Problems solved by technology

[0004] First, most of the experimental tables are assembled and fixed into the whole machine. Students can't assemble them individually according to their own needs. They can only learn by observing, and the learning effect is poor.
[0005] Second, in order to allow students to learn more types of mechanical transmission methods, the current experimental table often has a complicated mechanical transmission structure, and the structure is fixed, so the transmission of some parts is inconvenient to observe.
[0006] Third, the current experimental tables generally have a single function, and can only learn one course, such as mechanical transmission or hydraulic transmission, but not both. On the one hand, it is inconvenient for students to learn, and on the other hand, it increases teaching costs.

Embodiment 1

[0058] like figure 1 As shown, an experimental table used in the study of mechanical majors includes a table body 1, and the rear upper corners of the left and right sides of the table body 1 are respectively fixedly provided with connecting plates 11 by welding. A desktop 2 is arranged between the two connecting plates 11 .

[0059] like figure 2 and image 3 As shown, first rollers 12 are respectively provided on the inner surface of the connecting plate 11 (with the opposite side of the two connecting plates 11 as the inner side), and the left and right sides of the desktop 2 are respectively provided with rollers corresponding to the two rollers. The first roller 12 matches the chute 21.

[0060] like figure 2 and Figure 5 As shown, the back side of the desktop 2 is fixedly provided with a mechanical transmission learning unit 3 for learning the mechanical transmission structure (with figure 1 The orientation shown in , the back side mentioned here is the lower si...

specific Embodiment approach

[0070] As a specific implementation, the specific connection structure between each transmission mechanism and the screw transmission mechanism in this embodiment is:

Abstract

The invention discloses an experiment table applied to machinery major learning. The experiment table comprises a table body, and a table top is slidably hinged to the upper end of the table body. A machinery transmission learning unit is fixedly arranged on the back face of the table top, and a hydraulic transmission learning unit is arranged inside the table body. The hydraulic transmission learning unit can be lifted and lowered along the table body through a lifting mechanism. The machinery transmission learning unit comprises a first installation plate, a transmission piece and a supporting assembly used for supporting the transmission piece are arranged on the first installation plate. The transmission piece comprises a rotary shaft, a straight gear, a helical gear, a bevel gear, a synchronous pulley, a synchronous belt, a chain wheel, a chain, a worm gear, a worm, a lead screw and a nut. The experiment table is compact in structure, the operation is simple, machinery transmission learning and hydraulic transmission learning are achieved, students can perform personalized assembly according to the demand, and the learning effect is improved.

Description

technical field [0001] The invention relates to the technical field of teaching aids, in particular to an experiment table used in mechanical specialty learning. Background technique [0002] Mechanical transmission mechanism and hydraulic transmission are basic courses for mechanical majors, and they are the key points in the learning process of mechanical majors, and are widely used in mechanical design and industrial production. [0003] But for the new students, the mechanical transmission mechanism and hydraulic transmission are still relatively unfamiliar, there is no concept in their minds, and the content in the textbook is superficial, students cannot learn the knowledge intuitively, the learning effect is not good, and they are easy to forget. Therefore in order to enable students to learn more intuitively, many experimental tables have been invented at present. But present experimental table mainly has the following problems. [0004] First, most of the experime...
