[0020] 1. By setting a positioning mechanism, two workpieces to be welded are placed close to the first positioning plate and the second positioning plate. The first positioning block is driven by the first motor to be close to the side wall of the workpiece, and the workpiece is extruded and positioned in the front and rear directions. When the driving block contacts the surface of the contact block, the second positioning block is driven to move downward synchronously through the driving frame, so that the workpiece is extruded and positioned in the vertical direction.

[0022] 3. By setting up a preheating mechanism, the workpieces on both sides are moved close to the first positioning plate and the second positioning plate respectively. When the workpiece contacts the wedge surface of the wedge-shaped positioning block, the workpiece continues to be moved until the wedge-shaped positioning block is retracted into the inner cavity of the operating table to complete the docking of the workpieces on both sides.

[0047] Reference Figure 1-Figure 12 As shown, in a preferred embodiment, a preheating mechanism 9 is installed on the surface of the operating table 1 for preheating the welding part of the workpiece. The preheating mechanism 9 includes a wedge-shaped positioning block 901 and a heating copper sheet 905. The wedge-shaped positioning block 901 is symmetrically slidably installed in the inner cavity of the operating table 1. A heating copper sheet 905 is installed on the surface of the wedge-shaped positioning block 901 for preheating the workpiece. During the welding process, the temperature difference between the workpiece and the welding area usually leads to the concentration of thermal stress, especially when welding thick materials and high-strength alloys. By preheating, the temperature difference between the welding area and the workpiece can be reduced, thereby reducing cracks caused by thermal stress.

[0049] In a preferred embodiment, when pre-positioning the workpieces, the workpieces on both sides are moved close to the first positioning plate 701 and the second positioning plate 702 respectively. When the workpieces contact the wedge surface of the wedge-shaped positioning block 901, the workpieces continue to be moved until the wedge-shaped positioning block 901 is retracted into the inner cavity of the operating table 1, and the docking of the workpieces on both sides is completed. At this time, the first contact 906 and the second contact 907 are closed, so that the heating copper sheet 905 is turned on, and the workpiece surface is automatically preheated to reduce the temperature difference between the welding area and the workpiece, thereby reducing cracks caused by thermal stress.

[0050] Specifically, the working principle of the welding equipment for the production of new materials is as follows: when in use, two workpieces to be welded are placed close to the first positioning plate 701 and the second positioning plate 702, and the first motor 708 can drive the first screw rod 707 to rotate, thereby driving the second positioning plate 702 and the mounting seat 703 to move synchronously, so that the first positioning block 709 is close to the side wall of the workpiece, and the workpiece is squeezed and positioned in the front and rear directions. As the mounting seat 703 moves, when the driving block 720 contacts the surface of the contact block 721, the first The connecting rod 718 moves downward, thereby driving the second positioning block 713 to move downward synchronously through the driving frame 717, thereby extruding and positioning the workpiece in the vertical direction. In addition, when the first connecting rod 718 moves downward, it drives the first piston 725 to move downward synchronously, thereby injecting the air in the air cavity 724 into the elastic airbag 723, making the elastic airbag 723 larger, pushing the two groups of slides 711 to move closer to each other, driving the second positioning block 713 to move synchronously, and pushing the workpieces on both sides toward the middle, so that the workpieces on both sides can fit tightly, thereby increasing welding accuracy.

[0051] When pre-positioning the workpieces, move the workpieces on both sides close to the first positioning plate 701 and the second positioning plate 702 respectively. When the workpieces contact the wedge surface of the wedge-shaped positioning block 901, continue to move the workpieces until the wedge-shaped positioning block 901 is retracted into the inner cavity of the operating table 1, and the docking of the workpieces on both sides is completed. At this time, the first contact 906 and the second contact 907 are closed, so that the heating copper sheet 905 is turned on, and the workpiece surface is automatically preheated to reduce the temperature difference between the welding area and the workpiece, thereby reducing cracks caused by thermal stress.

[0052] At the same time, after the workpiece is pre-positioned, the first motor 708 drives the mounting seat 703 to move. When the workpiece is re-positioned, the second positioning plate 702 is driven to move backward synchronously through the second threaded block 706, thereby driving the second connecting rod 805 and the second piston 804 to move, and the flux in the cavity 803 is injected into the telescopic hose through the second one-way valve 807, and sprayed onto the weld surface by the nozzle 802, so as to achieve synchronous application of the flux to prevent oxidation of the metal surface during welding, especially aluminum alloy, titanium alloy, copper alloy, etc., which are easy to react with oxygen in the air to form oxides during welding, which will affect the quality and strength of the welded joint. The flux forms a protective barrier to reduce the contact between the metal surface and oxygen, thereby avoiding oxidation and pollution, and can reduce the component of metal surface tension, improve the fluidity of the solder, help the solder to be evenly distributed in the joint area, and ensure the continuity and strength of the welded joint.

[0053] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
