Description

Technical Field

[0001] This utility model belongs to the field of grinding wheel technology, and more specifically, it relates to a chip removal 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] When grinding with a grinding wheel, debris is generated between the grinding surface and the surface of the product being ground. This debris can seriously affect the quality and efficiency of grinding. Current technical solutions mostly use centrifugal force during rotation to remove it.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings to provide a chip removal grinding wheel, in order to achieve a more practical purpose. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a chip-removing grinding wheel, which solves the problem that when the grinding wheel is used for grinding, chips are generated between the grinding surface and the surface of the product being ground, and these chips will seriously affect the grinding quality and grinding efficiency.

[0006] The purpose and effect of this chip-removing grinding wheel are achieved by the following specific technical means:

[0007] A chip removal grinding wheel, comprising:

[0008] The grinding wheel body and the mounting hole provided in the middle of the grinding wheel body, the mounting hole is provided with a rotating sealing member, and the rotating sealing member forms a ventilation space above the mounting hole;

[0009] At least one air hole is provided on the outer periphery of the mounting hole. The air hole is connected to the ventilation space, which is also connected to the air outlet of the air pump. When the grinding wheel body rotates, the air pump can pump gas into the ventilation space.

[0010] The bottom surface of the grinding wheel body is provided with at least one chip removal groove that communicates with the air hole, and the chip removal groove extends to the outer peripheral surface of the grinding wheel body.

[0011] Furthermore, the rotating sealing component includes a sealing ring fixedly connected to the upper outer edge of the mounting hole, and a gas collection hood is rotatably connected to the outer circumference of the sealing ring.

[0012] Furthermore, the gas collection hood is fixedly connected to a bracket.

[0013] Furthermore, the bottom of the mounting hole is provided with an air collection groove that communicates with the lower end of the air hole.

[0014] Furthermore, the exhaust end of the air pump is connected to an air pipe, and the other end of the air pipe is fixedly connected to the air collection hood and communicates with the ventilation space.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This invention provides a chip removal groove 12 on the grinding surface of the grinding wheel body 1 and connects the chip removal groove 12 to an air pump 3. During grinding, the air pump 3 pumps air into the chip removal groove 12, and the grinding chips are blown out of the chip removal groove 12 by the gas, which reduces the impact of grinding chips on grinding and thus improves grinding quality and grinding efficiency.
