Description

Technical Field

[0001] This application relates to the field of grinding technology, and in particular to a durable grinding disc. Background Technology

[0002] A grinding machine is a mechanical device that integrates a power system and grinding tools, used for high-precision grinding, lapping, and polishing of workpiece surfaces. It is widely used in industries such as metal processing, semiconductors, and optical glass, and is a core piece of equipment for achieving efficient and precise machining of planes, external cylinders, and centerless surfaces.

[0003] Currently, the grinding machine is driven by a motor to rotate the grinding disc. The disc has multiple mounting holes spaced apart along its circumference. The workpiece is placed in the mounting holes of the disc. There are diamond grinding discs on both the upper and lower sides of the disc. As the disc rotates, the two diamond grinding discs grind both sides of the workpiece.

[0004] As the turntable rotates the workpiece, its surface continuously rubs against the diamond grinding disc, causing it to gradually wear down over time. Furthermore, because the turntable and grinding disc are in close contact, the grinding fluid trapped inside the turntable cannot drain smoothly from the mounting holes. Utility Model Content

[0005] In order to improve the service life of the grinding disc and facilitate the discharge of grinding fluid, this application provides a durable grinding disc.

[0006] The durable grinding turntable provided in this application adopts the following technical solution:

[0007] A durable grinding disc includes a disc body, wherein a plurality of mounting holes are equally spaced along the circumference of the disc body, and a plurality of support blocks are provided on the opposite side walls of the disc body. The ends of the support blocks extend to the outside of the disc body, and the end faces of the support blocks contact the grinding disc and form a drainage gap between the disc body and the grinding disc.

[0008] By adopting the above technical solution, when the turntable body drives the workpiece to rotate, the support block contacts the grinding disc, so that the turntable body and the grinding disc do not come into contact, which reduces the wear of the turntable body and improves the service life of the turntable. At the same time, the drainage gap between the turntable body and the grinding disc facilitates the smooth discharge of grinding fluid from the mounting hole.

[0009] Preferably, the turntable body is provided with a plurality of connecting parts, and the support block is detachably mounted on the turntable body through the connecting parts.

[0010] By adopting the above technical solution, the support block is installed on the turntable body using connectors, which increases the stability of the support block installation and also facilitates the disassembly of the support block.

[0011] Preferably, a plurality of the support blocks are symmetrically arranged on both sides of the turntable body along the axial direction of the turntable body, and a connector is fixedly connected to two symmetrical support blocks on both sides of the turntable body.

[0012] By adopting the above technical solution, one connector fixes two support blocks. When installing and disassembling the support blocks, two support blocks can be installed and disassembled at the same time in a single operation, thereby improving the efficiency of installation and disassembly of the support blocks.

[0013] Preferably, the connector includes a bolt and a nut, a through hole is provided in the support block, the bolt is disposed in one support block, the nut is disposed in another support block, and the bolt passes through the turntable body and is connected to the nut.

[0014] By adopting the above technical solution, bolts and nuts are used to install two support blocks on the symmetrical sides of the turntable body, making the installation of the two support blocks more stable.

[0015] Preferably, multiple mounting slots are symmetrically provided on the opposite side walls of the turntable body, and a connecting hole is provided in the turntable body. The two ends of the connecting hole are connected to two mounting slots, the support block is disposed in the mounting slot, and the bolt passes through the connecting hole.

[0016] By adopting the above technical solution, the mounting groove of the turntable body limits the support block, making the support block more stable when installed in the turntable body.

[0017] Preferably, multiple limiting grooves are symmetrically formed on the opposite side walls of the turntable body, the limiting grooves are connected to the mounting grooves, and a limiting ring is fixedly provided on the outer side wall of the support block away from the turntable body, the limiting ring being located in the limiting groove.

[0018] By adopting the above technical solution, when the support block is installed in the mounting groove, the limiting ring on the support block is installed in the limiting groove, thereby further improving the stability of the support block installation.

[0019] Preferably, the outer wall of the support block has an avoidance ring groove on the side near the limiting ring.

[0020] By adopting the above technical solution, when the limiting ring is installed in the limiting groove, the avoidance ring groove on the support block avoids the turntable body, so that the support block and the turntable body are less likely to interfere at the connection between the mounting groove and the limiting groove.

[0021] Preferably, the plurality of support blocks are arranged in two rings around the circumference of the turntable body, with one ring of support blocks located outside the plurality of mounting holes and the other ring of support blocks located inside the plurality of mounting holes.

[0022] By adopting the above technical solution, the two rings of support blocks are located on the inner and outer sides of the mounting hole respectively to provide support, thereby making the support effect of the support blocks better.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By using the support block, when the turntable body drives the workpiece to rotate, the support block contacts the grinding disc, so that the turntable body and the grinding disc do not come into contact, which reduces the wear of the turntable body and improves the service life of the turntable. At the same time, the drainage gap between the turntable body and the grinding disc facilitates the smooth discharge of grinding fluid from the mounting hole.

[0025] 2. The support block is installed on the turntable body using connectors, which increases the stability of the support block installation and also facilitates the disassembly of the support block;

[0026] 3. The mounting slot of the turntable body limits the support block, making the support block more stable when installed in the turntable body. Attached Figure Description

[0032] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0033] This application discloses a durable grinding turntable.

[0034] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4A durable grinding turntable includes a circular turntable body 1. Multiple mounting holes 2 are evenly spaced along the axial direction of the turntable body 1, and workpieces are placed within these mounting holes 2. Multiple support blocks 3 are detachably and symmetrically mounted on the two side walls of the turntable body 1 along its axial direction via connectors 5. The support blocks 3 are arranged in two rings evenly spaced around the circumference of the turntable body 1, with one ring of support blocks located outside the mounting holes 2 and the other ring located inside. The ends of the support blocks 3 away from the turntable body 1 extend out of the turntable body 1, and the end faces of the support blocks 3 away from the turntable body 1 abut against a grinding disc 12. A drainage gap 4 is formed between the turntable body 1 and the grinding disc 12.

[0035] When the turntable body 1 rotates to perform grinding, it maintains contact with the surface of the grinding disc 12 through several support blocks 3, thereby ensuring that the turntable body 1 and the grinding disc 12 remain in a non-contact state. This effectively avoids direct friction between the turntable and the grinding disc 12, significantly reduces the wear of the turntable body 1, and thus extends its service life.

[0036] Meanwhile, since there is a reasonable drainage gap 4 between the turntable body 1 and the grinding disc 12, the coolant or grinding fluid used in the grinding process can be smoothly discharged through the mounting hole 2 of the turntable body 1. This not only improves the drainage efficiency, but also helps to maintain the cleanliness and cooling effect of the processing area, thereby improving the overall grinding quality and working stability.

[0037] Multiple mounting slots 7 are symmetrically formed on opposite side walls along the axis of the turntable body 1. Each mounting slot 7 corresponds to a support block 3, and the support blocks 3 are installed in the mounting slots 7. Multiple connecting holes 8 are formed inside the turntable body 1, and the two ends of each connecting hole 8 are connected to two symmetrical mounting slots 7.

[0038] A connector 5 fixes two symmetrical support blocks 3 on both sides of the turntable body 1 to the turntable body 1. The connector 5 includes a bolt 51 and a nut 52. Each support block 3 has a through hole 6, and the diameter of the through hole 6 on the side closer to the turntable body 1 is smaller than the diameter on the side farther away from the turntable body 1. The bolt 51 is installed in the through hole 6 of one support block 3, and the nut 52 is installed in the through hole 6 of the other symmetrical support block 3. The bolt 51 passes through the connecting hole 8 and extends into the through hole 6 of the other support block 3, and the bolt 51 and the nut 52 are threadedly connected.

[0039] The connector 5 adopts an integrated locking design, which can simultaneously fix the two support blocks 3 in a predetermined position. During installation or disassembly, the operator only needs to tighten or loosen once to achieve synchronous assembly and disassembly of the two support blocks 3, which significantly reduces operation steps and time, and improves assembly and maintenance efficiency.

[0040] A limiting ring 10 is integrally formed on the outer side wall of the support block 3 away from the turntable body 1, and a limiting groove 9 communicating with the mounting groove 7 is provided on the outer side wall of the turntable body 1. When the support block 3 is installed into the mounting groove 7, the limiting ring 10 is embedded in the limiting groove 9, thereby limiting the support block 3 and improving the stability of the support block 3 installation.

[0041] An clearance groove 11 is provided on the outer side wall of the support block 3 near the limiting ring 10. When the limiting ring 10 is inserted into the limiting groove 9, a necessary gap is formed between the clearance groove 11 on the side wall of the support block 3 and the turntable body 1. This ensures that the two can achieve interference-free nesting at the joint of the mounting groove 7 and the limiting groove 9, effectively preventing rigid contact and interference that may occur during installation.

[0042] The implementation principle of a durable grinding turntable in this application embodiment is as follows: when the workpiece is placed in the mounting hole 2, and the turntable body 1 drives the workpiece to rotate through the mounting hole 2, the support block 3 contacts the grinding disc 12, so that the turntable body 1 and the grinding disc 12 do not come into contact, reducing the wear of the turntable body 1 and improving the service life of the turntable. At the same time, the drainage gap 4 between the turntable body 1 and the grinding disc 12 facilitates the smooth discharge of grinding liquid from the mounting hole 2.

[0043] The above are merely optional embodiments of this disclosure and are not intended to limit this disclosure. Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
