[0015] The present invention will be further explained and described below with reference to the accompanying drawings and embodiments.

[0016] like Figure 1 and Figure 2 As shown, this utility model discloses a copper pipe inner diameter detection device. A servo module 5 is mounted on a frame 4. A lifting block 6 is slidably connected to the front of the servo module 5. A sensor fixing rod 3 is fixed to the front of the lifting block 6. A gob gauge floating detection sensor 10 is installed at the front end of the sensor fixing rod 3. A gob gauge rod fixing plate 11 is fixed to the front of the lifting block 6, located below the sensor fixing rod 3. A through hole is opened in the middle of the gob gauge rod fixing plate 11, and the gob gauge rod 1 is placed in the through hole. The gob gauge floating detection sensor 10 is located above the gob gauge rod 1. A product placement fixture 8 is fixed directly below the gob gauge rod 1, and a copper pipe 7 is placed on the product placement fixture 8. The product placement fixture 8 is fixed to a fixed bracket 9 directly below. The servo module 5 is electrically connected to a PLC control system. An alarm device is also fixed on the frame 4, and the alarm device is electrically connected to the detection sensor 10 via a signal line.

[0017] Working process: This device is controlled by a PLC control system. After the copper tube 7 is placed on the product placement fixture 8, the PLC control system issues a command to drive the servo module 5 to drive the lifting block 6 downward, which in turn drives the gauge rod fixing plate 11 and the sensor fixing rod 3 downward. When the inner diameter of the copper tube is qualified, the gauge rod 1 normally enters the copper tube 7. When the inner diameter of the copper tube is not qualified, the outer wall of the copper tube will push the gauge rod 1 up. The pushed-up gauge rod 1 blocks the gauge float detection sensor 8, causing the device to alarm.

[0018] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative rather than restrictive in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing explanations and descriptions. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. Furthermore, no reference numerals in the claims should be construed as limiting the scope of the claims.
