Description

Technical Field

[0001] This utility model relates to the field of grinding disc production and processing technology, and more specifically, to a grinding disc outer coating spraying device. Background Technology

[0002] In the field of grinding disc manufacturing, surface coating with wear-resistant and high-temperature resistant coatings is a key process for improving performance. Grinding discs face intense friction and high-temperature impact during high-speed grinding operations, making the surface prone to wear, oxidation, and even deformation, leading to shortened lifespan or reduced machining accuracy. Spraying ceramic matrix composites can significantly enhance surface hardness, reduce the coefficient of friction, and form a protective layer at high temperatures, inhibiting cracking caused by thermal stress. Furthermore, the uniform and dense coating reduces debris adhesion, maintains the cleanliness of the grinding disc, and thus improves processing stability. Traditional spraying processes cannot simultaneously process coatings on both sides, easily resulting in excessively thick or incomplete coverage on one side, leading to differences in thermal expansion or increased localized wear, affecting overall performance.

[0003] Existing equipment has significant shortcomings in terms of coating uniformity and clamping adaptability. Single-sided spraying requires multiple flipping and positioning, which is cumbersome and prone to human error. The coating interface is prone to thickness fluctuations or areas of weakened adhesion. Furthermore, the clamping mechanism's single adaptability to flange ring thickness may cause workpiece displacement during spraying due to insufficient clamping force, or excessive clamping may cause coating accumulation at the clamping edge, forming stress concentration points. These problems not only reduce the functionality of the coating, but may also cause premature failure of the grinding disc due to local defects, increasing equipment maintenance costs and safety hazards. Therefore, in order to address the above technical problems, a grinding disc external coating spraying device is proposed. Utility Model Content

[0025] 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.

[0026] Please see Figures 1-9 This utility model proposes a grinding disc outer coating spraying device, including an operating table 1. Two sets of symmetrically arranged vertical plates 2 are fixedly connected to the upper side of the operating table 1. A fixed cylinder 3 is fixedly connected to one side of each set of vertical plates 2. A first rotating seat 4 is rotatably connected to the end of one set of fixed cylinders 3, and a second rotating seat 24 is rotatably connected to the end of the other set of fixed cylinders 3. An annular groove is provided at the end of each fixed cylinder 3. Rings are fixedly installed on the outside of both the first rotating seat 4 and the second rotating seat 24, and the rings are slidably connected within the annular groove, achieving limited rotation between the first rotating seat 4 and the fixed cylinder 3, and between the second rotating seat 24 and the fixed cylinder 3. A rotating mechanism is installed on the outside of one set of vertical plates 2, such as... Figures 4-5 As shown, the rotating mechanism includes a mounting base 5, a drive motor 6, and a rotating rod 7. The mounting base 5 is fixedly connected to the outside of the upright plate 2. The drive motor 6 is detachably connected to the inside of the mounting base 5. The mounting base 5 has a power supply circuit installed inside and an external socket, which can provide power when the drive motor 6 is running. The rotating rod 7 is fixedly connected to one side of the drive motor 6, and the end of the rotating rod 7 is fixedly connected to the center position of one side of the first rotating seat 4. This ensures that the rotating seat can achieve circumferential rotation. The rotating rod 7 and the upright plate 2 are rotatably connected.

[0027] A first connecting block 8 is slidably connected to the end of the first rotating seat 4, and a second connecting block 25 is fixedly connected to the outer side of the second rotating seat 24. A clamping mechanism is installed between the first connecting block 8 and the interior of the first rotating seat 4. Figure 6 As shown, the clamping mechanism includes a telescopic rod 9 and a compression spring 10. The telescopic rod 9 and the compression spring 10 are fixedly connected to the inside of the first rotating seat 4, and the ends of the telescopic rod 9 and the compression spring 10 are fixedly connected to one side of the first connecting block 8. There are several sets of telescopic rods 9 and compression springs 10 arranged in an array. The compression spring 10 is sleeved on the outside of the telescopic rod 9, and the compression spring 10 is always in a compressed state. This ensures that the compression spring 10 can always provide the corresponding clamping force when installing grinding discs of different thicknesses.

[0028] Both the first connecting block 8 and the second connecting block 25 are equipped with adsorption mechanisms on their exteriors, such as... Figure 3 As shown, the adsorption mechanism includes a pressure plate 11 and fixed magnets 12. The pressure plate 11 is fixedly connected to the ends of the first connecting block 8 and the second connecting block 25. The circular structure of the pressure plate 11 can be matched with the flange of the grinding disc for clamping, ensuring uniform force. The fixed magnets 12 are fixedly connected to the outside of the pressure plate 11, and the number of fixed magnets 12 is arranged in an array. The fixed magnets 12 on the left and right sides are arranged symmetrically. The fixed magnets 12 on the outside of the two sets of pressure plates 11 have magnetic attraction and clamp the grinding disc body 13. The adsorption force between the fixed magnets 12 can clamp thinner flanges, and when installing thicker flanges, its magnetic attraction can provide a certain clamping pressure.

[0029] The upper limit sliding connection of the control panel 1 is a stand 14, such as... Figure 3 As shown, a sliding groove is provided on the upper side of the operating table 1, and a locking block is fixedly connected to the bottom of the stand 14. The locking block is slidably connected to the sliding groove. The stand 14 achieves limited sliding with the operating table 1 through the locking block and the sliding groove. By cooperating with the locking block and the sliding groove, the slide of the stand 14 can be controlled, so that part of the grinding disc enters the stand 14.

[0030] A partition 15 is fixedly connected inside the support 14, and a storage area is formed below the partition 15, such as... Figure 7 as well as Figure 8 As shown, a feeding pipe 17 is fixedly connected to the outside of the stand 14, and the end of the feeding pipe 17 extends into the storage area. A liquid level sensor 18 is fixedly installed inside the storage area. The material to be sprayed can be introduced into the storage area through the feeding pipe 17. The coating can be epoxy resin + silicon carbide SiC / alumina Al□O□ coating, which has the effects of high wear resistance, strong adhesion and high temperature resistance. The liquid level sensor 18 can sense and monitor the internal coating liquid level to prevent the coating from overflowing due to excessive coating. In addition, a maintenance plate is also provided on the rear side of the stand 14, which makes it easy to open the stand 14 to inspect, replace and clean the internal structure.

[0031] An opening 16 is provided on the lower side of the partition 15. The opening 16 can collect the paint that is not attached to the surface of the grinding disc and let it fall back into the storage area for reuse, effectively avoiding waste of paint.

[0032] A spraying mechanism is symmetrically installed on the upper side of the partition 15, and a material conveying mechanism is installed below the partition 15, such as... Figure 8 as well as Figure 9 As shown, the spraying mechanism includes a material distribution plate 19 and nozzles 20. The material distribution plate 19 is fixedly connected to the upper side of the partition 15 and has a hollow plate structure. The nozzles 20 are fixedly connected to the outside of the material distribution plate 19 and are arranged in an array. The nozzles 20 are connected to the internal space of the material distribution plate 19. The material conveying mechanism includes a material pump 21 and a conduit 22. The material pump 21 is arranged in two sets and is matched with the material distribution plate 19. The conduit 22 is fixedly connected to the outside of the material pump 21 and its end extends through the upper side of the partition 15 into the interior of the material distribution plate 19. The material pump 21 can input the paint stored in the storage area into the material distribution plate 19. Through the pressure of the cavity inside the material distribution plate 19, the paint can be evenly distributed to the nozzles 20 for spraying.

[0033] The outside of the stand 14 is provided with a through groove 23, and the through groove 23 is matched with two sets of adsorption mechanisms. The grinding disc can enter the stand 14 through the through groove 23 and be sprayed with the corresponding coating by the spray nozzles 20 on both sides.

[0034] The working principle of a grinding disc outer coating spraying device based on an embodiment is as follows: During implementation, the operator first moves the pressure plate 11 connected to the first connecting block 8 to separate it from the other pressure plate 11, and then places the flange ring of the grinding disc body 13 between the two pressure plates 11. When the flange ring is thin, the array of fixed magnets 12 outside the pressure plate 11 can form a stable clamping force through magnetic attraction. If the flange ring is thick, the compression spring 10 sleeved on the outside of the telescopic rod 9 is compressed during the movement of the pressure plate 11. The continuous elastic pressure generated by its pre-compression state is used to achieve adaptive clamping, ensuring the universality of clamping grinding discs of different thicknesses.

[0035] After clamping, push the stand 14 to slide along the slide groove of the operating table 1 towards the grinding disc, so that part of the grinding disc completely passes through the through groove 23 of the stand 14 and enters the spraying station. At this time, the feed pump 21 starts, and the wear-resistant and high-temperature resistant coating in the storage area is introduced into the hollow distribution plate 19 through the conduit 22. After being evenly distributed by internal pressure, the uniformly atomized coating is formed by the array of nozzles 20, and the area of ​​the grinding disc exposed in the through groove 23 is sprayed synchronously on both sides. In order for the coating to cover the entire surface of the grinding disc, the drive motor 6 drives a rotating rod 7 to drive a The first rotating seat 4 on the side rotates, and under the longitudinal limiting action of the telescopic rod 9, it can drive the first connecting block 8 on that side to rotate. Meanwhile, the second connecting block 25 on the other side will overcome sliding friction and achieve synchronous rotation under the combined action of the pressure of the compression spring 10 and the magnetic attraction, thereby driving the grinding disc body 13 to rotate continuously around the axis. This allows the coating to be evenly covered on the outer surface of the grinding disc in the circumferential direction. Double-sided coating can be completed without manual flipping, which significantly improves efficiency compared to traditional single-sided spraying equipment. At the same time, it reduces the complexity of operation and ensures the uniformity of coating thickness and process stability.

[0036] 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.
