It should be understood that the specific embodiments described herein are merely illustrative of this disclosure and are not intended to limit it.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as a limitation of this utility model.

[0021] Please refer to Figures 1-6As shown, this application discloses an automatic welding device, including a fixed base 1. The fixed base 1 has a clamping mechanism 3, a first guide rail, and a second guide rail. The first guide rail and the second guide rail are arranged in parallel. A welding mechanism 2 is arranged on the first guide rail. A lifting mechanism 4 and a concentric positioning mechanism 5 are arranged sequentially on the second guide rail. The first guide rail and the second guide rail are preferably high-precision linear guide rails. The welding mechanism 2 is slidably connected to the first guide rail and is used to perform welding operations. The clamping mechanism 3 is located at one end of the second guide rail and is used to clamp the workpiece to be welded. The lifting mechanism 4 and the concentric positioning mechanism 5 are both slidably connected to the second guide rail. The lifting mechanism 4 is located between the clamping mechanism 3 and the concentric positioning mechanism 5 and is used to lift the workpiece to be welded. The welding mechanism 2 includes a column 6 and a welding head mechanism 13 mounted on the column 6. The column 6 is slidably mounted on a first guide rail. The welding head mechanism 13 includes a mounting frame 16, a welding torch 17, and an adjustment mechanism. The mounting frame 16 is connected to the adjustment mechanism. The welding torch 17 is mounted on the mounting frame 16. The adjustment mechanism is used to drive the mounting frame 16 to produce displacement changes. The position and posture of the welding torch 17 can be finely adjusted through the adjustment mechanism, which further ensures the accurate alignment of the welding torch 17 relative to the weld, thereby improving the welding quality and product consistency. In this application, the welding mechanism 2 slides independently along the first guide rail, while the lifting mechanism 4 and the concentric positioning mechanism 5 slide along the second guide rail. This layout allows the equipment to flexibly adapt to workpieces of different sizes and shapes. By adjusting the positions of each mechanism, the welding requirements of various workpieces can be met, demonstrating strong versatility. Through the coordinated action of the clamping mechanism 3, the lifting mechanism 4, and the concentric positioning mechanism 5, precise positioning, stable support, and centering of the workpieces can be achieved, effectively avoiding misalignment and deformation during the welding process. Furthermore, this layout effectively reduces the clamping and turnover time of the workpieces, significantly improving the overall efficiency of welding production.

[0022] The column 6 serves as the supporting body for the welding head mechanism 13. It includes a base plate and a column mounted on the base plate, with the base plate and column connected by bolts. The base plate is slidably mounted on a first guide rail. For automated control, a first driving component 15 is connected to the base plate. The first driving component 15 drives the base plate to slide along the first guide rail. Specifically, the first driving component 15 is a stepper motor, which drives the base plate and the entire column on it to reciprocate stably along the extension direction of the first guide rail. A crossbeam 14 and a displacement mechanism are provided on the column 6. The displacement mechanism includes a second driving component and a third driving component 33, which are respectively driven and connected to the crossbeam 14. The second driving component drives the crossbeam 14 to reciprocate along the axial direction of the column 6, and the third driving component 33 drives the crossbeam 14 to reciprocate horizontally. Specifically, the second driving component is a motor, and the third driving component 33 is a screw assembly. The second driving component provides the welding torch 17 with a large stroke in the vertical direction, and the third driving component 33 provides a wide range of movement in the horizontal direction. The welding head mechanism 13 is spatially positioned in three directions: X (the extension direction of the first guide rail), Y (the axial direction of the crossbeam 14 along the column 6), and Z (the horizontal direction of the crossbeam 14) by means of the first driving member 15, the second driving member, and the third driving member 33.

[0023] The adjustment mechanism includes a longitudinal adjustment mechanism 7, a lateral adjustment mechanism 8, and a rotation mechanism 9. The mounting bracket 16 is connected to the longitudinal adjustment mechanism 7 through a first sliding component. The longitudinal adjustment mechanism 7 is connected to the lateral adjustment mechanism 8 through a second sliding component. The lateral adjustment mechanism 8 is connected to the rotation mechanism 9 through a connector. The rotation mechanism 9 is located on the crossbeam 14.

[0024] Please refer to Figure 6 and Figure 7 As shown, the longitudinal adjustment mechanism 7 further includes a first housing 18 and a first stepper motor. The output shaft of the first stepper motor is at least partially located within the first housing 18, and a first sliding assembly is connected to the output shaft of the first stepper motor. By placing the output shaft of the first stepper motor within the first housing 18 and connecting it to the first sliding assembly, the power transmission is internalized, making the structure more compact. Simultaneously, the first housing 18 provides good dust protection for the transmission components, improving their service life. The first sliding assembly includes a rib 19 and a first slider. The first slider includes a first connecting portion and a second connecting portion. The first connecting portion is located within the first housing 18 and has a through hole for the output shaft of the first stepper motor to pass through. The side of the second connecting portion away from the first connecting portion extends outside the first housing 18. One side of the rib 19 is connected to the second connecting portion, and the other side of the rib 19 is connected to the mounting bracket 16. The rib 19 enhances the bending and torsional stiffness between the first stepper motor and the welding torch 17, effectively suppressing vibration or deformation caused by the force on the welding torch 17, and ensuring the quality of the weld formation.

[0025] Furthermore, the lateral adjustment mechanism 8 includes a second housing and a second stepper motor. The output shaft of the second stepper motor is at least partially located within the second housing, and the second sliding assembly is connected to the output shaft of the second stepper motor. Specifically, the second sliding assembly includes a second slider, which includes a third connecting portion and a fourth connecting portion. The third connecting portion is located within the second housing and has a through hole for the output shaft of the second stepper motor to pass through. The fourth connecting portion extends out of the second housing on the side away from the third connecting portion and is connected to the first housing 18 by bolts. It can be understood that the second slider, through its fourth connecting portion, drives the first housing 18 and all its components (including the mounting bracket 16 and the welding torch 17) to reciprocate laterally, thereby achieving lateral circumferential welding.

[0026] like Figure 8 As shown, the rotating mechanism 9 further includes a main body 10, a rotating part 11, and an operating part 12. The rotating part 11 is rotatably mounted on the main body 10, and the operating part 12 is drively connected to the rotating part 11 to drive the rotating part 11 to rotate. The connecting part is a connecting flange, and the second housing is connected to the rotating part 11 through the connecting flange. The second housing and the connecting flange rotate synchronously with the rotating part 11. The operating part 12 is a crank, with one end connected to the rotating part 11 and the other end having a handle. The operator rotates the operating part 12 by holding and rotating the handle, thereby driving the rotating part 11 to rotate. This allows for fine adjustment of the welding angle of the welding torch 17, enhancing the equipment's flexibility and adaptability to different welding processes. The manual crank mechanism eliminates the need for a drive motor (such as a servo motor), corresponding sensors, and complex control circuits for this degree of rotational freedom, simplifying the structure and reducing the equipment's manufacturing and maintenance costs.

[0027] In this application, the longitudinal movement, lateral movement, and rotation of the welding torch 17 are independently controlled, avoiding the complexity of connecting multiple components and the need for complex algorithms to decouple the motion trajectory, thus reducing the difficulty and cost of the control system. Since the movements of the welding torch 17 are independent, damaged components can be replaced or repaired individually, reducing maintenance difficulty and costs. Through the combination of the longitudinal adjustment mechanism 7, the lateral adjustment mechanism 8, and the rotation mechanism 9, precise control of the position and attitude of the welding torch 17 with multiple degrees of freedom can be achieved.

[0028] Please continue reading. Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, in one embodiment of this application, the clamping mechanism 3 includes a base 20 and a clamping member disposed on the base 20. The base 20 is mounted on the fixed base 1 by bolts or other equivalent means and is located at one end of the second guide rail. The clamping member is used to clamp the workpiece to be welded. Specifically, the clamping member includes a mounting base 21, a turntable 22, and three grippers 23. The mounting base 21 is rotatably connected to the base 20, and the turntable 22 is rotatably connected to the mounting base 21 via bearings. The three grippers 23 are evenly spaced along the circumference of the turntable 22. The mounting base 21 is connected to a fourth driving member 24 for driving its rotation, and the turntable 22 is connected to a fifth driving member 25 for driving its rotation. The fourth driving member 24 is a manual crank, and the fifth driving member 25 is a servo motor. More specifically, the base 20 includes two vertical plates 32, forming an installation space between them. The base 20 is at least partially located within this installation space. Rotating shafts 31 are coaxially arranged on both sides of the mounting base 21, and these shafts 31 are parallel to the fixed base 1. The two rotating shafts 31 are rotatably connected to the two vertical plates 32 respectively. A fourth driving member 24 is connected to one of the rotating shafts 31 and drives the rotating shaft 31 to rotate, thereby causing the mounting base 21 to rotate. The fourth driving member 24 can be used to drive the mounting base 21 to rotate 0-90 degrees, allowing the welding equipment to adapt to more welding processes and parts to be welded. Since the turntable 22 is mounted on the mounting base 21, the turntable 22 rotates synchronously with the mounting base 21. Three grippers 23 are evenly spaced along the circumference of the turntable 22 and can be pneumatically or hydraulically driven to achieve synchronous opening and closing movements, precisely gripping or releasing the parts to be welded.

[0029] like Figure 2 and Figure 3 As shown, the lifting mechanism 4 provides support and lifting force from below the workpiece to be welded. It is slidably connected to the second guide rail to accommodate workpieces of different lengths. The lifting mechanism 4 includes a support base 26 and a lifting part disposed on the support base 26. The bottom of the support base 26 slides in engagement with the second guide rail. A first locking component can be provided between the support base 26 and the second guide rail to lock its position (when the support base 26 slides along the second guide rail to an appropriate position, its position is locked by the first locking component). The support base 26 may also be connected to a motor for driving it to slide along the second guide rail.

[0030] Furthermore, the lifting section includes a third housing 27 and a bracket 28. The third housing 27 is mounted on the support base 26, and the bracket 28 is at least partially housed within the third housing 27. The bracket 28 is connected to a lifting assembly 36, which drives the bracket 28 to move up and down relative to the third housing 27, thereby accommodating welded parts of different diameters and lifting them to a predetermined height. Specifically, the lifting assembly 36 is an electric push rod, a hydraulic cylinder, a hand-cranked screw jack, or a manual ball screw vertical lifting mechanism.

[0031] To better accommodate the size and shape of the parts to be welded, the bracket 28 is provided with several adjustable slots 29 spaced apart. Each adjustable slot 29 is an open slot. The bracket 28 also has two roller assemblies 30, each comprising a connecting shaft and a wheel mounted on the connecting shaft. The two ends of the connecting shaft overlap within the adjustable slots 29. By selecting different adjustable slots 29, the distance between the two roller assemblies 30 can be adjusted, thereby supporting parts of different sizes to be welded.

[0032] like Figure 2 and Figure 4 As shown, the concentric positioning mechanism 5 includes a sliding seat 34 and a positioning component 35 disposed on the sliding seat 34. The sliding seat 34 can slide manually or via a drive mechanism on the second guide rail. The positioning component 35 includes a telescopic ejector pin and a drive cylinder. The drive cylinder includes a cylinder body and a piston disposed within the cylinder body. The telescopic ejector pin is drivenly connected to the piston. When the cylinder actuates, it pushes the telescopic ejector pin forward, pressing it against the center hole at the end of the workpiece to be welded. This, in conjunction with the clamping mechanism 3, ensures that the workpiece is on an accurate rotational centerline, guaranteeing the concentricity requirements of the welding process.

[0033] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The descriptions of the embodiments above are only for the purpose of helping to understand the present application and its core ideas. It should be noted that those skilled in the art can make several improvements and modifications to the present application without departing from the principles of the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
