Abstract

An emery polishing wheel is disclosed. A polishing portion and a ring are disposed to the inside of two wheel disks respectively. The polishing portion is composed of a plurality of polishing pieces. The interior edge and the exterior edge of each polishing piece are designed with an equal-length so that the interior edge and the exterior edge of each polishing piece are in continuous curves. The ring can be leaned against by the point of a knife, and the ring is a single rotary structure that easily reaches the predetermined position of polishing the knife-edge to enable two sides of the knife-edge to be kept at the same height. Therefore, the invention can easily overcome the shaking and swing produced from the polishing of the point of the knife when the emery polishing wheel rotates at high speed. The invention not only improves stability, but also uniformly polishes the knife-edge.

If there is a chemical formula in this case, please reveal the chemical formula that best shows the characteristics of the invention. IX. INSTRUCTIONS OF THE INVENTION: TECHNICAL FIELD The present invention relates to the technical field of an abrasive cloth wheel structure, and more particularly to an abrasive cloth wheel structure that achieves topping and defines a tool tip position by a separately rotatable top ring. [Prior Art] 4 8 1279292 Please refer to Fig. 7 and Fig. 8, according to the present, the so-called abrasive cloth wheel is for the purpose of grinding the surface or shape of the workpiece, and the conventional abrasive cloth wheel structure is composed of a wheel 6 and a grinding portion 6 1 is composed of a combination of the polishing portion 6 1 . The wheel 6 is axially fixed with a plurality of polishing sheets 6 2 , each of which has an outer shape of one of the unequal lengths 6 2 1 And a rectangular movable piece composed of an inner edge 6 2 2 , and is aligned with each outer edge 621 and arranged in a mutually sequential arrangement, the wheel 6 is circumscribed by the periphery of each of the polishing pieces 6 2 Since the outer edges 6 2 1 of each of the polishing sheets 6 2 are in a pointed shape 63 3 , the unevenness of the processing surface may result in uneven grinding. Furthermore, as shown in Fig. 9 and Fig. 10, in terms of the technology of the conventional abrasive cloth wheel sharpening, the cutting edge 6 6 feed amount is visually matched to control the angle of the hand grip of the handle. The predetermined sharpening position is reached. Therefore, in order to achieve the predetermined sharpening position, if the cutting edge 66 is directly pressed down to the grinding portion 6 1 , the bilateral edge of the cutter 6 4 or the single edge cutting edge 6 5 is used as the grinding. The tip 6 6 does not have a positioning abutment device, so a bilateral blade edge 6 4 or a single blade edge 65 5 may occur, and the sand cloth wheel may be shaken and shaken when the knife blade is sharpened during high speed rotation. There is a danger of the tool bounce off. Therefore, it is necessary to study how to control the feed angle of the cutting edge with the angle of the hand holding the handle, and avoid the occurrence of the bilateral or unilateral blade height drop and how to overcome the abrasive cloth wheel in the high speed rotation. The wobble and swing generated during the sharpening of the knife makes the hand more stable when the handle is held, which becomes a main subject of the present invention. 5 8 1279292 Moreover, if the structure of each polishing piece 6 2 can be modified to match the abrasive cloth wheel, a more uniform processing surface can be obtained during the sharpening of the knife, so that the function of the abrasive cloth wheel sharpening knife is more perfect, which is really needed.
