Problems solved by technology

However, the traditional manipulator only has the rotation of the wrist to drive the claws to do 360° rotation, and lacks the 360° rotation of the wrist itself. Therefore, the output of the manipulator's working trajectory is not flexible, and it is difficult to complete some work tasks. The movement requirements of the manipulator

Abstract

The invention provides a wrist-claw double-rotation manipulator. The wrist-claw double-rotation manipulator is characterized by being composed of a horizontal rotating platform, a big arm, a verticalrotating platform, a convolute wrist and a claw. The horizontal rotating platform comprises a base, a first rotating table and a first motor. One end of the large arm is hinged to the first rotating table, the first rotating table is arranged on the base and can rotate horizontally, the first motor is connected with the first rotating table to drive the first rotating table to rotate, and a firsthydraulic cylinder is hinged to the position between the large arm and the first rotating table so as to drive the large arm to conduct lifting movement. The vertical rotating platform comprises a rotating seat, a second rotating table and a second motor. The rotating seat is hinged to the other end of the large arm, the second rotating table is arranged on the rotating seat and can rotate vertically, and the second motor is connected with the second rotating table so as to drive the second rotating table to rotate. The manipulator is flexible in track output, simple in structure and flexiblein action. A closed movement chain is formed, and the manipulator has the advantages of being high in rigidness and bearing capability, low in inertia and good in dynamic property.

Description

Technical field [0001] The invention relates to the field of robots, in particular to a double-rotating manipulator with wrist claws. Background technique [0002] Manipulators are widely used in welding, assembly, cutting, handling and other operations in industrial production. However, traditional manipulators only have the wrist rotation to drive the claws to make a 360° rotation movement, and lack the wrist to make a 360° rotation movement. Therefore, the output of the manipulator's work trajectory is not flexible and it is difficult to complete the movement requirements of the manipulator. Summary of the invention [0003] The purpose of the present invention is to provide a double-rotating manipulator with wrist claws, which has a large working space, flexible motion track output, adopts a closed kinematic chain structure, and is suitable for assembly and machining operations. [0004] In order to achieve the above objective, the present invention provides a wrist-claw double...
