A high grinding force metal abrasive

Abstract

This application provides a high-grinding-force metal grinding tool, including a disc body for connection to a driver. The disc body has several grinding blocks spaced apart along the circumference of the disc body. When the disc body rotates, the grinding blocks contact the workpiece to perform a grinding operation. The disc body has several evenly distributed hollow sections for heat dissipation. The hollow sections are provided with receiving parts with mounting holes. A brush plate component is movably connected to the mounting holes. When the brush bristles in the brush plate component are located outside the grinding blocks, the grinding blocks first contact the brush bristles when the grinding tool approaches the workpiece, thereby performing a high-precision grinding operation on the workpiece through the brush bristles. Furthermore, the outer periphery of the disc body has a recessed portion and a side plate with grinding blocks is movably mounted thereon. The side plate allows the outer periphery of the disc body to also grind the workpiece during rotation, thereby improving the overall grinding performance of the grinding tool.

Description

Technical Field

[0001] This application relates to the field of metal grinding tool technology, and more particularly to a high grinding force metal grinding tool. Background Technology

[0002] Metal grinding tools are tools made of metal or metal-based materials used to remove excess material, correct shape, and improve surface roughness of workpieces. Their core function is to achieve the processing requirements of workpieces through friction or cutting action between the abrasive and the workpiece. However, existing metal grinding tools only have a single grinding force, which means that the magnitude and intensity of the grinding force cannot be dynamically adjusted according to the processing requirements throughout the entire processing process. This results in poor adaptability to multi-process processing, requiring frequent tool changes and limiting their use. Utility Model Content

[0003] The purpose of this invention is to provide a high-grinding-force metal abrasive to solve the above-mentioned problems.

[0004] The technical solution of this application is implemented as follows: This application provides a high grinding force metal abrasive tool, including a disc body, a shaft hole on the disc body, grinding blocks on the disc body, a number of grinding blocks arranged and spaced apart along the circumferential direction of the disc body, and a number of evenly distributed hollow parts on the disc body, the hollow parts being located between two sets of grinding blocks; The hollow part is provided with a receiving part, and the receiving part is provided with a mounting hole. The mounting hole is movably connected to a brush plate component. The brush plate component includes a support rod, one end of which is connected to a placement seat. The placement seat has a groove and brush bristles are evenly distributed. By inserting the support rod into the mounting hole, the top of the brush bristles is higher or lower than the top of the grinding block. The outer periphery of the disc is provided with a recessed part, and a side plate is movably installed on the recessed part. Grinding blocks are provided on the side plate. Several grinding blocks are provided and evenly distributed on the side of the side plate away from the recessed part. When the side plate is installed on the recessed part, the grinding blocks are located on the outer periphery of the disc.

[0005] In one embodiment, the disc body is further provided with a slot, and a polishing component is movably installed on the slot. The polishing component includes a block, and a polishing disc is provided on the block. By embedding the block into the slot, the polishing disc is located on one side of the block. The polishing disc has a grinding table section, on which abrasive grains are evenly distributed on the side away from the clamping block. When the clamping block is embedded in the clamping slot, part of the grinding table section is located on the outside of the abrasive block.

[0006] In one embodiment, a locking hole is provided on the recessed portion, and a protrusion is provided on the inner side of the side plate corresponding to the position of the locking hole. When the side plate is located in the recessed portion, the protrusion is embedded in the locking hole.

[0007] In one embodiment, a magnetic layer is also provided on the card slot, and a magnetic block is provided on the side of the card block facing the magnetic layer. When the card block is embedded in the card slot, the card block is magnetically connected to the card slot through the cooperation of the magnetic block and the magnetic layer.

[0008] In one embodiment, the inner wall of the mounting hole is provided with a threaded groove, and the outer periphery of the support member is provided with a threaded protrusion that matches the threaded groove. The support rod is threaded into the mounting hole by the engagement of the threaded protrusion and the threaded groove. The rotation of the support rod in the mounting hole causes the brush plate component to move closer to or away from the plate body.

[0009] In one embodiment, the disk body is further provided with heat dissipation holes, and several heat dissipation holes are provided and distributed at intervals along the circumference of the disk body. The heat dissipation holes are located between two adjacent card slots.

[0010] In one embodiment, two sets of recesses are provided and symmetrically distributed on both sides of the disc body. When the two sets of side plates are respectively installed on the two sets of recesses, the two sets of grinding blocks face the same direction.

[0011] The advantages or beneficial effects of the above technical solutions include at least the following: This application discloses a high-grinding-force metal abrasive tool. By connecting a disc body to a driver, the disc rotates in cooperation with the driver. Since grinding blocks are evenly distributed on the disc body, when the disc body drives the grinding blocks toward the workpiece, the rotating disc body can drive the grinding blocks to perform grinding operations on the workpiece. Furthermore, the hollowed-out parts on the disc body can play a role in heat dissipation during grinding. Since the receiving part of the hollowed-out part has mounting holes, when a brush plate component is installed in the mounting holes and the brush bristles in the brush plate component are located outside the grinding blocks, the brush bristles can first contact the grinding blocks and the workpiece. At the same time, the recessed parts on both sides of the disc body can install side plates with grinding blocks, thereby realizing grinding operations with different grinding forces on the workpiece, solving the problem that the existing metal abrasive tools have a single grinding effect and cannot be flexibly adjusted.

[0019] Reference Figures 1-5 A high-grinding-force metal abrasive tool includes a disc body 1 with a shaft hole 11 and grinding blocks 12. Several grinding blocks 12 are arranged and spaced apart along the circumference of the disc body 1. The shaft hole 11 of the disc body 1 is used to connect the drive shaft of the motor. Its precise hole diameter design and center positioning can ensure the coaxiality of the disc body 1 when rotating, and ensure that the grinding trajectory of the grinding blocks 12 on the metal workpiece is always uniform. At the same time, the simultaneous contact of multiple grinding blocks 12 with the workpiece can disperse the grinding force. The disc body 1 has several evenly distributed hollow parts 13. The hollow parts 13 are located between two sets of grinding blocks 12. The design of the hollow parts 13 can reduce the overall weight of the disc body 1. At the same time, the hollow area forms an air circulation channel, which can quickly remove the local heat generated by the grinding of the grinding blocks. A receiving part 131 is provided on the hollow part 13, and a mounting hole 132 is provided on the receiving part 131. A brush plate component 2 is movably connected to the mounting hole 132. The brush plate component 2 includes a support rod 21. One end of the support rod 21 is connected to a placement seat 22. The placement seat 22 has a groove 221 and brush bristles 222 are evenly distributed. By inserting the support rod 21 into the mounting hole 132, the top of the brush bristles 222 is higher or lower than the top of the grinding block 12. The brush bristles 222 are made of metal and are used for further grinding of the workpiece. They can not only clean grinding debris, but also perform fine grinding on the surface of the workpiece. During grinding, if the top of the brush bristles 222 is higher than the grinding block 12, the brush bristles 222 can remove iron and aluminum chips while deburring and micro-polishing the surface of the workpiece after the initial grinding of the grinding block 12. If the workpiece only needs rough grinding, the top of the brush bristles 222 can be adjusted to be lower than the grinding block 12 to avoid excessive grinding of the metal bristles and affecting the size of the workpiece. The outer periphery of the disc body 1 is provided with a recess 14, and a side plate 3 is movably installed on the recess 14. Grinding blocks 31 are provided on the side plate 3. Several grinding blocks 31 are provided and evenly distributed on the side of the side plate 3 away from the recess 14. When the side plate 3 is installed on the recess 14, the grinding blocks 31 are located on the outer periphery of the disc body 1. The grinding blocks 31 are located on the outer periphery of the disc body 1, so that the grinding tool can simultaneously perform radial grinding and peripheral grinding. For the outer periphery of an annular workpiece, circumferential grinding can be performed directly through the peripheral grinding blocks 31. Furthermore, the side plate 3 and the recess 14 are movably connected. When the peripheral grinding blocks 31 are worn, the side plate 3 can be directly removed and replaced, improving the flexibility of use. Two sets of recesses 14 are provided and symmetrically distributed on both sides of the disc body 1. When the two sets of side plates 3 are respectively installed on the two sets of recesses 14, the two sets of grinding blocks 31 face the same direction. During grinding, the disc body 1 rotates and drives the grinding blocks 31 on both sides to work synchronously, forming a double-sided grinding structure. The symmetrical design of the recesses 14 on both sides ensures that the disc body 1 is balanced when rotating, avoids eccentric vibration, and expands the application range of the grinding tool.

[0020] Based on the above structure, by connecting the disc body 1 to the driver and making the grinding block 12 face the workpiece to be processed, the disc body 1 can perform grinding operations on the workpiece when it rotates with the cooperation of the driver. During the grinding process, the hollow part 13 can accelerate the flow of gas, thereby achieving the effect of heat dissipation. After grinding is completed, according to the actual processing needs, the support rod 21 of the brush disc component 2 is installed in the mounting hole 132 on the receiving part 131, so that the bristles 222 in the brush disc component 2 are located on the outside of the grinding block 12. When the grinding wheel comes into contact with the workpiece, the bristles 222 grind the workpiece again, thereby achieving finer grinding of the workpiece and improving the overall grinding force of the grinding wheel. Furthermore, when the side plates 3 are installed on both sides of the disc body 1, the workpiece can also be ground by the grinding block 31 when it is perpendicular to the grinding wheel, thereby improving the flexibility of the grinding method and solving the problem that the existing grinding wheel has a single grinding force, which makes it impossible to dynamically adjust according to processing needs.

[0021] In one embodiment, reference is made to Figure 1 , Figure 2 , Figure 3 and Figure 6 The disc body 1 is also provided with a slot 15, and a polishing component 4 is movably installed on the slot 15. The polishing component 4 includes a block 41, and a polishing disc 42 is provided on the block 41. By embedding the block 41 into the slot 15, the polishing disc 42 is located on one side of the grinding block 12, and after installation, part of it extends out of the outside of the grinding block 12. The polishing disc 42 has a polishing table 421. Abrasive grains are evenly distributed on the side of the polishing table 421 away from the locking block 41. When the locking block 41 is embedded in the locking groove 15, part of the polishing table 421 is located outside the grinding block 12. According to the grinding requirements of the metal workpiece, the locking block 41 of the polishing component is embedded in the locking groove 15 of the disc body 1, so that the polishing disc 42 is positioned on one side of the grinding block 12. During grinding, the grinding block 12 completes the main grinding, and the extended polishing table 421 simultaneously performs fine polishing on the edges, corners and other areas that are difficult to cover by the grinding block 12. The abrasive grains act evenly on the surface of the workpiece to improve the surface finish. If fine polishing is not required, the polishing component 4 can be directly removed and only the grinding block 12 is used for rough grinding, thereby realizing flexible switching of functions to adapt to the needs of different processing stages.

[0022] In one embodiment, reference is made to Figure 1 , Figure 3 and Figure 5 A retaining hole 141 is provided on the recessed part 14, and a protrusion 32 is provided on the inner side of the side plate 3 corresponding to the position of the retaining hole 141. When the side plate 3 is located in the recessed part 14, the protrusion 32 is embedded in the retaining hole 141. When installing the side plate 3, the side plate 3 is aligned with the recessed part 14 of the disc body 1 and pushed in until the protrusion 32 on the inner side of the side plate 3 is completely embedded in the retaining hole 141 of the recessed part 14. The retaining hole 141 and the protrusion 32 form a mechanical limit, which restricts the side plate 3 from sliding or disengaging along the recessed part 14 during the grinding process, and ensures that the side plate 3 provides stable support for the grinding block 12.

[0023] In one embodiment, reference is made to Figure 1 , Figure 3 and Figure 6 The slot 15 is also provided with a magnetic layer 151. The side of the card block 41 facing the magnetic layer 151 is provided with a magnetic suction block 411. When the card block 41 is inserted into the slot 15, the card block 41 is magnetically connected to the slot 15 through the cooperation of the magnetic suction block 411 and the magnetic layer 151. This embodiment is to strengthen and optimize the detachable polishing assembly 4. When the card block 41 is inserted into the slot 15, in addition to the mechanical engagement between the card block 41 and the slot 15, the magnetic suction block 411 will also generate an adsorption force with the magnetic layer 151, forming a double fixation of mechanical engagement and magnetic adsorption. During the grinding process, even if it is subjected to vibration or radial force, the magnetic force can prevent the card block 41 from loosening, ensuring the stable operation of the polishing disc 42. When disassembling, only a pulling force greater than the adsorption force is needed to remove the polishing component 4, so that the grinding method can be flexibly adjusted according to the use needs.

[0024] In one embodiment, reference is made to Figure 1 , Figure 3 and Figure 4 The inner wall of the mounting hole 132 is provided with a threaded groove 1321, and the outer periphery of the support member 21 is provided with a threaded protrusion 211 that matches the threaded groove 1321, thereby realizing a threaded connection. Through the cooperation of the threaded protrusion 211 and the threaded groove 1321, the support rod 21 is threadedly connected to the mounting hole 132. By rotating the support rod 21 in the mounting hole 132, the brush plate component 2 moves closer to or further away from the plate body 1. According to the workpiece thickness or grinding requirements, rotating the support rod 21 will drive the support rod 21 to move axially along the mounting hole 132, thereby adjusting the distance between the brush plate component 2 and the plate body 1. Clockwise rotation moves closer, and counterclockwise rotation moves further away. Moreover, the self-locking nature of the thread allows the support rod 21 to be fixed in any adjustable position without the need for additional locking components.

[0025] In one embodiment, reference is made to Figures 1-3The disc body 1 is also provided with heat dissipation holes 16, which penetrate the upper and lower surfaces of the disc body 1 to form an air circulation channel. Several heat dissipation holes 16 are provided and distributed at intervals along the circumference of the disc body 1. The heat dissipation holes 16 are located between two adjacent sets of slots 15. When grinding with high grinding force, the friction between the grinding block 12 and the workpiece generates a large amount of heat, causing the temperature of the disc body 1 to rise. The heat dissipation holes 16 allow air to form convection when the disc body 1 rotates, quickly carrying away the heat inside the disc body 1, and at the same time reducing the temperature of the area where the grinding block 12 contacts the workpiece.
