借助子弹簧的弹力),以便旋动螺钉16进行对刀或更换刀夹。由 This article describes the use of special turret lathe, the seat (Figure 1) and the tool holder (Figure 2) of two parts, manufacture and use are very convenient, and has good rigidity. In Figure 1, the center hole of the base 9 cooperates with the mandrel 6 on the turret small turret 1, and any one of the tool holders shown in Fig. 2 can be selected according to the processing requirements in the dovetail groove of the base (now the tool holder shown in Fig. 2a) . In the square head shaft 8 by the long key 7 at the same time fixed two eccentric 10, the use of the rotating shaft 8, due to the role of the eccentric wheel, respectively, two sleeves 11 are pushed so that the two clamps 12 simultaneously clamping or loose Open the two clamps (release is by means of the spring force of the sub-spring) so that the screw 16 can be rotated for knife-cutting or tool-holder change. by
