凸轮杠销式机夹不重磨车刀的结构,如图所示。当拧紧螺母时,杠销(图2)上R2.5×30°的圆弧斜面沿着刀体上R2.5×30°的圆弧槽向下移动,杠销带动刀片,迫使靠向刀体定位面,从而压紧刀片。这种结构的特点:简单、紧凑、夹紧可靠。对于四边形、五边形刀片同样可以采用此结构。注意事项:1.这种结构夹紧力大,使用时螺母不宜拧得太紧; Cam lever pin machine does not restoring the structure of the tool, as shown. When the nut is tightened, the R2.5 × 30 ° arc ramp on the bar pin (Figure 2) moves downward along the R2.5 × 30 ° arc slot on the blade body. The bar pin drives the blade to force the leaning knife Body positioning surface, which pressed the blade. The features of this structure: simple, compact, reliable clamping. For quadrilateral, pentagonal blade can also use this structure. Note: 1. This structure clamping force, the nut should not be used too tight when used;
