Abstract
Description
Technical Field
[0001] This utility model relates to the field of welding torch technology, specifically to a welding torch with an adjustable barrel. Background Technology
[0002] A welding torch is the part used in the welding process to perform the welding operation. It is a tool used for gas welding, shaped like a gun, with a nozzle at the front that sprays out a high-temperature flame as a heat source. It is flexible, convenient, quick, and the process is simple.
[0003] Existing gas shielded welding torches generally suffer from the design flaw of non-adjustable barrels. This is particularly problematic in narrow, confined spaces or when welding irregularly shaped components. Traditional fixed torches are difficult to operate due to limited angle adjustment, often requiring frequent changes of different barrel specifications or unconventional welding postures. This not only reduces work efficiency but also leads to unstable weld quality and inaccurate heat-affected zone control. For example, the prior art, represented by the prior art document "An Adjustable Gas Shielded Welding Torch Barrel" (application number: 202120243041.9), addresses this issue by incorporating a flexible metal hose in the middle of a curved section on the gas shielded welding torch. This allows the torch to be rotated to the most suitable position for different needs, facilitating more convenient operation. Furthermore, the contact nozzle and protective sleeve at the front of the torch offer various combinations, allowing for the replacement of different lengths of contact nozzle and protective sleeve sets as needed. This effectively solves the problems of the existing technology. However, its structure still requires improvement, as detailed below:
[0004] Although the solution includes an adjustable metal bend to adjust the length and angle of the welding torch barrel, the device requires manual adjustment of the barrel. When welding is in progress, manual adjustment poses a safety hazard if the barrel needs to be adjusted. The device cannot automatically adjust the barrel, resulting in poor practicality.
[0005] Therefore, a welding torch with an adjustable barrel is needed to improve the above-mentioned problems. Utility Model Content
[0006] The purpose of this invention is to provide a welding torch with an adjustable barrel to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] An adjustable barrel welding torch includes a welding torch body, a welding torch switch is provided on the outer wall of the welding torch body, a connecting tube is provided at one end of the welding torch body, and a barrel is provided at the other end of the welding torch body, wherein the barrel is made of a stretchable metal corrugated pipe material, and a welding torch nozzle is provided at one end of the barrel.
[0009] The outer wall of the welding torch body is provided with a first spherical section, an electric control cylinder is installed on the outer wall of the first spherical section, a second spherical section is installed at one end of the electric control cylinder, a welding torch nozzle is connected to one end of the second spherical section, and a control switch is embedded in the outer wall of the welding torch body.
[0010] As a preferred embodiment of this utility model, the control switch is connected to an electrically controlled cylinder via a wire, and the connection method is an electrical connection, and the cross-section of the connecting pipe is a conical structure.
[0011] As a preferred embodiment of this utility model, the first spherical section is provided in multiple sets and is located on the outer wall of the welding torch body.
[0012] As a preferred embodiment of this utility model, the second spherical section is provided in multiple sets and is located on the outer wall of the welding torch nozzle.
[0013] As a preferred embodiment of this invention, the control switch is located on one side of the first spherical section.
[0014] As a preferred embodiment of this utility model, the electrically controlled cylinders are provided in multiple sets and are respectively located on one side of the gun barrel, and the multiple sets of electrically controlled cylinders form a ring structure.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. In this utility model, an electrically controlled cylinder in an adjustable welding torch is used. When the control switch is turned on, the electrically controlled cylinder pushes the welding torch nozzle with a thrust, causing the nozzle to move laterally. This causes the nozzle to extend the retractable metal corrugated tube of the torch, thus adjusting its length. Simultaneously, the control switch retracts one set of electrically controlled cylinders, resulting in a backward pulling force on the outer wall of the nozzle. Because the lengths of the multiple electrically controlled cylinders around the torch are inconsistent, the nozzle causes the torch to bend inward, facilitating the adjustment of the torch's curvature and length. This solves the problem of manual adjustment of the torch barrel, which poses safety hazards when manual adjustment is needed during welding. The device cannot automatically adjust the barrel, resulting in poor practicality. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0022] For examples, please refer to Figure 1-3 This utility model provides a technical solution:
[0023] An adjustable barrel welding torch includes a welding torch body 1, a welding torch switch 2 provided on the outer wall of the welding torch body 1, a connecting pipe 3 provided at one end of the welding torch body 1, and a barrel 4 provided at the other end of the welding torch body 1, wherein the barrel 4 is made of a retractable metal corrugated pipe material, and a welding torch nozzle 5 is provided at one end of the barrel 4.
[0024] A first spherical section 6 is provided on the outer wall of the welding torch body 1. An electric control cylinder 7 is installed on the outer wall of the first spherical section 6. A second spherical section 8 is installed at one end of the electric control cylinder 7. A welding torch nozzle 5 is connected to one end of the second spherical section 8. A control switch 9 is embedded in the outer wall of the welding torch body 1.
[0025] In this embodiment, please refer to Figure 1 , Figure 2 and Figure 3 When the control switch 9 is connected to the electric cylinder 7 via a wire and the connection is electrical, the device is energized, and the control switch 9 controls the electric cylinder 7 to operate. The cross-section of the connecting pipe 3 is conical. Multiple sets of first spherical sections 6 are provided and are located on the outer wall of the welding torch body 1. Multiple sets of second spherical sections 8 are provided and are located on the outer wall of the welding torch nozzle 5. The control switch 9 is located on one side of the first spherical section 6. Multiple sets of electric cylinders 7 are provided and are located on one side of the torch barrel 4. The multiple sets of electric cylinders 7 form a ring structure.
[0026] The working process of this utility model is as follows: When using the adjustable barrel welding torch designed in this scheme, the device is energized by the control switch 9, which is connected to the electric cylinder 7 via a wire. This energizes the control switch 9, causing the electric cylinder 7 to operate. Simultaneously, a first spherical section 6 is provided on the outer wall of the welding torch body 1, and the electric cylinder 7 is mounted on its outer wall. A second spherical section 8 is mounted on one end of the electric cylinder 7, and one end of the second spherical section 8 is connected to the welding torch nozzle 5. With the control switch 9 embedded in the outer wall of the welding torch body 1, simply turning on the control switch 9 activates the electric cylinder 7. When the electric cylinder 7 operates, one end of the electric cylinder 7 pushes the welding torch nozzle... The nozzle 5 applies a thrust, causing one end of the nozzle 5 to move laterally. This causes the nozzle 5 to extend the retractable corrugated metal barrel 4, thus adjusting its length. Simultaneously, the control switch 9 controls one set of electrically controlled cylinders 7 to retract, resulting in a backward pulling force on one side of the outer wall of the nozzle 5. Since the lengths of the multiple sets of electrically controlled cylinders 7 around the barrel 4 are inconsistent, the nozzle 5 causes the barrel 4 to bend inward, facilitating the adjustment of the barrel's curvature and length. This solves the problem of manually adjusting the barrel when welding is in progress, which poses certain safety hazards. The device cannot automatically adjust the barrel, resulting in poor practicality.
[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
