Six-degree-of-freedom hydraulic mechanical arm

Abstract

The invention discloses a six-degree-of-freedom hydraulic mechanical arm, and belongs to the technical field of mechanical equipment. The six-degree-of-freedom hydraulic mechanical arm comprises a base rotary joint, a big arm, a first telescopic joint, a first mechanical arm, a second telescopic joint, a second mechanical arm, a horizontal swing joint, a rolling swing joint, a rolling swing support, a pitching joint and two bearing assemblies; one end of the big arm is fixed to the top surface of the base rotary joint, and the other end of the big arm is rotationally connected with one end ofthe first mechanical arm through the bearing assemblies; the other end of the first mechanical arm is rotationally connected with one end of the second mechanical arm, and the other end of the secondmechanical arm is fixedly connected with the horizontal swing joint; the rolling swing support is rotationally connected with the horizontal swing joint, the rolling swing joint is arranged on the inner side of the rolling swing support, and the pitching joint is rotationally connected with the rolling swing support; the two ends of the first telescopic joint are rotationally connected with the big arm and the first mechanical arm correspondingly, and the two ends of a second telescopic joint are rotationally connected with the first mechanical arm and the second mechanical arm correspondingly. According to the six-degree-of-freedom hydraulic mechanical arm, hydraulic driving is adopted, so that the working angle can be accurately adjusted.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, in particular to a six-degree-of-freedom hydraulic mechanical arm. Background technique [0002] In the modern machinery industry, automated mechanical equipment has replaced human labor in large quantities, and the work efficiency has been greatly improved. At the same time, it can operate in harsh environments to ensure personal safety. The robotic arm is the earliest automated industrial robot that can simulate certain movements of the human arm to grab and carry objects with a fixed program. If it is necessary to ensure the precise placement of objects, it cannot be done by a single robotic arm, resulting in the need for more auxiliary devices. At present, a single industrial manipulator has few degrees of freedom and cannot complete transmissions that require higher precision. Therefore, improving the degree of freedom of the joints of the manipulator is an urgent problem to be ...

Problems solved by technology

The robotic arm is the earliest automated industrial robot that can simulate certain movements of the human arm to grab and carry objects with a fixed program. If it is necessary to ensure the precise placement of objects, it cannot be done by a single robotic arm, resulting in the need for more auxiliary devices. At present, a single industrial manipulator has few degrees of freedom and cannot complete transmissions that require higher precision. Therefore, improving the degree of freedom of the joints of the manipulator is an urgent problem to be solved.

Moreover, at present, most of the mechanical arms in the industry are driven by electricity, which has the disadvantages of high cost and high maintenance requirements.
