Description

Technical Field

[0001] The utility model relates to the technical field of grinding wheels, in particular to a grinding wheel with a cooling mechanism. Background Art

[0002] Grinding wheel, also known as bonded abrasive tool, is a bonded abrasive tool with a certain strength and ordinary abrasives are bonded into a certain shape by a binder. Grinding wheel is the most important type of abrasive tool in grinding process. It rotates at high speed when used and can perform rough grinding, semi-finishing grinding and fine grinding on metal or non-metal workpieces.

[0003] Some devices on the market generally limit the second pressure plate by setting a rod passing through the middle of the first plug hole. When the connecting tube drives the second pressure plate and the rod to rotate at high speed, the rod will not loosen, thereby improving the limiting and fixing effect of the second pressure plate. The polygonal nut is threadedly connected to the fixing block and one end of the rod, so that the position of the rod at the top of the second pressure plate can be fixed, thereby improving the limiting effect of the second pressure plate. At the same time, the rotational force generated by the high-speed rotation of the connecting tube and the grinding wheel assembly will not affect the fixing effect of the polygonal nut. It is also easy to install and disassemble, thereby improving replacement efficiency.

[0004] However, in actual use of the above equipment, when the grinding wheel is working, the outer surface of the grinding wheel contacts and rubs with the material to generate high temperature, which causes the grinding wheel to overheat and be damaged. In view of this, we propose a grinding wheel with a cooling mechanism. Utility Model Content

[0022] like Figure 1-Figure 3 As shown, the utility model provides a technical solution: a grinding wheel with a cooling mechanism, including a grinding wheel body 1, a rotating shaft 2 is fixedly connected to one side of the grinding wheel body 1, a cooling device is arranged on the outer surface of the grinding wheel body 1, and the cooling device includes a right mounting shell 3, a left mounting shell 4, a water inlet pipe 5, a rotating groove 6, a movable part 7, a limiting part 8, a limiting rod 10, a limiting hole 11 and a guiding part 9.

[0023] In the embodiment of the utility model, a right mounting shell 3 is provided on the outer surface of the rotating shaft 2, and the right mounting shell 3 is also provided with a rotating groove 6, a movable part 7, a limiting part 8, a guiding part 9 and a water inlet pipe 5. A left mounting shell 4 is provided on one side of the right mounting shell 3, and a water inlet pipe 5 is provided on one side of the left mounting shell 4. The water inlet pipe 5 is arranged at an angle, which can make the water sprayed from the water inlet pipe 5 better contact with the outer surface of the grinding wheel body 1. A rotating groove 6 is provided on the side of the left mounting shell 4 close to the grinding wheel body 1, and a movable part 7 is rotatably connected inside the rotating groove 6. One side of the movable part 7 is fixedly connected to the limiting part 8, and the rotating shaft 2 is sleeved inside the limiting part 8. One side of the limiting part 8 fits with the grinding wheel body 1, which can make the limiting part 8 limit the grinding wheel body 1 well. One side of the limiting part 8 is fixedly connected to the limiting rod 10, and the size of the limiting rod 10 The size of the limiting hole 11 is adapted, and the position of the limiting rod 10 corresponds to the position of the limiting hole 11, which can make the limiting rod 10 be well stuck in the limiting hole 11. A limiting hole 11 is provided on one side of the grinding wheel body 1, and a guide member 9 is fixedly connected to the outer surface of the limiting member 8. An inclined surface is provided at the bottom of the guide member 9. A heat dissipation groove 12 is provided on one side of the grinding wheel body 1. The heat dissipation groove 12 is arranged in an arc shape, and the heat dissipation grooves 12 are evenly distributed on both sides of the grinding wheel body 1 in a circular array. In this way, when the grinding wheel body 1 rotates, the arc-shaped heat dissipation grooves 12 arranged on both sides of the grinding wheel body 1 will drive the surrounding wind to rotate with the rotation of the grinding wheel body 1, which enables the grinding wheel body 1 to dissipate heat.

[0024] In the utility model, when in use, the grinding wheel body 1 rotates to grind the material. When the grinding wheel body 1 is overheated, the external water pipe injects water into the water inlet pipe 5, so that the water inside the water inlet pipe 5 contacts the two sides of the grinding wheel body 1 to cool the grinding wheel body 1. At the same time, the limiting rod 10 is embedded in the limiting hole 11, so that when the grinding wheel body 1 rotates, the limiting member 8 rotates and the movable member 7 rotates in the rotating groove 6, which makes the grinding wheel body 1 more stable when rotating. When the water contacts the guide member 9, the water will be hit to the outer surface of the grinding wheel body 1 along the inclined surface set at the bottom of the guide member 9, which makes the grinding wheel body 1 quickly cool down.

[0025] Furthermore, when the grinding wheel body 1 rotates, the arc-shaped heat dissipation grooves 12 arranged on both sides of the grinding wheel body 1 will drive the surrounding wind to rotate along with the rotation of the grinding wheel body 1, so that the grinding wheel body 1 can dissipate heat. At the same time, the water sprayed from the water inlet pipe 5 contacts the inside of the heat dissipation groove 12, which can make the heat dissipation of the grinding wheel body 1 faster.
