Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to an arc welding torch. Background Technology

[0002] Welding, as an important metal joining process, is widely used in industrial manufacturing, automotive repair, and construction. The arc welding torch is a key tool for achieving arc welding; it melts the welding material and workpiece by generating a stable electric arc, thereby forming a strong weld joint. However, traditional arc welding torches have certain limitations in terms of ease of operation and weld quality stability.

[0003] Most existing arc welding torches are operated with one hand, which simplifies the operation process but also brings several challenges:

[0004] 1. Insufficient welding stability: Because it is difficult to ensure stable contact between the welding torch and the welding surface when operating with one hand, especially at the moment of welding, the welding torch may deviate, resulting in unstable welding quality.

[0005] 2. Difficulty in controlling arc height: In applications requiring precise control of welding energy, such as dent repair on vehicle bodies, arc height is crucial to the welding effect. Traditional welding torches have fixed or manually adjustable grounding support columns, which cannot flexibly adapt to dents of different depths, easily resulting in arc heights that are too high or too low, affecting the welding effect.

[0006] 3. High training costs: In order to achieve the correct adjustment of the grounding support column, users need to receive specialized training, which is a significant obstacle for non-professional users.

[0007] 4. Increased risk of incomplete soldering: When soldering substrates or studs, if the solder joint cannot be kept perpendicular to the soldering point, it may cause lateral or longitudinal vibration, which increases the possibility of incomplete soldering and reduces the success rate of soldering.

[0008] 5. Operational complexity: In traditional designs, the central electrode post and external grounding post usually need to be adjusted and locked in place, which increases the complexity and time cost of operation.

[0009] In response to the problems existing in the above-mentioned technologies, the market urgently needs an improved arc welding torch that can provide better ease of operation and welding quality stability. Utility Model Content

[0010] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a pull-arc welding torch, which, through an innovatively designed bracket, positioning post, and handle structure, achieves automatic adaptation to pits of different depths, improves welding position accuracy, reduces the risk of incomplete welds, and enhances operational stability and convenience, thereby improving welding quality and efficiency. The adjustable positioning post, damping structure, and flexible bracket connection method enhance the equipment's adaptability to different welding tasks, reduce the risk of incomplete welds and training costs, making it particularly suitable for high-precision welding tasks in automotive repair. It also simplifies the operation process, improves user experience, and enhances work efficiency.

[0011] The arc welding torch according to an embodiment of the present invention includes:

[0012] The gun body is equipped with a barrel for placing the welding parts;

[0013] The bracket is slidably connected to the gun body;

[0014] A positioning post is connected to the bracket, with one end of the positioning post extending toward one side of the gun barrel;

[0015] A handle, connected to the bracket, is adapted for hand gripping and for driving the bracket to slide along the centerline of the barrel, so as to drive the weldment and one end of the positioning post to abut and position against the workpiece.

[0016] After being positioned with the workpiece, the bracket remains in its current position and welds the workpiece to the workpiece.

[0017] The arc welding torch according to the present invention has at least the following beneficial effects: It introduces an innovative structure that organically combines the torch body, a support slidably connected to the torch body, a positioning post connected to the support and extending towards one side of the torch barrel, and a handle suitable for hand gripping, significantly improving the convenience of welding operation and the stability of welding quality. In practical applications, this welding torch drives the support to slide along the centerline of the torch barrel via the handle, ensuring that the workpiece and one end of the positioning post can jointly contact and position with the workpiece, thus providing a stable foundation for welding. Once positioning is complete, a stable hand grip on the handle keeps the support in its current position, ensuring a constant arc height during subsequent torch operation and effectively counteracting the impact force generated during the instantaneous melting of the molten pool, which can cause welding deviation. For example, operating the welding torch causes the torch barrel to extend and retract, generating a stable arc to melt the welding material and workpiece, and welding the workpiece to the workpiece. This operating mechanism effectively solves the problem of ensuring stable contact between the welding torch and the welding surface in the traditional one-handed operation mode, reducing welding quality issues caused by torch misalignment. Furthermore, this design improves the precision and reliability of the welding process, as users can more quickly and conveniently contact and position the workpiece using the handle, ensuring more accurate and stable contact between the workpiece and the weldment. This not only helps increase the welding success rate and reduce the probability of incomplete welds and other welding defects, thus improving overall welding quality, but is also particularly suitable for applications involving rapid positioning and welding of multiple weldments on uneven workpiece surfaces, such as arranging and welding multiple spacers in the repair of car body dents. Simultaneously, due to the simplified operating procedure, even non-professionals can easily learn to use it, reducing training costs and time investment, and providing operators with a more efficient, reliable, and easy-to-use welding solution.

[0018] According to some embodiments of the present invention, the arc welding torch has two positioning posts, which are respectively arranged on both sides of the torch barrel.

[0019] According to some embodiments of the present invention, the arc welding torch has a positioning post that is adjustablely mounted on the bracket along the centerline of the torch barrel.

[0020] According to some embodiments of the present invention, in the arc welding torch, the handle extends radially along the barrel, and the two positioning posts are respectively arranged on both sides of the handle.

[0021] According to some embodiments of the present invention, the arc welding torch has a positioning post made of metal. The positioning post is able to communicate with the workpiece and drive the weldment to be fixed to the workpiece by arc welding.

[0022] According to some embodiments of the present invention, in the arc welding torch, the end of the positioning post extends obliquely toward one side of the center line of the torch barrel.

[0023] According to some embodiments of the present invention, a damping structure is provided between the support and the gun body to generate resistance to the movement of the support.

[0024] According to some embodiments of the present invention, the arc welding torch has a damping structure including a compression spring, the centerline of which is parallel to the centerline of the torch barrel, one end of which is connected to the torch body and the other end of which is pressed against the bracket.

[0025] According to some embodiments of the present invention, the arc welding torch has a bracket rotatably sleeved on the torch body.

[0026] According to some embodiments of the present invention, the arc welding torch has a support threadedly connected to a fastening screw, which can push against the torch body to drive the support to be fixed relative to the torch body.

[0040] Welding, as an important metal joining process, is widely used in industrial manufacturing, automotive repair, and construction. The arc welding torch is a key tool for achieving arc welding; it melts the welding material and workpiece by generating a stable electric arc, thereby forming a strong weld joint. However, traditional arc welding torches have certain limitations in terms of ease of operation and weld quality stability.

[0041] Most existing arc welding torches are operated with one hand, which simplifies the operation process but also brings several challenges:

[0042] 1. Insufficient welding stability: Because it is difficult to ensure stable contact between the welding torch and the welding surface when operating with one hand, especially at the moment of welding, the welding torch may deviate, resulting in unstable welding quality.

[0043] 2. Difficulty in controlling arc height: In applications requiring precise control of welding energy, such as dent repair on vehicle bodies, arc height is crucial to the welding effect. Traditional welding torches have fixed or manually adjustable grounding support columns, which cannot flexibly adapt to dents of different depths, easily resulting in arc heights that are too high or too low, affecting the welding effect.

[0044] 3. High training costs: In order to achieve the correct adjustment of the grounding support column, users need to receive specialized training, which is a significant obstacle for non-professional users.

[0045] 4. Increased risk of incomplete soldering: When soldering substrates or studs, if the solder joint cannot be kept perpendicular to the soldering point, it may cause lateral or longitudinal vibration, which increases the possibility of incomplete soldering and reduces the success rate of soldering.

[0046] 5. Operational complexity: In traditional designs, the central electrode post and external grounding post usually need to be adjusted and locked in place, which increases the complexity and time cost of operation.

[0047] In response to the problems existing in the above-mentioned technologies, the market urgently needs an improved arc welding torch that can provide better ease of operation and welding quality stability.

[0048] Therefore, such as Figures 1 to 3As shown, the arc welding torch proposed in this utility model includes a torch body 100, a bracket 200 slidably connected to the torch body 100, a positioning post 210 connected to the bracket 200, and a handle 220 connected to the bracket 200. The torch body 100 is provided with a barrel 110 for placing the workpiece. One end of the positioning post 210 extends toward one side of the barrel 110. The handle 220 is adapted for hand gripping and is used to drive the bracket 200 to slide along the center line of the barrel 110, so as to drive the workpiece and one end of the positioning post 210 to abut and position against the workpiece. After positioning with the workpiece, the bracket 200 remains in the current position and welds and fixes the workpiece to the workpiece. It should be noted that an innovative structure is introduced, organically combining the torch body 100, the support 200 slidably connected to the torch body 100, the positioning post 210 connected to the support 200 and extending towards the barrel 110, and the handle 220 suitable for hand gripping, significantly improving the convenience of welding operation and the stability of welding quality. In practical applications, this welding torch drives the support 200 to slide along the centerline of the barrel 110 via the handle 220, ensuring that the workpiece and one end of the positioning post 210 can jointly abut and position against the workpiece, thus providing a stable foundation for welding. Once positioning is completed, the hand firmly grips the handle 220, keeping the support 200 in its current position, thereby ensuring a constant arc height during subsequent torch operation and effectively counteracting the impact force generated during the instantaneous melting of the molten pool, which can cause welding deviation. For example, operating the welding torch causes the barrel 110 to extend and retract, generating a stable arc to melt the welding material and the workpiece, and welding the workpiece to the workpiece. It's easy to understand that this operating mechanism effectively solves the problem of ensuring stable contact between the welding torch and the welding surface in traditional single-handed operation, reducing welding quality issues caused by torch misalignment. Furthermore, this design improves precision and reliability during the welding process, as users can more quickly and easily contact and position the workpiece using the handle 220, ensuring more accurate and stable contact. This not only helps increase the welding success rate and reduce the probability of incomplete welds and other welding defects, improving overall welding quality, but is also particularly suitable for applications involving rapid positioning and welding of multiple workpieces on uneven surfaces. For example, if the workpiece is a spacer 111, multiple spacers 111 may need to be arranged and welded in the repair of car body dents to smooth out the dent. Simultaneously, due to the simplified operating procedure, even non-professionals can easily learn to use it, reducing training costs and time investment, and providing operators with a more efficient, reliable, and easy-to-use welding solution.

[0049] In some embodiments, there is only one positioning post located on the outside of the barrel (not shown in the figure). This single positioning post, together with the weldment, abuts against the workpiece for positioning, which can adapt to particularly uneven workpiece welding surfaces. However, when the barrel extends and retracts to complete welding, the force on a single positioning post is unstable, making it prone to skewness and affecting welding quality. Therefore, in some embodiments of this invention, such as... Figure 1 As shown, there are two positioning posts 210, which are respectively arranged on both sides of the barrel 110, significantly enhancing the positioning accuracy and stability of the welding torch during welding. It is easy to understand that the dual positioning post system not only provides more stable support for the workpiece, avoiding the instability that a single positioning post might cause, but also helps ensure uniform contact between the workpiece and the weldment, resulting in a more balanced distribution of arc energy during welding, thereby improving the quality and strength of the weld joint. This design is particularly suitable for applications requiring high-precision welding, such as the connection or repair of precision components, effectively reducing the probability of incomplete welds and other welding defects, thus improving the overall welding quality. Furthermore, in some embodiments of this invention, the handle 220 extends radially along the barrel 110, with two positioning posts 210 respectively arranged on both sides of the handle 220. On the one hand, this optimizes the ergonomics of the welding torch; this layout allows the operator to naturally apply force when holding the handle 220, facilitating precise control of the welding torch's position and angle. On the other hand, the handle 220, located between the two positioning posts 210, forms a stable triangular support structure. For example, the two positioning posts 210 are located on the upper and lower sides of the barrel 110, respectively, preventing the barrel 110 from tilting vertically. The handle 220 provides a stabilizing force on the radial side of the barrel 110, thus preventing tilting to the left or right. Furthermore, this compact and rational design makes the welding torch easier to carry and operate, especially in space-constrained working environments. The relative positions of the handle 220 and the positioning posts 210 also ensure that hand movements do not interfere with the contact between the positioning posts 210 and the workpiece during welding, further improving welding stability and quality, and making operation smoother and more efficient. In some embodiments, there is a single handle 220, arranged on the left side of the welding torch's forward alignment direction, suitable for the user to hold the control bracket 200 with their left hand. It is easy to understand that in this case, the user's right hand can be used to operate the welding torch's start button. In some embodiments, there is a single handle 220, which is arranged on the right side of the welding torch forward alignment direction to accommodate a user's right-hand grip on the control bracket 200. The specific arrangement can be determined based on the user's left- or right-handed usage habits. In some embodiments, there are two handles (not shown), arranged on the left and right sides of the welding torch forward alignment direction respectively, for the user to use selectively.

[0050] Refer to Figure 3In some embodiments of this invention, the bracket 200 is rotatably sleeved on the gun body 100, thereby allowing for convenient rotation and adjustment of the bracket 200's position. This enables the positioning pin 210 to be adjusted around the centerline of the barrel 110, thus accommodating more complex workpiece welding surfaces and finding the most suitable contact point for the positioning pin 210. Furthermore, based on the different hand-handed usage habits of users, the handle 220 can also be easily adjusted to different positions on the barrel 110. Optionally, the handle 220 can be detachably installed on the bracket 200 for easy replacement, maintenance, and unpacking. For example, the handle 220 and the bracket 200 are fixed together by a threaded connection.

[0051] Refer to Figures 1 to 3 In some embodiments of this invention, the positioning post 210 is adjustablely mounted on the bracket 200 along the centerline of the barrel 110, giving the welding torch great flexibility. Optionally, the end of the positioning post 210 facing away from the barrel passes through the end face of the bracket 200 and is threadedly connected to the bracket 200. Furthermore, the positioning post 210 is threadedly connected to a fastening nut 211. By tightening the fastening nut 211, the positioning post 210 and the bracket 200 are pressed and fixed. Besides adjusting the distance between the positioning post 210 and the barrel end by pushing the bracket 200, further adjustments to the installation position of the positioning post 210 and the bracket allow for a greater adjustment of the relative distance between the end of the positioning post 210 and the end of the barrel 110. This allows the welding torch to adapt more comprehensively to complex tasks such as welding points of different depths or dent repair, which is particularly important in fields such as automotive body repair. Because users can precisely control the arc height according to specific needs, ensuring optimal results for each weld and reducing the risk of incomplete welds. At the same time, it also improves the equipment's applicability to a variety of welding tasks, allowing the welding torch to be used more widely in different industrial environments, thus enhancing the user experience and work efficiency.

[0052] In some embodiments, the positioning post 210 only serves the function of aligning and positioning with the workpiece and does not participate in the conductive function. In this case, the positioning post 210 can be made of conductive metal materials such as steel or copper, or non-conductive non-metallic materials such as plastic or wood. However, in order to further integrate the function of the positioning post 210, in some embodiments of this utility model, the positioning post 210 is made of metal, and the positioning post 210 can conduct electricity with the workpiece, driving the workpiece and the workpiece to be fixed together by arc welding. It is easy to understand that the positioning post 210 is made of metal and has a conductive function, ensuring that the current required for arc welding can be smoothly conducted between the workpiece and the workpiece, which is crucial for achieving high-quality welding. Commonly, the gun barrel 110 located in the center is connected to the positive electrode for conductivity, and the positioning posts 210 on both sides are connected to the negative electrode for conductivity, thereby further stabilizing the arc to generate a molten pool and improving the success rate of welding. It should be noted that the metal positioning posts 210 have excellent electrical conductivity, enabling them to quickly establish a stable current path during welding, ensuring the reliability of the electrical connection. Simultaneously, since the positioning posts 210 directly participate in the welding process, their conductivity also helps maintain temperature control during welding, promoting the formation and cooling of the molten pool, thus affecting the mechanical properties of the final weld joint. Furthermore, the choice of metal material increases the durability and wear resistance of the positioning posts 210, extending the service life of the equipment.

[0053] Refer to Figure 1 and Figure 2 In some embodiments of this invention, the end of the positioning post 210 extends obliquely towards one side of the centerline of the barrel 110, further optimizing the user experience of the welding torch. This oblique structure provides better guidance at the start of welding, reducing the distance between the torch and the workpiece, helping the welding torch to establish an arc smoothly, and reducing vibrations that may occur in the early stages of welding. Furthermore, the oblique design of the end of the positioning post 210 not only improves the positioning effect after contact with the workpiece, but also helps maintain the correct posture of the welding torch throughout the welding process, preventing torch deviation, thereby improving welding quality and efficiency.

[0054] In some embodiments of this invention, a damping structure is provided between the support 200 and the gun body 100 to resist the movement of the support 200. This feature is crucial for maintaining the stable position of the welding gun during the welding process. On the one hand, the damping prevents the support 200 from sliding accidentally, especially when the operator applies uneven force. It helps maintain the predetermined position of the welding gun and ensures the consistency of welding parameters. This stability is essential for obtaining high-quality welding results, especially when performing welding tasks that require maintaining the same posture for a long time. On the other hand, the damping structure also improves the user experience, providing a pushing sensation for the user to push the support 200, making the operation smoother and more responsive. In some embodiments, the support is sleeved and installed on the gun body, and a friction ring (not shown in the figure), such as a rubber ring or silicone ring, is installed on the inner peripheral wall of the support. The inner side of the friction ring is pressed against the gun body, thereby generating a large frictional force between the friction ring and the gun body when the support is pushed, providing a damped feedback sensation for the user's pushing. In addition, when the support is pushed to the appropriate position and held still, the friction ring can generate a large static frictional force between itself and the gun body, allowing the support to remain in the current position. In some embodiments of this utility model, such as Figure 2 and Figure 3 As shown, the damping structure includes a compression spring 120. The centerline of the compression spring 120 is parallel to the centerline of the barrel 110. One end of the compression spring 120 is connected to the gun body 100, and the other end presses against the bracket 200. The user can adjust the compression degree of the compression spring 120 by moving the bracket 200 according to the specific welding task, and obtain suitable operating feel and stability within the moving bracket 200. Optionally, there is one compression spring 120, which presses against the middle of the bracket 200; or there are multiple compression springs 120, which press against multiple positions on the same end face of the bracket 200.

[0055] In some applications, the welding torch requires adjustment of the bracket 200 position for each use, such as welding uneven car body surfaces. In other applications, the welding torch can perform welding operations on multiple workpieces after a single adjustment of the bracket 200 position, such as welding flat sheet metal surfaces. For these applications, please refer to... Figures 1 to 3In some embodiments of this utility model, the bracket 200 is threadedly connected to a fastening screw 230. The fastening screw 230 can push against the gun body 100 to drive the bracket 200 and the gun body 100 to be relatively fixed. This allows the user to fix the bracket 200 and the gun body 100 relatively after adjusting the position, thereby effectively preventing any unnecessary movement during the welding process. It is easy to understand that fixing the bracket 200 and the gun body 100 means that the position of the positioning post 210 and the gun body 100 is relatively fixed. This ensures that the distance between the end of the positioning post 210 and the end of the workpiece remains constant. Therefore, during operation, the arc height of the workpiece remains consistent each time, which is crucial for ensuring welding quality and product consistency. By simply tightening the fastening screw 230, the user can quickly lock the position of the bracket 200, avoiding the loosening problems that may occur in traditional designs, while also simplifying the operation process and improving work efficiency. It is easy to understand that when it is necessary to keep the bracket 200 and the gun body 100 in a fixed position, the user can turn the fastening screw 230 in the first direction, such as clockwise, so that the fastening screw 230 presses against the gun body 100 and fixes it; when it is necessary to release the bracket 200 and the gun body 100, the user can turn the fastening screw 230 in a direction away from the first direction, such as counterclockwise, so that the fastening screw 230 separates from the gun body 100.

[0056] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
