Abstract
Description
Technical Field
[0001] This utility model relates to the field of welding robot technology, and in particular to an automatic welding robot for stainless steel pipes. Background Technology
[0002] Stainless steel pipe is a hollow, long, round steel material, widely used in industrial pipelines for petroleum, chemical, medical, food, light industry, and machinery, as well as mechanical structural components. It is also commonly used in furniture and kitchenware. Stainless steel pipe has a wide range of applications in various fields, and welding is often required during the processing of stainless steel pipe products.
[0003] Most existing welding operations are done manually. When welding, workers need to align the two sections of steel pipes first and then weld evenly around the joint. During welding, workers need to constantly adjust the direction and angle according to the welding position. When performing manual welding for a long time, not only is the workload high, but the quality of work is also difficult to guarantee. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic stainless steel pipe welding robot.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An automatic stainless steel pipe welding robot includes a welding table. A fixed arm is fixedly installed at the middle of the side wall of the welding table. A telescopic rod is fixedly installed on the bottom side of the fixed arm. A welding device is fixedly installed at the telescopic end of the telescopic rod. A controller is fixedly installed on the side wall of the welding table. A welding groove is opened on the top of the welding table. Control rings are arranged in the welding groove corresponding to the two sides of the fixed arm. An inner ring is arranged in the middle of the control ring. Fixed rods are fixedly installed at the upper and lower ends of the inner ring. The other end of the fixed rod is fixedly connected to the control ring.

[0023] In this embodiment, a fixing groove 13 is provided on the welding table 1 at the position corresponding to the control ring 8. A gear 14 is provided in the fixing groove 13. A toothed groove 15 is provided on the outer side of the control ring 8. The gear 14 meshes with the toothed groove 15. A rotating rod 11 is movably installed on the welding table 1 at the position corresponding to the gear 14. The rotating rod 11 connects the gears 14 together. A servo motor 10 is fixedly installed on the right end of the welding table 1 at the position corresponding to the rotating rod 11. A transmission belt 12 is movably installed on the output end of the servo motor 10. The other end of the transmission belt 12 is movably connected to the rotating rod 11. The servo motor 10 is started by the controller 9. The servo motor 10 can drive the rotating rod 11 to rotate. The rotating rod 11 can control the gear 14 to rotate. Since the gear 14 meshes with the toothed groove 15 on the outer side of the control ring 8, the gear 14 can drive the control ring 8 to rotate, thereby driving the steel pipe in the inner ring 19 to rotate.
[0024] In this embodiment, a threaded rod 18 is provided on the outer side of the inner ring 19, and the threaded rod 18 is threadedly connected to the inner ring 19. A fixing block 21 is provided on the inner side of the inner ring 19 corresponding to the position of the threaded rod 18. The back of the fixing block 21 is movably connected to the threaded rod 18. Rotating the threaded rod 18 controls the fixing block 21 to move closer to the side wall of the steel pipe. The fixing block 21 will clamp and fix the steel pipe in the middle position of the inner ring 19.
[0025] In this embodiment, movable grooves 6 are provided on both sides of the welding groove 22. A support frame 7 is movably installed in the movable groove 6. By adjusting the position of the support frame 7 in the movable groove 6, the tail end of the steel pipe can be supported to prevent the steel pipe from shifting position when rotating.
[0026] In this embodiment, a limiting block 16 is fixedly installed on the side wall of the welding groove 22 at the position corresponding to the control ring 8. A protrusion is provided on the inner side of the limiting block 16, and a limiting groove 17 is opened on the side wall of the control ring 8. The protrusion on the limiting block 16 can be movably engaged in the limiting groove 17. The control ring 8 can be movably installed on the welding table 1 through the limiting block 16.
[0027] In this embodiment, a drive motor 5 is fixedly installed on the top of the fixed arm 2. The output end of the drive motor 5 is fixedly connected to the telescopic rod 3. The controller 9 starts the drive motor 5 to drive the telescopic rod 3 to work, and controls the telescopic end of the telescopic rod 3 to drive the welding device 4 to move down, so that the welding end of the welding device 4 moves above the connection of the steel pipe.
[0028] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: When in use, the two steel pipes to be welded are placed in the inner rings 19 on both sides respectively, the welding point of the steel pipe is moved to the bottom of the welding device 4, and then the threaded rod 18 is rotated to control the fixing block 21 to move closer to the side wall of the steel pipe. The fixing block 21 will clamp and fix the steel pipe in the middle position of the inner ring 19. By adjusting the position of the support frame 7 in the movable groove 6, the tail of the steel pipe can be supported to prevent the position from shifting when the steel pipe rotates. Then, the controller 9 starts the drive motor 5 to drive the telescopic rod 3 to work, and controls the telescopic end of the telescopic rod 3 to drive the welding device 4 to move down, so that the welding end of the welding device 4 moves above the connection point of the steel pipe.
[0029] Subsequently, the servo motor 10 is started by the controller 9. The servo motor 10 drives the rotating rod 11 to rotate, which in turn controls the gear 14 to rotate. Since the gear 14 meshes with the tooth groove 15 on the outer side of the control ring 8, the gear 14 drives the control ring 8 to rotate, which in turn drives the steel pipe in the inner ring 19 to rotate. Then, the welding device 4 is started by the controller 9 to start working. The welding device 4 can then weld around the lower steel pipe, thereby automatically welding the two sections of steel pipe without requiring workers to manually weld for a long time, thus reducing the workload of workers.
