Usually, it is necessary to grind or replace the electrode to meet the usage requirements. And welding spatter and electrode indentation will be generated during the welding process, which requires manual grinding. The cost is high and the efficiency is low. It does not meet the requirements of high efficiency and low cost required by the factory during mass production. Summary of the Utility Model

[0017] The exemplary embodiments of the present disclosure will be described in more detail with reference to the drawings below. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be completely conveyed to those skilled in the art.

[0018] See Figure 1The utility model provides a horizontal high-speed resistance welding production machine, including a bottom plate 1, a slot plate 2, a movable electrode 4, a fixed electrode 3 and a cylinder 5. The bottom plate 1 is a rectangular steel structure plate, and the slot plate 2 and the fixed electrode 3 are respectively arranged on the bottom plate 1. The slot plate 2 is a steel structure rectangular block, and the slot plate 2 is provided with multiple groups. The multiple groups of slot plates 2 are fixed with the bottom plate 1 to form a fixed slot, which can accommodate several workpieces of different sizes for welding at the same time. The fixed electrode 3 and the movable electrode 4 are a combination, and the two cooperate to weld thin-walled material parts. The fixed electrode 3 is a whole piece and is fixedly installed on the bottom plate 1. The movable electrode 4 is connected to the output shaft of the cylinder 5, and the movable electrode 4 is designed to be a special-shaped electrode according to the appearance of the welded workpiece.

[0019] It also includes a resistance welding controller 6, which is the control center of the entire special machine and controls the welding timing operation of the entire equipment. The resistance welding controller 6 is installed and fixed in the lower space of the base plate 1, and the primary alternating current used is converted into a secondary medium-frequency direct current during design. It has high thermal efficiency, short welding time, and can effectively avoid indentations on the surface of the workpiece after welding, making the workpiece more beautiful.

[0020] The bottom plate 1 is provided with connection holes, and the bottom plate 1 is connected to the slot plate 2 and the fixed electrode 3 through the connection holes and bolts, and the bottom plate 1 serves as a base for the slot plate 2 and the fixed electrode 3 .

[0021] There are four groups of movable electrodes 4 and cylinders 5 , and the movable electrodes 4 correspond to the cylinders 5 one by one and are arranged in parallel.

[0022] Cooling water holes are provided on both the fixed electrode 3 and the movable electrode 4. When the system starts to work and generates heat, cold water circulates through the cooling water holes to take away the heat and increase the service life of the electrodes. The cooling system also acts on the entire machine except the electrodes to ensure that the entire system operates at a suitable temperature and increase the service life of the machine.

[0023] During the use of the utility model, the control program can adjust each group separately to ensure the simultaneity of the movement of the movable electrode 4, so as to ensure that the pressure of the four movable electrodes 4 is consistent when they are pressed on the workpiece, and the strength of the weld point is consistent after welding. When the height of the workpiece is inconsistent, the welding size position can be adjusted by adjusting the movement stroke of the movable electrode 4 and replacing the movable electrode 4 to meet the welding requirements of different sizes.

[0024] When the resistance welding controller 6 is turned on to start working, the workpiece that needs resistance welding is placed in the fixed position formed by the slot plate 2 through the robot's transfer. The sensor senses and the cylinder 5 pushes the movable electrode 4. When the movable electrode 4 contacts the workpiece and forms a circuit with the fixed electrode 3, the power-on processing begins. After completion, the cylinder 5 drives the electrode back to its original position, forming a resistance welding process. At the same time, the cooling system works and acts on the entire special machine.

[0025] The above are only embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application.
