Description

Technical Field

[0001] This utility model relates to the field of diamond grinding wheel technology, and in particular to a diamond grinding wheel device with high-efficiency heat dissipation function. Background Technology

[0002] A diamond grinding wheel is a tool used for grinding, which uses diamond abrasive as the main grinding medium and fixes it to a matrix with a bonding agent. Diamond has extremely high hardness and wear resistance, and is the hardest substance in nature. This allows diamond grinding wheels to effectively grind various high-hardness materials, such as cemented carbide, ceramics, optical glass, and gemstones, while maintaining good grinding accuracy and surface quality during the grinding process.

[0003] Existing diamond grinding wheels have some shortcomings in use. Traditional diamond grinding wheels often generate a large amount of heat on their surface during product processing, requiring timely cooling. Some water-cooled or air-cooled diamond grinding wheel devices may suffer from uneven cooling medium distribution, leading to inconsistent heat dissipation across different parts of the wheel, affecting its overall performance and lifespan. Therefore, we propose a diamond grinding wheel device with high-efficiency heat dissipation to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] Therefore, the purpose of this utility model is to provide a diamond grinding wheel device with high-efficiency heat dissipation function, which can solve the technical problem that the uneven distribution of cooling medium in existing grinding wheels leads to different heat dissipation effects in different parts of the grinding wheel, affecting the overall performance and service life of the grinding wheel.

[0006] To solve the above-mentioned technical problems, this utility model provides a diamond grinding wheel device with high-efficiency heat dissipation function, adopting the following technical solution: It includes a mounting base, with mounting shafts rotatably mounted at both ends of the mounting base, and a grinding wheel disk fixedly mounted on the outer wall of the mounting shafts. A metal disc is sleeved on the outer wall of the grinding wheel disk, and a cavity is formed inside the metal disc, with a cooling structure fixedly installed inside the cavity. The cooling structure includes two annular sleeves fixedly installed inside the metal disc, both annular sleeves being fitted against both sides of the outer wall of the grinding wheel disk. Annular cooling pipes are fixedly installed inside each annular sleeve. A connecting pipe and a liquid outlet pipe are fixedly installed at the upper and lower ends of the two annular cooling pipes, respectively. A diversion pipe is fixedly connected to one end of each of the two connecting pipes, and a sealing structure is provided at one end of the diversion pipe.

[0007] Optionally, the inner wall of the metal disc is provided with placement grooves on both sides, and the two annular sleeves are fixedly installed inside the placement grooves. The annular sleeves are provided with installation grooves inside, and the annular cooling pipe is adapted to the size of the installation grooves and fits against the inner wall of the grinding wheel disc.

[0008] Optionally, the inner wall of the grinding wheel is provided with several toothed grooves and graphite filling blocks are fixedly installed inside each toothed groove. Solenoid valves are fixedly installed on the outer walls of the two connecting pipes and the liquid outlet pipe. One end of the two liquid outlet pipes is fixedly connected to the inside of the collection bucket and the collection bucket is placed on the base.

[0009] Optionally, the outer wall of the metal disc is provided with a polishing groove, and a dust cover and a placement plate are fixedly installed at the upper and lower ends of the polishing groove, respectively.

[0010] Optionally, the sealing structure includes an installation plate fixedly installed on one end of the diversion pipe. The installation plate has a groove inside, and a sealing ring and a sealing gasket are installed inside the groove. A connecting cover is provided above the installation plate, and an external water pipe is fixedly installed on the upper end of the connecting cover.

[0011] Optionally, both the connecting cover and the outer walls of the mounting plate are fixedly installed with protrusions, and both sets of protrusions are threaded with threaded rods inside. The bottom of the connecting cover is fixedly installed with a snap-fit ​​block that is compatible with the groove of the mounting plate.

[0012] In summary, this utility model has at least one of the following beneficial effects: 1. The components such as the distribution pipe, connecting pipe, annular sleeve, annular cooling pipe, liquid outlet pipe, collection bucket, and graphite filling block facilitate the rapid conduction of heat from the grinding wheel surface by setting the graphite filling block. At the same time, coolant is injected into the distribution pipe through an external water pipe. The coolant flows into the annular cooling pipe through the connecting pipe, causing it to absorb the heat generated by the grinding wheel. Finally, it flows out from the liquid outlet pipe and is collected and recycled in the collection bucket. This helps to achieve uniform water cooling, thereby quickly reducing the temperature of the grinding wheel and avoiding problems such as uneven distribution of cooling medium, which leads to differences in heat dissipation effect in different parts of the grinding wheel. This improves the overall performance and service life of the grinding wheel.

[0013] 2. By setting up components such as external water pipes, connecting covers, mounting plates, threaded rods, sealing gaskets, and sealing rings, the external water pipes are connected to the mounting plates via the connecting covers, which compresses the internal sealing rings and gaskets. Finally, the threaded rods fix and limit the connection between the external water pipes and the mounting plates, which helps to improve the stability of the connection between the external water pipes and the mounting plates, improves the splicing sealing effect, reduces the possibility of cooling medium leakage, and ensures the normal operation of the cooling system.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] The following is in conjunction with the appendix Figure 1 —5. This utility model will be described in further detail.

[0023] Reference Figure 1-5In this embodiment, in order to solve the technical problem that the uneven distribution of cooling medium leads to different heat dissipation effects in different parts of the grinding wheel, which affects the overall performance and service life of the grinding wheel, this utility model discloses a diamond grinding wheel device with high-efficiency heat dissipation function.

[0024] The device includes a mounting base 1, with mounting shafts 10 rotatably mounted at both ends of the mounting base 1, and a grinding wheel 3 fixedly mounted on the outer wall of the mounting shafts 10. A metal disc 2 is fitted on the outer wall of the grinding wheel 3. A cavity is opened inside the metal disc 2, and a cooling structure 5 is fixedly installed inside the cavity. The cooling structure 5 includes two annular sleeves 8 fixedly installed inside the metal disc 2. The two annular sleeves 8 are fitted to both sides of the outer wall of the grinding wheel 3. Annular cooling pipes 53 are fixedly installed inside the annular sleeves 8. A connecting pipe 55 and a liquid outlet pipe 56 are fixedly installed at the upper and lower ends of the two annular cooling pipes 53, respectively. A diversion pipe 52 is fixedly connected to one end of each of the two connecting pipes 55, and a sealing structure 4 is provided at one end of the diversion pipe 52.

[0025] Specifically, the inner walls of the metal disc 2 are provided with placement grooves 81 on both sides, and two annular sleeves 8 are fixedly installed inside the placement grooves 81. The annular sleeves 8 are provided with mounting grooves 82 inside, and the annular cooling pipe 53 is adapted to the size of the mounting grooves 82, and the annular cooling pipe 53 is in contact with the inner wall of the grinding wheel disc 3.

[0026] This facilitates the fixing of the two annular sleeves 8 inside the metal disk 2, causing the annular cooling pipe 53 inside the annular sleeve 8 to fit against the inner wall of the grinding wheel disk 3, thus facilitating effective cooling of the grinding wheel disk 3.

[0027] Specifically, the inner wall of the grinding wheel 3 has several grooves 31, and each groove 31 is fixedly installed with a graphite filling block 32. The outer walls of the two connecting pipes 55 and the liquid outlet pipe 56 are fixedly equipped with solenoid valves 54. One end of the two liquid outlet pipes 56 is fixedly connected to the inside of the collection bucket 51, and the collection bucket 51 is placed on the base.

[0028] By setting multiple graphite filling blocks 32 inside the grinding wheel 3, graphite has good thermal conductivity and can quickly conduct heat away from the surface of the grinding wheel. The collection bucket 51 facilitates the collection, recycling and reuse of the cooling medium after use, thus saving resources.

[0029] Specifically, the outer wall of the metal disc 2 is provided with a polishing groove, and a dust cover 6 and a placement plate 7 are fixedly installed at the upper and lower ends of the polishing groove, respectively.

[0030] The placement plate 7 is set up to facilitate the stable placement of the product. At the same time, when the product is polished, the dust cover 6 is used to protect it from the debris generated, so as to avoid the debris flying and causing injury to the staff.

[0031] Specifically, the sealing structure 4 includes a mounting plate 43 fixedly installed on one end of the diversion pipe 52. The mounting plate 43 has a groove inside, and a sealing ring 47 and a sealing gasket 46 are installed inside the groove. A connecting cover 42 is provided above the mounting plate 43, and an external water pipe 41 is fixedly installed on the upper end of the connecting cover 42.

[0032] This facilitates a relatively sealed connection between the external water pipe 41 and the branch pipe 52, avoiding problems such as leakage of cooling medium caused by poor connection sealing and improving its sealing effect.

[0033] Specifically, both sides of the outer wall of the connecting cover 42 and the mounting plate 43 are fixedly installed with protrusions 45, and both sets of protrusions 45 are threadedly connected with threaded rods 44. The bottom of the connecting cover 42 is fixedly installed with a snap-fit ​​block 48, and the snap-fit ​​block 48 is adapted to the groove of the mounting plate 43.

[0034] By tightening the connecting cover 42 and the mounting plate 43 relative to each other during installation, and by using two sets of threaded rods 44 to fix them in relative positions, the installation stability of the connecting cover 42 and the mounting plate 43 is improved.

[0035] The specific working principle is as follows: The product to be processed is placed on the placement plate 7 on the outside of the two metal discs 2, opposite to the grinding wheel 3. The external power supply is turned on, and the grinding wheel 3 at both ends of the mounting base 1 is driven to rotate to process the product. Over a long period of time, the surface temperature of the grinding wheel 3 rises rapidly. Multiple grooves 31 are set inside the grinding wheel 3, and graphite filler blocks 32 are placed in the grooves 31 to facilitate a certain heat dissipation effect on the grinding wheel 3. At the same time, the operator connects the external water pipe 41 to the mounting plate 43 to make the coolant flow through the diversion pipe 52 into the two connecting pipes 55. By closing the two solenoid valves 54 on the two outlet pipes 56, the coolant in the connecting pipes 55 flows along the annular cooling pipe 53 under the action of gravity, which facilitates uniform cooling of the inner wall of the grinding wheel 3. After cooling is completed, the lower solenoid valve 54 is opened to allow the coolant to flow back into the collection tank 51 through the two outlet pipes 56 for recycling and reuse, thus achieving uniform cooling of the grinding wheel 3.

[0036] When the external water pipe 41 is connected to the mounting plate 43, the connecting cover 42 on the external water pipe 41 is aligned with the groove in the mounting plate 43, causing the snap-fit ​​block 48 to squeeze the internal sealing ring 47 and sealing gasket 46. When the connecting cover 42 is aligned with the mounting plate 43, the two sets of protrusions 45 are fixed and limited by rotating the threaded rod 44, which facilitates the connection and sealing between the external water pipe 41 and the diversion pipe 52, reducing the possibility of cooling medium leakage.
