Description

Technical Field

[0001] This utility model belongs to the field of stud welding gun technology, and more specifically, it relates to an airborne automated stud welding gun. Background Technology

[0002] Stud welding guns are specialized welding tools used to firmly connect studs to base materials through welding. Their core function is to use a specific welding process to form a molten pool at the contact point between the stud and the base material, which then cools and solidifies, ultimately achieving a metallurgical bond. They are widely used in industrial fields such as automobile manufacturing, sheet metal processing, construction machinery, and shipbuilding. Existing stud welding guns use copper sleeves as guides for the gun core, resulting in high frictional resistance, inflexible operation, and a tendency to jam. In addition, the large assembly gaps and low guiding accuracy make it easy to bend the push rod. The pin-driven anti-rotation mechanism also has high frictional resistance, and the gun core floating mechanism does not reset in time. After long-term operation, wear intensifies, leading to a significant reduction in the service life of the welding gun. Therefore, an airborne automated stud welding gun is proposed. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an airborne automated stud welding torch, which solves the problems mentioned in the background art, such as the high frictional resistance, inflexible operation, and easy jamming caused by using a copper sleeve as a guide for the torch core, as well as the large assembly gap, low guiding accuracy, easy bending of the top rod, high frictional resistance caused by the use of a pin in the anti-rotation mechanism, and untimely reset of the torch core floating mechanism, which leads to accelerated wear after long-term operation and a significant reduction in the service life of the welding torch.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an airborne automated stud welding torch, comprising a torch body and a cylinder cover. A cylinder is fixedly mounted on the inner side of the cylinder cover. An adjusting screw is threadedly connected to the end of the cylinder cover away from the torch body. A linear bearing is fixedly mounted on the end of the torch body away from the cylinder cover. A torch core is mounted on the inner side of the linear bearing. A torch core connecting block is threadedly connected to the outer side of the torch core near the cylinder. A rolling bearing is embedded on the inner side of the torch body. A connecting copper post is mounted on the inner side of the rolling bearing. A connecting copper strip is fixed to the other end of the connecting copper post.

In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] Please see Figures 1 to 4This utility model provides a technical solution: an airborne automated stud welding torch, including a torch body 1 and a cylinder cover 2. A cylinder 3 is fixedly mounted on the inner side of the cylinder cover 2. An adjusting screw 4 is threadedly connected to the end of the cylinder cover 2 away from the torch body 1. A linear bearing 5 is fixedly mounted on the end of the torch body 1 away from the cylinder cover 2. A torch core 6 is mounted on the inner side of the linear bearing 5. A torch core connecting block 7 is threadedly connected to the outer side of the torch core 6 near the cylinder 3. A rolling bearing 8 is embedded on the inner side of the torch body 1. A wiring copper post 9 is mounted on the inner side of the rolling bearing 8. A wiring copper strip 10 is fixed to the other end of the wiring copper post 9. A tightening nut 11 is also threadedly connected to the outer side of the torch core 6 near the cylinder 3. A spring 1 abuts against the tightening nut 11 and the cylinder 3. 2. A push rod 13 is slidably connected to the inner side of the gun core 6. A connecting shaft 14 is fixed to the end of the push rod 13 near the cylinder 3. A nail receiving mechanism 15 is fixed to the end of the gun core 6 away from the cylinder 3. A locking nut sleeve 16 is threaded to the end of the nail receiving mechanism 15 away from the gun core 6. A clamp 17 is fixed between the locking nut sleeve 16 and the nail receiving mechanism 15. The gun body 1 and the cylinder cover 2 are fixedly connected by screws. One end of the adjusting screw 4 abuts against one end of the cylinder 3. The axis of the push rod 13 coincides with the axis of the gun core 6. The output end of the cylinder 3 is fixedly connected to the inner side of the connecting shaft 14. One end of the wiring copper post 9 is fixedly connected to the outer side of the gun core connecting block 7. The axis of the push rod 13 and the axis of the cylinder 3 are in the same straight line. During operation, after the stud falls into the receiving mechanism 15, the cylinder 3 pushes the push rod 13 to push the stud into the chuck 17, making initial contact between the stud end and the workpiece surface, applying slight pressure to ensure stable subsequent arc ignition. The DC pulse power supply is transmitted to the stud sequentially through the connecting copper strip 10, connecting copper post 9, gun core connecting block 7, gun core 6, and push rod 13, so that the stud and the workpiece output arc ignition current, rapidly heating the contact area between the stud end and the workpiece surface, causing the metal of both to melt and form a molten metal pool. When the heating time reaches the preset value, the cylinder 3 pushes the stud downward rapidly through the push rod 13. Under pressure, the molten metal at the stud end and the molten metal pool on the workpiece surface are fully squeezed and diffused, expelling gas and impurities from the molten metal, forming a tight fusion zone. After pressurization, the welding gun maintains pressure. The pressure is maintained for 10-50 milliseconds to ensure stable cooling and crystallization of the molten metal under pressure, preventing joint cracking due to excessively rapid cooling. After the pressure holding period, the welding power supply is cut off, the arc is extinguished, and the chuck 17 leaves the workpiece surface. Through the above process, the linear bearing 5 is used as the gun core guide, resulting in low friction, flexible operation, and less likelihood of jamming. The assembly gap is small, the guiding accuracy is high, and it is not easy to bend the top rod. The anti-rotation mechanism uses the rolling bearing 8, which has low frictional resistance. The gun core 6 uses the spring 12 and the linear bearing 5 to achieve free extension and retraction. The gun core floating mechanism resets in time, avoiding the problem of accelerated wear after long-term operation, which greatly shortens the service life of the welding gun. The structure is simple, saving a lot of parts processing costs. The internal mechanism operates smoothly and is not easy to jam, extending the service life. It can be installed on various production lines.

[0022] The specific usage and function of this embodiment: When the stud falls into the nail receiving mechanism 15, the cylinder 3 pushes the push rod 13 to push the stud into the chuck 17, so that the end of the stud makes initial contact with the workpiece surface and applies slight pressure to ensure the stability of subsequent arc ignition. The DC pulse power supply is transmitted to the stud in sequence through the connecting copper strip 10, connecting copper post 9, gun core connecting block 7, gun core 6 and push rod 13, so that the arc ignition current is output between the stud and the workpiece, which quickly heats the contact area between the end of the stud and the surface of the workpiece, so that the metals of both melt. A molten metal pool is formed. When the heating time reaches the preset value, the cylinder 3 pushes the stud downwards quickly through the push rod 13. The molten metal at the end of the stud and the molten metal pool on the surface of the workpiece are fully squeezed and diffused under pressure, expelling gas and impurities from the molten metal and forming a tight fusion zone. After pressurization, the welding torch maintains the pressure for 10-50 milliseconds to ensure that the molten metal cools and crystallizes stably under pressure, avoiding joint cracking due to excessive cooling. After the pressure holding is completed, the welding power supply cuts off the current, the arc is extinguished, and the chuck 17 leaves the workpiece surface.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
