工作原理图1为一种利用圆弧楔块实现间隙旋转送进的机构。该机构应用广泛,结构简便,现介绍如下: 在图1中,当摆架1顺转时,夹紧力通过圆弧楔的楔角传至送进轮5,迫使送进轮顺转;当摆架反转时,送进轮通过反方向的楔角在圆弧上滑过而不能形成反转。以此循环完成间歇旋转送进。挡簧销3固定在摆架上顶着弹簧4的一端,弹簧另一端顶着可滑动的圆弧楔2,弹簧消除了楔面间隙,使楔面始终与摆架及送进轮接触,从而使运动自如。
Working principle Figure 1 is a use of arc wedge to achieve gap rotation feed mechanism. The mechanism is widely used, the structure is simple, are presented as follows: In Figure 1, when the swing frame 1 is turned clockwise, the clamping force is transmitted to the feed wheel 5 through the wedge angle of the arc wedge to force the feed wheel to rotate; When the pendulum is reversed, the feed wheel slides over the arc through the wedge angle in the opposite direction and can not form an inversion. This cycle to complete the intermittent rotation feed. The spring retainer pin 3 is fixed on one end of the swinging bracket against the spring 4. The other end of the spring is wedged against the circular arc wedge 2. The spring eliminates the wedging gap so that the wedging surface always contacts the swinging bracket and the feed wheel To exercise freely.
