Description

Technical Field

[0001] This invention belongs to the field of grinding wheel technology, and more specifically, relates to a water-cooled 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] Cooling with water during grinding is indeed necessary to prevent problems such as annealing, deformation, and wheel breakage caused by overheating of the workpiece. However, improper or non-standard use of water cooling can also bring some potential hazards and adverse effects: improper cooling methods may allow water to enter the electrical components of the electric grinder, causing short circuits or other electrical faults, endangering the safety of operators; continuous water mist and moisture may make the work area slippery, increasing the risk of slipping and falling, and prolonged water accumulation may also cause corrosion to the machinery and equipment.

[0004] Existing technologies mostly use direct water pouring to cool the grinding wheel.

[0005] Based on the search of the aforementioned patents and the findings of existing equipment, the direct water cooling method in the prior art has the aforementioned drawbacks.

[0006] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a water-cooled grinding wheel in order to achieve a more practical purpose. Summary of the Invention

[0007] To address the aforementioned technical problems, this invention provides a water-cooled grinding wheel to solve the problems of electrical short circuits and high humidity in the working environment caused by direct water cooling in the prior art.

[0010] The grinding wheel body has an inner through hole in the middle and multiple cooling channels arranged radially. The inner through hole has an inner channel retaining ring and an outer channel retaining ring installed on the outer periphery of the grinding wheel body. The inner channel retaining ring has a second channel and the outer channel retaining ring has a first channel. The two ends of the cooling channels are respectively connected to the first channel and the second channel. The grinding wheel body is arranged on the outer periphery of the outer channel retaining ring.

[0011] An outer tube and an inner tube, wherein one end of the outer tube is connected to a first flow channel and one end of the inner tube is connected to a second flow channel;

[0013] The inner manifold includes an inner shell with an open end face, an inner cavity, an inner sealing ring between the two side walls of the inner cavity, an inner sealing cover plate rotatably connected to the inner sealing ring, and the other end of the inner tube is connected to the inner manifold.

[0014] Furthermore, the inner sealing cover plate is provided with an inner retaining ring portion, and the outer sealing cover plate is provided with an outer retaining portion. The inner retaining ring portion and the outer retaining portion are respectively disposed in the inner cavity and the outer cavity, and the inner retaining ring portion and the outer retaining portion are respectively engaged with the inner sealing retaining ring and the outer sealing retaining ring.

[0015] Furthermore, the inner flow channel retaining ring includes a second retaining ring body and a second retaining ring locking plate;

[0016] The external flow channel retaining ring includes a first retaining ring body and a first retaining ring locking plate.

[0017] Furthermore, the outer sealing cover is provided with an outer extension plate, and the inner sealing cover is provided with an inner extension plate.

[0018] Furthermore, a heat insulation pad is provided between the inner extension plate and the outer extension plate.

[0019] Furthermore, the material of the heat insulation pad is ceramic.

[0023] Furthermore, the outer flow channel retaining ring and the grinding wheel body are bonded and fixed together with adhesive.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] The technical solution of this invention achieves rapid cooling of the grinding wheel body by setting a rotatable water cooling channel in the grinding wheel body, thereby cooling the grinding wheel body. Since there is no water directly cooling the grinding wheel body, there will be no electrical short circuit. At the same time, it can effectively ensure the normal range of humidity in the working environment and avoid excessive humidity from corroding the parts. Attached Figure Description

[0036] Example:

[0037] As attached Figure 1 To be continued Figure 5 As shown:

[0038] This invention provides a water-cooled grinding wheel, comprising:

[0039] The grinding wheel body 1 has an inner through hole 12 in the middle. The grinding wheel body 1 has multiple cooling channels 11 arranged radially. The inner through hole 12 is provided with an inner channel retaining ring 3 and an outer channel retaining ring 2 installed on the outer periphery of the grinding wheel body 1. The inner channel retaining ring 3 is provided with a second channel 30, and the outer channel retaining ring 2 is provided with a first channel 20. The two ends of the cooling channels 11 are respectively connected to the first channel 20 and the second channel 30. The outer periphery of the outer channel retaining ring 2 is provided with a grinding wheel body 4.

[0040] The outer tube 5 and the inner tube 6 are connected, with one end of the outer tube 5 connected to the first flow channel 20 and one end of the inner tube 6 connected to the second flow channel 30.

[0041] Foreign exchange flow ring 7 includes an outer shell 71 with one end face open, an outer cavity 70 is provided on the outer shell 71, an outer sealing ring 73 is provided between the two side walls of the outer cavity 70, an outer sealing ring 73 is rotatably connected to an outer sealing cover plate 72, and the other end of the outer tube 5 is connected to the foreign exchange flow ring 7.

Since the inner sealing cover 82 is rotated and sealed to the inner shell 81, and the outer sealing cover 72 is rotated and sealed to the outer shell 71, it can be ensured that the cooling water flows in the water-cooling channel when the grinding wheel body 1 is rotating, thereby achieving cooling of the grinding wheel body 1 and the grinding wheel body 4, avoiding coolant leakage, which would lead to equipment short circuit and increased ambient humidity.

[0044] The inner sealing cover plate 82 is provided with an inner retaining ring portion 85, and the outer sealing cover plate 72 is provided with an outer retaining portion 75.

[0052] The material of the heat insulation pad 9 is ceramic.

[0053] The material of the heat insulation pad 9 is aerogel.

[0054] The use of ceramics and aerogels achieves excellent thermal insulation, avoiding heat exchange between the inner extension plate 84 and the outer extension plate 74.

[0055] A heat insulation material, which is ceramic or aerogel, is provided between the external flow ring 7 and the internal flow ring 8.

[0056] The outer tube 5 and the inner tube 6 are made of high-temperature resistant plastic.

[0057] The outer flow channel retaining ring 2 and the grinding wheel body 4 are bonded and fixed together by an adhesive. The adhesive is either phenolic resin or epoxy resin.
