[0002] Welded flanges are common components for connecting pipes. They typically have a center hole surrounded by bolt holes. Before leaving the factory, the flanges undergo hole size inspection to ensure proper dimensional accuracy and facilitate seamless connection between flanges.

Summary of the Invention

[0016] A power supply box is located on the right side of the internal detection mechanism of the cabinet, and the battery and power management module are located inside the power supply box.

[0017] A method for detecting the hole dimensions of a welded flange includes the following steps:

[0018] S1, Fixed flange;

[0019] S2, Exposure;

[0020] S3, Record light spot information;

[0021] S4. Read and analyze the light spot information.

[0022] Step S1 further includes the following sub-steps:

[0023] S1.1 Flange leveling;

[0024] S1.2 Lens leveling.

[0025] Preferably, the recorded light spot information in step S3 includes the shape, size, and brightness distribution information of the light spot formed after the light passes through the flange center hole and the connection hole, as well as the intensity and illumination area of ​​the light reflected from the flange surface.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] 1. In the use of this invention, the level of the lens is adjusted by controlling the lifting of one or two of the leveling electric cylinders. The level of the lifting plate is detected by the angle sensor installed at the bottom of the connecting cylinder. When the lifting plate is not in a level state, the leveling electric cylinder on the corresponding side is adjusted by the controller to adjust the level of the lifting plate, thereby ensuring that the lens is perpendicular to the ground of the housing, that is, parallel to the light source bracket.

[0028] 2. In use, the controller starts the propulsion cylinder, which pushes the rotating slide closer to the flange. The rotating slide moves the flange support, and the flange support moves the photosensitive plate two through the vertical plate, pressing the photosensitive plate two tightly against the flange. This allows light to pass through the center hole of the flange and the fixing holes around the center hole and directly illuminate the photosensitive plate two, forming a light spot on the photosensitive plate two. The controller reads the light spot information on the photosensitive plate two and compares it with preset light spot information. When the detected light spot size is smaller than the preset light spot size, it means that the hole size is smaller than the normal size; conversely, it is larger than the normal size. Thus, the hole size of the flange can be quickly determined.

[0029] 3. In the use of this invention, during the exposure process, some of the light that shines on the flange surface passes through the hole, and some is reflected by the flange surface. Since the size of the lens is not smaller than the size of the flange to be tested, the reflected light returns to the electric light source after passing through the lens, that is, the focal point of the lens, and does not hit the photosensitive plate one, or only a small amount hits it. If the surface of the flange is not flat, the reflected light is not horizontal. The reflected light from the uneven surface may be upward or downward. The photosensitive plate three outside the lens can receive a large amount of light shining on the outside of the lens, and the photosensitive plate one can receive a large amount of light that is biased towards the center of the lens. The controller reads the information of the photosensitive plate one and the photosensitive plate three, and can then determine the flatness of the flange surface.

[0030] 4. The method invented can not only detect the size of the hole, but also the smoothness and flatness of the flange surface, ensuring the sealing of the flange connection; in addition, it can not only detect the size of the hole, but also the shape of the hole, because the shape of the hole will also affect the shape and size of the light spot irradiated on the photosensitive plate.

[0057] Please see Figure 9 A method for detecting the hole dimensions of a welded flange, comprising the following steps:

[0058] S1, Fixed flange;

[0059] S2, Exposure;

[0060] S3, Record light spot information;

[0061] S4. Read and analyze the light spot information.

[0062] Step S1 also includes the following sub-steps:

[0063] S1.1 Flange leveling;

[0064] S1.2 Lens leveling.

[0065] The recorded light spot information in step S3 includes the shape, size, and brightness distribution of the light spot formed after light passes through the flange center hole and connection hole, as well as the intensity and illumination area of ​​the light reflected from the flange surface.

[0066] Working principle: Before the exposure step, the center of the light source and the center of the lens 1232 are aligned on the same horizontal line. This can be achieved by controlling the leveling cylinder 12342 via the controller 126. The height of the lens 1232 is adjusted by simultaneously raising and lowering the two leveling cylinders 12342. When the two leveling cylinders are raised and lowered, they drive the lifting plate 12343 to rise and fall. The lifting plate 12343 drives the lens clamping groove 12344 to rise and fall, thereby raising and lowering the lens 1232.

[0067] The level of lens 1232 is adjusted by controlling the lifting of one or both of the two leveling electric cylinders 12342. The level of lifting plate 12343 is detected by angle sensor 12346 installed at the bottom of connecting cylinder 12345. When lifting plate 12343 is not level, the leveling electric cylinder 12342 on the corresponding side is adjusted by controller 126 to adjust the level of lifting plate 12343, thereby ensuring that lens 1232 is perpendicular to the ground of the housing, that is, parallel to the light source bracket 1211.

[0068] Similarly, in order to ensure that the light shines perpendicularly onto the surface of the flange to be inspected, the flange and lens 1232 must be kept parallel. The specific adjustment method is the same as the method of adjusting the horizontal position of lens 1232, and will not be described in detail here.

[0069] The focusing cylinder 1235 drives the lens slide 1233 to move left and right, thereby moving the lens and adjusting the focal length.

[0070] During testing, the controller 126 activates the push cylinder 1254, which pushes the rotating slide 1251 closer to the flange. The rotating slide 1251 moves the flange support 1242, which in turn moves the photosensitive plate 1253 via the vertical plate 12522, bringing the photosensitive plate 1253 close to the flange. This allows light to pass through the flange's center hole and the surrounding fixed holes, directly illuminating the photosensitive plate 1253 and forming a light spot. The controller 126 reads the light spot information on the photosensitive plate 1253 and compares it with preset light spot information. If the detected light spot size is smaller than the preset size, it indicates that the hole size is smaller than the normal size; conversely, it indicates that the hole size is larger than the normal size. This allows for rapid determination of the flange hole size.

[0071] The cross-sectional shape of the flange hole should be cylindrical. If the hole diameters on both sides of the flange are inconsistent, taking the hole diameter decreasing from left to right as an example, light rays parallel to the hole axis cannot pass through the hole smoothly. When passing the side with the smaller diameter, they will be blocked and reflected. The reflected light rays will be refracted in the direction of the hole axis, making the brightness of the photoelectric photoelectric material 1253 at the center greater than that at the edge. This can be used to determine whether the shape of the flange machining hole is regular.

[0072] Meanwhile, some of the light rays that hit the flange surface pass through the holes, while some are reflected off the flange surface. Since the size of the lens 1232 is not smaller than the size of the flange to be tested, the reflected light rays return to the electric light source after passing through the lens 1232, which is the focal point of the lens 1232, and do not hit the photosensitive plate 1213, or only a small amount of it. If the flange surface is uneven, the reflected light rays will not be horizontal. The reflected light rays from the uneven surface may be upward or downward. The photosensitive plate 1231 outside the lens 1232 can receive a large amount of light rays that hit the outside of the lens 1232, and the photosensitive plate 1213 can receive a large amount of light rays that are biased towards the center of the lens 1232. The controller 126 reads the information of the photosensitive plate 1213 and the photosensitive plate 1231 to determine the flatness of the flange surface.

[0073] The controller 126 controls the rotation coil 18 to be energized. After the rotation coil 18 is energized, the permanent magnet 17 rotates under the action of electromagnetic force. The permanent magnet 17 drives the block to rotate, and the rotating block 12427 drives the flange support cylinder 12421 to rotate. The flange support cylinder 12421 drives the flange with detection to rotate through the flange clamping groove 12424, which facilitates the detection of the other side surface of the flange.

[0074] The power management module 1302 converts the voltage and current of the battery 1301 into voltage and current suitable for the testing mechanism, and can provide emergency power to the testing mechanism in the event of a sudden power outage.
