我们在曲轴生产流水线的梯级滚道输送带上安装了一台简易气动提升机。结构如图所示。在静止状态,手动配气阀在中间位置。当零件从第一级滚道上自由落下,掉入提升钩11中时,利用重力压下提升钩,撞块3压下配气阀手柄4,使配气阀换向。气缸7即推动旋转提升钩开始向上运动。当提升钩运动到一定位置时,零件靠自重向第二级滚道滚去。此时撞块5向上拨动配气阀手柄4,配气阀 We installed a simple pneumatic lift on the cascade roller conveyor on the crankshaft production line. Structure as shown. In the quiescent state, the manual gas distribution valve is in the middle position. When the parts fall freely from the first stage raceway and fall into the lifting hook 11, the lifting hook is pressed down by gravity, and the impact block 3 depresses the valve handle 4 to change the valve. The cylinder 7 is pushed to rotate the lifting hook to start the upward movement. When lifting the hook to a certain position, the part by gravity to the second level raceway to go. At this time block 5 upward dial valve handle 4, with valve
