[0061] 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.

[0062] Example 1:

[0063] like Figures 1 to 11As shown, an assembled grinding tool includes a base 1 and multiple tooth assemblies 2. The base 1 has an annular fixing groove 101. The multiple tooth assemblies 2 are stacked along the fixing groove 101 to form an annular structure. One end of each tooth assembly 2 extends into the base 1 and is embedded in the fixing groove 101, while the other end extends outward from the base 1 to form a grinding end. Each tooth assembly 2 is fixedly connected to its adjacent tooth assembly 2 and the base 1 via an auxiliary component 3. The auxiliary component 3 is made of a high-strength metal material, such as steel or copper.

[0064] Furthermore, the tooth assembly 2 includes a first tooth 201 and a second tooth 202. The ends of the first tooth 201 and the second tooth 202 that are embedded in the fixing groove 101 are fixedly connected to an auxiliary member 3. The first tooth 201 and the second tooth 202 are fixedly connected to the adjacent tooth assembly 2 and the base 1 respectively through the auxiliary member 3.

[0065] The auxiliary component 3 is fixedly connected to the first tooth body 201 or the second tooth body 202 by adhesive, and the auxiliary component 3 is provided with multiple through holes 301, concave points 302 or hollow protrusions 303, and the multiple through holes 301, concave points 302 or hollow protrusions 303 are all filled with adhesive.

[0066] Specifically, the grinding end formed by the ends of the multiple tooth groups 2 away from the center of the base 1 is annular, and the ends of the multiple tooth groups 2 near the center of the base 1 are all embedded in the fixing groove 101 and fixedly connected to the base 1, thereby enhancing the connection strength between the tooth groups 2 and the base 1; the tooth groups 2 are fixedly connected to each other by auxiliary parts 3 and glue, increasing the glue bonding area between the tooth groups 2, thereby improving the connection strength between the tooth groups 2 and the connection strength between the tooth groups 2 and the base 1, ensuring the high rotational strength or heavy-duty grinding of the assembled grinding wheel.

[0067] Furthermore, by arranging perforations 301, recesses 302, or hollow protrusions 303 on the auxiliary component 3, more adhesive is injected between the auxiliary component 3 and the first tooth 201 or the second tooth 202, and the adhesive bonding area between the auxiliary component 3 and the first tooth 201 or the second tooth 202 is expanded. This increases the adhesive bonding strength and mechanical restraint, improves the connection strength between the auxiliary component 3 and the first tooth 201 or the second tooth 202, and further improves the connection strength between the tooth assembly 2 and the connection strength between the tooth assembly 2 and the base 1 through the auxiliary component 3. This improves the connection strength of the assembled grinding wheel, significantly increases the rotational strength, and makes the assembled grinding wheel suitable for high linear speed machining, which is beneficial for precision and efficient grinding.

[0068] Multiple tooth groups 2 are stacked to form a ring structure, which reduces or eliminates hole making in the composite grinding wheel, greatly improves the strength of the composite grinding wheel, and also has a better cooling effect and rapid chip removal; it also greatly reduces the grinding load under the same conditions, and can also reduce the requirements for connection strength or increase the space for high-efficiency grinding.

[0069] In the above embodiments, such as Figure 10 and 11 As shown, the auxiliary component 3 has a dovetail tenon structure, and the auxiliary component 3 can also engage with the base 1 through interlocking, dovetail, concave and convex structures.

[0070] The auxiliary component 3 has a dovetail tenon structure and matches the structure of the fixing groove 101. The fixing groove 101 is used to fix the auxiliary component 3, thereby enhancing the connection strength between the auxiliary component 3 and the base 1. The adhesive connection between the auxiliary component 3 and the first tooth 201 or the second tooth 202 can further enhance the connection strength between the tooth assembly 2 and the connection strength between the tooth assembly 2 and the base 1.

[0071] In the above embodiment, a water channel 4 is provided between the first tooth body 201 and the second tooth body 202 to guide the cooling water to the grinding end.

[0072] In the above embodiment, grooves 401 arranged radially along the base 1 are provided on both end sidewalls of the first tooth body 201 and the second tooth body 202. The grooves 401 on the first tooth body 201 and the grooves 401 on the second tooth body 202 are combined to form the water passage trough 4.

[0073] The upper end of the base 1 is provided with a cooling water inlet to introduce cooling water, which is discharged through the water channel 4 to the grinding ends of the multiple tooth assemblies 2, thereby improving the cooling effect of the grinding ends and rapid chip removal. Under the same conditions, the grinding load is greatly reduced, and the requirements for the connection strength of the tooth assemblies 2 can also be reduced, making the grinding more efficient.

[0074] In the above embodiments, the ends of the first tooth 201 and the second tooth 202 that are embedded in the fixing groove 101 are both dovetail tenon structures and match the structure of the fixing groove 101.

[0075] By matching the structure of the first tooth 201 and the second tooth 202 embedded in the fixed groove 101, the connection strength between the first tooth 201 and the second tooth 202 and the base 1 is enhanced, thereby enabling the assembled grinding wheel to meet the strength requirements of high-speed grinding.

[0076] In the above embodiment, a pressure plate 5 is fixedly disposed on the base 1 to press the multiple tooth assemblies 2. The pressure plate 5 presses the multiple tooth assemblies 2 into the fixing groove 101, making the assembled grinding wheel stronger and suitable for high-speed grinding.

[0077] Example 2:

[0078] like Figures 12 to 21 As shown, an assembled grinding tool includes a base 1 and multiple tooth assemblies 2. The base 1 has an annular fixing groove 101. The multiple tooth assemblies 2 are stacked along the fixing groove 101 to form an annular structure. One end of each tooth assembly 2 is embedded in the fixing groove 101, and the other end forms a grinding end. Each tooth assembly 2 is fixedly connected to its adjacent tooth assembly 2 and the base 1 via an auxiliary component 3. The auxiliary component 3 is made of a high-strength metal material, such as steel or copper.

[0079] Furthermore, the tooth assembly 2 includes a first tooth 201 and a second tooth 202. The ends of the first tooth 201 and the second tooth 202 that are embedded in the fixing groove 101 are fixedly connected to auxiliary components 3. The first tooth 201 and the second tooth 202 are fixedly connected to the adjacent tooth assembly 2 and the base 1 respectively through the auxiliary components 3.

[0080] Furthermore, the end of the first tooth 201 that is embedded in the fixing groove 101 is fixedly connected to the end of the second tooth 202 that is embedded in the fixing groove 101 through the auxiliary member 3.

[0081] In the above embodiments, the auxiliary component 3 is fixedly connected to the first tooth 201 or the second tooth 202 by adhesive, and the auxiliary component 3 is provided with a plurality of through holes 301 or protrusions 303, and the plurality of through holes 301 are filled with adhesive. Figure 17 , Figure 18 and Figure 19 As shown, the auxiliary component 3 is in close contact with the first tooth body 201 through multiple protrusions 303, or the multiple protrusions 303 on the auxiliary component 3 are away from the first tooth body 201.

[0082] Specifically, the upper ends of the multiple tooth assemblies 2 form a ring-shaped grinding end, and the lower ends of the multiple tooth assemblies 2 are all embedded in the fixing groove 101 and fixedly connected to the base 1, thereby enhancing the connection strength between the tooth assemblies 2 and the base 1; the tooth assemblies 2 are fixedly connected to each other by auxiliary parts 3 and glue, increasing the glue bonding area between the tooth assemblies 2, thereby improving the connection strength between the tooth assemblies 2 and the connection strength between the tooth assemblies 2 and the base 1, ensuring the high-speed rotational strength or heavy-duty grinding of the assembled grinding wheel.

[0083] Furthermore, by arranging perforations 301 or protrusions 303 on the auxiliary component 3, more adhesive is injected between the auxiliary component 3 and the first tooth 201 or the second tooth 202, and the adhesive bonding area between the auxiliary component 3 and the first tooth 201 or the second tooth 202 is expanded. This increases the adhesive bonding strength and mechanical restraint, improves the connection strength between the auxiliary component 3 and the first tooth 201 or the second tooth 202, and the connection strength between the tooth assembly 2. The improved connection strength of the first tooth 201 and the second tooth 202 further improves the connection strength between the tooth assembly 2 and the connection strength between the tooth assembly 2 and the base 1 through the auxiliary component 3. This improves the connection strength of the assembled grinding wheel, significantly increases the rotational strength, and makes the assembled grinding wheel suitable for high linear speed machining, which is beneficial for precision and efficient grinding.

[0084] Multiple tooth groups 2 are stacked to form a ring structure, which reduces or eliminates hole making in the composite grinding wheel, greatly improves the strength of the composite grinding wheel, and also has a better cooling effect and rapid chip removal; it also greatly reduces the grinding load under the same conditions, and can also reduce the requirements for connection strength or increase the space for high-efficiency grinding.

[0085] In the above embodiment, a water channel 4 is provided between the first tooth body 201 and the second tooth body 202 to guide the cooling water to the grinding end.

[0086] In the above embodiments, the sidewalls of the first tooth body 201 and the second tooth body 202 are provided with a horizontal water groove 402 and a vertical water groove 403. The horizontal water groove 402 is arranged radially along the base 1, and the vertical water groove 403 is arranged axially along the base 1. The horizontal water groove 402 and the vertical water groove 403 are arranged in a cross pattern to form the water passage 4.

[0087] During the grinding process of the first tooth body 201 and the second tooth body 202, cooling water is introduced into the water inlet at the bottom of the base 1. The cooling water is guided to the grinding end through the horizontal water tank 402 and the vertical water tank 403, which improves the cooling effect of the grinding end and the rapid chip removal. Under the same conditions, the grinding load is greatly reduced, and the requirements for the connection strength of the tooth body assembly 2 can also be reduced, making the grinding more efficient.

[0088] In the above embodiment, the ends of the first tooth 201 and the second tooth 202 that are embedded in the fixing groove 101 are structurally matched with the fixing groove 101.

[0089] By matching the structure of the first tooth 201 and the second tooth 202 embedded in the fixed groove 101, the connection strength between the first tooth 201 and the second tooth 202 and the base 1 is enhanced, thereby enabling the assembled grinding wheel to meet the strength requirements of high-speed grinding.

[0090] In the above embodiment, a pressure plate 5 is fixedly disposed on the base 1 to press the multiple tooth assemblies 2. The pressure plate 5 presses the multiple tooth assemblies 2 into the fixing groove 101, making the assembled grinding wheel stronger and suitable for high-speed grinding.
