Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning pipeline welding, in particular to automobile air-conditioning pipeline welding equipment. Background Art

[0002] The automobile air-conditioning system provides the automobile with functions such as cooling, heating, defrosting and defogging. There are multiple pipeline structures in the automobile air-conditioning system. Different pipelines and components are usually connected by pipeline joints. The pipeline joints are also called pipeline pressure plates. One end of the pressure plate is welded to the air-conditioning pipe, and the other end of the pressure plate is connected to the expansion valve, compressor and other air-conditioning system components. The traditional welding method is manual welding, which is time-consuming, labor-intensive and of low quality.

[0003] In the related art, reference can be made to the Chinese utility model patent with authorization announcement number CN217122057U, which discloses a welding tool for automobile air-conditioning pipes, including a base plate and a support frame. Clamping mechanisms are arranged on both sides of the top of the base plate. The base plate is provided with a driving mechanism and a welding mechanism. When the motor is started, the screw is driven to rotate, thereby driving the two clamping half rings to tightly clamp the welded parts. The four clamping members respectively clamp different parts to be welded. When the second electric telescopic rod is started, the distance between the two parts to be welded can be adjusted to make them contact, so as to facilitate welding of the welded parts. When the driving motor rotates, it drives the driving gear to rotate, and then drives the hollow gear to rotate, and drives the welded parts to rotate. When the first electric telescopic rod is extended or retracted, the distance between the arc welding head and the welded parts can be adjusted. After the arc welding head is energized, the welded parts can be welded.

[0004] The air-conditioning pipe is a tubular structure, and the two ends of the pipe pressure plate are inconsistent in size. Therefore, the clamping effect of the pipe pressure plate using the clamping half ring is reduced, resulting in a deviation in the welding angle between the air-conditioning pipe and the pipe pressure plate during welding, which in turn makes it impossible to install the air-conditioning system, resulting in an increase in the defective rate, increasing production costs, and reducing the welding efficiency of the automotive air-conditioning pipe.
