Problems solved by technology

[0002] The robot gripper is a robot part that can realize the function similar to the human hand. The robot gripper is a part used to hold the workpiece or tool. It is one of the important actuators. According to the shape of the workpiece held by the robot, the gripper can be divided into Various types: mechanical grippers, magnetic chucks, welding guns and general-purpose grippers. The rotation angle of the grippers in the prior art is not enough, the opening and closing degree of the grippers is too small, it is not flexible to use, and it is easy to grasp loosely. When used at night , it is not easy to locate, and it cannot be rotated 360 degrees, and the grabbing object in a special position is not easy to grab

Abstract

The invention discloses a rotatable machine gripper. A first worm gear motor and a second worm gear motor are fixedly arranged on the front side and the rear side between an upper base plate and a lower base plate respectively; a finger portion comprises a left finger and a right finger which are respectively formed by two parallelly arranged rotatable L-shaped pushing rods; a polygonal iron piece is fixedly arranged at one end of every L-shaped pushing rod; a rotation portion comprises a second back plate; and a third worm gear motor which is fixedly arranged on the second back plate is connected with the back of a first back plate. The rotatable machine gripper has the advantages of achieving 360 degree rotation of the machine gripper and being convenient to grab workpieces due to the worm gear motors and enabling rotation and opening and closing control of the machine gripper to be flexible and an extensible range to be large due to the facts that an opening and closing angle of the machine gripper is 160 degrees and the opening and closing degree is large.

Description

technical field [0001] The invention relates to the technical field of robot grippers, in particular to a rotatable robot gripper. Background technique [0002] The robot gripper is a robot part that can realize the function similar to the human hand. The robot gripper is a part used to hold the workpiece or tool. It is one of the important actuators. According to the shape of the workpiece held by the robot, the gripper can be divided into Various types: mechanical grippers, magnetic chucks, welding guns and general-purpose grippers. The rotation angle of the grippers in the prior art is not enough, the opening and closing degree of the grippers is too small, it is not flexible to use, and it is easy to grasp loosely. When used at night , It is not easy to locate, and it cannot be rotated 360 degrees. It is not easy to grab objects in special positions. Contents of the invention [0003] The object of the present invention is to provide a reliable rotatable robotic g...
