Description

Technical Field

[0001] This utility model relates to the field of glass processing technology, specifically to a high-speed grinding wheel for glass processing. Background Technology

[0002] In the field of glass deep processing, especially in the grinding of high-precision electronic and optical glass, the performance of high-speed grinding wheels directly determines processing efficiency and finished product quality. Traditional grinding wheels are mostly made of a single material (such as ordinary alumina or silicon carbide). Although they have a certain cutting ability, they are prone to breakage or glass surface burns at high speeds (such as above 12 m / min) due to the high brittleness of the material and uneven heat conduction. In addition, the connection strength between the grinding wheel and the mounting base is insufficient, and long-term high-speed rotation can easily cause structural fatigue and shorten service life.

[0003] In existing technologies, cutting fluid circulation systems often achieve cooling through external spraying. However, the lack of a directional flow guidance structure inside the grinding wheel makes it difficult for the cutting fluid to fully penetrate the grinding contact area, resulting in low cooling efficiency, significant local temperature rise in the glass, and a tendency to generate microcracks or edge chipping. Some grinding wheels have attempted to add internal flow channels, but this has not solved problems such as chip backflow blockage and flow channel wear, and has instead exacerbated the risk of grinding wheel imbalance. On the other hand, while the rigid connection design between the grinding wheel and the base improves stability, the difference in the thermal expansion coefficients of the materials can easily lead to stress concentration under high-speed thermal loads, causing cracks at the connection. Therefore, there is a need for a high-speed grinding wheel for glass processing. Utility Model Content

Through material innovation, structural optimization and functional synergy, this grinding wheel has achieved significant improvements in processing efficiency, finished product quality, equipment life and operational stability. It is suitable for high-precision glass processing scenarios and solves the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-speed grinding wheel for glass processing, comprising a grinding wheel seat, a grinding wheel mounted on the top of the grinding wheel seat for grinding processing, and a reinforcing seat welded at the connection between the grinding wheel seat and the outer arc surface of the grinding wheel;

[0006] The grinding wheel holder and the grinding wheel are connected by a grinding wheel cavity, and a positioning base plate is provided at the bottom of the grinding wheel cavity inside the grinding wheel holder;

[0007] The outer arc surface of the grinding wheel seat is provided with several sets of dewatering ports through the inner cavity of the grinding wheel at equal arcs, and the inner wall of the positioning base plate is provided with several sets of water tanks corresponding to each set of dewatering ports.

[0008] Preferably, the bottom center of the grinding wheel holder extends outward to form a connecting seat for connecting a locking structure, and the bottom surface of the grinding wheel holder has a set of auxiliary insertion holes on both sides of the connecting seat for limiting the position of the grinding wheel holder.

[0009] Preferably, the grinding wheel surface is provided with several sets of grinding grooves of equal curvature to enhance cutting efficiency;

[0010] The depth of the grinding groove will not penetrate the entire grinding wheel.

[0011] Preferably, the positioning base plate is integrally formed inside the grinding wheel cavity, and the positioning base plate has a height that is higher than the bottom of the dewatering port;

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides: a high-speed grinding wheel for glass processing, such as... Figures 1-4 As shown, the device includes a grinding wheel holder 1, a grinding wheel 5 mounted on the top of the grinding wheel holder 1 for grinding, and a reinforcing seat 4 welded to the outer arc surface connection between the grinding wheel holder 1 and the grinding wheel 5. The grinding wheel holder 1 itself is designed with diamond material, silicon carbide and ceramic abrasives, which has high strength and high toughness and can be heat treated and tempered to improve performance. The grinding wheel 5 is designed with diamond material, silicon carbide and ceramic abrasives, which has high hardness but high brittleness and good thermal conductivity. In addition, the connection between the grinding wheel holder 1 and the grinding wheel 5 is reinforced by the reinforcing seat 4, which is made of aluminum alloy material, which can greatly improve the connection strength between the grinding wheel holder 1 and the grinding wheel 5.

[0025] A grinding wheel cavity 7 is provided between the grinding wheel holder 1 and the grinding wheel 5. A positioning base plate 8 is provided at the bottom of the grinding wheel cavity 7 inside the grinding wheel holder 1. The grinding wheel cavity 7 is integrally formed between the grinding wheel holder 1 and the grinding wheel 5 to ensure the inflow of cutting fluid during the cutting process and to ensure the stability and durability of the cutting process. The positioning base plate 8 is provided to prevent the cutting fluid from bringing in chips and causing wear during the rotation of the device. Therefore, the positioning base plate 8 is made of a high-strength material.

[0026] The outer arc surface of the grinding wheel holder 1 is provided with several sets of dewatering ports 12 through the inner cavity 7 of the grinding wheel. The inner wall of the positioning base plate 8 is provided with several sets of water distribution tanks 10 corresponding to each set of dewatering ports 12. The dewatering ports 12 can ensure that the cutting fluid entering the device is quickly thrown out, while the water distribution tanks 10 accelerate the flow and circulation of the grinding fluid, reduce the temperature of the glass being ground, reduce glass wear, and improve the utilization rate of the glass.

[0027] This grinding wheel is used in a high-speed double-sided grinding machine. For glass with a thickness of 6mm, the grinding speed reaches 12m / min, and the effect of no edge defects and no burns is achieved.

[0028] Preferably, the grinding wheel holder 1 has a connecting seat 2 extending outward from the bottom center for connecting the locking structure. The bottom surface of the grinding wheel holder 1 has a set of auxiliary insertion holes 3 on both sides of the connecting seat 2 for limiting the position of the grinding wheel holder 1. The connecting seat 2 is used to connect with the locking mechanism of the double-sided grinding machine to ensure the stable use of the cutting head. The auxiliary insertion holes 3 on both sides of the connecting seat 2 can further limit the angle of use of the connecting seat 2 during the locking process between the connecting seat 2 and the double-sided grinding machine, thereby improving the overall stability of the cutting tool.

[0029] Furthermore, the grinding wheel 5 has several sets of grinding grooves 6 with equal arcs on its surface to enhance cutting efficiency. The number of grinding grooves 6 on the surface of the grinding wheel 5 and the tilt angle of the contact surface are determined according to specific usage requirements to ensure the stability and efficiency of the cutting process for glass of different specifications.

[0030] The depth of the grinding groove 6 will not penetrate the entire grinding wheel 5, and the depth of the grinding groove 6 can be changed according to the requirements.

[0031] Furthermore, the positioning base plate 8 is integrally formed inside the inner cavity 7 of the grinding wheel. The positioning base plate 8 is higher than the bottom of the dewatering port 12. When the inner cavity 7 of the grinding wheel is opened, the positioning base plate 8 is reserved so that the surface of the positioning base plate 8 is higher than one end of the dewatering port 12.

[0032] The positioning base plate 8 has a positioning through hole 9 through the connecting seat 2. The positioning through hole 9 can ensure that the positioning mechanism of the high-speed double-sided grinding machine can be inserted, and the positioning through hole 9 is closed by the locking mechanism. This further ensures that the cutting fluid can only be discharged through the water distribution groove 10, the docking groove 11 and the dewatering port 12 after entering the inner cavity of the grinding wheel 7.

[0033] It is worth noting that each component water tank 10 has a docking groove 11 at its end. The docking groove 11 and the opening of the dewatering port 12 are completely aligned and fitted. The inner end face of the grinding wheel is provided with a water distribution groove 10, which allows the grinding fluid to flow quickly and cool the grinding wheel at high speed.

[0034] The joints of the water distribution groove 10, the connecting groove 11, and the dewatering port 12 are all ground into a semi-circular transition. The semi-circular transition can enhance the durability of the grinding wheel and increase the service life of the grinding wheel by 10%-20%.

[0035] Specifically, the water distribution groove 10 and the docking groove 11 have the same depth, the bottom of the water distribution groove 10 and the docking groove 11 are at the same height as the lower surface of the dewatering port 12, and the bottom of the water distribution groove 10, the docking groove 11 and the dewatering port 12 are in the same position. This allows the cutting fluid to be quickly thrown out by the rotation of the grinding wheel after entering the inner cavity 7 of the grinding wheel, so as to ensure the overall circulation of the grinding wheel, reduce the temperature of grinding glass, reduce glass wear, and improve the utilization rate of the glass.

[0036] In terms of specific application, this high-speed grinding wheel for glass processing achieves efficient and stable grinding performance through multi-dimensional structural optimization and material combination. In the main structure, the grinding wheel holder is designed with diamond material, silicon carbide, and ceramic abrasives. After tempering and heat treatment, its toughness and load-bearing capacity are improved. A connecting seat and auxiliary insertion hole extend from its bottom to ensure a secure lock and angle limit with the high-speed double-sided grinding machine. The grinding wheel at the top is also designed with diamond material, silicon carbide, and ceramic abrasives, utilizing its high hardness and thermal conductivity to achieve rapid cutting. Adjustable depth and angle grinding grooves are formed on the surface according to the glass specifications to enhance cutting efficiency. An aluminum alloy reinforcing seat is welded at the connection between the grinding wheel holder and the grinding wheel. This material complementarity alleviates stress concentration problems under high-speed rotation and improves the overall structural strength.

[0037] In terms of internal design, the integrally formed inner cavity between the grinding wheel and the grinding wheel provides a flow channel for cutting fluid. Combined with the positioning base plate, it prevents chip backflow and avoids internal wear. The positioning base plate's design, higher than the dewatering port, along with the through-type structure of the water distribution groove, connecting groove, and dewatering port, accelerates the circulation of cutting fluid. The high-speed rotation of the grinding wheel allows for rapid fluid ejection, effectively reducing grinding temperature and minimizing glass chipping and burning. The semi-circular transition at the connection between the water distribution groove and the dewatering port further extends the grinding wheel's lifespan, improving durability by 10%-20%.

[0038] In practical applications, this grinding wheel is compatible with high-speed double-sided grinding machines, and can achieve a grinding speed of up to 12m / min for 6mm thick glass. With the dual protection of cutting fluid circulation cooling and structural rigid support, it ultimately achieves high-quality processing results without missing edges or burns.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
