Description

Technical Field

[0001] This invention relates to the field of abrasive manufacturing technology, specifically to a high-performance special grinding disc, manufacturing equipment, and manufacturing method. Background Technology

[0002] In manufacturing, grinding is one of the key processes for achieving precise dimensions and good surface quality. Specialized grinding discs, as the core component of grinding tools, directly affect the efficiency and quality of grinding operations. In grinding disc production, grinding and polishing are crucial for ensuring disc quality. Grinding removes burrs and irregularities from the surface, while polishing improves the surface finish and smoothness, thereby enhancing its performance during use. Furthermore, polishing helps reduce wear during use, extending the disc's service life.

[0003] Existing equipment requires fixing the grinding disc before grinding both sides of the diaphragm. However, the equipment cannot clamp and fix grinding discs of different inner diameters, thus limiting its applicability in practical use.

[0004] Therefore, this invention introduces a high-performance special grinding disc, production equipment, and production method. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a high-performance special grinding disc, production equipment, and production method. It has the advantages of being able to clamp and fix grinding discs of different inner diameters for easy grinding and polishing by subsequent equipment, and being able to quickly push the processed disc out of the processing area, thus solving the problems mentioned in the background art.

[0006] This invention provides the following technical solution: a high-performance special grinding disc production equipment, comprising a machine body, a fixed frame fixedly installed inside the machine body, a rotating shaft rotatably connected to the fixed frame, the rotating shaft passing through and threadedly connected to the lifting sleeve shaft, a connecting arm rotatably connected to the lifting sleeve shaft, an extrusion plate rotatably connected to one end of the connecting arm, and the extrusion plate slidingly connected to the inner wall of the fixed frame, a support rod fixedly connected to the outer surface of the lifting sleeve shaft, a fixed sleeve shaft sleeved at one end of the support rod, a telescopic spring fixedly connected to one end of the support rod, and a telescopic spring fixedly connected to the inner bottom of the fixed sleeve shaft.

[0007] Preferably, the machine body is fixedly connected to a connecting frame, the connecting frame is rotatably connected to a threaded rod, and one end of the threaded rod passes through the connecting frame. The threaded rod passes through the lifting frame and is threadedly connected to the lifting frame. A rotating motor is fixedly installed on the top of the lifting frame, and the output shaft of the rotating motor passes through the top of the lifting frame. One end of the output shaft of the rotating motor is engaged with a rotating sleeve shaft, and a grinding wheel is fixedly connected to the rotating sleeve shaft.

[0008] Preferably, a mounting bracket is fixedly installed at the bottom of the machine body, a drive motor is fixedly connected to the bottom of the mounting bracket, and the output shaft of the drive motor passes through the machine body. A rotating gear is coaxially fixedly connected to one end of the output shaft of the drive motor. The rotating gear meshes with a push rod. A fixed frame is slidably connected to the push rod. The fixed frame is fixedly installed to the machine body. A connecting spring is fixedly connected to the push rod. One end of the connecting spring is fixedly connected to the inner wall of the fixed frame.

[0009] Preferably, the output shaft of the drive motor is coaxially fixedly connected to a gear one, the gear one meshes with a gear two, the gear two is coaxially fixedly connected to a rotating shaft, the gear two meshes with a gear three, and the gear three is coaxially fixedly connected to one end of a threaded rod.

[0010] Preferably, the machine body is fixedly mounted with a transmission frame.

[0011] Preferably, the grinding wheel is made of silicon carbide.

[0012] Preferably, the number of connecting springs is two, and the two connecting springs are arranged symmetrically.

[0013] Preferably, the number of connecting arms is eight, and every two connecting arms form a group.

[0014] A preferred method for producing high-performance special grinding discs:

[0015] Step 1: Place the top of the grinding disc blank that needs to be polished on the support rod;

[0016] Step Two: The starter controls the gears, which are coaxially fixed to the output shaft, to rotate clockwise. This rotates the gear two meshing with the gear and controls the rotating shaft to rotate as well. This causes the lifting sleeve shaft, which is threaded to one end of the rotating shaft, to descend. As the lifting sleeve shaft descends, the four sets of connecting arms rotatably connected to its outer surface extend outward, pushing the extrusion plate along the trajectory of the inner wall of the fixed frame. At the same time, the lifting sleeve shaft also drives the support rod to descend, causing the grinding disc supported at the top of the support rod to descend. The four extrusion plates then abut against the inner diameter of the grinding disc, fixing it in the device. When gear two rotates, it drives gear three to rotate, and the threaded rod, which is coaxially fixed to gear three, also rotates. This controls gear three, which is threaded to the threaded rod, to descend along the trajectory of the inner wall of the connecting frame. This causes the high-speed rotating grinding wheel, driven by the rotating motor, to adhere to the diaphragm and grind it.

[0017] Step 3: After grinding is completed, the output shaft of the drive motor rotates counterclockwise, causing the entire lifting frame to rise slowly. The pressing plate resets and releases the fixing of the grinding disc, while the support rod, under the elastic force of the telescopic spring, lifts the polished grinding disc to its initial position.

[0018] Step 4: Drive the output shaft of the motor to rotate counterclockwise, thereby controlling the push rod that meshes with the rotating gear to move backward. When the rotating gear rotates to a certain extent, its meshing relationship with the push rod is released, and then the push rod is pushed forward rapidly under the elastic force of the connecting spring, thereby pushing the polished grinding disc onto the transfer frame through one end of the push rod.

[0019] Preferably, a high-performance special grinding disc is produced by the above-described production method.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. This high-performance special grinding disc production equipment places the grinding disc to be ground in the processing area of ​​the machine body and supports it with a support rod. Then, the rotation of the output shaft of the drive motor controls the rotation of gear one, which in turn drives gear two meshing with it to rotate and controls the rotation shaft to rotate as well. This causes the lifting sleeve shaft threaded to one end of the rotation shaft to descend. During the descent of the lifting sleeve shaft, the four sets of connecting arms rotatably connected to its outer surface extend outward, thereby pushing the extrusion plate to move outward along the trajectory of the inner wall of the fixed frame. At the same time as the lifting sleeve shaft descends, it also drives the support rod to descend, causing the grinding disc supported on the top of the support rod to descend. Thus, the four extrusion plates abut against the inner diameter of the grinding disc, thereby fixing it in the device.

[0022] 2. This high-performance special grinding disc production equipment, by setting up gear three, when gear two rotates, it will drive gear three to rotate, and drive the threaded rod that is fixedly connected to gear three on the same axis to rotate as well. In turn, it controls gear three, which is threaded to the threaded rod, to descend along the trajectory of the inner wall of the connecting frame, so that the high-speed rotating grinding wheel under the drive of the rotating motor will adhere to the diaphragm and grind it.

[0023] 3. This high-performance special grinding disc production equipment, through the setting of push rods, when the output rotation of the drive motor drives the rotating gear to rotate clockwise, the device will fix the grinding disc at the same time. After the disc is polished, the rotating gear will rotate counterclockwise under the action of the output shaft of the drive motor, which will cause the lifting frame to slowly rise and release the fixing of the grinding disc and reset it. At the same time, the push rod meshing with the rotating gear will move backward. When the rotating gear rotates to a certain extent, its meshing relationship with the push rod will be released, and then under the elastic force of the connecting spring, the push rod will be pushed forward quickly, thus pushing the polished grinding disc to the transfer frame for transport through one end of the push rod.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figure 1-6A high-performance special grinding disc production equipment includes a machine body 1. A fixed frame 2 is fixedly installed inside the machine body 1. A rotating shaft 3 is rotatably connected to the fixed frame 2. The rotating shaft 3 passes through a lifting sleeve shaft 5 and is threadedly connected to the lifting sleeve shaft 5. A connecting arm 6 is rotatably connected to the lifting sleeve shaft 5. An extrusion plate 7 is rotatably connected to one end of the connecting arm 6, and the extrusion plate 7 is slidably connected to the inner wall of the fixed frame 2. A support rod 9 is fixedly connected to the outer surface of the lifting sleeve shaft 5. A fixed sleeve shaft 8 is sleeved on one end of the support rod 9. A telescopic spring 10 is fixedly connected to one end of the support rod 9, and one end of the telescopic spring 10 is fixedly connected to the inner bottom of the fixed sleeve shaft 8. The movement of the extrusion plate 7 along the trajectory of the inner wall of the fixed frame 2 is controlled by the lifting and lowering of the lifting sleeve shaft 5, so that the outer side of the extrusion plate 7 abuts against the inner diameter of the grinding disc, thereby fixing the grinding disc.

[0033] The machine body 1 is fixedly connected to a connecting frame 11, and the connecting frame 11 is rotatably connected to a threaded rod 12. One end of the threaded rod 12 passes through the connecting frame 11 and passes through the lifting frame 25 and is threadedly connected to the lifting frame 25. A rotating motor 13 is fixedly installed on the top of the lifting frame 25, and the output shaft of the rotating motor 13 passes through the top of the lifting frame 25. One end of the output shaft of the rotating motor 13 is engaged with a rotating sleeve shaft 14. A grinding wheel 15 is fixedly connected to the rotating sleeve shaft 14. When the gear 2 4 rotates, it will drive the gear 3 24 that meshes with it and the threaded rod 12 that is fixedly connected to it to rotate together, thereby controlling the lifting frame 25 to rise and fall. This enables the equipment to fix the grinding disc while the grinding wheel 15 driven by the rotating motor 13 descends and adheres to the grinding disc for grinding and polishing.

[0034] The bottom of the body 1 is fixedly mounted with a mounting bracket 16. The bottom of the mounting bracket 16 is fixedly connected with a drive motor 17. The output shaft of the drive motor 17 passes through the body 1. One end of the output shaft of the drive motor 17 is coaxially fixedly connected with a rotating gear 19. The rotating gear 19 meshes with a push rod 21. The push rod 21 is slidably connected to a fixed frame 20. The fixed frame 20 is fixedly mounted to the body 1. The push rod 21 is fixedly connected with a connecting spring 22. One end of the connecting spring 22 is fixedly connected to the inner wall of the fixed frame 20.

[0035] Among them, the output shaft of the drive motor 17 is coaxially fixedly connected to a gear 18, the gear 18 meshes with a gear 4, the gear 4 is coaxially fixedly connected to the rotating shaft 3, the gear 4 meshes with a gear 24, and the gear 24 is coaxially fixedly connected to one end of the threaded rod 12.

[0036] The machine body 1 is fixedly equipped with a transmission frame 23, which can quickly transfer the polished grinding disc to the next grinding disc processing step.

[0037] Among them, the grinding wheel 15 is made of silicon carbide. Silicon carbide itself is a material with extremely high hardness, which is suitable for grinding hard materials.

[0038] There are two connecting springs 22, and the two connecting springs 22 are arranged symmetrically.

[0039] The number of connecting arms 6 is eight, and every two connecting arms 6 form a group.

[0040] One method for producing high-performance special grinding discs:

[0041] Step 1: Place the top of the grinding disc blank support rod 9 that needs to be ground and polished;

[0042] Step 2: Start 17 to control 18, which is coaxially fixed to its output shaft, to rotate clockwise, thereby driving the gear 4 meshing with it to rotate and controlling the rotating shaft 3 to rotate as well. This causes the lifting sleeve shaft 5, which is threaded to one end of the rotating shaft 3, to descend. As the lifting sleeve shaft 5 descends, the four sets of connecting arms 6, which are rotatably connected to its outer surface, will extend outward, thereby pushing the extrusion plate 7 to move outward along the trajectory of the inner wall of the fixed frame 2. At the same time as the lifting sleeve shaft 5 descends, it will also drive the support rod 9 to descend, thereby causing the grinding disc supported at the top of the support rod 9 to descend. Thus, the four extrusion plates 7 will abut against the inner diameter of the grinding disc, thereby fixing it in the device. Then, when the gear 4 rotates, it will drive the gear 24 to rotate, and drive the threaded rod 12, which is coaxially fixed to the gear 24, to rotate as well. This will control the gear 24, which is threaded to the threaded rod 12, to descend along the trajectory of the inner wall of the connecting frame 11, thereby causing the high-speed rotating grinding wheel 15, driven by the rotating motor 13, to adhere to the diaphragm and grind it.

[0043] Step 3: After grinding is completed, the output shaft of the drive motor 17 rotates counterclockwise, causing the lifting frame 25 to rise slowly. The pressing plate 7 resets and releases the fixing of the grinding disc, while the support rod 9, under the elastic force of the telescopic spring 10, lifts the polished grinding disc to its initial position.

[0044] Step 4: The output shaft of the drive motor 17 rotates counterclockwise, thereby controlling the push rod 21, which meshes with the rotating gear 19, to move backward. When the rotating gear 19 rotates to a certain extent, its meshing relationship with the push rod 21 is released, and then the push rod 21 is pushed forward rapidly under the elastic force of the connecting spring 22, thereby pushing the polished grinding disc onto the transmission frame 23 through one end of the push rod 21.

[0045] Among them, a high-performance special grinding disc is obtained by the above-mentioned production method.

[0046] Working principle: First, the grinding disc to be ground is placed in the processing area of ​​the machine body 1 and supported by the support rod 9. Then, the rotation of the output shaft of the drive motor 17 controls the rotation of gear 18, which in turn drives gear 4, which meshes with it, to rotate, and controls the rotation shaft 3 to also rotate. This causes the lifting sleeve shaft 5, threaded to one end of the rotation shaft 3, to descend. During the descent of the lifting sleeve shaft 5, the four sets of connecting arms 6 rotatably connected to its outer surface extend outward, pushing the extrusion plate 7 to move outward along the trajectory of the inner wall of the fixed frame 2. Simultaneously, the lifting sleeve shaft 5 lowers, causing the support rod 9 to descend as well, thus lowering the grinding disc supported at the top of the support rod 9. The four extrusion plates 7 then abut against the inner diameter of the grinding disc, fixing it in place within the device. Then, when gear 4 rotates, it drives gear 3 24 to rotate, and also drives the threaded rod 12, which is coaxially fixed to gear 3 24, to rotate. The threaded rod 12 is then controlled to descend along the trajectory of the gear 24 connected to the threaded rod 12 along the inner wall of the connecting frame 11. This causes the high-speed rotating grinding wheel 15, driven by the rotating motor 13, to adhere to the diaphragm and grind it. Finally, when the output of the drive motor 17 is rotated, it will drive the rotating gear 19 to rotate clockwise. At the same time, the device will fix the grinding disc. After the diaphragm is finished being ground, the rotating gear 19 will rotate counterclockwise under the action of the output shaft of the drive motor 17. This will cause the lifting frame 25 to slowly rise and release the fixing of the grinding disc, allowing it to return to its original position. At the same time, the push rod 21, which is engaged with the rotating gear 19, will move backward. When the rotating gear 19 rotates to a certain extent, its engagement with the push rod 21 will be released. Then, under the elastic force of the connecting spring 22, the push rod 21 will be pushed forward quickly. Thus, the polished grinding disc will be pushed onto the transfer frame 23 through one end of the push rod 21 and transported to the next production process.
