[0022] Below, the present invention is further described with reference to the accompanying drawings and specific embodiments:

[0023] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0025] like Figure 1 、 Figure 2 as well as Figure 3 The electroplated diamond grinding wheel for honing grinding wheels shown in the figure includes a grinding wheel base 20 and a grinding wheel disc. The grinding wheel disc is provided with a grinding edge 11 and a connecting edge. The grinding edge 11 and the connecting edge are spaced apart from the outside to the inside in the radial direction of the grinding wheel disc, and the grinding wheel disc is mounted on the grinding wheel base 20. After the grinding wheel disc is mounted on the grinding wheel base 20, the connecting edge is fixedly connected to the outer peripheral wall of the grinding wheel base 20.

[0026] In addition, the grinding wheel is provided with a plurality of grinding surfaces 12 on both sides of its axial direction. The plurality of grinding surfaces 12 are gradually connected in an inclined state from close to the grinding edge 11 to far away from the grinding edge 11, and two adjacent grinding surfaces 12 are connected at an angle.

[0027] On the basis of the above structure, when using the electroplated diamond grinding wheel for honing grinding wheel of the present invention, during grinding, the grinding wheel base 20 of the grinding wheel structure can be connected to the driving part through the main shaft, and the driving part drives the grinding wheel base 20 to rotate. The grinding wheel disc on the grinding wheel base 20 can be extended into the slot of the gear to perform grinding with the grinding surfaces 12 on both sides of the grinding wheel disc.

[0028] Since multiple grinding surfaces 12 are provided at both ends of the grinding wheel disc's axial direction, the multiple grinding surfaces 12 can contact and grind with both sides of the groove. Since the multiple grinding surfaces 12 on the same side are connected in an inclined state, after the grinding edge 11 of the grinding wheel disc extends into the groove to be processed, the multiple grinding surfaces 12 on both sides are connected and can adapt to the inner wall structure of the groove for grinding. Through the multiple grinding surfaces connected at an angle to each other, grinding contacts are performed at different positions during the grinding extension process, so that the grinding effects at different positions are relatively consistent.

[0029] In addition, since the two grinding surfaces 12 are connected at an angle, the grinding surface 12 close to the grinding edge 11 is ground on the inner layer, and multiple grinding surfaces 12 are gradually tilted and connected toward the outer layer, which can gradually guide the grinding chips outward and prevent the accumulation of grinding chips from affecting the grinding accuracy.

[0030] Furthermore, a plurality of spacing grooves 13 can be provided on the grinding wheel disc, and the plurality of spacing grooves 13 are spaced apart in the circumferential direction of the grinding wheel disc. During the grinding process of the grinding wheel disc, a large amount of heat will be generated. The continuous contact between the grinding wheel surface and the workpiece will easily lead to heat concentration. The grinding wheel disc is spaced apart in the circumferential direction by a plurality of spacing grooves 13. The circumferential discontinuity can increase the heat dissipation area, so that the heat can be dissipated more effectively, thereby reducing the adverse effects of overheating on the workpiece and the grinding wheel.

[0031] Furthermore, the chips generated during grinding need to be promptly discharged. Intermittent settings provide more channels for chip discharge, preventing them from accumulating in the grinding area and affecting machining quality and grinding wheel life. It should also be emphasized that the intermittent grinding wheel surface has a relatively small contact area with the workpiece, thereby reducing grinding forces, deformation, and surface damage to the workpiece.

[0032] Specifically, the spacing groove 13 passes through the grinding edge 11. When the grinding edge 11 is processing the groove to be processed, the grinding edge 11 is located in the innermost layer. The spacing groove 13 passes through the grinding edge 11, and can discharge the innermost layer of grinding chips in time.

[0033] Furthermore, a diamond abrasive layer is provided on the grinding surface 12. Diamond is used as an abrasive, so that the grinding wheel has high hardness and a sharp cutting edge. The diamond abrasive can efficiently remove workpiece material, achieve rapid grinding, and improve processing efficiency.

[0034] Of course, the abrasive material mentioned above can also be selected as an MD material layer, CBN material layer, BC material layer, GC material layer or other abrasive material layer in the prior art, and the specific selection can be made according to actual needs.

[0035] Furthermore, the diamond abrasive layer is electroplated onto the grinding surface 12. During the electroplating process, the abrasive is plated onto the surface of the metal workpiece as part of the coating, which allows for a uniform distribution of many micro-powder hard points within the coating. For example, by using composite plating for a wear-resistant layer, the metal ions in the plating solution complex with the abrasive to form ion clusters that are then plated onto the workpiece surface, significantly increasing the wear resistance of the coating.

[0036] Furthermore, the connecting edge is connected to the outer peripheral wall of the grinding wheel base 20 by a guide bevel 14. The guide bevel 14 can guide the grinding discharged in sequence by multiple grinding surfaces 12 to the grinding wheel base 20 to quickly discharge the grinding chips and prevent the grinding chips from accumulating at the connecting position between the grinding wheel base 20 and the connecting edge.

[0037] Furthermore, a clamping hole 21 is provided in the middle of the grinding wheel base 20, and a keyway 211 is provided on the sidewall of the clamping hole 21. The grinding wheel base 20 can be connected and matched with the external spindle structure through the clamping hole 21, which facilitates clamping and use. Of course, a connecting flat key can be provided on the spindle. After the spindle is clamped to the clamping hole 21 of the grinding wheel base 20, the connecting flat key is inserted into the keyway 211 of the clamping hole 21 to achieve a key connection. In this way, when the grinding wheel base 20 rotates, the key connection is used to limit the rotation, preventing the grinding wheel from rotating relative to the spindle during rotation, thereby making the grinding process more stable.

[0038] More specifically, the grinding wheel base 20 may be provided with a plurality of connection holes 22, spaced apart around the circumference of the mounting hole 21. When electroplating the abrasive layer on the grinding wheel disc, a shielding plate may be mounted on the grinding wheel base 20 to shield static electricity during the electroplating process. The plurality of connection holes 22 on the grinding wheel base 20 may be connected to the shielding plate via bolts or other connecting structures, facilitating assembly.

[0039] Furthermore, the grinding wheel base 20 itself has clamping bosses 23 protruding from both ends of its axial direction. Based on the structure with the clamping bosses 23, the above-mentioned clamping holes 21 pass through to the end faces of the clamping bosses 23. The clamping bosses 23 can be used for clamping with an external clamping structure, so that the clamping bosses 23 protrude from the grinding wheel base 20, making it more convenient to clamp and not easy to fall off after clamping, thereby providing clamping stability for the grinding wheel base 20.

[0040] Those skilled in the art can make various other corresponding changes and deformations based on the technical solutions and concepts described above, and all of these changes and deformations should fall within the scope of protection of the claims of the present utility model.
