Automatic light mechanical arm

Abstract

The invention discloses an automatic light mechanical arm which comprises a base, a driving fixed seat and a mechanical arm. A control main center is fixed on the base. A power line interface is mounted on one side of the control main center. The driving fixed seat is connected with the control main center. A fixed cover fixed through a driving device is arranged on the driving fixed seat. The mechanical arm is connected with the driving fixed seat through a third rotating structure. A first rotating structure is connected to the upper part of the mechanical arm through a buckle. An expansion link is arranged at the front part of an expansion structure. A rotating shaft is mounted at the front end of the expansion link. A second rotating structure is arranged at the front part of the rotating shaft. A front end device is fixed on the second rotating structure. The automatic light mechanical arm is compact in structural design, the moving arm with the expansion structure is adopted, the gravitational torque is reduced, the flexibility of the mechanical arm is improved, an arm and a vertical column are prevented from being stuck, machine manufacturing can be conducted well, and development of the mechanical arm industry is promoted.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to an automated lightweight mechanical arm. Background technique [0002] The robotic arm is currently the most widely used automated mechanical device in the technical field. It can be seen in the fields of industrial manufacturing, medical treatment, military and space exploration. Although they each have different shapes and characteristics and play different roles, they all have one thing in common, that is, they can accept instructions and precisely locate a certain point in a three-dimensional or two-dimensional space to perform operations. With the rapid development of modern industrial production, manipulators are widely used. It plays a very important role in stabilizing, improving product quality, improving production efficiency, improving working conditions and rapid product replacement. There are many products around us that use robotic arms to improve our...

Problems solved by technology

[0004] The object of the present invention is to provide an automatic light and handy mechanical arm to solve the problem that the partial gravity moment proposed in the above background technology is very unfavorable to the movement of the arm. If the partial gravity moment is too large, it will cause the vibration of the arm, and a kind of heavy moment will also occur when lifting and lowering. The head phenomenon will also affect the flexibility of movement. In severe cases, the arm and the column will be stuck and other problems.
