Abstract
A demonstration teaching aid of a higher mathematics revolution surface belongs to the teaching auxiliary tool field, and solves the problem that right now no revolution surface demonstration teaching aid is available for teachers and students. The demonstration teaching aid comprises a pedestal, a motor, a rotating shaft, two clamps and a bus. The motor is fixed on a base plate of the pedestal; a lower end of the rotating shaft penetrates through a circular hole on a top board of the pedestal and fixedly connects a top end of the rotating shaft of the motor; the two clamps are formed by a front end of a telescopic rod fixedly connected with clips; a rear end of the telescopic rod of the two clamps is fixedly connected with the rotating shaft; the two clamps are arranged over the top board, are parallel to each other, and are separately arranged at the same side of the rotating shaft; the bus is a copper wire which is coated with fluorescent paint on a surface; and the bus is clamped by clips on the two clamps. The demonstration teaching aid of the utility model is used for demonstrating the revolution surface in the higher mathematics teaching, and can demonstrate the process of the bus rotating around the rotating shaft to form the revolution surface, so that the students can rapidly understand the revolution surface.
Description
Technical field
The utility model belongs to the teaching tool field, is specifically related to a kind of higher mathematics surface of revolution demonstration teaching aid.
Background technology
Demonstration teaching aid can be deepened the student to the understanding of the content of courses, surface of revolution is the part of University Space cartesian geometry, fully understand and to grasp surface of revolution very important, but the teaching aid of also not demonstrating so far surface of revolution makes troubles for teachers' instruction and Students ' Learning for teachers and students.
Summary of the invention
Order of the present utility model ground is also not demonstrate so far the teaching aid of surface of revolution for teachers and students' problem in order to solve, and a kind of higher mathematics surface of revolution demonstration teaching aid is provided, and its technical scheme is as follows:
A kind of higher mathematics surface of revolution demonstration teaching aid, it comprises base, motor, turning axle, two anchor clamps and bus; Described base is fixedly connected with by four root posts with top board by base plate and consists of, and leaves circular hole in the middle of the described top board; Described motor is fixedly connected on the base plate of base, and motor is positioned at the centre of base plate, and the rotating shaft of motor arranges vertically upward; The circular hole that the lower end of described turning axle is passed on the top board of base is fixedly connected with the rotating shaft top of motor, and turning axle is vertical with top board to be arranged, and turning axle and top board intersection are dynamically connected by bearing rotary; Described two anchor clamps all are fixedly connected with clip by the expansion link front end and consist of, and the expansion link rear end of two anchor clamps is fixedly connected with turning axle, and two anchor clamps all are positioned at the top of top board, and two anchor clamps are parallel to each other up and down and are arranged at phase the same side of turning axle; Described bus is the copper wire that a surface scribbles fluorescent paint, and bus is by the clamp on two anchor clamps.
Preferably: described motor is adjustable speed motor.
The beneficial effects of the utility model are: can demonstrate bus around the process of turning axle formation surface of revolution, make student's fast understanding surface of revolution.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
With reference to Fig. 1, a kind of higher mathematics surface of revolution demonstration teaching aid, it comprises base 1, motor 2, turning axle 3, two anchor clamps 4 and bus 5; Described base 1 is fixedly connected with by four root post 1-3 with top board 1-2 by base plate 1-1 and consists of, and leaves circular hole in the middle of the described top board 1-2; Described motor 2 is fixedly connected on the base plate 1-1 of base 1, and motor 2 is positioned at the centre of base plate 1-1, and the rotating shaft 2-1 of motor 2 arranges vertically upward, and motor 2 is adjustable speed motor; The circular hole that the lower end of described turning axle 3 is passed on the top board 1-2 of base 1 is fixedly connected with the rotating shaft 2-1 top of motor 2, and turning axle 3 arranges with top board 1-2 is vertical, and turning axle 3 is dynamically connected by bearing rotary with top board 1-2 intersection; Described two anchor clamps 4 all are fixedly connected with clip 4-2 by expansion link 4-1 front end and consist of, the expansion link 4-1 rear end of two anchor clamps 4 is fixedly connected with turning axle 3, two anchor clamps 4 all are positioned at the top of top board 1-2, and two anchor clamps 4 are parallel to each other up and down and are arranged at phase the same side of turning axle 3; Described bus 5 is the copper wire that a surface scribbles fluorescent paint, and bus 5 is clamped by the clip 4-2 on two anchor clamps 4.
Using method and principle: the copper wire ratio is easier to bend to arbitrary shape, first bus 5 is bent to the shape that needs, expansion link 4-1 on two anchor clamps 4 is adjusted to respectively the length that needs, again the clip 4-2 on two anchor clamps 4 of bus 5 usefulness is clamped, start motor 2, speed is observed bus 5 forms surface of revolution around turning axle 3 process from slow to fast.The surface of bus 5 scribbles fluorescent paint, and the surface of revolution that bus 5 rotations are formed is more eye-catching.
