Spraying robot mechanical arm with five freedom degrees

Abstract

The invention provides a spraying robot mechanical arm with five freedom degrees. A base box is included, and an upper end port of the base box is closed for covering through a box cover bearing pedestal; a rotating disk is rotationally supported on the middle portion of the box cover bearing pedestal; the base box is provided with a driving motor and a speed reducer; the output end of the drivingmotor is connected with the input end of the speed reducer; the output end of the speed reducer is connected with the rotating disk; a lower arm joint is vertically fixed to the upper end face of therotating disk; the upper end of the lower arm joint is hinged to the lower end of a middle arm joint; an upper arm joint used for installing a spraying device is hinged to the upper end of the middlearm joint; a first hydraulic cylinder is hinged to one side of the lower portion of the lower arm joint; the top end of a piston rod of the first hydraulic cylinder is hinged to one side of the middle portion of the middle arm joint; a second hydraulic cylinder is hinged to the other side of the middle portion of the middle arm joint; and the top end of a piston rod of the second hydraulic cylinder is hinged to the upper arm joint. According to the spraying robot mechanical arm with the five freedom degrees, the rotating disk is driven by a stepping motor, in combination with large-angle rotating formed by the structures of the upper, middle and lower three arm joints, the rotating freedom degree of the mechanical arm is improved, rotating of the spraying robot mechanical arm in all directions is flexible, using is flexible and convenient, and the automation degree is high.

Description

technical field [0001] The invention belongs to the technical field of robots, and in particular relates to a mechanical arm of a spraying robot with five degrees of freedom. Background technique [0002] With the development of society, people's living standards continue to improve, and various new products come one after another, entering people's work and life. Industrial robot is a kind of automation equipment with high degree of automation and work efficiency. Robot is now widely used in various fields, and it can be seen in various fields. With the continuous development of industrialized society, the demand for robots is also increasing, and the same is true for the spraying processing industry. Now there are various spraying robots and mechanical arms on the market, and the shape samples are different, but the existing spraying There are some shortcomings in the use of the robotic arm of the robot. For example, the arm does not have the function of moving up, down, ...

With the continuous development of industrialized society, the demand for robots is also increasing, and the same is true for the spraying processing industry. Now there are various spraying robots and mechanical arms on the market, and the shape samples are different, but the existing spraying There are some shortcomings in the use of the robot arm. For example, the arm is not equipped with the function of moving up, down, left, and right, and the robot cannot rotate. The existing spraying robot is fixed at a single point and the spraying method is fixed, which is very inconvenient to use.
