Description

Technical Field

[0001] This invention relates to the field of polishing wheel technology, and more particularly to a polishing wheel with an auxiliary device. Background Technology

[0002] In the prior art, polishing wheels with organic binders are usually moderately elastic. Due to the limitations of the abrasive, filler, pore formation and bonding strength of the binder inside the polishing wheel, the rotational strength of the polishing wheel is poor, and the polishing wheel is difficult to 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 amount of pores created to improve heat resistance by increasing the water absorption capacity of the polishing wheel's chips contradicts the need for increased strength, making it difficult to address. This also tends to cause significant elastic deformation of the polishing wheel at high speeds, leading to deformation and instability of the polishing wheel's grinding end face.

[0004] In the existing technology, polishing wheels are also clamped by a ring device to increase the strength of the polishing wheel and enable it to work under high speed conditions. However, the ring device has high structural strength but no polishing ability. When the wear rate is lower than that of the polishing wheel, the ring device is prone to interference during the polishing process of the polishing wheel on the workpiece, which affects the normal operation of the polishing wheel. Summary of the Invention

[0005] The present invention aims to at least partially solve one of the aforementioned technical problems in the prior art. Therefore, one object of the present invention is to provide a polishing wheel with an auxiliary device for achieving high-speed, high-efficiency polishing.

[0006] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A polishing wheel with an auxiliary device includes a base plate, an outer ring and an abrasive ring. The outer ring and the abrasive ring are both fixedly placed on the base plate, and the outer ring is fixedly fitted on the abrasive ring. The abrasive ring is provided with a plurality of water channels to guide cooling water to its grinding end face. A first turning tool fixedly connected to an external machine tool is provided on one side of the outer ring, and the first turning tool turns the outer ring.

[0007] The beneficial effects of this invention are: by using the outer ring to tightly fasten the abrasive ring, the rotational strength of the abrasive ring is improved, and high-speed, high-efficiency polishing is achieved; by using the first cutting tool to turn the outer ring during the polishing operation of the abrasive ring, the abrasive ring has a slight extension relative to the outer ring, which is suitable for polishing work with low stress, low heat, and high precision under high-speed conditions.

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

[0009] Furthermore, an inner ring with interference fit is fixedly provided inside the abrasive ring, and a second cutting tool fixedly connected to an external machine tool is provided on one side of the inner ring, the second cutting tool turning the inner ring.

[0010] The beneficial effects of adopting the above-mentioned further scheme are: the outer ring and the inner ring are used to radially clamp and secure the abrasive ring, thereby improving the rotational strength of the abrasive ring and achieving high-speed and high-efficiency polishing; the second cutting tool is used to turn the inner ring during the polishing operation of the abrasive ring, so that the abrasive ring has a slight extension relative to the inner ring, which is suitable for working under high-speed conditions.

[0011] Furthermore, the abrasive ring includes multiple segments arranged radially along the outer ring, and the multiple segments are sequentially attached to form a ring structure; the multiple segments are fixedly connected to the outer ring and the inner ring, and a water channel is formed between two adjacent segments.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the water channel introduces cooling water into the grinding end face of the abrasive ring, which can cool the grinding end face of the abrasive ring and improve the cooling efficiency.

[0013] Furthermore, a middle ring for fixing multiple segments is fixedly arranged inside the abrasive ring, and a third cutting tool fixedly connected to an external machine tool is provided on one side of the middle ring, and the third cutting tool turns the middle ring.

[0014] The beneficial effects of adopting the above-mentioned further solution are: using the middle ring to fasten the abrasive ring, improving the rotational strength of the abrasive ring, and achieving high-speed and high-efficiency polishing; using the third cutting tool to turn the inner ring during the polishing operation of the abrasive ring, so that the abrasive ring has a slight extension relative to the middle ring, so as to be suitable for working under high-speed conditions.

[0015] Furthermore, during the polishing process of the workpiece by the abrasive ring, the first turning tool, the second turning tool, and the third turning tool respectively turn the outer ring, the inner ring, and the middle ring, and the abrasive ring protrudes from the outer ring, the inner ring, and the middle ring along its axial direction to form a slight protrusion, thereby performing the polishing work.

[0016] Furthermore, the width of the outer ring at the end away from the base plate is greater than the width of the ring at the end closer to the base plate; the width of the inner ring at the end away from the base plate is greater than the width of the ring at the end closer to the base plate; and the width of the middle ring at the end away from the base plate is greater than the width of the ring at the end closer to the base plate.

[0017] The beneficial effect of adopting the above-mentioned further solution is that it can suppress the axial displacement and deformation of the abrasive ring.

[0018] Furthermore, a manifold and a pressure plate fitted on the manifold are fixedly disposed on the base plate of the substrate. The manifold is located inside the inner ring, and the pressure plate presses the manifold, the inner ring, and the abrasive ring onto the base plate of the substrate.

[0019] The beneficial effects of adopting the above-mentioned further solution are: the pressure plate is used to fix the manifold, inner ring and abrasive ring on the base plate, and the outer ring and inner ring are used to limit and fix the abrasive ring, making the abrasive ring more stable, so that the polishing wheel is in a more stable grinding state during the grinding process, and high-speed and high-efficiency polishing is achieved.

[0020] Furthermore, both the outer ring and the inner ring are provided with multiple chip-breaking groups to break up the waste chips generated during the turning of the outer ring, and the multiple chip-breaking groups are arranged along the axial direction of the outer ring and the inner ring.

[0021] Furthermore, each of the chip-breaking groups includes multiple slots, which are arranged sequentially at intervals along the circumference of the outer and inner rings.

[0022] The beneficial effects of adopting the above-mentioned further solution are: the slot breaks up the chips generated during the turning process, preventing the chips from wrapping around the cutting tool, while ensuring that the outer and inner rings have sufficient strength.

[0041] 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.

[0042] Example 1:

[0043] like Figure 1 As shown, a polishing wheel with an auxiliary device includes a base plate 1, an outer ring 2, and an abrasive ring 3. Both the outer ring 2 and the abrasive ring 3 are fixedly mounted on the base plate 1, with the outer ring 2 fixedly fitted onto the abrasive ring 3. The abrasive ring 3 has multiple water channels 4 inside to guide cooling water flow to its grinding end face. A first cutting tool 5, fixedly connected to an external machine tool, is provided on one side of the outer ring 2. The first cutting tool 5 turns the outer ring 2. During the polishing process of the workpiece 12, the first cutting tool 5 turns the outer ring 2, and the abrasive ring 3 protrudes axially from the outer ring 2.

[0044] The outer ring 2 is made of an organic material that is easy to cut or grind, or a composite material or metal material with fibers, such as nylon, rubber material containing cord fabric, aluminum or aluminum alloy material; the outer ring 2 can protect the abrasive ring 3 to have high rotational strength and can withstand the abrasive ring 3 under the action of grinding force and centrifugal force without breaking, ensuring that the polishing wheel avoids the phenomenon of bursting under the set speed conditions; the base plate 1 is provided with a groove corresponding to the outer ring 2, and the lower end of the outer ring 2 is fixedly placed in the groove;

[0045] In this embodiment, the outer ring 2 is used to tightly fasten the abrasive ring 3, thereby increasing the strength of the abrasive ring 3. This not only allows for the arrangement of dense water channels inside the abrasive ring 3 to guide cooling water to the grinding end face of the abrasive ring 3, improving the cooling effect of the abrasive ring 3, but also reduces or eliminates the amount of pores inside the polishing wheel grinding ring, increasing the bonding strength of the binder. This ensures that the rotational strength of the abrasive ring 3 meets the usage conditions, keeping the polishing wheel in a relatively stable grinding state during the grinding process, and achieving high-speed and high-efficiency polishing.

[0046] A tool holder fixed to an external machine tool is installed at an appropriate position on the polishing equipment. The first cutting tool 5 is fixed on the tool holder and can perform turning machining on the outer ring 2. The contact position between the cutting edge of the first cutting tool 5 and the outer ring 2 is on the side where the abrasive ring 3 extends slightly closer to the base plate 1. When the polishing wheel is feeding, as the abrasive ring 3 is consumed, the first cutting tool 5 cuts the outer ring 2, ensuring that the slight extension of the abrasive ring 3 is greater than the compression deformation of the abrasive ring 3 during polishing, thus ensuring that the slight extension of the abrasive ring 3 is constant, and further ensuring the safe and normal operation of the polishing wheel. When the outer ring 2 is made of fibrous material and is not suitable for turning, the cutting tool can be replaced with a diamond grinding block to grind the outer ring 2.

[0047] During the polishing process of the abrasive ring 3, the outer ring 2 is machined using the first cutting tool 5, so that the abrasive ring 3 has a slight extension relative to the outer ring 2. The outer ring 2 can ensure the rotational strength of the extended part of the abrasive ring 3, thereby improving the rotational strength of the abrasive ring 3 to be suitable for working under high speed conditions.

[0048] In the above embodiment, the abrasive ring 3 includes a plurality of segments 3.1, which are arranged radially along the outer ring 2 and are sequentially attached to form a ring structure; the plurality of segments 3.1 are all fixedly connected to the outer ring 2, and a water channel 4 is formed between two adjacent segments 3.1.

[0049] The base plate 1 is used to fix multiple segments 3.1 with a binder, and the outer ring 2 is also used to fix multiple segments 3.1, making the abrasive ring 3 composed of multiple segments 3.1 more stable;

[0050] During the grinding process of the workpiece 12, the water channel 4 introduces cooling water into the grinding end face of the abrasive ring 3, which can cool the grinding end face of the abrasive ring 3, improve cooling efficiency, reduce cooling water waste, and also help maintain the strength of the polishing wheel.

[0051] In the above embodiment, the outer ring 2 is provided with a plurality of chip-breaking groups 11 for breaking the waste chips generated during the turning of the outer ring 2, and the plurality of chip-breaking groups 11 are arranged along the axial direction of the outer ring 2. Each chip-breaking group 11 surrounds the outer ring 2.

[0052] In the above embodiments, each chip-breaking group 11 includes a plurality of slots 11.1, which are arranged sequentially at intervals along the circumference of the outer ring 2.

[0053] During the turning process of the first cutting tool 5 on the outer ring 2, after turning one end of the outer ring 2, the first cutting tool 5 will encounter the slot 11.1. The slot 11.1 will break the waste generated during the turning process, so as to prevent the waste generated during the turning process from getting entangled in the first cutting tool 5, while ensuring that the outer ring 2 has sufficient strength.

[0054] Example 2:

[0055] like Figure 2 and Figure 3 As shown, in this embodiment, based on Embodiment 1, an inner ring 6 is fixedly disposed inside the abrasive ring 3, which is press-fitted to the inner wall of the abrasive ring 3. A second cutting tool 7, which is fixedly connected to an external machine tool, is disposed on one side of the inner ring 6. The second cutting tool 7 turns the inner ring 6. During the polishing process of the workpiece 12 by the abrasive ring 3, the second cutting tool 7 turns the inner ring 6, and the abrasive ring 3 protrudes from the inner ring 6 along its axial direction.

[0056] The inner ring 6 is used to press the abrasive ring 3 with an interference fit, which works simultaneously with the outer ring 2 to achieve radial clamping of the abrasive ring 3, making the abrasive ring 3 more stable and ensuring that the rotational strength of the abrasive ring 3 meets the usage conditions. This keeps the polishing wheel in a relatively stable grinding state during the grinding process, achieving high-speed and high-efficiency polishing.

[0057] A tool post fixed to an external machine tool is installed at an appropriate position on the polishing equipment. The second cutting tool 7 is fixed on the tool post and can perform turning machining on the inner ring 6. The contact position between the cutting edge of the second cutting tool 7 and the inner ring 6 is on the side where the abrasive ring 3 extends slightly closer to the base plate 1. When the polishing wheel is feeding, as the abrasive ring 3 is consumed, the second cutting tool 7 cuts the inner ring 6 to ensure that the slight extension of the abrasive ring 3 is greater than the compression deformation of the abrasive ring 3 during polishing, thus ensuring that the slight extension of the abrasive ring 3 is constant and further ensuring the safe and normal operation of the polishing wheel. When the inner ring 6 is made of fibrous material and is not suitable for turning, the cutting tool can be replaced with a diamond grinding block to grind the inner ring 6.

[0058] During the polishing process of the abrasive ring 3, the inner ring 6 is machined using the second cutting tool 7, so that the abrasive ring 3 protrudes slightly from the inner ring 6. The inner ring 6 can ensure the rotational strength of the protruding part of the abrasive ring 3, thereby improving the rotational strength of the abrasive ring 3 to make it suitable for high-speed operation.

[0059] In the above embodiment, the abrasive ring 3 includes a plurality of segments 3.1, which are arranged radially along the outer ring 2 and are sequentially attached to form a ring structure; the plurality of segments 3.1 are fixedly connected to the outer ring 2 and the inner ring 6, and a water channel 4 is formed between two adjacent segments 3.1.

[0060] The base plate 1 is used to fix multiple segments 3.1 with a binder, and the outer ring 2 and inner ring 6 are also used to fix the multiple segments 3.1, making the abrasive ring 3 composed of multiple segments 3.1 more stable.

[0061] In the above embodiment, a manifold 9 and a pressure plate 10 fitted on the manifold 9 are fixedly provided on the base plate 1. The manifold 9 is located inside the inner ring 6, and the pressure plate 10 presses the manifold 9, the inner ring 6 and the abrasive ring 3 onto the base plate 1.

[0062] The manifold 9, inner ring 6 and abrasive ring 3 are fixed on the base plate 1 using the pressure plate 10. The outer ring 2 and inner ring 6 are used to limit and fix the abrasive ring 3, making the abrasive ring 3 more stable and ensuring that the rotational strength of the abrasive ring 3 meets the usage conditions. This allows the polishing wheel to be in a relatively stable grinding state during the grinding process, achieving high-speed and high-efficiency polishing.

[0063] In the above embodiment, the inner ring 6 is provided with a plurality of chip breaking groups 11 for breaking the waste chips generated during the turning of the outer ring 2, and the plurality of chip breaking groups 11 are arranged along the axial direction of the outer ring 2.

[0064] In the above embodiments, each chip-breaking group 11 includes a plurality of slots 11.1, which are arranged sequentially at intervals along the circumference of the outer ring 2.

[0065] During the turning process of the second cutting tool 7 on the inner ring 6, after turning one end of the inner ring 6, the second cutting tool 7 will encounter the slot 11.1. The slot 11.1 will break the waste generated during the turning process, so as to prevent the waste generated during the turning process from getting entangled in the second cutting tool 7, while ensuring that the inner ring 6 has sufficient strength.

[0066] Example 3:

[0067] like Figure 4 and Figure 5 As shown, in this embodiment, based on embodiment 2, a middle ring 8 is fixedly arranged inside the abrasive ring 3, which fixes multiple segments 3.1. A third cutting tool is fixedly connected to an external machine tool on one side of the middle ring 8, and the third cutting tool turns the middle ring 8. During the polishing process of the workpiece 12 by the abrasive ring 3, the third cutting tool turns the middle ring 8, and the abrasive ring 3 protrudes from the outer ring 2 along its axial direction.

[0068] A tool post fixed to an external machine tool is installed at an appropriate position on the polishing equipment. The third cutting tool is fixed on the tool post and can be used to perform turning of the middle ring 8. The contact position between the cutting edge of the third cutting tool and the middle ring 8 is on the side where the abrasive ring 3 extends slightly closer to the base plate 1. When the polishing wheel is feeding, as the abrasive ring 3 is consumed, the third cutting tool will cut the middle ring 8 to ensure that the slight extension of the abrasive ring 3 is greater than the compression deformation of the abrasive ring 3 during polishing, thus ensuring that the slight extension of the abrasive ring 3 is constant and further ensuring the safe and normal operation of the polishing wheel. When the middle ring 8 is made of fibrous material and is not suitable for turning, the cutting tool can be replaced with a diamond grinding block to grind the middle ring 8.

[0069] During the polishing process of the abrasive ring 3, the middle ring 8 is machined using the third cutting tool, so that the abrasive ring 3 protrudes slightly from the middle ring 8. The middle ring 8 can ensure the rotational strength of the protruding part of the abrasive ring 3, thereby improving the rotational strength of the abrasive ring 3 to make it suitable for high-speed operation.

[0070] The abrasive ring 3 includes two sets of segments 3.1, each set of segments 3.1 including multiple segments 3.1. One set of segments 3.1 is located between the outer ring 2 and the middle ring 8, and the other set of segments 3.1 is located between the middle ring 8 and the inner ring 6. The multiple segments 3.1 in each set of segments 3.1 are arranged radially along the outer ring 2, and the multiple segments 3.1 are sequentially and tightly attached to form a ring structure, and a water channel 4 is formed between two adjacent segments 3.1.

[0071] In the above embodiments, the width of the outer ring 2 at the end away from the base plate 1 is greater than the width of the end close to the base plate 1; the width of the inner ring 6 at the end away from the base plate 1 is greater than the width of the end close to the base plate 1; and the width of the middle ring 8 at the end away from the base plate 1 is greater than the width of the end close to the base plate 1.

[0072] To further suppress axial displacement of the abrasive ring 3, an inner ring 6 with a large interference fit is fixedly installed on the inner wall of the abrasive ring. The longitudinal section of the abrasive ring 3 is trapezoidal and the ring width at the upper end is the smallest. The side wall shapes of the outer ring 2 and the inner ring 6 correspond to the side shape of the abrasive ring 3, forming a semi-dovetail structure, thereby suppressing axial displacement and deformation of the abrasive ring 3.

[0073] In the above embodiment, multiple middle rings 8 are provided, and each middle ring 8 is located between the outer ring 2 and the inner ring 6; the multiple middle rings 8 are arranged concentrically, and adjacent middle rings 8 are arranged at intervals; multiple segments 3.1 are provided between each pair of middle rings 8, and the multiple segments 3.1 are sequentially attached to form a ring structure; the multiple segments 3.1 are fixedly connected to two adjacent middle rings 8, and a water channel 4 is formed between two adjacent segments 3.1; this is used to accommodate polishing wheels or polishing discs with a large ring width, so that the polishing wheels or polishing discs can adapt to high-speed processing.

[0074] When machining with a polishing wheel or polishing disc, if the grinding end face of the polishing wheel or polishing disc is in contact with the workpiece and a turning tool cannot be installed, and the spindle of the machine tool is movable, such as the spindle of a machining center, the tool holder and turning tool can be set on the machine tool. The turning tool is used to periodically turn the outer ring 2, inner ring 6, and middle ring 8. After turning with the turning tool, the workpiece is polished using the outer ring 2, inner ring 6, and middle ring 8 for one cycle. Then, the turning tool is used to turn the outer ring 2, inner ring 6, and middle ring 8 again, and the workpiece is polished using the outer ring 2, inner ring 6, and middle ring 8 for another cycle. This process is repeated.

[0075] 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.
