[0025] As shown in Figures 1 to 5 A metal hose joint welding device, comprising: a rack 1, a transmission assembly 2, a clamping assembly 4;

[0026] For a long time, small caliber metal hoses for stoves have been using traditional simple welding positioning tool for open welding. The end of the plastic-coated corrugated pipe is sleeved into the clamping ring, and then aligned with the welding pipe of the joint assembly. The welding gun position is adjusted manually to start arc, rotate the corrugated pipe body to realize ring welding. This traditional welding method has low production efficiency and unstable welding quality.

[0027] The transmission assembly 2 is composed of a transmission belt 21, a support plate 22, a fixed rod 23, a mounting plate 24, and a pressing wheel 25. The transmission belt 21 is placed on the top of the rack 1. The support plate 22 is slidably connected with the fixed rod 23. The fixed rod 23 is rotatably connected with the pressing wheel 25. The pressing wheel 25 is rotatably connected with the mounting plate 24. The fixed rod 23 is rotatably connected with the mounting plate 24. The transmission belt 21 is placed on the top of the rack 1 as a power or motion transmission medium. When the external power source (such as a motor) drives the transmission belt 21, the transmission belt 21 will move along the top of the rack 1, thereby transmitting the metal hose. Then, the fixed rod 23 and the pressing wheel 25 are rotatably connected. The pressing wheel 25 can rotate around the fixed rod 23. This design allows the pressing wheel 25 to produce rotational motion when subjected to external forces. The rotation of the pressing wheel 25 can be used for pressing, rolling, or guiding, etc., to limit and press the metal hose;

[0028] In addition, the pressing wheel 25 is also rotatably connected with the mounting plate 24. This design increases the flexibility of the pressing wheel 25, allowing it to maintain a certain degree of freedom on the mounting plate 24. This degree of freedom allows the pressing wheel 25 to more flexibly adapt to different working environments or operational requirements when subjected to external forces;

[0029] Finally, the fixed rod 23 and the mounting plate 24 are also rotatably connected. This design allows the fixed rod 23 to rotate relative to the mounting plate 24, thereby further increasing the flexibility and adaptability of the transmission assembly 2. By adjusting the relative position or angle between the fixed rod 23 and the mounting plate 24, the transmission assembly 2 can be optimized in layout and performance in different working environments.

[0030] The clamping assembly 4 is composed of a mounting shell 41, a limiter 42 fixedly installed on the mounting shell 41, and a centering assembly 43.

[0031] The centering assembly 43 comprises a first clamping plate 431, a first rack 432 slidingly installed in the first clamping plate 431, a gear 433 engaged with the first rack 432, a second rack 434 engaged with the other side of the first gear 433, a limiting plate 435 fixedly installed on the surface of the second rack 434, a collet 436 fixedly installed on the end of the second rack 434, a second clamping plate 437 fixedly installed on the surface of the mounting shell 41, a sliding groove is formed in the second clamping plate 437 for the sliding of the limiting plate 435, and the gear 433 is rotatably connected with the second clamping plate 437. The top of the first rack 432 is provided with a driving motor, and the output end of the driving motor is fixedly connected with the first rack 432. When it is necessary to adjust the position of the collet 436, the driving motor can be used to drive the first rack 432 to drive the gear 433 to rotate, thereby driving the second rack 434 to move in the opposite direction. Due to the sliding action of the limiting plate 435 in the sliding groove, the second rack 434 can move smoothly and drive the collet 436 to the desired position. The centering assembly 43 can accurately adjust the position of the collet 436, so that the metal hose is clamped to the position reached by the collet 436;

[0032] In addition, the bottom end of the first rack 432 is provided with the collet 436, and the gear 433, the second rack 434 and the limiting plate 435 are all mirror-imaged with two groups along the center line of the short side of the first rack 432, and the bottom end of the second rack 434 is obliquely inclined to the first rack 432. The bottom of the second rack 434 is not directly perpendicular to the first rack 432, but is obliquely arranged towards the direction of the first rack 432. This oblique arrangement is used to make the two groups of mirror-imaged second racks 434 move in the opposite direction along the first rack 432 when the first rack 432 is pushed downward, and the three groups of racks all move towards the same center, thereby clamping the metal hose at the center and keeping the metal hose at the center position to ensure the accuracy during welding.

[0033] The side edge of the clamping assembly 4 is also provided with a welder 5, which comprises a guide rail 51, a first welding plate 52 and a second welding plate 53. The guide rail 51 is slidingly connected with the first welding plate 52, and the guide rail 51 is slidingly connected with the second welding plate 53. The hole diameter of the welding hole in the first welding plate 52 is smaller than that of the welding hole in the second welding plate 53. The first welding plate 52 can slide on the guide rail 51, so that its position can be adjusted. The first welding plate 52 can freely move along the axis direction of the guide rail 51. The guide rail 51 is slidingly connected with the second welding plate 53. Similarly, the second welding plate 53 can also slide on the guide rail 51 to adjust its position.

[0034] As a supplement: the diameter of the welding hole opened on the first welding plate 52 is smaller than the diameter of the welding hole opened on the second welding plate 53. This design can be used to adapt to welding materials of different diameters or achieve different welding effects. For example, a smaller hole diameter can be used for fine welding or to limit the flow of welding material, while a larger hole diameter can be used to accommodate larger welding materials or provide a wider welding area to facilitate the convenience of welding different materials by the metal hose welding machine arm 6, and finally welding the metal hose to ensure the flexibility of welding.

[0035] Working principle:

[0036] The transmission belt 21 is placed on the top of the rack 1 as a power or motion transmission medium. When the external power source (such as a motor) drives the transmission belt 21, the transmission belt 21 will move along the top of the rack 1, thereby transmitting the metal hose, and then the fixed rod 23 is rotationally connected between the pressing wheel 25. The pressing wheel 25 can rotate around the fixed rod 23, which allows the pressing wheel 25 to produce rotational motion when subjected to external force. When it is necessary to adjust the position of the chuck 436, the first rack 432 can be driven by the driving motor to drive the gear 433 to rotate, thereby driving the second rack 434 to move in the opposite direction. Due to the sliding action of the limiting plate 435 in the sliding groove, the second rack 434 can move smoothly and drive the chuck 436 to the desired position. When the first rack 432 is pushed downward, the second rack 434 moves in the opposite direction of the first rack 432, and the three sets of racks move towards the same center, thereby centering the metal hose and keeping the metal software in the center position to ensure the accuracy of welding.

The contents not described in detail in the specification belong to the existing technology known to those skilled in the art.
