Abstract

The invention discloses a seven-degree-of-freedom force feedback hydraulic driving mechanical arm which comprises a hydraulic control assembly, and six connecting rod assemblies, namely, a first connecting rod assembly, a second connecting rod assembly, a third connecting rod assembly, a fourth connecting rod assembly, a fifth connecting rod assembly and a sixth connecting rod assembly which are connected through rotary joints sequentially; each rotary joint is connected with a hydraulic oil cylinder; an encoder is arranged on each rotary joint; a force sensor is arranged at the front end of the fifth connecting rod assembly; a two-finger gripper is arranged at the front end of the sixth connecting rod assembly; fingers of the two-finger gripper are connected with a clamping claw oil cylinder through a connecting rod mechanism; and an oil way of each hydraulic oil cylinder is connected with the hydraulic control assembly. The seven-degree-of-freedom force feedback hydraulic driving mechanical arm adopts a full series connection structural form, has six rotational degrees of freedom, adopts hydraulic driving, and is high in load / self-weight ratio, high in level of protection, largein working space and attractive in appearance, and the application scope is broadened due to the characteristics.

Description

technical field [0001] The invention relates to a multi-joint hydraulically driven mechanical arm, which belongs to the technical field of mechanical arms. Background technique [0002] With the rapid development of industry, industrial robots, especially mechanical arms, have been widely used in assembly, welding, handling and other industries, which has greatly improved the automation level of industrial production and liberated humans from repetitive labor or extremely harsh working environments. come out. [0003] At present, almost all industrial robots are driven by servo motors and RV or harmonic reducers. Although they have high position accuracy and mature technology, their load / weight ratio is small and their environmental adaptability is poor, such as underwater, humidity, nuclear radiation or the presence of Environment with strong electromagnetic interference. [0004] Chinese patent document CN1035380701A discloses a 5-DOF hydraulic servo manipulator, which u...
