Automatic spraying robot device

Abstract

The invention relates to an automatic spraying robot device in the field of automatic coating of an aircraft. The automatic spraying robot device comprises a movable spraying robot consisting of a three-vertical-coordinate-axis movable platform and a spraying execution mechanism, and a barrel supporting autorotation tool, wherein the three-vertical-coordinate-axis movable platform is connected with the spraying execution mechanism in a sliding manner and arranged on a slide rail at one side of a storage box, and the barrel supporting autorotation tool is connected with the storage box in a rotating manner. While the robot moves rapidly along a Y axis, a spray head can form any dihedral angle of 0 to 90 degrees with a YZ plane by adopting the Y axis as an intersection line, so that the spraying in the downward vertical direction, oblique upward direction and horizontal direction can be realized, and the automatic spraying robot device can be adaptive to storage boxes of different diameters and different work conditions, and the flexibility is very high, in addition, the automatic spraying robot can move to an arc end surface, an appropriate distance between the spray head and the arc end surface can be realized, and the vertical uniform automatic spraying can be realized in real time. The automatic spraying robot device is compact in layout, high in flexibility, simple in control way, high in spraying precision, uniform in coating thickness, small in environmental pollution, high in spraying efficiency and good in economic benefit.

Description

technical field [0001] The invention relates to a technology in the field of automatic painting of aircraft, in particular to a robot equipment for automatic spraying of heat-insulating coatings for rocket storage tanks. Background technique [0002] The spraying of thermal insulation coating is an important part in the manufacturing process of rocket structural parts. With the development of a new generation of rockets, the requirements for spraying quality of launch vehicles are increasing day by day. The quality of coating has a great impact on the reliability, economy and safety of launch vehicles. Sex matters. At present, the traditional manual spraying is still used in the domestic aerospace field. Due to the large size and complex structure of the tank, the accuracy of manual spraying is poor, and the thickness of the coating is difficult to control due to human factors, and it is easy to appear too thick; at the same time, with the high density of launch vehicles Wi...

Problems solved by technology

[0006] The present invention aims at the defects of the existing thermal insulation coating spraying method of the rocket storage tank, and proposes a robot equipment for automatic spraying. While the robot can realize rapid movement along the Y axis, the spray head can form a line of intersection with the YZ plane with the Y axis as the intersection line. Any dihedral angle of 0-90° can realize spraying at any angle vertically downward, obliquely upward and horizontally. It can adapt to tanks of different diameters and different working conditions, and has very high flexibility; in addition, automatic spraying The robot can also move to the arc end face to realize the real-time and appropriate distance between the nozzle and the arc end face for automatic spraying vertically and evenly
