[0022] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0023] like Figures 1 to 4As shown, an engine compartment side beam welding device includes an operating table 1. An electric rotary platform 2 is fixedly installed on the upper side of the operating table 1. A robotic arm 3 is fixedly installed on the upper end of the electric rotary platform 2. An installation assembly 4 is fixedly installed at the end of the robotic arm 3. The installation assembly 4 includes a fixed shaft 401, which is fixedly installed at the end of the robotic arm 3. A control motor 402 is fixedly installed at the lower end of the fixed shaft 401. A mounting base 403 is fixedly installed at the output end of the control motor 402. A cleaning assembly 6 for cleaning the workpiece surface and an electric welding assembly 5 for welding the side beam are respectively installed on both sides of the mounting base 403. A PLC controller 7 is fixedly installed on one side of the operating table 1. The electric rotary platform 2, the robotic arm 3, and the control motor 402 are all connected to the PLC controller 7 via signals.

[0024] The PLC controller 7 can precisely control the rotation angle of the electric rotary platform 2 and the swing angle of each joint of the robotic arm 3, so that the mounting component 4 can be aligned with the welding position, thereby realizing a comprehensive welding operation. The cleaning component 6 is integrated into the above structure to achieve a comprehensive cleaning treatment of the welding area, avoiding the presence of oxide scale, rust, oil and other impurities on the surface of the welding area due to uncleaning and grinding during welding, which would interfere with the subsequent welding quality. Therefore, this application can enhance the strength of welding, eliminating the need for operators to manually clean the workpiece before welding, optimizing the workflow and improving welding efficiency. The position of the cleaning component 6 and the welding component 5 can be adjusted by starting the control motor 402, and the control motor 402 rotates in the opposite direction to reset, avoiding wire tangling.

[0025] In this embodiment, the mounting base 403 has a combination groove 404 on both sides, a combination plate 406 is inserted inside the combination groove 404, and a mounting plate 407 is fixedly installed on the outside of the combination plate 406.

[0026] Among them, a locking bolt 405 is provided on the outside of the combination groove 404, and the locking bolt 405 passes through the combination groove 404 and is threadedly engaged with the adjacent combination plate 406.

[0027] The connection between the combination groove 404 and the combination plate 406 is locked by the locking bolt 405, so that the cleaning component 6 and the welding component 5 can be installed as needed, and it is also convenient to disassemble and maintain the cleaning component 6 and the welding component 5 later.

[0028] In this embodiment, the welding assembly 5 includes a welding machine 501, which is fixedly mounted on the upper surface of the operating table 1. A welding gun 503 is electrically connected to the interface of the welding machine 501 via a cable 502. The welding machine 501 is signal-connected to the PLC controller 7, and the welding gun 503 is fixedly mounted inside one of the mounting plates 407. By starting the welding machine 501, the welding gun 503 can perform welding on the area it passes through, under the action of the cable 502.

[0029] In this embodiment, the cleaning component 6 includes a sand storage tank 601, which is fixedly installed on one side of the operating table 1. A sandblasting pump 602 is installed at the discharge port of the sand storage tank 601, and a sandblasting hose 603 is installed at the discharge port of the sandblasting pump 602. A sandblasting head 604 is fixedly installed at one end of the sandblasting hose 603. The sandblasting head 604 is fixedly installed inside one of the mounting plates 407. An expansion plate 6042 is provided at the bottom of the sandblasting head 604. A plurality of shielding brushes 6043 are provided on the lower surface of the expansion plate 6042. The shielding brushes 6043 are arranged in a ring to surround the bottom of the sandblasting head 604.

[0030] The sandblasting head 604 has a sandblasting cavity 6041 inside. The upper end of the sandblasting cavity 6041 is provided with a sand inlet 6045, which is connected to the sandblasting hose 603. A sand discharge port 6044 is provided on one side of the sandblasting cavity 6041.

[0031] By activating the sandblasting pump 602, the cleaning sand inside the sand storage tank 601 can be transported to the sandblasting hose 603. Under the action of the sandblasting hose 603, the sandblasting hose 603 is sprayed out from the sand inlet 6045 to sandblast and clean the workpiece at the current position. During the cleaning process, several shielding brushes 6043 can not only adapt to the surface of the workpiece, but also prevent the cleaning sand and impurities from spreading outward. During this process, by activating the sand return fan 606, the sand discharge port 6044 will continuously extract the cleaning sand and the cleaned impurities. Through the above structure, the welded joint of the edge beam can be cleaned stably, and the cleaning sand and impurities can be recovered during the cleaning process, which is beneficial to personnel management.

[0032] It should be noted that the masking brush 6043 is made of heat-resistant material, and its distribution density is smaller than the diameter of the cleaning abrasive to prevent the cleaning abrasive from spreading outwards and to avoid generating heat during the cleaning process that could affect the performance of the masking brush 6043.

[0033] In this embodiment, a sand return fan 606 is fixedly installed on one side of the operating table 1. A sand return hose 607 is installed at the sand inlet end of the sand return fan 606. The sand return hose 607 is connected to the sand discharge port 6044. A conveying pipe 608 is installed at the sand outlet end of the sand return fan 606.

[0034] Among them, a small cyclone separator 605 is fixedly installed at the upper end of the inlet of the sand storage tank 601. The inlet of the small cyclone separator 605 is connected to the conveying pipe 608, the sand discharge end of the small cyclone separator 605 is connected to the inlet of the sand storage tank 601, and a waste outlet is provided on one side of the small cyclone separator 605.

[0035] Impurities and clean sand can be transferred from the return sand hose 607 to the conveying pipe 608 by the return sand blower 606, and then enter the small cyclone separator 605. The small cyclone separator 605 separates the impurities and clean sand. The small cyclone separator 605 can be equipped with a corresponding model and size as needed. The separated waste is discharged from the waste outlet, and the clean sand is stored again in the sand storage tank 601 to reduce the waste of clean sand.

[0036] The sand return fan 606 ensures that the cleaning sand will not remain in the sandblasting cavity 6041 after cleaning. Under the action of the sand return fan 606, the cleaning sand will continue to flow and no sand particles will remain.

[0037] The working principle of this type of engine compartment side beam welding equipment:

[0038] In use, the engine compartment side beam is first fixed with a fixing fixture. Then, the rotation angle of the electric rotary platform 2 and the swing angle of each joint of the robotic arm 3 can be precisely controlled by the PLC controller 7, so that the installation component 4 is close to the welding part of the side beam.

[0039] Subsequently, by starting the welding machine 501 and using the cable 502, the welding gun 503 can perform welding on the area it passes through.

[0040] During the welding process, the sandblasting pump 602 can be started to deliver the cleaning sand inside the sand storage tank 601 to the sandblasting hose 603. Under the action of the sandblasting hose 603, the sandblasting hose 603 is sprayed out from the sand inlet 6045 to clean the workpiece at the current position. During the cleaning process, the shielding brushes 6043 can not only adapt to the surface of the workpiece, but also prevent the cleaning sand and impurities from spreading outward during the cleaning process.

[0041] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
