[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 5 The illustrated embodiment of a diamond grinding tool for easy assembly and disassembly includes a tool bar 10, a tool sleeve 20, and a tool head 30. The tool bar 10 has a first end 11 and a second end 12. The tool sleeve 20 is mounted on the tool bar 10 via the first end 11. A diamond abrasive layer is provided on the surface of the tool sleeve 20. The tool sleeve 20 is provided with a chip groove 21 extending along the axial direction of the tool bar 10. The chip groove 21 guides the removal of grinding chips. The tool head 30 is detachably connected to the first end 11, so that the tool sleeve 20 is locked to the first end 11.

[0026] On the basis of the above structure, the diamond grinding tool of the utility model which is easy to disassemble and assemble is used. When in use, when grinding a drill bit, the second end 12 of the arbor 10 of the diamond grinding tool is clamped on the processing spindle of the grinder, and then the processing spindle is driven to rotate by the driving member of the grinder. The processing spindle can drive the arbor 10 to rotate, and then drive the tool sleeve 20 on the first end 11 of the arbor 10 to rotate. The tool sleeve 20 can be inserted into the hole to be processed, and the diamond abrasive layer on the surface of the tool sleeve 20 is ground with the inner wall of the processed hole, which has good strength and high grinding accuracy.

[0027] In addition, since a chip groove 21 is provided on the surface of the tool sleeve 20 and the chip groove 21 extends along the tool sleeve 20, the chip groove 21 can guide the grinding chips generated by the rotating tool sleeve 20 during grinding to be discharged axially, thereby preventing the grinding chips from accumulating on the surface of the tool sleeve 20 and causing grinding jams.

[0028] It should also be noted that the above-mentioned knife sleeve 20 is locked at the first end 11 through the knife head 30. Therefore, after the knife sleeve 20 is worn out, the knife sleeve 20 can be replaced by removing the knife head 30 from the first end 11.

[0029] Furthermore, the outer peripheral wall of the first end 11 can also be a conical surface, and the outer diameter of the conical surface gradually increases from away from the second end 12 to close to the second end 12. In this way, after the cutter head 30 penetrates from the first end 11, during the penetration process, the outer diameter of the first end 11 gradually increases, and thus the fit between the cutter head 30 and the inner wall of the tool sleeve 20 can be gradually tightened to achieve a firm assembly. Thereafter, the cutter head 30 is detachably connected to the end face of the first end 11, and after being assembled to the first end 11, the cutter head 30 can abut against the end face of the tool sleeve 20 away from the second end 12 to achieve axial limitation of the tool sleeve 20, so that the assembly structure of the tool sleeve 20 is more stable.

[0030] Furthermore, the cutter head 30 in this embodiment includes a resting section 31 and a tapered guide section 32. After the cutter head 30 is locked to the first end 11, the resting section 31 of the cutter head 30 connects to the end surface of the first end 11 and rests against the end surface of the tool sleeve 20. The flat abutment between the end surfaces achieves position limiting, making the position limiting structure more stable. The tapered guide section 32 can form a tapered head to guide the entire mold into the processing hole.

[0031] Furthermore, a threaded hole 111 can be provided at the first end 11, and a threaded column 331 can be provided at the abutting section 31. When the cutter head 30 is assembled on the first end 11 of the tool rod 10, the threaded column 331 of the cutter head 30 can be threadedly connected to the threaded hole 111 so that the abutting section 31 abuts against the end face of the tool sleeve 20, which facilitates disassembly and assembly.

[0032] Furthermore, the outer peripheral wall of the tapered guide section 32 is provided with a flat surface 332. When the cutter head 30 and the first end 11 are threadedly connected, the flat surface 332 of the tapered guide section 32 of the cutter head 30 can be used for disassembly and assembly by external tools such as wrenches.

[0033] Of course, a flat key may be provided at the end of the cutter head 30 and a flat key slot may be provided at the first end 11 of the cutter bar 10 to achieve a fitting connection by using the flat key and key slot structure.

[0034] Furthermore, the chip removal groove 21 extends spirally in the axial direction of the tool rod 10, so that when removing chips, the grinding chips can move along the spiral direction and avoid the grinding pin position for chip removal.

[0035] Furthermore, the outer surface of the first end 11 is provided with a diamond abrasive layer. Specifically, the above-mentioned tool rod 10 is made of grinding tool steel, and can be sand-plated after the tool rod 10 is manufactured to improve the strength of the tool rod 10. At the same time, the first end 11 of the tool rod 10 can also be provided with a diamond grinding wheel layer. The tool sleeve 20 is installed at the first end 11. The diamond grinding wheel layer on the tool sleeve 20 is used as the main grinding base, and the diamond abrasive layer on the first end 11 of the tool rod 10 can also be used as an auxiliary grinding base, thereby improving the grinding efficiency.

[0036] Furthermore, the second end 12 is provided with a connector 121, and the connector 121 can be a threaded connector 121 or a plug-in connector or a spline connector 121 in the prior art, so that the tool rod 10 can be detachably connected to the machining spindle on the external grinding machine through the connector 121 at the second end 12.

[0037] 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.
