[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model; that is, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The components of the embodiments of the present utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0032] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0033] The following is combined with Figure 1-2 This invention describes a high-precision grinding wheel dressing machine, comprising:

[0034] Support platform 1;

[0035] A drive device 2 is installed on the support platform 1. The drive device 2 includes a drive motor 21. A transmission shaft 22 is fixedly provided on the output end of the drive motor 21. A grinding wheel 5 is installed on the transmission shaft 22 and rotates synchronously with it. The rotation of the drive motor is used to drive the transmission shaft 22 to rotate. The grinding wheel 5 is installed on the transmission shaft 22, so that the drive motor 21 drives the transmission shaft 22 and the grinding wheel 5 to rotate synchronously. While the grinding wheel 5 is rotating, a grinding wheel dressing plate 34 is placed on one side of the grinding wheel 5 to rub against the grinding wheel 5. Since the hardness of the grinding wheel dressing plate 34 is greater than that of the grinding wheel 5, the grinding wheel 5 and the grinding wheel dressing plate 34 rub against each other, so that the peripheral surface of the grinding wheel 5 is rubbed until smooth and flat, realizing the reuse of the grinding wheel 5.

[0036] A moving device 3 is installed on the support platform 1 and located on one side of the grinding wheel 5. The moving device 3 includes a horizontal moving platform 31 and a vertical moving platform 32. The horizontal moving platform 31 and the vertical moving platform 32 are slidably connected to the support platform 1, and the sliding trajectories of the horizontal moving platform 31 and the vertical moving platform 32 are perpendicular. A grinding wheel dressing disc 34 is installed on the vertical moving platform 32, with one end of the grinding wheel dressing disc 34 facing the side cut surface of the grinding wheel 5. The horizontal moving platform 31 can slide horizontally on the support platform 1, while the vertical moving platform 32 can slide laterally on the horizontal moving platform 31. The grinding wheel dressing disc 34 is installed on the top of the vertical moving platform 32. The grinding wheel dressing disc 34 can move back and forth along the side cut surface of the grinding wheel 5 by the movement of the horizontal moving platform 31 and the vertical moving platform 32 at its bottom, thereby grinding the grinding wheel 5 back and forth and polishing the uneven grinding wheel 5 into a smooth circumferential surface.

[0037] Please refer to Figure 2As shown, the bottom of the horizontal moving platform 31 is provided with a first slide rail 312, which is fixedly connected to the support platform 1. The horizontal moving platform 31 is slidably connected to the first slide rail 312. A first threaded rod 311 is threadedly engaged on the first slide rail 312 to drive the horizontal moving platform 31 and the first slide rail 312 to slide relative to each other. One end of the first threaded rod 311 is rotatably connected to the horizontal moving platform 31. A threaded fitting (not shown) is provided on the side of the first slide rail 312 near the drive motor 21. The structural principle of the threaded fitting is the same as that of the threaded sleeve 325 area in this solution. The threaded fitting is fixedly connected to the first slide rail 312. The first threaded rod 311 and the threaded rod 311 are threaded together. The threaded connection of the mating parts is such that the other end is rotatably connected to the horizontal moving table 31, so that when the first threaded rod 311 is rotated, the horizontal moving table 31 can be driven to slide on the first slide rail 312. When the grinding operator grinds the grinding wheel 5, the friction between the grinding wheel 5 and the grinding wheel dressing plate 34 will cause the length of the grinding wheel dressing plate 34 to gradually decrease, resulting in it not being able to fit tightly against the grinding wheel 5 and affecting the grinding of the grinding wheel 5. In this solution, by controlling the rotation of the first threaded rod 311, the mutual proximity or distance between the grinding wheel dressing plate 34 and the grinding wheel 5 is controlled, thereby adjusting the distance between the grinding wheel 5 and the grinding wheel dressing plate 34, so that the grinding wheel dressing plate 34 fits tightly against the grinding wheel 5, thereby achieving precise grinding of the grinding wheel 5.

[0038] Please refer to Figure 2 As shown, the top of the horizontal moving table 31 is provided with a second slide rail, which is fixedly connected to the top of the horizontal moving table 31. The vertical moving table 32 is slidably connected to the second slide rail. The top of the vertical moving table 32 is fixedly provided with a support plate 33. The sliding between the vertical moving table 32 and the horizontal moving table 31 is used to adjust the lateral position of the grinding wheel dressing disc 34, so that the grinding wheel dressing disc 34 moves back and forth along the height direction of the grinding wheel 5, thereby grinding the grinding wheel 5.

[0039] Please refer to Figure 2 As shown, the support plate 33 is provided with:

[0040] The slide groove 321 is distributed along the length of the vertical moving table 32 and is used to limit the position of the grinding wheel dressing disc 34;

[0041] The abutment block 322 is slidably connected within the slide groove 321, and the abutment block 322 is limited to sliding within the slide groove 321;

[0042] A stop block 323 is fixedly connected to one end of the vertical moving table 32. A clamping space is formed between the abutment block 322 and the stop block 323. The grinding wheel dressing disc 34 is clamped in the clamping space. By sliding the abutment block 322 in the slide groove 321, the grinding wheel dressing disc 34 is clamped between the abutment block 322 and the stop block 323. The sliding adjustment of the abutment block 322 can realize the clamping of grinding wheel dressing discs 34 of different sizes.

[0043] Please refer to Figures 1-2 As shown, the support plate 33 is further provided with:

[0044] The second threaded rod 324 has one end rotatably connected to the abutment block 322;

[0045] A threaded sleeve 325 is fixedly connected to the top of the support plate 33, and the second threaded rod 324 is threadedly engaged with the threaded sleeve 325.

[0046] The handle 326 is fixedly connected to the end of the second threaded rod 324 away from the abutment 322. One end of the second threaded rod 324 is rotatably connected to the abutment 322. By rotating the second threaded rod 324, the abutment 322 and the stop block 323 are brought closer or further apart, thereby clamping the grinding wheel dressing disc 34.

[0047] Please refer to Figures 1-2 As shown, the end of the drive shaft 22 away from the drive motor 21 has a thread. The drive shaft 22 is provided with a locking bolt 23, which is threadedly engaged with the drive shaft 22. The locking bolt 23 is used to lock the grinding wheel 5 on the drive shaft 22. The grinding wheel 5 is limited and sleeved on the drive shaft 22. At the same time, the thread formed on the drive shaft 22 and the locking bolt 23 are threadedly engaged to limit the position of the grinding wheel 5 on the drive shaft 22, prevent the grinding wheel 5 from sliding back and forth along the length direction of the drive shaft, and make the grinding wheel 5 rotate synchronously with the drive shaft 22.

[0048] Please refer to Figure 1 As shown, several grinding wheels 5 can be installed on the drive shaft 22, and multiple grinding wheels 5 can be used for synchronous grinding at the same time.

[0049] Please refer to Figure 1 As shown, a fluid basin 4 is provided on the support platform 1. The fluid basin 4 is located directly below the grinding wheel 5. The fluid basin 4 contains fluid, and the fluid in the fluid basin 4 can prevent grinding dust from being stirred up everywhere when grinding the grinding wheel 5.

[0050] The working principle of this utility model:

[0051] Several grinding wheels 5 are fitted onto the drive shaft 22, and locking bolts 23 are locked onto the drive shaft 22, so that the locking bolts 23 lock the lateral movement of the grinding wheels 5, and the grinding wheels 5 rotate synchronously with the drive shaft 22.

[0052] The grinding wheel dressing disc 34 is placed between the abutment block 322 and the stop block 323, and the handle 326 is rotated so that the handle 326 and the second threaded rod 324 rotate synchronously on the threaded sleeve 325 and the abutment block 322. The threaded engagement between the second threaded rod 324 and the threaded sleeve 325 is used to change the distance between the abutment block 322 and the stop block 323, thereby clamping the grinding wheel dressing disc 34 between the stop block 323 and the abutment block 322.

[0053] Start the drive motor 21 to drive the grinding wheel 5 to rotate;

[0054] The right hand holds the vertical moving table 32, which slides along the second slide rail at its bottom, causing the grinding wheel dressing disc 34 to move back and forth along the height direction of the grinding wheel 5. During the vertical sliding of the vertical moving table 32, the grinding wheel dressing disc 34 continuously contacts and rubs against the surface of the grinding wheel 5, thereby achieving the flatness grinding of the grinding wheel 5.

[0055] During the friction between the grinding wheel 5 and the grinding wheel dressing disc 34, the wear of the grinding wheel dressing disc 34 causes it to be unable to tightly adhere to the circumference of the grinding wheel 5. By controlling the rotation of the first threaded rod 311 from left to right, the first threaded rod 311 drives the horizontal moving table 31 to slide horizontally along the support table 1, thereby controlling the distance between the grinding wheel dressing disc 34 and the grinding wheel 5. This achieves the supply of the grinding wheel dressing disc 34 to the grinding wheel 5, ensuring that the grinding wheel 5 and the grinding wheel dressing disc 34 are always in close contact during grinding, improving the grinding effect on the grinding wheel 5 and shortening the grinding time.

[0056] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0057] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
