[0022] The present application is further described in detail below in conjunction with the accompanying drawings.

[0023] A welding machine table, referring to Figure 1 and Figure 2 , including a workbench 10 for placing steel plates and installing accessory parts, the upper surface of the workbench 10 is a flat plane, the top of the workbench 10 has a welding area 12 and two placement areas 11 for placing steel plates, the welding area 12 is located between the two placement areas 11, and the placement area 11 is also provided with an electrode 13, when the steel plate is placed in the placement area 11, the electrode 13 forms an electrical connection with the steel plate;

[0024] A pressing assembly 20 for pressing the steel plate is arranged in the placement area 11. The pressing assembly 20 includes a mounting frame 21 mounted on the workbench 10. A telescopic rod 22 is mounted on the mounting frame 21. The telescopic rod 22 may be an electric cylinder or a hydraulic cylinder. A pressing plate 23 is mounted on the telescopic head of the telescopic rod 22. The bottom of the pressing plate 23 is a plane. When the telescopic rod 22 extends out of the telescopic head, the pressing plate 23 moves toward the placement area 11 of the workbench 10. In the assembled state and the moving state, the bottom plane of the pressing plate 23 is always parallel to the plane of the placement area 11 on the upper surface of the workbench 10. When the steel plate is placed in the placement area 11, the telescopic rod 22 may extend out of the telescopic head so that the pressing plate 23 is in close contact with the upper surface of the steel plate.

[0025] A welding mechanism 30 for holding the welding rod is arranged above the welding area 12. The welding mechanism 30 has contacts for energizing the welding rod. The distance and position relationship between the welding mechanism 30 and the workbench 10 are adjustable. When the steel plate is placed in the placement area 11, the contacts of the welding structure can be electrically connected with the steel plate through the welding rod and the electrode 13.

[0026] The following is a further introduction based on specific usage scenarios.

[0027] When in use, the operator places the two steel plates to be welded in the two placement areas 11 respectively, and makes the places where the two steel plates to be welded are in the welding area 12. Then the operator opens the telescopic rods 22 in the two placement areas 11, and the telescopic rods 22 extend the telescopic heads to move the pressing plate 23 toward the steel plates until the lower surface of the pressing plate 23 is in close contact with the upper surface of the steel plates. At this time, the operator can open the welding mechanism 30 to make the welding rod supported by the welding structure weld the parts to be connected of the two steel plates. Since the steel plates are in contact with the electrode plates 13, the contacts of the welding mechanism 30 are electrically connected with the electrode plates 13, and the welding rods can normally strike an arc at the welding points of the two steel plates.

[0028] When welding, since the upper and lower surfaces of the steel plate are respectively in close contact with the pressure plate 23 and the upper surface of the workbench 10, the steel plate is actually clamped by the pressure plate 23 and the workbench 10, and the rigid limiting method is used to prevent the steel plate from undergoing large deformation. In addition, the steel plate is in close contact with the pressure plate 23 and the workbench 10, and the workbench 10 and the pressure plate 23 can quickly conduct the heat of the steel plate to the surrounding air, reducing the heat accumulation effect of the steel plate caused by welding, and further reducing the deformation tendency of the steel plate.

[0029] The unwelded steel plate has better flatness and can be better clamped by the pressing plate 23 and the workbench 10. When the steel plate has poor flatness, the force applied to the pressing plate 23 by the telescopic rod 22 can also make the steel plate flat. During welding, the steel plate becomes soft due to heat, and the force applied to the steel plate by the pressing plate 23 can further flatten the steel plate.

[0030] In general, the embodiments of the present application apply pressure to the steel plate during welding, reduce the deformation of the steel plate through rigid limiting, and the workbench 10 and the pressure plate 23 that play the role of rigid limiting can also prevent heat accumulation in the steel plate, reduce the bending deformation of the steel plate during welding, and keep the steel plate flat.

[0031] In some possible implementations of the embodiments of the present application, refer to Figure 2 The welding mechanism 30 includes a manipulator 31 for holding the welding rod, and the contact is located on the manipulator 31. The distance and angle between the end of the manipulator 31 close to the workbench 10 and the workbench 10 are adjustable. A guide rail 32 is also provided on the workbench 10. The guide rail 32 is fixedly connected to the workbench 10 through a connecting rod 33. The manipulator 31 can slide on the guide rail 32, so that the position of the manipulator 31 and the workbench 10 can be adjusted.

[0032] As a feasible specific implementation method of the present application embodiment, refer to Figure 3 A plurality of heat sinks 24 are arranged on the side of the pressing plate 23 away from the workbench 10. The heat sinks 24 and the pressing plate 23 are thermal conductors, which increase the contact area with the surrounding air, thereby being able to quickly remove the heat of the steel plate, reduce the heat accumulation effect of the steel plate, and further reduce the bending deformation of the steel plate during welding.

[0033] In a possible implementation of the embodiment of the present application, the extension line of the connection line at both ends of the heat sink 24 does not pass through the welding area 12. In terms of shape, the welding area 12 is in the shape of an elongated strip. When the cross-sectional plane is parallel to the upper surface of the workbench 10, the connection line between the two ends of the long axis of the cross-section of the elongated welding area 12 is parallel to the connection line at both ends of the heat sink 24. In this way, the side of the heat sink 24 can isolate the welding area 12, reducing the amount of heat from the welding area 12 diffusing away from the welding area 12. In this way, the flowing air away from the welding area 12 can quickly take away the heat from the steel plate, avoiding the steel plate and most of the heat sink 24 from being covered by the high-temperature gas in the welding area 12, further reducing the bending deformation of the steel plate during welding.

[0034] In a possible implementation of the embodiment of the present application, a plurality of heat sinks 24 are also provided at the bottom of the workbench 10, so that the heat at the top and bottom of the steel plate can be quickly removed, further reducing the bending deformation of the steel plate during welding.

[0035] As a feasible specific implementation method of the embodiment of the present application, a through hole 25 is provided in the middle of the pressing plate 23, and the through hole 25 is far away from the welding area 12. The volume of the steel plate increases after being heated, and the through hole 25 in the middle of the pressing plate 23 can play a role similar to a riser. When the volume of the steel plate increases slightly after being heated, it can enter the through hole 25. After the steel plate cools down, the material inside the through hole 25 retreats, which can reduce the deformation of the steel plate extending to the surrounding areas.

[0036] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
