[0017] The following further elaborates on the present application in conjunction with the attached Figures 1-4 drawings.

[0018] The application embodiment discloses a welding device for a metal platform chassis, including a rotating rod 1. There are two groups of rotating rods 1, and the two groups of rotating rods 1 are cross-rotationally connected through a first rotating shaft 2. Both sides of the rotating rod 1 are rotationally connected with a clamping seat 3 through a second rotating shaft 5. Through grooves 10 are arranged on the upper surfaces of the clamping seats 3. A telescopic mechanism is arranged on one side of the clamping seat 3 corresponding to the through groove 10, and a side baffle 4 is fixedly connected to the moving end of the telescopic mechanism.

[0019] Furthermore, the two groups of rotating rods 1 are centrosymmetric with respect to the first rotating shaft 2. When the clamping seats 3 are properly positioned, the two groups of clamping seats 3 on the rotating rod 1 are symmetrically arranged.

[0020] Furthermore, the bottom of the side baffle 4 is a supporting portion. The supporting portion of the side baffle 4 is arranged in an inverted L shape, and the upper surface of the supporting portion of the side baffle 4 is flush with the bottom surface of the through groove 10.

[0021] In this embodiment, the two sets of rotating rods 1 arranged in an alternating manner can be regarded as the diagonals of the metal platform chassis. During welding, according to the actual size of the metal platform chassis, the angles of the two sets of rotating rods 1 are adjusted, and the rotating card holder 3 is rotated through the second rotating shaft 5 to align the through slots 10 on the two card holders 3 on the same side. Then, the two main rods forming the metal platform chassis are sequentially placed inside the through slots 10 on the card holders 3 on both sides of the rotating rod 1, and the two auxiliary rods forming the metal platform chassis are sequentially placed on the upper surface of the supporting part on the side baffle 4, and the position of the auxiliary rod is adjusted by using the telescopic mechanism so that the two auxiliary rods abut against the middle main rod.

[0022] In this embodiment, by providing mechanisms such as the rotating rod 1, the card holder 3, and the side baffle 4, the main and auxiliary rods forming the metal platform chassis can be spliced and supported before welding, improving the welding accuracy when welding the metal platform chassis.

[0023] Furthermore, the telescopic mechanism includes a connecting plate 6. One side of the connecting plate 6 is fixedly connected to the card holder 3, and the other side of the connecting plate 6 extends outside the rotating rod 1. And a sleeve 7 is fixedly connected to the end of the connecting plate 6 away from the rotating rod 1. An inner rod 8 is slidably installed inside the sleeve 7, and one end of the inner rod 8 is fixedly connected to the side baffle 4. A spring 9 is sleeved on the surface of the inner rod 8. One end of the spring 9 is fixedly connected to the sleeve 7, and the other end of the spring 9 is fixedly connected to the side baffle 4.

[0024] Furthermore, when the inner rod 8 moves outwards based on the sleeve 7, the spring 9 is in a stretched state.

[0025] In this embodiment, by providing the telescopic mechanism, it can be adaptively adjusted according to the length of the main rod of the metal platform chassis. Specifically, when the inner rod 8 is moved out of the sleeve 7, the overall length of the telescopic mechanism becomes longer. At this time, the spring 9 is stretched, and the spring 9 has a pulling force on the side baffle 4, causing the side baffle 4 to clamp the auxiliary rod tightly, so that the auxiliary rod is close to the main rod.

[0026] Finally, several points should be noted: First, in the description of the present application, it should be noted that unless otherwise specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense, which can be a mechanical connection or an electrical connection, or the communication inside two components, and can be directly connected. "Up", "down", "left", "right", etc. are only used to represent the relative position relationship. When the absolute position of the described object changes, the relative position relationship may change;
