Mechanical arm for teaching demonstration

Abstract

The invention discloses a mechanical arm for teaching demonstration. The mechanical arm comprises a base, supporting feet are arranged at the lower end of the base, rolling wheels are arranged at thelower ends of the supporting feet, a first motor is arranged in the base, a first coupling is arranged at the upper end of the first motor, a first rotating shaft is arranged at the upper end of the first coupling, an output shaft of the first motor is connected with the first rotating shaft through the first coupling, a rotary table is arranged at the upper end of the first rotating shaft, two front-back opposite mounting plates are arranged at the upper end of the rotary table, and a second rotating shaft is arranged between the two mounting plates. The mechanical arm is simple in structureand convenient to use, angle adjustment on an arm rod of the mechanical arm can be achieved, the work direction of the mechanical arm is more comprehensive, and meanwhile the flexibility of work of the mechanical arm is enhanced; position change of the mechanism arm can be achieved, some special operation requirements of a user are met, great convenience is brought to the user, and teaching use isfacilitated.

Description

technical field [0001] The invention relates to the field of teaching technology, in particular to a mechanical arm for teaching demonstration. Background technique [0002] With the vigorous development and wide application of robot technology, the experimental teaching of robotic arms in colleges and universities has begun. However, due to the complex structure, large volume and difficult movement of commonly used robotic arms, they are not suitable for classroom use. In view of this situation, the present invention designs a mechanical arm for teaching demonstration with simple structure, convenient disassembly and assembly, and low cost. For example, the patent of application publication number 201611052044.4 discloses a mechanical arm for teaching demonstration, but the above There are some defects in the use of the patent. On the one hand, the movement of the mechanical arm device cannot be realized, and on the other hand, the movement of the mechanical arm is not flex...

Problems solved by technology

[0002] With the vigorous development and wide application of robot technology, the experimental teaching of robotic arms in colleges and universities has begun. However, due to the complex structure, large volume, and difficult movement of commonly used robotic arms, they are not suitable for classroom use.

In view of this situation, the present invention designs a mechanical arm for teaching demonstration with simple structure, convenient disassembly and assembly, and low cost. For example, the patent of application publication number 201611052044.4 discloses a mechanical arm for teaching demonstration, but the above There are some defects in the use of the patent. On the one hand, the movement of the mechanical arm device cannot be realized. On the other hand, the movement of the mechanical arm is not flexible enough, such as the direction of the mechanical arm rod cannot be adjusted.
