Abstract
Description
Technical Field
[0001] The utility model relates to the field of high-strength grinding tool and grinding wheel, in particular to a self-sharpening abrasive tool. Background Art
[0002] After long-term use, the abrasive part of the grinding tool, especially the surface in direct contact with the workpiece, will turn black, causing abrasive blockage. Continuing to use it will cause large grinding resistance, reduced cutting efficiency, and increased spindle load of the grinder. In severe cases, it will also cause damage to the machine tool spindle and the grinding wheel to be scrapped. Therefore, it is necessary to sharpen the grinding tool in time. The general treatment method is to use oilstone to sharpen it, or grind pig iron to achieve the effect of sharpening the abrasive surface. However, this sharpening method requires opening the machine tool protective cover for operation on closed automated equipment, and the grinding tool needs to be disassembled when necessary, which affects the efficiency of cutting the workpiece.

[0019] The following will describe exemplary embodiments of the present application with reference to the accompanying drawings. However, it should be understood that the present application can be presented in a variety of different ways and is not limited to the embodiments described below. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide more additional embodiments. In all drawings, the same reference numerals represent the same or functionally identical elements.
[0020] See also Figure 1 The abrasive tool is basically composed of a base 10 and an abrasive part 20 bonded to the outer peripheral surface of the base. In order to promote the chip removal efficiency of the abrasive part 20 during the cutting process, a storage structure 30 connected to the outer peripheral surface 15 is provided on the mounting surface 14. The storage structure 30 stores a colloidal abrasive particle mixture that is used for auxiliary grinding of the abrasive part 20 and is thrown out as the abrasive tool rotates.
[0021] Combination Figure 2 As shown, the abrasive portion 20 is evenly arranged on the outer periphery of the base 10, and its outer side edge 22 forms an angle of less than 90° with the cutting surface 13 for cutting the edge corner 21 of the workpiece. In order to ensure that the abrasive portion 20 is stably and evenly worn during the cutting process of the edge corner 21, its inner side edge 23 is designed to be parallel to the outer side edge 22. Furthermore, the outer edge 11 of the base 10 is also set to an inclined angle that matches the inner side edge 23, so that the base 10 is trapezoidal or wedge-shaped from a cross-sectional perspective.
[0022] The storage structure 30 passes through the base 10 and the abrasive part 20. Specifically, a storage channel 33 is provided inside the abrasive part 20 and the base 10, and an injection channel 34 is provided inside the base 10. The injection channel 34 injects the mixture through the injection port 31 located on the mounting surface 14. The mixture can be added by using a syringe when the machine tool is stopped without disassembling the abrasive tool. The injection channel 34 is connected to the storage channel 33 and the angle 34a of its axis is an obtuse angle so that the colloidal abrasive particle mixture can smoothly enter the storage channel 33 with low resistance from one side of the injection channel 34, and finally be discharged through the discharge port 32 located on the outer edge 22.
[0023] In one embodiment, the material storage channel 33 is designed so that the cutting surface 13 and the mounting surface 14 are parallel, so that the mixture can be gradually thrown out more easily as the abrasive tool rotates.
[0024] In one embodiment, a mounting hole 12 for fixing the grinding tool on a machine tool is coaxially opened on the axis of the base 10 .
[0025] In one embodiment, the colloidal abrasive particle mixture is a green silicon carbide particle suspension colloid. By controlling the concentration of the green silicon carbide particles, the green silicon carbide particles are in a gel state and can be stored in the storage structure 30. When the abrasive tool is not rotating, it is not easy to leak out, and when the abrasive tool rotates at a high speed, it can slowly overflow. When the abrasive tool contacts the workpiece, the green silicon carbide abrasive particles are introduced to remove the deposits and clogging substances on the surface of the abrasive part, so as to achieve a sharpening effect.
