这个发明是利用液压把触指的运动传给刀具,同时也传给工作台进给机构,以便控制工作台的进给速度。图1是仿形铣床的示意图,这个发明的主要之点是图中用虚线围起来的部分,其它的部分和以前知道的仿形铣床一样。以前的仿形铣床工作台进给油缸是以一定的速度来驱动工作台的。四向换向回转阀按照触指的上下运动而回转,以此来控制刀具的上下运动。
This invention is the use of hydraulic pressure to contact the finger movement to the tool, but also passed to the table feed mechanism in order to control the table feed rate. Figure 1 is a schematic view of a profiling milling machine. The main point of this invention is the part enclosed by a dotted line in the figure, the other parts being the same as the profiling milling machine previously known. The previous copy milling table feed cylinder is driven by a certain speed table. Four-way reversing rotary valve in accordance with the finger up and down movement and rotation, in order to control the tool up and down movement.
