Multi-freedom-degree hydraulically-driven mechanical hand used for carrying in workshops

Abstract

The invention relates to a multi-freedom-degree hydraulically-driven mechanical hand used for carrying in workshops. The mechanical hand has five freedom degrees and comprises a hand clamping mechanism, a wrist rotation mechanism, a telescopic arm mechanism and a machine body mechanism. The machine body mechanism comprises a base, a rotation cylinder, a lifting cylinder and a rotation arm. The rotation cylinder is arranged on the lifting cylinder. The hand clamping mechanism comprises grippers and a linear clamping hydraulic cylinder for driving the grippers to do clamping movement. The telescopic arm mechanism is a double-guide-rod telescopic arm structure. The wrist rotation mechanism is arranged at the front end of the telescopic arm mechanism and used for connecting the hand clamping mechanism with the telescopic arm mechanism and achieving rotation movement of the hand clamping mechanism. The hydraulically-driven mechanical hand can achieve space movement of five freedom degrees, overcomes the defects of an existing mechanical hand, is simple in structure, has the performance of controllability, adjustability, excellent performance, output flexibility and the like, can conduct operation under more environments instead of manual work, and improves the work efficiency.

Description

technical field [0001] The invention relates to the technical field of handling manipulators, in particular to a multi-degree-of-freedom hydraulically driven manipulator for workshop handling. Background technique [0002] In the traditional manufacturing field, industrial robots have become indispensable core automation equipment after their birth, growth, and maturity. At present, there are nearly one million industrial robots working in various production sites in the world. In the field of non-manufacturing, the application of robot technology has expanded to many fields of social and economic development, ranging from space capsules, spacecraft, and lunar exploration, to extreme environment operations, medical operations, and daily life services. The continuous progress of science and technology promotes the continuous development and improvement of robot technology; the development and wide application of robot technology promotes the improvement of people's lives, pro...

AI Technical Summary

Problems solved by technology

[0005] The degree of freedom that most existing manipulators can achieve is usually relatively limited, and the grasping force and stability of the manipulator are poor, which leads to the fact that these manipulators can adapt to less working environments and cannot carry out handling work under some complex working conditions
