Description

Technical Field

[0001] The invention relates to the technical field of paint spraying, touch-up and repair robots, and in particular to a paint spraying, touch-up and repair robot. Background Art

[0002] Rocket launch includes propulsion system, navigation and control, launch platform and mission planning. The propulsion system is mainly the rocket engine, which usually uses liquid fuel or solid fuel to provide the necessary thrust. The navigation and control system ensures that the rocket flies along the predetermined trajectory and makes necessary adjustments. The launch platform is the launch base of the rocket, which supports and guides the rocket to take off. Mission planning involves launch window selection, orbit calculation and mission execution strategy. The rocket guide slot is an important component in the rocket launch system. Its main function is to guide and manage the airflow ejected from the rocket engine nozzle. Its design and function play a vital role in the launch and flight of the rocket. The main function of the guide slot is to guide the jet airflow so that it flows in a predetermined direction, which helps to control the thrust direction and flight stability of the rocket. By optimizing the flow of airflow, the guide slot can reduce air resistance, thereby improving the overall performance and efficiency of the rocket. The guide slot design can effectively reduce the direct impact of high-temperature airflow on the rocket structure and protect the rocket material from overheating or mechanical damage. At present, the base of the flame jet during rocket launch, the high-temperature resistant material will be damaged and needs to be repaired by spraying paint, but because the environment after the rocket launch is not suitable for manual operation, a robot is needed to replace manual work to complete these tasks.

[0003] At present, the angle adjustment range of the paint head of traditional paint spraying and repainting repair robots is small and cannot be raised or lowered. The small angle adjustment range of the paint head will lead to incorrect spraying angle, resulting in uneven paint coating or missed paint. The inability to rise or fall will cause the paint head to be unable to reach different heights of the workpiece or have difficulty in processing surfaces of complex shapes, resulting in incomplete coating coverage, so improvements are needed.

[0034] Example 3: Reference Figure 6-7 As shown, two rotating rods 30 are symmetrically rotatably connected at the top of the paint tank 2, and multiple groups of stirring rods 31 are evenly and symmetrically fixedly installed on the outer wall of each rotating rod 30. The stirring rods 31 improve the stirring effect of the paint, and the top of the rotating rod 30 passes through the paint tank 2 and is fixedly installed with a pulley 32, and a belt 33 is installed between the two pulleys 32.

[0036] The use method and working principle of the device are as follows: when in use, first rotate the screw cap 4, and remove the screw cap 4 from the outer wall of the feed pipe 3 after rotating a certain number of times, and then add the paint from the feed pipe 3 into the paint tank 2, and then align the screw cap 4 with the feed pipe 3 after adding a certain amount, and then rotate the screw cap 4 after aligning, and after rotating a certain number of times, the screw cap 4 will be firmly fixed on the feed pipe 3. After adding the paint, start the drive motor 35, and when the drive motor 35 works, it will drive one of the pulleys 32 to rotate, and one of the pulleys 32 will make its belt 33 drive another pulley 32 to rotate during the rotation process, and the two pulleys 32 will drive the two rotating rods 30 to rotate inside the top of the paint tank 2 during the rotation process, and the two rotating rods 30 will drive the multiple groups of stirring rods 31 to rotate during the rotation process, and the multiple groups of stirring rods 31 will evenly stir the paint in the paint tank 2 during the rotation process, thereby effectively preventing the paint from solidifying during use, and improving the use effect of the paint. After uniform stirring, start the driving motor 28. When the driving motor 28 is working, it will drive the gear 29 to rotate. The gear 29 drives the chain 26 through the sprocket 25. The transmission of the chain 26 causes the other sprocket 25 to rotate. During the rotation, the two sprockets 25 will drive the two shafts 23 to rotate inside the four connecting plates 22. During the rotation, the two shafts 23 will drive the four moving wheels 24 to rotate, thereby pushing the device on the bottom plate 1 to move, thereby improving the driving efficiency of the moving wheels 24, ensuring the smooth movement of the device, and being able to adapt to different movement requirements and load conditions.When the device is moved to the position where paint needs to be sprayed, the drive motor 28 is turned off and the liquid pump 7 is started. When the liquid pump 7 is working, the paint in the paint tank 2 will be pumped from the first hose 8 to the second hose 9, and then the paint in the second hose 9 will be evenly sprayed out from the paint spray head 10. When the paint spray head 10 needs to be adjusted according to the height of the sprayed object, the drive motor 18 is started. When the drive motor 18 is working, it will drive the threaded rod 19 to rotate. During the rotation, the threaded rod 19 will drive the slider 20 to slide up or down inside the empty groove 17. During the upward or downward sliding process, the slider 20 will drive the fixing ring 21 to move up or down together. During the upward or downward movement, the fixing ring 21 will drive the paint spray head 10 to move up or down together, thereby improving the height adjustment effect of the paint spray head 10 and effectively avoiding The inability of the paint spray head 10 to reach different heights of the workpiece will result in incomplete coating coverage. When the spray angle needs to be adjusted, the telescopic cylinder 11 is started. When the telescopic cylinder 11 is working, it will drive the connecting rod 12 to move. The connecting rod 12 will drive the rack 13 to move together during the movement. The rack 13 will drive the gear 15 meshing with it to rotate during the movement. The gear 15 will drive the shaft 14 to rotate inside the bottom plate 1 during the rotation. At the same time, the gear 15 will also drive the frame 16 to rotate together. The frame 16 will drive the slider 20, the fixing ring 21 and the paint spray head 10 to rotate together during the rotation, thereby improving the angle adjustment effect of the paint spray head 10, effectively avoiding the incorrect spray angle caused by the inability to adjust the angle of the paint spray head 10 or the adjustment angle being too small. In the process of using the device, the hydraulic cylinder 37 can be started to drive the limit long plate 38 to move downward. When the limit long plate 38 moves a certain distance, it will resist the ground, thereby improving the limiting effect of the device, effectively avoiding the device being driven by the moving wheel 24 to shake during use.
