经过观察,从刀架的动作过程中获得了启示,设计了一个十分简单的小型刨床自动抬刀装置。经过使用,证明效果很好,现简介如下。刨床自动抬刀装置结构如附图所示,它由安装套、销轴、抬刀块、紧套螺钉等组成。销轴和安装套为静配合,销轴和抬刀块为动配合,故抬刀块可绕销轴自由转动。使用时,将抬刀装置安装在刨刀上,调整抬刀块9低于刀尖2～4mm,然后用紧套螺钉固定。当刨刀向左移动进行刨削时,由于抬刀块9低于工件,故会被工件挡住而绕销轴逆时钟转动,可旋转到高出工件的位置,故不会影响刨削进行。当刨刀向右移动 After observation, the revelation was obtained from the movement of the knife holder, and a very simple small planer automatic lifting knife device was designed. After use, the effect is very good, are as follows. Planer automatic lifting device structure as shown in the figure, which consists of mounting sleeve, pin, lift knife block, tighten sets of screws and other components. Pin and mounting sleeve for the static fit, pin and lift the knife block with the dynamic fit, so lift the knife block can be freely rotated around the pin. When using, lift the knife device on the planer knife, adjust the lifting knife block 9 below the tip 2 ~ 4mm, and then tighten the set screws. When the planer moves to the left for planing, since the lifting block 9 is lower than the work piece, it will be blocked by the work piece and rotate counterclockwise around the pin axis so as to be rotated to a position higher than the work piece. Therefore, the planing will not be affected. When the planer moves to the right
