[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] Reference Figure 1 、 Figure 2 、 Figure 4 The utility model provides an embodiment: an automated clamping welding device, comprising a base 1, a mobile component for facilitating all-round welding of a hydraulic cylinder fixedly connected to the top of the base 1, the mobile component enables the device to flexibly adjust its position and angle, thereby adapting to the welding needs of hydraulic cylinders of different shapes and sizes. A support block 5 is fixedly connected to the top of the mobile component, a fixed ring 6 is fixedly connected to the top of the support block 5, and a rotating gear ring 7 is rotatably connected to the inner wall of the fixed ring 6. The support block 5 is used to support the entire clamping mechanism, and the fixed ring 6 provides a stable motion support base for the rotation of the rotating gear ring 7. The outer wall of the rotating gear ring 7 is rotatably connected to a plurality of rotating columns 8, and the outer wall of the rotating column 8 is fixedly connected to a follower ring 9. As the rotating column 8 rotates, the follower ring 9 is driven to rotate, and the outer walls of the plurality of follower rings 9 are slidably connected to the outer wall of the rotating gear ring 7, thereby providing a stable rotation support point for the rotation of the follower ring 9.

[0036] The outer wall of the follower ring 9 is fixedly connected to a connecting rod 10. The other end of the connecting rod 10 is rotatably connected to a rotating shaft 11. Both ends of the rotating shaft 11 are fixedly connected to sliders 13. The rotation of the follower ring 9 drives the connecting rod 10 to move synchronously. The rotation of the rotating shaft 11 causes the slider 13 to move vertically as a result of the connecting rod 10's rotation. The outer wall of the rotating gear ring 7 is fixedly connected to multiple chute blocks 12. The outer wall of the slider 13 slides inside the chute blocks 12. The chute blocks 12 provide a motion track for the sliders 13 and limit their horizontal movement, forcing them to move only along the axial direction of the chute blocks 12. The other end of the slider 13 is fixedly connected to a clamp 14. The movement of the slider 13 causes the three clamps 14 to move together, clamping the hydraulic cylinder. The outer wall of the rotating gear ring 7 is fixedly connected to a drive assembly that drives the clamping mechanism to adaptively clamp the hydraulic cylinder.

[0037] The drive assembly includes an electric push rod 18, one end of which is fixedly connected to the outer wall of the rotating gear ring 7, thereby securing the push rod 18 and maintaining stability during operation. The output end of the push rod 18 is fixedly connected to a drive block 19, and the other end of the drive block 19 is fixedly connected to a drive rod 20. The drive rod 20 and the drive block 19 are used to transmit the power of the push rod 18 to subsequent components. A transmission assembly is fixedly connected to the outer wall of the rotating column 8, which transmits the power of the drive assembly.

[0038] The transmission assembly includes a second rotating shaft 15, the bottom of which is fixedly connected to the outer wall of the rotating column 8. The outer walls of two of the second rotating shafts 15 are fixedly connected to V-shaped rods 16, so that when the V-shaped rods 16 are subjected to force, they can drive the second rotating shaft 15 to move, thereby driving the rotating column 8 to rotate, thereby driving the clamp 14 to perform a clamping operation. The other end of the drive rod 20 is rotatably connected to one end of one of the V-shaped rods 16, so that the power of the drive assembly can be transmitted to the transmission assembly and, through the transmission assembly, to the clamping assembly. The adjacent ends of the two V-shaped rods 16 are rotatably connected to a transmission rod 17. The two ends of the other transmission rod 17 are rotatably connected to the other end of the rotating rod 27 and the other end of the top V-shaped rod 16, respectively. The outer wall of the other second rotating shaft 15 is rotatably connected to the rotating rod 27. The design of the transmission rod 17 and the rotating rod 27 connects the movements of the three clamping mechanisms. When the electric push rod 18 is in operation, it can simultaneously drive the three clamping mechanisms to clamp and secure the hydraulic cylinder.

[0039] Reference Figures 1 to 3The moving assembly includes an electric slide rail 2, which is used to enable the entire clamping mechanism to move accurately to the corresponding position with the hydraulic cylinder to facilitate welding. The bottom of the electric slide rail 2 is fixedly connected to the top of the base 1, which is used to support the entire moving assembly. Two slide bars 3 are provided inside the electric slide rail 2, and the outer walls of the two slide bars 3 are slidably connected to the sliding platform 4. The outer walls of the two ends of the sliding platform 4 are slidably connected to the top of the electric slide rail 2, so that the sliding platform 4 can slide smoothly on the slide bar 3, thereby realizing the precise positioning and movement of the equipment. The bottom of the support block 5 is fixedly connected to the top of the sliding platform 4, which is used for the connection between the clamping mechanism and the moving assembly, so that the clamping mechanism is driven to move when the moving assembly is in operation. The top of the sliding platform 4 is fixedly connected with a rotating assembly for adjusting the angle of the hydraulic cylinder.

[0040] The rotating assembly includes a fixed pile 21, the bottom of the fixed pile 21 is fixedly connected to the top outer wall of the fixed pile 21, and a motor 22 is fixedly connected to the driving end of the motor 22. The outer side of the driving gear 23 is meshed with the outer side of the rotating gear ring 7. The driving gear 23 is driven to rotate by the operation of the motor 22, and the rotation of the driving gear 23 is transmitted to the rotating gear ring 7, so that the rotating gear ring 7 can rotate inside the fixed ring 6, thereby adjusting the angle of the hydraulic cylinder fixed by the clamping mechanism to achieve welding of any part of the hydraulic cylinder.

[0041] Two support columns 24 are fixedly connected to the top of the base 1, and a CNC robotic arm 25 is provided on the top of the support column 24. The driving end of the CNC robotic arm 25 is fixedly connected to a welder 26, so that the CNC robotic arm 25 can drive the welder 26 to perform precise welding operations, thereby improving production efficiency and welding quality.

[0042] Working principle: When fixing the hydraulic cylinder, first pass the hydraulic cylinder into the through hole in the middle of the rotating gear ring 7, turn on the electric push rod 18, and the operation of the electric push rod 18 drives the driving block 19 to move. The movement of the driving block 19 drives one of the V-shaped rods 16 to rotate through the transmission action of the driving rod 20. The rotation of the V-shaped rod 16 drives the rotating column 8 to rotate through the transmission action of the rotating shaft 2 15. The rotation of the rotating column 8 drives the follower ring 9 to rotate. The rotation of the follower ring 9 drives the connecting rod 10 to rotate, and due to the rotation action of the rotating shaft 11, the slider 13 is driven to move axially along the slide block 12, thereby driving the three clamps 14 to clamp and fix the hydraulic cylinder.

[0043] Then, by turning on the electric slide rail 2, the electric slide rail 2 drives the sliding platform 4 to slide axially along the slide rod 3, so that the entire clamping mechanism moves to the welding area with the hydraulic cylinder, and then turning on the motor 22. The operation of the motor 22 drives the driving gear 23 to rotate, and the rotation of the driving gear 23 is transmitted to the rotating gear ring 7, so that the rotating gear ring 7 rotates, thereby rotating the entire clamping mechanism, thereby realizing the rotation of the hydraulic cylinder, facilitating the precise adjustment of the welding position of the hydraulic cylinder, and then turning on the robotic arm and the welder 26 to perform precise welding on the hydraulic cylinder.

[0044] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
