Description

Technical Field

[0001] The utility model relates to the technical field of air conditioner silencer processing equipment, and specifically discloses a welding device for processing air conditioner silencers. Background Art

[0002] An air conditioner silencer is a device used to reduce the noise generated during the operation of an air conditioner system. Its main function and principle are to use components such as sound-absorbing materials, reflecting plates, and impedance tubes to absorb, reflect, and interfere with sound waves, thereby reducing the noise generated during the operation of the air conditioner system. The air conditioner silencer is usually installed at the inlet and outlet of the air conditioner to effectively reduce the impact of noise on the indoor environment and improve comfort. During the production of the air conditioner silencer, it is necessary to use an air conditioner silencer welding or pressing device to weld the connecting pipe to the air conditioner silencer body to form a complete air conditioner silencer. The Chinese patent with the patent number CN213730215U discloses an air conditioner silencer fixed-point pressing device, including a bottom plate. Four corners of the top of the bottom plate are fixedly connected with sliding rods. The top of the sliding rods is fixedly connected with a top plate. The bottom of the sliding rods is slidably connected with a placement plate. A hydraulic cylinder is arranged on the top of the bottom plate. The hydraulic cylinder is fixedly connected with the placement plate. A base is fixedly connected to the top of the placement plate. A silencer is arranged on the top of the base. A limiting groove is opened on the top of the base. The silencer is adapted to the limiting groove. First fixing blocks and second fixing blocks are respectively fixedly connected to both sides of the top of the placement plate. Through the arranged limiting part, cylinder, cross bar and other structures, the utility model can limit the silencer, prevent it from tilting, shaking, etc. during the welding and pressing process, thus affecting the pressing effect, and has a good limiting effect, greatly improving the working precision. However, during the use of the above device, workers need to manually place the air conditioner silencer body and the connecting pipe to be welded into the device. The working state of the workers is extremely likely to affect the welding efficiency, and it is not safe enough, reducing the automation degree of the device. Moreover, the device is not convenient for the transfer operation before and after the welding of the air conditioner silencer. Therefore, to solve the above problems, the utility model proposes a welding device for processing air conditioner silencers. Summary of the Utility Model
