Heavy type part spraying device

Abstract

The invention provides a heavy type part spraying device. The heavy type part spraying device comprises a six-axis joint robot and a spraying gun (1), a pressure adjusting device is arranged on the spraying gun (1) and comprises a shell installed on the spraying gun (1), turbine blades (3) installed in the shell and capable of rotating relative to the shell and a motor connected with the turbine blades (3), and a paint channel used for conveying paint is arranged inside the spraying gun (1); the lower portions of the turbine blades (3) are located in the paint channel inside the spraying gun (1); a control system connected with the six-axis joint robot and used for controlling motion of the six-axis joint robot is connected to the motor; and a mixing device is connected to an inlet of the paint channel of the spraying gun (1). By means of the heavy type part spraying device, the rotating speed of the variable frequency motor (2) can be set according to the height of the tail end of the six-axis joint robot at present, the aim of adjusting the pressure of the paint in the spraying gun (1) according to the height is achieved, and the conditions of insufficient spraying and excessive spraying are avoided.

Description

technical field [0001] The invention relates to a spraying device for heavy parts, belonging to the field of spraying equipment. Background technique [0002] Heavy-duty parts are large in size and high in height, and the height span of the spray gun during spraying is relatively large. Since the pressure of the liquid is more sensitive to the height, it is easy to have insufficient paint pressure and insufficient spraying at higher positions, and insufficient paint at lower positions. Overpressured, oversprayed conditions. [0003] In the prior art, no special spraying device is provided for heavy-duty parts to avoid under-spraying and over-spraying. Contents of the invention [0004] The purpose of the present invention is to provide a special spraying device for spraying heavy parts, so as to avoid insufficient spraying and excessive spraying. [0005] Technical scheme of the present invention is as follows: [0006] A heavy-duty parts spraying device, including a si...
