[0002] In the production and actual application of flanges, it is crucial to ensure the accurate measurement of flange apertures, which is not only related to the factory quality of flanges, but also the key to ensuring their safe and effective operation in actual working conditions. However, the current detection of flange apertures generally relies on traditional micrometer measurement methods.

[0003] When using a micrometer to detect the flange aperture, workers usually need to manually adjust the micrometer to adapt to different aperture sizes, and after the detection is completed, manually read and record the detected aperture value again. This manual operation method is not only time-consuming and labor-intensive, but also reduces the detection efficiency. It may also increase the measurement error due to human factors. For this reason, we propose a flange aperture detection device. Summary of the invention

[0033] A vertical rod 7 is fixedly provided at the bottom of the mounting rod 3, a supporting spring 8 is fixedly provided at the top of the vertical rod 7, a sleeve 9 is movably sleeved on the outside of the vertical rod 7, the mounting rod 3 passes through the sleeve 9, and the top of the supporting spring 8 abuts against the sleeve 9, and the positioning detection mechanism 4 is arranged on the outside of the sleeve 9.

[0034] The positioning detection mechanism 4 includes a telescopic arm 41 fixedly arranged on the outside of the sleeve 9. The telescopic arm 41 is a self-locking telescopic arm 41 in the prior art. The telescopic arm 41 can move along the sleeve 9 on the outside of the vertical rod 7. A placement block 42 is fixedly arranged at the end of the telescopic arm 41, and a control rod 43 is movably arranged on the placement block 42. A connecting plate 44 is fixedly arranged at the bottom of the control rod 43, and a laser detector 45 and a positioning cone 46 are respectively arranged at both ends of the connecting plate 44. The laser detector 45 is the prior art, which includes a handle and a detection head and a display screen arranged at the bottom and top of the handle. The detection head is used to penetrate into the inside of the hole for laser detection, and the display screen is used to read numbers.

[0035] A positioning screw 47 is threadedly provided on the connecting plate 44 , a positioning cone 46 is fixedly provided at the bottom end of the positioning screw 47 , and a handle is provided at the top end of the positioning screw 47 , and the positioning cone 46 can be driven to move up and down by rotating the positioning screw 47 .

[0036] During inspection, first move the telescopic arm 41 to drive the positioning cone 46 to move above the hole position, then rotate the positioning screw 47 to drive the positioning cone 46 to move into the hole. At this time, the hole position can be centered, and then the positioning cone 46 is moved out, and then the control rod 43 is pulled up to drive the positioning cone 46 and the laser detector 45 to move, and at the same time, the control rod 43 is rotated 180 degrees so that the laser detector 45 is aligned with the hole position at this time, and then the hole position can be measured by the laser detector 45.

[0037] A positioning frame 48 is fixedly provided on the placement block 42, and a positioning block 49 is fixedly provided on the outer side of the control rod 43. The positioning block 49 is plugged into and matched with the positioning frame 48.

The positioning arc plate 12 is rotatably connected to the fastening screw 11, and the inner end surface of the positioning arc plate 12 abuts against the outer side of the sleeve 9. Rotating the fastening screw 11 drives the inner end surface of the positioning arc plate 12 to be close to the sleeve 9, which can limit the sleeve 9 and prevent it from rotating, thereby ensuring stable measurement of the laser detector 45.

[0040] The engraving assembly 6 includes an extension plate 61 fixedly arranged on the outer side of the sleeve 9, a push rod 62 is movably arranged on the extension plate 61, the push rod 62 movably penetrates the extension plate 61 and a push block 63 is fixedly connected to the bottom end, a pull button is fixedly connected to the top end of the push rod 62, and a connecting spring 64 is arranged on the outer side of the push rod 62, and the two ends of the connecting spring 64 are respectively in contact with the extension plate 61 and the pull button, and pressing the pull button can drive the push block 63 to move downward;

[0041] The bottom of the sleeve 9 is also fixedly provided with an engraving plate 65, on which a notch for use with the top block 63 is provided, and an ink cartridge 66 is provided at the bottom of the engraving plate 65, and a compression spring 67 is provided between the ink cartridge 66 and the engraving plate 65, and the two ends of the compression spring 67 are respectively fixedly connected to the engraving plate 65 and the ink cartridge 66, the ink cartridge 66 is hollow inside and contains ink, and a cotton strip 68 is embedded at the bottom of the ink cartridge 66, and when the cotton strip 68 moves downward, it can print a line on the detection disk 54;

[0042] When the top block 63 moves downward, it can squeeze the ink cartridge 66 to make it move downward, thereby causing the cotton strip 68 to leave a line on the detection disk 54 .

[0043] An insert block 13 is fixedly provided at the bottom of the detection disk 54, a plug hole 14 is opened in the fixed block 53, and a limit screw 15 is threadedly provided on the outer side of the fixed block 53. The end of the limit screw 15 close to the fixed block 53 is rotatably connected to the limit block 16, and the limit block 16 slides through the fixed block 53 and the end thereof abuts against the outer wall of the insert block 13. Rotating the limit screw 15 can drive the limit block 16 to move and abut against the insert block 13, thereby limiting the insert block 13.

[0044] In summary, when in use, first use the chuck 2 to position the flange, then use the positioning cone 46 to position the first hole to be inspected, and then position the sleeve 9 after positioning, and then rotate the inspection disk 54 to align any scale line of the inspection disk 54 with the cotton strip 68, and then use the laser detector 45 to detect. When inspecting the next hole, the sleeve 9 will rotate a certain angle, driving the ink cartridge 66 to rotate, and after using the positioning cone 46 to position the next hole again, press the pull button to make the cotton strip 68 print lines on the inspection disk 54 again, and so on. When the remaining holes are inspected one after another, lines corresponding to the number of holes are also printed on the inspection disk 54. Since the number of scale lines is the same as the number of holes and the scale lines are evenly distributed, it is only necessary to observe whether the lines on the inspection disk 54 coincide with the scale lines to determine whether the hole positions are evenly distributed. No additional measurement readings are required, and the ink lines on the inspection disk 54 can be erased for the next use.

[0045] Embodiment 2:
