[0016] The utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. The following embodiments are only descriptive and are not limiting of the scope of protection of this utility model.

[0017] In its specific implementation, such as Figures 1-5 This utility model provides a technical solution: A multi-station nut welding machine includes a base plate 2, a welding body 1 on the top of the base plate 2, and the welding body 1 having multiple workstations, and further includes: Multiple welding modules 4 are installed at a workstation on one side of the welding body 1; The welding module 4 is equipped with a splash guard 5, which includes two protective rings 504. A sliding ring 506 is connected to the inner wall of each protective ring 504. A first spring 507 is connected to one side of the sliding ring 506, and a support ring 501 is connected to the other end of the first spring 507. The two first springs 507 apply force to the protective rings 504 to shield and protect the welding area. The welding module 4 is equipped with an upper welding rod and a lower welding rod, and the inner walls of the two support rings 501 are respectively connected to the outer walls of the upper and lower welding rods. The inner walls of the two sliding rings 506 are slidably connected to the outer walls of the upper and lower welding rods, respectively. Each inner wall of the two sliding rings 506 has two grooves 508, and a sliding strip 509 is slidably connected in the groove 508. Multiple sliding strips 509 are respectively connected to the outer walls of the upper and lower welding rods. The outer wall of the support ring 501 is connected to a fixed ring 502. A protective groove 505 is provided in the fixed ring 502. A protective cylinder 503 is slidably connected in the protective groove 505. One side of the protective cylinder 503 is connected to one side of the protective ring 504.

[0018] Specifically, by setting up the anti-splatter device 5, during welding, the transmission mechanism within the welding module 4 drives the welding rod downwards, causing the upper protective ring 504 to move. This allows the two protective rings 504 to contact the workpiece surface, causing the sliding ring 506 to move under the force of the two protective rings 504. The sliding ring 506 then compresses the first spring 507, causing the first spring 507 to generate a rebound force. This rebound force causes the sliding ring 506 to bring the protective rings 504 into close contact with the workpiece surface, ensuring that the two protective rings 504 shield the welding position and prevent welding sparks from splashing and injuring nearby operators. To ensure safety during welding, a groove 508 on the inner wall of the sliding ring 506 is provided to slide on the surface of the slide bar 509, allowing the slide bar 509 to support the sliding ring 506 and preventing the sliding ring 506 from shifting and getting stuck, thus affecting its movement. A protective ring 504 is provided to drive the protective cylinder 503 to slide in the protective groove 505, allowing the protective cylinder 503 and the fixed ring 502 to shield the first spring 507, preventing impurities from entering and adhering to the surface of the first spring 507 and affecting its contraction. Furthermore, by setting multiple workstations, the device can weld nuts of various sizes, thereby improving the ease of use and applicability of the device. A pedal 3 is connected to one side of the welding body 1 via an electric wire. A transmission plate is provided inside the pedal 3. A protective device 6 is provided on the inner wall of the pedal 3. The protective device 6 includes multiple support blocks 602. The support blocks 602 are embedded in the bottom of the pedal 3. A movable groove 603 is opened on the top of the support blocks 602. A movable block 601 is slidably connected in the movable groove 603. The top of the movable block 601 is in contact with the bottom of the transmission plate. A second spring 607 is connected to the bottom of the movable block 601. The other end of the second spring 607 is connected to the bottom of the movable groove 603. Limiting grooves 604 are opened on both sides of the inner wall of the movable groove 603. A limiting block 605 is slidably connected in the limiting groove 604. One side of the limiting block 605 is connected to one side of the movable block 601. A fixing groove is opened at the bottom of the movable block 601. A fixing rod 606 is slidably connected in the fixing groove. The bottom of the fixing rod 606 is connected to the bottom of the inner wall of the movable groove 603. The second spring 607 is sleeved on the outside of the fixing rod 606. Specifically, by setting up the protective device 6, when the operator steps on the pedal 3, the transmission plate on the inner wall of the pedal 3 presses against the movable block 601, causing the movable block 601 to move downward and press against the second spring 607. This causes the second spring 607 to generate a rebound force. By setting up the fixing rod 606 to support the second spring 607, the second spring 607 bends during compression, affecting its rebound effect. When the transmission plate inside the pedal 3 is released and reset, the movable block 601 resets due to the rebound of the second spring 607. This ensures that the top of the movable block 601 is always in contact with the bottom of the transmission plate, thus protecting the bottom of the transmission plate and preventing impurities from entering and affecting the movement of the transmission plate inside the pedal 3. By setting up the limiting block 605 to slide within the limiting groove 604, the unstable movement of the movable block 601 is prevented, thereby improving the protective effect of the movable block 601.

[0019] Working principle: The nut is placed on top of the lower welding rod, and then the workpiece is placed on top of the nut. Subsequently, the transmission mechanism in the welding module 4 drives the upper welding rod to move downward, causing the upper welding rod to move the protective ring 504 downward. The upper and lower protective rings 504 shield the welding area, preventing sparks generated during welding from flying out and injuring the operator. During welding, the operator steps on the transmission plate in the pedal 3, causing the transmission plate to move downward. The transmission plate presses the movable block 601, which in turn presses the second spring 607. The second spring 607 generates a rebound force. After the transmission plate is released, the movable block 601 is reset by the rebound force of the second spring 607, so that the top of the movable block 601 is always in contact with the bottom of the transmission plate. This protects the bottom of the transmission plate from falling nuts entering the bottom of the transmission plate and affecting its movement.

[0020] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
