Water-cooled welding torch with easy replacement of nozzle

Abstract

This utility model relates to the field of welding torch technology, specifically disclosing a water-cooled welding torch that facilitates nozzle replacement. It includes a torch body with a limiting member on its outer surface. The limiting member has an installation nozzle inside. The limiting member includes a housing with two cavities inside. Each cavity is connected to a set of first springs. Each set of first springs has a limiting plate connected to its right end, and each limiting plate has a limiting ring connected to its right side. Pulling the ring causes the limiting ring and the inclined block to move. As the limiting ring and inclined block move, the first springs are compressed, causing the inclined block to contact the limiting block. The limiting block then enters the groove through a second spring, allowing for quick nozzle removal. Releasing the ring pushes the limiting ring and inclined block, and a new nozzle can then be inserted to complete the replacement. This achieves rapid nozzle replacement and solves the problem of low nozzle replacement efficiency.

Description

Technical Field

[0001] This utility model relates to the field of welding torch technology, and specifically discloses a water-cooled welding torch with an easy-to-replace nozzle. Background Technology

[0002] A welding torch is a tool used for welding operations. Its main function is to convert electrical energy into heat energy during the welding process, thereby melting the welding wire and penetrating it to the part that needs to be welded. The design of the welding torch makes it very flexible, convenient and quick to use, and the welding process is relatively simple. With the high current and high voltage provided by the welding machine, the welding torch can generate enough heat at the end to complete the welding task.

[0003] The welding torch nozzle serves as a protective mechanism for the welding torch head. However, the nozzles currently used are typically installed by twisting them for assembly and disassembly. This installation method is low and requires workers to repeatedly twist the nozzle during assembly and disassembly. Therefore, a water-cooled welding torch that facilitates nozzle replacement is needed to solve this problem. Utility Model Content

[0004] This invention proposes a water-cooled welding gun with an easy-to-replace nozzle. Through the movement and contact of the inclined block and the limiting block, the nozzle body can be quickly engaged and disassembled, solving the problem of inconvenient nozzle replacement.

[0005] This utility model is implemented as follows: a water-cooled welding gun with an easy-to-change nozzle includes a gun body. The outer surface of the gun body is provided with a limiting member. An installation nozzle is provided inside the limiting member. The limiting member includes a shell. The shell has two cavities inside. A set of first springs is connected inside each cavity. A limiting plate is connected to the right end of each set of first springs. A limiting ring is connected to the right side of each limiting plate. An inclined block is connected to the side of the two limiting rings that are close to each other. A pull ring is connected to the side of the two limiting rings that are far apart from each other. Two through grooves are provided on the outer surface of the shell.

[0006] As a preferred embodiment of the present invention, a water-cooled welding gun with an easy-to-replace nozzle, the mounting nozzle includes a nozzle body, a sealing ring is connected inside the nozzle body, two grooves are formed on the outer surface of the nozzle body, a second spring is connected inside each of the two grooves, and a limit block is connected to one end of each of the two second springs that is far apart from each other.

[0007] As a preferred embodiment of this utility model of a water-cooled welding gun that facilitates nozzle replacement, the interior of the outer shell is connected to the outer surface of the gun body, and the outer surface of the limiting ring is slidably connected to the inner wall of the cavity.

[0008] As a preferred embodiment of this utility model of a water-cooled welding gun that facilitates nozzle replacement, the outer surface of the limiting block is slidably connected to the inner wall of the groove, and the interior of the nozzle body is located inside the outer shell.

[0009] As a preferred embodiment of this utility model of a water-cooled welding gun that facilitates nozzle replacement, the interior of the sealing ring is in contact with the outer surface of the gun body.

[0010] The beneficial effects of this utility model are: This water-cooled welding torch, which facilitates nozzle replacement, allows for quick nozzle change by pulling a pull ring. Pulling the pull ring moves a limiting ring and a wedge block. As the limiting ring and wedge block move, they compress a first spring, causing the wedge block to contact the limiting block. This allows the limiting block to enter the groove via a second spring, enabling rapid nozzle removal. Releasing the pull ring allows the first spring to push the limiting ring and wedge block to move, and then inserting a new nozzle body completes the replacement. This achieves rapid nozzle replacement and solves the problem of low nozzle replacement efficiency. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0015] Please see Figure 1-4 A water-cooled welding gun with easy nozzle replacement includes a gun body 1. A limiting member 2 is provided on the outer surface of the gun body 1. An installation nozzle 3 is provided inside the limiting member 2. The limiting member 2 includes a housing 201. Two cavities 202 are opened inside the housing 201. A set of first springs 203 is connected inside each cavity 202. A limiting plate 204 is connected to the right end of each set of first springs 203. A limiting ring 205 is connected to the right side of each limiting plate 204. An inclined block 206 is connected to the side of the two limiting rings 205 that are close to each other. A pull ring 207 is connected to the side of the two limiting rings 205 that are far apart from each other. Two through grooves 208 are opened on the outer surface of the housing 201.

[0016] In this embodiment, the cooperation between the limiting member 2 and the mounting nozzle 3 enables efficient and rapid installation and disassembly, increasing the efficiency and convenience of nozzle replacement. The first spring 203, with its elasticity and extensibility, can move the limiting ring 205 and the inclined block 206 according to external pressure.

[0017] As a technical optimization of this utility model, the mounting nozzle 3 includes a nozzle body 301, a sealing ring 302 is connected inside the nozzle body 301, two grooves 303 are opened on the outer surface of the nozzle body 301, a second spring 304 is connected inside the two grooves 303, and a limit block 305 is connected to one end of each of the two second springs 304 that is far apart from each other. The interior of the outer shell 201 is connected to the outer surface of the gun body 1, and the outer surface of the limit ring 205 is slidably connected to the inner wall of the cavity 202.

[0018] In this embodiment, the sealing ring 302 can increase the sealing between the nozzle body 301 and the gun body 1.

[0019] As a technical optimization of this utility model, the outer surface of the limiting block 305 is slidably connected to the inner wall of the groove 303, the inside of the nozzle body 301 is located inside the outer shell 201, and the inside of the sealing ring 302 is in contact with the outer surface of the gun body 1.

[0020] In this embodiment: the cooperation of the limiting block 305 and the groove 303 can ensure the stability of the limiting block 305 when it moves, and the nozzle body 301 is located inside the outer shell 201 and is fitted onto the outer surface of the gun body 1.

[0021] The working principle and usage process of this utility model are as follows: In use, first pull the pull ring 207. The pull ring 207 will move the limiting ring 205 and the inclined block 206. As the limiting ring 205 moves, it will compress the first spring 203. Simultaneously, the inclined block 206 will contact the inclined surface of the limiting block 305, causing the limiting block 305 to be compressed against the second spring 304, thus allowing the limiting block 305 to enter the groove 303. Then, holding the nozzle body 301 allows for disassembly. During installation, release the pull ring 207, and the first spring... Spring 203 will not be under pressure and will push the limiting ring 205 and the inclined block 206 to reset. Then, the nozzle body 301 is inserted into the inside of the housing 201. Due to the inclined design of the limiting block 305, it will contact the inside of the housing 201 and be under force, squeezing the second spring 304 into the groove 303. Finally, after the nozzle body 301 is inserted into the inside of the housing 201, the limiting block 305 will be aligned with the inside of the limiting ring 205. At the same time, the second spring 304 will not be under force and will push the limiting block 305 into the limiting ring 205.
