在牛头刨床上加工零件,在刨刀来回一次行程中,只能进行一次切削。为了提高刨床的生产效率,可以采用双头刀排和改装机床的走刀机构,这种方法是简单易行的。双头刀排的结构如图1所示。刀杆体1直接夹紧在机床的刀架上,在刀杆体1上有一圆梢5;圆梢5上套有要以转动的刀杆体4和6。刀杆体4和6中,装有左、右刨刀,用螺钉2来固定。调整螺钉3,可使左、右刨刀的两个切削刀刃,在同一平面上。当左面刨刀进行切削时,右面的刨刀就偏开不参加切削工作;反之,当右面的刨刀进行切削时,左面的刨刀就偏开。这样两把刨刀是按刀架运动方向,
In the shaper processing parts, a trip back and forth in the plane, only one cut. In order to improve the production efficiency of planer, you can use double-headed knife row and modified machine tool walk mechanism, this method is simple and easy. Double-headed knife structure shown in Figure 1. The cutter bar body 1 is directly clamped on the tool holder of the machine tool, and has a round tip 5 on the cutter bar body 1; the cutter body 4 and 6 to be rotated are sheathed on the round tip 5. Arbor body 4 and 6, equipped with left and right shaver, with screws 2 to be fixed. Adjust the screw 3 so that the two cutting edges of the left and right planer blades are in the same plane. When the left planing cutter is cutting, the right planer is offset to not participate in the cutting work. Conversely, when the right planer is cutting, the left planer is deviated. This two planer blade knife is the direction of movement,
