Description
Technical field
The utility model relates to a kind of drawing instrument, particularly the novel ellipse figure renderer of one.
Background technology
As everyone knows, the track being equaled the point of constant (be greater than | F1F2|) by the distance sum of two in plane fixed point F1, F2 is a closed curve, and this curve is called ellipse.These two fixed points are called oval focus, and the distance between bifocal is called focal length.Oval shape and size are by major semiaxis a, and semi-minor axis b, half focal length c determines.Wherein a
2=b
2+ c
2if, so know that in a, b, c, any two parameters just can determine oval shape and size.
A kind of comparatively popular recently, elliptical drawing tool, can draw oval gabarit.Actual content is exactly use three common use compasses, pair adds the preceding paragraph flexible fiber body, certainly a paintbrush to also be had, be stuck in this section of flexible fiber Nei Vela, mobile paintbrush draws the profile of ellipsograph, but the short slab that this kind of compasses are fatal, that flexible corpus fibrosum must have certain elasticity, insert flexible corpus fibrosum, drawing of oval gabarit is carried out with paintbrush, in drawing, also will do segmentation repeatedly, can think that paintbrush is in such profile describes, the accuracy of oval gabarit figure and the continuity of drawing line segment must be poor.
Conventional elliptical rule form by by the base plate of cross chute and swing arm.Cross chute is respectively equipped with a movable sliding table mark.A swing arm is had below slide sign.This swing arm is connected with two slide signs in length and breadth.Mobile slide sign, the turn that the swing arm below it can do 360 ° draws the ellipse meeting elliptic equation.Operation principle is exactly that lever connects two rotary pairs, and location guide connects two moving sets, and guide rod is cross, and in lever, each locus of points is the different ellipse of the line of apsides.
Traditional Ellipsograph structure is comparatively complicated, and the accuracy of manufacture requires higher, and metal material generally will be adopted just can to process, thus finished product is expensive, and draws larger ellipse, less ellipse, all depend on the yardstick of instrument itself, be difficult to the description adapting to all kinds of oval gabarit.
