[0001] The utility model relates to the field of grinding wheels, and particularly relates to a combined grinding wheel structure. Background Art

[0002] A grinding wheel is also called a vitrified abrasive tool. A grinding wheel is a vitrified abrasive tool in which ordinary abrasives are consolidated into a certain shape (mostly circular with a through hole in the center) by a binder and has a certain strength. It generally consists of abrasives, a binder, and pores. These three parts are often called the three elements of a vitrified abrasive tool. According to different classifications of binders, common ones include ceramic (binder) grinding wheels, resin (binder) grinding wheels, and rubber (binder) grinding wheels;

[0003] However, when the grinding wheel is in use, due to its working method, when the grinding wheel rotates at high speed and contacts the cutting tool, it will cause the outer edge of the grinding wheel to overheat. A large amount of heat will accumulate during the use of the grinding wheel, causing the cutting tool to overheat and affecting the performance of the cutting tool. This will not only affect the service life of the grinding wheel but also easily cause burns to people. And the contact position between the grinding wheel and the cutting tool is usually at the outer edge of the grinding wheel, making it difficult to cool the overheated area;

[0004] Therefore, it is very necessary to propose a combined grinding wheel structure to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a combined grinding wheel structure to solve the problems that the overheating at the outer edge of the grinding wheel affects the service life of the grinding wheel and the performance of the cutting tool, and the contact position is usually at the outer edge of the grinding wheel, making it difficult to cool the overheated area.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A combined grinding wheel structure includes two grinding wheel bodies and a connecting shaft for connecting the two grinding wheel bodies. Two side plates are movably arranged on the outer side of the connecting shaft. A plurality of air guide plates are fixedly arranged on the surfaces of the side plates and the grinding wheel bodies corresponding to each other. The air guide plates are used for cooling the outer edge of the grinding wheel body;

[0007] A protective ring is fixedly arranged on the surface of the side plate corresponding to the grinding wheel body. An air guide ring is fixedly arranged inside the protective ring. The cross-section of the air guide ring is triangular.

[0008] Preferably, a plurality of air guide grooves are formed on one surface of the air guide plate. The air guide grooves are arc-shaped. A plurality of air guide grooves on the same air guide plate are arranged in a linear array.

[0009] Preferably, the air guide plate is arc-shaped.

[0011] Preferably, the diameter of the grinding wheel body is larger than the diameter of the protective ring.

[0012] Preferably, a plurality of the air guide plates are located inside the air guide ring.

[0013] Preferably, a plurality of mounting rings are provided on the outer side of the grinding wheel body, and the grinding wheel body and the side plate are mounted on the connecting shaft through the mounting rings.

[0014] Preferably, circular holes for the connecting shaft to pass through are formed through one ends of the grinding wheel body, the side plate, and the mounting ring.

[0015] Technical effects and advantages of the present utility model:

[0016] 1. Through the arrangement of the air guide plates, when an operator uses the grinding wheel body, the rotation of the grinding wheel body and the side plate drives the air guide plates to rotate, so that the air guide plates fan the outer edge of the grinding wheel body to reduce the temperature at the outer edge of the grinding wheel body. When the grinding wheel body is working, the outer edge of the grinding wheel body is automatically cooled at the same time, combining the heat dissipation and the grinding function of the grinding wheel body. When the air guide plates rotate, the air is facilitated to blow in a certain direction through the arrangement of the air guide grooves;

[0017] 2. The protective ring is used to prevent the operator from accidentally touching the air guide plates, and through the arrangement of the air guide ring, the wind blocked by the protective ring is discharged outward from the air guide ring, making the best use of wind energy to the greatest extent;

[0018] 3.

[0026] The present invention provides a combined grinding wheel structure as shown in Figure 1 - Figure 5 which includes two grinding wheel bodies 1 and a connecting shaft 2 for connecting the two grinding wheel bodies 1. The connecting shaft 2 is arranged in a grinding machine, which is not shown in the figure and is prior art, so no more description will be given here. The grinding wheel body 1 is prior art, so no more description will be given here. Two side plates 3 are movably arranged outside the connecting shaft 2. A plurality of mounting rings 8 are arranged outside the grinding wheel body 1. The grinding wheel body 1 and the side plates 3 are mounted on the connecting shaft 2 through the mounting rings 8. The grinding wheel body 1 and the side plates 3 are mainly fixed by the mounting rings 8. The mounting ring 8 is a locking ring and is prior art, so no more description will be given here. Mounting rings 8 are arranged at both ends of the grinding wheel body 1 and the side plates 3. The positions of the grinding wheel body 1 and the side plates 3 are fixed by the two mounting rings 8, or the positions of the grinding wheel body 1 and the side plates 3 can be adjusted according to the usage situation. Circular holes for the connecting shaft 2 to pass through are formed through one end of the grinding wheel body 1, the side plates 3, and the mounting rings 8.

[0027] The operator first sequentially installs the mounting rings 8, side plates 3, mounting rings 8, mounting rings 8, grinding wheel bodies 1, mounting rings 8, mounting rings 8, grinding wheel bodies 1, mounting rings 8, mounting rings 8, side plates 3, and mounting rings 8 on the connecting shaft 2, and then locks the mounting rings 8 to complete the fixation of the grinding wheel bodies 1 and the side plates 3. The connecting shaft 2 is connected to the grinding wheel bodies 1 and the side plates 3 through key grooves and keys, which is convenient for the connecting shaft 2 to drive the grinding wheel bodies 1 and the side plates 3 to rotate. The key grooves and keys are not shown in the figure and are prior art, so no more description will be given here.

[0028] A plurality of air guide plates 4 are fixedly arranged on the surfaces of the side plates 3 and the grinding wheel bodies 1 corresponding to each other. The diameter of the grinding wheel body 1 is larger than the diameter of the protective ring 6. The plurality of air guide plates 4 are located inside the air guide ring 7. The air guide plates 4 are used for cooling the outer edge of the grinding wheel body 1. The air guide plates 4 are arranged in an arc shape. A plurality of air guide grooves 5 are formed on one surface of the air guide plates 4. The air guide grooves 5 are arranged in an arc shape, which is convenient for driving the wind force towards one side. The plurality of air guide grooves 5 on the same air guide plate 4 are arranged in a linear array, and the plurality of air guide plates 4 are arranged in a circular array to ensure the stability of the grinding wheel body 1 when it rotates at a high speed.

[0029] Through the setting of the air deflector 4, when the operator uses the grinding wheel body 1, the rotation of the grinding wheel body 1 and the side plate 3 drives the air deflector 4 to rotate, so that the air deflector 4 blows air to the outer edge of the grinding wheel body 1 to reduce the temperature at the outer edge of the grinding wheel body 1. When the grinding wheel body 1 is working, the temperature at the outer edge of the grinding wheel body 1 is automatically reduced at the same time, combining heat dissipation and the grinding function of the grinding wheel body 1. When the air deflector 4 rotates, the air is guided through the air guide groove 5, which facilitates the blowing direction of the wind;
