Description

Technical Field

[0001] This application relates to the field of grinding disc technology, and more particularly to a grinding disc for stone processing. Background Technology

[0002] Grinding discs are an indispensable core tool in stone processing, mainly used for grinding, polishing, and cutting. However, existing grinding discs have fixed particle sizes, which means that grinding can only be done with a single particle size. Grinding discs need to be replaced at different grinding stages. The replacement process requires finding the correct grinding disc, installing and adjusting it, and ensuring proper installation and concentricity, which increases the operator's working time. At the same time, it leads to companies stocking grinding discs of various mesh sizes to meet production needs, resulting in increased operating costs. Utility Model Content

[0003] The purpose of this invention is to provide a grinding disc for stone processing in order to solve the above-mentioned problems.

[0004] The technical solution of this application is implemented as follows:

[0005] This application provides a grinding disc for stone processing, including a disc body with a connecting hole, a convex disc portion provided on the disc body, a plurality of convex disc portions provided and spaced apart along the circumferential direction of the disc body, a flow channel formed on the disc body by two adjacent sets of convex disc portions, a mounting pad provided on the convex disc portion, a plurality of mounting pads provided and spaced apart on the convex disc portion, and a first grinding block movably mounted on the mounting pad;

[0006] The disc body also has a storage seat, and several storage seats are provided and spaced apart along the circumference of the disc body. The storage seats are located between the connecting hole and the convex part. The storage seats have a receiving groove, one end of which extends to the outside of the storage seats. A bearing block is movably installed on the storage seats, and a second grinding block is provided on the bearing block at intervals. The second grinding block is located outside the storage seats.

[0007] The bottom of the storage base is equipped with bolts, and the bolts and the storage base are connected by bearings. The disc body has a through hole corresponding to the position of the bolts, and one end of the bolt is located in the through hole. The inner wall of the through hole is provided with a threaded groove that matches the bolt. By rotating the bolt in the through hole, the storage base can move closer to or further away from the end face of the disc body.

[0008] In one embodiment, the disc body is also provided with heat dissipation holes, and several heat dissipation holes are provided and located between two adjacent sets of seats, with the two ends of the heat dissipation holes extending through to both ends of the disc body.

[0009] In one embodiment, limiting grooves are provided on both sides of the receiving groove, and protrusions matching the limiting grooves are provided on both sides of the bearing block. When the bearing block is located in the receiving groove, the protrusions are embedded in the limiting grooves.

[0010] In one embodiment, the heat dissipation hole has an inclined end, and the diameter of the heat dissipation hole facing the plate body is larger than the diameter of the hole away from the plate body by the cooperation of the inclined end.

[0011] In one embodiment, a connecting shaft is provided at the bottom of the first grinding block, and a mounting pad has a mounting groove. When the bottom end of the first grinding block is in contact with the mounting pad, the connecting shaft is embedded in the mounting groove.

[0012] In one embodiment, the bottom of the bolt is provided with a groove, which allows the bolt to rotate.

[0013] In one embodiment, a magnetic layer is provided on the mounting groove, and a magnetic attraction part is provided at the bottom of the connecting shaft. Through the cooperation of the magnetic layer and the magnetic attraction part, the connecting shaft is magnetically connected to the mounting groove.

[0014] The advantages or beneficial effects of the above technical solutions include at least the following:

[0015] This application discloses a grinding disc for stone processing. By mounting first and second grinding blocks of different particle sizes onto a convex disc and a support block respectively, different grinding precisions can be achieved when the stone comes into contact with the first and second grinding blocks. Since the support block is connected to a mounting base via a bearing and bolts, with the bolts threaded into a through hole in the disc body, when the bolts rotate within the through hole, they can move the mounting base, causing the positions of the second and first grinding blocks to overlap. When grinding the stone, the second grinding block first contacts the stone for coarse grinding. Subsequently, the height of the second grinding block is lower than that of the first grinding block, enabling fine grinding on top of the coarse grinding. Through the cooperation of the second and first grinding blocks and the bolts, two grinding precisions can be achieved on a single disc body, solving the problem of low efficiency caused by existing grinding discs that can only perform precision grinding.

[0032] Reference Figures 1-5 A grinding disc for stone processing includes a disc body 1 with connecting holes 11. The disc body 1 is the basic support component of the entire grinding disc. The main function of the connecting holes 11 is to connect the disc body 1 to a polishing machine. The disc body 1 is provided with several convex disc portions 2, spaced apart along the circumference of the disc body 1. Adjacent sets of convex disc portions 2 form a flow channel on the disc body 1. Since grinding debris is generated during stone grinding, or coolant is added during grinding, the coolant can be promptly delivered to the grinding area through the flow channel to cool and lower the temperature of the grinding block and the stone. Meanwhile, impurities such as grinding chips and dust generated during processing can also be discharged through the flow channel to avoid the accumulation of impurities affecting the polishing effect and play the role of chip removal. The convex plate 2 is provided with a mounting pad 21. Several mounting pads 21 are provided and distributed at intervals on the convex plate 2. The first grinding block 22 is movably mounted on the mounting pad 21. The mounting pad 21 is provided on the convex plate 2 to play the role of buffering and shock absorption, which can reduce the impact of the vibration generated by the first grinding block 22 when polishing the stone on the convex plate 2 and protect the structural strength of the convex plate 2. The convex plate 2 and the disc body 1 are integrally formed.

[0033] The disc body 1 also has a storage seat 3. Several storage seats 3 are provided and are spaced apart along the circumference of the disc body 1. The storage seats 3 are located between the connecting hole 11 and the convex disc 2. The storage seats 3 have a receiving groove 31. One end of the receiving groove 31 extends to the outside of the storage seats 3. A bearing block 32 is movably installed on the storage seats 3. The bearing block 32 is provided with spaced second grinding blocks 321. The second grinding blocks 321 are located outside the storage seats 3. The storage seats 3 are used to install and fix the bearing block 32 and the second grinding blocks 321. One end of the receiving groove 31 extends to the outside of the mounting seat 3, providing space for the installation and movement of the bearing block 32, so that the bearing block 32 can move to a certain extent in the receiving groove 31 to adapt to the unevenness of the stone surface, and the first grinding block 22 and the second grinding block 321 can be replaced with grinding blocks of different grinding particles according to the needs of use.

[0034] The bottom of the storage base 3 is provided with a bolt 33, and the bolt 33 and the storage base 3 are connected by a bearing. The bearing adopts the ball bearing of the prior art. The bearing is designed so that when the bolt 33 rotates, the storage base 3 will not rotate synchronously. The disc body 1 is provided with a through hole 12 corresponding to the position of the bolt 33. One end of the bolt 33 is located in the through hole 12. The inner wall of the through hole 12 is provided with a threaded groove 121 that matches the bolt 33. By rotating the bolt 33 in the through hole 12, the storage base 3 can move closer to or away from the end face of the disc body 1. By rotating the bolt 33 in the through hole 12, the position can be precisely adjusted according to different stone processing needs.

[0035] Based on the above structure, by respectively setting the first grinding block 22 and the second grinding block 321 with different particle sizes on the convex portion 2 and the support block 32, and by rotating the bolt 33 located in the through hole 12, the portion of the bolt 33 located in the through hole 12 can be changed. Since the bolt 33 is connected to the placement seat 3 by a bearing, when the position of the bolt 33 changes, it will drive the placement seat 3 to move vertically. The support block 32, on which the second grinding block 321 is installed, is installed on the placement seat 3, thereby synchronously changing its position, so that the position of the second grinding block 321 and the first grinding block 22 are staggered. When the position of the second grinding block 321 is higher than that of the first grinding block 22, and the particle size of the second grinding block 321 is smaller than that of the first grinding block 22, By installing the disc body 1 with the polishing machine, the second grinding block 321 can first come into contact with the stone material, thereby completing the rough grinding operation of the stone. The impurities generated during grinding can be discharged from the flow channel formed between the convex discs 2. After the rough grinding operation is completed, by rotating the bolt 33 again, the height of the second grinding block 321 is made smaller than the height of the first grinding block 22, so that the stone can be finely ground by the first grinding block 22. Through the cooperation of the bolt 33, the first grinding block 22 and the second grinding block 321, two grinding methods of grit can be achieved on the stone without changing the disc body 1, thereby improving the convenience of grinding, solving the problem that the existing grinding discs have uniform grit, which requires different grinding discs for different operations, and improving processing efficiency.

[0036] In one embodiment, reference is made to Figure 1 , Figure 3 , Figure 4 and Figure 7 The disc body 1 is also provided with heat dissipation holes 13. Several heat dissipation holes 13 are provided and located between two adjacent sets of seats 3. The two ends of the heat dissipation holes 13 extend to the two ends of the disc body 1. During the stone processing, the high-speed rotation of the disc body 1 and the friction with the stone will generate a lot of heat, causing the temperature of the disc body 1 to rise. The heat dissipation holes 13 provide a channel for heat dissipation, so that the heat inside the disc body can be quickly transferred to the external environment through the heat dissipation holes 13. Multiple heat dissipation holes 13 are distributed between adjacent seats. By utilizing the air flow effect generated when the grinding disc rotates, air convection is formed, thereby enhancing the heat dissipation effect, effectively reducing the temperature of the disc body 1, and extending the service life of the grinding disc.

[0037] The heat dissipation hole 13 has an inclined end 131. With the cooperation of the inclined end 131, the diameter of the heat dissipation hole 13 facing the plate 1 is larger than the diameter of the end away from the plate 1. The design of the inclined end 131 changes the cross-sectional shape of the heat dissipation hole 13, so that the air is guided when passing through the heat dissipation hole 13. The large diameter facing the plate 1 facilitates the smooth entry of outside air into the heat dissipation hole 13, while the small diameter away from the plate 1 helps to accelerate the outflow speed of the air, forming a certain suction effect, more effectively guiding the air flow, increasing the air flow rate and velocity through the heat dissipation hole 13 per unit time, thereby taking away more heat and making the temperature of the plate 1 more quickly and effectively controlled.

[0038] In one embodiment, reference is made to Figure 1 , Figure 4 and Figure 7 The receiving groove 31 is provided with limiting grooves 311 on both sides, and the bearing block 32 is provided with protrusions 322 on both sides that match the limiting grooves 311. When the bearing block 32 is located in the receiving groove 31, the protrusions 322 are embedded in the limiting grooves 311. During the operation of the grinding disc, the bearing block 32 needs to bear the weight of the second grinding block 321 and the force generated during processing. The limiting structure can restrict the movement of the bearing block in the horizontal direction and prevent the bearing block 32 from shaking or displacing due to force.

[0039] In one embodiment, reference is made to Figure 1 , Figure 3 , Figure 4 and Figure 6 The bottom of the first grinding block 22 is provided with a connecting shaft 221, and the mounting pad 21 has a mounting groove 211. When the bottom end of the first grinding block 22 is in contact with the mounting pad 21, the connecting shaft 221 is embedded in the mounting groove 211. The cooperation between the connecting shaft 221 and the mounting groove 211 provides a mechanical connection structure for the installation of the first grinding block 22 on the mounting pad 21. After the connecting shaft 221 is embedded in the mounting groove 211, it can restrict the movement of the first grinding block 22 in the horizontal direction, ensuring that the position of the first grinding block 22 on the mounting pad 21 is accurate, and realizing mechanical positioning and connection.

[0040] A magnetic layer 2111 is provided on the mounting groove 211, and a magnetic suction part 2211 is provided at the bottom of the connecting shaft 221. Through the cooperation of the magnetic layer 2111 and the magnetic suction part 2211, the connecting shaft 221 is magnetically connected to the mounting groove 211. Based on the mechanical connection of the connecting shaft 221 embedded in the mounting groove 211, the magnetic attraction further fixes the position of the connecting shaft 221 in the mounting groove 211, preventing the connecting shaft 221 from loosening or falling out of the mounting groove 211 under unexpected circumstances. Furthermore, when installing the first grinding block 22, the magnetic attraction can automatically guide the connecting shaft 221. Align the first grinding block 22 with the mounting groove 211, and generate an adsorption force when the connecting shaft 221 approaches the mounting groove 211. This allows the first grinding block 22 to be quickly positioned and pre-fixed on the mounting pad 21, facilitating accurate subsequent installation and mechanical connection. Furthermore, the combination of magnetic connection and mechanical connection creates a dual fixing effect, making the connection shaft 221 more firmly fixed in the mounting groove 211. Even when the grinding disc rotates at high speed and is subjected to large vibrations, the magnetic attraction can effectively suppress the slight displacement of the connecting shaft 221, reduce the possibility of loosening, and improve the stability of the first grinding block 22 installation.

[0041] In one embodiment, reference is made to Figure 1 and Figure 2 The bottom of the bolt 33 is provided with a groove 331. The bolt 33 can be rotated by the engagement of the groove 331. The groove 331 has the shape of an internal hexagonal hole of existing standard size. The user can rotate the bolt 33 with a standard size hexagonal wrench, thereby changing the position of the holder 3. Furthermore, the connection between the thread on the bolt 33 and the thread groove 121 can ensure the tightness of the connection.
