Description

Technical Field

[0001] This utility model belongs to the field of grinding wheel technology, and more specifically, it relates to a friction-type 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] Currently, most grinding wheels are cooled by air. For example, a high-heat-dissipation grinding wheel, as described in application number CN202222876462.2, includes a mounting base. A first grinding wheel body is mounted on the top of the mounting base, and a second grinding wheel body is mounted on the bottom. Heat dissipation holes are fixedly provided inside both the first and second grinding wheel bodies. Heat dissipation rings are fixedly connected inside both the first and second grinding wheel bodies. Support blocks are fixedly connected to the top and bottom of the mounting base, and heat dissipation fins are fixedly connected to the outside of the support blocks. Mounting brackets are fixedly connected to the top and bottom of the mounting base. This high-heat-dissipation grinding wheel uses heat dissipation fins to conduct heat away from the interior of the first and second grinding wheel bodies, achieving rapid heat dissipation. The heat dissipation holes inside the first and second grinding wheel bodies increase airflow and improve heat dissipation. This structure achieves rapid heat dissipation of the grinding wheel, solving the problem of excessively high grinding wheel temperature during grinding.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, although air cooling can solve the heat dissipation problem, the current grinding wheels have low heat dissipation efficiency due to the limitations of their operating principle.

[0005] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a friction-type water-cooled grinding wheel in order to achieve a more practical purpose. Utility Model Content

[0006] To address the aforementioned technical problems, this invention provides a friction-type water-cooled grinding wheel to solve the problem of low heat dissipation efficiency in existing grinding wheels.

[0007] The purpose and effect of this utility model of a friction-type water-cooled grinding wheel are achieved by the following specific technical means:

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This utility model utilizes water as a cooling medium to improve the cooling efficiency of a grinding wheel. Water can quickly absorb heat from the grinding wheel, thus achieving rapid cooling. The grinding wheel and cylinder are in thermally conductive contact; once heat is generated in the grinding wheel, it is conducted to the cylinder and absorbed by the water within the cylinder.

[0029] Example:

[0030] As attached Figure 1 To be continued Figure 4 As shown:

[0031] This utility model provides a friction-type water-cooled grinding wheel, comprising:

[0032] A grinding wheel 11, wherein the grinding wheel 11 is provided with a disc body 112 and a grinding wheel grinding part 111 fixedly connected to the disc body 112;

[0033] The frame 12 has at least one guide sleeve 13 fixedly connected to it. The guide sleeve 13 is slidably connected to a guide shaft 14. A cylinder 15 is fixedly connected to the end of the guide shaft 14. A spring 16 is provided between the cylinder 15 and the frame 12. One end of the spring 16 abuts against the cylinder 15, and the other end of the spring 16 abuts against the frame 12.

[0034] The disc 112 is in thermal contact with the cylinder 15;

[0035] The water injection mechanism is capable of injecting cooling water into the cylinder 15.

[0036] In this embodiment, water is used as the cooling medium to improve the cooling efficiency of the grinding wheel. Water can quickly absorb heat from the disc 112, thus achieving rapid cooling. The disc 112 and cylinder 15 are in thermally conductive contact. Once the disc 112 generates heat, it is conducted to the cylinder 15 and absorbed by the water within the cylinder 15. This thermally conductive contact between the disc 112 and cylinder 15 ensures that heat conduction occurs while the disc 112 and cylinder 15 rotate relative to each other, thereby achieving rapid cooling of the grinding wheel 11.

[0037] The water injection mechanism includes a water pump 21 and a water tank 22. The water pump 21 is connected to the water tank 22. The cylinder 15 is provided with a water outlet 18 and a water inlet 20. The water pump 21 is connected to the water inlet 20.

[0038] When in use, cooling water needs to be filled into the water tank 22. The water pump 21 is connected to the bottom of the water tank 22 to draw water from the water tank 22, while the water pump 21 is connected to the cylinder 15 to draw water into the cylinder 15.

[0039] The outlet 18 is equipped with a solenoid valve 19. When the water in the cylinder 15 reaches a certain temperature, the solenoid valve 19 is opened to discharge the water from the cylinder 15.

[0040] The disc body 112 is made of aluminum alloy. A heat-conducting iron plate 23, made of stainless steel, is fixedly connected to the side of the cylindrical body 15 near the disc body 112. The heat-conducting iron plate 23 is in contact with the disc body 112 and can conduct heat between the two. The elastic force of the spring 16 applies pressure to the cylindrical body 15, making the heat-conducting iron plate 23 adhere tightly to the disc body 112.

[0041] A temperature sensor 17 is fixedly connected to the cylinder 15, and the temperature sensor 17 can detect the temperature of the cylinder 15. The temperature sensor 17 is used to detect the temperature of the cylinder 15. A control circuit board is also provided, which is electrically connected to the temperature sensor 17, the solenoid valve 19, and the water pump 21 to realize the start and stop control of the solenoid valve 19 and the water pump 21, and to receive the temperature data information detected by the temperature sensor 17.

[0042] The frame 12 is provided with at least one mounting ear 121, and the mounting ear 121 is provided with at least one through hole 122. The mounting ear 121 and the through hole 122 thereon facilitate the fixed installation of the frame 12.

[0043] The specific usage and function of this embodiment are as follows:

[0044] In use, the frame 12 is installed on an external fixed support, and the grinding wheel 11 is connected to the motor of the grinding equipment. The heat-conducting iron plate 23 is then in contact with the disc 112. The motor of the grinding equipment drives the grinding wheel 11 to rotate. The heat generated by the rotation of the grinding wheel 11 and grinding is conducted to the cylinder 15 through the heat-conducting iron plate 23 and absorbed by the cooling water in the cylinder 15. When the temperature sensor 17 detects that the temperature is too high, the control circuit board controls the solenoid valve 19 to open and drain the water in the cylinder 15. After the water is drained, the solenoid valve 19 is closed, and the water pump 21 is started to pump the cooling water in the water tank 22 into the cylinder 15, thus continuously cooling the grinding wheel 11.

Many modifications and variations will be apparent to those skilled in the art.
