我厂刨工同志在龙门刨床上试制成功专门刨内、外圆弧的简易机构,使用后认为操作方便,效果较好。现介绍于后。一、刨内圆弧机构结构如图1,以刀杆4为基体,旋转盘2的轴安装在刀杆的轴孔中,轴端用键与蜗轮7配合。刨刀1装在旋转盘的中心槽内,借螺钉及压板3固定。蜗杆支架5作为蜗杆6的轴承,它在刀杆上的位置依蜗杆与蜗轮的啮合而定。
I plant planing comrades in the planer trial planing the success of the plane, the outer arc of the simple body, after use that operation is easy, the effect is better. Now introduced later. First, the planer structure of the arc within the body shown in Figure 1, the arbor 4 as the base, the axis of the rotary plate 2 is mounted on the arbor of the arbor, the shaft end of the key with the worm gear 7. Planing knife 1 installed in the center of the rotary groove, by screws and platen 3 fixed. The worm support 5 serves as the bearing of the worm 6, and its position on the knife bar depends on the engagement of the worm and the worm wheel.
