[0002] At present, with the development of industrialization and informatization, various mechanical equipment have gradually replaced manual labor in various industries. Mechanical equipment has the characteristics of high precision and high intelligence, which can greatly improve work efficiency.

[0003] Mechanical equipment is generally assembled from a variety of parts, and the parts need to be welded by welding equipment during processing and production. When welding, the existing welding equipment generally clamps the parts with a clamping mechanism, and then welds them with a welding gun. However, during the welding process, the welding part is affected by high temperature and produces harmful gases such as smoke. The harmful gases are generally adsorbed by the exhaust gas treatment mechanism set around the welding equipment. Since the exhaust gas treatment equipment is far away from the welding part of the parts, the harmful gases will diffuse into the surrounding air before being adsorbed by the exhaust gas treatment equipment, so that the exhaust gas treatment equipment cannot fully remove the exhaust gas. The workers are prone to inhaling some harmful gases, which affects the health of the workers. Moreover, after the welding is completed, the welding gun is generally directly exposed to the external environment, which makes the welding gun easily damaged by collision with foreign objects, and the protection effect is poor. To this end, we propose a welding equipment for processing mechanical equipment parts. Utility Model Content

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] Reference Figure 1-Figure 4 A welding device for machining parts of mechanical equipment includes a base 1, a U-shaped frame 5 is installed on the top of the base 1, a control box 11 is installed on the side of the U-shaped frame 5, a six-axis manipulator 3 is installed on one side of the top of the base 1, a welding gun 18 is installed at the end of the six-axis manipulator 3, and the six-axis manipulator 3 is connected to a controller in the control box 11 through a wire. During use, the position of the welding gun 18 can be adjusted by the six-axis manipulator 3, so that the welding gun 18 is aligned with the welding part of the part, and the part is welded.

[0028] like Figure 1As shown, an operating table 8 is installed at the other end of the top of the base 1 through a plurality of supporting rods 9, and a storage plate 7 is rotatably connected to the top of the operating table 8. The top of the storage plate 7 extends below the operating table 8 and is connected to a drive motor 10. The drive motor 10 is a brake motor, which is fixed to the bottom of the operating table 8 and connected to the controller through a wire. The staff can place the parts to be welded on the storage plate 7, so that when welding, the drive motor 10 can drive the storage plate 7 to rotate, so that the workpiece can be rotated to a specific angle as needed.

[0029] like Figure 1 As shown, a pressing plate 6 is provided inside the U-shaped frame 5, and the pressing plate 6 is located below the storage plate 7, and the top of the pressing plate 6 is rotatably connected to a telescopic mechanism 4, which is fixed on the U-shaped frame 5, and the telescopic mechanism 4 is connected to a controller inside the control box 11 through a wire, and the telescopic mechanism 4 is a hydraulic rod or an electric push rod. In actual use, the controller can control the telescopic mechanism 4 to extend, push the pressing plate 6 down, and press and fix the parts placed on the storage plate 7 to prevent the parts from shaking during welding, and the pressing plate 6 is fixed to the telescopic mechanism 4 through a bearing, so that during the welding process, the pressing plate 6 can rotate with the parts;

[0030] like Figure 1 and Figure 2 As shown, legs 17 are installed at the four corners of the bottom of the base 1, a horizontal plate 14 is installed between the legs 17, an air suction pump 12 is installed on one side of the top of the horizontal plate 14, the air suction pump 12 is connected to the controller through a wire, the air inlet end of the air suction pump 12 is fixed to the side of the adsorption box 15 through an air inlet pipe 13, the bottom of the adsorption box 15 is fixed on the horizontal plate 14, the top of the adsorption box 15 is provided with a box cover 16, the top of the box cover 16 is installed with an adsorption tube 2, the top of the adsorption tube 2 passes through the base 1, and the other end of the adsorption tube 2 is installed with an adsorption head 19, and the adsorption head 19 is fixed to the welding gun 18 through a fixing frame 22. During use, the adsorption tube 2 is a flexible metal hose, so that the adsorption tube 2 can move with the six-axis manipulator 3, and the adsorption head 19 can move with the welding gun 18. In this way, the suction pump 12 sucks out the air in the adsorption box 15 through the air inlet pipe 13, so that a negative pressure is generated in the adsorption box 15, and then suction is generated on the adsorption tube 2 and the adsorption head 19. The adsorption head 19 can suck the harmful gases generated during the welding process into the adsorption box 15 for treatment.

[0031] It should be noted that the end opening of the adsorption head 19 is set to be wide-mouthed, which can increase the adsorption performance of the adsorption head 19 and improve the adsorption effect.

[0032] like Figure 3As shown, a support frame 20 is installed on the inner side wall of the adsorption box 15, and an air filter 21 is arranged on the top of the support frame 20, and the upper and lower ends of the air filter 21 are respectively sealed with the support frame 20 and the box cover 16, and the air filter 21 is located between the adsorption tube 2 and the air intake pipe 13. The air filter 21 is supported by the support frame 20 shell so that the air filter 21 can be fixed in the adsorption box 15. In this way, during use, the harmful gas generated by welding can be transported to the adsorption box 15 through the adsorption head 19 and the adsorption tube 2, and the harmful gas can pass through the air filter 21. Under the action of the air filter 21, the harmful gas can be filtered clean, and the filtered clean air can be discharged into the external environment through the suction pump 12.

[0033] like Figure 4 As shown, a through slot 29 matching the end of the six-axis manipulator 3 is also provided on the top of the base 1, and a protective box 27 is installed at the bottom of the base 1. The top opening of the protective box 27 is connected to the through slot 29, and the welding gun 18 extends into the protective box 27. When welding is not needed, the welding gun 18 can be moved from the through slot 29 into the protective box 27, and the end of the six-axis manipulator 3 will cover the opening of the through slot 29 to cover the opening of the through slot 29, so that the welding gun 18 is located in a confined space and will not be damaged by collision with foreign objects.

[0034] It should be noted that a receiving groove 31 is opened at one end of the through groove 29. When the welding gun 18 is stored, the part of the welding gun 18 extending outside the end of the six-axis manipulator 3 can be moved from the receiving groove 31 into the protective box 27. In this way, when the welding gun 18 is stored, the welding gun 18 will not collide with the base 1.

[0035] like Figure 4 As shown, a U-shaped block 24 is installed on the side of the end of the six-axis manipulator 3, and the inside of the U-shaped block 24 is rotatably connected to a cover plate 26, which covers the receiving groove 31. When the welding gun 18 is moved into the protective box 27, the staff rotates the cover plate 26 to a horizontal position to cover the receiving groove 31, thereby improving the protection of the welding gun 18.

[0036] like Figure 2 As shown, a connecting plate 28 is installed on one side of the end of the six-axis manipulator 3 near the cover plate 26, and a pair of limit blocks 25 are symmetrically installed on the side of the connecting plate 28. When the cover plate 26 is rotated to a vertical position, the cover plate 26 is located between the limit blocks 25. The limit blocks 25 are made of elastic metal or elastic rubber. When welding is required, the staff only needs to rotate the cover plate 26 to a vertical position so that the cover plate 26 moves between the two limit blocks 25. The limit blocks 25 can clamp and fix the cover plate 26 to prevent the cover plate 26 from interfering with the welding.

[0037] It should be noted that if Figure 1As shown, an arc groove 30 is also opened on one side of the through groove 29, and the adsorption tube 2 is located in the arc groove 30. When the welding gun 18 is stored, the adsorption tube 2 can pass through the arc groove 30 and move into the protective box 27, so that the adsorption tube 2 will not be squeezed by the base 1 and damaged.

[0038] Specifically, when the utility model is in use, the staff places the parts to be welded on the storage plate 7, and then controls the telescopic mechanism 4 to extend, pushes the pressure plate 6 to move down, so that the pressure plate 6 is pressed on the top of the parts to fix the parts, and then controls the welding gun 18 through the six-axis manipulator 3 to aim at the part to be welded of the workpiece to perform welding. At the same time, the suction pump 12 is controlled to work, and the suction pump 12 sucks out the gas in the adsorption box 15, so that the adsorption tube 2 and the adsorption head 19 generate suction, and the harmful gas generated during the welding process is adsorbed into the adsorption box 15, and filtered through the air filter element 21, and finally the filtered clean air is transported from the intake pipe 13 to the suction pump 12 and then discharged into the external environment. After the welding is completed, the staff can control the six-axis manipulator 3 to move the welding gun 18 from the through slot 29 into the protective box 27 for storage.

[0039] Furthermore, if Figure 1 As shown, a plurality of limiting sleeves 23 are installed on the side of the six-axis manipulator 3, and each limiting sleeve 23 is slidably sleeved on the adsorption tube 2. The limiting sleeve 23 can limit the adsorption tube 2 so that the adsorption tube 2 will not be scattered on the base 1, so that the adsorption tube 2 will not hinder the welding.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
