剪板机是一种应用较广的金属板料剪切加工机械。这种加工机械对剪料尺寸的控制是靠改变挡料板与剪切刀具的相对距离来保证的,如图1所示。目前生产的剪板机的尺寸调节机构是采用人工移动挡料板,用直尺等工具配合,实际测量挡料板的移动距离。每更换一次剪料尺寸,操作人员都要反复调节挡料板,并且反复实测位置尺寸才能准确定位。显然这种调
Shears is a widely used sheet metal shearing machine. This processing machinery for cutting size control by changing the relative distance between the stop plate and the cutting tool to ensure that, as shown in Figure 1. The current production of the shears size adjustment mechanism is the use of artificial moving block, with ruler and other tools, the actual measurement of the moving distance of the plate. For each change of cut size, the operator must repeatedly adjust the stop plate, and repeated measurements of position size can be accurately positioned. Obviously this tune
