Problems solved by technology

[0003] In the course of our study of "Mechanical Design" and "Mechanical Principles", when explaining various transmission mechanisms, teachers often use the simplest teaching aids or directly explain the theory, which is not intuitive
However, the comprehensive training devices designed by some teaching instrument companies are more expensive and take up a lot of space, making it inconvenient for each student to carry out operation training independently

Embodiment 2

[0045] Embodiment 2 A new type of comprehensive demonstration teaching aid, refer to the structure figure 1 and 2 As shown, the difference from Example 1 is that the demonstration mechanism is a belt transmission mechanism, and the structure refers to Figure 4 shown. The belt transmission mechanism consists of a driving wheel 4-1-1, a driven wheel 4-1-2, a tensioning wheel 4-1-3, a synchronous belt 4-1-6 and a DC motor 4-1-7; the driving wheel One 4-1-1, driven wheel one 4-1-2 and tensioning wheel 4-1-3 are respectively fixed on the base 6 by fixture one 4-1-4; driving wheel one 4-1-1, slave Driving wheel one 4-1-2 and tensioning wheel 4-1-3 are connected with fixed piece one 4-1-4 through connecting shaft 4-1-5; the output shaft of DC motor 4-1-7 is through coupling It is connected with the connecting shaft of driving wheel one 4-1-1; driven wheel one 4-1-2 and driving wheel one 4-1-1 are connected through synchronous belt 4-1-6; tensioning wheel 4-1-3 Used to realize th...

Embodiment 3

[0046] Embodiment 3 A new type of comprehensive demonstration teaching aid, refer to the structure figure 1 and 2 As shown, different from Example 1,

[0047] The demonstration mechanism is a gear transmission mechanism, and the structure refers to Figure 5 shown. The gear transmission mechanism includes a gear one 4-2-1, a fixing part two 4-2-2, a motor and a base 6; a total of four gears one 4-2-1, which are fixed on the fixing part two 4-2-2 by a top screw On the four rotating shafts, four of the gears one 4-2-1 are scattered on the two fixed parts 4-2-2, and the adjacent gears one 4-2-1 mesh with each other; the motor is located on the two fixed parts 4-2-2. - On the rear side of 2-2, the output shaft of the motor is connected to the rightmost shaft through a coupling; driven by the motor, it drives the rightmost gear to rotate, and then drives the other three gears to drive to achieve demonstration Effect.

Abstract

The invention discloses a novel comprehensive demonstration teaching aid, which comprises a fixing table, a rotating mechanism, a lifting mechanism, a demonstration mechanism and a control mechanism;the rotating mechanism, the lifting mechanism and the control mechanism are arranged on the fixing table; the lifting mechanism is located on one side of the rotating mechanism; the demonstration mechanism is fixed on the base, and the control mechanism is used for controlling the rotating mechanism, the lifting mechanism and the demonstration mechanism to perform corresponding actions. The selected demonstration mechanism is rotated to a position right above the lifting mechanism through the rotating mechanism, and then is lifted to a certain height under the driving of the lifting mechanismfor demonstration. The lifting mechanism supplies power to each demonstration mechanism, so that each demonstration mechanism can be automatically controlled in the demonstration process; according tothe comprehensive demonstration teaching aid provided by the invention, mechanical control and automatic control are combined, and the learning interest of students can be stimulated.

Description

technical field [0001] The invention relates to the technical field of teaching aids, in particular to a new type of comprehensive demonstration teaching aid. Background technique [0002] At this stage, higher vocational education has further strengthened the cultivation of students' practical ability, so the requirements for teaching aids and skills are getting higher and higher. For students majoring in mechanical and electrical engineering, the requirement for teaching aids is the basic knowledge of skills learning, and it can also improve students' professional ability, practical ability and innovation ability. [0003] In the course of our study of "Mechanical Design" and "Mechanical Principles", when teachers explain various transmission mechanisms, they often use the simplest teaching aids or explain theories directly, which is not intuitive. However, the comprehensive training devices designed by some teaching instrument companies are more expensive and take up a l...
