Description

Technical Field

[0001] This invention belongs to the field of aircraft component processing technology, specifically relating to a general-purpose large-size fuselage component flipping device and its implementation method. Background Technology

[0002] During CNC machining of machine body components, due to the large size and structure of the components, CNC machining centers cannot complete the machining of the back and belly of the machine in one operation. Tilting equipment is needed to assist in flipping the back and belly of the machine. Currently, the tilting method used in manufacturing has a low degree of automation, is prone to product tipping during tilting, and lacks position control, status monitoring devices, and safety alarms. Furthermore, due to the structural irregularities of different products and varying holding methods, the tilting equipment has a low degree of standardization; when there are many types of components, multiple tilting machines are required. In addition, in current production sites, component tilting and cleaning are performed at different workstations, occupying too many workstations, resulting in low automation, long time cycles, and high water costs during cleaning.

[0020] A method for implementing a general-purpose large-size body component flipping device: After the body component is transferred from the machining station to the flipping station by an AGV, the operator lowers the flipping frame assembly via control software. Once the body component has descended to a designated height according to its size, the lifting transmission system locks in place. The operator selects the required body component holding assembly based on the component type, moves it to the operating position and locks it, and moves the remaining holding assemblies to a safe position and locks them. The operator then disconnects the body component from the AGV and connects the body component to the holding assembly. After holding, the operator drives the flipping frame assembly to the designated height and locks it. The AGV then leaves the flipping area, the rotary transmission system starts working, and the flipping frame assembly begins to flip. Simultaneously, the encoder collects real-time data on the angles of the flipping shafts on both sides, providing real-time closed-loop feedback control for the flipping transmission system. After the flipping frame assembly reaches its final position, the rotary transmission system locks, awaiting the AGV to re-enter the flipping station. After the GV vehicle arrives, the lifting transmission system starts working again, the tilting frame assembly descends, and after descending to the designated height, the lifting transmission system locks. The operator enters the site, disconnects the connection between the body component and the body component holding assembly, and locks the body component holding assembly to a safe position. The body component is then reconnected and fixed to the AGV vehicle. After the operation is completed, the tilting frame assembly is raised again to the designated height, and the AGV vehicle transports the tilted body component away from the workstation. When the body component requires cleaning, the tilting process adopts a 360° continuous tilting method. During the tilting process, the control cabinet starts the automatic spray head, which automatically sprays and washes the body component 360°. At the same time, the circulating water treatment system starts working to recycle and treat the wastewater generated during the cleaning process. After the automatic rinsing is completed, the operator enters the site, switches between the automatic spray head and the manual spray gun, the control cabinet starts the pure water cleaning solenoid valve, and the operator performs manual pure water replenishment rinsing. After replenishment rinsing is completed, the control cabinet starts the high-pressure air gun solenoid valve to dry the components.

[0021] The beneficial effects of this technical solution are as follows:

[0023] II. This invention provides a universal large-size fuselage component tilting device that combines the tilting and cleaning stations.

After the flipping frame assembly 1 reaches its final flipped position, the rotary transmission system locks, awaiting the AGV to re-enter the flipping station. After the AGV arrives, the lifting transmission system starts working again, and the tilting frame assembly 1 descends. After descending to the designated height, the lifting transmission system locks, and the operator enters the site to disconnect the connection between the body component and the body component holding assembly 2.

At the same time, the circulating water treatment system starts working to recycle and treat the wastewater generated during the cleaning process. After the automatic rinsing is completed, the operator enters the site, switches between the automatic spray head 8 and the manual spray gun, and the control cabinet 6 starts the pure water cleaning solenoid valve. The operator performs manual pure water replenishment rinsing. After replenishment rinsing is completed, the control cabinet 6 starts the high-pressure air gun solenoid valve to dry the components.

7. A method for implementing a general-purpose large-size fuselage component flipping device, characterized in that: Using the general-purpose large-size body component flipping device as described in any one of claims 1-6, after the body component is transferred from the machining station to the flipping station by the AGV vehicle, the operator operates the flipping frame assembly (1) to descend through the control software. After descending to the specified height according to the size of the body component, the lifting transmission system is locked in place. The operator selects the required body component holding assembly (2) according to the type of body component, moves the selected body component holding assembly (2) to the operating position and locks it, and moves the remaining body component holding assemblies (2) to the safe position and locks them. The operator disconnects the body component from the AGV vehicle and connects the body component to the body holding assembly. After the holding is completed, the operator drives the flipping frame assembly (1) to rise to the specified height and locks it. The AGV vehicle drives out of the flipping area, the rotary transmission system starts working, the flipping frame assembly (1) starts to flip, and at the same time the encoder collects the angle data of the flipping shafts on both sides in real time, and performs real-time closed-loop feedback control on the flipping transmission system. After the flipping frame assembly (1) flips to the position, the rotary transmission system locks, waiting for the AGV vehicle to enter the flipping station again. After the vehicle arrives, the lifting transmission system starts working again. The tilting frame assembly (1) descends. After descending to the designated height, the lifting transmission system locks. The operator enters the site, disconnects the connection between the body component and the body component holding assembly (2), and locks the body component holding assembly (2) to a safe position. The body component is then reconnected and fixed to the AGV vehicle. After the operation is completed, the tilting frame assembly (1) is raised again. After reaching the designated height, the AGV... The machine body parts that have been flipped and transported by the vehicle leave the work station. When the machine body parts have cleaning requirements, the flipping process adopts a 360° continuous flipping method. During the flipping process, the control cabinet (6) starts the automatic spray head (8). The automatic spray head (8) automatically sprays and washes the machine body parts in 360°. At the same time, the circulating water treatment system starts to work and recycles the wastewater generated during the cleaning process. After the automatic rinsing is completed, the operator enters the site, switches the automatic spray head (8) and the manual spray gun, the control cabinet (6) starts the pure water cleaning solenoid valve, and the operator performs manual pure water replenishment. After the replenishment is completed, the control cabinet (6) starts the high-pressure air gun solenoid valve to dry the parts.
