The operation of the grinding mechanism 9 is controlled according to the pressure value of the pressure sensor. Disc springs 18 are fixedly installed between the multiple extrusion plates 32 and the sliding table 16 (when the disc spring 18 is subjected to impact load, it absorbs energy through its own deformation to suppress the vibration amplitude, and its damping characteristics are better than ordinary coil springs). A damping bearing 34 is rotatably installed in the sliding table 16, and a limiting groove 20 is provided in the damping bearing 34. The limiting block 6 is engaged in the limiting groove 20 for use.

[0037] The sliding table 16 is slidably mounted on the fixed plate 11, and a grinding table 12 is fixedly mounted on the sliding table 16. The steel ring 4 is placed on the grinding table 12 for grinding. A positioning structure is installed in the grinding table 12. The positioning structure is used to adaptively clamp steel rings 4 of different sizes and fix them in the grinding center position. The positioning structure includes a swivel 22 rotatably mounted on the upper end of the damping bearing 34, and a gear ring 2 30 is fixedly mounted on the outer side of the swivel 22. A rotating groove 21 is opened on the inner side of the swivel 22, and the guide rod 5 slides in the rotating groove 21 for use. A plurality of rotating shafts 31 are rotatably mounted in the grinding table 12, and a gear 2 29 is fixedly mounted on the plurality of rotating shafts 31, and each gear 29 is meshed with the gear ring 2 30. The upper end of each rotating shaft 31 Bevel gear 24 is fixedly installed on them, and a plurality of rotating grooves are provided on the grinding table 12, and threaded rods 19 are rotatably installed in the plurality of rotating grooves. A bevel gear 23 is fixedly installed on the ends of the plurality of threaded rods 19 close to each other, and each bevel gear 23 is meshed with the corresponding bevel gear 24. A plurality of sliding holes 13 are provided on the grinding table 12, and a nut is threadedly installed on the plurality of threaded rods 19, and each nut slides in the grinding table 12. A sliding column 33 is fixedly installed on the plurality of nuts, and a push plate 15 is fixedly installed on the upper end of the plurality of sliding columns 33. A rubber baffle 14 is fixedly installed on the side where the plurality of push plates 15 are away from each other. The rubber baffle 14 provides flexible clamping to avoid rigid damage and adapt to the curvature change of the inner wall of the steel ring 4.

[0038] At this time, the limit block 6 will be engaged in the limit groove 20, and then the guide rod 5 will enter the rotation groove 21 (the rotation groove 21 is set in a spiral shape). The resistance of the damping bearing 34 is greater than the sum of the friction between the bevel gear 1 23 and the bevel gear 2 24, the friction between the gear ring 2 30 and the multiple gears 2 29, and the friction between the multiple sets of nuts and the threaded rod 19. The guide rod 5 enters the rotation groove 21 to drive the rotating ring 22 to rotate. The rotation of the rotating ring 22 drives the multiple gears 29 to rotate through the gear ring 2 30, and the rotation of the multiple gears 29 drives the multiple rotating shafts 31 rotates, the rotation of multiple rotating shafts 31 drives multiple bevel gears 24 to rotate, the rotation of multiple bevel gears 24 drives multiple threaded rods 19 to rotate through multiple bevel gears 1 23, the rotation of multiple threaded rods 19 drives multiple nuts to move away from each other, the multiple nuts move through the sliding column 33 to drive multiple push plates 15 and multiple rubber baffles 14 to move away from each other, the grinding table 12 continues to rise until the rubber baffle 14 is tightly against the inner wall of the steel ring 4, which can center and clamp steel rings 4 of different sizes to ensure the accuracy of the grinding position.

[0039] When the multiple rubber stoppers 14 are pressed against the inner wall of the steel ring 4, the guide rod 5 rotates, and the guide rod 5 rotates to drive the limit block 6 to rotate through the insertion rod 7. The limit block 6 rotates to drive the gear ring 1 26 to rotate through the turntable 25. The gear ring 1 26 rotates to drive the multiple gears 1 28 to rotate. The multiple gears 1 28 rotate to drive the multiple extrusion plates 32 to move upward. The extrusion plates 32 move upward to squeeze the disc spring 18. At this time, each disc spring 18 is subjected to an upward extrusion force. When the size of the steel ring 4 is larger (smaller), the multiple rubber stoppers 14 move upward. The distance of movement is also larger (smaller), and the number of turns and distance that the guide rod 5 rotates in the rotating groove 21 is more (fewer), so that the number of turns driven by the limit block 6 to rotate the damping bearing 34 is less (more), and the gear ring 1 26 also decreases (increases) as the number of turns of the damping bearing 34 decreases (increases), so that the distance that the threaded rod 2 35 drives the extrusion plate 32 to move upward is smaller (larger). At this time, the extrusion force on the disc spring 18 is smaller (larger). When the extrusion force on the disc spring 18 is smaller, the elastic force is also larger, providing a gentle and Stable contact pressure can avoid inner diameter size deviation or surface damage caused by rigid impact during vibration, and is especially suitable for the grinding of large-sized steel rings 4; when the disc spring 18 is subjected to a large extrusion pressure, the elastic force at this time is also small, and it absorbs the vibration impact through its own deformation, while maintaining a constant grinding contact force, ensuring that the small-sized steel ring can effectively remove impurities during vibration grinding, and avoid overload of the steel ring 4 or wear of the grinding head caused by rigid collision (the "rigid response" characteristic when the disc spring 18 is subjected to a small extrusion pressure can make the grinding head vibrate at high frequency and small amplitude, accurately fitting the curvature change of the small-sized steel ring 4, and is especially suitable for grinding fine areas such as the edge of the inner hole and chamfers, reducing the risk of edge cracking; the "flexible buffering" characteristic when the disc spring 18 is subjected to a large extrusion pressure allows the grinding head to vibrate at low frequency and large amplitude, adapting to large-area rough treatment of the inner surface of the large-sized steel ring 4 (such as removing cast oxide scale), and the vibration energy is evenly transmitted through the deformation of the disc spring 18 to avoid local stress concentration). At this time, the pressure change value tested by the pressure sensor is also small (larger).

[0040] The use of the grinding head on the grinding mechanism 9 is controlled according to the pressure value tested by the pressure sensor, and a PLC controller (existing technology) is installed between the grinding mechanism 9 and the pressure sensor. When the pressure measured by the pressure sensor is large, the size indicates that the size of the steel ring 4 is small, and the larger grinding head is switched to grind the steel ring 4; when the pressure measured by the pressure sensor is small, the size indicates that the size of the steel ring 4 is large, and the smaller grinding head is switched to grind the steel ring 4.

[0041] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are common means well known to those skilled in the art.

[0042] The specific operation steps of the present invention are as follows:

[0043] S1, place the steel ring 4 to be polished on the fixed plate 11, turn on the electric telescopic rod, and drive the steel ring 4 to drop to the sliding mechanism 10 through the lifting plate. At this time, the sliding mechanism 10 is driven to move the steel ring 4 to the top of the polishing table 12. Then, the cylinder 3 is driven to extend its driving end to drive the polishing table 12 upward through the fixed plate 11, at this time, the steel ring 4 on the sliding mechanism 10 is lifted;

[0044] S2, the grinding table 12 continues to rise, at this time the limit block 6 will be engaged in the limit groove 20, and then the guide rod 5 enters the rotating groove 21, driving the swivel 22 to rotate, the rotation of the swivel 22 drives multiple gears 29 to rotate through the gear ring 2 30, the rotation of multiple gears 29 drives multiple rotating shafts 31 to rotate, the rotation of multiple rotating shafts 31 drives multiple bevel gears 24 to rotate, the rotation of multiple bevel gears 24 drives multiple threaded rods 19 to rotate through multiple bevel gears 1 23, the rotation of multiple threaded rods 19 drives multiple nuts to move away from each other, the multiple nuts move through the sliding column 33 to drive multiple push plates 15 and multiple rubber baffles 14 to move away from each other, until the rubber baffle 14 is tightly pressed against the inner wall of the steel ring 4, the steel ring 4 is centrally positioned and clamped;

[0045] S3, at this time, multiple push plates 15 and multiple rubber baffles 14 are difficult to move due to resistance, and the force between the guide rod 5 and the rotating groove 21 is greater than the resistance of the damping bearing 34. Under the action of the damping bearing 34, the insertion rod 7 rotates, and the damping bearing 34 rotates through the turntable 25 to drive the gear ring 26 to rotate. The rotation of the gear ring 26 drives the multiple gears 28 to rotate. The rotation of the multiple gears 28 drives the multiple extrusion plates 32 to move upward, and the extrusion plates 32 move upward to squeeze the disc springs 18. At this time, each disc spring 18 is subjected to an upward extrusion force and is adjusted to the appropriate stiffness required by the steel ring 4 of the corresponding size, so as to avoid overload of the steel ring 4 or wear of the grinding mechanism 9 due to rigid collision;

[0046] S4, at this time, the pressure sensor senses the pressure value change and controls the grinding mechanism 9 to adjust to the grinding mode suitable for the steel ring 4 according to the pressure change value.

[0047] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
