[0005] Preferably, the fastening mechanism includes a buckle located on the surface of the support plate, and a fastening bolt and a fastening nut located on the buckle.

[0006] Preferably, a long plate fixedly connected to one side of the buckle is provided, the long plate is fitted to the surface of the cylinder, and a clamp is also provided on the surface of the cylinder, and the clamp presses the long plate.

[0007] Preferably, a plurality of the limit blocks are provided with anti-slip textures.

[0008] Preferably, the buckle is provided with a plurality of cuts evenly distributed on the support plate.

[0009] The utility model provides a welding tool for the outer ring plate of a circular tube, which has the following beneficial effects: it solves the problem of roundness problem of the original ring plate being welded first and then inserted into the cylinder, which requires hammering back and forth around and hard assembly, resulting in deformation of the ring plate; and the problem of secondary deformation caused by welding without constraints. It can effectively improve assembly efficiency and welding quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0014] In the description of the present invention, unless otherwise specified, "multiple" means two or more; the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third" and the like are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0015] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0016] See also Figure 1 to Figure 2 The utility model provides a technical solution: a welding tool for a group of circular tube outer ring plates 7, including a support frame 1, a welding mounting frame 2 fixedly connected to the top of the support frame 1, a welding head 3 at the bottom of the welding mounting frame 2, a plurality of support feet 4 provided below the welding head 3, a plurality of support feet 4 provided with fixedly connected limit blocks 5, and a plurality of limit blocks 5 provided with anti-slip textures. A cylinder 6 is provided on the limit block 5, a ring plate 7 is provided on the outer side of the cylinder 6, a support plate 8 is also sleeved on the surface of the ring plate 7, a fastening mechanism 9 is provided between the ring plate 7 and the support plate 8, and the fastening mechanism 9 includes a buckle 91 located on the surface of the support plate 8, and a fastening bolt and a fastening nut located on the buckle 91. A long plate 10 fixedly connected to the long plate 10 is provided on one side of the buckle 91, and the long plate 10 is attached to the surface of the cylinder 6. A clamp 11 is also provided on the surface of the cylinder 6, and the clamp 11 presses the long plate 10. The buckle 91 is provided with a plurality of cuts evenly distributed on the support plate 8.

[0017] The specific usage and function of this embodiment are as follows: first, the ring plate 7 is put on the outside of the cylinder 6, and multiple ring plates 7 are separately attached to the support plate 8; the buckle 91 is put on the ring plate 7 on the support plate 8 at the same time, and the ring plate 7 is fixed on the support plate 8 from one end of the buckle 91 with bolts, and multiple buckles 91 are evenly fixed, and then the long plate 10 of a circle of buckles 91 is all tightly held with a clamp. During rotation welding, there is a gap between the support plate 8 and the cylinder 6, which leaves space for the fillet welding of the ring plate 7. And because it is an overall constrained welding, the ring plate 7 is not easy to deform compared to the unconstrained state.
