Arm stretching and bending mechanism for industrial robot

Abstract

The invention discloses an arm stretching and bending mechanism for an industrial robot, and belongs to the technical field of robot arms. The arm stretching and bending mechanism for the industrial robot comprises a base. A workbench is connected to the top of the base. A fixing plate is connected to the top of the workbench. A conveying rack is slidably connected to the outer wall of the workbench. A first gear is connected to the outer wall of the conveying rack in an engaged mode. A first connecting rod is connected to the outer wall of the first gear. Second connecting rods are rotatablyconnected to the two ends of the first connecting rod. A third connecting rod is connected to the end, away from the first connecting rod, of each second connecting rod. A second gear is connected tothe joint of each third connecting rod and the corresponding second connecting rod. A third gear is connected to the outer wall of each second gear in an engaged mode. A fourth connecting rod is connected to the outer wall of each third gear. Fifth connecting rods are connected to the two ends of the fourth connecting rods. Sixth connecting rods are connected to the ends, away from the fourth connecting rods, of the two fifth connecting rods. Clamping mechanisms are connected to the outer walls of the sixth connecting rods. According to the arm stretching and bending mechanism for the industrial robot, the flexibility of robot arms can be improved through the rotation of the connecting rods.

Description

technical field [0001] The invention relates to the technical field of robot arms, in particular to an extension and bending mechanism of an industrial robot arm. Background technique [0002] The robot gripper is a device that can imitate the movement of the human hand and arm to grasp, carry objects or operate tools. It can effectively reduce the labor load of personnel and improve work efficiency. It has been widely used in machinery manufacturing, metallurgy, electronics, etc. And other fields, with the rapid development of modern industrial production, the industry has developed a variety of types of robot grippers, factories gradually replace manual production with robots, in the past, manual production was carried out by people holding production tools. The use needs to use the gripper to install the production tool and install it at the end of the robot. [0003] However, the connection between the forearm and the rear arm of the existing robot arm is relatively com...

Problems solved by technology

[0003] However, the connection between the forearm and the rear arm of the existing robot arm is relatively complicated, and the degree of freedom of rotation between the forearm and the rear arm is not high, which causes the robot gripper to be inflexible enough in the process of grabbing objects, making the gripping efficiency of the robot gripper Low, which wastes a lot of time and energy, which is not conducive to the increase of industrial production costs
