Description

Technical Field

[0001] This utility model belongs to the field of grinding wheel technology, and more specifically, it relates to a grinding wheel. Background Technology

[0002] Grinding wheels, also known as bonded abrasives, are abrasive tools in which ordinary abrasive grains are bonded together with a bonding agent to form a specific shape (mostly circular with a central through-hole) and possess a certain strength. They generally consist of abrasive grains, a bonding agent, and pores; these three parts are often referred to as the three essential elements of bonded abrasives. According to different bonding agents, common types include ceramic (bonded) grinding wheels, resin (bonded) grinding wheels, and rubber (bonded) grinding wheels. Grinding wheels are the most widely used and extensive type of abrasive tool. They rotate at high speeds and can perform rough grinding, semi-finishing, and finish grinding, as well as grooving and cutting, on the outer and inner diameters, planes, and various profiles of metal or non-metal workpieces.

[0003] For example, invention application number 201310146020.5 discloses an internally cooled grinding wheel, including a disc body and a shaft. The disc body has an inner ring flow channel and several unidirectional curved flow channels starting from the inner ring flow channel and ending at the outer circular surface of the disc body. The unidirectional curved flow channels form coolant nozzles on the outer circular surface of the disc body. The grinding wheel of this invention has a good cooling effect during grinding, avoids damage to the workpiece surface, and improves the processing quality.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, it was discovered that although existing grinding wheels can achieve a better cooling effect, they require the introduction of coolant to achieve the desired cooling effect.

[0005] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings to provide a grinding wheel with greater practical value. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model provides a grinding wheel that solves the problem that while existing grinding wheels can achieve a better cooling effect, they require the introduction of coolant to achieve the desired cooling effect.

[0007] The purpose and function of this utility model of a grinding wheel are achieved by the following specific technical means:

[0008] A grinding wheel, comprising:

[0009] The grinding wheel body and the heat spreader plate are fixedly connected to the bottom of the grinding wheel body. The grinding wheel body has a through hole in the middle and multiple air ducts are arranged radially on the grinding wheel body. The air ducts are fixedly connected to the heat spreader plate. Both the heat spreader plate and the air ducts are made of metal.

[0010] Furthermore, the inner end of the air duct is provided with an opening, which faces the rotation direction of the grinding wheel body.

[0011] Furthermore, multiple arc-shaped heat sinks are fixedly connected to the heat spreader.

[0012] Furthermore, the heat spreader, air duct, and heat sink are all made of copper.

[0013] Furthermore, a mounting base is fixedly connected to the through hole.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This invention uses multiple air ducts 13 arranged radially on the grinding wheel body to introduce gas from the inside to the outside. The gas flows through the air ducts 13 and exchanges heat with the air ducts 13, thereby removing the heat generated by the grinding wheel body 11 during grinding, thus eliminating the need for additional cooling media such as coolant.

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0021] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

[0023] Example:

[0024] As attached Figure 1 To be continued Figure 2 As shown:

[0025] This utility model provides a grinding wheel, comprising:

[0026] The grinding wheel body 11 and the heat spreader 12 are fixedly connected to the bottom of the grinding wheel body 11. The grinding wheel body 11 has a through hole 110 in the middle. Multiple air ducts 13 are arranged in the radial direction of the grinding wheel body 11. The air ducts 13 are fixedly connected to the heat spreader 12. Both the heat spreader 12 and the air ducts 13 are made of metal.

[0027] In this embodiment, multiple air ducts 13 are arranged in the radial direction of the grinding wheel body to introduce gas from the inside to the outside. The gas flows through the air ducts 13 and exchanges heat with the air ducts 13, thereby removing the heat generated by the grinding wheel body 11 during grinding. This eliminates the need for additional cooling media such as coolant, greatly reducing the cooling cost of the grinding wheel body 11.

[0028] An opening 130 is provided at the inner end of the air duct 13, with the opening 130 facing the rotation direction of the grinding wheel body 11. The direction of the opening 130 facing the rotation direction of the grinding wheel body 11 makes it easier for airflow to enter the air duct 13 from the opening 130, increasing the incoming flow area and thus increasing the air intake volume.

[0029] Multiple arc-shaped heat sinks 15 are also fixedly connected to the heat spreader 12. The heat sinks 15 increase the contact area between the heat spreader 12 and the air, further improving the heat dissipation effect.

[0030] The heat spreader 12, air duct 13, and heat sink 15 are all made of copper. Copper has a high thermal conductivity, which allows it to dissipate heat into the air more quickly.

[0031] A mounting base 14 is fixedly connected to the through hole 110. The mounting base 14 facilitates the installation of the grinding wheel body 11 on the grinding equipment.

[0032] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
