Description

Technical Field

[0001] This utility model relates to the field of grinding wheel application technology, and in particular to a concave finned high-efficiency heat dissipation grinding wheel. Background Technology

[0002] In machining processes, grinding wheels are commonly used grinding tools and are widely used in the processing of materials such as metals and ceramics.

[0003] However, during the grinding process, the friction between the grinding wheel and the workpiece generates a lot of heat. If this heat cannot be dissipated in time, it will cause the grinding wheel temperature to rise sharply, which will lead to thermal deformation of the grinding wheel, affecting grinding accuracy and surface quality. At the same time, it will also accelerate the wear of the grinding wheel and reduce its service life.

[0004] Existing grinding wheel heat dissipation structures typically employ simple heat dissipation grooves or holes, which have limited heat dissipation effects and cannot meet the heat dissipation requirements of high-speed and high-precision grinding. Therefore, this invention proposes a concave finned high-efficiency heat dissipation grinding wheel. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a concave finned high-efficiency heat dissipation grinding wheel. Through the unique concave fin structure design, the heat dissipation efficiency of the grinding wheel is significantly improved, the temperature of the grinding wheel during the grinding process is reduced, and the grinding accuracy and service life of the grinding wheel are guaranteed.

[0006] To solve the above technical problems, the present invention adopts a technical solution as follows: a concave fin type high-efficiency heat dissipation grinding wheel is provided, including a base layer and an abrasive layer. The abrasive layer has a plurality of heat dissipation grooves evenly and equidistantly opened on the circumferential arc surface, and the inner walls of the plurality of heat dissipation grooves are all semi-circular. Concave fins are symmetrically fixedly connected to the inner walls of the plurality of heat dissipation grooves near the center.

[0007] Multiple heat dissipation holes are evenly provided on both sides of the abrasive layer near the edge, and the inner walls of the multiple heat dissipation holes are fixedly connected with spiral fins. At the same time, multiple heat dissipation grooves are connected to the corresponding heat dissipation holes through the connecting grooves at both ends.

[0008] The present invention is further configured such that: a central mounting hole is provided at the center of the substrate layer, and both ends of the central mounting hole are extended with convex rings, and the convex rings are arranged in a trapezoidal shape.

[0009] The above technical solution utilizes an extended convex ring to enable the substrate layer to be more stably mounted on the external output shaft, and increases the stability and strength of the connection between the central mounting hole and the output shaft.

[0010] The present invention is further configured such that the outer wall of the substrate layer and the inner wall of the abrasive layer are fixedly connected by a connecting groove and a connecting protrusion, and are integrally formed.

[0011] The above technical solution facilitates the use of connecting grooves to fix the connecting protrusions on the abrasive layer when it is installed on the substrate layer, thereby ensuring stable fixation between the substrate layer and the abrasive layer and preventing damage.

[0012] The present invention is further configured such that: the circumferential arc surface of the abrasive layer is uniformly provided with multiple air channels, and the multiple air channels are equidistantly distributed along the axial direction of the abrasive layer.

[0013] The above technical solution utilizes multiple air ducts to dissipate the high temperature generated inside the grinding wheel during its high-speed rotation, preventing the high temperature generated by the grinding wheel from remaining on its surface.

[0014] The present invention is further configured such that the plurality of concave fins are arranged in a crescent shape and are distributed alternately with the plurality of air ducts.

[0015] The above technical solution facilitates the heat dissipation of high temperature by utilizing the concave fins inside the heat sink, and the dissipated heat is carried away by the airflow inside the air duct, thereby achieving the cooling effect of the heat sink.

[0016] The present invention is further configured such that the inner bottom of the plurality of air ducts is tangential to and connected to the inner bottom of the plurality of heat dissipation slots.

[0017] The above technical solution facilitates the rapid release of high temperatures generated inside the heat dissipation groove during high-speed rotation through the connection of the air duct, thereby improving the heat dissipation efficiency of the grinding wheel.

[0018] The present invention is further configured such that the helical surface of the helical fin is arc-shaped.

[0019] The above technical solution facilitates the use of an arc-shaped design, allowing the incoming air to flow smoothly and increasing the heat dissipation area of ​​the abrasive layer.

[0020] The beneficial effects of this utility model are as follows:

[0021] The present invention proposes a concave finned high-efficiency heat dissipation grinding wheel. By setting heat dissipation grooves with concave fins on the circumferential arc surface and both sides, the heat dissipation area of ​​the grinding wheel is greatly increased, and the heat dissipation efficiency is significantly improved.

[0028] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0029] like Figures 1-4 As shown, a concave finned high-efficiency heat dissipation grinding wheel includes a base layer 1 and an abrasive layer 2. A central mounting hole 11 is provided at the center of the base layer 1, and both ends of the central mounting hole 11 have extended convex rings. The convex rings are trapezoidal in shape. The extended convex rings enable the base layer 1 to be more stably mounted on the external output shaft, and increase the stability and strength of the connection between the central mounting hole 11 and the output shaft. The outer wall of the base layer 1 and the inner wall of the abrasive layer 2 are fixedly connected by a connecting groove 12 and a connecting protrusion 21, and are integrally set. When the abrasive layer 2 is mounted on the base layer 1, the connecting groove 12 can be used to fix the connecting protrusion 21 on the abrasive layer 2, thereby making the base layer 1 and the abrasive layer 2 stably fixed and preventing damage.

[0030] like Figure 5As shown, the abrasive layer 2 has a plurality of heat dissipation grooves 22 evenly spaced on its circumferential arc surface. The inner walls of the plurality of heat dissipation grooves 22 are all semi-circular. Concave fins 221 are symmetrically fixedly connected to the inner walls of the plurality of heat dissipation grooves 22 near the center. The plurality of concave fins 221 are all crescent-shaped and are distributed alternately with the plurality of air ducts 25. This facilitates the heat dissipation grooves 22 to dissipate high temperature by using the concave fins 221 inside, and to carry away the dissipated heat by using the air flow inside the air ducts 25, thereby achieving the cooling effect of the heat dissipation grooves 22.

[0031] Multiple heat dissipation holes 23 are evenly provided on both sides of the abrasive layer 2 near the edge, and the inner walls of the multiple heat dissipation holes 23 are fixedly connected with spiral fins 231. At the same time, multiple heat dissipation grooves 22 are connected to the corresponding heat dissipation holes 23 through the connecting grooves 24 at both ends. The spiral surface of the spiral fins 231 is set in an arc shape, which makes it easy to use the arc shape to allow the incoming air to flow smoothly and increase the heat dissipation area of ​​the abrasive layer 2.

[0032] Multiple air ducts 25 are evenly distributed on the circumferential arc surface of the abrasive layer 2, and the multiple air ducts 25 are equidistantly distributed along the axial direction of the abrasive layer 2. The multiple air ducts 25 can throw out the high temperature generated inside the grinding wheel during high-speed rotation, and prevent the high temperature generated by the grinding wheel from remaining on the surface of the grinding wheel. The inner bottom of the multiple air ducts 25 is tangential to the inner bottom of the multiple heat dissipation grooves 22 and is connected to them, so that the high temperature generated inside the heat dissipation grooves 22 can be quickly released through the connection of the air ducts 25 during high-speed rotation, thereby improving the heat dissipation efficiency of the grinding wheel.

[0033] In use, as the grinding wheel rotates at high speed, air forms an airflow around the grinding wheel. The heat dissipation grooves 22 on the circumferential arc surface are in full contact with the air. The concave fins 221 increase the contact area between the heat dissipation grooves 22 and the air, while changing the airflow path, allowing the air to more effectively remove the heat from the heat dissipation grooves 22. The concave design of the concave fins 221 causes the air to form vortices when flowing through the fins, further enhancing the heat exchange between the air and the fins. The heat dissipation holes 23 on both sides and the spiral fins 231 therein can also interact with the airflow in the lateral direction when the grinding wheel rotates, dissipating the heat inside the grinding wheel. This multi-directional synergy improves the heat dissipation efficiency of the grinding wheel and reduces its temperature.

[0034] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
