[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0020] In this embodiment, as Figures 1 to 5 As shown, an automatic welding equipment workbench includes a frame 1 and an automatic welding equipment workbench surface 2 fixed on the frame 1. The automatic welding equipment workbench surface 2 is provided with a workpiece fixing mechanism for fixing the workpiece to be welded. The automatic welding equipment workbench surface 2 is also provided with an inner arc-shielding mechanism and an outer arc-shielding mechanism. The outer arc-shielding mechanism is located outside the inner arc-shielding mechanism, and there is a gap between the two. A lifting mechanism for raising and lowering the outer arc-shielding mechanism is provided outside the frame 1. The inner and outer arc-shielding mechanisms are used to close three sides of the automatic welding equipment workbench surface 2, and the remaining side forms an opening. The workpiece fixing mechanism is located at the opening.

[0021] In this embodiment, the automatic welding equipment workbench consists of a frame and an automatic welding equipment workbench surface fixed on the frame. A workpiece fixing mechanism is used to fix the workpiece to be welded. An inner and outer arc-shielding mechanism are installed on the automatic welding equipment workbench surface, enclosing three sides of the workbench surface and leaving one open side for placing the workpiece, thus blocking the welding arc light. The outer arc-shielding mechanism can also be raised and lowered via a lifting mechanism, allowing the blocking range to be adjusted. This workbench can be used for laboratory welding experiments or for manual welding stations in factories. This automatic welding equipment workbench can weld both round pipes and flat parts (i.e., by fixing fixtures on the welding table, splicing welds, flat welds, and vertical welds can be welded). To block the arc light during welding, the outer arc-shielding device can be raised directly to prevent arc light from injuring other personnel or equipment. If multiple people want to observe the welding effect at an exhibition or after welding, the outer arc-shielding mechanism can be lowered directly.

[0022] By incorporating an arc-shielding mechanism, the harm caused to operators by welding arc light can be effectively reduced, improving the safety of the working environment. Meanwhile, the design, with three sides enclosed and one side open, facilitates the placement and handling of workpieces.

[0023] In one or more embodiments of this utility model, the inner arc-shielding mechanism and the outer arc-shielding mechanism have the same structure. They are respectively formed by fixing a first enclosure frame 3 and a second enclosure frame 4 with a number of aluminum profiles. The first enclosure frame 3 is fixed to the worktable 2 of the automatic welding equipment by a number of fixing blocks 5. The second enclosure frame 4 is placed on the worktable 2 of the automatic welding equipment, and the output end of the lifting mechanism is fixed to the outside of the second enclosure frame 4.

[0024] In this embodiment, plates for blocking arc light are fixed inside the first enclosure frame 3 and the second enclosure frame 4; the enclosure frame is made of aluminum profile, which is lightweight and easy to install and operate. There is a gap between the two arc light blocking mechanisms, so that it does not affect the raising and lowering of the second enclosure frame 4. The second enclosure frame 4 can be raised and lowered as needed, improving the flexibility of the workbench.

[0025] In one or more embodiments of this utility model, the lifting mechanism includes a first mounting plate 6 and a second mounting plate 7 respectively fixed to the outer side of the frame 1. A reducer 8 is fixed to the outer side of the first mounting plate 6. A first gear is fixed to the outer output end of the reducer 8. A worm 9 is fixed to the inner output end of the reducer 8 through a coupling. The other end of the worm 9 passes through the frame 1 and the second mounting plate 7 and is fixed to a second gear 10. A fixing plate 11 is fixed to the outer side of both the first mounting plate 6 and the second mounting plate 7. A slider 12 is fixed to the outer side of the fixing plate 11. A lifting guide rail 13 is slidably arranged on the outer side of the slider 12. A lifting plate 14 is fixed to the outer side of the lifting guide rail 13. A rack 15 is also fixed to the inner side of the lifting plate 14. The first gear and the second gear 10 mesh with the corresponding rack 15. Two opposing connecting plates 16 are fixed to the outer side of the outer arc-shielding mechanism. The upper side of the lifting guide rail 13 is fixed to the outer surface of the connecting plate 16. A handwheel 20 is fixed to the output end of the reducer 8.

[0026] In this embodiment, the lifting mechanism mainly consists of a reducer, gears, a worm gear, a rack, a slider, a lifting guide rail, and a lifting plate. The first gear at the outer output end of the reducer meshes with the rack on the inner side of the lifting plate. The inner output end drives the worm gear to rotate via a coupling, and the second gear at the other end of the worm gear also meshes with the corresponding rack. Rotating the handwheel drives the reducer, causing the gears to rotate and moving the rack, lifting plate, and lifting guide rail up and down. The outer arc-blocking mechanism is connected to the lifting guide rail via a connecting plate, thus achieving lifting. Lifting is achieved through gear and rack transmission, resulting in smooth transmission and high precision. The handwheel is easy to operate, and the height of the outer arc-blocking mechanism can be adjusted according to actual needs.

[0027] Once the outer arc-blocking mechanism rises to the desired position, it does not need to be locked; it will not automatically descend. This method fully utilizes the self-locking function of the reducer. If the outer arc-blocking mechanism needs to descend, the handwheel must be turned to lower it. Using a handwheel instead of a motor or other drive method is more convenient than other methods, requires no external power or air supply, and is easy to move.

[0028] In one or more embodiments of this utility model, two oppositely arranged mounting seats 17 are fixed on the outer side of the frame 1, and a fixing seat 18 is fixed on the outer side of the first mounting plate 6 and the second mounting plate 7. A cover 19 is fixed on the mounting seat 17 and the fixing seat 18, and the cover 19 covers the outer side of the lifting guide rail 13, the lifting plate 14, the first gear and the second gear 10.

[0029] In this embodiment, the cover can protect the lifting mechanism, prevent dust and debris from entering, and improve the reliability and service life of the mechanism.

[0030] In one or more embodiments of this utility model, the workpiece fixing mechanism includes a support base 21 fixed on the worktable 2 of the automatic welding equipment, a support shaft 22 vertically fixed on the support base by bearings, a workpiece support base 23 slidably disposed on the support shaft 22, and the support shaft 22 and the workpiece support base 23 are fixed together by a pin 24.

[0031] In this embodiment, the two round tubes can be directly welded after being fixed to the workpiece support 23 with a fixing plate. The height of the workpiece support 23 can be adjusted up and down as needed, because the support shaft has holes in the vertical direction, which can be fixed by the pin 24. The support shaft 22 can also be rotated on the support, and can be locked by the locking screw on the support when rotated to the required angle.

[0032] In one or more embodiments of this utility model, four support legs 25 arranged in a rectangular array are fixed on the lower side of the frame 1.

[0033] In this embodiment, the support feet 25 are provided to ensure the stability of the automatic welding equipment worktable, prevent shaking during operation, and improve welding quality and safety.

[0034] Working principle of this utility model:

[0035] During welding, the workpiece to be welded is fixed by a workpiece fixing mechanism. The support shaft on the support base of this mechanism can rotate and move up and down, and the workpiece support base can slide on the support shaft and be fixed by a pin, facilitating the adjustment of the workpiece position and angle. During welding, the inner and outer arc-shielding mechanisms enclose three sides of the worktable to block arc light. The outer arc-shielding mechanism can be adjusted by lifting. When the reducer of the lifting mechanism is working, the first gear at its outer output end meshes with the rack on the inner side of the lifting plate. The inner output end drives the worm to rotate through a coupling, and the second gear at the other end of the worm also meshes with the corresponding rack, thereby driving the rack, lifting plate, and lifting guide rail to move up and down. The outer arc-shielding mechanism is connected to the lifting guide rail through a connecting plate to achieve lifting. The whole process can effectively fix the workpiece for welding and flexibly adjust the arc-shielding mechanism to adapt to different working scenarios and needs.
