Description

Technical Field

[0001] This utility model belongs to the field of welding technology, specifically relating to an automatic welding gun with a cooling function for welding signboards. Background Technology

[0002] Welding of signs is a crucial step in the sign production process, directly impacting the quality of the finished product and production efficiency. With the rapid development of industrial automation technology and the continuous improvement of automation and intelligence in welding production lines, the labeling of finished steel bars and coils in steel plants has upgraded from manual welding to robotic welding. The automatic welding torch, as a key component of the entire welding system, determines the quality and efficiency of the welded product, and therefore must be given due attention.

[0003] Currently, the robotic welding signage system is installed in harsh environments where the equipment is subjected to high-temperature heat radiation. When the automatic welding torch is in such a harsh working environment for a long time, the accumulation of heat can cause the automatic welding torch to jam, which will affect the stability of the welding torch and directly affect the processing efficiency.

[0004] Therefore, it is urgent to optimize the structure of automatic welding guns, solve the problem of automatic welding guns easily getting hot and jamming, and improve the efficiency of processing operations. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an automatic welding torch with a cooling function, which solves the problem of automatic welding torches easily getting hot and jamming, and improves the efficiency of processing operations.

[0006] To achieve the above objectives, the technical solution of this utility model embodiment is implemented as follows: An automatic welding torch with a cooling function includes a welding base, a welding section, and a cooling section. The welding base has an internal cavity for receiving cavities. One end of the welding section is embedded in the welding base, and the other end, positioned opposite to it, extends through the welding base and is retractably extended along the length of the welding base. The cooling section extends through the welding base and is connected to the internal cavity of the welding base. The welding base, formed by a panel and supporting ribs, has sufficient rigidity to load and withstand uncertain positional loads. The retractable welding section allows for convenient adjustment of the welding torch's position. This design facilitates fine-tuning of the position during operation, improving the flexibility and applicability of welding operations. The cooling section, connected to the internal cavity of the welding seat, allows for easy access to a cooling medium, enabling rapid and convenient heat dissipation from the internal components of the welding seat. This, in turn, effectively cools the components of the automatic welding torch, ensuring that the automatic welding torch can effectively dissipate accumulated heat even under harsh conditions of high-temperature heat radiation. This solves the problem of automatic welding torches easily jamming in existing technologies, improving the stability and safety of automatic welding torch use, and ultimately ensuring the processing efficiency of the entire process.

[0007] Furthermore, the welding seat includes a body, a front baffle and a rear baffle, wherein the body is a container with openings at both ends and a cavity in the middle, and the front baffle and the rear baffle are respectively located at both ends of the body and are sealed to the body.

[0008] Furthermore, the welding seat also includes a spring that is retractably disposed with the welding part, one end of the spring being fixed to the tail end of the welding part, and the other end being fixed against the rear baffle plate.

[0009] Furthermore, it also includes a spring base plate disposed between the spring and the rear baffle.

[0010] Furthermore, it also includes an anti-rotation block that is detachably fixed to the welding part at one end, and extends through the body at the other end, which is opposite to it and extends along the vertical direction.

[0011] Furthermore, it also includes a welding cable fixing buckle disposed on the top surface of the body, the welding cable fixing buckle being electrically connected to the welding part.

[0012] Furthermore, the welding part includes a welding torch shaft, a welding stud chuck, and a fixing nut, wherein one end of the welding torch shaft passes through the welding seat and is telescopically connected to the welding seat, and the other end, which is opposite to it, extends along the length direction of the welding seat; the welding stud chuck is detachably connected to the welding torch shaft through the fixing nut.

[0013] Furthermore, the welding part also includes a linear bearing disposed in the internal cavity of the welding seat and ringed around the outer periphery of the welding torch shaft. One end of the linear bearing abuts against the inner side of the welding seat, and the other end, which is disposed opposite to it, extends along the axis of the welding shaft in a direction away from the welding stud clamp.

[0014] Furthermore, the cooling section includes at least one connector and at least one pipe, wherein the connector is sleeved on the end of the pipe away from the welding seat and is sealed to the pipe; the pipe passes through the welding seat and communicates with the internal cavity of the welding seat.

[0015] Furthermore, it also includes an adjusting bolt that penetrates the rear baffle and is drivably connected to a spring washer, the adjusting bolt being telescopically fixed to the end face of the rear baffle located away from the spring end.

[0016] The automatic welding torch with cooling function provided in the above embodiments effectively reduces its weight by using a welding base made of engineering plastics, providing strong comprehensive mechanical performance and ensuring no current conduction between the welding torch and external connectors during operation, thus providing insulation protection. The welding torch shaft, which is telescopically connected to the welding base, allows the welding nail clamp to extend and retract along the length of the welding base, enabling convenient adjustment of the welding position. A linear bearing, fixed integrally with the welding torch shaft inside the welding base and moving in tandem with it, transmits the reciprocating motion of the spring to the welding torch shaft, allowing flexible adjustment of the welding torch shaft position. A groove machined on the end of the linear bearing allows for convenient and reliable fixation to the spring. A flat surface machined on the outer circumferential surface of the linear bearing, in conjunction with an anti-rotation block, effectively prevents rotational movement of the linear bearing during operation, ensuring operational stability. By machining the welding base into a container with open ends and a central cavity, the welding part is easily fixed inside the welding base, greatly improving the ease of assembly and disassembly. The welding part is elastic at one end... The welding torch is fixed to the housing cavity of the main body, thus enabling a flexible connection between the welding part and the main body. This ensures that the welding torch remains in constant contact with the workpiece during operation and can automatically reset when not in operation. By setting the anti-rotation block perpendicular to the axis of the welding part, the stability and reliability of the welding part during the extension and retraction process are improved. The welding seat, composed of a panel and supporting ribs, has sufficient rigidity to load and withstand uncertain positional loads. The welding part, which is extendable and retractable with the welding seat, allows for convenient adjustment of the welding torch position, facilitating fine-tuning during operation and improving the flexibility and applicability of welding operations. The cooling part, connected to the internal cavity of the welding seat, allows for convenient access to a cooling medium, enabling rapid and convenient heat dissipation from the internal components of the welding seat. This effectively cools the components of the automatic welding torch, ensuring that the automatic welding torch can effectively dissipate accumulated heat under harsh high-temperature heat radiation conditions. This solves the problem of automatic welding torch jamming in existing technologies, improves the stability and safety of automatic welding torch use, and ultimately ensures the processing efficiency of the entire process.

[0020] like Figure 1 As shown in the illustration, an automatic welding torch with a cooling function, according to a partially exemplary embodiment, includes a welding base 10, a welding section 20, and a cooling section 30. The welding base 10 is formed by connecting a panel and supporting ribs, and has a sealed cavity for receiving the internal cavity. One end of the welding section 20 is embedded in the welding base 10, and the other end, disposed opposite to it, extends through the welding section 20 and extends retractably along the length of the welding base 10. The cooling section 30 passes through the welding base 10 and communicates with the internal cavity of the welding base 10. Thus, the welding base, formed by connecting the panel and supporting ribs, has sufficient rigidity to load and withstand uncertain positional loads, and through its interaction with the welding... The retractable welding section of the welding stand allows for convenient adjustment of the welding torch position, facilitating fine-tuning during operation and improving the flexibility and applicability of welding work. The cooling section, connected to the internal cavity of the welding stand, allows for easy access to a cooling medium, enabling rapid and convenient heat dissipation from components inside the welding stand. This effectively cools the components of the automatic welding torch, ensuring that the automatic welding torch can effectively dissipate accumulated heat even under harsh high-temperature heat radiation conditions. This solves the problem of automatic welding torch jamming common in existing technologies, improving the stability and safety of automatic welding torch use, and ultimately ensuring the processing efficiency of the entire process.

[0021] Preferably, in order to minimize the weight of the welding base 10 and improve the convenience and flexibility of the automatic welding gun during disassembly, the welding base 10 is made of engineering plastic. Thus, by using engineering plastic to make the welding base, its own weight can be effectively reduced while providing strong comprehensive mechanical properties. It can also ensure that there is no current conduction between the welding gun and the external connecting parts when the welding gun is working, which plays an insulating protection role and ensures the safety of the entire set of equipment.

[0022] Specifically, such as Figure 2 As shown, the welding base 10 includes a body 11, a front baffle 12, and a rear baffle 13. The body 11 is a container with openings at both ends and a cavity in the middle. The front baffle 12 and the rear baffle 13 are respectively located at both ends of the body 11 and are sealed to the body 11. Thus, by processing the welding base into a container with openings at both ends and a cavity in the middle, the welding part is easily fixed inside the welding base, while the ease of assembly and disassembly is greatly improved. Specifically, one end of the welding part 20 is flexibly fixed inside the cavity of the body 11, and the other end, which is opposite to it, passes through the front baffle 12 and extends along the length of the body 11. Thus, the front baffle restricts the welding part 20, preventing axial movement of the welding part in the working chamber. In this application, a spring is used as an example for illustration. One end of the welding part 20 is flexibly fixed to the inside of the body 11 by the spring. Thus, by means of the spring that is telescopically connected to the welding part, one end of the welding part is flexibly fixed to the receiving cavity of the body, thereby realizing the flexible connection between the welding part and the body. This ensures that the welding torch can always maintain contact with the workpiece during operation and can automatically reset when not in operation. The front baffle limits the welding part and prevents axial movement of the welding part during operation.

[0023] Specifically, the welding base 10 also includes a spring 14 that is telescopically disposed with the welding part 20. One end of the spring 14 is fixed to the tail end of the welding part 20, and the other end, which is disposed opposite to it, abuts against the rear baffle 13. In order to reduce wear on the rear baffle 13 and improve the service life of the welding base 10, a spring base plate 15 is also included between the spring 14 and the rear baffle 13. Furthermore, in order to improve the reliability and stability of the spring during the extension and return process, one end of the spring base plate 15 is machined with a positioning hole for receiving the spring 14, and the other end, which is disposed opposite to it, abuts against the inner surface of the rear baffle 13.

[0024] Optionally, to prevent axial rotation of the welding part 20 during welding operations, an anti-rotation block 16 is also included, which is detachably fixed to the welding part 20 at one end and extends vertically through the body 11 at the other end. Specifically, the anti-rotation block 16 is arranged perpendicular to the axis of the welding part 20 and is detachably fixed by bolts. Thus, by the anti-rotation block fixed to the welding part, after penetrating the body, it moves along a preset trajectory with the welding part, thereby effectively limiting the rotational movement of the welding part and improving the stability and reliability of the welding part during the expansion and contraction process.

[0025] Optionally, to improve the safety of the automatic welding gun during use and enhance the convenience of wiring, a welding cable fixing buckle 17 is also included, which is electrically connected to the welding part 20, located on the top surface of the main body 11. Preferably, the welding cable fixing buckle 17 and the anti-rotation block 16 are located on the same side of the top surface; thereby improving the space utilization of the entire automatic welding gun.

[0026] In summary, the welding base provided in this application, made of engineering plastic, effectively reduces its weight, provides strong comprehensive mechanical properties, and ensures that there is no current conduction between the welding torch and external connectors during operation, thus providing insulation protection. By processing the welding base into a container with open ends and a central cavity, it facilitates the fixing of the welding part inside the welding base while greatly improving the ease of assembly and disassembly. By elastically fixing one end of the welding part to the central cavity, a flexible connection between the welding part and the main body can be achieved, ensuring that the welding torch can always be in contact with the workpiece during operation and can automatically reset when not in operation. By setting the anti-rotation block perpendicular to the axis of the welding part, the stability and reliability of the welding part during the extension and retraction process are improved.

[0027] Preferably, such as Figure 2 As shown, the welding part 20 includes a welding torch shaft 21, a welding stud chuck 22, and a fixing nut 23. One end of the welding torch shaft 21 passes through the welding seat 10 and is telescopically connected to the welding seat 10. The other end, which is opposite to the welding seat 10, extends along the length of the welding seat 10. The welding stud chuck 22 is detachably connected to the welding torch shaft 21 through the fixing nut 23. Thus, by telescopically connecting the welding torch shaft to the welding seat, the welding stud chuck can be telescopically moved along the length of the welding seat, thereby enabling convenient adjustment of the welding position.

[0028] Optionally, cooling holes are machined on the outer peripheral side of the welding torch shaft 21, thereby increasing the heat dissipation area of ​​the welding torch shaft, which helps to dissipate the heat accumulated on the welding torch shaft 21 and improves the cooling efficiency of the welding torch shaft 21.

[0029] Optionally, the welding section 20 further includes a linear bearing 24 disposed within the internal cavity of the welding seat 10 and ringed around the outer periphery of the welding torch shaft 21. One end of the linear bearing 24 abuts against the inner side surface of the welding seat 10, and the other end, disposed opposite to it, extends along the axis of the welding shaft 21 in a direction away from the welding stud clamp 22. Specifically, the linear bearing 24 is fixed inside the bearing hole of the welding seat 10, and the welding torch shaft 21 passes through the linear bearing 24 and extends coaxially with the linear bearing 24.

[0030] In a preferred embodiment of this application, the anti-rotation block 16 is fixed to the welding torch shaft 21 by bolts, and the spring 14 is fixed to the end side of the welding torch shaft 21 located inside the welding seat 10 by bolts, and is disposed against the end side of the anti-rotation block 16.

[0031] In summary, the welding unit provided in this application, through the welding torch shaft that is retractably connected to the welding seat, can drive the welding nail clamp to retract along the length of the welding seat, thereby achieving convenient adjustment of the welding position; through the linear bearing that is fixed integrally with the welding torch shaft inside the welding seat and moves in tandem, the reciprocating motion of the spring is transmitted to the welding torch shaft, thereby achieving flexible adjustment of the welding torch shaft position; through the groove machined on the end side of the linear bearing, it can be conveniently and reliably fixed with the spring; through the flat surface machined on the outer peripheral surface of the linear bearing, which cooperates with the anti-rotation block, the rotational movement of the linear bearing during operation can be effectively prevented, ensuring the stability of the operation.

[0032] Preferably, such as Figure 3 and Figure 4 As shown, the cooling unit 30 includes at least one connector 31 and at least one pipe 32. The connector 31 is disposed on the end side of the welding seat 10 and is sealed to the pipe 32. The pipe 32 passes through the welding seat 10 and is connected to the internal receiving cavity of the welding seat 10. Thus, the cooling medium is quickly connected through the connector and then fed into the receiving cavity through the pipe, where it is circulated and discharged. This achieves the heat dissipation of the relevant components in the internal receiving cavity of the welding seat 10, thereby cooling the relevant components.

[0033] In the preferred embodiment of this application, air is used as the cooling medium. During welding, cold air is introduced through the connector 31 on one side of the welding seat 10 and enters the internal cavity of the welding seat 10 through the pipe 32. The airflow contacts the welding shaft 21 inside the welding seat 10 and then the heat dissipation holes processed on the welding shaft 21 can efficiently achieve heat exchange with the welding shaft 21. The airflow is then output through the connector 31 on the other side, thereby effectively dissipating the heat accumulated on the welding shaft 21, solving the problem of automatic welding guns easily getting hot and jamming, and improving the efficiency of processing operations.

[0034] Optionally, in order to facilitate the adjustment of the downward pressure between the welding part 20 and the workpiece during operation, an adjusting bolt 40 is also included, which passes through the rear baffle 13 and is drivably connected to the spring pad 15. The adjusting bolt 40 is telescopically fixed on the end side of the rear baffle 13 located away from the end side of the spring 14.

[0035] In addition, such as Figure 2 and Figure 4 As shown, in order to improve the safety and reliability of the automatic welding torch during use, a protective cover 50 is also included, which is placed on the anti-rotation block 16 and the welding cable fixing buckle 17. The protective cover 50 extends along the length direction of the welding seat 10.

[0036] In summary, the automatic welding torch with cooling function provided in the above embodiments of this application has at least the following characteristics: the welding base, made of engineering plastic, effectively reduces its weight, provides strong comprehensive mechanical performance, and ensures that there is no current conduction between the welding torch and external connecting parts during operation, thus providing insulation protection; the welding torch shaft, which is telescopically connected to the welding base, can drive the welding nail clamp to telescopically move along the length direction of the welding base, thereby achieving convenient adjustment of the welding position; the linear bearing, which is fixed to the welding torch shaft inside the welding base and moves in tandem with it, transmits the reciprocating motion of the spring to the welding torch shaft, thereby achieving flexible adjustment of the welding torch shaft position; the groove machined on the end side of the linear bearing allows for convenient and reliable fixing to the spring; the flat surface machined on the outer peripheral surface of the linear bearing, in conjunction with the anti-rotation block, effectively prevents the rotational movement of the linear bearing during operation, ensuring the stability of the operation; by machining the welding base into a container with open ends and a cavity in the middle, it is convenient to fix the welding part inside the welding base, while greatly improving the ease of assembly and disassembly; One end of the welding section is elastically fixed to the receiving cavity of the main body, thus achieving a flexible connection between the welding section and the main body. This ensures that the welding torch remains in constant contact with the workpiece during operation and can automatically reset when not in operation. By setting the anti-rotation block perpendicular to the axis of the welding section, the stability and reliability of the welding section during extension and retraction are improved. The welding seat, composed of a panel and supporting ribs, has sufficient rigidity to load and withstand uncertain positional loads. The welding section, which is extendable and retractable with the welding seat, allows for convenient adjustment of the welding torch position, facilitating fine-tuning during operation and improving the flexibility and applicability of welding operations. The cooling section, connected to the internal cavity of the welding seat, allows for convenient access to a cooling medium, enabling rapid and convenient heat dissipation from the internal components of the welding seat. This effectively cools the components of the automatic welding torch, ensuring that the automatic welding torch can effectively dissipate accumulated heat under harsh high-temperature heat radiation conditions. This solves the problem of automatic welding torch jamming in existing technologies, improves the stability and safety of automatic welding torch use, and ultimately ensures the processing efficiency of the entire process.
