[0014] The present invention can preliminarily detect the outer diameter of the ring through the first laser measuring head and the second laser measuring head, and then detect the inner diameter and roundness through the measuring device, which not only meets the function of radial measurement, but also can detect the side and roundness status of the ring, thereby greatly increasing the functionality and practicality of the device and further reducing the production cost. The design of multiple groups of stickers can increase the accuracy of the device in measuring the side wall of the ring. When the sticker rotates along the side wall of the ring, when the thickness of the surface of the ring is inconsistent, it can be reflected by the movement of the probe on the sensor block. When there is no problem, the probe will not move on the sensor block. The use of the damper ensures the stability of the spring, prevents it from vibrating easily, and further increases the accuracy of the device. BRIEF DESCRIPTION OF THE DRAWINGS

After the distance measurement is completed, the stopper 3 is driven to move outward by starting the hydraulic cylinder 34. When the stopper 3 moves to the outermost side, the telescopic assembly 8 is started to make the telescopic assembly 8 drive the two groups of measuring devices 14 to extend. Then, the two groups of measuring devices 14 are driven to move down a certain distance by starting the lifting cylinder 37, so that the bottom of the measuring device 14 fits with the top surface of the material plate 28.

The initial length of the first electric telescopic rod 11 is recorded as K. The distance between the upper end face of the L-shaped mounting plate 12 and the middle position of the two sets of second electric telescopic rods 13 is N, and is entered into the interactive panel 4. The telescopic assembly 8 is first moved so that the two sets of measuring devices 14 are respectively located on the inner and outer sides of the side wall of the ring. Then, the thickness of the ring is determined by starting the first electric telescopic rod 11 and the second electric telescopic rod 13. Then, one of the sets of second electric telescopic rods 1 3, thereby determining the stroke of the other group of second electric telescopic rods 13, making the strokes of the two groups of second electric telescopic rods 13 equal, so that the connection point of the two groups of second electric telescopic rods 13 is located in the middle of the top surface of the ring, at this time, the distance from the center of the ring to the middle of the thickness of the ring is obtained, and the length K of the first electric telescopic rod 11 itself, the length J of the connecting plate, and the stroke H of the second electric telescopic rod 13 are known, and then the distance between the central axis of the first motor 9 and the center of the ring can be calculated at this time, and then by driving the telescopic assembly 8, the first electric telescopic rod 11 is synchronously extended to the same length, so that the central axis of the first motor 9 is aligned with the center of the ring.

Enter the production size Z of the ring through the interactive panel, then place the ring to be tested on the material plate, start the third motor, the third motor drives the bidirectional screw to rotate, thereby driving the nut sleeve to move, and further drives the rotating roller on the installation frame to move inward, so that the distance between the rotating rollers on the two sets of installation frames is Z+2mm; S2, by starting the second motor, the second motor drives the threaded rod to rotate, thereby driving the slider to move in the slide slot, further driving the push column to move, thereby driving the ring to move to the stopper and fit with the stopper, at this time, the ring is preliminarily screened, when the ring can enter, the next step of detection is carried out, when the ring cannot enter, it means that the size is unqualified; S3, after the ring and the stopper are fitted, the first laser measuring head and the second laser measuring head work to measure the distance between the mounting block and the stopper as A, the distance between the mounting block and the outer wall of the ring as B, and the diameter of the flange as C, where C=AB; S4. After the distance measurement is completed, the stopper is driven to move outward by starting the hydraulic cylinder. When the stopper moves to the outermost side, the telescopic assembly is started to drive the two sets of measuring instruments to extend. Then, the lifting cylinder is started to drive the two sets of measuring instruments to move down a certain distance so that the bottom of the measuring instrument fits with the top surface of the material plate. Then, the first electric telescopic rod is started to drive the measuring instrument away from the center of the ring to move toward the outer wall of the ring, and the stroke G is recorded. The measuring instrument stops when the induction block works. Then, a second electric telescopic rod is started to drive another set of measuring instruments to move toward the inner wall of the ring, and the stroke F is recorded. The measuring instrument stops when the induction block works. At this time, the third laser measuring head works, and the spacing between the two side blocks on the measuring instrument is obtained as D.

S5, then reset half of the stroke of the second electric telescopic rod, specifically F / 2, and at the same time, the stroke of the first electric telescopic rod is also extended by F / 2, so that the sticker on the inner measuring device is again fitted with the inner wall of the ring, and then another set of second electric telescopic rods is started, and its stroke is also F / 2, and at the same time, the sticker on the outer measuring device is fitted with the outer wall of the ring. At this time, the strokes of the two sets of second electric telescopic rods are equal, both F / 2, and the actual moving stroke of the first electric telescopic rod is H, where H=G-(F / 2), and at this time, the centers of the two sets of measuring devices are located in the middle of the thickness of the ring, and the distance between the center of the two sets of measuring devices and the center of the circle is ( E / 2)+(D / 2), when the length J from the connection position of the connecting block and the first electric telescopic rod to the central axis of the first motor, the initial length K of the first electric telescopic rod, and the distance N from the connection position of the upper end surface of the L-shaped mounting plate and the first electric telescopic rod to the middle position of the two sets of second electric telescopic rods are known, the distance M that the telescopic assembly needs to move again can be calculated, so that the central axis of the first motor is located directly above the circle of the ring, where M=(E / 2)+(D / 2)-(J-H+K+N), and the first electric telescopic rod is synchronously extended by a distance of M, so that the position of the measuring device does not change, thereby achieving the purpose of locating the center of the rings of different sizes; S6.
