现在介绍一种结构简单、使用方便的牛头刨床自动抬刀装置。这个装置如附图所示。图中1是支架,用螺钉固定在床身上。2是齿轮,3是垫圈,4是弹簧,它们一同套在轴5上,用螺帽6紧固在一起调整螺帽6可以使齿轮得到不同的摩擦压力。7是跟齿轮啮合的齿条。8是档销,用来防止工作时齿条跟齿轮的脱落。在齿条的一端,镶有向下弯曲的拉杆9,通过螺杆10跟装刀的拍扳连在一起。在拍板顶面固定一个档板11和螺钉12,当刨刀抬起一定位置,它便跟螺钉13接触。这个装置的工作原理是这徉的:当滑枕和刨刀空返回程时(见附
Now introduce a simple structure, easy to use shaper automatic lift device. This device is shown in the attached figure. Figure 1 is a bracket, with screws fixed to the bed. 2 is a gear, 3 is a washer, 4 is a spring, which together set in the shaft 5, with the nut 6 tighten the nut 6 can be adjusted so that the gears get different friction pressure. 7 is engaged with the gear rack. 8 is the dowel pin, used to prevent the work rack with the gear off. At one end of the rack, inlaid with downward bending rod 9, through the screw 10 with the knife attached to the pull plate. A clapper 11 and a screw 12 are fixed on the top of the clapper, and when the planer lifts a certain position, it comes in contact with the screw 13. The working principle of this device is this: when the ram and the planer empty back to return (see attached
