Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.
[0023] Embodiment 1, as Figures 1 - 3 shown, the present utility model provides a manipulator telescopic device for a welding robot used in manufacturing a motorhome trailer, including a manipulator arm body 1. A hole 1 is provided on the outer surface of the manipulator arm body 1. A rotating rod 1 is movably inserted into the inner surface of the hole 1. A movable block 4 is fixedly sleeved on the outer surface of the rotating rod 1. A driving motor 1 is arranged on one side of the outer wall of the rotating rod 1. A protective shell 6 is arranged on the outer surface of the driving motor 1. A square groove 7 is provided on the top of the movable block 4. A hydraulic cylinder 8 is arranged on the top of the square groove 7. A piston rod 9 is arranged at the output end of the hydraulic cylinder 8. A connecting plate 10 is fixedly installed on one side of the outer wall of the piston rod 9. A chute 11 is provided on one side of the outer wall of the movable block 4. A slide block 12 is movably embedded in the inner surface of the chute 11, and one side of the outer wall of the slide block 12 is fixedly connected to one side of the outer wall of the connecting plate 10. A fuel tank 13 is fixedly installed on one side of the outer wall of the movable block 4. A hole 2 is provided on the top of the fuel tank 13. A sealing cover 15 is movably inserted into the inner surface of the hole 2. A pipeline 16 is fixedly communicated with the top of the fuel tank 13. A water pump 17 is arranged on the outer surface of the pipeline 16. A nozzle 18 is arranged at the output end of the pipeline 16. A fixed ring 19 is fixedly sleeved on the outer surface of the pipeline 16, and one side of the outer wall of the fixed ring 19 is fixedly connected to one side of the outer wall of the movable block 4.
[0024] The effect achieved by the entire Embodiment 1 is as follows. First, the operation of the hydraulic cylinder 8 drives the piston rod 9 to extend and retract, ultimately driving the device to perform telescopic adjustment. At the same time, the slider 12 and the chute 11 cooperate with each other to assist during the extension and retraction of the piston rod 9, making it more stable during telescoping. Moreover, the operation of the first driving motor 5 can drive the first rotating rod 3 to rotate, thereby driving the movable block 4 to rotate for angle adjustment of the device. Meanwhile, the operation of the water pump 17 can extract lubricating oil from the oil tank 13, spray it out from the nozzle 18 through the pipeline 16, and spray the piston rod 9, enabling precise lubrication at a fixed time and quantity, avoiding the possible omission or over-lubrication in manual lubrication, effectively reducing equipment failures caused by improper lubrication, and reducing the workload and cost of maintenance.
[0025] Embodiment 2, as Figures 1 - 4 shown, a baffle 20 is fixedly installed on one side of the outer wall of the movable block 4, a connecting frame 21 is fixedly installed on one side of the outer wall of the connecting plate 10, a third hole 22 is formed on the outer surface of the connecting frame 21, a second rotating rod 23 is movably inserted into the inner surface of the third hole 22, a second driving motor 24 is arranged on one side of the outer wall of the second rotating rod 23, a connecting block 25 is fixedly sleeved on the outer surface of the second rotating rod 23, a welding head 26 is arranged at the bottom of the connecting block 25, a first infrared sensor 27 is arranged on one side of the outer wall of the connecting block 25, and a second infrared sensor 28 is arranged on one side of the outer wall of the connecting frame 21.
[0026] The effect achieved by the entire Embodiment 2 is as follows. When the device is in normal use, the operation of the second driving motor 24 can drive the second rotating rod 23 to rotate, and ultimately drive the connecting block 25 to rotate to adjust the angle of the welding head 26, making the device operate more flexibly. At the same time, the first infrared sensor 27 and the second infrared sensor 28 operate simultaneously, capable of real-time monitoring of the distance change between the manipulator and surrounding objects. If one of the sensors fails or is interfered with, the other sensor can still provide certain distance information, increasing the reliability and stability of the system. Meanwhile, the real-time feedback information helps the control system make a quick response, making the movement of the manipulator more stable and accurate.
[0027] Among them, the first driving motor 5, the hydraulic cylinder 8, the water pump 17, the second driving motor 24, the first infrared sensor 27, and the second infrared sensor 28 are all prior arts, and their components and operating principles are all publicly known technologies, and no further explanation will be given here.
[0028] Working principle: First, when the device is in normal use, a movable block 4 is fixedly sleeved on the outer surface wall of the first rotating rod 3. A first driving motor 5 is arranged on one side of the outer wall of the first rotating rod 3. When the first driving motor 5 operates, it can drive the first rotating rod 3 to rotate, thereby driving the movable block 4 to rotate for angle adjustment. Secondly, a hydraulic cylinder 8 is arranged at the top of the square groove 7. A piston rod 9 is arranged at the output end of the hydraulic cylinder 8. The piston rod 9 is fixedly connected to the connecting plate 10. At the same time, a chute 11 is opened on one side of the outer wall of the movable block 4. A slider 12 is movably embedded in the inner surface wall of the chute 11. And one side of the outer wall of the slider 12 is fixedly connected to one side of the outer wall of the connecting plate 10. When the hydraulic cylinder 8 operates, it can drive the piston rod 9 to expand and contract, thereby driving the connecting plate 10 to move. At the same time, the cooperation between the slider 12 and the chute 11 can assist the piston rod 9 to move, making the device more stable during telescoping and improving the welding quality. Secondly, a pipeline 16 is fixedly communicated with the top of the fuel tank 13. A water pump 17 is arranged on the outer surface wall of the pipeline 16. A spray head 18 is arranged at the output end of the pipeline 16. When the water pump 17 operates, it can extract the lubricating oil in the fuel tank 13, pass through the pipeline 16, and finally spray it onto the piston rod 9 through the spray head 18, which can reduce the wear degree of components, extend the service life of the telescopic device of the manipulator, and the spray head 18 sprays in a spray shape. The spray-shaped lubricating oil particles are smaller and can penetrate into the surface and interior of the parts more quickly, providing immediate lubrication protection. Secondly, a fixing ring 19 is fixedly sleeved on the outer surface wall of the pipeline 16. And one side of the outer wall of the fixing ring 19 is fixedly connected to one side of the outer wall of the movable block 4. The fixing ring 19 can ensure the stability of the pipeline 16. Secondly, a second driving motor 24 is arranged on one side of the outer wall of the second rotating rod 23. A connecting block 25 is fixedly sleeved on the outer surface wall of the second rotating rod 23. When the second driving motor 24 operates, it can also drive the second rotating rod 23 to rotate, thereby driving the connecting block 25 to rotate, and finally also adjusting the angle of the device. At the same time, an infrared sensor 1 27 is arranged on one side of the outer wall of the connecting block 25, and an infrared sensor 2 28 is arranged on one side of the outer wall of the connecting frame 21. The two sensors can cover a wider area and reduce the detection blind area, which is particularly important for some welding workpieces with irregular shapes or large sizes, ensuring that the manipulator can comprehensively sense the surrounding environment during telescoping.
[0029] The above are only the preferred embodiments of the present invention, and are not limitations on the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
