Description

Technical Field

[0001] This utility model relates to the field of resin grinding wheel technology, specifically a double-sided concave resin grinding wheel that facilitates heat dissipation. Background Technology

[0002] In the field of machining, double-sided grooved resin grinding wheels are widely used in external cylindrical grinding, cutting and other machining processes due to their good toughness and adaptability.

[0003] However, during long-term, high-load grinding operations, the friction between the grinding wheel and the workpiece generates a large amount of heat, which accelerates the wear of the grinding wheel and reduces its service life. Traditional heat dissipation methods mainly rely on increasing the heat dissipation holes on the surface of the grinding wheel or optimizing the thermal conductivity of the grinding wheel material. However, these methods have certain limitations and the heat dissipation effect is not good.

[0004] Therefore, it is necessary to invent a double-sided concave resin grinding wheel that facilitates heat dissipation. Utility Model Content

[0005] The purpose of this invention is to provide a double-sided concave resin grinding wheel that facilitates heat dissipation, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a double-sided concave resin grinding wheel that facilitates heat dissipation, comprising a first ring, a second ring fixedly disposed on the outer wall of the first ring, a grinding wheel body fixedly disposed on the outer wall of the second ring, an annular groove II being formed inside the second ring, a plurality of circular grooves being formed on the outer wall of the second ring, and annular plates being detachably disposed on both sides of the second ring, with an array of heat dissipation fins fixedly disposed on the outer wall of the annular plates.

[0007] Preferably, both sides of the second ring are provided with annular grooves, and the annular plate is movably engaged in the annular grooves.

[0008] Preferably, both sides of the second ring are threaded with symmetrically distributed screws, which movably pass through the annular groove and are inserted into the annular plate.

[0009] Preferably, the annular plate has circular holes on both sides, and the screw moves through the circular holes.

[0010] Preferably, one side of the ring has multiple mounting holes.

[0011] Preferably, the grinding wheel body has arrayed grooves on both sides.

[0012] Preferably, both sides of the second ring are provided with symmetrically distributed threaded holes, and the screw is threadedly inserted into the threaded holes.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. During the operation of the double-sided grooved resin grinding wheel, the grooves on both sides of the grinding wheel body increase the contact area with air, which can initially accelerate air convection and carry away some heat. Another part of the heat generated by the grinding wheel body during operation enters the second annular ring through heat conduction. As the grinding wheel begins to rotate at high speed, the heat dissipation fins rotate accordingly. On the one hand, this accelerates the discharge of hot air from the second annular groove, and on the other hand, it also quickly transfers the heat generated by the grinding wheel body to the surrounding environment, expanding the heat dissipation area and optimizing the heat exchange efficiency, so that the heat is evenly distributed and effectively reducing the overall temperature of the grinding wheel.

[0015] 2. The annular plate is movably engaged with the annular grooves on both sides of the circular ring, and then screws are inserted into the annular plate to achieve a stable installation, which facilitates the replacement or maintenance of the heat dissipation fins and improves the ease of maintenance of the grinding wheel.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only another part of the embodiments of the present utility model, and not all of the 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.

[0023] Example: Figures 1-5As shown, this utility model provides a double-sided concave resin grinding wheel that facilitates heat dissipation, including a first ring 1, a second ring 12 fixedly provided on the outer wall of the first ring 1, a grinding wheel body 13 fixedly provided on the outer wall of the second ring 12, an annular groove 128 opened in the second ring 12, a plurality of circular grooves 122 opened on the outer wall of the second ring 12, and annular plates 18 detachably provided on both sides of the second ring 12, with an array of heat dissipation fins 181 fixedly provided on the outer wall of the annular plates 18.

[0024] Furthermore, annular grooves 124 are provided on both sides of the second annulus 12, and the annular plate 18 is movably engaged in the annular grooves 124.

[0025] Furthermore, both sides of the second annular ring 12 are threaded with symmetrically distributed screws 125, which movably pass through the first annular groove 124 and are inserted into the annular plate 18.

[0026] Furthermore, the annular plate 18 has round holes 183 on both sides, and the screw 125 moves through the round holes 183.

[0027] Furthermore, a plurality of mounting holes 11 are provided on one side of the ring 1.

[0028] Furthermore, the grinding wheel body 13 has arrayed grooves 131 on both sides.

[0029] Furthermore, both sides of the second annulus 12 are provided with symmetrically distributed threaded holes 129, and the screw 125 is threadedly inserted into the threaded holes 129.

[0030] Working principle: When this solution is in use, the multiple mounting holes 11 on one side of the ring 1 are used to fix the grinding wheel on the grinding equipment to ensure that the grinding wheel remains stable during high-speed rotation. During the operation of the double-sided grooved resin grinding wheel, the grooves 131 on both sides of the grinding wheel body 13 increase the contact area with air, which can initially accelerate air convection, carry away some heat, and achieve basic heat dissipation.

[0031] After the grinding operation generates heat, another part of the heat generated by the grinding wheel body 13 during operation enters the second annulus 12 through heat conduction. As the grinding wheel rotates at high speed, the heat dissipation fins 181 rotate accordingly. On the one hand, it accelerates the discharge of hot air in the second annular groove 128 to the outside, and on the other hand, it also quickly transfers the heat generated by the grinding wheel body 13 to the surrounding environment, expanding the heat dissipation area and optimizing the heat exchange efficiency, so that the heat is evenly distributed and effectively reducing the overall temperature of the grinding wheel.

[0032] The annular plate 18 is movably engaged with the annular grooves 124 on both sides of the second annular ring 12, and then screws 125 are inserted into the annular plate 18 to achieve a stable installation, which facilitates the replacement or maintenance of the heat dissipation fins 181 and improves the ease of maintenance of the grinding wheel.
