Description

Technical Field

[0001] The utility model relates to the technical field of welding tooling, in particular to a welding and fixing device for an air-conditioning pipe silencer. Background Technique

[0002] With the rapid development of modern technology, air-conditioning equipment has become an indispensable part of our daily life. However, during the operation of air-conditioning equipment, due to the flow of air and the movement of mechanical components, noise is often generated, which not only affects the comfort of users but also may cause interference to the surrounding environment. Therefore, it is particularly important to perform noise reduction treatment on air-conditioning equipment.

[0003] As a key component for reducing the noise of air-conditioning equipment, the welding quality of the air-conditioning pipe silencer directly affects the noise reduction effect and service life. In the prior art, most of them adopt the lapping method or high-frequency welding. Each time, only a single interface can be welded, and only in batches can its cost be guaranteed. However, for welding at different angles, the mold needs to be replaced multiple times, or multiple devices are required to complete the welding. The equipment has a large volume, requires a large space, and has a large investment, resulting in the inability to ensure the accuracy of the product inspection fixture. Moreover, the high voltage of the high-frequency current loop is harmful to both the human body and the equipment, with high maintenance costs, easy damage, and higher power consumption costs compared to flame brazing. Content of the Utility Model
