Technical Field
[0001] This utility model relates to a grinding head, specifically a grinding head. Background Technology
[0002] Grinding heads are used in metal processing to polish surfaces and make them smoother. Current grinding heads use dotted or striped grinding edges, which are prone to breakage and result in poor polishing effects. Utility Model Content

[0012] Figure 1 This is a schematic diagram of the grinding head provided in an embodiment of the present invention. Detailed Implementation
[0013] The present invention will be further described in detail below with reference to the accompanying drawings.
[0014] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
[0015] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0016] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0017] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0018] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
[0019] Example:
[0020] like Figure 1 As shown, a grinding head includes a handle 1 and a blade head 2. The blade head 2 is provided with multiple rows of first grinding edges 3 and multiple rows of second grinding edges 4, which are arranged alternately. The first grinding edges 3 include a blade body 32, a front tip 31, and a rear tip 33, with the front tip 31 and the rear tip 33 respectively located at both ends of the blade body 32. The second grinding edges 4 include a forward grinding edge 41 and a reverse grinding edge 42. One end of the forward grinding edge 41 is connected to the reverse grinding edge 42, and the other end is alternately arranged with the adjacent rear tip 33 on the same side. The other end of the reverse grinding edge 42 is also alternately arranged with the adjacent rear tip 33 on the same side. This utility model uses two grinding edges arranged alternately to enhance the grinding effect and increase the strength of the grinding head.
[0021] The blade body 32 is arc-shaped. The angle between the front tip 31 and the blade body 32 is a first acute angle, and the angle between the rear tip 33 and the blade body 32 is a second acute angle. The first and second acute angles are the same, and the front tip 31 and the rear tip 33 are in opposite directions. The connection between the blade body 32, the front tip 31, and the rear tip 33 forms a centrally symmetrical structure, increasing strength and making grinding smoother and more stable. The acute angle structure also improves the strength of the grinding blade itself.
[0022] The width of the front tip 31 gradually narrows from its connection with the cutting edge body 32 to its free end; the width of the rear tip 33 also gradually narrows from its connection with the cutting edge body 32 to its free end. This gradual narrowing reduces the cutting force between the grinding head and the workpiece.
[0023] The obtuse angle connection between the forward grinding edge 41 and the reverse grinding edge 42 widens the entire width of the second grinding edge, resulting in better strength.
[0024] The width of the forward grinding edge 41 gradually narrows from the connection point with the reverse grinding edge 42 to its free end, and the width of the reverse grinding edge 42 gradually narrows from the connection point with the forward grinding edge 41 to its free end. This gradual narrowing reduces the cutting force between the grinding head and the workpiece.
[0025] The adjacent first grinding blades 3 are symmetrical to each other, and the adjacent second grinding blades 4 are symmetrical to each other, further enhancing the strength.
[0026] The width L1 of the first grinding edge 3 is 1.5 to 1.8 times that of the width of the second grinding edge 4, resulting in better strength.
[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
