Description

Technical Field

[0001] This utility model relates to the field of grinding technology, specifically to an environmentally friendly resin grinding wheel. Background Technology

[0002] Resin grinding wheels are a commonly used grinding tool, made by mixing and pressing abrasive with resin binder. They are characterized by high grinding efficiency and stable precision, and are widely used in machining, automobile manufacturing, metal products and other fields. They can be used for surface grinding, cutting and other operations on workpieces.

[0003] Utility model patent CN213164921U discloses a thin resin grinding wheel. This thin resin grinding wheel includes a resin grinding wheel body with a plurality of first positioning holes symmetrically distributed around the resin grinding wheel body and spaced apart radially. A grinding wheel has a plurality of second positioning holes, with the first positioning holes coinciding with the second positioning holes to position and fix the grinding wheel to the surface of the resin grinding wheel body. The second positioning holes are positioned corresponding to a group of first positioning holes at the same distance from the center of the resin grinding wheel body. This thin resin grinding wheel solves the problems of low processing efficiency and poor adaptability associated with thin resin grinding wheels.

[0004] This thin resin grinding wheel has an integral or relatively fixed connection structure between the resin grinding wheel body and the grinding wheel. When the outer diameter of the grinding wheel decreases due to wear during use, due to the lack of a design that allows for flexible replacement of worn parts, the entire grinding wheel can only be discarded, resulting in a large amount of incompletely worn abrasive being wasted and causing unnecessary material loss. Utility Model Content

[0005] The purpose of this invention is to provide an environmentally friendly resin grinding wheel to solve the problem in the background art where a large amount of incompletely worn abrasive is wasted when the wheel is discarded after its outer diameter decreases due to wear during use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An environmentally friendly resin grinding wheel includes a resin grinding wheel assembly, the resin grinding wheel assembly including a grinding part located on the outer side and an annular base tightly bonded to the inner ring of the grinding part, the annular base having an annular edge at the inner ring position. The resin grinding wheel assembly is clamped on the grinding machine spindle by a clamping assembly. The clamping assembly includes an inner clamping plate attached to the rear end of the ring edge and an outer clamping plate attached to the front end of the ring edge. Both the inner clamping plate and the outer clamping plate are circular plate structures. The grinding part, the ring edge, the inner clamping plate and the outer clamping plate are coaxial. A threaded post is coaxially fixed on the grinding machine spindle. The threaded post passes through the inner clamping plate, the ring edge, and the outer clamping plate from back to front, and is then threadedly connected to a locking plate.

[0007] Preferably, the grinding part has a ring structure, the grinding part is made of white corundum particles mixed with resin binder and bonded together, and the clamping assembly is made of metal material; In this setup, the annular grinding section reduces the amount of abrasive filling, while the metal clamping components provide sufficient clamping strength.

[0008] Preferably, the ring base is made entirely of nylon material, and a plurality of outwardly protruding convex plates are provided at equal intervals on the outer circumferential surface of the ring base, the convex plates being embedded in the inner ring surface of the grinding part; In this design, the nylon ring base is both lightweight and wear-resistant, and the protrusion embedded in the grinding section enhances the stability of the connection between the two.

[0009] Preferably, the front end face of the inner clamping plate is provided with a protruding positioning boss, the positioning boss extends into the inner ring of the ring edge, and the height of the positioning boss is less than the thickness of the ring edge; In this configuration, the positioning boss extends into the inner ring of the ring to achieve axial positioning, and the height difference design avoids assembly interference.

[0010] Preferably, the rear end face of the ring base is provided with a plurality of first positioning grooves in an annular shape at equal intervals, and the outer peripheral edge of the front end face of the inner clamping plate is provided with a plurality of protruding first ridges in an annular shape at equal intervals. The size of the first ridges is adapted to the size of the first positioning grooves and their positions correspond one-to-one. In this configuration, the first protruding ridge and the first positioning groove cooperate to achieve circumferential positioning, preventing the inner clamping plate from rotating relative to the ring base.

[0011] Preferably, the front end face of the ring edge is provided with a plurality of second positioning grooves in an annular shape at equal intervals, and the outer peripheral edge of the rear end face of the outer clamping plate is provided with a plurality of protruding second ridges in an annular shape at equal intervals. The size of the second ridges is adapted to the size of the second positioning grooves and their positions correspond one-to-one. In this configuration, the second protruding ridge, in conjunction with the second positioning groove, enhances the connection reliability between the outer clamping plate and the ring edge, thereby improving clamping stability.

[0012] Preferably, a sleeve hole is provided at the axial position of the inner clamping plate, and the threaded post passes through the sleeve hole; In this configuration, the bushing provides a passage for the threaded post, ensuring that the inner clamping plate is coaxially assembled with the grinding machine spindle.

[0013] Preferably, a through hole is provided at the axial position of the outer clamping plate, and the threaded column extends out of the through hole after passing through the sleeve hole. By tightening the locking plate, the locking plate can be pressed backward against the clamping assembly, so that the resin grinding wheel assembly is fixed to the front end of the grinding machine spindle. In this setup, the engagement of the threaded post and the locking plate creates a clamping force, fixing the resin grinding wheel assembly to the front end of the grinding machine spindle.

[0014] Compared with the prior art, the beneficial effects of this utility model are: This environmentally friendly resin grinding wheel reduces the amount of abrasive filling by setting an annular grinding section. When the outer diameter of the grinding section decreases due to wear, the resin grinding wheel assembly can be replaced directly without discarding the entire grinding wheel. This reduces the amount of abrasive wasted due to grinding wheel wear, improves material utilization, lowers operating costs, and is more environmentally friendly. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-5 An environmentally friendly resin grinding wheel includes a resin grinding wheel assembly 100. The resin grinding wheel assembly 100 includes a grinding section 110 located on the outer side and an annular base 120 tightly bonded to the inner ring of the grinding section 110. The grinding section 110 has an annular structure and is made of white corundum particles mixed with resin binder. The annular shape of the grinding section 110 reduces the amount of abrasive filling inside during production. When the outer diameter of the grinding section 110 decreases due to wear and is discarded, the less abrasive filling inside results in less abrasive in the discarded grinding section 110, avoiding waste and being more environmentally friendly.

[0018] like Figure 1 , Figure 2 and Figure 4 As shown, in this utility model, an inner ring edge 121 is provided at the inner ring position of the ring base 120. The resin grinding wheel assembly 100 is clamped on the grinding machine spindle 300 by the clamping assembly 200. The clamping assembly 200 is made of metal material and includes an inner clamping plate 210 attached to the rear end position of the ring edge 121 and an outer clamping plate 220 attached to the front end position of the ring edge 121. Both the inner clamping plate 210 and the outer clamping plate 220 have a circular plate structure. The grinding part 110, the ring edge 121, the inner clamping plate 210 and the outer clamping plate 220 are coaxial. By attaching the ring edge 121 to the inner clamping plate 210 and the outer clamping plate 220, the resin grinding wheel assembly 100 can be stably clamped.

[0019] like Figure 2 and Figure 3 As shown, specifically, the ring base 120 is made entirely of nylon material. The nylon ring base 120 combines lightweight and wear resistance. Several outwardly protruding convex plates 122 are provided at equal intervals on the outer circumferential surface of the ring base 120. The convex plates 122 are embedded in the inner ring surface of the grinding part 110. The convex plates 122 can enhance the connection strength between the ring base 120 and the grinding part 110 and prevent the two from separating.

[0020] like Figure 1 , Figure 4 and Figure 5As shown, furthermore, a threaded post 310 is coaxially fixed on the grinding machine spindle 300. The threaded post 310 passes through the inner clamping plate 210, the ring edge 121, and the outer clamping plate 220 sequentially from back to front, and is then threadedly connected to a locking plate 320. A sleeve hole 212 is provided at the axial position of the inner clamping plate 210, through which the threaded post 310 passes. A through hole 221 is provided at the axial position of the outer clamping plate 220, through which the threaded post 310 passes through the sleeve hole 212 and extends out of the through hole 221. By tightening the locking plate 320, the locking plate 320 can be pushed backward against the clamping assembly 200, thereby fixing the resin grinding wheel assembly 100 to the front end of the grinding machine spindle 300. This structure enables a detachable connection between the resin grinding wheel assembly 100 and the grinding machine spindle 300, facilitating installation and replacement.

[0021] like Figure 4 As shown, in addition, a protruding positioning boss 211 is provided on the front end face of the inner clamping plate 210. The positioning boss 211 extends into the inner ring of the ring edge 121. The height of the positioning boss 211 is less than the thickness of the ring edge 121. The positioning boss 211 can position the ring edge 121 to ensure the coaxiality of the resin grinding wheel assembly 100 during installation.

[0022] like Figures 2-5 As shown, it is worth noting that the rear end face of the ring base 120 is provided with a plurality of first positioning grooves 123 in an annular shape at equal intervals, and the outer periphery of the front end face of the inner clamping plate 210 is provided with a plurality of protruding first ridges 213 in an annular shape at equal intervals. The size of the first ridges 213 and the size of the first positioning grooves 123 are matched and their positions correspond one-to-one. The cooperation between the first ridges 213 and the first positioning grooves 123 can further enhance the connection stability between the inner clamping plate 210 and the ring base 120, and prevent relative rotation between the resin grinding wheel assembly 100 and the inner clamping plate 210 when rotating. The front end face of the ring edge 121 is provided with a plurality of second positioning grooves 124 in an annular shape at equal intervals. The outer peripheral edge of the rear end face of the outer clamping plate 220 is provided with a plurality of protruding second ridges 222 in an annular shape at equal intervals. The size of the second ridges 222 and the size of the second positioning grooves 124 are matched and their positions correspond one-to-one. The cooperation between the second ridges 222 and the second positioning grooves 124 can further enhance the connection stability between the outer clamping plate 220 and the ring edge 121, so that the resin grinding wheel assembly 100 forms a stable structure when it is clamped by the clamping assembly 200, and suppresses the circumferential slippage and radial movement between the resin grinding wheel assembly 100 and the clamping assembly 200.

[0023] In this embodiment, the environmentally friendly resin grinding wheel is used as follows: First, the positioning boss 211 of the inner clamping plate 210 is inserted into the inner ring of the ring edge 121, so that the first protruding ridge 213 corresponds to the first positioning groove 123. Then, the second protruding ridge 222 of the outer clamping plate 220 corresponds to the second positioning groove 124 of the ring edge 121. Next, the threaded post 310 is passed through the sleeve hole 212 of the inner clamping plate 210, the ring edge 121, and the through hole 221 of the outer clamping plate 220 in sequence. Finally, the locking plate 320 is tightened, so that the locking plate 320 presses the clamping assembly 200 backward, and the resin grinding wheel assembly 100 is fixed to the front end of the grinding machine spindle 300. At this time, starting the grinding machine spindle 300 can drive the grinding part 110 to rotate and perform grinding operations.
