Description

Technical Field

[0001] This utility model relates to the field of welding technology, specifically to a metal product welding robot that can quickly change welding torches. Background Technology

[0002] Existing metal welding robots generally suffer from cumbersome disassembly and assembly processes and inconvenient operation when changing welding guns, resulting in low welding gun replacement efficiency. Moreover, most robots lack effective protection for internal disassembly and assembly components, allowing welding slag and dust generated during the welding process to easily enter the internal structure, causing component damage. This not only shortens the robot's service life but also increases maintenance costs, making it difficult to meet the needs of efficient and stable welding operations.

[0003] To address this issue, we propose a metal welding robot with a rapidly changeable welding torch. Utility Model Content

[0004] The purpose of this invention is to provide a metal welding robot that can quickly change welding torches, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a metal product welding robot with a quick-change welding torch, comprising a robotic arm, the lower end of which is movably connected to a mounting block via a shaft, a T-shaped block being mounted on the mounting block via a disassembly and assembly assembly, the T-shaped block being engaged with a mounting groove on the side of the mounting block, a welding torch being fixedly mounted on the side of the T-shaped block away from the robotic arm, a first inner groove being provided on the top surface of the mounting block, a second inner groove being provided on the top surface of the T-shaped block communicating with the first inner groove, and the disassembly and assembly assembly being disposed between the first inner groove and the second inner groove.

[0006] Preferably, the disassembly and assembly assembly includes a short column, the bottom end of which is fixedly installed to the bottom of the inner wall of the first inner groove. A circular block is rotatably mounted in an annular groove on the outer wall of the short column. An arc-shaped rod is fixedly installed on the edge of the circular block. A locking block is fixedly installed at the end of the arc-shaped rod away from the circular block. The locking block is engaged in a slot on the inner wall of the second inner groove. With the short column providing fixed support, the circular block drives the arc-shaped rod to rotate, so that the locking block is precisely engaged in the slot. This enables quick connection and disassembly of the mounting block and the T-block, providing core structural support for welding torch replacement. The operation is convenient and the connection is stable, preventing the welding torch from loosening during welding.

[0007] Preferably, the first inner groove and the second inner groove are the same size and shape to ensure that they fit perfectly when they are connected. This provides a unified installation space for disassembling and assembling components, and ensures the flatness of the structure after the mounting block and the T-block are assembled. It avoids assembly deviations caused by mismatch of the grooves and improves the overall structural stability.

[0008] Preferably, a torsion spring is fixedly installed on the bottom surface of the circular block and sleeved on the outside of the annular groove. The end of the torsion spring away from the circular block is fixedly installed on the bottom of the inner wall of the annular groove. The torsion spring can automatically reset after the circular block rotates, causing the locking block to spring back into the locking groove. There is no need to manually adjust the position of the locking block, which simplifies the welding gun installation process. At the same time, it enhances the tightness of the fit between the locking block and the locking groove, further improving the connection reliability.

[0009] Preferably, a swivel cap is fixedly installed on the top surface of the circular block and sleeved on the outside of the short column. The outer wall of the swivel cap has anti-slip texture. The swivel cap provides a convenient point of force application for the operator. The anti-slip texture can increase the friction between the hand and the swivel cap, avoid slipping when rotating, facilitate quick rotation of the circular block to complete the disassembly and assembly operation, and improve the efficiency of changing the welding gun.

[0010] Preferably, the top surface of the swivel cap is provided with a sealing plug that engages with the first inner groove and the second inner groove. The sealing plug can block the openings of the first inner groove and the second inner groove, preventing welding slag, dust or coolant generated during the welding process from entering the groove, protecting the internal disassembly and assembly components from damage, extending the service life of the robot, and reducing maintenance costs.

[0011] Preferably, the size of the card block is smaller than the size of the card slot.

[0012] This invention provides a metal welding robot with a quickly changeable welding torch. This metal welding robot with a quickly changeable welding torch has the following advantages:

[0013] This metal welding robot, capable of quickly changing welding torches, allows for rapid connection and disassembly of the mounting block and T-block through component assembly. Features include a textured cap for easy operation, an automatic torsion spring for simplified reset, and two inner grooves that fit together to prevent assembly deviations. A locking block and slot prevent the welding torch from loosening during welding, ensuring structural stability. A sealing plug blocks the inner groove openings, preventing welding slag and dust, protecting internal components, extending the robot's lifespan, and reducing maintenance costs.

[0022] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0023] like Figure 1-7 As shown, this utility model provides a technical solution: a metal product welding robot with a quick-change welding torch, including a robotic arm 1. The lower end of the robotic arm 1 is movably connected to a mounting block 3 via a shaft. A T-shaped block 5 is mounted on the mounting block 3 via a disassembly and assembly component. The T-shaped block 5 is engaged with a mounting groove 4 on the side of the mounting block 3. A welding torch 2 is fixedly mounted on the side of the T-shaped block 5 away from the robotic arm 1. The top surface of the mounting block 3 has a first inner groove 7, and the top surface of the T-shaped block 5 has a second inner groove 8 that communicates with the first inner groove 7. The disassembly and assembly component is positioned between the first inner groove 7 and the second inner groove 8. The first inner groove 7 and the second inner groove 8 are identical in size and shape to ensure a perfect fit when they are connected. This provides a unified installation space for the disassembly and assembly component and ensures the flatness of the structure after the mounting block 3 and the T-shaped block 5 are assembled, avoiding assembly deviations caused by mismatched grooves and improving the overall structural stability.

[0024] The assembly and disassembly components include a short column 14, the bottom of which is fixedly installed to the bottom of the inner wall of the first inner groove 7. A circular block 13 is rotatably mounted in an annular groove on the outer wall of the short column 14. An arc-shaped rod 12 is fixedly installed on the edge of the circular block 13. A locking block 11 is fixedly installed at the end of the arc-shaped rod 12 away from the circular block 13. The locking block 11 is locked in a slot 10 on the inner wall of the second inner groove 8. The size of the locking block 11 is smaller than the size of the slot 10. It is fixedly supported by the short column 14. The circular block 13 drives the arc-shaped rod 12 to rotate, so that the locking block 11 is precisely locked into the slot 10, realizing the quick connection and disassembly of the mounting block 3 and the T-shaped block 5. It provides core structural support for the replacement of the welding gun, which is convenient to operate and has a stable connection, preventing the welding gun from loosening during the welding process.

[0025] Among them, a torsion spring 15 is fixedly installed on the bottom surface of the circular block 13 and sleeved on the outside of the annular groove. The end of the torsion spring 15 away from the circular block 13 is fixedly installed on the bottom of the inner wall of the annular groove. The torsion spring 15 can automatically reset after the circular block rotates, causing the locking block 11 to spring back into the locking groove 10. There is no need to manually adjust the position of the locking block, which simplifies the welding gun installation process. At the same time, it enhances the tightness of the fit between the locking block 11 and the locking groove 10, further improving the connection reliability.

[0026] Furthermore, a screw cap 16 is fixedly installed on the top surface of the circular block 13 and sleeved on the outside of the short column 14. The outer wall of the screw cap 16 has anti-slip texture. The screw cap 16 provides a convenient point of force application for the operator. The anti-slip texture can increase the friction between the hand and the screw cap 16, avoid slipping when rotating, and facilitate quick rotation of the circular block 13 to complete the disassembly and assembly operation, thereby improving the efficiency of changing the welding gun.

[0027] Furthermore, the top surface of the swivel cap 16 is provided with a sealing plug 6 that engages with the first inner groove 7 and the second inner groove 8. The sealing plug 6 can block the openings of the first inner groove 7 and the second inner groove 8, preventing welding slag, dust or coolant generated during the welding process from entering the groove, protecting the internal disassembly and assembly components from damage, extending the service life of the robot, and reducing maintenance costs.

[0028] When using this metal welding robot with quick-change welding gun, rotating the screw cap 16 rotates the circular block 13, which in turn causes the arc rod 12 to rotate the locking block 11 until it is aligned with the center line of the first inner groove 7. Then, the T-shaped block 5 is inserted into the mounting groove 4 from below the mounting block 3 until the second inner groove 8 on the top surface of the mounting block 3 is at the same level as the first inner groove 7. Then, the screw cap 16 is loosened, and the locking block 11 is inserted into the slot 10 under the action of the torsion spring 15, thus achieving the installation purpose. Finally, the sealing plug 6 is inserted into the first inner groove 7 and the second inner groove 8. When the welding gun 2 needs to be replaced, simply pull out the sealing plug 6, rotate the screw cap 16 again to disengage the locking block 11 from the slot 10, and then remove the T-shaped block 5 and the old welding gun 2 along the mounting groove 4.

[0029] The above description is merely an illustrative embodiment of this utility model and is not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above. Each technical feature described in the specification of this utility model can be used individually or in combination as needed. Therefore, this utility model naturally covers other combinations and specific applications related to the points of this utility model.
