[0046] Example 1

[0047] like Figures 1 to 4 As shown, an embodiment of the present application provides an assembly connection structure for a grinding wheel, comprising a base 100, a CBN (cubic boron nitride) grinding disc 200, and a positioning member 300. The base 100 comprises a first base 110 and a second base 120. The first base 110 is mounted on an external rotary device, and the second base 120 is detachably mounted on the first base 110. The CBN grinding disc 200 is mounted on the side of the second base 120 facing away from the first base 110. The positioning member 300 is disposed between the first base 110 and the second base 120 and is configured to position the second base 120 when the second base 120 is mounted on the first base 110.

[0048] The working principle of this embodiment is as follows: Since the first substrate 110 and the second substrate 120 are detachably connected, when replacing the CBN abrasive disc 200, it is only necessary to remove the second substrate 120 and the CBN abrasive disc 200 from the first substrate 110. After the second substrate 120 and the CBN abrasive disc 200 are removed from the first substrate 110, the new second substrate 120 and the CBN abrasive disc 200 are reinstalled on the first substrate 110 and positioned using the positioning member 300.

[0049] The assembly connection structure of the grinding wheel provided in the present application can replace the CBN sand disc 200 by disassembling and installing the second base 120, which is convenient for disassembly and installation. In addition, the second base 120 can be positioned by the positioning member 300. Compared with the related art, there is no need to disassemble the entire base 100 from the external rotary device, and there is no need to reinstall the base 100 to the external rotary device, which avoids the need to reposition the base 100 and cause a decrease in rotation accuracy, ensures the grinding quality of the grinding wheel, and helps to improve the convenience of use. The use of the CBN sand disc 200 and the high hardness of the CBN sand disc 200 helps to improve the grinding performance of the grinding wheel and also helps to increase the service life of the grinding wheel.

[0050] Optionally, the CBN sand disc 200 is mounted to the second substrate 120 by a resin bond or a vitrified bond.

[0051] In one embodiment of the present application, see Figures 1 to 4One of the first base body 110 and the second base body 120 has an annular groove 121 on its inner wall, and the other has an annular platform 111 , which is engaged in the annular groove 121 .

[0052] With this arrangement, when installing the second base 120, the annular groove 121 and the annular platform 111 can position the second base 120, allowing the second base 120 to be quickly aligned with the first base 110, which helps improve installation convenience and efficiency. During use, the annular groove 121 and the annular platform 111 can limit the second base 120, preventing the second base 120 from sliding radially on the surface of the first base 110, which would reduce the rotational accuracy of the grinding wheel, and help improve the structural stability between the first base 110 and the second base 120.

[0053] In one embodiment of this application, please refer to Figures 1 to 4 The first base 110 defines a plurality of first mounting holes 112. The second base 120 defines a plurality of second mounting holes 122, and the plurality of second mounting holes 122 are arranged in a one-to-one correspondence with the plurality of first mounting holes 112.

[0054] Specifically, in actual use, if the CBN abrasive disc 200 is damaged, the second base 120 can be removed from the first base 110 to remove the damaged CBN abrasive disc 200 from the external rotary device. After the second base 120 is removed from the first base 110, a new CBN abrasive disc 200 is installed on the first base 110 together with the second base 120.

[0055] With this arrangement, the first base 110 and the second base 120 are designed to be detachably connected. Compared to related art, this eliminates the need to replace the entire base 100, helping to reduce maintenance costs, facilitate maintenance, and improve ease of use. External bolts are threaded through the first mounting holes 112 and into the second mounting holes 122 to secure the second base 120 to the first base 110. In summary, through the multiple first mounting holes 112 and the multiple second mounting holes 122, and with the cooperation of external bolts, the first base 110 and the second base 120 can be detachably connected, making disassembly and installation convenient.

[0056] In one embodiment of the present application, see Figures 1 to 4 The first base 110 has a plurality of mounting posts 113 on a side facing away from the second base 120 , and each of the plurality of mounting posts 113 has a third mounting hole 114 .

[0057] With this arrangement, when the first base 110 is mounted on an external rotating device, the multiple mounting posts 113 can be used to position the first base 110, allowing for quick alignment of the first base 110 with the external rotating device, thereby improving installation efficiency and convenience. Furthermore, the multiple third mounting holes 114, coupled with external bolts, allow for a detachable connection between the first base 110 and the external rotating device, facilitating easy installation and removal.

[0058] In one embodiment of the present application, see Figures 1 to 4 The first base 110 defines a plurality of first positioning holes 115. The second base 120 defines a plurality of second positioning holes 123, which are arranged in a one-to-one correspondence with the plurality of first positioning holes 115. The positioning member 300 includes a plurality of first positioning rods 310, one end of each of the first positioning rods 310 being inserted into the first positioning hole 115 and the other end being inserted into the second positioning hole 123. The plurality of first positioning rods 310 and the plurality of second positioning holes 123 are arranged in a one-to-one correspondence.

[0059] The working principle of this embodiment is as follows: when installing the grinding wheel, the first base 110 is first mounted to the external rotary device using the mounting posts 113 and the third mounting holes 114. After the first base 110 is installed, the plurality of first positioning rods 310 are inserted into the plurality of first positioning holes 115. Subsequently, the plurality of second positioning holes 123 on the second base 120 are aligned with the plurality of first positioning rods 310, and the plurality of first positioning rods 310 are inserted into the plurality of second positioning holes 123. After the second base 120 is inserted, the second base 120 is fixed to the first base 110 using external bolts, the first mounting holes 112, and the second mounting holes 122.

[0060] With this arrangement, when installing the second base 120, the first positioning hole 115, the second positioning hole 123, and the first positioning rod 310 can be used to position the second base 120, allowing the second base 120 to be quickly aligned with the first base 110, thereby improving installation convenience and efficiency. Furthermore, during the grinding process, the first positioning hole 115, the second positioning hole 123, and the first positioning rod 310 can limit the position of the first base 110 and the second base 120, preventing the second base 120 from moving radially relative to the first base 110, which would reduce the rotational accuracy of the CBN sand disc 200, and further helping to improve the structural stability between the first base 110 and the second base 120.

[0061] Example 2

[0062] This embodiment is basically the same as the first embodiment, the only difference is that: Figures 5 to 7As shown, any one of the first base body 110 and the second base body 120 is provided with a plurality of third positioning holes 124, and the other is provided with a plurality of second positioning rods 320, which are inserted into the plurality of third positioning holes 124 and correspondingly arranged with the plurality of third positioning holes 124.

[0063] In this way, when the second base body 120 is installed, the second base body 120 can be positioned through the third positioning holes 124 and the second positioning rods 320, so that the second base body 120 is quickly aligned with the first base body 110, which helps to improve the convenience of installation and further improves the installation efficiency. Moreover, during the grinding process, the first base body 110 and the second base body 120 can be limited through the third positioning holes 124 and the second positioning rods 320, so as to prevent the second base body 120 from moving along the radial direction relative to the first base body 110, which causes the rotation accuracy of the CBN grinding wheel 200 to decrease, and further helps to improve the structural stability between the first base body 110 and the second base body 120.

[0064] In an embodiment of the present application, referring to Figures 5 to 7 , the third positioning holes 124 are arranged in a tapered manner along the axial direction from the end close to the second positioning rods 320 to the end away from the second positioning rods 320. The second positioning rods 320 are arranged in a tapered manner along the axial direction from the end away from the third positioning holes 124 to the end close to the third positioning holes 124.

[0065] It should be noted that, in the present embodiment, the third positioning holes 124 are arranged in a tapered manner along the axial direction from the end close to the second positioning rods 320 to the end away from the second positioning rods 320, and the second positioning rods 320 are arranged in a tapered manner along the axial direction from the end away from the third positioning holes 124 to the end close to the third positioning holes 124. Of course, in other embodiments, only the third positioning holes 124 can be arranged in a tapered manner along the axial direction from the end close to the second positioning rods 320 to the end away from the second positioning rods 320. Or, only the second positioning rods 320 can be arranged in a tapered manner along the axial direction from the end away from the third positioning holes 124 to the end close to the third positioning holes 124, which is not limited herein.

[0066] In this way, when the second base body 120 is installed, the second positioning rods 320 can quickly enter the third positioning holes 124 after the third positioning holes 124 are aligned with the second positioning rods 320, which helps to further improve the installation efficiency of the second base body 120.

[0067] Embodiment Three

[0068] The present embodiment is basically the same as Embodiment One, and the difference is that, in the present embodiment, as shown in Figure 2 、 Figures 8 to 10As shown, the first base 110 defines a plurality of first wedge-shaped grooves 116. The second base 120 defines a plurality of second wedge-shaped grooves 125, which are arranged in a one-to-one correspondence with the plurality of first wedge-shaped grooves 116. The positioning member 300 includes a plurality of wedge blocks 330, which are engaged with the first wedge grooves 116 and the second wedge grooves 125, and the plurality of wedge blocks 330 are arranged in a one-to-one correspondence with the plurality of second wedge grooves 125.

[0069] With this arrangement, when installing the second base 120, the first wedge groove 116, the second wedge groove 125, and the wedge block 330 can be used to position the second base 120, allowing the second base 120 to be quickly aligned with the first base 110, thereby improving installation convenience and efficiency. Furthermore, during the grinding process, the first wedge groove 116, the second wedge groove 125, and the wedge block 330 can limit the position of the first base 110 and the second base 120, preventing the second base 120 from moving radially relative to the first base 110, which would reduce the rotational accuracy of the CBN sanding disc 200, and further helping to further improve the structural stability between the first base 110 and the second base 120.

[0070] In one embodiment of this application, please refer to Figure 2 、 Figures 8 to 10 The first wedge-shaped groove 116 is configured to taper from one end near the inner wall of the first base body 110 toward one end of the outer wall of the first base body 110. The second wedge-shaped groove 125 is configured to taper from one end near the inner wall of the second base body 120 toward one end of the outer wall of the second base body 120. The wedge-shaped block 330 is configured to taper from one end near the inner wall of the first base body 110 toward one end of the outer wall of the first base body 110.

[0071] Such a configuration can prevent the wedge block 330 from escaping from the first wedge groove 116 and the second wedge groove 125, so that the wedge block 330 can stably limit the first base 110 and the second base 120, which helps to further improve the structural stability between the first base 110 and the second base 120.
