Description

Technical Field

[0001] The present invention relates to the technical field of fin tube production, and more particularly to a detection mechanism for high-efficiency fin tubes. Background Art

[0002] Finned tubes are widely used in various applications requiring heat exchange, such as air conditioners, refrigerators, and radiators. In air conditioning systems, finned tubes are typically used in condensers and evaporators to achieve heat exchange between air and refrigerant. During the production of high-efficiency finned tubes, the outer surface of the finned inner tubes needs to be sheathed with corresponding aluminum tubes, which are then used to form the fins. The strength and quality of the finned inner tubes will affect the subsequent use of the finned tubes, so the finned inner tubes need to be tested accordingly to ensure the quality of the subsequent finned tubes.

[0003] According to the search, the patent with patent number CN214373925U discloses a workbench, both sides of the top of the workbench are fixedly connected with support plates, the tops of the two support plates are fixedly connected with a top plate, the middle part of the bottom surface of the top plate is fixedly connected with a hydraulic cylinder, the bottom end of the hydraulic cylinder is fixedly connected with a connecting plate, a pressure plate is arranged below the connecting plate, and a buffer mechanism for buffering the pressure plate is arranged between the pressure plate and the connecting plate. The pressure plate is driven downward by the extension and contraction of the hydraulic cylinder. Since the pipeline body is supported by the support block, when the pressure plate contacts the pipeline body, the return spring buffers the pressure plate, so that the pressure of the pressure plate on the pipeline body is slowly released to avoid damage to the pressure sensor caused by excessive instantaneous pressure. The pipeline body is subjected to the pressure applied by the pressure plate and released to the pressure sensor, so that the strength of the pipeline body can be detected.

[0004] With respect to the above-mentioned related technologies, the detection mechanism of the existing technology is usually in the above-mentioned state. Although the above-mentioned detection mechanism can realize the press detection of the pipeline, during the detection process, several positions on the outer surface of the pipeline are usually selected, and then single-point detection is performed. Since it is a single position on the outer surface of the pipeline for detection, it is not easy to discover the strength problems caused by the production process in other positions of the pipeline, resulting in incomplete detection of the pipeline. Unqualified pipelines flowing into the market will affect the quality of subsequent products. For this reason, a detection mechanism for high-efficiency finned tubes is proposed.

[0034] The following is combined with Figure 1-8 The present invention is described in further detail.

[0035] See also Figure 1-8 A detection mechanism for high-efficiency fin tubes includes a main body module 100 and a pressure detection module 200. The main body module 100 includes a bottom plate 110. A movable groove 120 is opened on the top of the bottom plate 110.

A first cylinder 160 is installed on one side of the bottom plate 110, and the output shaft of the first cylinder 160 is connected to the other mounting bracket 130. Next, the pressure detection module 200 includes an expansion frame 210 that is slidably connected to the inside of the movable groove 120, a pressure component 220 is provided on the top of the expansion frame 210, and two first balls 230 are movably connected to the inner wall of the expansion frame 210.
