Precise clamping rotary hydraulic manipulator

Abstract

The invention discloses a precise clamping rotary hydraulic manipulator. The precise clamping rotary hydraulic manipulator comprises a bearing base, a mechanical arm and a clamping manipulator; a rotating table is mounted at the top of the bearing base; the rotating table comprises a rotating motor, and a rotating disc in transmission connection with the rotating motor; a first hydraulic cylinderis mounted at the top of the rotating table; the mechanical arm is mounted at the top of the first hydraulic cylinder; a second hydraulic cylinder is fixedly mounted at one end of the mechanical arm;and a driving motor is mounted at an output end of the second hydraulic cylinder. The precise clamping rotary hydraulic manipulator can realize the rotation and extension adjustment to flexibly move to an object to be clamped so as to effectively improve the manipulator clamping precision; and through arrangement of a negative-pressure cavity and a negative-pressure sucker on a mechanical jaw, a negative-pressure absorption fixing principle is used for achieving firmer and more stable object clamping by the mechanical jaw, so that the clamping damage degree of the object is reduced, and the practicability is higher.

Description

technical field [0001] The invention relates to a manipulator, in particular to a precision clamping rotary hydraulic manipulator, which belongs to the technical field of manipulator equipment. Background technique [0002] With the continuous development of science and technology and the continuous improvement of the level of automation, the manipulator is an automatic operating device that can imitate certain action functions of the human hand and arm to grab, carry objects or operate tools according to a fixed program. Various expected operations are completed through programming, and the structure and performance have both the advantages of man and manipulator. However, the existing manipulator has low flexibility of movement and adjustment when gripping objects, which affects its gripping accuracy; And when the object is picked up, due to the gravity of the object itself, the object needs a large clamping force, which is easy to cause damage to the object, and affects t...
