Mechanical arm of robot

Abstract

The invention discloses a mechanical arm of a robot. The mechanical arm comprises a driving barrel, wherein two parallel connection blocks are arranged at the left end of the driving barrel, and connection holes are formed in the connection blocks, so that fixing of the left end of the barrel is facilitated; a touch handle is arranged at the right end of the driving barrel; the touch handle is made of a rubber material; the right end part of the touch handle is a contracted tip end; the section of the touch handle is rectangular; a negative pressure cavity is formed inside the touch handle; and a plurality of contraction slots are formed in the upper surface of the touch handle in an equal spacing manner. The mechanical arm is simple and reasonable in structure; the inside of the touch handle made of flexible plastic is hollowed, and then the tensile strengths of the upper and lower surfaces of the touch handle are set to be different, so that the touch handle can be bent in different extents by adjusting air pressure inside the touch handle; and therefore, a cup can be conveniently held. The mechanical arm of the robot is simpler in structure, thus contributing to reducing the cost; furthermore, the touch handle is made of a plastic material, thus facilitating injection molding; and the mechanical arm is high in machining efficiency and high in practicability, and the production efficiency of the device can be improved favorably.

Description

technical field [0001] The invention relates to the technical field of mechanical arms, in particular to a robotic mechanical 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 mission is to assist or replace human work in jobs such as manufacturing, construction, or hazardous jobs. [0003] That is, the robot body, the arm of which generally adopts a space open-chain linkage mechanism, in which the kinematic pair (revolving pair or moving pair) is often called a joint, and the number of joints is usually the number of degrees of freedom of the robot. According to different joint configuration types and motion coordinate forms, robot actuators can be divided into rectangular coordinates, cylindrical coordinates, polar coordinates and joint coordinates. For anthropomorphic considerati...

Problems solved by technology

[0004] Different solutions are required for different environments. Robots used in the service industry need to hold cups. The existing robotic arms are applied from other industries. Although the problem of holding cups can be realized, this kind of machinery The arm is relatively expensive and is not suitable for use in the service industry. To solve the above problems, an octopus tentacle-type mechanical arm is first provided
