Description

Technical Field

[0001] The utility model relates to the technical field of filter element welding, in particular to a multifunctional filter element welding tool. Background Art

[0002] At present, filter element welding usually requires the use of multiple independent tooling, including ventilation and anti-oxidation tooling, coaxiality assurance tooling, and height assurance tooling. These tooling are relatively complicated to install and operate, which increases the difficulty of welding debugging and affects production efficiency. In addition, existing welding tooling usually cannot take into account both ventilation and anti-oxidation and coaxiality assurance, resulting in unstable welding quality. At the same time, the height adjustment method is relatively single, and the adjustment accuracy is low, which is not conducive to adapting to filter elements of different specifications. Due to the risk of oxidation during the welding process, most of the existing technologies use a separate protective gas ventilation device, and it is impossible to achieve an integrated tooling design.

[0003] At present, there are some patent technologies that have optimized the filter element welding tooling. For example, patent publication number CN118810045B proposes a vertical multi-station filter element welding machine. The device adopts a multi-station structure to achieve hot melt welding of handle plates, filter elements and other components, thereby improving welding efficiency; although the above technology has been optimized in terms of welding accuracy and adaptability, it still has certain limitations. The existing metal melt filter element welding protection tooling fails to effectively take into account the height adjustment function, resulting in a limited scope of application. Therefore, there is still a need for an integrated, compact and easy-to-operate multifunctional filter element welding tooling to simultaneously meet the requirements of anti-oxidation, coaxiality assurance and height adjustment during the welding process. Utility Model Content

It is easy to operate and can be used for welding filter elements of other different heights, which can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a multifunctional filter element welding tool, including a bracket, a height adjustment shaft and a vent nozzle, the bracket is arranged as a U-shaped structure, threaded holes are respectively arranged on both sides of the bracket, the threaded holes at both ends are located at the same horizontal height and have consistent size and coaxiality requirements, the center hole of the vent nozzle is arranged as a ventilation duct, the height adjustment shaft is arranged as a solid structure, the vent nozzle and the height adjustment shaft are respectively threadedly connected to the vent nozzle, the inner end of the vent nozzle and the inner end of the height adjustment shaft are respectively provided with a left boss and a right boss, the filter element is arranged between the left boss and the right boss, and the left boss and the right boss are respectively matched with the small clearance of the inner hole at both ends of the filter element.

[0006] Furthermore, the other end of the ventilation nozzle is connected to a ventilation hose for supplying air, the other end of the ventilation hose is connected to an air tank, and the other end of the ventilation nozzle is configured as an outer inclined cone.

[0007] Furthermore, the left boss and the right boss are connected to the vent nozzle and the height adjustment shaft respectively by means of threads.

[0008] Furthermore, the height adjustment shaft is provided with scale marks, and a hexagonal adjustment portion is provided at the right end of the height adjustment shaft.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] Through integrated design, ventilation and anti-oxidation, coaxiality guarantee and height adjustment functions are integrated into one, reducing the need for the use of multiple independent tooling, thereby simplifying the operation process and improving production efficiency. The vent nozzle and height adjustment shaft use coaxial cylindrical bosses, which match the small gap in the inner hole of the filter element to ensure coaxiality during welding and improve welding quality and stability.

[0011] There is a ventilation pipe inside the vent nozzle, which continuously introduces protective gas during the welding process to effectively prevent oxidation and improve the reliability of welding. The height adjustment shaft adopts a threaded structure, which can accurately adjust the height of the welding filter element and is suitable for filter elements of different sizes.
