DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0018] In addition, in the application, the terms "first", "second" and other similar words are not intended to imply any order, quantity and importance, but are merely used to distinguish different elements. The terms "upper", "lower", "left", "right" and other similar words are merely positional relationships in the drawings.

[0019] like Figure 1As shown, the embodiment of the present application provides a stainless steel product butt positioning welding device, comprising: a first supporting platform 1, a second supporting platform 2, a first support plate 3, a second support plate 4, a moving platform 5 and a welding module 6; wherein the first supporting platform 1 and the second supporting platform 2 can be independently arranged or integrated, and when the first supporting platform 1 and the second supporting platform 2 are independently arranged, the distance between the first supporting platform 1 and the second supporting platform 2 can be adjusted according to the length of the pipe; the welding module 6 is installed on the first supporting platform 1 and / or the second supporting platform 2, and the position of the welding module 6 is located between the first supporting platform 1 and the second supporting platform 2; the first support plate 3 is installed on the second supporting platform 2, and the first support plate 3 can move linearly in the left and right directions, so as 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; the upper surface of the first support plate 3 A first material box 7 is provided on the side, and the first material box 7 is used to store the pipe A11 and supply the first pallet 3; a cylindrical groove is provided on the upper surface of the first pallet 3 for carrying the pipe A11, and similarly, a cylindrical groove is also provided on the upper surface of the second pallet 4 for carrying the pipe B12; the second pallet 4 is fixedly installed on the first supporting platform 1 or the second supporting platform 2, and a second material box 8 is provided above the second pallet 4, and the second material box 8 is used to store the pipe B12 and supply the second pallet 4; on the other hand, a movable mobile platform 5 is installed on the second supporting platform 2, and the moving direction of the mobile platform 5 is consistent with that of the first pallet 3, and a pushing module 13 is installed on the mobile platform 5, and the pushing module 13 is used to push the pipe B12 to the left side, 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, so that the pipe A11 and the pipe B12 are tightly connected; like Figure 2 As shown, a telescopic buckle 14 is provided in the groove, which is used to push 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 mobile 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 obstruction 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; when the pipe A11 is combined with the pipe B12, the welding module 6 starts to weld the pipe A11 and the pipe B12.

[0020] In one embodiment of the present application, Figure 3As shown, the pushing module 13 includes a top plate 131, a push plate 132, a connecting shaft 133 and an elastic member B134. The top plate 131 is cylindrical and can rotate along its axis. The top plate 131 is fixedly connected to the connecting shaft 133. The pushing plate 132 is arranged on the right side of the top plate 131. An elastic member B134 is arranged between the push plate 132 and the top plate 131, and a bearing is arranged between the elastic member B134 and the top plate 131. The pushing module 13 also includes a motor. A socket is arranged on the rotating shaft of the motor. The shape and size of the cross section of the socket are the same as the cross section of the connecting shaft 133. 133 is inserted into the rotating shaft of the motor. Theoretically, the shape of the cross section of the connecting shaft 133 can be any shape except a circle, so that the motor can drive the connecting shaft 133 to rotate while the connecting shaft 133 can also move linearly relative to the motor. With this arrangement, pressure can be applied to the pipe B12 through the top plate 131, the push 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 pipes B12 and A11 to rotate through the top plate 131, and then the entire circumferential surface can be welded without changing the position of the welding gun.

[0021] like Figure 2 As shown, in one embodiment of the present application, the telescopic buckle 14 can be telescoped up and down, a baffle 9 is installed on the first supporting platform 1, a blocking bearing 10 is installed in the baffle 9, and the baffle 9 can rotate. When the baffle 9 rotates to a specified position, the telescopic buckle 14 can be pressed down to retract the telescopic buckle 14, and after the telescopic buckle 14 is retracted, the blocking bearing 10 installed in the baffle 9 is concentric with the pipe A11, and when the baffle 9 is in the initial position, it will not block the radial movement of the pipe A11; with this arrangement, after the first support plate 3 transports the pipe A11 to the welding working position, the baffle 9 is driven by a motor to rotate until the bearing installed in the baffle 9 is concentric with the pipe A11, and at this time, the pushing module 13 is pushed to the left by the mobile platform 5, so that the pipe A11 is combined with the pipe B12; in this way, the friction force on the pipes A11 and B12 during rotation can be reduced, and the baffle 9 can support the pipes A11 and B12 more firmly than the telescopic buckle 14.

[0022] like Figure 4 As shown, in one embodiment of the present application, a rack 15 is installed under the first supporting platform 1, and the rack 15 is fixedly connected to the first pallet 3. A gear 16 meshing with the rack 15 is also provided under the first supporting platform 1. In this way, the rack 15 and the first pallet 3 can be driven to move linearly by rotating the gear 16.

[0023] like Figure 4As shown, in one embodiment of the present application, a connecting block A17 is fixedly connected below the first supporting platform 1, and a connecting block B51 is fixedly connected below the movable platform 5, a pull rod 52 is inserted in 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 limiting block 54, and an elastic member A53 is installed between the limiting block 54 and the connecting block B51; in this way, the movable platform 5 can be driven to move while the first support plate 3 moves, and after the first support plate 3 moves to the right to the welding working position, the baffle 9 falls down to block the pipe A11 from moving to the left, and then the first support plate 3 moves to the left. At this time, the movable platform 5 moves to the left with the first support plate 3, and when the pipe B12 is combined with the pipe A11, the top plate 131 stops moving under the obstruction of the pipe A11, and the first support plate 3 can continue to move to the left. At this time, the elastic member B13 4 and 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 pallet 3 stops moving, and the welding module 6 starts welding. After welding is completed, the first pallet 3 moves to the right again until the elastic member B134 returns to its initial state. Then, the baffle 9 is moved to the initial position, and the first pallet 3 is moved to the left again. At this time, the pipe A11 is no longer bound. Under the push of the top plate 131, the pipes A11 and B12 are pushed to the left until the mobile platform 5 contacts the second pallet 4. The mobile platform 5 stops moving, and the first pallet 3 continues to move to the left, so that the pipe A11 can fall from the first pallet 3 to the first supporting platform 1. The first pallet 3 continues to move to the left, and after the telescopic buckle 14 moves to the left side of the first material box 7, the pipe A11 can be filled into the first pallet 3 again.

[0024] It should be noted that when the first pallet 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 pallet 4 , and at this time the pipe B12 can be filled into the second pallet 4 through the second material box 8 .

[0025] like Figure 3 As shown, in one embodiment of the present application, the right end face of the first support plate 3 is an inclined surface. With this arrangement, 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.

[0026] like Figure 5 As shown, a cover 31 is provided on the top of the first support plate 3. The cover 31 is a sheet metal part of the same shape as the upper surface of the first support plate 3. A plurality of through holes are provided in the cover 31. 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, a cover 31 and a ball 32 are also installed on the upper surface of the second support plate 4.

[0027] like Figure 6 As shown, a plurality of rollers 33 are installed at the bottom of the first pallet 3 to reduce the friction 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 mobile platform 5 to reduce the friction between the mobile platform 5 and the second support platform 2.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
