Embodiment 1

[0047] Such as image 3 As shown, the electrical box is installed at the end of the three-dimensional frame, the driving motor is installed on the two short beams in the middle of the bottom frame, and the connecting shaft is installed at the position of the three-dimensional frame above the left obliquely above the driving motor. V-belt pulleys are arranged on the shaft respectively, and the two V-belt pulleys are connected by a belt to form a belt transmission mechanism. Turn on the power switch of the electrical box and adjust the motor debugging knob to make the drive motor drive the belt transmission mechanism to run. Install another connecting shaft at a suitable position on the three-dimensional frame, and install a large spur gear and a small spur gear on the two connecting shafts to form an external gear mechanism. The external gear mechanism can run together with the belt transmission mechanism. The bearing support is installed on the cross beam of the bottom frame, ...

Embodiment 2

[0049] Such as Figure 4 As shown, the worm gear and worm mechanism are installed on the three-dimensional frame above the driving motor through the bearing support, and the small bevel gear is connected to the end of the worm, and the large bevel gear is fixed on the three-dimensional frame through the connecting shaft, and connected with the small bevel gear The conical gear mechanism is formed by meshing with each other. At the same time, a V-belt pulley is installed on the connecting shaft of the large bevel gear, and a V-belt pulley is installed coaxially with the output shaft of the driving motor. The two V-belt pulleys are connected by a belt to form a new one. belt drive mechanism.

Embodiment 3

[0051] Such as Figure 5 As shown, the mechanical structures of embodiment 1 and embodiment 2 are connected through the belt transmission mechanism, and the motor is driven to move, and the belt transmission mechanism of embodiment 1 is driven to operate while the belt transmission mechanism of embodiment 2 can also be driven to operate. Embodiment 2 The operation of the belt transmission mechanism can drive the operation of the conical gear mechanism, and the operation of the conical gear mechanism drives the operation of the worm gear mechanism.

Abstract

The invention discloses a simple assembling experiment device for teaching based on a three-dimensional space mechanism. The assembling experiment device comprises a three-dimensional rack, a plurality of groups of matched mechanical structures, a driving motor and an electrical box, the mechanical structure, the driving motor and the electrical box are all detachably arranged on the three-dimensional rack, the driving motor is electrically connected with the electrical box and used for driving the mechanical structure to act, and a motor debugging button and a power switch are installed on apanel of the electrical box. A belt transmission mechanism, an outer gear mechanism, a swing guide rod mechanism, a gear and rack mechanism, a worm and gear mechanism, a conical tooth mechanism, a parallelogram mechanism, a crank rocker sliding block mechanism and a Maltese grooved pulley mechanism are integrated. A plane mechanism and a space mechanism can be assembled according to actual needs,the mechanical innovation consciousness of students can be enhanced, and the mechanical comprehensive design capacity is improved.

Description

technical field [0001] The invention belongs to the technical field of mechanical design experiment teaching supplies, and in particular relates to a simple assembling experiment device for teaching based on a three-dimensional space mechanism. Background technique [0002] The most prominent problems in the quality of current talent training are mainly reflected in the lack of students' practical ability and lack of innovative spirit. Therefore, it is particularly important to cultivate students' innovative spirit and innovative ability through practical courses in teaching. Mechanism assembly is one of the most basic ways of mechanical innovation design. Setting up space mechanism assembly experiment is an effective measure to cultivate students' mechanical innovation consciousness and innovation ability. [0003] The backwardness of institutional assembly experimental equipment is a major obstacle to the cultivation of students' innovative thinking and innovative ability...
