Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.
[0024] Please refer to Figures 1 to 3The present application proposes a spacer 100 and a grinding device (not shown), wherein the spacer 100 is assembled in a grinding device equipped with a power source (not shown), and the spacer 100 comprises a main body 11 and a partition 12 arranged circumferentially around the main body 11; wherein the main body 11 is transmission-connected to the power source of the grinding device, and the main body 11 is axially provided with a first connecting surface 111 and a second connecting surface 112 opposite to each other, and the diameters of the first connecting surface 111 and the second connecting surface 112 are both smaller than the diameter of a circumferential side surface of the partition 12, and the circumferential side surfaces of the partition 12 and the outer circumferential surface of the main body 11 enclose a first diversion space and a second diversion space, and the partition 12 is used to guide the abrasive of the grinding device into the first diversion space or the second diversion space.
[0025] The connecting surface diameter of the main body 11 of the spacer 100 is smaller than the diameter of the axial side surface of the partition 12, that is, the partition 12 is protruded around the main body 11. The abrasive in the grinding device is usually granular, and the granular abrasive will aggregate when moving in the grinding device. The partition 12 can block part of the abrasive and guide it into the first diversion space or the second diversion space, thereby realizing the diversion effect of the abrasive, dispersing the abrasive in the grinding device more evenly, helping to control the flow and dispersion of the abrasive during the grinding process, and improving the grinding efficiency and product quality.
[0026] Furthermore, according to the actual setting of the grinding device, the diameter of the first connecting surface 111 and the diameter of the second connecting surface 112 can be set differently, resulting in different sizes of the first diversion space and the second diversion space, so that the abrasive has different volume distributions and movement trajectories in different areas. By designing different diameters, the distribution and movement trajectory of the abrasive during the grinding process can be adjusted to achieve a more refined grinding effect. Under different process requirements, by adjusting the diameter difference between the first connecting surface 111 and the second connecting surface 112, it is possible to flexibly adapt to different grinding process requirements, thereby improving the applicability and flexibility of the device.
[0027] In this embodiment, a grinding chamber is provided inside the grinding device, and a spacer 100, a first dispersing member (not shown) and a second dispersing member (not shown) are installed in the grinding chamber. The first dispersing member is installed on the first connecting surface 111, and the second dispersing member is installed on the second connecting surface 112. The first dispersing member and the second dispersing member are both connected to the power source by transmission, and the first dispersing member and the second dispersing member are used to drive the abrasive in the grinding chamber to move.
[0028] Abrasives can be materials with high hardness and good wear resistance, such as corundum, zircon, silicon carbide, aluminum oxide, boron carbide, etc. Abrasives are hard particles used to grind the surface of workpieces. Through the interaction between the abrasive and the workpiece surface, the unsaturated layer, oxide scale, burrs, etc. on the surface of the material can be removed, thereby achieving precise control of the surface roughness, shape and size of the workpiece.
[0029] The dispersion of the abrasive determines the processing range and area of the workpiece, which can ensure that the abrasive particles evenly contact and act on the workpiece surface during the grinding process, avoiding surface quality problems caused by uneven wear. By controlling the dispersion of the abrasive, fine processing of the workpiece surface can be achieved, and processing accuracy and dimensional control capabilities can be improved.
[0030] In order to improve the dispersion of the abrasive, the first dispersing member and the second dispersing member are respectively connected to the first connecting surface 111 and the second connecting surface 112 of the spacer 100. The first dispersing member and the second dispersing member can be rod-shaped, disc-shaped, or other shapes that can disperse the gathered abrasive. The first dispersing member and the second dispersing member are connected to the power source by transmission and can be coaxially driven with the spacer 100. The rotation of the spacer 100 drives the abrasive to be diverted, and the diverted abrasive is dispersed. The multiple components cooperate with each other to enhance the dispersion efficiency of the abrasive and the grinding effect on the workpiece.
[0031] Please refer to Figure 1 In this embodiment, a circumferential side surface of the partition 12 is smoothly connected with the first connecting surface 111 to form a first guide surface 13, and another circumferential side surface of the partition 12 is smoothly connected with the second connecting surface 112 to form a second guide surface 14. The first guide surface 13 guides the abrasive into the first diversion space, and the second guide surface 14 guides the abrasive into the second diversion space. The setting form of smooth transition connection can make the flow of the abrasive into the corresponding diversion space smoother, reduce the resistance and turbulence when the abrasive moves, and improve the guiding effect.
[0032] Please refer to Figure 2 Further, the extension direction of the first guide surface 13 and the extension direction of the first connecting surface 111 have a first guide angle A, the extension direction of the second guide surface 14 and the extension direction of the second connecting surface 112 have a second guide angle B, and the first guide angle A and the second guide angle B are the same or different. In this embodiment, the first guide angle A and the second guide angle B remain the same.
[0033] The size of the first guide angle A and the second guide angle B affects the slope of the first guide surface 13 and the second guide surface 14. The greater the slope of the plane, the faster the abrasive descends. By adjusting the slopes of the first guide surface 13 and the second guide surface 14, the moving speed of the abrasive on the first guide surface 13 and the second guide surface 14 is regulated. In combination with the different diameter settings of the first connecting surface 111 and the second connecting surface 112, different first and second diversion spaces are jointly limited, and the flexibility and application range of the grinding device are improved according to the changes in different grinding processes and requirements.
[0034] Specifically, the first guide angle A and the second guide angle B are both 30° to 60°. For example, they can be 30°, 40°, 50°, 60°, etc. If the first guide angle A and the second guide angle B are too small, the abrasive moves too slowly on the first guide surface 13 and the second guide surface 14, and it is difficult to achieve the flow diversion effect. The intensity of the abrasive grinding the processed product is too small, and the grinding efficiency is not high. If the first guide angle A and the second guide angle B are too large, the abrasive is prone to aggregation.
[0035] Abrasives with larger particle sizes have greater weight, and abrasives of different weights have different distributions on planes with different slopes. When the first guide angle A and the second guide angle B are different, if the first guide angle A is greater than the second guide angle B, on the first guide surface 13 with a larger slope, the abrasive moves faster, and heavier abrasives have greater gravitational potential energy. Abrasives with heavier weight are easier to separate from abrasives with lighter weight, and most of the abrasives reaching the first diversion space are abrasives with larger particle sizes.
[0036] On the second guide surface 14 with a smaller slope, the abrasive moves slowly, and abrasives with different particle sizes are evenly distributed in the second flow distribution space. The first guide angle A and the second guide angle B can be adjusted according to different grinding requirements to achieve the best grinding effect and improve grinding efficiency.
[0037] In some embodiments, the first guide surface 13 is a curved surface or a straight surface, and the second guide surface 14 is a curved surface or a straight surface. The curved surface can be designed with different curvatures according to specific needs to adapt to objects or abrasives of different shapes and sizes, reduce the wear of the objects or abrasives, make the force more uniform, and extend the service life. The straight surface has a simple shape, is easy to design and manufacture, and is more intuitive to operate.
[0038] In this embodiment, the partition 12 is arranged at the middle position of the main body 11 along the axial direction, and the first and second diversion spaces separated are kept equal in size. The specifications and applicable ranges of the first and second dispersing members installed on both sides of the spacer 100 may be the same or different. In other embodiments, the partition 12 may be arranged at different positions of the main body 11 according to the difference between the first and second dispersing members, so as to divide the first and second diversion spaces of different sizes, so as to achieve precise control of the grinding effect.
[0039] Please refer to Figure 3In order to realize the transmission connection between the spacer 100 and the transmission shaft of the power source, the main body 11 is provided with a mounting hole 113 along the axial direction to match the transmission shaft of the power source. The transmission shaft is inserted into the mounting hole 113 to realize the assembly of the power source from the spacer 100, so that the power source drives the spacer 100 to rotate. The power source can be in the form of a motor, an electric motor, etc. The rotating spacer 100 disperses the abrasive in the grinding chamber into the first diversion space and the second diversion space. The first dispersion member and the second dispersion member installed on both sides of the spacer 100 can be coaxially driven, and the abrasive entering the first diversion space and the second diversion space is dispersed for a second time, thereby increasing the distribution range of the abrasive and enhancing the grinding effect and grinding efficiency of the grinding device.
[0040] To facilitate the assembly of the spacer 100 with other components, the first connection surface 111 and the second connection surface 112 are chamfered at the joints with the mounting hole 113. The chamfer can make the connection between the spacer 100, the transmission shaft of the power source, the first dispersed component and the second dispersed component smoother, reduce the resistance during assembly, and improve the assembly efficiency. The chamfer also reduces the friction force on the surface of the spacer 100, reduces the energy loss of the spacer 100 during movement, improves the transmission efficiency, and thus enhances the diversion effect and the grinding effect.
[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
