Description

Technical Field

[0001] This utility model relates to the field of grinding disc technology, and in particular to a high-safety grinding disc. Background Technology

[0002] Grinding discs, as a commonly used grinding tool, play an important role in various industrial fields such as metal processing, stone cutting, and wood polishing.

[0003] During high-speed rotation and cutting, grinding discs are subjected to significant impact forces and vibrations. These impact forces and vibrations can not only cause fatigue damage to the grinding disc body but also cause deformation or fracture of the substrate, thereby shortening the service life of the grinding disc. Furthermore, existing grinding discs are usually exposed when not in use, which can easily cause injury to workers. Utility Model Content

[0004] In existing technologies, grinding discs are subjected to significant impact forces and vibrations during high-speed rotation and cutting. These impact forces and vibrations not only cause fatigue damage to the grinding disc body but also lead to deformation or fracture of the substrate, thereby shortening the service life of the grinding disc. Furthermore, existing grinding discs are usually exposed when not in use, which can easily cause injury to workers. This invention provides a highly safe grinding disc.

[0005] The technical solution adopted by this utility model is: a high-safety grinding disc, comprising a substrate and a grinding disc body. The interior of the grinding disc body is designed with a cavity, and the inner diameter of the grinding disc body is the same as the outer diameter of the substrate. The substrate and the grinding disc body are slidably connected. A buffer assembly is installed between the substrate and the grinding disc body to facilitate shock absorption and buffering of the grinding disc body. The buffer assembly includes a sleeve and a first damping spring. A protective assembly is provided on the outer side of the grinding disc body to facilitate protection of the grinding disc body. The buffer assembly effectively absorbs and buffers the impact force and vibration during the grinding process, protects the grinding disc body and the substrate, improves the safety and service life of the grinding disc, and prevents accidental damage in non-working states, achieving full life cycle safety protection.

[0006] Furthermore, the sleeves are arranged in a linear array and fixedly installed inside the cavity of the grinding disc body. The other end of each of the four sleeves is fixedly connected to one side of the base. The first damping springs are also arranged in a linear array and fixedly installed inside the four sleeves. The multiple sleeves and damping springs provide multi-point support and buffering, ensuring that the impact on the grinding disc body in all directions can be effectively buffered, thereby improving the uniformity and reliability of the shock absorption effect.

[0007] Furthermore, the buffer assembly also includes a mounting groove formed on one side of the substrate. A fixing rod is fixedly installed inside the mounting groove. Two symmetrical sliding blocks are slidably connected to the surface of the fixing rod. A hinge rod is hinged to one side of each of the two sliding blocks. The other end of the two hinge rods is hinged to both sides of the internal cavity of the grinding disc body. A second damping spring is fixedly installed between the two sliding blocks. The hinge rod drives the two sliding blocks to move towards each other, compressing the second damping spring, providing further shock absorption and further reducing the impact of the impact force on the grinding disc body and the substrate.

[0008] Furthermore, the protective component includes a protective frame, inside which are two symmetrical fixing plates. One side of each fixing plate is rotatably connected to a threaded rod via a bearing seat. The threaded rod passes through one side of the protective frame and is threadedly connected to the protective frame. The threaded rods on both sides drive the fixing plates on both sides to move towards each other, so that the protective frame is fixed on the base, protecting the grinding disc body and preventing injury to the workers.

[0009] Furthermore, two symmetrical limiting rods are fixedly installed on one side of each of the two fixing plates. The two limiting rods on the same side pass through one side of the protective frame and are slidably connected to the protective frame, which can limit the fixing plate.

[0010] Furthermore, silicone pads are fixedly installed on the inner surfaces of both fixing plates to increase friction with the substrate and improve the fixing effect.

[0011] Furthermore, an internally threaded tube is fixedly installed on the upper surface of the substrate, which facilitates quick connection and disassembly of the grinding disc with external equipment, improves work efficiency, and ensures the stability and reliability of the connection.

[0012] The beneficial effects of this utility model are:

[0013] This invention effectively absorbs and buffers the impact and vibration during the grinding process through a buffer component, protecting the grinding disc body and substrate, improving the safety and service life of the grinding disc, and solving the problem that existing grinding discs are subjected to large impact and vibration during high-speed rotation and cutting. These impacts and vibrations not only cause fatigue damage to the grinding disc body, but also cause deformation or fracture of the substrate, thereby shortening the service life of the grinding disc.

[0014] Secondly, this utility model prevents accidental injury during non-working conditions through protective components, achieving full life-cycle safety protection and solving the problem that existing grinding discs are usually exposed when not in use, which can easily cause injury to workers.

[0022] The following is in conjunction with the appendix Figures 1-4 The present invention will be further described below.

[0023] To address the problems existing in the background technology, this application proposes the following technical solution: a high-safety grinding disc.

[0024] The specific technical solution includes a substrate 1 and a grinding disc body 2. The grinding disc body 2 has a hollow interior design, and its inner diameter is the same as the outer diameter of the substrate 1. The substrate 1 and the grinding disc body 2 are slidably connected. A buffer assembly 3 is installed between the substrate 1 and the grinding disc body 2 to facilitate shock absorption and buffering of the grinding disc body 2. The buffer assembly 3 includes a sleeve 301 and a first damping spring 302. A protective assembly 4 is provided on the outside of the grinding disc body 2 to facilitate protection of the grinding disc body 2. The buffer assembly 3 effectively absorbs and buffers the impact force and vibration during the grinding process, protects the grinding disc body 2 and the substrate 1, improves the safety and service life of the grinding disc body 2, and the protective assembly 4 prevents accidental damage in non-working states, achieving full life cycle safety protection.

[0025] Reference Figures 1 to 3 As shown, four sleeves 301 are fixedly installed in a linear array inside the cavity of the grinding disc body 2. The other ends of the four sleeves 301 are fixedly connected to one side of the base 1. Four first damping springs 302 are fixedly installed inside the four sleeves 301 respectively. The buffer assembly 3 also includes a mounting groove 303 opened on one side of the base 1. A fixing rod 304 is fixedly installed inside the mounting groove 303. Two symmetrical sliding blocks 305 are slidably connected to the surface of the fixing rod 304. One side of the grinding disc 5 is hinged with a hinge rod 306. The other end of the two hinge rods 306 is hinged to both sides of the internal cavity of the grinding disc body 2. A second damping spring 307 is fixedly installed between the two sliding blocks 305. When the grinding disc body 2 is subjected to an impact force, the first damping spring 302 in the sleeve 301 is compressed, converting kinetic energy into elastic potential energy to achieve initial shock absorption. At the same time, the hinge rods 306 drive the sliding blocks 305 on both sides to move towards each other, compressing the second damping spring 307, which can further dampen and buffer the grinding disc body 2.

[0026] Reference Figure 1 and Figure 4As shown, the protective component 4 includes a protective frame 401. Inside the protective frame 401 are two symmetrical fixing plates 402. One side of each fixing plate 402 is rotatably connected to a threaded rod 403 via a bearing seat. The threaded rod 403 passes through one side of the protective frame 401 and is threadedly connected to it. Two symmetrical limiting rods 404 are fixedly installed on one side of each fixing plate 402. Both limiting rods 404 on the same side pass through one side of the protective frame 401 and are slidably connected to it. Silicone pads 405 are fixedly installed on the inner surfaces of both fixing plates 402. An internally threaded tube 5 is fixedly installed on the upper surface of the base 1. By rotating the threaded rods 403 on both sides, the fixing plates 402 are limited by the limiting rods 404. Therefore, the rotation of the threaded rods 403 causes the fixing plates 402 to move towards each other, thus fixing the protective frame 401 onto the base 1. This ensures that the protective frame 401 completely covers the grinding disc body 2, preventing injury to workers when not in use.

[0027] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview:

[0028] In use, align the internal threaded tube 5 with the drive shaft and tighten it with the appropriate tool to grind the material. When the grinding disc body 2 is subjected to impact force, the first damping spring 302 inside the sleeve 301 is compressed, converting kinetic energy into elastic potential energy to achieve initial shock absorption. At the same time, the hinge rod 306 drives the sliding blocks 305 on both sides to move towards each other, compressing the second damping spring 307, which can further dampen and buffer the grinding disc body 2. After grinding is completed, put the protective frame 401 into the grinding disc body 2, rotate the threaded rods 403 on both sides, and through the limiting action of the limiting rod 404, make the fixing plates 402 on both sides move towards each other and fix them on the base 1.
