Description

Technical Field

[0001] This invention relates to the field of grinding wheel tool technology, and more specifically to a high-speed polishing wheel. Background Technology

[0002] Organic-bonded cup-shaped polishing wheels are limited by the abrasive, filler, pore formation, and bonding strength of the binder inside the wheel. As a result, the wheel has poor rotational strength and the polishing wheel cannot work under high-speed conditions, which greatly limits the efficiency of polishing.

[0003] Current improvement methods mainly focus on increasing the bonding strength of the binder. However, this increased binder strength can lead to a decrease in the elasticity of the polishing wheel, making it prone to burning during use, and the degree of improvement is limited. Furthermore, high-speed, high-efficiency polishing generates significant grinding heat. Increasing the pore size of the polishing wheel contradicts the need to increase strength, making it difficult to balance. It also tends to cause significant elastic deformation of the grinding wheel at high speeds, resulting in an unstable grinding surface. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a high-speed polishing wheel to address the shortcomings of the prior art.

[0005] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: a high-speed polishing wheel, comprising an outer grinding body and an inner grinding body, wherein the outer grinding body comprises an outer ring for grinding, and the inner grinding body comprises an inner ring for grinding, wherein the outer ring surrounds the inner grinding body and is fixed to the outer side of the inner ring, and the upper end surfaces of the outer ring and the inner ring form a grinding surface from the outside to the inside.

[0006] The inner ring is provided with a water tank structure circumferentially for supplying cooling water to the grinding surface.

[0007] The beneficial effects of this invention are as follows: the composite structure of the outer and inner grinding bodies enhances the rotational strength of the polishing wheel. Both the outer and inner grinding bodies have polishing capabilities, and the outer grinding body has high rotational strength, ensuring that the polishing wheel will not crack under certain rotational speed conditions. The bonding strength of the binder is improved by reducing or eliminating the amount of pores inside the polishing wheel. The water tank structure makes it easier for cooling water to act on the grinding surface, improving the cooling effect, thereby achieving high-speed and high-efficiency polishing.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the outer grinding body also includes an outer ring base for stabilizing the inner ring. The outer ring is an open-ended annular frame structure, and the outer ring base is an annular plate structure. The outer diameter of the outer ring is the same as the outer diameter of the outer ring base. The outer diameter edge of the outer ring base is integrally connected to the lower end of the outer ring to form an annular frame structure with an L-shaped longitudinal section.

[0010] The beneficial effects of adopting the above-mentioned further solution are: the outer ring is a continuous ring, which can stabilize the inner grinding body, has high rotational strength, and ensures that the polishing wheel will not crack under certain rotational speed conditions.

[0011] Furthermore, the abrasive particle size of the outer grinding body is larger than that of the inner grinding body, and the wear resistance of the outer grinding body is less than that of the inner grinding body.

[0012] The beneficial effect of adopting the above-mentioned further scheme is that the wear rate of the inner ring is less than or equal to the wear rate of the outer ring, so as to realize rough grinding followed by fine grinding.

[0013] Furthermore, the radial width of the outer ring is less than or equal to 50% of the total radial width of the outer ring and the inner ring (201); the height of the grinding surface located at the outer ring and the inner ring decreases sequentially from the outside to the inside, forming an inclined surface that slopes from the outside to the inside.

[0014] When the product leaves the factory, the entire grinding surface has a pre-set structure with an outer higher and inner lower inclined surface, meaning that the axial height of the outer grinding body is higher than the axial height of the inner grinding body.

[0015] The beneficial effect of adopting the above-mentioned further solution is that: the pre-set grinding surface at a certain angle can offset the axial elastic deformation of the grinding surface caused by the deformation of the inner grinding body due to the high speed of the polishing wheel (that is, the grinding inclined surface is in the axial direction, and the inner grinding body protrudes too much from the outer grinding body), so that the polishing wheel is in a grinding surface that can work normally when in use.

[0016] Furthermore, the inner ring includes multiple L-shaped blocks, each of which is circumferentially stacked and fixed to the inner side of the outer grinding body to form a ring structure; adjacent blocks are tightly abutted, and when the blocks are deformed by force, multiple corresponding first water tank structures are formed circumferentially between each block.

[0017] In other words, when the circumferential deformation of each of the segments is subjected to force, gaps can be formed, thereby forming a first water tank structure. The upper surface of the annular structure forms a grinding working surface, and the water tank structure allows cooling water to reach the grinding working surface.

[0018] The beneficial effect of adopting the above-mentioned further solution is that: when the circumferential deformation of each of the segments is subjected to force, gaps are formed to form a first water tank structure, so that cooling water can easily act on the grinding surface through each first water tank structure.

[0019] Furthermore, the inner ring includes a toothed ring and a toothed ring base. The toothed ring is an annular block structure with open top and bottom, and the toothed ring base is an annular plate structure. The outer diameter of the toothed ring is the same as the outer diameter of the toothed ring base. The outer edge of the toothed ring base is integrally connected to the lower end of the toothed ring. The toothed ring base is fixed to the inner side of the outer grinding body.

[0020] The toothed ring is provided with multiple sets of second water trough structures, which are arranged sequentially and spaced apart along the circumference of the toothed ring; each second water trough structure includes at least two water passages, which are arranged sequentially and spaced apart along the circumference of the toothed ring, and the width of the at least two water passages gradually increases along the radial direction of the toothed ring, and the inner side of the water passage is connected to the inner side of the toothed ring.

[0021] The toothed ring can be pre-formed from multiple sets of second water tank structures in one step, or it can be assembled from multiple sets of second water tank structures.

[0022] The beneficial effect of adopting the above-mentioned further scheme is that multiple sets of second water groove structures are set on the gear ring, so that the cooling water can be easily and evenly applied to the entire grinding surface through each set of second water groove structures.

[0036] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0037] Example 1:

[0038] like Figure 1-11 As shown, a high-speed polishing wheel includes an outer grinding body 1 and an inner grinding body 2. The outer grinding body 1 includes an outer ring 101 for grinding, and the inner grinding body 2 includes an inner ring 201 for grinding. The outer ring surrounds the inner grinding body 2 and is fixed to the outer side of the inner ring. The upper end faces of the outer ring 101 and the inner ring 201 form grinding surfaces from the outside to the inside.

[0039] The inner ring 201 is circumferentially provided with a water tank structure for supplying cooling water to the grinding surface.

[0040] In the above embodiments, the rotational strength of the polishing wheel is enhanced by the composite structure of the outer grinding body 1 and the inner grinding body 2. Both the outer grinding body 1 and the inner grinding body 2 have polishing capabilities. The outer grinding body 1 has high rotational strength, ensuring that the polishing wheel will not crack under certain rotational speed conditions. The bonding strength of the binder is improved by reducing or eliminating the amount of pores inside the polishing wheel. The water tank structure makes it easier for cooling water to act on the grinding surface, improving the cooling effect, thereby achieving high-speed and high-efficiency polishing.

[0041] Specifically, the outer grinding body 1 further includes an outer ring base 102 for stabilizing the inner ring 201. The outer ring 101 is an open-ended annular frame structure, and the outer ring base 102 is an annular plate structure. The outer diameter of the outer ring 101 is the same as the outer diameter of the outer ring base 102. The outer edge of the outer ring base 102 is integrally connected to the lower end of the outer ring 101 to form an annular frame structure with an L-shaped longitudinal section.

[0042] The outer ring is a continuous ring, which can stabilize the inner grinding body and has high rotational strength, ensuring that the polishing wheel will not crack under certain speed conditions.

[0043] Preferably, the abrasive grain size of the outer grinding body 1 is larger than that of the inner grinding body 2, and the wear resistance of the outer grinding body 1 is less than that of the inner grinding body. The outer grinding body 1 and the inner grinding body 2 are composed of a binder, abrasive, and pores; it should be understood that wear resistance here refers to the material's ability to resist mechanical wear.

[0044] This allows the wear rate of the inner ring to be less than or equal to that of the outer ring, enabling rough grinding followed by fine grinding.

[0045] Preferably, the radial width of the outer ring 101 is less than or equal to 50% of the total radial width of the outer ring 101 and the inner ring 201; the height of the grinding surfaces located at the outer ring 101 and the inner ring 201 decreases sequentially from the outside to the inside, forming an inclined surface that slopes from the outside to the inside.

[0046] More preferably, the radial width of the outer ring 101 is set to 15-30% × B, where B is the total radial width of the outer ring 101 and the inner ring 201.

[0047] It should be understood that, at the time of manufacture, the entire grinding surface has a pre-set structure with an outer higher and inner lower inclined surface, that is, the axial height of the outer grinding body is higher than the axial height of the inner grinding body.

[0048] This design ensures that the wear rate of the inner ring 201 is less than or equal to the wear rate of the outer ring 101. The preset grinding surface angle counteracts the elastic protrusion deformation of the grinding surface caused by the high speed of the polishing wheel, allowing the polishing wheel to maintain a relatively stable grinding profile during use. A preset grinding surface angle can also counteract the axial elastic deformation of the grinding surface caused by the deformation of the inner grinding body during high speed of the polishing wheel (i.e., the grinding bevel is present in the axial direction, and the inner grinding body protrudes excessively from the outer grinding body), ensuring that the polishing wheel maintains a working grinding profile during operation.

[0049] Based on Example 1, Example 2:

[0050] like Figure 4-7As shown, one form of the inner grinding body is that the inner ring 201 includes multiple segments 2011 with an L-shaped block structure. Each segment 2011 is sequentially stacked and fixed to the inner side of the outer grinding body 1 to form a ring structure. Two adjacent segments 2011 fit tightly together. When the segments 2011 are deformed by force, the segments 2011 form a corresponding first water tank structure 2012 with circumferential intervals.

[0051] In other words, when the circumferential sections deform under stress, gaps can be formed between them, thus forming the first water tank structure. The upper surface of the annular structure forms the grinding working surface, and the water tank structure allows cooling water to reach the grinding working surface. It should be understood that gaps can be understood as gaps, cracks, or fissures.

[0052] When the circumferential structure between each segment deforms under stress, it forms a gap that constitutes a first water tank structure, allowing cooling water to easily act on the grinding surface through each first water tank structure.

[0053] Preferably, such as Figure 6 As shown, the upper end face of the segment 2011 is inclined from the outside to the inside in a radial direction, and the upper end face of the segment 2011 is also inclined from one side to the other in the circumferential direction, forming an annular sawtooth structure at the grinding surface of the upper end face of the inner ring 201. This can be understood as follows: during high-speed rotation, the axial height of the grinding surface gradually increases from the outer diameter to the inner diameter in the radial direction; under grinding force, the annular grinding surface formed by each segment in the circumferential direction exhibits an alternating sawtooth structure.

[0054] Preferably, such as Figure 6 As shown, the plurality of segments 2011 include first segments and second segments, the plurality of first segments and the plurality of second segments are arranged alternately, the first segments are made of a first material, the second segments are made of a second material, and the hardness of the first material is greater than the hardness of the second material.

[0055] Specifically, in addition to multiple first blocks and multiple second blocks being arranged alternately, multiple first blocks and one second block can also be arranged alternately; or multiple first blocks can form a first block group and multiple second blocks can form a second block group, with the first block group and the second block group being arranged alternately.

[0056] When the upper parts of multiple first-section blocks and multiple second-section blocks are subjected to working force, they form a ring-shaped sawtooth structure. By setting the angle of the grinding working surface, the elastic deformation of the grinding working surface caused by the high speed of the polishing wheel is offset, so that the polishing wheel is in a relatively stable grinding surface, achieving high-speed and high-efficiency polishing.

[0057] Preferably, the first block is made of a first formulation, the second block is made of a second formulation, and the hardness (high rigidity) of the first formulation is higher than that of the second formulation.

[0058] The 2011 segment comes in two types: soft (low rigidity) and hard (high rigidity). The inner ring of the polishing wheel is formed by alternating soft (low rigidity) and hard (high rigidity) segments. When the hard (high rigidity) segment is subjected to force, the whole segment will be squeezed towards the adjacent segment. The softer (low rigidity) adjacent segment has better elastic deformation ability to withstand the squeezing of the harder (high rigidity) segment, forming a displacement deformation "tool yielding" "elastic" effect. The 2011 segment will produce micro-deformation and gaps, making it easier for cooling water to act on the grinding working surface.

[0059] Based on Example 1, Example 3:

[0060] like Figure 8-11 As shown, the second form of the inner grinding body is that the inner ring 201 includes a toothed ring 2013 and a toothed ring base 2014. The toothed ring 2013 is an annular block structure with open top and bottom, and the toothed ring base 2014 is an annular plate structure. The outer diameter of the toothed ring 2013 is the same as the outer diameter of the toothed ring base 2014. The outer edge of the toothed ring base 2014 is integrally connected to the lower end of the toothed ring 2013. The toothed ring base 2014 is fixed to the inner side of the outer grinding body 1.

[0061] Multiple sets of second water trough structures 2015 are provided on the toothed ring 2013. The multiple sets of second water trough structures 2015 are arranged sequentially at intervals along the circumference of the toothed ring 2013. Each second water trough structure 2015 includes at least two water passages. The at least two water passages are arranged sequentially at intervals along the circumference of the toothed ring 2013. The width of the at least two water passages gradually increases along the radial direction of the toothed ring 2013, and the inner side of the water passage is connected to the inner side of the toothed ring 2013.

[0062] The toothed ring can be pre-formed from multiple sets of second water tank structures in one step, or it can be assembled from multiple sets of second water tank structures.

[0063] It should be understood that the gear ring 2013 is a pre-installed whole or is assembled from multiple sets of second water groove structures. Multiple sets of second water groove structures 2015 are provided on the gear ring 2013 so that cooling water can easily act on the grinding surface through each set of second water groove structures 2015.

[0064] Preferably, the height of the upper end face of the toothed ring 2013 gradually decreases from the outside to the inside, forming an inclined grinding working surface.

[0065] It can offset the elastic deformation of the grinding surface caused by the high speed of the polishing wheel by setting the angle of the grinding working surface, so that the polishing wheel is in a relatively stable grinding surface and achieves high-speed and high-efficiency polishing.

[0066] Preferably, such as Figure 11 As shown, the water channel with the largest width along the radial direction of the toothed ring 2013 in each of the second water channel structures 2015 is located near the outer edge of the toothed ring 2013.

[0067] Another scenario is that the water channel with the largest width along the radial direction of the toothed ring 2013 is connected to the outer edge of the toothed ring 2013, that is, the inner ring formed is a through structure.

[0068] Specifically, the number of water channels in each of the second water channel structures 2015 is directly proportional to the cutting depth of the toothed ring 2013.

[0069] It should be understood that when the depth of cut of the gear ring 2013 is greater, the number of water channels in each of the second water channel structures 2015 is greater, thereby improving the uniformity of cooling water flow, ensuring that the cooling water completely covers the entire grinding working surface, meeting the needs of high-speed machining, and improving cooling efficiency and cooling comprehensiveness.

[0070] The difference in width between two adjacent water channels in each of the second water channel structures 2015 along the radial direction of the toothed ring 2013 is inversely proportional to the number of water channels.

[0071] It should be understood that when the depth of cut of the gear ring 2013 is greater, the number of water channels in each of the second water channel structures 2015 is greater, the width difference between two adjacent water channels along the radial direction of the gear ring 2013 is smaller, and the water channel with the smallest width along the radial direction of the gear ring 2013 in each of the second water channel structures 2015 is even smaller; that is, the width of each water channel along the radial direction of the gear ring 2013 decreases as the depth of cut of the gear ring 2013 increases; this allows the cooling water to flow through two or more water channels, covering the outer or inner edge of the gear ring 2013, ensuring that the cooling water completely covers the entire grinding surface, meeting the needs of high-speed machining of cup-shaped wheels, and improving cooling efficiency and comprehensiveness.

[0072] The greater the width of the water passage in each of the second water passage structures 2015 along the radial direction of the toothed ring 2013, the greater the circumferential distance between it and the adjacent water passage.

[0073] The greater the circumferential distance between adjacent water channels, the stronger the grinding workface is in the area between the two adjacent water channels, making the polishing wheel adaptable to high-speed grinding.

[0074] Preferably, in each of the second water trough structures 2015, the distance between the widest water trough along the radial direction of the toothed ring 2013 and the adjacent water trough is W1; the distance between the narrowest water trough along the radial direction of the toothed ring 2013 and the adjacent water trough is W2; and the distance between the narrowest water trough along the radial direction of the toothed ring 2013 and the widest water trough along the radial direction of the toothed ring 2013 in the adjacent second water trough structure 2015 is W3, where W1>W3>W2. By setting W1>W3>W2, the strength of the grinding workface in the area between two adjacent water troughs is ensured, as well as the strength of the grinding workface in the area between two adjacent second water trough structures 2015, allowing the cup-shaped wheel to adapt to high-speed grinding.

[0075] Preferably, the cooling coverage area between the water channel with the largest width along the radial direction of the toothed ring 2013 and the adjacent water channel in each of the second water channel structures 2015 is S1, the cooling coverage area between the water channel with the smallest width along the radial direction of the toothed ring 2 in the second water channel structure 2015 and the adjacent water channel is S2, and the cooling coverage area between the water channel with the smallest width along the radial direction of the toothed ring 2013 in the second water channel structure 2015 and the water channel with the largest width along the radial direction of the toothed ring 2 in the adjacent second water channel structure 2015 is S3, and S1>S3>S2.

[0076] By setting S1>S3>S2, the strength of the area between two adjacent water channels corresponding to the grinding workface is ensured, as well as the strength of the area between two adjacent second water channel structures 2015 corresponding to the grinding workface, so that the cup-shaped wheel can adapt to high-speed grinding.

[0077] Preferably, the water channel with the largest width along the radial direction of the toothed ring 2013 in each of the second water channel structures 2015 is close to the outer edge of the toothed ring 2013.

[0078] The widest water channel along the radial direction of the toothed ring 2013 has one end that is infinitely close to the outer edge of the toothed ring 2013, and the distance between the water channel and the outer edge of the toothed ring 2013 is infinitely close to zero. This allows the cooling water flowing out of the widest water channel along the radial direction of the toothed ring 2013 to cover the outer edge of the toothed ring 2013, thereby improving cooling efficiency.

[0079] Each water passage in each of the second water tank structures 2015 is inclined, and the axis of the water passage is offset from the center of the toothed ring 2013.

[0080] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
