Description

Technical Field

[0001] The utility model relates to the technical field of electromechanical automation, in particular to an electromechanical automation welding device. Background Art

[0002] Electromechanical automated welding combines mechanical, electrical, and automation technologies to automate the welding process. Through advanced control systems, sensors, and actuators, it precisely controls welding parameters and trajectories, improving welding quality and efficiency while reducing labor intensity and the impact of human factors on welding quality.

[0003] Under existing conditions, a welding fixture for electromechanical automation disclosed in announcement number CN220480704U is often used. The welding fixture is convenient for clamping two groups of plates and positioning them in an L-shaped state, which is convenient for subsequent welding of the two groups of plates, thereby improving the convenience and efficiency of welding operations, and being able to fix plates of different sizes and thicknesses, thereby enhancing the scope of application of the device. However, although it is capable of fixing parts to be welded of different types and specifications with independent clamping structures and driving structures, it is difficult to adjust their states, especially since existing welding operations are not spot welding, but line welding and surface welding are achieved through spot welding, so the position and state can only be adjusted by repeatedly disassembling and assembling the parts to be welded. This not only increases the labor intensity, but also cannot ensure that the parts to be welded can always be accurately docked, and thus the welding processing quality cannot be guaranteed.

DETAILED DESCRIPTION

[0023] 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 the embodiments.

[0024] Reference Figure 1-Figure 5 , an electromechanical automatic welding device, including a body 1, specifically referring to the specification Figure 1 With attached Figure 2 The body 1 is composed of a platform 101, an extension bracket 102 and a supporting bracket 103. The platform 101 is arranged horizontally, the extension bracket 102 is integrally connected to the lower end of the platform 101, and the supporting bracket 103 is symmetrically connected to the left and right ends of the platform 101, so that the body 1 as a whole is an H-shaped structure.

[0025] The body 1 is provided with a traction mechanism for pulling two parts to be welded toward each other for docking through the extension bracket 102 and the supporting bracket 103. Figure 1 -Attached Figure 3 The traction mechanism includes a driving worm 2 rotatably mounted on the platform 101. By arranging a driver on the platform 101, the rotational movement of the driving worm 2 can be realized, and a driven shaft 3 located on the left and right sides of the driving worm 2 is rotatably mounted in the extension bracket 102. A driven worm wheel 4 meshing with the driving worm 2 is key-connected to the driven shaft 3. A limited long hole 5 is jointly provided in the platform 101 and the supporting bracket 103. A traction rod 6 is fixedly mounted on the driven shaft 3 and passes through the limited long hole 5. Under the driving action of the worm 2, the two traction rods 6 are deflected toward or in opposite directions. The sliding sleeve in the supporting bracket 103 is equipped with a right-angle movable frame 7 that is movably pulled by the traction rod 6. The right-angle movable frame 7 is rotatably installed with a load-bearing shaft 8 with a fixed connection limit mechanism. It should be noted that by arranging a driver on the right-angle movable frame 7, the load-bearing shaft 8 can be driven to rotate, thereby driving the workpiece to be welded to rotate, so that the welder 21 can perform 360° circumferential spot welding on the welding part of the workpiece to be welded.

[0026] The supporting bracket 103 is provided with a limiting mechanism for fixing the parts to be welded through a traction mechanism. Figure 3 With attached Figure 4 The limiting mechanism includes a load-bearing carrier 9 fixedly connected to the load-bearing rotating shaft 8. When it is necessary to weld the T-shaped parts to be welded, the two are first fitted together, and then the welding parts of the two are butted together. A central notch 10 for fitting the end of the parts to be welded is provided at the center of the load-bearing carrier 9, and T-shaped three-way long holes 11 are provided on both sides of the load-bearing carrier 9. A first spring 12 is welded in the central notch 10, and an I-shaped booster 13 fixedly connected to the first spring 12 and used to resist the end of the parts to be welded is slidably fitted in the central notch 10. The openings at both ends of the T-shaped three-way long hole 11 are fitted with I-shaped boosters 13 fixed to the I-shaped boosters 13. The wedge driving rod 14 is connected, and a second spring 15 is welded to the middle opening position of the T-shaped three-way long hole 11. Under the elastic force of the first spring 12 and the second spring 15, the wedge limiting clamp 16 always has a tendency to shrink and reset into the T-shaped three-way long hole 11, and the middle opening position of the T-shaped three-way long hole 11 is slidingly sleeved with a wedge limiting clamp 16 fixedly connected to the second spring 15 and slidingly resisting the wedge driving rod 14 to clamp and fix the workpiece to be welded. The I-shaped booster 13 is pressurized by the workpiece to be welded, so that the symmetrically installed wedge limiting clamp 16 extends into the center notch 10 to fix the end of the workpiece to be welded.

[0027] Please refer to the instruction manual for details Figure 5The platform 101 is integrally provided with left-right guide rails 17 at the front and rear ends, and a movable truss 18 is slidably installed on the guide rail 17. A guide long hole 19 is vertically opened on one side of the movable truss 18, and a placement block 20 for movably placing the welding rod is slidably sleeved in the guide long hole 19. It should be noted that by adjusting the placement block 20 up and down, the welding rod can be adjusted in position according to the size of the welding part of the workpiece to be welded. A welder 21 for welding two workpieces to be welded by using a welding rod is movably provided on the movable truss 18. The welder 21 is horizontally displaced and vertically lifted and lowered along the movable truss 18 to perform spot welding operations on the workpiece to be welded.

[0028] A traction long hole 601 is provided in the free end of the traction rod 6, and a driven long bolt 701 is integrally connected to the right-angle movable frame 7 and is slidably mounted in the traction long hole 601. During the deflection process, the traction rod 6 drives the right-angle movable frame 7 to move telescopically in the horizontal direction through the driven long bolt 701 to adjust the horizontal position of the workpiece to be welded.

[0029] The T-shaped three-way long holes 11 are symmetrically distributed on both sides of the central notch 10, and the wedge head limiting clamping plate 16 slides and extends into the central notch 10 to clamp and fix the welded parts sleeved in the central notch 10.

[0030] It should be noted that the specific model and specifications of the welding device 21 need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it is not repeated here.

[0031] The functional principle of this utility model can be explained through the following operation modes:

[0032] Initially place the workpiece to be welded into the center notch 10 and control the drive worm 2 to rotate;

[0033] The driving worm 2 drives the driven rotating shaft 3 to deflect through the driven worm gear 4, causing the traction rod 6 to deflect synchronously, thereby driving the right-angle moving frame 7 to move horizontally on the supporting bracket 103. During the process of the two parts to be welded contacting each other, the I-shaped booster 13 is pressed, causing the wedge head driving rod 14 to move linearly and pressurize the wedge head limiting clamp 16 until the wedge head limiting clamp 16 extends into the center notch 10 and clamps the parts to be welded;

[0034] The load-bearing shaft 8 drives the welded parts to flip over;

[0035] The movable truss 18 is moved by the guide rail 17 , and welding rods corresponding to the contacting positions of the two parts to be welded are set in the placement block 20 , and the welding rods and the parts to be welded are spot-welded by the welder 21 .

[0036] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
