1.单工位刀架 本刀架主要由刀体2、刀夹1及偏心夹紧3等部件组成,见图1。刀体上有60°凸燕尾,与刀夹配合,根据加工需要可选择图2中任一刀夹(a)或(b)或自备刀夹。切削刀具和钻头装在同一装置中能快速调换和正确定位。利用偏心轴3的旋转产生的自锁能力及支销和拉簧的作用,能牢固的夹紧刀夹,并起到刀夹的夹紧或松开的目的。为适应各种不同加工的需要,刀垫上设有两个微调部分,便于调整刀头的高低,使刀夹与车床主轴回转中心等高。
1. Single-station tool holder The tool holder is mainly composed of the tool body 2, the tool holder 1 and eccentric clamping 3 and other components, see Figure 1. There is a 60 ° convex dovetail on the blade body, which cooperates with the tool holder to select any one of the tool holder (a) or (b) or self-contained tool holder in Figure 2 according to the processing needs. Cutting tools and drill bit installed in the same device can quickly exchange and correct positioning. By utilizing the self-locking ability generated by the rotation of the eccentric shaft 3 and the action of the support pin and the extension spring, the tool holder can be firmly clamped and the purpose of clamping or releasing the tool holder can be achieved. In order to meet the needs of a variety of different processing, the knife has two fine tuning part, easy to adjust the level of the blade, the tool holder and lathe spindle rotation center contour.
