Description

Technical Field

[0001] This utility model belongs to the field of heat dissipation grinding wheel technology, and in particular relates to a heat dissipation grinding wheel. Background Technology

[0002] Grinding wheels, also known as bonded abrasives, are abrasives made by bonding ordinary abrasives into a certain shape (mostly circular with a central hole) with a bonding agent, and have a certain strength. They are generally composed of abrasives, bonding agent, and pores, which are often referred to as the three elements of bonded abrasives.

[0003] For example, Chinese patent CN220029892U discloses a heat-dissipating grinding wheel, including a grinding wheel body and a hollow part of the grinding wheel body. Both end faces of the grinding wheel body are provided with pressure plates. Pressure tongues are radially arranged on the side of the pressure plates near the grinding wheel body, forming a heat dissipation cavity between adjacent pressure tongues. Heat dissipation holes are formed on the pressure plates, and a bolt is installed between the two pressure plates, passing through the hollow part of the grinding wheel. Threaded holes are formed on the pressure plates corresponding to the bolts, and the bolts are threaded into the threaded holes. A nut is installed at one end of the bolt. This invention transforms the original method of directly pressing the pressure plates onto the grinding wheel into using pressure tongues pressing onto the grinding wheel body. The heat dissipation cavity formed between adjacent pressure tongues allows the heat generated when the grinding wheel body rotates to be dissipated through the heat dissipation cavity between adjacent pressure tongues, resulting in better heat dissipation without affecting the strength and working performance of the grinding wheel.

[0004] The aforementioned patent has the following problems:

[0005] This patent has some drawbacks in its use. For example, the grinding wheel in this device only uses the heat dissipation chamber to cool it, relying solely on the natural cooling of the grinding wheel. This cooling effect is not good, leading to overheating and damage of the grinding wheel even under high-intensity use. Therefore, we propose a heat-dissipating grinding wheel. Utility Model Content

[0006] The purpose of this invention is to provide a heat-dissipating grinding wheel to solve the problems mentioned in the background art.

[0007] In view of this, the present invention provides a heat-dissipating grinding wheel, comprising:

[0008] The mounting shaft has a mounting plate sleeved on it. A grinding wheel is fixedly mounted on the periphery of the mounting plate. A heat-conducting plate is fixedly mounted on the periphery of the mounting plate and inside the grinding wheel. Heat-conducting plates are fixedly mounted on the periphery of the mounting plate and at the top and bottom of the grinding wheel. The mounting plate has several through holes. An arc-shaped plate is fixedly mounted on the top of the mounting plate above each of the several through holes. Several wind baffles are fixedly mounted on the bottom of the mounting plate.

[0009] A fixing component is located on the mounting shaft and is used to fix the mounting piece.

[0010] In this technical solution, during installation, the operator first places the mounting plate onto the mounting shaft and secures it using a fixing assembly. When the grinding wheel is in use, the rotation of the mounting shaft causes the mounting plate to rotate via the fixing assembly, which in turn causes the grinding wheel to rotate. The grinding wheel then becomes usable and generates a significant amount of heat. This heat is transferred to the mounting plate via heat-conducting plate one and two heat-conducting plates two. The rotation of the mounting plate causes several curved plates and several baffle plates to rotate. The plate has an arc-shaped structure, so when the several arc-shaped plates rotate, they will drive air into several through holes, allowing the air to pass through quickly and accelerating the airflow within the through holes. This airflow can carry away the heat from the mounting plate, thus achieving the purpose of heat dissipation for the mounting plate. At the same time, the air blown out by the rotating baffles can dissipate heat from the grinding wheel, and the heat-conducting plate one and the two heat-conducting plates two can continuously carry away the heat generated on the grinding wheel, resulting in good heat dissipation for the grinding wheel and extending its service life.

[0011] In the above technical solution, the fixing component further includes:

[0012] The mounting bracket is fixedly mounted on the mounting shaft and located at the bottom of the mounting plate. The mounting plate has several circular holes. Several threaded rods are fixedly mounted on the top of the mounting bracket. The top ends of the threaded rods pass through the several circular holes and extend to the outside. A second buffer pad that contacts the mounting plate is fixedly mounted on the top of the mounting bracket. A limiting plate is fitted on the threaded rods and above the mounting plate. Nuts are threaded onto the top ends of the threaded rods and at the top of the limiting plate. A first buffer pad that contacts the mounting plate is fixedly mounted on the bottom of the limiting plate.

[0013] In this technical solution, during installation, the operator first places the mounting plate on the mounting shaft and then fits the several round holes on the mounting plate onto several threaded rods until the bottom of the mounting plate rests against the buffer pad. Next, the operator places the limiting disc on the mounting shaft and then onto several threaded rods. At this point, the buffer pad at the bottom of the limiting disc will contact the top of the mounting plate. Then, the operator places several nuts onto the threaded rods and rotates the nuts. Under the action of the threads, the nuts will move downwards and press the limiting disc downwards. The downward movement of the limiting disc, along with the mounting bracket, will press the mounting plate, thus fixing the mounting plate onto the mounting shaft.

[0014] In the above technical solution, further, the top end of the threaded rod is inserted into the round hole, the threaded rods are distributed in a ring at equal intervals, and the round holes are all located between the through holes.

[0015] In this technical solution, it is ensured that the top of the threaded rod can be inserted into the circular hole, thus ensuring the structural stability of the threaded rods and the structural stability of the circular holes.

[0016] In the above technical solution, further, the plurality of the arc-shaped plates are distributed in a ring with equal spacing, and the plurality of the windbreak plates are distributed in a ring with equal spacing.

[0017] In this technical solution, the distribution of several curved plates and several wind deflectors is ensured to be uniform.

[0018] In the above technical solution, furthermore, the two heat-conducting plates are respectively in close contact with the top and bottom of the grinding wheel on opposite sides.

[0019] In this technical solution, it is ensured that the two heat-conducting plates can dissipate the heat from the grinding wheel.

[0020] In the above technical solution, the wind baffle has an arc-shaped structure, and the heat-conducting sheet is fixedly connected to the grinding wheel.

[0021] In this technical solution, it is ensured that the air blown out by the baffle can dissipate heat from the grinding wheel, and that the heat-conducting plate can conduct heat out of the grinding wheel.

[0022] The beneficial effects of this utility model are:

[0023] This heat-dissipating grinding wheel, through the setting of a fixing component, and the cooperation of the fixing component, mounting plate, grinding wheel, heat-conducting plate one, two heat-conducting plates two, several arc-shaped plates, several through holes and several baffle plates, makes the heat dissipation effect of the grinding wheel better, thereby extending the service life of the grinding wheel.

[0036] Please see Figure 1 - Figure 5 As shown, this embodiment provides a heat dissipation grinding wheel, including:

[0037] Mounting shaft 1, mounting plate 2 is sleeved on mounting shaft 1, grinding wheel 3 is fixedly mounted on the periphery of mounting plate 2, heat conduction plate 4 is fixedly mounted on the periphery of mounting plate 2 and inside grinding wheel 3, heat conduction plate 5 is fixedly mounted on the periphery of mounting plate 2 and at the top and bottom of grinding wheel 3, several through holes 6 are opened on mounting plate 2, arc plate 7 is fixedly mounted on the top of mounting plate 2 and above several through holes 6 respectively, and several wind baffles 15 are fixedly mounted on the bottom of mounting plate 2.

[0038] A fixing component is located on the mounting shaft 1 and is used to fix the mounting piece 2.

[0039] During installation, the operator first places the mounting plate 2 onto the mounting shaft 1 and secures it using a fixing assembly. When the grinding wheel 3 is in use, the rotation of the mounting shaft 1 causes the mounting plate 2 to rotate via the fixing assembly, which in turn causes the grinding wheel 3 to rotate. The grinding wheel 3 is then ready for use. During use, the grinding wheel 3 generates a significant amount of heat, which is transferred to the mounting plate 2 via heat-conducting plate 4 and two heat-conducting plates 5. The rotation of the mounting plate 2 causes several curved plates 7 and several baffle plates 15 to rotate. The 7 has an arc-shaped structure, so when the several arc plates 7 rotate, they will drive air into the several through holes 6, allowing the air to pass through the several through holes 6 quickly, which can accelerate the air circulation in the several through holes 6. The air circulation in the several through holes 6 can carry away the heat on the mounting plate 2, thereby achieving the purpose of heat dissipation for the mounting plate 2. At the same time, the air blown out by the several baffle plates 15 can dissipate heat from the grinding wheel 3, and the heat-conducting plate 1 4 and the two heat-conducting plates 2 5 can continuously carry away the heat generated on the grinding wheel 3, making the heat dissipation effect of the grinding wheel 3 better, thereby extending the service life of the grinding wheel 3. Example

[0040] This embodiment provides a heat dissipation grinding wheel, which, in addition to the technical solutions of the above embodiments, also has the following technical features, including a fixing component:

[0041] Mounting bracket 8 is fixedly mounted on mounting shaft 1 and located at the bottom of mounting plate 2. Mounting plate 2 has several round holes 10. Several threaded rods 9 are fixedly mounted on the top of mounting bracket 8. The top ends of the threaded rods 9 pass through the several round holes 10 and extend to the outside. A second buffer pad 14 that contacts the mounting plate 2 is fixedly mounted on the top of mounting bracket 8. The same limiting plate 11 is sleeved on the threaded rods 9 and above the mounting plate 2. Nuts 13 are threadedly installed on the top ends of the threaded rods 9 and on the top of the limiting plate 11. A first buffer pad 12 that contacts the mounting plate 2 is fixedly mounted on the bottom of the limiting plate 11.

[0042] During installation, the operator first places the mounting plate 2 onto the mounting shaft 1, and then places several round holes 10 on the mounting plate 2 onto several threaded rods 9 until the bottom of the mounting plate 2 rests against the buffer pad 14. Then, the operator places the limiting plate 11 onto the mounting shaft 1 and places the limiting plate 11 onto several threaded rods 9. At this time, the buffer pad 12 at the bottom of the limiting plate 11 will contact the top of the mounting plate 2. Then, the operator places several nuts 13 onto several threaded rods 9 and rotates the nuts 13. Under the action of the threads, the nuts 13 will move downward and press the limiting plate 11 downward. The downward movement of the limiting plate 11 will press the mounting plate 2 together with the mounting bracket 8, thus fixing the mounting plate 2 onto the mounting shaft 1. Example

[0043] This embodiment provides a heat dissipation grinding wheel, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the top end of the threaded rod 9 is inserted into the round hole 10, a plurality of threaded rods 9 are distributed in a ring at equal intervals, and a plurality of round holes 10 are all located between a plurality of through holes 6.

[0044] Specifically, it ensures that the top end of the threaded rod 9 can be inserted into the round hole 10, thus ensuring the structural stability of the threaded rods 9 and the round holes 10. Example

[0045] This embodiment provides a heat dissipation grinding wheel, which, in addition to the technical solutions of the above embodiments, also has the following technical features: a plurality of arc-shaped plates 7 are distributed in a ring at equal intervals, and a plurality of wind baffles 15 are distributed in a ring at equal intervals.

[0046] In this process, it is ensured that the distribution of several arc-shaped plates 7 and several windbreak plates 15 is uniform. Example

[0047] This embodiment provides a heat dissipation grinding wheel, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the two heat-conducting plates 5 are respectively in close contact with the top and bottom of the grinding wheel disk 3 on opposite sides.

[0048] Among them, it is ensured that the two heat-conducting plates 25 can dissipate the heat from the grinding wheel 3. Example

[0049] This embodiment provides a heat dissipation grinding wheel, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the baffle plate 15 has an arc-shaped structure, and the heat-conducting plate 4 is fixedly connected to the grinding wheel disk 3.

[0050] Among them, it is ensured that the air blown out by the baffle 15 can dissipate heat from the grinding wheel 3, and that the heat-conducting plate 4 can conduct heat out of the grinding wheel 3.

[0051] Working principle: During installation, the operator first places the mounting plate 2 on the mounting shaft 1 and places several round holes 10 on the mounting plate 2 on several threaded rods 9 until the bottom of the mounting plate 2 abuts against the buffer pad 2 14. Then, the operator places the limiting plate 11 on the mounting shaft 1 and places the limiting plate 11 on several threaded rods 9. At this time, the buffer pad 12 at the bottom of the limiting plate 11 will contact the top of the mounting plate 2. Then, the operator places several nuts 13 on several threaded rods 9 respectively and rotates the nuts 13. Under the action of the threads, the nuts 13 will move downward and squeeze the limiting plate 11 downward. The downward movement of the limiting plate 11 will squeeze the mounting plate 2 together with the mounting bracket 8, which can fix the mounting plate 2 on the mounting shaft 1.

[0052] When the grinding wheel 3 is in use, the rotation of the mounting shaft 1 drives the mounting bracket 8 to rotate. The rotation of the mounting bracket 8 drives the mounting plate 2 to rotate via several threaded rods 9. The rotation of the mounting plate 2 drives the grinding wheel 3 to rotate. At this time, the grinding wheel 3 can be used. The grinding wheel 3 generates a lot of heat during use. The heat generated by the grinding wheel 3 is transferred to the mounting plate 2 through the heat-conducting plate 1 4 and the two heat-conducting plates 2 5. The rotation of the mounting plate 2 drives several arc-shaped plates 7 and several wind baffles 15 to rotate. Because the arc-shaped plates 7 have an arc-shaped structure, several When the arc plate 7 rotates, it draws air into the through holes 6, allowing the air to pass through quickly and accelerating the airflow within the through holes 6. This airflow carries away the heat from the mounting plate 2, thus achieving the purpose of heat dissipation for the mounting plate 2. At the same time, the air blown out by the rotating baffles 15 can dissipate heat from the grinding wheel 3. Furthermore, the heat-conducting plate 1 4 and the two heat-conducting plates 2 5 can continuously carry away the heat generated on the grinding wheel 3, resulting in a better heat dissipation effect for the grinding wheel 3 and extending its service life.
