Abstract

The invention discloses a cable parallel robot aircraft part spraying hose displacement device, and belongs to the technical field of aircraft part spraying equipment. The device mainly comprises a pi-shaped support frame, two stepping motors, two concave wheels, a cable parallel aluminum frame, a position sensor, a controller and an alarm. The spraying hose passes through the concave wheel, one end of the spraying oil drum is connected with the spraying oil drum, the other end is connected with a spray nozzle. The stepping motor is matched with the concave wheel to accurately control the dosage of the spraying hose, a position sensor on the aluminum-type framework connected in parallel through a cable detects the movement position of the spraying nozzle, and the displacement of the spraying hose is adjusted in real time through a controller according to a preset program instruction. When the spray head reaches a preset position, the position sensor signals the controller to drive the stepping motor and the concave wheel to act, and if abnormal movement is detected or exceeds a preset range, the position sensor triggers an alarm. The device solves the difficult problem of controlling the dosage of the hose in the spraying of the aircraft parts, improves the spraying accuracy and uniformity, and enhances the safety of the spraying process.
