DETAILED DESCRIPTION Example 1

[0036] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0037] The present invention provides a grinding device for high-speed grinding wheel production, which comprises a frame 1 and a support mechanism 2. The frame 1 is provided with a grinding mechanism 11 and a grinding chamber 12. The support mechanism 2 is located inside the grinding chamber 12 to support the grinding wheel workpiece. The support mechanism 2 comprises a support plate 21, a suction cup assembly 22, and a lifting assembly 23. There are multiple suction cup assemblies 22, and the suction cup assembly 22 and the support plate 21 are in the same horizontal plane. The support plate 21 and the multiple suction cup assemblies 22 cooperate with each other to support and fix the grinding wheel workpiece. The lifting assembly 23 is located at the bottom of the grinding chamber 12 to drive the support plate 21 and the suction cup assembly 22 to move up and down.

[0038] In this embodiment, the suction cup assembly 22 includes a suction cup 221 and a first airbag 222. The suction cup 221 is located above the first airbag 222 and connected to the first airbag 222. An air pump 13 corresponding to the first airbag 222 is provided in the grinding chamber 12. The first airbag 222 is inflated by the air pump 13 to apply force to the suction cup 221. The first airbag 222 is made of a wear-resistant, aging-resistant, and well-sealed material such as rubber, silicone, or synthetic rubber, which can ensure that the airbag maintains stable performance and life during long-term use. The diameter ranges from 50 mm to 200 mm. The specific value can be adjusted according to the size of the grinding wheel workpiece to ensure that the airbag can be fully inflated and evenly apply force to the suction cup 221. The height of the first airbag 222 is between 10mm and 50mm, which is enough to make the airbag fully expand when inflated while avoiding wasting space due to being too high. The maximum inflation pressure ranges from 5kPa to 30kPa; the suction cup 221 is made of soft, wear-resistant, oil-resistant, and chemical-resistant materials such as rubber, silicone, or special engineering plastics, which can ensure that the suction cup 221 maintains stable performance and life in harsh working environments. Its diameter ranges from 100mm to 300mm, and the specific value can be determined according to the size of the grinding wheel workpiece. The thickness ranges from 5mm to 20mm, so that the suction cup 221 has a certain rigidity and elasticity, and can remain stable during adsorption and release when needed.

[0039] In this embodiment, the grinding mechanism 11 includes a first grinding component 111 and a second grinding component 112. The first grinding component 111 is located at the top of the grinding chamber 12 to grind the top of the grinding wheel workpiece. The first grinding component 111 includes a first telescopic rod 1111 and a first grinding sheet 1112. The first telescopic rod 1111 is located at the top of the frame 1 and corresponds to the grinding chamber 12 and drives the first grinding sheet 1112 to move up and down to contact the surface of the grinding wheel workpiece. The first grinding sheet 1112 is driven by a motor to rotate to grind the grinding wheel workpiece. The second grinding component The second grinding component 112 is located at one side of the grinding chamber 12. The second grinding component 112 is of arc design. The second grinding component 112 grinds the side of the grinding wheel workpiece. The second grinding component 112 includes a second telescopic rod 1121 and a second grinding sheet 1122. The second grinding sheet 1122 is located at the inner wall of the top opening of the grinding chamber 12. The second telescopic rod 1121 is located at both ends of the second grinding sheet 1122 to drive the second grinding sheet 1122 to move from the inner wall of the top opening of the grinding chamber 12 to the center of the circle to grind the grinding wheel workpiece. The second grinding sheet 1122 is arc-shaped.

[0040] In this embodiment, the lifting assembly 23 is a third telescopic rod, and a first support plate 231 is provided on the top of the lifting assembly 23. A rotating assembly 26 corresponding to the supporting plate 21 and the suction cup assembly 22 is provided on the first support plate 231. The rotating assembly 26 drives the grinding wheel workpiece to rotate through the supporting plate 21 and the suction cup assembly 22, so that the side of the grinding wheel workpiece is ground using the second grinding assembly 112;

[0041] In this embodiment, the rotating assembly 26 includes a rotating disk 261, a first gear 262, and a second gear 263 meshing with the first gear 262. The rotating disk 261 and the first gear 262 are fixedly connected and coaxial, and the second gear 263 is rotated by a motor.

[0042] When the present embodiment is in use, the operator places the grinding wheel workpiece on the supporting plate 21 and starts the air pump 13. The first airbag 222 starts to inflate to squeeze the suction cup 221. The suction cup 221 is tightly adsorbed on the lower surface of the grinding wheel workpiece to fix and limit the grinding wheel workpiece, and the first airbag 222 can effectively alleviate the shaking generated during grinding. The first telescopic rod 1111 drives the first grinding plate 1112 to move downward, and the motor drives the first grinding plate 1112 to rotate to grind the upper surface of the grinding wheel workpiece. After the grinding of the upper surface of the grinding wheel workpiece is completed, the lifting assembly 23 drives the supporting mechanism 2 and the grinding wheel workpiece to move downward to correspond to the second grinding plate 1122. The motor drives the second gear 263 to rotate, and the second gear 263 and the first gear 262 are meshed with each other. The first gear 262 drives the turntable 261 to rotate, thereby realizing the circular rotation of the grinding wheel workpiece, and the second telescopic rod 1121 drives the second grinding plate 1122 to move toward the outer side of the grinding wheel workpiece to grind the outer side of the grinding wheel workpiece.

[0043] Compared with the prior art, the support plate 21 and the plurality of suction cup assemblies 22 cooperate with each other to more effectively support and fix the grinding wheel workpiece, ensuring that the grinding wheel workpiece will not move or shake during the grinding process, thereby improving the grinding accuracy and stability. The lifting assembly 23 allows the support mechanism 2 and the grinding wheel workpiece to move in the vertical direction, which is convenient for alignment with different grinding assemblies. The rotating assembly 26 enables the grinding wheel workpiece to rotate in a circle during the grinding process, ensuring the uniformity and consistency of the side grinding, and improving the production efficiency and grinding quality. Example 2

[0044] In the above embodiment, the suction cup assembly 22 limits and fixes the grinding wheel workpiece, but due to the inconsistent diameters of the grinding wheel workpiece during use, if the outer ring diameter of the suction cup assembly 22 is larger than the diameter of the grinding wheel workpiece, the second grinding plate 1122 is easy to contact with the suction cup assembly 22 during the process of grinding the outer edge of the grinding wheel workpiece, causing damage to the suction cup assembly 22. Therefore, the embodiment of the present application optimizes the support mechanism 2 to a certain extent based on the above embodiment.

[0045] In this embodiment, multiple suction cup assemblies 22 are linearly distributed in a circle around the support plate 21 from the inside to the outside to form multiple circles of suction cup assemblies 22, and a corresponding connector 24 is provided at the bottom of each circle of suction cup assemblies 22. The suction cup assemblies 22 and the connector 24 are connected through a first support assembly 27. The connector 24 and the first support assembly 27 are connected to the air pump 13, and the air pump 13 inflates the first airbag 222 through the connector 24 and the first support assembly 27.

[0046] The bottom of the connector 24 and the second support plate 25 are slid up and down by a second support assembly 28. The connector 24 is fixedly connected to the first support assembly 27 to drive the suction cup assembly 22 to move up and down. The second support assembly 28 includes a roller screw 281 and a slider 282. The second support plate 25 is provided with a plurality of horizontal slide grooves corresponding to the slider 282. The slide grooves are located on the second support plate 25 and are evenly distributed around the circumference. The slider 282 is located inside the slide groove for sliding. A protrusion is provided at the bottom of the connector 24. The protrusions on the connector 24 are linearly arranged in the slide groove. The roller screw 281 is driven by a motor to have a threaded sleeve connected thereon. The sleeve and the slider 282 are connected by a first connecting rod 283. The two ends of the first connecting rod 283 are hinged to the slider 282 and the screw sleeve. The slider 282 slides in the slide groove through the first connecting rod 283. The end of the slider 282 close to the protrusion is in a cut shape.

[0047] When in use, the present embodiment places the grinding wheel workpiece on the support plate 21, the motor drives the roller screw 281 to rotate, the roller screw 281 drives the screw sleeve to move up and down, the screw sleeve drives the first connecting rod 283 to apply force to the slider 282 so that the slider 282 slides horizontally in the slide groove, and the slider 282 squeezes the protrusion from the inside to the outside during the sliding process, driving the connector 24 and the suction cup assembly 22 to move upward to limit and fix the grinding wheel workpiece. When in use, the sliding distance of the slider 282 is controlled according to the size of the diameter of the grinding wheel workpiece so that the diameter of the raised outer ring suction cup assembly 22 is slightly smaller than the diameter of the grinding wheel workpiece. In this way, a good fixing effect can be achieved during the grinding process and it can also be ensured that the second grinding sheet 1122 will not cause damage to the suction cup assembly 22.

[0048] Compared with the prior art, the system can automatically adjust the height and distribution of the suction cup assembly 22 through the motor-driven roller screw 281 and slider 282 mechanism to adapt to grinding wheel workpieces of different diameters, and can handle workpieces of various specifications, reducing the need for equipment replacement and adjustment, and improving production efficiency and equipment utilization. In actual operation, if the size of the workpiece changes slightly or requires more precise adjustment, the system can respond quickly and make dynamic adjustments to ensure that the workpiece is always stably and effectively fixed. The suction cup assembly 22 is distributed linearly from the inside to the outside of the support plate 21. This layout ensures that the pressure on the workpiece during the grinding process is evenly distributed, avoids deformation or damage of the workpiece caused by excessive local pressure, reduces vibration and movement of the workpiece during the grinding process, improves processing accuracy and safety, and also reduces the problem of uneven grinding caused by workpiece movement or vibration. And because the position and height of the suction cup assembly 22 can be accurately adjusted according to the size of the workpiece, the grinding sheet can be closer to the edge of the workpiece for grinding, thereby improving grinding efficiency and processing quality. Example 3

[0049] In the above embodiment, the suction cup assembly 22 limits and fixes the grinding wheel workpiece, but during use, the surface of the grinding wheel workpiece is rough and uneven, which can easily cause the suction cup 221 to leak during the adsorption process, causing the grinding wheel workpiece to loosen, affecting the grinding effect of the grinding wheel workpiece. Therefore, the embodiment of the present application optimizes the suction cup assembly 22 based on the above embodiment.

[0050] In this embodiment, the suction cup assembly 22 also includes a flexible edge ring 223 and a fixed protrusion 224. The flexible edge ring 223 is a circular structure with a negative pressure tube 2231 in the center. A negative pressure mechanism connected to the negative pressure tube 2231 is provided in the grinding cavity 12. The suction cup 221 is located in the middle of the flexible edge ring 223 and is distributed in a ring shape on the outside of the negative pressure tube 2231. The fixed protrusion 224 is a plurality of fixed protrusions 224 located on the outside of the suction cup 221 on the flexible edge ring 223 and is evenly distributed in a circle. The fixed protrusion 224, the suction cup 221 and the upper surface of the flexible edge ring 223 are fixedly connected.

[0051] When the present embodiment is in use, the negative pressure mechanism starts to work synchronously when the suction cup 221 is adsorbed on the lower surface of the grinding wheel workpiece, and the air in the suction cup 221 is extracted through the negative pressure tube 2231 to realize the negative pressure in the negative pressure tube 2231, thereby enhancing the adsorption ability of the suction cup 221 on the surface of the grinding wheel workpiece, and during the adsorption process, the fixed protrusion 224 of the suction cup 221 contacts the lower surface of the grinding wheel workpiece, increasing the friction with the grinding wheel workpiece, further ensuring the contact between the grinding wheel workpiece and the support mechanism 2, avoiding the shaking of the grinding wheel workpiece, and improving the quality during grinding.

[0052] Compared with the prior art, the air in the suction cup 221 can be effectively extracted through the cooperation of the negative pressure mechanism and the negative pressure tube 2231 to form a negative pressure, thereby greatly enhancing the adsorption capacity of the suction cup 221 on the surface of the grinding wheel workpiece, ensuring that the grinding wheel workpiece can be stably fixed on the support mechanism 2 during the grinding process, avoiding the movement or falling off of the workpiece due to weak adsorption, and the design of the fixed convex point 224 further increases the contact area and friction between the suction cup assembly 22 and the grinding wheel workpiece. The fixed convex point 224 contacts the lower surface of the grinding wheel workpiece, plays an additional fixing role, and effectively prevents the grinding wheel workpiece from being stuck. The wheel workpiece shakes during the grinding process, thereby improving the grinding accuracy and quality, and the stable adsorption and support also reduce the noise and vibration caused by the shaking of the workpiece, and improve the working environment. The suction cup 221 is located in the middle of the flexible edge ring 223 and is distributed in a ring shape on the outside of the negative pressure tube 2231, so that the suction cup 221 can adsorb the grinding wheel workpiece more evenly, avoiding deformation or damage of the workpiece caused by uneven distribution of adsorption force. At the same time, the design of the flexible edge ring 223 also increases the flexibility and adaptability of the suction cup assembly 22, so that it can better fit grinding wheel workpieces of different shapes and sizes. Example 4

[0053] In the above embodiment, the suction cup assembly 22 limits and fixes the grinding wheel workpiece, but when in use, the grinding wheel workpiece is ground by the grinding mechanism 11, and the grinding wheel workpiece will vibrate. The suction cup assembly 22 contacts the lower surface of the grinding wheel workpiece, and the suction cup assembly 22 is easily damaged due to friction during the vibration of the grinding wheel workpiece. Therefore, the embodiment of the present application optimizes the suction cup assembly 22 to a certain extent based on the above embodiment.

[0054] In this embodiment, the interior of the flexible edge ring 223 is a hollow structure with a first cavity, a second airbag 2232 distributed in an annular manner is provided at the bottom of the first cavity, a filler is provided above the second airbag 2232, and the filler can be oil or water. The upper surface of the flexible edge ring 223 is a flexible material;

[0055] In this embodiment, the first support assembly 27 includes a first support rod 271 and a second support rod 272. The second support rod 272 passes through the first support rod 271 and is coaxial with the first support rod 271. There is a gap between the outer wall of the second support rod 272 and the inner wall of the first support rod 271. An annular partition 241 is provided in the connector 24. The partition 241 divides the interior of the connector 24 into a second cavity and a third cavity. The second cavity is located at the top. The top of the first support rod 271 is connected to the first airbag 222, and its bottom is located inside the second cavity. The top of the second support rod 272 is connected to the second airbag 2232, and its bottom is located inside the third cavity. The air pump 13 is connected to the corresponding connector 24 by providing a plurality of ventilation pipes 131. The ventilation pipes 131 are respectively provided with air outlets and control valves corresponding to the second cavity and the third cavity.

[0056] When in use, the air pump 13 is used to inflate the second cavity and the third cavity in the connector 24, and then the first support rod 271 and the second support rod 272 are used to inflate the first airbag 222 and the second airbag 2232 respectively so that the first airbag 222 and the second airbag 2232 can work. The air intake of the first support rod 271 and the second support rod 272 is controlled by the control valve on the ventilation pipe 131. After the second airbag 2232 is inflated, it squeezes the filler in the first cavity, and the filler expands the upper surface of the flexible edge ring 223, so that the suction cup 221 is in close contact with the surface of the grinding wheel workpiece, and the filler can effectively reduce the vibration generated by the grinding mechanism 11 during the grinding process to ensure the grinding quality of the grinding wheel workpiece.

[0057] Compared with the prior art, the air pump 13 is used to inflate the second airbag 2232 to expand it and squeeze the filler (such as oil or water) in the first cavity so that the upper surface of the flexible edge ring 223 can fit closely to the surface of the grinding wheel workpiece, thereby improving the grinding accuracy and quality. When the filler is squeezed, it can effectively absorb and disperse the vibration generated during the grinding process, further ensuring the grinding quality of the grinding wheel workpiece. The air intake of the first support rod 271 and the second support rod 272 can be precisely controlled by the control valve on the ventilation pipe 131. The operator can adjust the expansion degree of the airbag according to actual needs, thereby achieving fine control of the grinding force, which not only improves the grinding quality and efficiency but also improves stability and reliability.

[0058] The present invention and its embodiments are described above, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it and do not deviate from the purpose of the invention, they can creatively design a structure and embodiment similar to the technical solution, which should fall within the protection scope of the present invention.
