Description

Technical Field

[0001] This application relates to the field of grinding equipment, and in particular to a superhard grinding wheel. Background Technology

[0002] In machining processes such as grinding, cutting, and polishing, grinding wheels are typically used to polish workpieces. Currently, grinding wheels usually consist of a base and a zirconia-alumina ring. The zirconia-alumina ring is mounted on the base, and the base drives the zirconia-alumina ring to rotate to polish the workpiece. During the polishing process, the zirconia-alumina ring is prone to damage as the polishing time increases, resulting in a deterioration in polishing quality. In related technologies, replacing the zirconia-alumina ring with a CBN (cubic boron nitride) ring not only improves the service life of the ring but also increases its hardness. However, in the production process, CBN rings typically require a single-piece molding process involving batching, mixing, molding, curing, and post-treatment, which is difficult to manufacture and results in high production costs. Utility Model Content

[0040] Example 1

[0041] like Figure 1 As shown in the figure, this application embodiment provides a superhard grinding wheel, including a base 100, a bonding layer (not shown in the figure), and multiple CBN abrasive blades 200. The bonding layer is laid on the surface of the base 100. The multiple CBN abrasive blades 200 are all installed on the side of the bonding layer facing away from the base 100, and are enclosed to form a ring structure.

[0042] Specifically, in actual production, sanding rings are mostly manufactured using a one-piece molding process. However, during processing, sanding rings inevitably experience machining errors, resulting in them failing to meet processing standards. In such cases, the entire sanding ring needs to be scrapped, leading to increased production costs.

[0043] The superhard grinding wheel provided in this application uses multiple CBN abrasive discs 200 to form a ring structure, avoiding the situation where the entire grinding ring is scrapped due to substandard local quality. Compared with related technologies, this effectively reduces processing difficulty and production costs. The CBN abrasive discs 200 significantly improve hardness and wear resistance compared to related technologies, resulting in better grinding performance. The base 100 facilitates the installation of this device onto external rotary equipment, enabling the multiple CBN abrasive discs 200 to rotate and grind the workpiece. The bonding layer facilitates the installation of multiple CBN abrasive discs 200 onto the base 100, improving the structural stability between the CBN abrasive discs 200 and the base 100, preventing loosening.

[0044] Optionally, the bonding layer may be a resin binder or a ceramic binder.

[0045] In one embodiment of this application, please refer to Figures 1 to 3 The base 100 includes a first base 110 and a second base 120. The second base 120 is detachably mounted on the first base 110 and is used to mount the CBN sand sheet 200.

[0046] Specifically, in practical applications, if the CBN abrasive sheet 200 is damaged, the second substrate 120 can be removed from the first substrate 110, thus removing the damaged CBN abrasive sheet 200 from the external rotating equipment. After removing the second substrate 120 from the first substrate 110, a new CBN abrasive sheet 200, together with the second substrate 120, is installed onto the first substrate 110.

[0047] With this configuration, the first base 110 and the second base 120 adopt a detachable connection design. Compared with related technologies, it is not necessary to replace the entire base 100, which helps to reduce maintenance costs and facilitates maintenance, thus improving the convenience of use.

[0048] In one embodiment of this application, please refer to the following: Figures 1 to 3 The second substrate 120 has an annular groove 121 on the side opposite to the first substrate 110.

[0049] With this configuration, during use, the annular groove 121 can limit the movement of multiple CBN sand sheets 200, preventing them from moving on the surface of the second substrate 120, which helps to further improve the structural stability between the CBN sand sheets 200 and the second substrate 120.

[0050] In one embodiment of this application, see reference Figures 1 to 3The first base 110 has a plurality of first mounting holes 111. The second base 120 has a plurality of second mounting holes 122, and the plurality of second mounting holes 122 and the plurality of first mounting holes 111 are configured in a one-to-one correspondence.

[0051] With this configuration, external bolts can be threaded through the first mounting hole 111 and screwed into the second mounting hole 122, thus fixing the second base 120 to the first base 110. In summary, through multiple first mounting holes 111 and multiple second mounting holes 122, the first base 110 and the second base 120 can be detachably connected with the external bolts, making disassembly and installation convenient.

[0052] In one embodiment of this application, please refer to Figures 1 to 3 The first base 110 has a plurality of mounting posts 112 on the side facing away from the second base 120, and the mounting posts 112 are provided with a third mounting hole 113.

[0053] This configuration allows the first base 110 to be positioned on the external rotating equipment via multiple mounting posts 112, facilitating quick alignment and improving both installation efficiency and convenience. Furthermore, the multiple third mounting holes 113, coupled with external bolts, enable a detachable connection between the first base 110 and the external rotating equipment, simplifying disassembly and installation.

[0054] Example 2

[0055] This embodiment is basically the same as Embodiment 1, except that: in this embodiment, as Figure 1 and Figure 4 As shown, a first groove 210 is provided on the side of the CBN sand sheet 200 facing away from the base 100. The first groove 210 is provided between the inner wall and the outer wall of the CBN sand sheet 200.

[0056] Specifically, during the grinding of a workpiece, a large amount of debris is generated. Due to the presence of debris, it is easy to damage the base 100 and the CBN abrasive disc 200, thereby reducing the service life of the base 100 and the CBN abrasive disc 200.

[0057] With this configuration, when grinding a workpiece, the first groove 210 can discharge debris from the annular structure formed by multiple CBN abrasive discs 200, preventing debris from accumulating in the annular structure and causing damage to the CBN abrasive discs 200, thus helping to extend the service life of the CBN abrasive discs 200 and the base 100.

[0058] In one embodiment of this application, please refer to Figure 4 and Figure 5The CBN abrasive sheet 200 also has a first notch 220, which is connected to the first groove 210 and is located at one end of the first groove 210 near the inner wall of the CBN abrasive sheet 200.

[0059] With this configuration, when grinding the workpiece, the first notch 220 can increase the coverage area of ​​the first groove 210, allowing debris to quickly enter the first groove 210 and facilitating its rapid discharge.

[0060] Example 3

[0061] This embodiment is basically the same as Embodiment 1, except that: in this embodiment, as Figure 6 and Figure 7 As shown, a second groove 230 is provided between any two adjacent CBN sand sheets 200, and the second groove 230 is provided between the inner wall and the outer wall of the CBN sand sheet 200.

[0062] With this configuration, when grinding the workpiece, the second groove 230 can discharge the debris from the annular structure formed by multiple CBN abrasive discs 200, preventing the debris from accumulating in the annular structure and causing damage to the CBN abrasive discs 200, thus helping to extend the service life of the CBN abrasive discs 200 and the base 100.

[0063] In one embodiment of this application, please refer to the following: Figure 6 and Figure 7 Both sides of the CBN abrasive sheet 200 facing away from the base 100 are chamfered 240. The two chamfers 240 between any two adjacent CBN abrasive sheets 200 form a second groove 230.

[0064] Compared to Embodiment 2, this configuration eliminates the need for additional grooves on the surface of the CBN abrasive sheet 200. By using the chamfer 240, it not only ensures normal chip removal from the CBN abrasive sheet 200 but also helps reduce the processing difficulty.

[0065] Example 4

[0066] This embodiment is basically the same as Embodiment 1, except that: in this embodiment, as Figure 8 and Figure 9 As shown, the CBN abrasive sheet 200 has a protrusion 250 and a recess 260. Any two adjacent CBN abrasive sheets 200 are engaged by the protrusion 250 and the recess 260.

[0067] With this configuration, during the grinding process, any two adjacent CBN abrasive sheets 200 can be interlocked through the protrusions 250 and the recesses 260, making the CBN abrasive sheets 200 less prone to loosening. Compared with related technologies, this helps to improve the structural stability between adjacent CBN abrasive sheets 200, thereby further improving the structural stability between the CBN abrasive sheets 200 and the base 100.

[0068] One or more embodiments in this application are intended to cover all such substitutions, modifications, and variations that fall within the broad scope of this application. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of one or more embodiments in this application should be included within the protection scope of this application.
