Description

Technical Field

[0001] This utility model relates to the field of polishing technology, and in particular to an abrasive grinding wheel that prevents edge chipping. Background Technology

[0002] Abrasive grinding wheels, also known as bonded abrasives, are abrasives in which ordinary abrasives are bonded together with a binder into a certain shape, mostly round, with a through hole in the center, and have a certain strength.

[0003] Comparing with the published patent number CN218697764U, a composite grinding wheel for preventing chipping in ceramic processing is disclosed, comprising a substrate and an abrasive layer. The abrasive layer is disposed on the side end of the substrate and has an annular structure. The abrasive layer is a composite abrasive layer, which consists of diamond teeth embedded in resin and bonded with metal. The diamond teeth are radially evenly distributed in the resin and are set at the same horizontal plane as the resin. The diamond teeth do not completely cover the radial annularity of the resin.

[0004] While the above solution reduces direct rigid impact and prevents edge chipping by utilizing the elasticity of the resin, in actual use, the outer side of the grinding wheel not only lacks a limiting and protective function, but also fails to generate sufficient heat during operation. This can lead to edge cracking due to insufficient support or poor heat dissipation on the surface of the grinding wheel. Utility Model Content

[0005] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to solve the problems raised in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-chipping abrasive wheel, comprising a wheel body, wherein a first wheel clamping block and a second wheel clamping block are slidably mounted on the inner side of the wheel body, an exhaust groove is provided on the inner side of the second wheel clamping block, a guide groove and a flow groove are provided on the surface of the second wheel clamping block, the guide groove and the flow groove on the second wheel clamping block are interconnected, and the first wheel clamping block is provided with the same exhaust groove, guide groove and flow groove.

[0007] Preferably, the first grinding wheel clamp and the second grinding wheel clamp are in a T-shape.

[0008] Preferably, the grinding wheel body is composed of an abrasive grinding wheel layer and a mesh layer. There are five groups of abrasive grinding wheel layers and four groups of mesh layers. The four groups of mesh layers are respectively set at two adjacent groups of abrasive grinding wheel layers.

[0009] Preferably, a limiting groove is formed on the surface of the grinding wheel body, and a limiting protrusion is slidably installed on the inner wall of the limiting groove on the grinding wheel body. The surface of the limiting protrusion is welded to the surface of the first grinding wheel clamping block.

[0010] Preferably, the second grinding wheel clamping block has a positioning screw groove on its inner side, and the first grinding wheel clamping block is slidably and rotatably mounted with a positioning stud, the surface thread of which is installed on the inner wall of the positioning screw groove on the first grinding wheel clamping block.

[0011] Preferably, the second grinding wheel clamping block is also provided with a limiting protrusion at the contact point with the grinding wheel body, which is connected to the upper limit groove of the grinding wheel body.

[0012] Preferably, a first shaft tube is welded and installed on the inner side of the first grinding wheel clamping block, and a second shaft tube is welded and installed on the inner side of the second grinding wheel clamping block.

[0013] Preferably, the abrasive wheel layer and the mesh layer are bonded together with a resin adhesive.

[0014] Compared with the prior art, the beneficial effects of this utility model are: (1) When the grinding wheel body needs to be replaced, the positioning stud on the first grinding wheel clamping block and the positioning screw groove on the second grinding wheel clamping block are separated. At this time, the first grinding wheel clamping block and the second grinding wheel clamping block are separated from the grinding wheel body. When a new grinding wheel body is replaced, it is reassembled with the first grinding wheel clamping block and the second grinding wheel clamping block. This method ensures that when the grinding wheel body is damaged, the operator can separate the grinding wheel body, the first grinding wheel clamping block and the second grinding wheel clamping block to replace the damaged part. There is no need to discard the traditional whole grinding wheel body, which greatly reduces the waste of resources. Moreover, the grinding wheel body has the characteristics of multi-level layered stamping, heat dissipation during operation, and side limit protection by the shape of the first grinding wheel clamping block and the second grinding wheel clamping block. Therefore, the overall anti-chipping effect of the grinding wheel body is guaranteed, which greatly improves the reliability of the grinding wheel body.

[0015] (2) The anti-chipping abrasive grinding wheel is formed by stamping the grinding wheel body by bonding the mesh sheet layer and the abrasive grinding wheel layer in a cross-shaped manner. This can enhance the strength of the grinding wheel body to a certain extent, thereby reducing the disadvantage of chipping during use due to the poor strength of the traditional single grinding wheel body. Therefore, the grinding wheel body is strengthened by itself and the first grinding wheel clamp and the second grinding wheel clamp cooperate to limit the position, which greatly improves the anti-chipping effect of the grinding wheel body during use.

[0016] (3) When the anti-chipping abrasive wheel is assembled and used by the grinding wheel body, the first grinding wheel clamping block and the second grinding wheel clamping block, when the grinding wheel body generates heat during operation, the heat can be collected and circulated into its interior through the guide groove and flow groove on the first grinding wheel clamping block and the second grinding wheel clamping block, and then exhausted through the exhaust groove on the first grinding wheel clamping block and the second grinding wheel clamping block, thereby reducing the excessive heat generated by the grinding wheel body during operation, thus improving the heat dissipation capacity of the grinding wheel body and ensuring the service life of the grinding wheel body.

[0019] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the description of the textual part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0020] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] In the description of this utility model, terms such as greater than, less than, and exceeding are understood to exclude the stated number, while terms such as above, below, and within are understood to include the stated number. The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0022] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0023] Please see Figure 1-4 This utility model provides a technical solution: an anti-chipping abrasive wheel, including a grinding wheel body 1. A first grinding wheel clamping block 2 and a second grinding wheel clamping block 3 are slidably installed on the inner side of the grinding wheel body 1. The first grinding wheel clamping block 2 and the second grinding wheel clamping block 3 are T-shaped. The T-shape of the first grinding wheel clamping block 2 and the second grinding wheel clamping block 3 ensures that the grinding wheel body 1, when combined with the first grinding wheel clamping block 2 and the second grinding wheel clamping block 3, forms a limiting clamping effect on its side. At the same time, the first grinding wheel clamping block 2 and the second grinding wheel clamping block 3, by virtue of their shape, form a partial covering and protective effect on the side of the grinding wheel body 1, so as to achieve a good barrier effect on the side of the grinding wheel body 1 during use, thereby reducing the disadvantage of chipping the side of the grinding wheel body 1 to a certain extent.

[0024] Furthermore, the grinding wheel body 1 is composed of an abrasive grinding wheel layer 13 and a mesh layer 14. There are five sets of abrasive grinding wheel layers 13 and four sets of mesh layer 14. The four sets of mesh layer 14 are respectively set at the two adjacent sets of abrasive grinding wheel layers 13. The connection between the abrasive grinding wheel layer 13 and the mesh layer 14 is bonded with resin adhesive. By using the mesh layer 14 and the abrasive grinding wheel layer 13 to be cross-bonded and stamped, the strength of the grinding wheel body 1 can be enhanced to a certain extent, so as to reduce the disadvantage of the traditional single grinding wheel body 1 having poor strength and chipping during use. Therefore, the grinding wheel body 1 is reinforced by itself and the first grinding wheel clamp 2 and the second grinding wheel clamp 3 cooperate to limit the movement, which greatly improves the anti-chipping effect of the grinding wheel body 1 during use.

[0025] Furthermore, a limiting groove 4 is formed on the surface of the grinding wheel body 1, and a limiting protrusion 5 is slidably installed on the inner wall of the upper limiting groove 4 of the grinding wheel body 1. The surface of the limiting protrusion 5 is welded to the surface of the first grinding wheel clamping block 2. Similarly, a limiting protrusion 5 is provided at the abutment of the second grinding wheel clamping block 3 with the grinding wheel body 1, which aligns with the upper limiting groove 4 of the grinding wheel body 1. When the grinding wheel body 1 is assembled with the first grinding wheel clamping block 2 and the second grinding wheel clamping block 3, the limiting protrusion 5 on the first grinding wheel clamping block 2 and the second grinding wheel clamping block 3 aligns with the upper limiting groove 4 of the grinding wheel body 1, which can form a snap-fit ​​positioning effect, thus ensuring the stability of the docking and limiting between the grinding wheel body 1 and the first grinding wheel clamping block 2 and the second grinding wheel clamping block 3.

[0026] Furthermore, a first shaft tube 6 is welded and installed on the inner side of the first grinding wheel clamp 2, and a second shaft tube 7 is welded and installed on the inner side of the second grinding wheel clamp 3. The function of the first shaft tube 6 on the first grinding wheel clamp 2 and the second shaft tube 7 on the second grinding wheel clamp 3 is to assist the grinding wheel body 1 in assembling and using with the grinding shaft.

[0027] Furthermore, a positioning screw groove 8 is provided on the inner side of the second grinding wheel clamp 3, and a positioning stud 9 is slidably mounted on the first grinding wheel clamp 2. The surface thread of the positioning stud 9 is installed on the inner wall of the positioning screw groove 8 on the first grinding wheel clamp 2. After the grinding wheel body 1, the first grinding wheel clamp 2 and the second grinding wheel clamp 3 are assembled by docking, the operator controls the positioning stud 9 to be threaded through the positioning screw groove 8 on the first grinding wheel clamp 2 and the second grinding wheel clamp 3, so that the grinding wheel body 1, the first grinding wheel clamp 2 and the second grinding wheel clamp 3 are assembled into a whole for use.

[0028] Furthermore, the inner side of the second grinding wheel clamp 3 is provided with an exhaust groove 10, and the surface of the second grinding wheel clamp 3 is provided with a guide groove 11 and a flow groove 12. The guide groove 11 and the flow groove 12 on the second grinding wheel clamp 3 are interconnected. The first grinding wheel clamp 2 is provided with the same exhaust groove 10, guide groove 11 and flow groove 12. When the grinding wheel body 1, the first grinding wheel clamp 2 and the second grinding wheel clamp 3 are assembled and used, when the grinding wheel body 1 generates heat during operation, the heat can be collected and circulated into its interior through the guide groove 11 and the flow groove 12 on the first grinding wheel clamp 2 and the second grinding wheel clamp 3, and then exhausted through the exhaust groove 10 on the first grinding wheel clamp 2 and the second grinding wheel clamp 3. This reduces the excessive heat generated by the grinding wheel body 1 during operation, thus improving the heat dissipation capacity of the grinding wheel body 1 and ensuring the service life of the grinding wheel body 1.

[0029] Working principle: A chip-resistant abrasive grinding wheel, when in use, the grinding wheel body 1, the first grinding wheel clamping block 2, and the second grinding wheel clamping block 3 can be assembled. After assembly, the positioning stud 9 on the first grinding wheel clamping block 2 and the positioning screw groove 8 on the second grinding wheel clamping block 3 are aligned and positioned, thus assembling the grinding wheel body 1, the first grinding wheel clamping block 2, and the second grinding wheel clamping block 3 into a whole. When the grinding wheel body 1 needs to be replaced, it is only necessary to separate the positioning stud 9 on the first grinding wheel clamping block 2 from the positioning screw groove 8 on the second grinding wheel clamping block 3. At this time, the first grinding wheel clamping block 2 and the second grinding wheel clamping block 3 are separated from the grinding wheel body 1. When a new grinding wheel body 1 is replaced, it is reassembled with the first grinding wheel clamping block 2 and the second grinding wheel clamping block 3 for use.

[0031] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
