[0027] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present application.

[0028] In addition, in the application, the terms "first", "second" and other similar terms do not intend to imply any order, quantity and importance, but are only used to distinguish different elements. The terms "upper", "lower", "left", "right" and other similar terms are only the positional relationships in the drawings.

[0029] Such as Figure 1As shown in the figure, an embodiment of the present application provides a butt joint positioning welding device for stainless steel products, including: a first support platform 1, a second support platform 2, a first pallet 3, a second pallet 4, a moving platform 5, and a welding module 6; wherein, the first support platform 1 and the second support platform 2 can be independently arranged or integrally arranged. When the first support platform 1 and the second support platform 2 are independently arranged, the distance between the first support platform 1 and the second support platform 2 can be adjusted according to the length of the pipe; the welding module 6 is installed on the first support platform 1 and / or the second support platform 2, and the position of the welding module 6 is located between the first support platform 1 and the second support platform 2; the first pallet 3 is installed on the first support platform 1, and the first pallet 3 can move linearly in the left-right direction to drive the pipe A11 to move to the welding working area, and the welding working area is the area where the welding module 6 is located; above the first pallet 3, there is a first material box 7, and the first material box 7 is used to store the pipe A11 and supply materials to the first pallet 3; the upper surface of the first pallet 3 is provided with a cylindrical groove for carrying the pipe A11. Similarly, the upper surface of the second pallet 4 is also provided with a cylindrical groove for carrying the pipe B12; the second pallet 4 is fixedly installed on the first support platform 1 or the second support platform 2, and above the second pallet 4, there is a second material box 8, and the second material box 8 is used to store the pipe B12 and supply materials to the second pallet 4; on the other hand, a movable moving platform 5 is installed on the second support platform 2, the moving direction of the moving platform 5 is the same as that of the first pallet 3, and a pushing module 13 is installed on the moving platform 5. The pushing module 13 is used to push the pipe B12 to the left, so that the pipe B12 is combined with the pipe A11, and a rated pressure is applied to the pipe A11 and the pipe B12 to make the pipe A11 and the pipe B12 closely connected;

[0030] As Figure 2 shown, a telescopic buckle 14 is provided in the groove for pushing the pipe A11 to move. When the first pallet 3 moves to the left until the telescopic buckle 14 is located on the left side of the first material box 7, the pipe A11 stored in the first material box 7 falls into the first pallet 3. When the first pallet 3 moves to the right, the telescopic buckle 14 pushes the pipe A11 to move to the right; when the first pallet 3 moves to the designated welding working position, the moving platform 5 drives the pushing module 13 to move to the left until the pipe B12 is combined with the pipe A11. Due to the blockage of the telescopic buckle 14, the pipe A11 cannot move to the left, so that the pipe A11 can be combined with the pipe B12; after the pipe A11 and the pipe B12 are combined, the welding module 6 starts to weld the pipe A11 and the pipe B12.

[0031] In an embodiment of the present application, as Figure 3As shown in the figure, the pushing module 13 includes a top plate 131, a pushing plate 132, a connecting shaft 133, and an elastic member B134. The top plate 131 is cylindrical and rotatable along its axis. The top plate 131 is fixedly connected to the connecting shaft 133. The pushing plate 132 is disposed on the right side of the top plate 131. An elastic member B134 is provided between the pushing plate 132 and the top plate 131. And a bearing is provided between the elastic member B134 and the top plate 131. The pushing module 13 further includes a motor. A jack is provided on the rotating shaft of the motor. The shape and size of the cross-section of the jack are the same as those of the cross-section of the connecting shaft 133. The connecting shaft 133 is inserted into the rotating shaft of the motor. Theoretically, the shape of the cross-section of the connecting shaft 133 is any shape other than a circle. In this way, it can be ensured that while the motor drives the connecting shaft 133 to rotate, the connecting shaft 133 can also move linearly relative to the motor. With such a setting, pressure can be applied to the pipe B12 through the top plate 131, the pushing plate 132, and the elastic member B134, so that there is sufficient static friction between the pipe B12 and the top plate 131, thereby driving the pipe B12 and the pipe A11 to rotate through the top plate 131, and then the entire circumferential surface can be welded without changing the position of the welding torch.

[0032] As Figure 2 shown, in an embodiment of the present application, the telescopic buckle 14 can be telescoped up and down. A baffle 9 is installed on the first support platform 1. A blocking bearing 10 is installed in the baffle 9. The baffle 9 is rotatable. When the baffle 9 rotates to a specified position, it can press down the telescopic buckle 14 to make the telescopic buckle 14 retract. And after the telescopic buckle 14 retracts, the blocking bearing 10 installed in the baffle 9 is concentric with the pipe A11. When the baffle 9 is in the initial position, it will not block the radial movement of the pipe A11. With such a setting, after the first pallet 3 transports the pipe A11 to the welding working position, the motor can be driven to rotate the baffle 9 until the bearing installed in the baffle 9 is concentric with the pipe A11. At this time, the pushing module 13 is pushed to the left by the moving platform 5 to combine the pipe A11 and the pipe B12. In this way, the friction force suffered by the pipe A11 and the pipe B12 during rotation can be reduced, and the baffle 9 can support the pipe A11 and the pipe B12 more firmly relative to the telescopic buckle 14.

[0033] As Figure 4 shown, in an embodiment of the present application, a rack 15 is installed under the first support platform 1. The rack 15 is fixedly connected to the first pallet 3. A gear 16 meshing with the rack 15 is further provided under the first support platform 1. In this way, the rack 15 and the first pallet 3 can be driven to move linearly by the rotation of the gear 16.

[0034] As Figure 4As shown, in an embodiment of the present application, a connecting block A17 is fixedly connected below the first support platform 1, and a connecting block B51 is fixedly connected below the moving platform 5. A pull rod 52 is inserted into the connecting block B51. One end of the pull rod 52 is fixedly connected to the connecting block A17, and the other end of the pull rod 52 is fixedly connected to a limit block 54. An elastic member A53 is installed between the limit block 54 and the connecting block B51. In this way, the moving platform 5 can be driven to move while the first support plate 3 moves. After the first support plate 3 moves to the right to the welding working position, immediately, the baffle 9 drops to block the pipe A11 from moving to the left. Subsequently, the first support plate 3 moves to the left. At this time, the moving platform 5 moves to the left together with the first support plate 3. When the pipe B12 is combined with the pipe A11, the top plate 131 stops moving under the block of the pipe A11, while the first support plate 3 can continue to move to the left. At this time, the elastic member B134 and the elastic member A53 are compressed, and the pressure of the top plate 131 on the pipe B12 continues to increase. When the pressure of the top plate 131 on the pipe B12 reaches the rated pressure, the first support plate 3 stops moving, and the welding module 6 starts to perform welding work. After welding is completed, the first support plate 3 moves to the right again until the elastic member B134 returns to its initial state. Subsequently, the baffle 9 is moved to the initial position, and the first support plate 3 is moved to the left again. At this time, the pipe A11 is no longer restricted. Under the push of the top plate 131, the pipes A11 and B12 are pushed to the left until the moving platform 5 contacts the second support plate 4 and the moving platform 5 stops moving. The first support plate 3 continues to move to the left, and the pipe A11 can be dropped from the first support plate 3 onto the first support platform 1. The first support plate 3 continues to move to the left. After the expansion buckle 14 moves to the left side of the first material box 7, the pipe A11 can be filled into the first support plate 3 again.

[0035] It should be noted that when the first support plate 3 drives the pipe A11 to move to the welding working position, the top plate 131 is located on the left side of the second support plate 4. At this time, the pipe B12 can be filled into the second support plate 4 through the second material box 8.

[0036] As Figure 3 shown, in an embodiment of the present application, the right end surface of the first support plate 3 is an inclined surface. With such a setting, when the first support plate 3 moves to the right, the pipe A11 dropped on the first support platform 1 can be pushed to the rear side of the first support platform 1.

[0037] As Figure 5 shown, a cover 31 is provided on the top of the first support plate 3. The cover 31 is a sheet metal part having the same shape as the upper surface of the first support plate 3. A plurality of through holes are provided in the cover 31, and a ball 32 is provided in each through hole. In this way, the friction between the pipe A11 and the first support plate 3 can be reduced. Similarly, the cover 31 and the balls 32 are also installed on the upper surface of the second support plate 4.

[0038] As Figure 6 shown, a plurality of rollers 33 are installed at the bottom of the first pallet 3 to reduce the frictional force between the first pallet 3 and the first support platform 1; similarly, a plurality of rollers 33 are also installed at the bottom of the moving platform 5 to reduce the frictional force between the moving platform 5 and the second support platform 2.

[0039] Finally, it should be noted that the above are only preferred embodiments of the present application and are not used to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
