Abstract

The invention discloses a two-degree-of-freedom underwater manipulator. The two-degree-of-freedom underwater manipulator comprises a clamping joint and a rotating joint. The clamping joint comprises aclaw, a claw bracket, a lead screw and a first motor cover. The claw is fastened on the claw bracket by screws, and the claw and a sliding nut are connected by the screws, the sliding nut is installed on the lead screw, a first brushless direct-current motor and a first driving plate are arranged in the first motor cover, the output end of the first brushless direct-current motor is fixed to thelead screw, a sealing movable sleeve is connected to the lead screw through a set screw, a first sealing static sleeve seat is installed on the inner wall of the claw bracket, and a connection flangeis installed at the end, away from the claw, of the first motor cover. According to the two-degree-of-freedom underwater manipulator, the functions of clamping and rotating two-degree-of-freedom of the underwater manipulator are achieved, the structure is compact, the operation is flexible, and the reliability is high; and a complete waterproof design is adopted in the whole machine, and the requirements of long-term underwater work can be met.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a two-degree-of-freedom underwater manipulator. Background technique [0002] At present, underwater robots can be used not only for observation, but also for underwater operations. They are mainly used in rivers, lakes and seas for underwater observation, search and rescue, fishery resource development, marine mineral exploration and other fields. In many cases, underwater robots are required. to complete underwater tasks. At present, there are relatively few underwater manipulators, and the degrees of freedom and functions are single, and often only have one function of gripping. Contents of the invention [0003] The object of the present invention is to provide a two-degree-of-freedom underwater manipulator to solve the problem that the underwater manipulators in the prior art are relatively few, have a single degree of freedom and a single function, and often only have one...
