In recent years, sandwich board, especially structural tube sandwich board, has gradually gained popularity due to its unique advantages. This type of board achieves the goal of significantly reducing overall weight while not sacrificing structural strength by embedding metal tubes between double-layer metal plates and welding them into shape.

The utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0042] Embodiment 1: An insertion pipe and welding mechanism for automatic welding production of structural pipe core material plate, which is connected to a pipe feeding device capable of continuously conveying metal pipe feed, and includes several sets and is divided into two groups and is installed on both sides of the base plate 4, each set includes an insertion pipe device 61 and a laser welding device 62, the insertion pipe device 61 and the laser welding device 62 can form relative displacement with the metal plate, the insertion pipe device 61 is connected with the pipe feeding device, can push and insert a single metal pipe 2 falling into the through hole 11 on the metal plate 1 into the supporting slot 42 on the top surface of the base plate 4, so that the metal pipe 2 is located between the relative through holes 11 of the two metal plates 1, the laser welding device 62 is used for welding the contact part between the metal pipe 2 and the metal plate 1, and each set of insertion pipe and welding mechanism 6 on both sides is opposite to each other, so that the insertion pipe device 61 on one side corresponds to the laser welding device 62 on the other side. In this embodiment, the pipe device is like Figure 7As shown, the metal pipe is sequentially fed into the metal pipe feeding groove 60, and the pipe feeding device can move with the displacement of the pipe inserting device 61, and continuously feed the metal pipe 2 in a flat state, and one metal pipe 2 can be fed at a time into the metal pipe feeding groove 60. The present application is not improved on the metal pipe 2 feeding mechanism, so the metal pipe 2 feeding mechanism is not described in detail in this embodiment. When the pipe inserting device 61 moves to the initial position, that is, aligns with the initial hole 11 on the metal plate 1, the outermost first hole 11 is taken as the initial hole 11 in this embodiment. After the pipe inserting device 61 is aligned with the initial hole 11, the pipe inserting device 61 inserts the metal pipe 2 into the initial hole 11 and continues to push in to make the metal pipe 2 enter the support slot 42 and stop after a part of the end face of the metal pipe 2 extends out of the corresponding hole 11 on the other side of the metal plate 1. At this time, the metal pipe 2 is just placed between the two metal plates 1, and the metal pipe 2 is just opposite the laser welding device 62 on the other side after being inserted into position. The laser welding device 62 on the other side immediately completes welding. At the same time, the pipe inserting device 61 on the other side inserts the metal pipe 2 into another hole 11, and the metal pipe 2 is welded by the laser welding device 62 on this side. That is, the pipe inserting and welding on both sides are synchronous and work together to complete the pipe inserting and welding of the metal pipes 2 in the first row.

[0043] Preferably, the translation mechanism includes a translation rail 64 mounted on the top of the gantry 31, a translation rack 65, a servo motor 66 mounted on the bottom plate 63, a gear on the output end of the servo motor 66 and the translation rack 65, and the bottom plate 63 mounted on the translation rail 64. Thus, the bottom plate 63 can slide along the translation rail 64 by rotating the gear, and the servo motor 66 drives the gear to rotate relative to the translation rack 65, thereby driving the bottom plate 63 to displace along the translation rail 64. The pipe inserting device 61 and the laser welding device 62 are mounted on the bottom plate 63. The servo motor 66 can drive the pipe inserting device 61 and the laser welding device 62 to continuously displace, stop between each adjacent support slot 42: the pipe inserting device 61 pushes the metal pipe 2 corresponding to each support slot 42 into the support slot 42 from the pipe feeding device; and the laser welding device 62 welds and fixes the metal pipe 2 in each support slot 42 to the metal plate 1. In this embodiment, the translation rail 64, the translation rack 65 and the servo motor 66 are prior art, and the purpose is to control the pipe inserting and welding mechanism 6 to displace, stop and displace again between each pipe inserting support slot.

[0044] Preferably, the first push rod mechanism 67 is installed on the bottom plate 63, and the insertion tube device 61 is connected with the push rod of the first push rod mechanism 67. When the translational mechanism drives the bottom plate 63 to move horizontally so that the insertion tube device 61 is aligned with the target through hole 11, the first push rod mechanism 67 is started to push the insertion tube device 61 towards the metal plate 1, so that the front end of the insertion tube device 61 is aligned with the through hole 11 of the metal plate 1 and contacts, and the insertion tube device 61 is aligned with the through hole 11. The insertion tube device 61 further comprises a second push rod mechanism 68, an insertion tube push head 69, a metal pipe feeding groove 70 and an insertion tube butt joint 60. The metal pipe feeding groove 70 can accommodate a falling metal pipe 2, the insertion tube butt joint 60 is located at the front end of the metal pipe feeding groove 70, and the insertion tube push head 69 is located at the rear end of the metal pipe feeding groove 70. After alignment, the insertion tube push head 69 is pushed horizontally under the action of the second push rod mechanism 68, so that the metal pipe 2 is pushed into the corresponding through hole 11 and enters the supporting slot 42. When the insertion tube push head 69 reaches the full stroke, the two ends of the metal pipe 2 are just located between the opposite through holes 11 of the two metal plates 1. Then, the second push rod mechanism 68, the insertion tube push head 69, the first push rod mechanism 67 and the insertion tube device 61 return to reset, waiting for the next insertion tube station. That is, the insertion tube device 61 can approach the metal plate 1 with the extension of the first push rod mechanism 67, so that the insertion tube butt joint 60 is aligned with the corresponding supporting slot 42 on the top of the base plate 4. The second push rod mechanism 68 is connected with the insertion tube push head 69, which can drive the insertion tube push head 69 to extend or retract. When extended, the metal pipe 2 in the metal pipe feeding groove 70 is pushed forward, and the metal pipe 2 finally enters the supporting slot 42 after passing through the insertion tube butt joint 60, and is just located between the through holes 11 of the two metal plates 1.

[0045] In the embodiment, the number of sets of the insertion tube and welding mechanism 6 and the number of sets of the pressing plate mechanism 5 can be allocated according to the length of the base plate 4, and multiple sets of the insertion tube and welding mechanism 6 are combined to completely match the base plate 4, the metal plate 1 and the metal pipe 2. Similarly, multiple sets of the pressing plate mechanism 5 can completely clamp the surface of the metal plate 1. The specific number is flexibly adjusted and arranged according to the size of the actual welded metal plate 1, so that each set of mechanism can be operated synchronously and cooperatively to complete the welding work.

[0046] It should be noted that in another embodiment, the insertion tube and welding mechanism 6 can not include a translational mechanism. When it is fixed, the relative displacement between the metal plate and the base plate can be formed to complete the insertion tube and welding work.

[0051] When the two metal plates 1 are respectively located on both sides of the base plate 4 and extend into position and stop, at this time, in order to make the metal plate 1 and the base plate 4 completely aligned, the positioning mechanism on the base plate 4 is needed to position the metal plate 1 on both sides, and the screen plate frame body of the base plate 4 is also provided with a plurality of positioning mechanisms, which are uniformly distributed on each key point, used to align the metal plate 1 relative to the base plate 4. The positioning mechanism includes a pneumatic mechanism, which can drive the positioning plug 43 at both ends to extend or retract. The shape and size of the positioning plug 43 are matched with the shape and size of the through hole 11 on the metal plate 1, and a beveled guide angle is arranged on the top edge of the positioning plug 43.
