[0049] The base plate 1 is preferably a flat plate structure having at least one upper surface in the shape of a plane. Preferably, the first component 2, the second component 3, the adjustment component 4, the first fixing component 6 and the second fixing component 7 are all arranged on the upper surface.

[0050] Preferably, the first component 2 and the second component 3 have the same structure and are symmetrically mirrored relative to the first position. In this embodiment, the specific structure of the first component 2 is emphasized; details are shown below.

[0051] The first fixing assembly 6 and the second fixing assembly 7 have the same structure and are symmetrically mirrored relative to the first position.

Preferably, there are multiple first fixing assemblies 6 and multiple second fixing assemblies 7, and the multiple first fixing assemblies 6 and the multiple second fixing assemblies 7 are symmetrically arranged relative to the first position.

[0052] The adjustment component 4 is used to make the first component 2 and the second component 3 move closer to the first position or move away from the first position at the same time; the structure of the adjustment component 4 is as follows:

[0053] like Figure 1-2 As shown, the first component 2 includes a first support portion 201, and the second component 3 includes a second support portion 301; the adjustment component 4 includes a first connecting rod 401, a rotating plate 402, a rotating component 403, and a second connecting rod 404, and the two ends of the rotating plate 402 are respectively a first end 405 and a second end 406; the two ends of the first connecting rod 401 are respectively rotatably connected to the first support portion 201 and the first end 405; the two ends of the second connecting rod 404 are respectively rotatably connected to the second support portion 301 and the second end 406; the rotating plate 402 is rotatably connected to the base plate 1 through the rotating component 403, and the connection between the rotating plate 402 and the rotating component 403 is located between the first end 405 and the second end 406; the first position is set on the central axis of the rotating component 403.

[0054] Preferably, the rotating component 403 is a bearing, such as a damping bearing; the two ends of the first connecting rod 401 are rotatably connected to the first support part 201 and the first end 405 respectively, and the rotatable connection is also formed by relying on the bearing component; the two ends of the second connecting rod 404 are rotatably connected to the second support part 301 and the second end 406 respectively, and the rotatable connection is also formed by relying on the bearing component. The rotatable connection form formed by bearings is already very mature and popular in the prior art and will not be elaborated here.

[0055] The connecting rod 9 is used to support the mesh surface of the mesh plate to be welded; the detachable connection formed by the connecting rod 9 and other components can be connected by screws or bolts, and the number of connecting rods 9 can be configured as multiple ones of different lengths; preferably, the connecting rod 9 extends along the direction indicated by the second straight line; a plurality of snap-fitting portions 901 are provided on the connecting rod 9, and a snap-fitting slot is provided on the mesh surface, and the snap-fitting portion 901 is snapped into the snap-fitting slot, thereby limiting the mesh surface.

[0056] The position of the first position can be configured according to specific circumstances. In this embodiment, after the various components of the mesh are installed on the mesh welding tooling, the first position is located below the center of the mesh surface of the mesh.

[0057] like Figure 1 , Fig.10 As shown, when in use, before welding, the various components of the mesh are set on the mesh welding tooling, and a pair of short sides of the mesh are clamped using the first component 2 and the second component 3, and a pair of long sides of the mesh are clamped using the first fixing component 6 and the second fixing component 7, and the mesh surface is supported by the connecting rod 9; after clamping, the adjacent components of the mesh are welded until they are welded into one; when disassembling, the first component 2 and the second component 3 loosen a pair of short sides of the mesh, and the first fixing component 6 and the second fixing component 7 loosen a pair of long sides of the mesh, and the welded finished mesh is removed.

[0058] As can be seen from the background technology, the technical problem existing in the prior art is how to provide a new mesh plate welding tool that can clamp and fix mesh plates of different sizes.

[0059] In this embodiment, along the direction indicated by the first straight line, the first component 2 and the second component 3 can be simultaneously close to or away from each other through the adjustment component 4, and the first component 2 and the second component 3 are used to fix a pair of short sides of the mesh plate to be welded; along the direction indicated by the second straight line, the first fixing component 6 and the second fixing component 7 can be close to or away from each other, and the first fixing component 6 and the second fixing component 7 are used to fix a pair of long sides of the mesh plate to be welded; and then when matching mesh plates of different sizes, along the direction indicated by the first straight line, by adjusting the distance between the first component 2 and the second component 3 relative to the first position through the adjustment component 4, and then adjusting the distance between the first fixing component 6 and the second fixing component 7 relative to the first position, two sets of opposite sides of mesh plates of different sizes can be fixed; further, the mesh surface is supported by the connecting rod 9, thereby realizing the clamping and fixing of various parts of the mesh plate. Therefore, this embodiment solves the technical problem of how to propose a new mesh plate welding tool in the prior art, which can clamp and fix mesh plates of different sizes.

[0060] Furthermore, in this embodiment, only one adjustment component 4 is needed to make the first component 2 and the second component 3 move simultaneously and move closer to or farther from the first position, thereby avoiding the use of two components to separately control the movement of the first component 2 and the second component 3. This embodiment saves the use of parts through ingenious design.

[0061] Furthermore, it is mentioned in the foregoing that the first component 2 and the second component 3 are moved closer to or farther from each other through the adjustment component 4, and the staff can manually apply a force to make the first component 2 and the second component 3 move through the adjustment component 4, or the power component can apply the force; in this embodiment, in order to facilitate the staff, the power component is used to apply the force; details are shown in the following scheme:

[0062] The mesh plate welding tool also includes a power component 5, which is used to drive the first component 2 or the second component 3 to move along the direction indicated by the first straight line.

[0063] In this embodiment, preferably, the power component 5 is a linear motor. Furthermore, in other optional embodiments, the power component 5 can also be a cylinder. The casing of the linear motor is installed on the base plate 1, and the output shaft of the linear motor is connected to the first support part 201, and the power component 5 is connected to the main controller. Through the main controller, the start, operation and stop of the linear motor can be remotely controlled, which is more convenient and avoids the situation where the staff manually applies force, thus eliminating labor costs.
