Description

Technical Field

[0001] The utility model relates to the technical field of welding torches, in particular to a welding torch with a welding distance adjustment function. Background Art

[0002] A welding torch, also known as a welding gun, is a tool used to weld or preheat ferrous or non-ferrous metal workpieces using oxygen and medium- or low-pressure acetylene as heat sources. It is the primary tool for gas welding. The torch's function is to evenly mix combustible gas and oxygen in a specific ratio and eject them from the nozzle at a specific velocity, creating a flame with a specific energy efficiency and composition suitable for welding requirements and stable combustion. The quality of the welding torch directly affects the quality of gas welding. Therefore, the torch must be able to precisely adjust the ratio of oxygen to combustible gas and the flame energy efficiency, ensuring that the ejection velocity of the mixed gas is equal to or greater than the combustion velocity, ensuring stable flame combustion. Furthermore, the torch must be lightweight, easy to operate, and safe and reliable.

[0003] After searching, it was found that in the prior art, a utility model with publication number CN216541301U discloses a double-headed welding torch, including a mixed gas pipe, a tee, a first elbow and a second elbow.

[0021] 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.

[0022] Example: See Figure 1-4 The utility model provides a technical solution: a welding torch with a welding distance adjustment function, comprising a main rod 1, a screw rod 18 is provided at the top of the main rod 1, and a slide plate 19 is provided on the outer ring of the screw rod 18. A through hole 20 is penetrated at the top of the slide plate 19, and a second U-shaped rod 22 is connected to both sides of the slide plate 19. A slide groove 4 is provided on the front of the main rod 1, and a slide rod 5 is provided in the inner cavity of the slide groove 4. A slider 7 is provided on the outer ring of the slide rod 5, and one end of the slider 7 is connected to a support plate 10, and the top of the support plate 10 is connected to a first connecting plate 11, and one side of the first connecting plate 11 is connected to a first U-shaped rod 12, and the bottom end of the support plate 10 is connected to a second connecting plate 13, and one end of the second connecting plate 13 is connected to a sleeve 14, and the inner cavity of the sleeve 14 is provided with a welding torch nozzle 15.

[0023] A support plate 27 is rotatably connected between the first U-shaped rod 12 and the second U-shaped rod 22 .

[0024] The outer ring of the screw rod 18 is threadedly connected to a butterfly nut 23 . The butterfly nut 23 is located above the slide plate 19 . A compression spring 25 is provided below the slide plate 19 .

[0025] In this embodiment, when welding materials of different sizes, the butterfly nut 23 is first rotated. At this time, the butterfly nut 23 moves axially on the outer ring of the screw rod 18 through the thread to adjust the distance between the butterfly nut 23 and the main rod 1. When it is necessary to process larger materials, the butterfly nut 23 is adjusted downward. At this time, the butterfly nut 23 pushes the slide plate 19 downward, and the two ends of the slide plate 19 drive one end of the support plate 27 to rotate through the second U-shaped rod 22. At this time, the other end of the support plate 27 pushes the first connecting plate 11 through the first U-shaped rod 12 to expand the distance between the two welding torch nozzles 15. The compression spring 25 is used to provide support force to the slide plate 19. When the nut 23 moves upward, the compression spring 25 pushes the slide plate 19 upward, and the support plate 27 pulls the first connecting plate 11 through the first U-shaped rod 12 to shorten the distance between the two welding torch nozzles 15, so that the device can weld materials of different sizes to improve the applicability of the device; when the first connecting plate 11 is pushed by the support plate 27, the first connecting plate 11 drives the slider 7 to move on the outer circle of the slide rod 5 through the support plate 10, thereby limiting the movement trajectory of the welding torch nozzle 15, making the use of the device more stable, and the butterfly nut 23 is a prior art, which can be convenient for the staff to rotate it to improve the convenience of use of the device.

[0026] Among them, the outer ring of the slide rod 5 is provided with multiple ball sliding grooves 6, the inner wall of the slider 7 is provided with multiple ball mounting grooves 8, the inner cavity of the ball mounting groove 8 is provided with multiple balls 9, and the balls 9 are movably connected to the ball sliding grooves 6.

[0027] In this embodiment, when the slider 7 moves on the outer ring of the slide rod 5, the ball 9 rolls in the inner cavity of the ball groove 6 to reduce the friction between the slider 7 and the slide rod 5, making the movement of the slider 7 smoother, thereby making the device easy to adjust.

[0028] Wherein, both sides of the welding torch nozzle 15 are connected to a connecting shaft 16 , and one end of the connecting shaft 16 is rotatably connected to a roller 17 .

[0029] In this embodiment, Figure 2 As shown, the welding torch nozzle 15 is located between two rollers 17, and the bottom end of the welding torch nozzle 15 is higher than the rollers 17. When the device is working, the rollers 17 roll on the surface of the material. While playing a guiding role, it can prevent the end of the welding torch nozzle 15 from making direct contact with the material, thereby causing tempering, thereby improving the safety of the device.

[0030] Among them, a gasket 24 is arranged between the butterfly nut 23 and the slide plate 19, a fixing ring 21 is arranged at both ends of the through hole 20, the outer ring of the slide rod 5 is provided with a reset spring 26, the slider 7 is located between the two reset springs 26, and both ends of the main rod 1 are connected to the connecting block 2, and the inner cavity of the connecting block 2 is penetrated by a connecting hole 3.

[0031] In this embodiment, the connecting block 2 and the connecting hole 3 are used to connect the device to an external transmission device; the fixing ring 21 can reinforce the through hole 20 to prevent the slide plate 19 from breaking, thereby improving the service life of the device; the gasket 24 is a prior art and can prevent the butterfly nut 23 from loosening, thereby improving the stability of the device; the reset spring 26 is used to apply thrust to the slider 7. When the butterfly nut 23 moves upward, the slider 7 can be quickly pushed back to improve the adjustment efficiency of the device. At the same time, the pressure of the compression spring 25 can be relieved to prevent the compression spring 25 from fatigue, thereby improving the practicality of the device.
