如图所示:斜齿圈2紧卡在刀架转盘上,装有手轮1,棘轮11、拨爪10的蜗杆9装在滑忱头端,和斜齿圈2啮合,在滑忱的中段装有挡板5和挡板架4,连杆3的两头滑套在挡板5和拨爪体12的末端,在床身上部装有带挡块的导轴8。当滑忱回程结束时,挡块7碰开挡板5,通过连杆3拨动拨爪10使蜗杆9转动,蜗杆9又带动紧卡在刀架转盘上的斜齿圈2,使刀架转盘回转进刀。滑枕开始工作行程后,由于弹簧6的作用,挡板带动拨爪复位,依次往复循环自动进刀。
As shown in the figure, the bevel gear 2 is tightly clamped on the turret turntable and equipped with a hand wheel 1, a ratchet wheel 11 and a worm 9 of the claw 10 are arranged on the head end of the slippery wheel and engaged with the bevel gear 2, The middle section is provided with a baffle plate 5 and a baffle frame 4. The two ends of the connecting rod 3 are sleeved on the ends of the baffle plate 5 and the claw body 12, and a guide shaft 8 with a stopper is arranged on the upper part of the bed body. When the glory back to the end, the stopper 7 touch the baffle 5, through the connecting rod 3 toggle 10 to enable the rotation of the worm 9, the worm 9 and then drive tight clamped on the turret turntable ring 2, the turret Turntable rotary feed. After the ram begins to work stroke, due to the function of the spring 6, the bezel drives the resetting of the claw to be reset, and then the reciprocating feed is automatically repeated.
