Abstract
The utility model discloses a plotting instrument for higher mathematics teaching and relates to mathematics teaching instruments. The plotting instrument for the higher mathematics teaching comprises a base, wherein an annular counter weight is arranged at the bottom in the base, a rotary servo motor is arranged at the center position of the counter weight, a turntable is arranged on the top of the base, the rotating shaft of the rotary servo motor is connected with the central position of the turntable, a slide rail is arranged above the turntable, a nut is arranged in the slide rail, two sides and the bottom surface of the nut are in sliding fit with the slide rail, a mobile servo motor is fixed at one end of the slide rail, a screw rod is installed on the rotating shaft of the mobile servo motor, the screw rod is matched with a threaded hole of the nut, a plotting arm is fixed on the nut, a light drawing pen is fixed below the end portion of the plotting arm, and the rotary servo motor and the mobile servo motor are connected by a controller through a wire. The plotting instrument for the higher mathematics teaching solves the problems that in the process of university mathematics teaching, larger errors exist when a teacher draws graphics and curves with a hand so that the function curve and the shape of the graphics are non-standard, coordinate points and function values are hard to express accurately, and graphics drawing occupies the lecture time.
Description
Technical field
The utility model relates to structural apparatus, is specifically related to the Higher Mathematics Teaching drawing instrument.
Background technology
In College Mathematics Teaching, often need to draw some figures, curve etc.There is larger error in the figure of teacher's Freehandhand-drawing, causes the shape of function curve inaccuracy, figure nonstandard, and coordinate points and functional value also are difficult to accurate expression, can affect student's visual experience, further affect teaching efficiency.In addition, higher mathematics relates to the many kinds of function curve, and the classroom is now drawn and lost time.
The utility model content
The utility model provides the Higher Mathematics Teaching plotter, the utility model has solved in College Mathematics Teaching, there are larger error in teacher's hand-drawing graphics, curve, cause the shape of function curve inaccuracy, figure nonstandard, coordinate points and functional value also are difficult to accurate expression, and the existing graphing curve in the classroom problem such as lose time.
For addressing the above problem, the utility model adopts following technical scheme: the Higher Mathematics Teaching plotter comprises pedestal 1;
A slideway 5 is arranged on rotating disk 4, and slideway 5 is positioned at rotating disk 4 diametrical position, is provided with a nut 6 in slideway 5, forms between nut 6 both sides and bottom surface and slideway 5 to be slidably matched; Shift servo motor 7 is fixed in slideway 5 one ends, and screw rod 8 is installed in the rotating shaft of shift servo motor 7, and screw rod 8 matches with the screwed hole of nut 6;
Be fixed with a plotting hand 9 on nut 6, plotting hand 9 ends extend rotating disk 4 outsides, are fixed with a detail pen 10 below plotting hand 9 ends;
Also be fixed with controller 11 below rotating disk 4, be fixed with display and supervisory keyboard 12 in pedestal 1 outside, controller 11 connects rotating servo motor 3 and shift servo motor 7 by wire, and display and supervisory keyboard 12 are by wire connection controller 11.
The utility model is the multi-function drawing instrument that a kind of machine driving combines with electronic technology, by setting in advance the various higher mathematics function curves in controller, control two servomotors by controller, various function curves can be drawn out fast on chart board, coordinate points and functional value can be accurately given expression to.The teacher can go up on-the-spot graphing of class hour, so that the student understands intuitively; Can also be connected to and directly show use on liquid crystal display.
The utlity model has following advantage: graphing, curve are accurate, and shape criteria can accurate expression coordinate points and functional value, and plotting speed is fast, saves the teacher and draws the time.
