The bottom surface of the connecting plate 34 is connected to the pressure plate 35.
[0027] When the clamping drive motor 33 is started, the driving end of the clamping drive motor 33 drives the lead screw to rotate, thereby causing the connecting plate 34 to move along the lead screw, thereby driving the pressing plate 35 to move, thereby achieving the clamping and releasing operations of the thin tube.
[0028] Furthermore, the clamping device 3 also includes an upper box body 31 and a clamping base 32. The bottom end of the upper box body 31 is rotatably connected to the top end of the clamping base 32. A cavity is provided in the upper box body 31.

This design facilitates the placement and removal of thin tubes.
[0030] The clamping member 37 is a latch-tensioning quick-action clamp.

The end surface of the lifting frame 23 extending from the support housing 21 is provided with the thickness gauge 24. The thickness gauge 24 is a micrometer thickness gauge with a resolution of 0.001mm, a measuring range of 0mm to 25.4mm, and a tolerance of no greater than 0.005mm. In the present invention, the thickness gauge 24 is made of ABS plastic and can be equipped with a push-type handle.

[0036] Working principle:
[0037] Thin tube clamping:
[0038] Open the clamping member 37 and flip the upper box body 31 upward around the hinge 36 to expose the placement area on the clamping base 32 .
[0039] Place the thin tube to be measured on the placement area of the clamping base 32 to ensure that the thin tube is properly positioned.

[0041] The clamping drive motor 33 is started, and the driving end of the clamping drive motor 33 drives the lead screw to rotate, so that the connecting plate 34 moves along the lead screw, and then drives the pressing plate 35 to move downward, stably clamping the thin tube between the pressing plate 35 and the clamping base 32.
[0042] Detection device adjustment:
[0043] According to the height of the thin tube and the measurement requirements, the detection drive motor 22 is started, and the driving end of the detection drive motor 22 drives the screw to rotate, so that the lifting frame 23 moves up and down along the slide groove of the support shell 21, and the height of the thickness gauge 24 is adjusted so that the thickness gauge 24 is in a suitable measurement position.
[0044] Thin pipe wall thickness measurement:
[0045] The detection device 2 is pushed to make the slider 41 slide on the slide rail 42, thereby driving the detection device 2 to move in the horizontal direction and moving the thickness gauge 24 to the measuring position of the thin tube.
[0046] The thickness gauge 24 is started to measure the wall thickness of the thin tube and record the measurement data.
[0047] Repeat the above steps to measure different positions of the thin tube to obtain comprehensive data on the wall thickness of the thin tube.
[0048] Thin tube removal:
[0049] After the measurement is completed, the clamping drive motor 33 is started to rotate in the reverse direction, thereby driving the pressing plate 35 to move upward and release the thin tube.
[0050] Open the clamping member 37, turn the upper box body 31 upward around the hinge 36, and take out the measured thin tube.
