Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0027] Embodiment one

[0028] As Figure 1 , Figure 2 , Figure 4 and Figure 5 ​As shown, this embodiment proposes a clamping device for welding electric welded wire mesh, including a device base 1 with a limiting post 8 fixed at the top, and a rotating rod 9 rotatably inserted in the limiting post 8. A disc 4 is fixedly sleeved on the surface of the rotating rod 9, and a rack 2 meshes with the surface of the disc 4. A round rod 13 is fixedly inserted in the rack 2, and a sleeve post 12 is fixedly sleeved on the surface of the round rod 13. An electric push rod 11 is installed on one side of the sleeve post 12. Arc-shaped grooves 14 are opened on both sides of the inner wall of the device base 1, and the round rod 13 is slidably inserted in the arc-shaped grooves 14. A square groove 3 is opened at the top of the device base 1, and two sets of square grooves 3 are symmetrically opened. A rack 2 is slidably inserted in the two sets of square grooves 3. Multiple sets of teeth are provided on the surface of the disc 4, and the multiple sets of teeth are distributed in a semi-circle around the disc 4. Multiple sets of limiting posts 8 are symmetrically arranged, and a rotating rod 9 is slidably inserted in every two sets of limiting posts 8.

[0029] The electric actuator 11 used in this application is a product that can be purchased directly from the market. Its principle and connection method are existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0030] In the above embodiment, during use, after the welding of one side of the metal mesh is completed, the electric push rod 11 is activated. The piston end of the electric push rod 11 pushes the sleeve column 12 and the round rod 13 forward, so that the two sides of the round rod 13 slide forward in the arc groove 14. Then, the two sets of racks 2 slide forward in the square groove 3. As the racks 2 move, the meshing disc 4 and the rotating rod 9 rotate in the limiting column 8. Finally, as the rotating rod 9 rotates, it drives the connecting column 5 and the metal mesh to rotate 180°, so that the back side of the metal mesh can be welded.

[0031] Example 2

[0032] like Figure 3 As shown, based on the same concept as the above embodiment, this embodiment also proposes: a connecting post 5 is fixed on one side of the rotating rod 9, and a bidirectional threaded rod 6 is rotatably inserted into the connecting post 5. The two sides of the surface of the bidirectional threaded rod 6 are fitted with movable posts 10 through thread rotation, and a clamping block 7 is fixed on one side of the movable post 10; the surface of the clamping block 7 is inclined, and a rubber pad is laid on the inner side of the clamping block 7; multiple sets of clamping blocks 7 are provided, and every two sets of clamping blocks 7 are symmetrically arranged; the movable posts 10 are symmetrically arranged in the connecting post 5, and the movable posts 10 are slidably inserted into the connecting post 5.

[0033] In the above embodiment, the two ends of the metal mesh are placed between the two sets of clamping blocks 7 respectively. Then, the two sets of bidirectional threaded rods 6 are rotated clockwise according to the thickness of the metal mesh. The rotation of the bidirectional threaded rods 6 drives the two sets of moving columns 10 to rotate towards the middle at the same time. The rotation of the moving columns 10 drives the clamping blocks 7 to move towards the middle at the same time to clamp the metal mesh. After moving to the appropriate position, the rotation of the clamping blocks 7 is stopped. When it is necessary to increase the clamping thickness, the bidirectional threaded rods 6 can be rotated in the opposite direction.

[0034] Finally, it should be noted that: first, in the description of the present application, it should be noted that, unless otherwise specified and limited, the term "installation", "connected", "connection" should be broadly understood, can be mechanical or electrical connection, but also can be two elements inside the communication, can be directly connected, "up", "down", "left", "right" and so on, only for indicating the relative position relationship, when the absolute position of the described object changes, the relative position relationship may change;
