A four-bar mechanism teaching aid for teaching the principle of mechanical movement

Abstract

The invention relates to a four-bar mechanism teaching tool for mechanical motion principle teaching used for the subjects of machine design, mechanical principle, mechanics of materials and college physics. The four-bar mechanism teaching tool for mechanical motion principle teaching is used for helping the students for understanding and observing the mechanical motion with changeful movement and complex track. According to the technical scheme, four pier bases are connected with four corners under the chassis, the chassis is provided with three grooves used for mounting the L-shaped rod and the rod with the shape of Chinese character Tu, a sliding block is sleeved at the lower part of the rod with the shape of Chinese character Tu; a cam is connected with the rod with the shape of Chinese character Tu and a crank A through the bolts; a concave block is bonded to the upper end of the rod with the shape of Chinese character Tu, a push rod is inserted in the concave block, the other end of the crank A is connected with the disc, the rocking bar B and the rocking bar A; the rocking bar A is connected with the sliding block, the rocking bar B is connected with the crank B, the crank B is connected with the upper end of the L-shaped rod, the middle of the L-shaped rod is provided with the cross to be sleeved in two sliding blocks; a guide rod is inserted in the guide block and connected with the rod with the shape of Chinese character Tu, a crank C is connected with the rocking bar C and the guide block. The four-bar mechanism teaching tool adopts the combined type of a variety of institutions; the action of the mechanism is clear, legible, true, convenient and labor-saving.

Description

[0001] Technical field: [0002] The invention relates to a four-bar mechanism teaching aid for the principle of mechanical movement, which is especially suitable for subjects related to the teaching content of the principle of mechanical movement, such as: mechanical design foundation, mechanical principle, mechanical design, material mechanics, university physics and other subjects. Demonstration and explanation of sports related knowledge. [0003] Background technique: [0004] With the development of science and technology, when teachers explain the movement mechanism to students, it is often difficult to give students an intuitive description by simply narrating. To give students the most intuitive feeling and understanding, relying on pictures and explanations is also helpful. Difficulty, so teaching aids are very necessary. All subjects need teaching aids to a certain extent, especially the courses related to machinery. The movement of machinery is changeable and the t...

Problems solved by technology

However, simple production will waste resources and increase costs. Therefore, we imagined that the teaching aids of the four-bar mechanism can be multi-functional, save materials, and use one thing for multiple purposes.
