Description

Technical Field

[0001] This utility model relates to the field of welding and cutting assembly technology, and in particular to a welding and cutting assembly with an adjustable cutting nozzle angle. Background Technology

[0002] The welding and cutting assembly includes an oxy-fuel cutting torch, a tool that uses the high-temperature combustion of oxygen and fuel gas to cut metal. The principle of an oxy-fuel cutting torch is to heat the metal using the high-temperature combustion of oxygen and fuel gas, and then use high-pressure oxygen to blow away the heated metal, thus achieving the purpose of cutting the metal. Specifically, the fuel gas and oxygen mix and burn inside the cutting nozzle, producing a high-temperature flame. The flame preheats the metal above its ignition point, causing it to oxidize and produce oxides. Then, the high-pressure oxygen stream blows away the molten oxide slag, forming a cut. Simultaneously, the released heat further preheats the next layer of metal, bringing it to its melting point, continuing the cutting process.

[0003] During the welding and cutting process, the cutting nozzle angle needs to be manually adjusted for cutting. However, adjusting the cutting nozzle angle usually requires certain skills and experience. Novices or operators who have not been fully trained may find it difficult to master the technique accurately, and the angle may be inconsistent each time, resulting in unstable cutting quality. Utility Model Content

A flexible gas tube is mounted on the bottom of the mounting joint, and a mounting ring is provided at the other end of the flexible gas tube. The mounting ring and the flexible gas tube are connected and fixed by multiple fixing components. Fixed extension seats are symmetrically mounted on both sides of the mounting joint.

[0007] A cavity is provided in the fixed extension seat on one side of the mounting joint. A drive motor is placed in the cavity. The output end of the drive motor is connected to a fixed shaft. The other side of the fixed shaft is connected to a mounting ring. A limit shaft is installed on the other side of the mounting ring at the fixed shaft. The other end of the limit shaft is connected to the fixed extension seat through a bearing. A cutting nozzle body is placed in the mounting ring. A limit component is screwed into the mounting ring above the cutting nozzle body.

[0008] Furthermore, in a preferred configuration, a first mounting ring is mounted on the outer side of the top of the mounting ring, and a second mounting ring is mounted on the outer side of one side of the flexible air tube. Multiple mounting holes are equally spaced through the first and second mounting rings.

[0009] Furthermore, in a preferred configuration, the top of the mounting ring has a cavity, the diameter of which is larger than that of the cutting nozzle body, and the inner wall of the cavity has an external thread.

[0010] Furthermore, in a preferred configuration, the limiting component includes a limiting pressure ring, and a connecting ring is mounted on the top of the limiting pressure ring, the connecting ring being T-shaped.

[0012] In addition, a preferred structure is that T-shaped limiting sliders are symmetrically installed on both sides of the mounting ring below the fixed shaft, one side of the T-shaped limiting slider is limited and slidably disposed in the fixed extension seat, and an arc-shaped sliding cavity is opened in the fixed extension seat at the T-shaped limiting slider.

[0013] The beneficial effects of this utility model are as follows:

[0020] Reference Figure 1-3An adjustable cutting nozzle welding and cutting assembly includes an oxy-gas cutting gun body 1, which includes a mounting connector 11. A flexible gas tube 3 is mounted on the bottom of the mounting connector, and a mounting ring 4 is provided at the other end of the flexible gas tube 3. The mounting ring 4 and the flexible gas tube 3 are connected and fixed by multiple fixing components. Fixed extension seats 2 are symmetrically mounted on both sides of the mounting connector 11. It is worth noting that the specific structure, working principle, and connection method of the oxy-gas cutting gun body 1 and the mounting connector 11 are all existing technologies that are currently disclosed in the market and are not the main technical problems to be solved in this utility model. Therefore, they will not be described in detail in this utility model. At the same time, the fixing components are fixing bolts and fixing nuts, which are threadedly connected. The specific structure, working principle, and connection method of the fixing bolts and fixing nuts are all existing technologies that are currently disclosed in the market and are not the main technical problems to be solved in this utility model. Therefore, they will not be described in detail in this utility model.

[0021] Furthermore, a cavity is provided in the fixed extension seat 2 on one side of the mounting connector 11, and a drive motor 6 is placed in the cavity. The output end of the drive motor 6 is connected to a fixed shaft. The other side of the fixed shaft is connected to the mounting ring 4, and a limit shaft is installed on the other side of the mounting ring 4 at the fixed shaft. The other end of the limit shaft is connected to the fixed extension seat 2 through a bearing. A cutting nozzle body 5 is placed in the mounting ring 4, and a limit assembly 8 is screwed into the mounting ring 4 above the cutting nozzle body 5.

[0022] Furthermore, a first mounting ring is installed on the outside of the top of the mounting ring 4, and a second mounting ring is installed on the outside of one side of the flexible air tube 3. Multiple mounting holes are equally spaced inside the first and second mounting rings.

[0023] Meanwhile, the top of the mounting ring 4 has a cavity, the diameter of which is larger than that of the cutting nozzle body 5, and the inner wall of the cavity has an external thread.

[0024] Furthermore, the limiting component includes a limiting pressure ring, and a connecting ring is installed on the top of the limiting pressure ring. The connecting ring is T-shaped.

[0026] Specifically, by rotating the inner thread of the limiting pressure ring and the mounting ring 4, the cutting nozzle body 5 is pressed against, ensuring the stability of the cutting nozzle body 5 after installation.

[0027] Furthermore, T-shaped limiting sliders 7 are symmetrically installed on both sides of the mounting ring 4 below the fixed shaft. One side of the T-shaped limiting slider 7 is limited and slidably disposed in the fixed extension seat 2, and an arc-shaped sliding cavity is opened in the fixed extension seat 2 at the T-shaped limiting slider.

[0028] In this embodiment, the drive motor 6, mounting ring 4, flexible air tube 3 and gas cutting gun body 1 are designed to ensure the normal use of the cutting nozzle while it is being installed, and the cutting nozzle can be adjusted within a certain range. This allows the operator to flexibly adjust the tilt angle of the cutting nozzle according to different cutting needs, thus enhancing the cutting flexibility of the cutting nozzle.

[0029] Meanwhile, when the mounting ring 4 is rotated by the drive motor 6, the stability of the mounting ring 4 during rotation is ensured by the T-shaped limit slider 7, and the stability of the cutting nozzle body 5 during rotation is also ensured.

[0030] When the cutting nozzle body needs to be replaced, the mounting ring 4 and the flexible air tube 3 are separated. Then, the mounting ring 4 is rotated at a certain angle by the drive motor 6, and the thread of the limiting component is loosened and removed, so that the cutting nozzle body 5 can be disassembled and replaced.

[0031] In this invention, the drive motor 6, mounting ring 4, flexible air tube 3, and gas cutting gun body 1 are designed to ensure the normal use of the cutting nozzle while it is being installed.
