Description

Technical Field

[0001] This utility model relates to the field of tube expansion testing, and in particular to a device for checking the tube expansion accuracy of a vertical tube expander. Background Technology

[0002] In the production and application of vertical tube expanders, tube expansion accuracy is a key factor in ensuring the overall performance and operational quality of the equipment. Tube expansion accuracy directly affects the heat exchange efficiency, sealing performance, and service life of the heat exchanger. Therefore, accurate detection of tube expansion accuracy is of utmost importance.

[0003] Existing vertical tube expander precision inspection typically involves placing the tube expander on a conveyor belt and transporting it to the testing equipment for inspection. However, during the inspection process, some areas of the expander are in contact with the conveyor belt, making it difficult to achieve comprehensive precision inspection. This can easily lead to missed detections, affecting the accuracy of the inspection. Furthermore, during processing, some dust and other impurities can easily adhere to the expander. If not cleaned in time, this can easily cause inaccurate inspections and errors, further reducing inspection efficiency and accuracy.

[0004] Therefore, it is necessary to design a vertical tube expander accuracy inspection device that can automatically clean tubes of different sizes while rotating the tubes to achieve comprehensive and accurate detection, reduce missed detections, improve detection efficiency and accuracy, and enhance versatility.

[0022] like Figures 1-3As shown, the clamping assembly includes an electric push rod 2, a lifting frame 3, a conventional motor 4, a first roller 5, a rotating frame 6, a torsion spring 7, and a second roller 8. The electric push rod 2 is connected to the middle of the support frame 1. The electric push rod 2 and the processor are electrically connected through a control module. The lifting frame 3 is connected to the telescopic end of the electric push rod 2. The lifting frame 3 is slidably connected to the support frame 1.

[0024] When precision inspection of the expanded tube is required, this device can be used.

Under the action of the thread, the sliding frame 11 moves and resets, thereby driving the detector 12 to move and reset. The detector 12 then reciprocates to perform precision testing on the expansion tube.
