[0002] Wind turbine flanges are flanges for wind turbine generator sets. The ring blank of the flange can be processed and formed by a ring rolling machine. Ring rolling is a process that uses a ring rolling machine to produce continuous local plastic deformation of the ring. Through this process, the wall thickness of the ring can be reduced, the diameter can be increased, and the cross-sectional profile can be formed.

[0003] After the ring blank is formed, it is necessary to measure whether the dimensions of the ring blank meet the standards. The existing method is to manually measure the inner and outer diameters and thickness of the ring blank using calipers.

The second supports 232 are installed on one side inside the movable frame 23, so that the driven shaft 261 is rotatably mounted on the second supports 232, so that the driven shaft 261 can only rotate on the second supports 232 and cannot move left or right. Driven bevel gears 262 at both ends of driven shaft 261 mesh with driving bevel gear 29. Both sides of driven shaft 261 are threadedly connected to movable rods 264. The end of movable rod 264 away from driven shaft 261 is connected to inner diameter contact plate 263 by long bolt 265. A second spring 266 is also sleeved between the long bolt 265 and the inner diameter contact plate 263. Both sides of the bottom of movable frame 23 are provided with slide grooves 231. The inner diameter contact plate 263 is slidably disposed in the slide grooves 231 of movable frame 23.

When the two inner diameter contact plates 263 are in contact with the inner side of the ring blank, the inner diameter of the ring blank is obtained by measuring the distance between the two inner diameter contact plates 263 and adding the thickness of the two inner diameter contact plates 263. The driven shaft 261 has two opposite threads on its two sides, and the two movable rods 264 are respectively provided with threaded holes that mate with the two opposite threads, so that the two movable rods 264 are threadedly connected to the driven shaft 261.

S3. When the output shaft of the hydraulic push rod 241 extends, it drives the rack 27 to move. The rack 27 drives the two spur gears 281 and the drive shaft 28 to rotate. One drive shaft 28 drives the movable frame 23 to move down through the thread, and the other drive shaft 28 drives the drive bevel gear 29 to rotate. S4. When the movable frame 23 moves down, it will drive the thickness contact plate 252 and the inner diameter contact plate 263 to move down together. At the same time, the active bevel gear 29 drives the driven bevel gear 262 and the driven shaft 261 to rotate. The movable rod 264 moves outward along the driven shaft 261 through the thread. Then, the movable rod 264 drives the inner diameter contact plate 263 to move outward along the slide groove 231 until the inner diameter contact plate 263 contacts the inner side of the ring blank and compresses the second spring 266. The thickness contact plate 252 contacts the top of the ring blank and compresses the spring telescopic rod 251. S5. The distance between the two outer diameter contact plates 244 is measured by the outer diameter laser measuring instrument 245 to obtain the outer diameter of the ring blank.

The distance between the thickness contact plate 252 and the conveyor belt 12 is measured by the thickness laser measuring instrument 253 to obtain the thickness of the ring blank. After the ring blank size measurement is completed, the hydraulic push rod 241 is activated to retract the output shaft and reset the outer diameter contact plate 244, inner diameter contact plate 263 and thickness contact plate 252 for the next round of measurement.
