Description

Technical Field

[0001] This utility model relates to the field of welding torch technology, specifically to an argon arc welding torch. Background Technology

[0002] Argon arc welding (argon arc welding), a welding method using argon as the shielding gas, holds an irreplaceable position in numerous fields such as machinery manufacturing, aerospace, chemical equipment, and pressure vessels due to its significant advantages, including stable arc, high weld quality, and small heat-affected zone. Its core principle is to use the electric arc generated between the tungsten electrode and the workpiece as a heat source, utilizing the protective layer formed by argon gas to isolate the weld area from air and prevent oxidation, thereby obtaining a high-quality weld joint. It is particularly suitable for welding easily oxidized materials such as stainless steel, aluminum alloys, and titanium alloys.

[0003] The existing technology has the following problems: Generally, it is difficult to adjust the angle between the body and handle of the argon arc welding torch, which makes it difficult to respond flexibly to diverse work requirements. This not only affects the operating efficiency but also reduces the welding quality. In addition, the common argon arc welding torch adopts an L-shaped design, which is not convenient for storage and further increases the inconvenience of carrying it.

[0004] Therefore, this utility model provides an argon arc welding torch to solve the above problems. Utility Model Content

[0005] This invention provides an argon arc welding torch, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: including a fixed plate and an adjustment structure assembled inside the fixed plate, and a movable structure assembled on one side of the outside of the fixed plate, wherein the gun body is mounted on the other side of the outside of the fixed plate; The adjustment structure includes a cylinder penetrating the surface of a fixed plate and a spring fixedly connected to the inner wall of the cylinder, as well as a movable cylinder slidably connected to the surface of the cylinder. A buffer rod is sleeved inside the spring, and a sliding plate is fixedly connected to one end of the spring. The sliding plate penetrates both sides of the cylinder and is fixedly connected to the inner wall of the movable cylinder. The surface of the fixed plate at one end of the movable cylinder has a plurality of limiting holes arranged in a circular array. Three limiting rods that are adapted to the limiting holes are fixedly connected to one end of the movable cylinder near the fixed plate.

[0007] As a preferred technical solution of this application, the surface of the fixing plate is provided with a circular hole for the cylinder to rotate, the inner wall of the circular hole is provided with a limiting groove, and a limiting ring fixedly connected to the surface of the cylinder is slidably connected inside the limiting groove.

[0008] As a preferred technical solution of this application, the cylinder has a cavity inside for the spring to move in, the other end of the spring is fixedly connected to the inner wall of the cavity, and rectangular grooves are formed on both sides of the cylinder surface for the sliding plate to slide in, the rectangular grooves communicating with the cavity.

[0009] As a preferred technical solution of this application, a fixing ring is fixedly connected to the end of the cylinder away from the movable cylinder, and the inner wall of the fixing ring is fixedly connected to the gun body.

[0010] As a preferred technical solution of this application, the movable structure includes a sleeve that is slidably connected to one side of the surface of the fixed plate, a threaded ring that is rotatably connected to the surface of the sleeve, and a threaded block that is fixedly connected to the inner wall of the fixed plate and threadedly connected to the threaded ring.

[0011] As a preferred technical solution of this application, a baffle is fixedly connected to one end of the sleeve, a rubber pad is fixedly connected to the surface of the sleeve, and a rotating groove for the threaded ring to rotate is provided at the end of the baffle and the rubber pad that are close to each other.

[0012] As a preferred technical solution of this application, a circular groove for housing the gun body is provided on one side of the surface of the sleeve, the circular groove penetrates the sleeve, and T-shaped grooves are provided on both sides of the surface of the sleeve, and T-shaped blocks that are fixedly connected to both sides of the surface of the fixing plate are slidably connected inside the T-shaped grooves.

[0013] Compared with the prior art, the beneficial effects of this utility model are: By adjusting the structure, when the gun body angle needs to be adjusted, pulling the movable cylinder causes its inner sliding plate to slide along the cylindrical rectangular groove, compressing the spring and buffer rod inside the cavity, causing the limit bar to disengage from the limiting hole of the fixed plate. At this time, the cylinder can rotate within the circular hole of the fixed plate, and the limiting ring slides along the limiting groove to ensure stability. The fixed ring then drives the gun body to be adjusted to the required angle. Releasing the movable cylinder causes the spring to reset and push the sliding plate, allowing the limit bar to re-engage into the limiting hole, thus fixing the angle. In addition, the sliding of the movable cylinder can also adjust the gun body extension length to adapt to the operating distance requirements of different welding scenarios. In multi-angle welding of complex components, this can reduce hand twisting, reduce fatigue, and improve welding efficiency.

[0014] By setting up the movable structure, the gun body can be adjusted to the same level as the sleeve, with the gun head located at one end of the cylinder. Rotating the threaded ring, it connects with the threaded block on the inner wall of the fixed plate, causing the T-shaped block on the surface of the fixed plate to slide along the T-shaped groove on the surface of the sleeve. This allows the gun head to enter the sleeve first, making the device straight, which is convenient for storage and carrying, prevents the gun head from being bumped, and improves the service life of the device.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This utility model provides, for example Figure 1-5 The argon arc welding gun shown includes a fixed plate 1, an adjustment structure 2 assembled inside the fixed plate 1, a movable structure 3 assembled on one side of the outside of the fixed plate 1, and a gun body 4 mounted on the other side of the outside of the fixed plate 1. The adjustment structure 2 includes a cylinder 201 penetrating the surface of the fixed plate 1 and a spring 202 fixedly connected to the inner wall of the cylinder 201, and a movable cylinder 203 slidably connected to the surface of the cylinder 201. A buffer rod is sleeved inside the spring 202. A sliding plate 204 is fixedly connected to one end of the spring 202. The sliding plate 204 penetrates both sides of the cylinder 201 and is fixedly connected to the inner wall of the movable cylinder 203. The surface of the fixed plate 1 at one end of the movable cylinder 203 has several limiting holes arranged in a circular array. Three limiting rods 205 that are adapted to the limiting holes are fixedly connected to one end of the movable cylinder 203 near the fixed plate 1.

[0019] Using the above scheme, when the angle of the gun body 4 needs to be adjusted, the movable cylinder 203 is pulled, and the sliding plate 204 on its inner wall slides along the rectangular groove on the surface of the cylinder 201, compressing the spring 202 and buffer rod in the cavity, causing the limiting rod 205 at the end of the movable cylinder 203 to disengage from the limiting hole on the surface of the fixed plate 1. At this time, the cylinder 201 can rotate within the circular hole of the fixed plate 1, and the limiting ring on the surface slides along the limiting groove to ensure smooth rotation. Then, the fixed ring 206 drives the gun body 4 to be adjusted to the required angle. After the movable cylinder 203 is released, the spring 202 returns to its original position and pushes the sliding plate 204, causing the limiting rod 205 to re-engage into the corresponding limiting hole, thus completing the angle fixation. At the same time, the sliding of the movable cylinder 203 can also adjust the extension length of the gun body 4 to adapt to the operating distance requirements in different welding scenarios. Especially in multi-angle welding of complex components, it can reduce the twisting of the operator's hands, reduce fatigue, and improve welding efficiency.

[0020] The surface of the fixed plate 1 has a circular hole for the cylinder 201 to rotate. A limiting groove is formed on the inner wall of the circular hole. A limiting ring is slidably connected to the inside of the limiting groove and fixedly connected to the surface of the cylinder 201. A cavity is formed inside the cylinder 201 for the spring 202 to move. The other end of the spring 202 is fixedly connected to the inner wall of the cavity. Rectangular grooves are formed on both sides of the surface of the cylinder 201 for the sliding plate 204 to slide. The rectangular grooves communicate with the cavity. A fixing ring 206 is fixedly connected to the end of the cylinder 201 away from the movable cylinder 203. The inner wall of the fixing ring 206 is fixedly connected to the gun body 4. The movable structure 3 includes a sleeve 301 slidably connected to one side of the surface of the fixed plate 1 and a rotating connecting... A threaded ring 302 is attached to the surface of the sleeve 301, and a threaded block 303 is fixedly connected to the inner wall of the fixing plate 1 and threadedly connected to the threaded ring 302. A baffle 304 is fixedly connected to one end of the sleeve 301, and a rubber pad 305 is fixedly connected to the surface of the sleeve 301. The baffle 304 and the rubber pad 305 have a rotating groove for the threaded ring 302 to rotate at their respective ends. The fixing plate 1 passes through the threaded ring 302. A circular groove for the gun body 4 to be housed is opened on one side of the surface of the sleeve 301. The circular groove passes through the sleeve 301. T-shaped grooves are opened on both sides of the surface of the sleeve 301. T-shaped blocks 306 that are fixedly connected to both sides of the surface of the fixing plate 1 are slidably connected inside the T-shaped grooves.

[0021] Using the above scheme, the gun body 4 is adjusted to the same level as the sleeve 301, with the gun head located at one end of the cylinder. Rotating the threaded ring 302, it is threadedly connected to the threaded block 303 on the inner wall of the fixing plate 1, causing the T-shaped block on the surface of the fixing plate 1 to slide along the T-shaped groove on the surface of the sleeve 301, so that the gun head of the gun body 4 enters the interior of the sleeve 301 first. This makes the device linear, easy to store and carry, avoids damage to components such as the nozzle and tungsten electrode due to collision, and extends its service life. The baffle 304 and rubber pad 305 at one end of the sleeve 301 can provide a comfortable grip fulcrum for the operator. The flexible contact of the rubber pad 305 reduces the pressure of holding for a long time, which is in line with ergonomic design.

[0022] The working principle of an argon arc welding torch according to an embodiment is as follows: When the angle of the torch body 4 needs to be adjusted, the movable cylinder 203 is pulled outward. The sliding plate 204 on the inner wall of the movable cylinder 203 slides along the rectangular groove on the surface of the cylinder 201 away from the fixed plate 1. At the same time, the spring 202 and the buffer rod in the cavity of the cylinder 201 are compressed, causing the three limiting rods 205 at the end of the movable cylinder 203 near the fixed plate 1 to disengage from the limiting holes on the surface of the fixed plate 1. At this time, the cylinder 201 can rotate freely in the circular hole of the fixed plate 1. The limiting ring on the surface of the cylinder 201 slides along the limiting groove on the inner wall of the circular hole to ensure smooth rotation. Then, the fixed ring 206 at the end of the cylinder 201 drives the torch body 4 to rotate and adjust to the required welding angle. After the angle is determined, the movable cylinder 203 is released, the spring 202 resets under the action of elastic force, pushes the sliding plate 204 to move the movable cylinder 203 towards the fixed plate 1, and causes the limiting rods 205 to re-engage into the corresponding limiting holes, thus completing the angle fixation. If it is necessary to adjust the extension length of the gun body 4, the movable cylinder 203 can be pulled or pushed directly. The sliding plate 204 slides along the rectangular groove to change the relative position of the movable cylinder 203 and the cylinder 201, thereby adjusting the extension length of the gun body 4 from the fixed plate 1 to adapt to the operating distance requirements of different welding scenarios. Next, the gripping and storage operations are performed. During welding, rotating the threaded ring 302 causes the sleeve 301 to slide along the surface of the fixed plate 1. Since the threaded ring 302 is threadedly connected to the threaded block 303 on the inner wall of the fixed plate 1, the sleeve 301 slides along the surface of the fixed plate 1. The T-slots on both sides of the sleeve 301 move along the T-blocks of the fixed plate 1, allowing the circular groove on the surface of the sleeve 301 to align with the position of the gun body 4, and the gun body 4 extends out from the circular groove. The operator grips the rubber pad 305 on the surface of the sleeve 301. The baffle 304 prevents the hand from slipping, and the flexible contact of the rubber pad 305 enhances grip comfort, conforms to ergonomic design, and facilitates stable operation. When storage or carrying is required, first adjust the gun body 4 to the same horizontal position as the sleeve 301 by adjusting the adjustment structure 2, ensuring that the gun head faces the end of the sleeve 301. Then, rotate the threaded ring 302 in the opposite direction to drive the sleeve 301 to slide towards the gun body 4, so that the gun head of the gun body 4 gradually enters the inside of the sleeve 301 until most of the gun body 4 is stored in the circular groove. At this time, the device is in a straight line, which reduces the space occupied and makes it easy to carry. At the same time, the sleeve 301 protects the gun head and prevents the nozzle, tungsten electrode and other components from being damaged by collision. After use, if you need to adjust the welding angle or length again, repeat the above adjustment steps. If you need to use it again, rotate the threaded ring 302 to reset the sleeve 301, and the gun body 4 will extend to perform the welding operation.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. 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.
