Embodiment Construction

[0020] As shown in the figure, the superimposed double-parameter clam line diagram includes: the first parameter slider 1, the asymptote slider 2, the pole positioning lever 3, the radial rotation lever 4, the second parameter slider 5 and the branch line brush 6. The first parameter slide bar 1 is a rectangular slide bar with grooves, the asymptote slide bar 2 is plugged into one end of the first parameter slide bar 1, and the pole positioning bar 3 is slidably connected to the first parameter slide bar. On the rod 1, one end of the radial rotating rod 4 is rotatably connected to the pole positioning rod 3, and the slider on it is slidably connected to the asymptote sliding rod 2, and the second parameter sliding frame 5 is placed on the radial rotating rod. On the bar 4, the branch line brushes 6 are respectively placed on the second parameter sliding frame 5.

[0021] like figure 2 As shown, the first parameter slider 1 includes a first rectangular plate 11, a second rect...

Abstract

The invention discloses an overlapped two-parameter conchoid drawing gauge which comprises a first parameter sliding rod, an asymptote sliding rod, a pole positioning rod, a radial rotating rod, a second parameter sliding frame and branch line drawing pens. The asymptote sliding rod is inserted into one end of the first parameter sliding rod, the pole positioning rod is connected to the first parameter sliding rod in a sliding mode, one end of the radial rotating rod is rotationally connected to the pole positioning rod, a sliding block on the radial rotating rod is connected to the asymptote sliding rod in a sliding mode, the second parameter sliding frame is arranged on the radial rotating rod, and the branch line drawing pens are arranged on the second parameter sliding frame. The overlapped two-parameter conchoid drawing gauge has the advantages that the operation is easy, and all functions can be fulfilled in the mode that a user only needs to push handles; the functions are complete, the drawing gauge can be rapidly constructed, conchoid graphs with any parameters can be drawn, the multiple conchoid graphs can be drawn at the same time, and parameter adjustment is easy, convenient, rapid and random; the overlapped two-parameter conchoid drawing gauge is compact in structure, low in cost and convenient to carry, and a straight ruler is formed after the overlapped two-parameter conchoid drawing gauge is folded; and the overlapped two-parameter conchoid drawing gauge is high in applicability and can be used in any occasion; and the overlapped two-parameter conchoid drawing gauge is suitable for teaching, designing, manufacturing and the like.

Description

Technical field: [0001] The invention relates to a teaching tool, in particular to a superimposed double-parameter mussel line diagram gauge. Background technique: [0002] The clam line is also called the Nicomides clam line. The clam line formed by straight lines is the most commonly used figure. It is widely used in agriculture, communication, manufacturing and other industries. It is a must-have content for college and middle school students. The coordinate equation is ρ=aseθ±b, and the rectangular coordinate equation is (x-a) 2 (x 2 +y 2 ) = b 2 x 2 , because it is a curve composed of two points on a straight line and another straight line non-orthogonal motion, there are two parameters, the appearance is simple and the essence is complex, which makes it difficult for teachers to teach or students to learn, and seriously affects the teaching effect . In addition, engineering designers draw drawings and machining personnel process parts, etc., all need fast and con...
