Automatic clamping mechanical hand with buffer damping function

Abstract

The invention discloses an automatic clamping mechanical hand with a buffer damping function and mainly relates to the technical field of mechanical hands. The automatic clamping mechanical hand comprises a machine body, a first joint shaft, a second joint shaft, a buffer mechanism and a clamping finger. The two ends of the first joint shaft are in matched connection with the machine body and the second joint shaft correspondingly. The first joint shaft, the second joint shaft and the clamping finger are all driven by a servo motor arranged in the machine body. The upper end of a piston rod is in matched connection with an air cylinder through the buffer mechanism, the lower portion of the piston rod penetrates through the second joint shaft and is embedded in a connection pipe in a sleeved mode, and the bottom of the piston rod is fixedly connected with a coupling. The clamping finger is in matched connection with the piston rod through the coupling, and V-shaped blocks are fixedly connected to the inner sides of the two ends of the clamping finger. The machine body is connected with an external controller. According to the automatic clamping mechanical hand with the buffer damping function, the damage to a workpiece is small, a worker can operate the mechanical hand easily, and the joint shafts can be precisely and stably operated for a long time; and moreover, the mechanical hand is small in redundant structure, very convenient to assemble, disassemble and maintain and low in manufacturing and operating cost.

Description

technical field [0001] The invention relates to the technical field of manipulators, in particular to an automatic clamping manipulator with the function of buffering and shock absorption. Background technique [0002] A manipulator is an automatic operating device that can imitate certain movement functions of the human arm to grab, carry objects or operate tools according to a fixed program. The manipulator is the earliest industrial robot and the first modern robot. It can replace the heavy labor of people to realize the mechanization and automation of production, and can operate in harmful environments, so it is widely used in machinery manufacturing, metallurgy, electronics, light sectors such as industrial and atomic energy. Among them, the clamping manipulator generates power through electric or pneumatic means to replace frequent manual grabbing actions, which reduces the work intensity of personnel to a certain extent. [0003] In recent years, with the continuous...

AI Technical Summary

Problems solved by technology

[0004] 1. The operation of the staff is complicated, and the position deviation of each joint axis often occurs during the operation;

[0005] 2. The axial impact force generated when the piston rod goes down can easily damage the workpiece;

[0006] 3. The manipulator has many redundant structures, large size and weight, high load requirements, cumbersome maintenance, and high manufacturing and operating costs
