Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Reference Figure 1-3, The utility model provides an embodiment: an adjustable inertia ring inspection tool, including a base mechanism 1, the base mechanism 1 includes a base plate 101, a No. 1 servo motor 103 is fixedly provided at the middle position of the upper end of the base plate 101, a fixing rod 104 is fixedly provided at the rear end of the base plate 101, a No. 3 mounting plate 109 is fixedly provided at the front position of the lower end of the fixing rod 104, an optical three-D surface profiler 110 is fixedly provided at the lower end of the No. 3 mounting plate 109 by screw thread, a No. 2 mounting plate 107 is fixedly provided at the middle upper end of the front end of the fixing rod 104, a display panel 108 is fixedly provided at the front end of the No. 2 mounting plate 107 by screw thread, a No. 1 mounting plate 105 is fixedly provided at the front position of the upper end of the fixing rod 104, and a lighting lamp 106 is fixedly provided at the lower end of the No. 1 mounting plate 105 by screw thread, a storage box 102 is slidably provided at the lower position of the front end of the base plate 101, and a record book 111 is movably provided inside the storage box 102;

[0026] Specifically, the base plate 101 facilitates the fixation of the No. 1 servo motor 103, which facilitates driving the detection plate 201 to rotate and adjust the detection position of the middle inertia ring. The fixing rod 104 facilitates the fixation of the No. 1 mounting plate 105, the No. 2 mounting plate 107 and the No. 3 mounting plate 109. The No. 1 mounting plate 105 facilitates the fixed installation of the lighting lamp 106, which provides good lighting conditions for the entire detection process, ensuring that the operator can clearly observe the operation status and the detection location. The No. 2 mounting plate 107 facilitates the fixed installation of the display panel 108, which facilitates the display of the detection data of the optical 3D surface profiler 110. The No. 3 mounting plate 109 facilitates the fixed installation of the optical 3D surface profiler 110. The optical 3D surface profiler 110 can perform high-precision detection of the surface profile of the inertia ring and collect relevant data, such as the surface flatness data information of the inertia ring. The storage box 102 facilitates the storage of the record book 111.

[0027] Reference Figure 3-4, a detection clamping mechanism 2 is fixedly provided on the upper end of the base mechanism 1, and the detection clamping mechanism 2 includes a detection plate 201, a No. 2 servo motor 202 is fixedly provided on one side of the detection plate 201, and a bidirectional threaded rod 203 is fixedly provided on the output end of the No. 2 servo motor 202, and a threaded box 204 is provided on the threaded sleeve on the outer surface of the bidirectional threaded rod 203. A clamping mechanism 205 is fixedly provided on the upper end of the two threaded boxes 204, and the two clamping mechanisms 205 include a fixed plate 20501. A No. 1 spring telescopic plate 20502 is fixed to the opposite outer side of the two fixed plates 20501 by a spring, and a No. 1 engraved plate is fixedly provided at the middle of the upper end of the detection plate 201 near the front and rear ends. A second spring telescopic plate 20503 is fixedly provided on the other side of the upper end of the two fixed plates 20501 through a spring. The fixed plate 20501, the first spring telescopic plate 20502 and the second spring telescopic plate 20503 are fixedly provided with a second scale line 20506 at the front and rear ends. A mounting rod 20505 is fixedly provided at the lower end of the two fixed plates 20501. An extension plate 20507 is fixedly provided on the other side of the front end of the two fixed plates 20501. A control screen 207 is fixedly provided on one side of the front end of the detection plate 201. A protective pad 20504 is fixedly provided on the other side of the two first spring telescopic plates 20502.

[0028] Specifically, after the second servo motor 202 is started, its output end drives the bidirectional threaded rod 203 to rotate. Since the outer surface of the bidirectional threaded rod 203 is threadedly sleeved with a thread box 204, under the action of the thread, as the bidirectional threaded rod 203 rotates, the two thread boxes 204 will move linearly in relative or opposite directions along the bidirectional threaded rod 203, thereby driving the clamp mechanism 205 fixed above to move, so as to adjust the distance between the two clamp mechanisms 205 so that it can adapt to inertia rings of different outer diameters. When the inertia ring is placed between the two clamp mechanisms 205, the fixed plate 20501, the first spring telescopic plate 20502 and the second spring telescopic plate 20503 are connected. Due to the structural characteristics of the spring connection, the spring will expand and contract accordingly according to the actual size of the inertia ring. For example, if the outer diameter of the inertia ring is slightly larger, the spring will be appropriately compressed, so that the No. 1 spring expansion plate 20502 and the No. 2 spring expansion plate 20503 are appropriately stretched outward, and at the same time, the inertia ring is tightly clamped by relying on the elastic force of the spring, and the protective pad 20504 can prevent damage to the surface of the inertia ring, ensuring that the clamping is firm and lossless. The setting of the No. 1 scale line 206 and the No. 2 scale line 20506 is conducive to detecting the outer diameter, inner diameter and thickness of the inertia ring when clamping it. It is quick, convenient and easy to use. The control panel 207 is conducive to controlling the opening and closing of the No. 2 servo motor 202.

[0029] Working principle: When the device is used, the second servo motor 202 is started to drive the bidirectional threaded rod 203 to rotate, thereby driving the clamping mechanism 205 to clamp and fix the middle inertia ring. After the inertia ring is firmly clamped by the clamping mechanism 205, the optical 3D surface profiler 110 can perform high-precision detection of the surface profile of the inertia ring and collect relevant data, such as surface flatness and dimensional accuracy of each part. It can also detect its outer diameter, inner diameter and thickness through the first scale line 206 and the second scale line 20506;

[0030] Secondly, the lighting lamp 106 provides good lighting conditions for the entire detection process. After the detection is completed, the operator can write the detection-related record information on the record book 111 in the storage box 102 for archiving, which is convenient for subsequent review and analysis.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
