Description

Technical Field

[0001] This utility model relates to the field of grinding wheel testing technology, and more specifically, to a testing device for grinding wheel processing. Background Technology

[0002] Grinding wheels are common grinding tools widely used in metal processing, woodworking, stone cutting, and other fields. After the grinding wheel is manufactured and shaped, a testing device is needed to check the flatness of the grinding wheel surface.

[0003] Patent document CN222048995U discloses a grinding wheel flatness testing device. This device includes a flatness testing platform, with a drive motor fixedly connected to the top of the platform. A rotating shaft is fixedly connected to the output end of the drive motor, and a grinding wheel is slidably fitted onto the surface of the rotating shaft. A threaded groove is formed at the end of the rotating shaft away from the drive motor. A fixing device is provided on the surface of the rotating shaft. This grinding wheel flatness testing device uses three fixing rods to drive three wear-resistant balls to gradually press against the surface of the grinding wheel, thereby fixing the grinding wheel onto the surface of the rotating shaft. The self-locking action of the threaded sleeve further secures the grinding wheel. This facilitates the installation of grinding wheels of different thicknesses at the output end of the drive motor, improving the convenience of testing grinding wheels of different specifications and accelerating the efficiency of grinding wheel testing.

[0004] During use, this device is fixed to the grinding wheel through the center hole. However, it can only fix the center hole of a grinding wheel of a single size. When testing grinding wheels of different specifications, the grinding wheel may shift or loosen after installation. This shift not only affects the testing accuracy and causes errors in the measurement results, but may also pose a safety hazard when the grinding wheel is not securely fixed at high speed. Secondly, the device can only test one side of the grinding wheel. When testing the other side of the grinding wheel, it needs to be disassembled, flipped, and then fixed again, which is complicated and reduces the efficiency of grinding wheel testing.

[0030] Please see Figures 1-5 A testing device for grinding wheel processing includes a testing table 1, a movable component on the testing table 1, a flatness tester 2 movably connected to the testing table 1 via the movable component, a rotating component on the testing table 1, a rotating shaft 3 movably connected to the testing table 1 via the rotating component, a fixed chamber 4 inside the rotating shaft 3, a bidirectional lead screw 5 rotatably mounted inside the fixed chamber 4, a handle 6 fixedly mounted at one end of the bidirectional lead screw 5 passing through the rotating shaft 3, two drive seats 7 threadedly connected to the bidirectional lead screw 5, four fixed blocks 8 movably mounted on the outside of the rotating shaft 3, each fixed block 8 having a V-shaped fixing groove 9, and a drive rod 10 hingedly connected to each fixed block 8 and the two drive seats 7 respectively.

[0031] In this embodiment, when fixing the grinding wheel that needs to be tested for flatness, the grinding wheel is placed on the outside of the rotating shaft 3 and moved to the outside of the four fixing blocks 8. The handle 6 is rotated, which drives the bidirectional lead screw 5 to rotate. Since the bidirectional lead screw 5 has two threaded areas with opposite directions, the two drive seats 7 move in adjacent directions. The drive seats 7 drive the drive rod 10 to rotate, which in turn drives the fixing blocks 8 to move away from the rotating shaft 3. With the cooperation of the four fixing blocks 8, the grinding wheel is fixed according to the size of the center hole of different grinding wheels. Since the fixing groove 9 is V-shaped, it can fix grinding wheels of different thicknesses.

[0032] Please see Figures 1-5 As one embodiment for inspecting grinding wheels: the rotating assembly includes a support base 11, which is rotatably connected to the rotating shaft 3 via bearings. A turntable 12 is fixedly mounted on the lower end of the support base 11, and the turntable 12 is rotatably connected to the inspection table 1. A drive shaft 13 is fixedly mounted on the lower end of the turntable 12, and a gear ring 14 is fixedly mounted on the lower end of the drive shaft 13 passing through the inspection table 1. A first motor 15 is fixedly mounted on the lower end of the inspection table 1, and a rotating gear 16 is fixedly mounted on the drive end of the first motor 15. The rotating gear 16 meshes with the gear ring 14. A second motor 17 is fixedly mounted on the turntable 12, and a rotating rod 18 is fixedly mounted on the drive end of the second motor 17. The rotating rod 18 is rotatably connected to a limited... Position plate 19, limit plate 19 is fixedly connected to support base 11, one end of rotating rod 18 passes through limit plate 19 and is fixedly provided with driving bevel gear 20, one end of rotating shaft 3 passes through support base 11 and is fixedly provided with driven bevel gear 21, driven bevel gear 21 is meshed with driving bevel gear 20, moving assembly includes moving shell 22, moving shell 22 is fixedly connected to detection table 1, screw 23 is rotatably provided in moving shell 22, third motor 24 is fixedly provided on one side of moving shell 22, the driving end of third motor 24 extends into moving shell 22 and is fixedly connected to screw 23, moving base 25 is threadedly connected on screw 23, flatness detector 2 is fixedly provided on moving base 25.

[0033] More specifically, when it is necessary to test the flatness of the fixed grinding wheel, the third motor 24 is started. The third motor 24 drives the screw 23 to rotate. Since the screw 23 is threadedly connected to the moving seat 25, the moving seat 25 moves along the inside of the moving housing 22. The moving seat 25 drives the flatness tester 2 to move. Since the flatness tester 2 is equipped with a display and a probe, the probe moves with the flatness tester 2, so that one end of the probe contacts the surface of the grinding wheel. At the same time, the second motor 17 is started. The second motor 17 drives the rotating rod 18 to rotate. The rotating rod 18 drives the driving bevel gear 20 to rotate. The driving bevel gear 20 drives the driven bevel gear 21 to rotate. The driven bevel gear 21 drives the rotating shaft 3 to rotate around the support base 11. The rotating shaft 3 drives the fixed grinding wheel to rotate, activating the flatness tester 2 to test the flatness of the grinding wheel. After testing one side of the grinding wheel, the third motor 24 is activated, causing it to reverse and move the flatness tester 2 back to its original position. Simultaneously, the first motor 15 is activated, driving the rotating gear 16 to rotate. The rotating gear 16 drives the rotating rod 18 and the turntable 12 to rotate via the gear ring 14. The turntable 12 drives the support base 11, the rotating shaft 3, and the fixed grinding wheel to rotate, thus rotating the other side of the grinding wheel to face the flatness tester 2. The third motor 24 is then activated, causing the flatness tester 2 to move and bring the probe into contact with the grinding wheel, thereby testing the flatness of the other side of the grinding wheel. Since the flatness tester 2 has been disclosed in patent publication number CN222048995U, entitled "A Grinding Wheel Flatness Testing Device," and its display screen, probe, and working principle are all prior art, they will not be described in detail here.

[0034] In summary, when using or operating the entire equipment: when fixing the grinding wheel that needs to be tested for flatness, place the grinding wheel on the outside of the rotating shaft 3 and move the grinding wheel to the outside of the four fixing blocks 8. Rotate the handle 6, which drives the double-acting screw 5 to rotate. Since the double-acting screw 5 has two threaded areas in opposite directions, the two drive seats 7 move in adjacent directions. The drive seats 7 drive the drive rod 10 to rotate, which in turn drives the fixing blocks 8 to move away from the rotating shaft 3. With the cooperation of the four fixing blocks 8, the grinding wheel is fixed according to the size of the center hole of different grinding wheels. Since the fixing groove 9 is V-shaped, it can fix grinding wheels of different thicknesses.

[0035] When the flatness of the fixed grinding wheel needs to be checked, the third motor 24 is started. The third motor 24 drives the screw 23 to rotate. Since the screw 23 is threadedly connected to the movable seat 25, the movable seat 25 moves along the inside of the movable housing 22. The movable seat 25 drives the flatness tester 2 to move. Since the flatness tester 2 is equipped with a display and a probe, the probe moves with the flatness tester 2, so that one end of the probe contacts the surface of the grinding wheel. At the same time, the second motor 17 is started. The second motor 17 drives the rotating rod 18 to rotate. The rotating rod 18 drives the driving bevel gear 20 to rotate. The driving bevel gear 20 drives the driven bevel gear 21 to rotate. The driven bevel gear 21 drives the rotating shaft 3 to rotate around the connection point with the support seat 11. The rotating shaft 3 drives the fixed grinding wheel to rotate, activating the flatness testing instrument 2 to test the flatness of the grinding wheel. After testing one side of the grinding wheel, the third motor 24 is activated, causing it to reverse and move the flatness testing instrument 2 back to its original position. Simultaneously, the first motor 15 is activated, driving the rotating gear 16 to rotate. The rotating gear 16, through the gear ring 14, drives the rotating rod 18 and the turntable 12 to rotate. The turntable 12 drives the support base 11, the rotating shaft 3, and the fixed grinding wheel to rotate, thus rotating the other side of the grinding wheel to face the flatness testing instrument 2. The third motor 24 is then activated, causing the flatness testing instrument 2 to move and bring the probe into contact with the grinding wheel, thereby testing the flatness of the other side of the grinding wheel. Since the flatness testing instrument 2 has been disclosed in patent publication number CN222048995U, entitled "A Grinding Wheel Flatness Testing Device," and its display screen, probe, and working principle are all prior art, they will not be described in detail here.

[0036] In all the solutions mentioned above, those involving the operation of electrical components are all connected to an external power source. In addition, unless otherwise specified, they are all controlled by a controller. Since the devices matched with the controllers are common devices, their control principles and circuit connections are existing, well-known and mature technologies. Therefore, their electrical connection relationships and specific circuit structures will not be described in detail here.

[0037] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred.
