Description

Technical Field

[0001] The present application relates to the technical field of grinding tools, and in particular to an elastic buffer structure of a superhard grinding wheel. Background Art

[0002] Grinding, cutting, and polishing processes often require the use of grinding wheels to polish workpieces. Currently, grinding wheels typically consist of a base and a CBN abrasive disc. The base is mounted on an external rotary device, and the CBN abrasive disc is mounted on the base. Driven by the external rotary device, the base rotates the CBN abrasive disc to polish the workpiece. During the polishing process, the CBN abrasive disc acts as a working surface, directly contacting the workpiece with friction, generating a strong impact force. This impact force is transmitted to the base through the CBN abrasive disc, which can easily damage the base, resulting in a decrease in the base's rotational accuracy and ultimately poor grinding quality.

[0040] like Figures 1 to 4 As shown, an embodiment of the present application provides an elastic buffer structure for a superhard grinding wheel, comprising a base 100, a CBN (cubic boron nitride) grinding disc 200, and an elastic member 300. The base 100 comprises a first base 110 and a second base 120, which are axially intersecting. 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 elastic member 300 is elastically supported between the first base 110 and the second base 120.

[0041] It should be noted that the axial directions above and below refer to the bidirectional directions of the central axis defined by the structure of the first substrate 110 itself and the structure of the second substrate 120 itself, as shown in FIG. Figure 2 The X-axis shown in .

[0042] The elastic buffer structure of the super-hard grinding wheel provided in the present application can buffer the impact force during the grinding process through the elastic member 300, preventing the impact force from being transmitted to the first base 110 and the external rotating equipment, effectively protecting the first base 110 and the second base 120, and greatly improving the service life of the base 100. In addition, during the grinding process, the elastic member 300 can prevent the first base 110 and the second base 120 from direct contact, which may cause damage to the first base 110 or the second base 120, effectively ensuring the rotation accuracy of the first base 110 and the second base 120, thereby effectively ensuring the rotation accuracy of the CBN sand disc 200, and achieving a good grinding effect. Compared to related technologies, the base 100 is composed of a first base 110 and a second base 120 with a detachable connection design. With the cooperation of the elastic member 300, it can prevent the impact force from being directly transmitted to the external rotating device through the base 100, so that most of the impact force is effectively buffered within the base 100, thereby effectively ensuring the rotation accuracy of the external rotating device. In addition, the first base 110 and the second base 120 adopt a detachable connection design. Compared to related technologies, there is no need to replace the entire base 100, which helps to reduce maintenance costs, facilitates maintenance, and helps to improve ease of use. The use of CBN sand discs 200 and the high hardness of the CBN sand discs 200 help to improve the grinding performance of the grinding wheel and also help to increase the service life of the grinding wheel.

[0043] In one embodiment of the present application, see Figures 1 to 4 At least one first mounting groove 111 is defined on a side of the first base 110 facing the second base 120. The elastic member 300 includes at least one first elastic ring 310, which is engaged in the first mounting groove 111 and elastically supported between the first base 110 and the second base 120. The at least one first elastic ring 310 and the at least one first mounting groove 111 are disposed in a one-to-one correspondence.

[0044] It should be noted that in this embodiment, the number of first mounting grooves 111 and the number of first elastic rings 310 are set to two as an example. Of course, in other embodiments, the number of first mounting grooves 111 and the number of first elastic rings 310 can also be set to one, three, four, or other numbers according to actual application requirements, and this is not a limit here.

[0045] With this arrangement, during the grinding process, the first elastic ring 310 prevents direct contact between the first base 110 and the second base 120, thereby preventing impact forces from acting on the first base 110 and effectively protecting the first base 110 and the external rotating equipment. During the grinding process, the first mounting groove 111 limits the first elastic ring 310, preventing it from shifting between the first base 110 and the second base 120, which could deteriorate the first elastic ring 310's cushioning performance.

[0046] In one embodiment of this application, please refer to Figures 1 to 4 The first base body 110 has a convex ring 112 on one side facing the second base body 120 . The second base body 120 has a ring groove 121 on one side facing the first base body 110 , and the convex ring 112 is snap-fitted into the ring groove 121 .

[0047] With this arrangement, when assembling the first and second base bodies 110, 120, the raised ring 112 and annular groove 121 allow the second base body 120 to be quickly aligned with the first base body 110, thereby improving assembly efficiency. Furthermore, during the polishing process, the raised ring 112 and annular groove 121 can limit the position of the first and second base bodies 110, 120, thereby improving the structural stability between the first and second base bodies 110, 120.

[0048] In one embodiment of the present application, see Figures 1 to 4 The end of the protruding ring 112 away from the first base 110 is provided with a second mounting groove 113 . The elastic member 300 further includes a second elastic ring 320 , which is engaged in the second mounting groove 113 and elastically supported between the protruding ring 112 and the second base 120 .

[0049] With this arrangement, during the grinding process, the second elastic ring 320 prevents direct contact between the protruding ring 112 and the annular groove 121, thereby preventing impact forces from acting on the protruding ring 112 and effectively protecting the first base 110 and the external rotating equipment. The first elastic ring 310, in conjunction with the elastic member 300, further enhances its cushioning performance. During the grinding process, the second mounting groove 113 restrains the second elastic ring 320, preventing it from shifting between the protruding ring 112 and the second base 120, which could degrade its cushioning performance.

[0050] In one embodiment of the present application, see Figures 1 to 4At least one third mounting groove 114 is defined on the outer wall of the protruding ring 112. The elastic member 300 further includes at least one third elastic ring 330, which is engaged in the third mounting groove 114 and elastically abuts between the outer wall of the protruding ring 112 and the second base 120. The at least one third elastic ring 330 corresponds to the at least one third mounting groove 114.

[0051] It should be noted that in this embodiment, the number of third mounting slots 114 and the number of third elastic rings 330 are both set to one. Of course, in other embodiments, the number of third mounting slots 114 and the number of third elastic rings 330 can also be set to two, three, four, or other numbers based on actual application requirements, and this is not a limitation here.

[0052] With this arrangement, during the polishing process, if the first base 110 and the second base 120 tend to move relative to each other, the third elastic ring 330 prevents direct contact between the outer wall of the raised ring 112 and the inner wall of the second base 120. Furthermore, the damping properties of the third elastic ring 330 can block the relative movement of the first and second bases 110, 120, thereby significantly improving the cushioning performance of the elastic member 300. During the polishing process, the third mounting groove 114 can limit the position of the third elastic ring 330, preventing it from shifting between the outer wall of the raised ring 112 and the inner wall of the second base 120, which could degrade its cushioning performance.

[0053] In one embodiment of this application, please refer to 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 122, which are arranged in a one-to-one correspondence with the plurality of first positioning holes 115. The base 100 further includes a plurality of positioning rods 130, one end of each of which is inserted into the first positioning hole 115 and the other end of each of which is inserted into the second positioning hole 122. The plurality of positioning rods 130 and the plurality of second positioning holes 122 are arranged in a one-to-one correspondence.

[0054] It should be noted that in this embodiment, the number of first positioning holes 115, the number of second positioning holes 122, and the number of positioning rods 130 are all set to three. Of course, in other embodiments, the number of first positioning holes 115, the number of second positioning holes 122, and the number of positioning rods 130 can also be set to two, four, five, or other numbers according to actual application requirements, and this is not a limit here.

[0055] With this arrangement, when installing the second base 120, the first positioning hole 115, the second positioning hole 122, and the positioning rod 130 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 122, and the positioning rod 130 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, thereby preventing the rotational accuracy of the CBN sand disc 200 from decreasing, thereby further improving the structural stability between the first base 110 and the second base 120.

[0056] In one embodiment of the present application, see Figures 1 to 4 The elastic member 300 further includes a plurality of first elastic pads 340 , and the plurality of first elastic pads 340 are respectively installed on one end of the plurality of positioning rods 130 close to the first base 110 .

[0057] With such a configuration, during the grinding process, the first elastic pad 340 can prevent the positioning rod 130 and the first base 110 from direct contact, and can prevent the impact force from being transmitted to the first base 110 through the positioning rod 130, which helps to further improve the buffering performance of the elastic member 300.

[0058] In one embodiment of the present application, see Figures 1 to 4 The elastic member 300 further includes a plurality of second elastic pads 350 , and the plurality of second elastic pads 350 are respectively installed on one end of the plurality of positioning rods 130 close to the second base 120 .

[0059] With such a configuration, during the grinding process, the second elastic pad 350 can prevent the positioning rod 130 from directly contacting the second base 120 , and can prevent the impact force from being transmitted to the positioning rod 130 through the second base 120 , which helps to further improve the buffering performance of the elastic member 300 .

[0060] In one embodiment of this application, please refer to Figures 1 to 4 The first base 110 defines a plurality of first mounting holes 116. The second base 120 defines a plurality of second mounting holes 123. The plurality of second mounting holes 123 and the plurality of first mounting holes 116 are disposed in a one-to-one correspondence.

[0061] It should be noted that in this embodiment, the number of first mounting holes 116 and the number of second mounting holes 123 are both set to four. Of course, in other embodiments, the number of first mounting holes 116 and the number of second mounting holes 123 can also be set to two, three, five, or other numbers based on actual application requirements, and this is not a limitation.

[0062] With this arrangement, the second base 120 can be fixed to the first base 110 by threading the external bolts through the first mounting holes 116 and into the second mounting holes 123. In summary, through the multiple first mounting holes 116 and the multiple second mounting holes 123, with the cooperation of the external bolts, the first base 110 and the second base 120 can be detachably connected, making disassembly and installation convenient.

[0063] In one embodiment of the present application, see Figures 1 to 4 The first base 110 has a plurality of mounting posts 117 on a side facing away from the second base 120 , and each of the plurality of mounting posts 117 has a third mounting hole 118 .

[0064] With this arrangement, when the first base 110 is mounted on an external rotating device, the multiple mounting posts 117 allow for positioning of the first base 110, facilitating quick alignment of the first base 110 with the external rotating device, thereby improving installation efficiency and convenience. Furthermore, the multiple third mounting holes 118, coupled with external bolts, allow for a detachable connection between the first base 110 and the external rotating device, facilitating easy installation and removal.

[0065] The one or more embodiments of this application are intended to encompass 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 of this application should be included in the scope of protection of this application.
