[0001] The utility model relates to the technical field of welding devices, and more specifically, the utility model relates to a self-rotating full-automatic welding device. Background Art

[0002] Welding is a manufacturing process and technology for joining metals or other thermoplastic materials by means of heating, high temperature or high pressure. The welding process can effectively utilize materials, and different materials with different properties can be used in different parts of the welded structure to give full play to the advantages of various materials.

[0003] Currently, in the construction field and the manufacturing field, it is often necessary to weld workpieces to ensure the strength and applicability of the workpieces. In order to reduce the workload, an automatic welding device is usually used for welding. When the device is performing welding operations, its welding method is to perform left and right spot welding on the welding parts placed on the workpiece to fix the welding parts, and then perform circumferential welding on the welding parts after fixation, so as to complete the welding operation.

[0004] Although this device can effectively reduce the workload, when welding the welding parts, the welding requirements between different workpieces are also different, which results in different welding intervals between the welding parts, and it is necessary to accurately position the welding parts. However, the current welding device takes time and effort to determine the position of the welding parts, and when positioning a relatively large welding part, the welding part is prone to deviation, so it needs to be improved and optimized.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] As Figures 1 to 6 shown, the present utility model provides a self-rotating full-automatic welding device, which includes a workbench 1. A guide rail 2 is fixedly installed on the top of the workbench 1. A moving table 3 is movably installed on the outer wall of the guide rail 2. A column 4 is fixedly installed on the top of the moving table 3. A lifting table 6 is movably installed on the right outer wall of the column 4. A welding mechanism 5 is fixedly installed on the left outer wall of the column 4. A steel pipe 7 is fixedly arranged on the top of the workbench 1. A welding part 8 is placed on the top of the steel pipe 7;

[0026] A fixed table 12 is fixedly installed at the front end of the lifting table 6. A rotary cylinder 13 is fixedly installed on the top of the fixed table 12. A rotating rod 14 is rotatably installed inside the fixed table 12. The output shaft of the rotary cylinder 13 is fixedly connected to the rotating rod 14. A pressing rod 15 is movably installed inside the rotating rod 14. The top of the pressing rod 15 and the inner wall of the rotating rod 14 are elastically connected by a first spring 16. A positioning block 17 is fixedly installed at the bottom of the pressing rod 15. Four groups of pressing plates 18 are arranged on the outer wall of the positioning block 17. And the four groups of pressing plates 18 are rotatably connected to the positioning block 17 through hinges 19. The pressing plates 18 and the positioning block 17 are elastically connected by a second spring 20 above.

[0027] When it is necessary to weld the iron pipe 7 and the welding part 8, the staff first fixes the iron pipe 7 just below the welding head 27 and rotates the screw 11. The rotation of the screw 11 drives the support platform 9 with which it is threadedly sleeved to move upward along the guide rod 10, further allowing the support platform 9 to support the iron pipe 7 to ensure the stability of the welding. At this time, after the staff places the welding part 8 at the position where welding is required, the column 4 is moved to the vertical position of the welding part 8, so that the positioning block 17 and the welding part 8 are aligned. Then the staff starts the cylinder on the top of the column 4 to move the lifting platform 6 downward. At this time, the positioning block 17 passes through the center position of the welding part 8 and conflicts with the outer wall of the iron pipe 7 to complete the positioning. When the positioning block 17 moves downward, the pressure rod 15 will squeeze the spring 16 upward, and through the elastic potential energy of the spring 16, the positioning block 17 is prevented from excessively squeezing the outer wall of the iron pipe 7, avoiding the positioning block 17 The positioning operation affects the quality of the outer wall of the iron pipe 7. At this time, the positioning block 17 passes through the center of the welding part 8, and the four groups of pressure plates 18 conflict with the inner wall of the welding part 8 through the elastic potential energy of the spring 20, avoiding the positioning deviation caused by the excessive hole of the welding part 8, so that the welding part 8 is always accurately fixed on the welding position of the iron pipe 7. At this time, the staff can turn the knob 26 to make the gear 2 25 drive the gear 1 24 engaged with it to rotate, and the gear 1 24 drives the screw 23 to rotate, further moving the extension plate 22 to the right, thereby adjusting the welding position of the welding head 27 so that the distance between the welding head 27 and the positioning block 17 is equal to the radius of the welding part 8. Finally, the staff starts the rotating cylinder 13. The operation of the rotating cylinder 13 drives the rotating plate 21 to rotate, so that the welding head 27 first spot welds the left and right sides of the welding part 8, and then performs girth welding on the welding part 8 to complete the welding operation.

[0028] The position of the welding part 8 is positioned by the positioning block 17, and when the positioning block 17 moves downward, the pressure rod 15 will press the spring 16 upward, and the elastic potential energy of the spring 16 will prevent the positioning block 17 from excessively squeezing the outer wall of the iron pipe 7. The elastic potential energy of the spring 20 will make the four groups of pressure plates 18 and the inner wall of the welding part 8 conflict with each other, so that the welding part 8 is always accurately fixed at the welding position of the iron pipe 7. Compared with the traditional device, the device determines the welding position of the welding part 8 by the positioning block 17, and firmly fixes the welding part 8 at the welding position of the iron pipe 7 by the four groups of pressure plates 18, effectively reducing the welding error, improving the stability of the device during welding, and improving the welding quality.

[0029] Among them, a guide rod 10 is fixedly installed on the top of the workbench 1, and the outer wall of the guide rod 10 is movably connected to the support platform 9. An iron pipe 7 is placed on the top of the support platform 9. The front and rear sides of the support platform 9 are threadedly connected with a screw rod 11, and the bottom of the screw rod 11 is rotatably installed on the top of the workbench 1.

[0030] The staff first fixes the iron pipe 7 directly below the welding head 27 and rotates the first screw rod 11. The rotation of the first screw rod 11 drives the support platform 9 sleeved with its thread to move upward along the guide rod 10, further enabling the support platform 9 to support the iron pipe 7 and ensuring the stability of welding.

[0031] By rotating the first screw rod 11, the support platform 9 moves upward along the guide rod 10, further enabling the support platform 9 to support the iron pipe 7. Compared with traditional devices, the stability of the iron pipe 7 during welding is ensured through the support of the support platform 9, avoiding the shaking and bending of the iron pipe 7 and improving the welding quality.

[0032] Among them, rubber pads are provided on the outer walls of the four groups of pressing plates 18, which are responsible for increasing the friction force on the welded part 8.

[0033] Among them, a rotating plate 21 is fixedly installed on the outer wall of the rotating rod 14. A second gear 25 is rotatably installed inside the rotating plate 21. The second gear 25 is fixedly connected to the knob 26, and the knob 26 is rotatably installed on the outer wall of the rotating plate 21.

[0034] Among them, a second screw rod 23 is rotatably installed inside the rotating plate 21. One end of the second screw rod 23 is fixedly connected to the first gear 24, and the first gear 24 meshes with the second gear 25.

[0035] The staff can rotate the knob 26 to make the second gear 25 drive the first gear 24 meshing with it to rotate, and the first gear 24 drives the second screw rod 23 to rotate.

[0036] Among them, an extension plate 22 is movably installed on the right side of the rotating plate 21. A welding head 27 is fixedly installed on the right side of the extension plate 22, and the extension plate 22 is threadedly sleeved with the second screw rod 23.

[0037] When the second screw rod 23 rotates, the extension plate 22 moves to the right, thereby adjusting the welding position of the welding head 27 to make the distance between the welding head 27 and the positioning block 17 equal to the radius of the welded part 8.

[0038] Among them, the welding mechanism 5 is connected to the welding head 27 and is responsible for controlling the welding of the welding head 27.

[0039] The working principle and usage process of the present utility model:

[0040] When it is necessary to weld the iron pipe 7 and the welding part 8, the staff first fixes the iron pipe 7 just below the welding head 27 and rotates the screw 11. The rotation of the screw 11 drives the support platform 9 with which it is threadedly sleeved to move upward along the guide rod 10, further allowing the support platform 9 to support the iron pipe 7 to ensure the stability of the welding. At this time, after the staff places the welding part 8 at the position where welding is required, the column 4 is moved to the vertical position of the welding part 8, so that the positioning block 17 and the welding part 8 are aligned. Then the staff starts the cylinder on the top of the column 4 to move the lifting platform 6 downward. At this time, the positioning block 17 passes through the center position of the welding part 8 and conflicts with the outer wall of the iron pipe 7 to complete the positioning. When the positioning block 17 moves downward, the pressure rod 15 will squeeze the spring 16 upward, and through the elastic potential energy of the spring 16, the positioning block 17 is prevented from excessively squeezing the outer wall of the iron pipe 7, avoiding the positioning block 17 The positioning operation affects the quality of the outer wall of the iron pipe 7. At this time, the positioning block 17 passes through the center of the welding part 8, and the four groups of pressure plates 18 conflict with the inner wall of the welding part 8 through the elastic potential energy of the spring 20, avoiding the positioning deviation caused by the excessive hole of the welding part 8, so that the welding part 8 is always accurately fixed on the welding position of the iron pipe 7. At this time, the staff can turn the knob 26 to make the gear 2 25 drive the gear 1 24 that is meshed with it to rotate, and the gear 1 24 drives the screw 2 23 to rotate, further moving the extension plate 22 to the right, thereby adjusting the welding position of the welding head 27 so that the distance between the welding head 27 and the positioning block 17 is equal to the radius of the welding part 8. Finally, the staff starts the rotating cylinder 13. The operation of the rotating cylinder 13 drives the rotating plate 21 to rotate, so that the welding head 27 first spot welds the left and right sides of the welding part 8, and then performs girth welding on the welding part 8 to complete the welding operation. 。
