Three-freedom-degree controllable mechanical manipulator

Abstract

The invention discloses a three-freedom-degree controllable mechanical manipulator, and belongs to the field of manipulators. The three-freedom-degree controllable mechanical manipulator is characterized in that a first shaft, a second shaft and a third shaft are connected with a first controllable motor, a second controllable motor and a third controllable motor on a machine frame respectively; the first shaft and the second shaft are hollow shafts; the second shaft is sleeved with the first shaft; the third shaft is a solid shaft and sleeved with the second shaft; the first shaft is fixedly connected with a first gearbox, the first gearbox is installed in a second gearbox to achieve linkage, and the head of the manipulator can rotate by 360 degrees through the first controllable motor. The other end of the second shaft is in key connection with a first driving bevel gear, the first driving bevel gear is engaged with a first driven bevel gear, the first driven bevel gear is connected with the second gearbox, and the head of the manipulator can swing by 180 degrees vertically through the second controllable motor. The other end of the third shaft is in key connection with a second driving bevel gear, the second driving bevel enables a first short shaft, a second short shaft and a third short shaft to rotate by driving a driven gear, and clamping movement of a swing rod, an upper claw and a lower claw is achieved. The three-freedom-degree controllable mechanical manipulator has the advantages of being simple in structure, safe and reliable.

Description

technical field [0001] The invention belongs to the technical field of manipulators, and in particular relates to a three-degree-of-freedom controllable mechanical manipulator. Background technique [0002] With the continuous development of modern industry and the improvement of mechanization and automation level of production process, manipulators have been more and more widely used in mechanical processing, assembly processing, light industry, transportation and other fields. In actual production, the application of manipulators can improve the automation level of production, thereby improving labor productivity. In harsh environments, manipulators can replace humans to work, which can reduce labor intensity, ensure product quality, and achieve safe production. [0003] At present, the manipulators traditionally used at home and abroad have complex structures, low efficiency, insufficient strength, high maintenance costs, and cannot flexibly grip objects in large spaces....
