Pipeline inner wall spraying robot

Abstract

The invention relates to a pipeline inner wall spraying robot which comprises a base, a stand column and a multi-section servo electric cylinder, wherein the stand column is vertically arranged on the base, and the multi-section servo electric cylinder is arranged on one side of the stand column. The stand column is vertically and fixedly connected to a sliding block A on a linear guide rail A. The middle portion of the side face, across the linear guide rail A, of the stand column is provided with a groove in the height direction of the stand column, and the upper end face of the groove is reserved. A Z-axis box is fixed to a sliding block B of a liner guide rail B on the stand column. The multi-section servo electric cylinder is installed in the Z-axis box in a penetrating mode. The multi-section servo electric cylinder comprises a servo motor, a synchronous wheel and a cylinder barrel structure. The cylinder barrel structure comprises a fixed ball screw, a ball screw nut, a hollow ball screw, a cylinder barrel body, an output shaft and a terminal output shaft. The pipeline inner wall spraying robot has the advantages that a four-axis linkage function is achieved, the speed is high, operation is stable, positioning is accurate, and the defects of spraying omission and repeated spraying are overcome.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a pipeline inner wall spraying robot. Background technique [0002] In the field of mechanical manufacturing technology, it is often necessary to spray the inner wall of the pipeline. At present, the inner wall of the pipeline is basically sprayed manually, which has low efficiency, harsh working environment and high labor intensity. Especially for special pipelines that require high-temperature spraying, because the sprayed powder contains fluorine and is highly toxic, it is extremely harmful to the human body. At the same time, due to manual spraying operations, there will be phenomena such as missed spraying and repeated spraying, which not only affects the quality but also wastes powder materials. Therefore, automatic spraying by robots is required. [0003] The Chinese patent application with the publication number CN 105750131 A "a spraying robot" includes a base, a column,...

AI Technical Summary

Problems solved by technology

Although the spraying robot can accurately control the distance of the nozzle and the thickness of the spraying during spraying, it does not have the function of 4-axis linkage, and the spraying method is also limited, and there will be disadvantages of missed spraying and repeated spraying
