Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

The bottom wall of the welding groove 3 is rotatably connected to two rotating discharging plates 7. The rear side of the workbench 1 is fixedly connected with a pressure support plate 8, the inner top wall of the pressure support plate 8 is fixedly connected with a telescopic column 9, the bottom end of the telescopic column 9 is fixedly connected with a conductive plate 10, the conductive plate 10 is electrically connected to the two rotating discharging plates 7, and the conductive plate 10 is electrically connected to the two rotating discharging plates 7. The front inner wall of the workbench 1 is rotatably connected with two rotating rods 11, the rear ends of the two rotating rods 11 are fixedly connected with support blocks 12, and the bottom walls of the two rotating discharging plates 7 are fixedly connected with limiting strips 13. The front and rear sides of the workbench 1 are provided with a cooling mechanism 2;

[0040] Specifically, a welding groove 3 is installed on the inner wall of the workbench 1 to accommodate the stamping parts to be welded, and a feed groove 4 is designed on the left side of the workbench 1 to facilitate the introduction of the stamping parts and nuts into the welding groove 3. After the stamping parts and nuts enter the welding groove 3 through the feed groove 4, the push rod 5 drives the push plate 6 to move forward and accurately push the stamping parts to the center position of the welding groove 3. The nut is manually placed at the position where the stamping parts need to be welded. The conductive plate 10 is connected to the pressurized support plate 8 through the telescopic column 9, and the rotating discharge plate 7 not only supports and guides the welded parts, but also forms an electrical connection with the conductive plate 10, becoming a loop part of the welding current. When the push plate 6 pushes the stamping parts to the center position of the welding groove 3, the high-intensity current generated between the conductive plate 10 and the rotating discharge plate 7 passes through the stamping parts and nuts. High temperature is generated instantly to fuse the stamping parts and the nut, achieving the welding purpose.

A sufficient amount of coolant is added to the cooling pool 202 to absorb and take away the heat generated by the stamping parts during welding. The bracket carrier 203 serves as a support platform for the conveying motor 204. After the conveying motor 204 is started, it drives multiple transmission shafts 205 to rotate through its output end, thereby driving the transmission belt 206 on the outer wall of the transmission shaft 205 to circulate, ensuring that the stamping parts and nuts after welding can move with the transmission belt 206. The front and rear ends of the middle transmission shaft 205 are also rotatably connected with bending wheels 207 for adjusting the transmission direction of the transmission belt 206, so that the left half of the transmission belt 206 ensures that the stamping parts and nuts can be more effectively in contact with the coolant during transmission, while the right half can smoothly move the stamping parts and nuts out of the cooling pool 202, thereby achieving rapid cooling of the stamping parts and nuts after welding.

[0044] Specifically, the operating table 14 serves as a centralized control panel for the entire equipment. The transmission motor 204 and the transformer 16 can be switched on and off and controlled respectively through the multiple operating buttons 15 on the top of the operating table 14. The transformer 16 is responsible for converting the input power into a voltage and current suitable for spot welding operations. The conductive wire 17 at its output end can ensure that the power can be transmitted to the conductive plate 10 and the rotating discharge plate 7 to ensure the normal progress of welding. The voltmeter 18 on the front side of the telescopic column 9 is used to monitor the voltage value output by the transformer 16 in real time. Through the voltmeter 18, the current working voltage can be clearly understood, so that corresponding adjustments can be made.

[0047] Working principle: A welding groove 3 is installed on the inner wall of the workbench 1 to accommodate the stamping parts to be welded. The feed groove 4 is designed on the left side of the workbench 1 to facilitate the introduction of the stamping parts and nuts into the welding groove 3. After the stamping parts and nuts enter the welding groove 3 through the feed groove 4, the push rod 5 drives the push plate 6 to move forward and accurately push the stamping parts to the center position of the welding groove 3. The nuts are manually placed at the position where the stamping parts need to be welded. The conductive plate 10 is connected to the pressurized support plate 8 through the telescopic column 9, and the rotating discharge plate 7 not only supports and guides the welded parts, but also forms an electrical connection with the conductive plate 10, becoming a loop part of the welding current. When the push plate 6 pushes the stamping parts to the center position of the welding groove 3, a current is generated between the conductive plate 10 and the rotating discharge plate 7. The high-intensity current generated passes through the stamping part and the nut, instantly generating high temperature to fuse the stamping part and the nut, thereby achieving the welding purpose. During the welding process, the rotating rod 11 and the support block 12 thereon provide a stable support and rotation basis for the rotating discharge plate 7, and the limit bar 13 ensures that the support block 12 is at a vertical angle to the rotating discharge plate 7, so as to ensure the position stability of the stamping part and the nut during the welding process. After the welding is completed, the rotating rod 11 is rotated to make the support block 12 lie flat. At this time, the top of the support block 12 no longer supports the rotating discharge plate 7, so that the rotating discharge plate 7 automatically rotates downward under its own weight, and the welded stamping part and nut fall into the cooling mechanism 2 by their own gravity for cooling, completing the entire automated welding process;

[0048] In addition, the connecting support column 201 firmly connects and supports the entire cooling mechanism 2 and the equipment body to ensure its stability during operation. A sufficient amount of coolant is added to the cooling pool 202 to absorb and take away the heat generated by the stamping parts during welding. The bracket carrier 203 serves as a support platform for the conveying motor 204. After the conveying motor 204 is started, it drives multiple transmission shafts 205 to rotate through its output end, thereby driving the transmission belt 206 on the outer wall of the transmission shaft 205 to circulate, ensuring that the stamping parts and nuts after welding are completed can move with the transmission belt 206. The front and rear ends of the middle transmission shaft 205 are also rotatably connected with bending wheels 207 for adjusting the transmission direction of the transmission belt 206, so that the left half of the transmission belt 206 ensures that the stamping parts and nuts can more effectively contact the coolant during the transmission process, while the right half can smoothly move the stamping parts and nuts out of the cooling pool 202.
