一些加工精度要求较高、工步较多的回转体工件在车床上加工,必须借以辅助工夹具才能实现。为此设计了偏心夹紧快换刀架(见右图)。本辅具主要由刀架体、刀座及偏心夹紧部件组成。刀架体上没有两个60°凸燕尾,可与刀座相配合。若水平转动手柄,就会使偏心轴带动卡紧轴在刀架体内伸缩,从而达到卡紧或松开刀座的目的,以适应各种不同加工的需要。刀座上没有微调螺母及锁紧螺母,便于调整刀头的高低,使刀尖与车床主轴回转中心等高。
Some processing requirements of higher precision, more work-step rotary body parts in the lathe processing, you must rely on auxiliary fixtures can be achieved. For this reason, eccentric clamping fast tool changer design (see right). The main tool consists of knife body, knife block and eccentric clamping components. There are no two 60 ° convex dovetails on the knife body, which can be matched with the knife holder. If the handle is rotated horizontally, the eccentric shaft will drive the chucking shaft to telescope in the tool holder body so as to achieve the purpose of clamping or releasing the tool holder to meet the needs of various processing. Knife seat without fine-tuning nuts and lock nuts, easy to adjust the level of the head, so that the tip and lathe spindle rotation center contour.
