Abstract

The invention provides a manipulator based on a spherical screw pair. The manipulator comprises a spherical screw body, a rack mechanism, a rotary shaft, two clamping jaws, two clamping beams and two connection rods, wherein the spherical screw body is arranged in the rack mechanism; the rotary shaft is connected to the bottom of the spherical screw body; the rack mechanism is provided with an arc-shaped slide groove along the both sides of the spherical screw body respectively; two slide blocks are embedded in the corresponding slide grooves by convex keys; each of the slide blocks is slidably engaged with a spherical screw groove in the spherical screw body; each of the slide blocks is pivotedly connected with one end of the corresponding clamping beam through one connection rod; the other end of each of the clamping beams is linked with the corresponding clamping jaw through a spherical hinge; an elbow is arranged on each of the clamping beams; and each of the elbows is pivotedly connected to the rack mechanism. The manipulator provided by the invention is capable of realizing various special movement functions, and ensuring the accuracy and reliability of movements and safety and stability in component mechanics, thus realizing an operation for a target object.

Description

【Technical field】 [0001] The invention relates to a manipulator based on a spherical screw pair. 【Background technique】 [0002] Robot is a kind of high-tech automatic production equipment developed in recent decades, and manipulator is an important branch of robot. When the manipulator grabs the material, it usually simulates the grabbing action of the human hand. The outer surface of the material is clamped from the outside by the fingers of the manipulator and the palm of the manipulator, so as to realize the grasping and unloading of the material. At present, most manipulators or clamping mechanisms use hydraulic cylinders and motors to directly drive the movement of the jaws through a link mechanism. If the hydraulic cylinder and the motor fail, it is difficult to guarantee the safety performance of the jaws. 【Content of invention】 [0003] The technical problem to be solved by the present invention is to provide a manipulator based on a spherical screw pair, which ...
