Description

Technical Field

[0001] This utility model relates to the field of grinding wheel technology, specifically to a grinding wheel for grinding with low bonding agent, high density, and high hardness. Background Technology

[0002] A grinding wheel, also known as a bonded abrasive, is a type of abrasive tool in which abrasive grains are bonded together by a binder into a specific shape (mostly circular with a central through-hole) and possess a certain strength. It generally consists of abrasive grains, a binder, and pores; these three parts are often referred to as the three essential elements of a bonded abrasive. Low binder content and high density allow the abrasive particles to more effectively contact the workpiece surface, improving grinding efficiency, while high density and high hardness ensure the rigidity and strength of the grinding wheel, making it less prone to deformation during grinding and improving grinding accuracy.

[0003] Existing devices have some drawbacks in use. For example, in the existing technology, the grinding wheel is generally pre-drilled with mounting holes. The grinding wheel is passed through the mounting holes of the grinding wheel through the drive shaft and then fixed with fasteners. However, in actual use, it has been found that when the grinding wheel is used for a long time, the contact surface between the fastener and the grinding wheel will wear due to the frictional resistance generated by grinding, resulting in unstable installation of the grinding wheel and thus affecting the grinding effect. Utility Model Content

[0004] The purpose of this invention is to provide a low-bond, high-density, and high-hardness grinding wheel to solve the problem that when the grinding wheel is used for a long time, the contact surface between the fastener and the grinding wheel will wear due to the frictional resistance generated by grinding, resulting in unstable installation of the grinding wheel and thus affecting the grinding effect.

[0005] This utility model provides the following technical solution: a low-bonded, high-density, and high-hardness grinding wheel, comprising a support vertical plate and a grinding wheel. A mounting and fixing assembly for fixing the support vertical plate is provided on one side of the bottom of the support vertical plate. A rotating rod is horizontally inserted through the top of the support vertical plate. A disc is fixedly connected to one end of the rotating rod. A connecting column is fixedly connected to the side wall of the disc away from the rotating rod. Multiple inserts are fixedly arranged in a ring array on the outer wall of the connecting column. Multiple insertion slots are opened in a ring array on the inner side wall of the grinding wheel. Multiple inserts are inserted into the insertion slots. A limit cap is threadedly connected to the end of the connecting column. A driving assembly for driving the rotating rod is provided at the end of the rotating rod away from the disc.

[0006] As a preferred embodiment of the above technical solution, the installation and fixing assembly includes a first fixing plate and a second fixing plate fixedly connected to the bottom side wall of the supporting vertical plate. The first fixing plate and the second fixing plate are symmetrically arranged vertically. The first fixing plate has a threaded hole, and a suitable threaded rod is inserted into the inner side of the threaded hole. A fixing post is fixedly connected to the bottom end of the threaded rod. A manual knob rod is transversely inserted on the fixing post, and the manual knob rod is fixedly connected to the fixing post.

[0007] As a preferred embodiment of the above technical solution, the driving assembly includes a driven gear fixedly sleeved on the outer wall of the rotating rod, a mounting bracket fixedly connected to the bottom side wall of the support vertical plate, a drive motor fixedly mounted on the mounting bracket, a drive shaft fixedly connected to the output end of the drive motor, a drive gear fixedly sleeved on the outer wall of the drive shaft, and the drive gear meshing with the driven gear.

[0008] As a preferred embodiment of the above technical solution, the rotating rod is rotatably connected to the supporting vertical plate via a bearing.

[0009] As a preferred embodiment of the above technical solution, an abutment disc is fixedly connected to the top end of the threaded rod.

[0010] As a preferred embodiment of the above technical solution, multiple handles are fixed in a ring array on the outer wall of the limiting cover.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, the support plate is fixed to the worktable using an installation and fixing assembly. Then, the inserts on the connecting column are inserted one by one into the sockets of the grinding wheel. After the inserts are fully inserted into the sockets, the limiting cap is threaded to the end of the connecting column. The function of the limiting cap is to prevent the grinding wheel from falling off during rotation. The inserts and sockets ensure the stable installation of the grinding wheel, and the resistance encountered by the grinding wheel during grinding is not transmitted to the sealing cap, ensuring the stable installation of the sealing cap. The combination of the limiting cap, connecting column, inserts and sockets allows for quick disassembly and replacement of the grinding wheel, facilitating the replacement of different types of grinding wheels for grinding operations and adapting to different workpieces.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example

[0019] like Figures 1-4 As shown, this utility model provides a technical solution: a low-bonded, high-density, high-hardness grinding wheel, including a supporting vertical plate 1 and a grinding wheel 11. A mounting and fixing assembly 2 for fixing the supporting vertical plate 1 is provided on one side of the bottom of the supporting vertical plate 1. A rotating rod 12 is horizontally inserted through the top of the supporting vertical plate 1. The rotating rod 12 is rotatably connected to the supporting vertical plate 1 via a bearing. A disc 13 is fixedly connected to one end of the rotating rod 12. A connecting post 14 is fixedly connected to the side wall of the disc 13 away from the rotating rod 12. Multiple inserts 15 are fixedly arranged in a ring on the outer wall of the connecting post 14. Multiple insertion slots 16 are arranged in a ring on the inner side wall of the grinding wheel 11. The multiple inserts 15 are inserted into the insertion slots 16. A limit cover 17 is threadedly connected to the end of the connecting post 14. Multiple handles 171 are fixedly arranged in a ring on the outer wall of the limit cover 17. The handles 171 drive the limit cover 17 to rotate, facilitating gripping. The rotating rod 12 is located away from the disc 13. The end is equipped with a drive assembly 3 for driving the rotating rod 12. In actual use, the support vertical plate 1 is fixed on the worktable using the mounting and fixing assembly 2. Then, the inserts 15 on the connecting column 14 are inserted one by one into the sockets 16 of the grinding wheel 11. After the inserts 15 are fully inserted into the sockets 16, the limiting cover 17 is threaded to the end of the connecting column 14. The function of the limiting cover 17 is to prevent the grinding wheel 11 from falling off during rotation. Through the cooperation of the limiting cover 17, the connecting column 14, the inserts 15 and the sockets 16, the grinding wheel 11 can be quickly disassembled and replaced, which is convenient for changing different types of grinding wheels 11 for grinding operations. The rotating rod 12 is driven to rotate by the drive assembly 3. When grinding, the workpiece to be ground is placed in the appropriate position of the grinding wheel 11 and appropriate pressure is applied for grinding. During the grinding process, the contact pressure and grinding time between the workpiece and the grinding wheel 11 can be adjusted as needed to obtain the desired grinding effect.

[0020] As one implementation method in this embodiment, such as Figure 1 and Figure 2As shown, the mounting and fixing assembly 2 includes a first fixing plate 21 and a second fixing plate 22 fixedly connected to the bottom side wall of the supporting vertical plate 1. The first fixing plate 21 and the second fixing plate 22 are symmetrically arranged vertically. The first fixing plate 21 has a threaded hole 23. A suitable threaded rod 24 is inserted into the inner side of the threaded hole 23. A fixing post 25 is fixedly connected to the bottom end of the threaded rod 24. A manual knob rod 26 is horizontally inserted into the fixing post 25. The manual knob rod 26 is fixedly connected to the fixing post 25. In actual use, firstly, the first fixing plate 21 and the second fixing plate 22 are inserted into the connection of the workbench. Then, the manual knob rod 26 is held and rotated clockwise or counterclockwise to adjust the vertical position of the threaded rod 24. The movement of the threaded rod 24 in the threaded hole 23 will drive the fixing post 25 and the connected parts to move up and down. When the threaded rod 24 moves upward, the top end of the threaded rod 24 will abut against the lower end face of the connection of the workbench, thereby fixing the entire device to the workbench.

[0021] As one implementation method in this embodiment, such as Figure 3 and Figure 4 As shown, the drive assembly 3 includes a driven gear 31 fixedly sleeved on the outer wall of the rotating rod 12. A mounting bracket 32 ​​is fixedly connected to the bottom side wall of the support vertical plate 1. A drive motor 33 is fixedly mounted on the mounting bracket 32. A drive shaft 34 is fixedly connected to the output end of the drive motor 33. A drive gear 35 is fixedly sleeved on the outer wall of the drive shaft 34. The drive gear 35 meshes with the driven gear 31. In actual use, the drive motor 33 is controlled to start and stop by an external controller. The drive motor 33 drives the drive shaft 34 to rotate, thereby causing the drive shaft 34 to drive the drive gear 35 to rotate together. Since the drive gear 35 meshes with the driven gear 31, the rotation of the drive gear 35 will drive the driven gear 31 to rotate together. The rotation of the driven gear 31 will drive the rotating rod 12 to rotate together, thereby achieving the purpose of transmitting the rotational power of the drive motor 33 to the rotating rod 12. Moreover, the number of teeth of the drive gear 35 is greater than that of the driven gear 31, and the rotational speed of the driven gear 31 will be higher than that of the drive gear 35. This transmission method can improve work efficiency and reduce energy consumption.

[0022] As one implementation method in this embodiment, such as Figure 1 and Figure 2 As shown, a contact plate 241 is fixedly connected to the top of the threaded rod 24. The contact plate 241 increases the contact area between the threaded rod 24 and the worktable. A larger contact area means more support points, which helps to reduce loosening or displacement caused by vibration or external force.

[0023] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
