Clamping and releasing mechanism for robot arm

Abstract

The invention discloses a clamping and releasing mechanism for a robot arm. Two clamping arms are mounted in sliding grooves through cross-rotation of a central axis lock nut, and the clamping arms are slidably mounted on a base through a waist-shaped hole structure. The jaws of the elastic block are set in a circular arc surface structure, and the elastic block is movably installed on the inside of the clamping arm through a buckle structure, and a spring hole is opened on the clamping arm, and the spring and the adjusting bolt are installed In the spring hole, and the two ends of the spring abut against the elastic block and the adjusting bolt respectively, the tension spring is connected between the clamping openings of the two clamping arms. By setting the elastic block, it is possible to avoid damage to the material of the round rod due to excessive clamping force, so the quality of the produced and processed products can be guaranteed, and the elastic force of the spring pressing the elastic block can be adjusted to meet the different needs of different products. The opening and closing of the clamping arm is controlled by the telescopic cylinder, which has the advantages of simple structure and low production cost.

Description

Technical field: [0001] The invention belongs to the technical field of automatic robots, and in particular relates to a clamping and releasing mechanism for a robot arm. Background technique: [0002] A robot is a machine device that performs work automatically. It can accept human command, run pre-programmed programs, and act according to principles formulated with artificial intelligence technology. Its task is to assist or replace the work of human work. As the key component of the robot, the mechanical arm has many functions and can meet the different needs of daily production and life. During the production, processing and feeding of some round rod materials, each round rod material needs to be loaded separately. Currently, it is used for round rod materials. The clamping mechanism of the mechanical arm for rod clamping is easy to damage the surface of the round rod material, and after repeated use, its opening and closing force will change, which will easily affect ...

As the key component of the robot, the mechanical arm has many functions and can meet the different needs of daily production and life. During the production, processing and feeding of some round rod materials, each round rod material needs to be loaded separately. Currently, it is used for round rod materials. The clamping mechanism of the mechanical arm clamped by the rod is easy to damage the surface of the round rod material, and after repeated use, its opening and closing force will change, which will easily affect the production and processing efficiency of the actual assembly line production
