为使螺纹偏心夹紧式车刀的刀片与偏心轴产生偏移,偏心销直径和夹紧点选择合理,并使夹紧点落在一定范围内,对夹紧形式进行了改进。解决了一般螺纹偏心结构V型槽定位,刀片不能同时被夹紧在两个定位面上(一个定位面有缝隙)的缺点,使切削性能大有提高。结构的改进:如图1所示。1.刀体选用V形槽定位:刀体选用V形槽作为刀片的定位,是一个比较理想的形式。它具有两个相交的定位平面和底面的支承,可有效地限制刀片在刀体上的六个自由度,结构选择合理会消除刀片在切削过
In order to offset the eccentric eccentric shaft and the cutter blade of the eccentric eccentric clamping tool, the eccentric pin diameter and the clamping point are selected reasonably, and the clamping point falls within a certain range, the clamping form is improved. The utility model solves the disadvantage that the general thread eccentric structure V-shaped groove is positioned, the blade can not be clamped at the two positioning surfaces at the same time (the gap of a positioning surface is provided), and the cutting performance is greatly improved. Structural improvements: Shown in Figure 1. 1. The use of V-shaped knife body positioning: V-shaped knife body as the blade positioning, is a more ideal form. It has two intersecting positioning plane and the bottom of the support, which can effectively limit the blade in the body of the six degrees of freedom, a reasonable choice of structure to eliminate the blade in the past
