[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Example 1

[0023] See also Figures 1-4 A device for correcting the surface flatness of a grinding wheel comprises a base 100. A linear motor 200 is mounted on the top of the base 100. The bottom of the linear motor 200 is connected to a servo motor 300 and a telescopic limit plate 700. The bottom of the linear motor 200 is connected to a correction wheel 400. When the linear motor 200 is started, the servo motor 300 and the telescopic limit plate 700 connected thereto are driven to move downward. The telescopic limit plate 700 performs a preliminary limit on the grinding wheel located therein. Subsequently, when the servo motor 300 is started, the correction wheel 400 connected thereto is driven to rotate, thereby performing a corresponding correction operation on the grinding wheel.

[0024] A limit assembly 500 is mounted on the top of the base 100. This assembly includes a hydraulic device 501, which is composed of a hydraulic housing and hydraulic hoses. A turntable 502 is connected to the bottom of the servo motor 300. When the grinding wheel is being corrected, the servo motor 300 synchronously drives the turntable 502, to which it is connected, to rotate clockwise. A squeeze rod 503 is fixedly connected to the outer side of the turntable 502. Clockwise rotation of the turntable 502 causes the squeeze rod 503 to rotate synchronously with it. A force-bearing rod 504 is slidably connected to the side of the hydraulic device 501. A spring 505 is fixedly connected to the side of the force-bearing rod 504. The end of the spring 505, located away from the force-bearing rod 504, is located inside the hydraulic device 501 and is fixedly connected to the inner wall of the hydraulic device 501. A push rod 1 506 is slidably connected to the side of the hydraulic device 501. A telescopic support plate 507 is fixedly connected to the side of the push rod 1 506. When the extrusion rod 503 rotates, it can squeeze the force-bearing rod 504 and drive it to move. The force-bearing rod 504 then squeezes the spring 505 fixedly connected to it and moves. In conjunction with the hydraulic device 501 slidably connected to the force-bearing rod 504, the pressure in the hydraulic device 501 increases, driving the push rod 1 506 slidably connected to the hydraulic device 501 to move, so that the push rod 1 506 drives the telescopic support plate 507 to move. The four telescopic support plates 507 further restrict the grinding wheel, thereby improving the flattening effect of the grinding wheel.

[0025] When in use, the linear motor 200 is started, driving the servo motor 300 and the telescopic limit plate 700 connected thereto to move downward, and the telescopic limit plate 700 performs a preliminary limit on the grinding wheel located therein, and then the servo motor 300 is started, which can drive the correction wheel 400 connected thereto to rotate to perform a corresponding correction operation on the grinding wheel; at this time, the servo motor 300 synchronously drives the turntable 502 connected thereto to rotate clockwise, so that the turntable 502 drives the extrusion rod 503 fixedly connected thereto to rotate synchronously, and the extrusion rod 503 immediately squeezes the force-bearing rod 504 and drives it to move, and the force-bearing rod 504 immediately squeezes the spring 505 fixedly connected thereto to move, and cooperates with the hydraulic device 501 slidably connected to the force-bearing rod 504, so that the pressure in the hydraulic device 501 increases, driving the push rod 1 506 slidably connected to the hydraulic device 501 to move, so that the push rod 1 506 drives the telescopic support plate 507 to move, and the four telescopic support plates 507 further limit the grinding wheel. Example 2

[0026] See also Figures 1-4 Based on the first embodiment, a support assembly 600 is provided on the side of the base 100. The support assembly 600 includes a hydraulic chamber 601. One end of the hydraulic chamber 601 is slidably connected to a transmission rod 602. The transmission rod 602 is located to the side of the fixed portion of the telescopic limit plate 700 and is fixedly connected to the fixed portion. When the telescopic limit plate 700 moves downward, it drives the transmission rod 602, which is fixedly connected to the telescopic limit plate 700, to move downward. This, in conjunction with the hydraulic chamber 601, which is slidably connected to the transmission rod 602, increases the pressure within the hydraulic chamber 601. The other end of the hydraulic chamber 601 is slidably connected to a second push rod 603. A rotating shaft 604 is rotatably connected to the side of the base 100. A stabilizing plate 605 is fixedly connected to the outer side of the rotating shaft 604. The stabilizing plate 605 is located at the bottom of the second push rod 603 and is fixedly connected to the second push rod 603. When the pressure in the hydraulic chamber 601 increases, the push rod 2 603 that is slidingly connected to the hydraulic chamber 601 moves, so that the push rod 2 603 drives the stabilizing plate 605 fixedly connected to it to rotate. The stabilizing plates 605 on both sides can be rotated to the bottom position to provide auxiliary support, thereby further improving the stability of the device during use.

[0027] During use, based on Example 1, when the telescopic limit plate 700 moves downward, it can drive the transmission rod 602 fixedly connected to the telescopic limit plate 700 to move downward, and cooperate with the hydraulic warehouse 601 slidingly connected to the transmission rod 602, so that the pressure in the hydraulic warehouse 601 increases, driving the push rod 2 603 slidingly connected to the hydraulic warehouse 601 to move, so that the push rod 2 603 drives the stabilizing plate 605 fixedly connected to it to rotate, and the stabilizing plates 605 on both sides can be rotated to the bottom position for auxiliary support.

[0028] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
