Description

Technical Field

[0001] This utility model relates to the field of grinding wheel technology, specifically a combined 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] However, existing combined grinding wheels generate a lot of heat during use, which can easily damage the grinding wheel, reduce its service life, and increase its operating costs.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the above-mentioned technical defects and provide a combined grinding wheel.

[0006] To solve the above problems, the technical solution of this utility model is: a combined grinding wheel, including a grinding wheel abrasive layer, wherein a through hole is provided at the center of the grinding wheel abrasive layer;

[0007] A limiting groove one is evenly distributed on both sides of the abrasive layer of the grinding wheel and is connected to the through hole;

[0008] The substrate comprises two substrates, which are respectively inserted into both sides of the through hole;

[0009] The pressure plate is fixedly connected to the two substrates on opposite sides. Limiting blocks are evenly distributed on the side of the two pressure plates near the abrasive layer of the grinding wheel. The limiting blocks are engaged in the limiting grooves. The two pressure plates are connected to the abrasive layer of the grinding wheel by bolts.

[0010] A heat sink is evenly distributed on the side of the two pressure plates away from the abrasive layer of the grinding wheel.

[0011] Furthermore, a limiting groove is formed on one side of the two substrates, and a limiting block is fixedly connected to the other side of the substrate. The limiting block extends into the limiting groove.

[0012] Furthermore, the pressure plate is made of a thermally conductive material.

[0013] Furthermore, the pressure plate is bonded to both sides of the abrasive layer of the grinding wheel.

[0014] The advantages of this invention compared to existing technologies are as follows: during the grinding process of the abrasive layer of the grinding wheel, a certain amount of heat is generated. By using a pressure plate and a heat sink in combination, the generated heat can be further transferred to the outside, thereby extending the service life of the abrasive layer of the grinding wheel.

[0020] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.

[0021] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0022] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0023] like Figures 1 to 4As shown, a combined grinding wheel includes an abrasive layer 1, a limiting groove 3, a base 4, a pressure plate 5, and a heat dissipation plate 7. A through hole 2 is formed at the center of the abrasive layer 1. The limiting groove 3 is evenly distributed on both sides of the abrasive layer 1 and communicates with the through hole 2. Two bases 4 are provided, each inserted through both sides of the through hole 2. The pressure plate 5 is fixedly connected to the side of the two bases 4 furthest apart. Limiting blocks 6 are evenly distributed on the side of the two pressure plates 5 closest to the abrasive layer 1. The limiting blocks 6 engage with the limiting groove 3. The base 4 is installed through the through hole 2, and the limiting groove 3 and the limiting blocks 6 work together to limit the position of the base 4, preventing gaps or speed differences between the base 4 and the abrasive layer 1 during grinding, thus making the rotation of the abrasive layer 1 more stable. The two pressure plates are connected to the abrasive layer by bolts, so the grinding wheel can be easily disassembled. After the entire assembly is disassembled from the mounting body, the two bases can be pulled out from both sides by removing the bolt structure, allowing for the replacement or removal of the abrasive wheel layer 1. The heat dissipation plate 7 is evenly distributed on the side of the two pressure plates 5 away from the abrasive wheel layer 1. The pressure plates 5 are made of thermally conductive material and are in close contact with both sides of the abrasive wheel layer 1. During the grinding process of the abrasive wheel layer 1, a certain amount of heat is generated. By using the pressure plates 5 and the heat dissipation plate 7 together, the generated heat can be further transferred to the outside, thereby extending the service life of the abrasive wheel layer 1. One of the two bases 4 has a limiting groove 2 8, and the other base 4 is fixedly connected to a limiting block 2 9. The limiting block 2 9 extends into the limiting groove 2 8. By using the limiting groove 2 8 and the limiting block 2 9 together, the stability between the base 4 and the abrasive wheel layer 1 can be further ensured. The center of the two bases 4 has a shaft hole for installing the drive component.
