Description

Technical Field

[0001] This utility model relates to the field of grinding machine technology, specifically a high-strength grinding machine with water cooling. Background Technology

[0002] A grinding wheel machine is a grinding processing equipment with a high-speed rotating grinding wheel as its core working component. It is widely used in machinery manufacturing, metal processing, mold repair and other fields. It mainly consists of a grinding wheel, a motor, a machine base and a protective cover. The grinding wheel can be divided into alumina grinding wheels (suitable for grinding carbon steel, alloy steel, etc.) and silicon carbide grinding wheels (commonly used for grinding cast iron, copper, aluminum and other non-ferrous metals and non-metallic materials) according to different materials. It can achieve processing operations such as grinding, deburring and sharpening tools by high-speed friction between the grinding wheel and the workpiece.

[0003] Currently, during the high-speed grinding process of grinding machines, the intense friction between the grinding wheel and the workpiece generates a large amount of heat. This not only causes problems such as workpiece deformation and annealing due to excessive temperature, affecting machining accuracy and quality, but also accelerates the wear and aging of the grinding wheel, shortening its service life. It may even lead to the safety hazard of grinding wheel breakage due to local overheating. In addition, the motor also generates a large amount of heat when running at high speed, which can easily lead to excessive motor temperature rise. This not only reduces its working efficiency and service life, but may also cause insulation aging, short circuits, or even burnout due to overheating, affecting the normal operation and safety of the equipment. Therefore, we propose a high-strength grinding machine with water cooling. Utility Model Content

[0004] The purpose of this invention is to provide a high-strength grinding wheel machine with water cooling, which facilitates simultaneous water cooling of the motor, grinding wheel, and workpiece. This ensures the stability of the processed workpiece's performance, extends the service life of the grinding wheel and motor, and reduces the risk of equipment failure due to high temperatures. It solves the problem that during high-speed grinding, the intense friction between the grinding wheel and the workpiece generates a large amount of heat, which can cause workpiece deformation and annealing due to excessive temperature, affecting processing accuracy and quality. It also accelerates the wear and aging of the grinding wheel, shortening its service life, and may even lead to the safety hazard of grinding wheel breakage due to localized overheating. Furthermore, the motor also generates a large amount of heat during high-speed operation, easily leading to excessive temperature rise, which not only reduces its working efficiency and service life but may also cause insulation aging, short circuits, or even burnout due to overheating, affecting normal equipment operation and safety.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water-cooled high-strength grinding wheel machine, comprising a base, a grinding wheel, a protective cover, and a rotating motor. The rotor shaft of the rotating motor is hollow inside. One end of the rotor shaft is rotatably connected to a cooling water pipe via a rotary joint. The grinding wheel is fixedly mounted on the outer surface of the rotor shaft, and the grinding wheel and the cooling water pipe are located on opposite sides of the rotating motor. The outer surface of the grinding wheel is provided with a plurality of heat dissipation holes arranged in a ring array at equal intervals, and the heat dissipation holes extend to the inner wall of the grinding wheel. An annular groove is provided on the outer surface of the rotor shaft located inside the grinding wheel. The inner wall of the annular groove is provided with a plurality of water outlet holes arranged in a ring array at equal intervals, and the water outlet holes extend to the inner wall of the rotor shaft.

[0006] Preferably, the protective cover and the rotating motor are fixedly installed on both sides of the upper surface of the base, and the grinding wheel is located inside the protective cover, with an opening on the front surface of the protective cover.

[0007] Preferably, sealing rings are fixedly installed on both sides of the annular groove, and the sealing rings are located inside the grinding wheel.

[0008] Preferably, a fan blade is fixedly installed on the outer surface of the rotor shaft of the rotating motor near the rotary joint.

[0009] Preferably, a number of heat sinks are fixedly installed in a ring array at equal intervals on the outer surface of the rotating motor.

[0010] Preferably, a wind guide shroud is fixedly installed on the outer surface of the rotating motor near the fan blades, and the fan blades are located inside the wind guide shroud.

[0011] Preferably, a bearing housing is fixedly installed on the upper surface of the base between the protective cover and the rotating motor, and a bearing is fixedly installed inside the bearing housing, with the rotor shaft of the rotating motor passing through the bearing.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting up a grinding wheel, heat dissipation holes, a rotating motor, an annular groove, a water outlet, a rotary joint, and a cooling water pipe, achieves simultaneous water cooling of the motor, grinding wheel, and workpiece. This not only ensures the stable performance of the processed parts but also extends the service life of the grinding wheel and motor, while reducing the risk of equipment failure due to high temperatures. The rotating motor drives the grinding wheel to rotate through the rotor shaft, and the grinding wheel performs grinding on the workpiece. Cooling water is delivered to the inside of the rotor shaft through the cooling water pipe. As the cooling water flows inside the rotor shaft, it carries away the heat from the rotating motor. When the cooling water flows inside the heat dissipation holes and sprays out, it also carries away the heat from the grinding wheel and workpiece, thus enabling simultaneous water cooling of the motor, grinding wheel, and workpiece.

[0014] 2. By setting fan blades and heat sinks, this utility model is conducive to the heat dissipation of the rotating motor. The heat of the rotating motor is transferred to the heat sink, and the rotor shaft of the rotating motor drives the fan blades to rotate, which accelerates the airflow near the heat sink, so as to quickly remove the heat from the heat sink and the rotating motor and improve the heat dissipation efficiency.

[0015] 3. By setting up an air guide cover, this utility model can guide the air blown by the fan blades, so that the airflow can better contact the heat sink, improve the heat dissipation efficiency, and at the same time protect the fan blades, effectively preventing damage to the fan blades due to accidental contact, and also avoiding mechanical damage.

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1

[0023] like Figures 1-4As shown, this utility model proposes a high-strength water-cooled grinding wheel machine, including a base 1, a grinding wheel 2, a protective cover 4, and a rotating motor 5. The protective cover 4 and the rotating motor 5 are respectively fixedly installed on both sides of the upper surface of the base 1, with the grinding wheel 2 located inside the protective cover 4. The front surface of the protective cover 4 has an opening 3. The rotor shaft of the rotating motor 5 is hollow inside, and one end of the rotor shaft of the rotating motor 5 is rotatably connected to a cooling water pipe 12 through a rotary joint 11. The cooling water pipe 12 is connected to the rotor shaft of the rotating motor 5 through the rotary joint 11. The grinding wheel 2 is fixedly installed on the outer surface of the rotor shaft of the rotating motor 5, and the grinding wheel 2 and the cooling water pipe 12 are respectively located on both sides of the rotating motor 5. A bearing seat 8 is fixedly installed on the upper surface of the base 1 between the protective cover 4 and the rotating motor 5. A bearing is fixedly installed inside the bearing seat 8, and the rotating motor... The rotor shaft of the machine 5 passes through the bearing. The bearing housing 8 and the bearing support and position the rotor shaft of the rotating motor 5. The outer surface of the grinding wheel 2 is provided with a number of heat dissipation holes 7 arranged in a ring array at equal intervals, and the heat dissipation holes 7 extend to the inner wall of the grinding wheel 2. The outer surface of the rotating motor 5 rotor shaft is provided with an annular groove 13 located inside the grinding wheel 2. The inner wall of the annular groove 13 is provided with a number of water outlet holes 14 arranged in a ring array at equal intervals, and the water outlet holes 14 extend to the inner wall of the rotating motor 5 rotor shaft. The width of the annular groove 13 is less than the thickness of the grinding wheel 2. Sealing rings 15 are fixedly installed on both sides inside the annular groove 13, and the sealing rings 15 are located inside the grinding wheel 2. The cooling water inside the rotating motor 5 rotor shaft enters the annular groove 13 through the water outlet holes 14, and then enters the heat dissipation holes 7.

[0024] In use, the rotating motor 5 drives the grinding wheel 2 to rotate via the rotor shaft. The workpiece is in contact with the grinding wheel 2 at the opening 3, and the grinding wheel 2 performs grinding on the workpiece. Cooling water is delivered to the inside of the rotor shaft through the cooling water pipe 12. As the cooling water flows inside the rotor shaft, it carries away the heat from the rotating motor 5. When the cooling water flows inside the heat dissipation hole 7 and sprays out, it also carries away the heat from the grinding wheel 2 and the workpiece. Thus, the rotating motor 5, the grinding wheel 2, and the workpiece can be cooled down simultaneously by water cooling. This ensures the stable performance of the processed parts, extends the service life of the grinding wheel 2 and the rotating motor 5, and reduces the risk of equipment failure due to high temperature.

The wind guide shroud 6 is open on both sides, the inner diameter of the wind guide shroud 6 is larger than the outer diameter of the rotating motor 5, and the fan blade 10 is located inside the wind guide shroud 6.

[0027] In this embodiment, the heat from the rotating motor 5 is transferred to the heat sink 9. The rotor shaft of the rotating motor 5 drives the fan blades 10 to rotate, and the flowing air is blown towards the heat sink 9 under the guidance of the air guide shroud 6, which accelerates the airflow near the heat sink 9, so as to quickly remove the heat from the heat sink 9 and the rotating motor 5 and improve the heat dissipation efficiency.
