在实际工作中,常遇到制作椭圆。为了简便地在图纸上、工件上画出椭圆,经过反复实践,我们制作了一种简易椭圆规。一、结构简介如图1所示,规体1上开有十字滑槽,三个定位钉2均布在规体1的圆周上,上滑块3、上磁环4、下滑块10、下磁环8、螺母7和轴5组成滑块A、B,划针5可上下调节,由紧定螺钉固定。当推动划针6时,滑块A在
In practical work, often encounter the production of oval. In order to draw an oval on the drawing and workpiece easily, we made a simple elliptical rule after repeated practice. First, the structure profile As shown in Figure 1, there is a cross on the regulatory body 1 Chute, three positioning nails 2 are arranged on the circumference of the regulatory body 1, the slider 3, the upper ring 4, the lower slider 10, The lower magnetic ring 8, the nut 7 and the shaft 5 form a slider A, B, and the scribing needle 5 can be adjusted up and down and fixed by a set screw. Slider A is on when scribe 6 is pushed
