Description

Technical Field

[0001] The utility model relates to the technical field of polishing equipment, in particular to a flat grinding decomposition polishing disc capable of rapid disc replacement and a polishing structure. Background Art

[0002] In order to improve the smoothness of the surface of the glass cover plate, a flat grinder is needed to grind and polish the surface of the glass cover plate to reduce its surface roughness. The polishing structure on the traditional flat grinder is a cast iron disc structure polishing disc, which is divided into two upper and lower whole disc polishing discs. A single disc weighs about 400kg. The upper disc is connected to the upper bracket of the machine and fixed by screws, and the lower disc is placed on the supporting structure inside the machine. When changing discs and logistics processing, forklift assistance is required throughout the process. Specifically, when the old disc is removed from the machine, the lower disc needs to be hooked to the upper disc with a hook support, and the two cast iron discs are lifted by the cylinder. After the lower disc is removed by a forklift, the upper disc is lifted by a forklift, the nut is loosened and the upper disc is removed, and the old disc is removed from the machine. When a new plate is installed on the machine, a forklift is needed to lift the upper plate, align the holes with the bracket on the upper end of the machine, and then use screws to fix the upper plate and the bracket together. Then, a forklift is used to lift the lower plate, and four hooks are used to hook the lower plate to the upper plate. The cylinder of the upper plate is lowered to place the lower plate on the internal support structure of the machine, and the plate replacement installation is completed. During logistics processing, a forklift is needed to lift the old plate and put it on the skin scraper. After cleaning, the cast iron plate is removed by a forklift and sent to the employee's workstation for skinning, cutting, hole opening, and slotting. The processed skinning is then dragged to the production line by a forklift.

[0003] Due to the heavy weight of a single disc, employees need to use a forklift to assist during the disc change process, which makes disc change difficult. The entire process of disc change and transportation takes nearly 2 hours. The long disc change time seriously affects the machine utilization rate. During processing and use, if a part of the microdermabrasion disc is damaged, the entire disc needs to be replaced, which wastes a lot of time and manpower. In addition, since a forklift is required to assist during the disc change and transportation process, there is a risk of the cast iron disc falling, which poses a major safety hazard. Utility Model Content

[0004] Based on this, it is necessary to provide a flat grinding decomposition polishing disc and polishing structure that can be quickly changed, with a single disc that is light in weight, easy to change, shortened in changing time, less waste in grinding, and higher in operating safety, in order to address the above shortcomings.

[0005] A fast-changing flat grinding decomposition polishing disc is used for detachable installation on a flat grinding machine grinding disc, comprising at least two fan-shaped discs distributed along a circular path and connected in sequence, wherein the fan-shaped discs are spliced ​​together to form an annular disc-like structure, wherein each fan-shaped disc comprises a first surface adjacent to the flat grinding machine grinding disc, a second surface facing away from the flat grinding machine grinding disc, a first side adjacent to the fan-shaped disc on one side, and a second side adjacent to the fan-shaped disc on the other side, wherein abrasive skin is attached to the second surface of the fan-shaped disc, wherein the shape of the abrasive skin is adapted to the shape of the second surface, wherein each fan-shaped disc is provided with at least one protrusion on the first side, and each fan-shaped disc is provided with at least one recess on the second side which corresponds one to one with the protrusion of the adjacent fan-shaped disc.

[0006] In one embodiment, the number of the fan-shaped platters is 8, and the 8 fan-shaped platters are the same in shape and size.

[0007] In one embodiment, the fan-shaped platter is made of aluminum.

[0008] In one of the embodiments, the weight of a single-piece fan-shaped platter is less than or equal to 2.3 kg.

[0009] In one embodiment, the microdermabrasion is adhered to the second surface.

[0010] The utility model also discloses a polishing structure, comprising a grinding disc fixed on a flat grinder, wherein the grinding disc comprises a polishing surface for polishing a product surface, and the flat grinding decomposition polishing disc is detachably mounted on the polishing surface.

[0011] In one embodiment, the fan-shaped platter of the flat grinding decomposition polishing disc is provided with a plurality of screw holes penetrating the first surface and the second surface, and the grinding disc is provided with a plurality of mounting holes corresponding to the screw holes one by one, and the fan-shaped platter is fixedly connected to the grinding disc by screws penetrating the mounting holes and the screw holes corresponding to each other.

[0012] In one embodiment, the screw hole is a countersunk hole.

[0013] The utility model is implemented with a flat grinding decomposition polishing disc and polishing structure capable of rapid disc replacement. By installing multiple fan-shaped discs on the grinding disc of the original flat grinding machine and installing grinding skin on each fan-shaped disc to form a new polishing disc, the weight of a single fan-shaped disc is reduced during disc replacement and logistics processing, thereby reducing the difficulty of disc replacement operation. The disassembly and assembly of the grinding disc is replaced by the disassembly and assembly of the fan-shaped disc. Since a single fan-shaped disc has a small weight, the operation risk is reduced, the operation safety is improved, and there is no need for a forklift, thereby shortening the disc replacement time. When the fan-shaped disc is set, the grinding skin is decomposed. When the grinding skin is damaged, it is only necessary to replace the fan-shaped disc of the area with a grinding skin of corresponding thickness, thereby reducing grinding skin waste and reducing the use cost of the flat grinding machine.

[0019] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0020] In view of the problems existing in traditional flat grinders, such as difficulty in changing discs, long disc changing time, potential safety hazards, serious waste of grinding skin, and impact on machine utilization rate, the utility model installs a flat grinding decomposition polishing disc composed of multiple fan-shaped discs on the grinding disc of the original flat grinder. When changing discs, only the fan-shaped disc needs to be replaced, which reduces the difficulty of disc changing and shortens the disc changing time. Compared with grinding discs, the fan-shaped disc is lighter and can reduce the risk of safety accidents caused by falling. The grinding skin is divided into multiple pieces. If the local grinding skin is damaged during the processing, it only needs to replace the fan-shaped disc in that area with the grinding skin of corresponding thickness, thereby improving the utilization rate of grinding skin and saving the amount of auxiliary materials.

[0021] For details, please combine Figure 1-3The flat grinding decomposition polishing disc of this embodiment is used for being detachably mounted on the grinding disc of a flat grinder. It utilizes the existing flat grinder machine, is directly mounted on the grinding disc of the flat grinder and is used as the polishing operation part of the flat grinder. Only a small amount of improvement is required to the original flat grinder machine, thereby reducing the modification cost of the flat grinder. The flat grinding decomposition polishing disc 10 includes at least two fan-shaped discs 100 distributed along an annular path and connected in sequence. Each fan-shaped disc 100 is spliced ​​together to form an annular disc-shaped structure. That is to say, one side of each fan-shaped disc 100 close to the center of the annular disc-shaped structure and one side away from the center of the annular disc-shaped structure are both arc surfaces. Preferably, the flat grinding decomposition polishing disc 10 includes at least two fan-shaped discs 100 of equal size. Each fan-shaped platter 100 includes a first surface adjacent to the flat grinder grinding disc, a second surface facing away from the flat grinder grinding disc, a first side adjacent to the fan-shaped platter 100 on one side, and a second side adjacent to the fan-shaped platter 100 on the other side. The second surface of the fan-shaped platter 100 is attached with a microdermabrasion 200, and the shape of the microdermabrasion 200 is adapted to the shape of the second surface. The first side of each fan-shaped platter 100 is provided with at least one protrusion 110, and the second side of each fan-shaped platter 100 is provided with at least one recess 120 which corresponds one-to-one with the protrusion 110 of the adjacent fan-shaped platter 100. In this embodiment, when the flat grinding decomposition polishing disc 10 includes two fan-shaped platters 100 of equal size, the central angles corresponding to the two fan-shaped platters 100 are 180° respectively, and the first side of the first fan-shaped platter 100 cooperates with the second side of the second fan-shaped platter 100, and the second side of the first fan-shaped platter 100 cooperates with the first side of the second fan-shaped platter 100, and through the cooperation of the protrusion 110 and the recess 120, precise positioning of the fan-shaped platter 100 during installation is achieved. When the number of fan-shaped platter 100 included in the flat grinding and decomposition polishing disc 10 is greater than two, for example, when the number of fan-shaped platter 100 is N (N is an integer greater than 2), the second side of the first fan-shaped platter 100 cooperates with the first side of the second fan-shaped platter 100, the first side of the third fan-shaped platter 100 cooperates with the second side of the second fan-shaped platter 100...the second side of the Nth fan-shaped platter 100 cooperates with the first side of the first fan-shaped platter 100, thereby forming an annular disc structure, and the central angle corresponding to each fan-shaped platter 100 is 360° / N.

[0022] In this embodiment, by providing protrusions 110 and recesses 120 on both sides of the fan-shaped disc 100, not only can the positioning of the fan-shaped disc 100 be achieved during installation, but also when the flat grinding decomposition polishing disc 10 rotates and polishes the product, all the fan-shaped discs 100 are pulled outward by the centrifugal force, and the protrusions 110 can enhance the bonding force between adjacent fan-shaped discs 100 and reduce the load on the connection between the fan-shaped disc 100 and the grinding disc. The cooperation between the protrusions 110 and the recesses 120 between adjacent fan-shaped discs 100 can better adapt to the disc-shaped structure of the grinding disc, provide a more stable splicing and fixing effect, and make the polishing operation of the product more stable and reliable.

[0023] In this embodiment, the number of the fan-shaped platters 100 is 8, and the shapes and sizes of the 8 fan-shaped platters 100 are the same. Furthermore, the fan-shaped platters 100 are made of aluminum, and the weight of a single fan-shaped platter 100 is less than or equal to 2.3 kg. In this way, employees can easily operate during the plate changing, logistics processing and transportation process without the assistance of a forklift, which greatly reduces the operational danger and the difficulty of plate changing, and saves auxiliary resources.

[0024] Furthermore, in this embodiment, the microdermabrasion 200 is attached to the second surface. Specifically, before the fan-shaped platter 100 is installed, the microdermabrasion 200 needs to be pre-processed into a shape matching the fan-shaped platter 100, and when the microdermabrasion 200 is attached, it is directly attached to the second surface of the fan-shaped platter 100, without the need for subsequent cutting of the shape, thereby improving the utilization rate of the microdermabrasion 200 and the efficiency of attaching the microdermabrasion 200.

[0025] In order to improve the firmness of the fit between adjacent sector-shaped platters 100, the ratio of the sum of the projected lengths of each protrusion 110 on the first side of the sector-shaped platter 100 to the width of the first side of the sector-shaped platter 100 is greater than or equal to 1 / 3, the protrusion 110 is a rectangular sheet structure, each corner of the protrusion 110 is an arc angle, and the inner contour of the recess 120 is adapted to the outer contour of the protrusion 110. Preferably, in this embodiment, a protrusion 110 is provided in the middle of the first side of the sector-shaped protrusion 110, and a recess 120 is provided in the middle of the second side of the sector-shaped protrusion 110, so as to reduce the difficulty of processing the sector-shaped protrusion 110.

[0026] During the splicing and installation process of the fan-shaped platter 100, each grinding skin 200 is firstly correspondingly attached to the second surface of the corresponding fan-shaped platter 100, so that the first surface of the single fan-shaped platter 100 fits the polishing surface of the grinding wheel of the flat grinder, and then the fan-shaped platter 100 is fixed on the grinding wheel of the flat grinder. When installing the second fan-shaped platter 100, the second fan-shaped platter 100 can be pre-positioned by means of the protrusion 110 on the second fan-shaped platter 100 and the concave-convex cooperation of the concave position 120 on the first fan-shaped platter 100, or by means of the concave-convex cooperation of the concave position 120 on the second fan-shaped platter 100 and the protrusion 110 on the first fan-shaped platter 100. On the one hand, it can avoid the movement of the second fan-shaped platter 100 when it is fixed, thereby causing the occurrence of installation misalignment problems. On the other hand, it can achieve rapid positioning of the second fan-shaped platter 100 to avoid position deviation when the second fan-shaped platter 100 is positioned. Install each sector-shaped platter 100 in sequence according to the installation method of the second sector-shaped platter 100 until the last sector-shaped platter 100 is assembled with the first sector-shaped platter 100 and fixed on the polishing surface of the grinding disc, thus completing the installation of the flat grinding decomposition polishing disc 10 on the grinding disc.

[0027] Please combine Figure 4 and Figure 5 The utility model also discloses a polishing structure, including a grinding disc fixed on a flat grinder, the grinding disc including a polishing surface for polishing a product surface, and the above-mentioned flat grinding decomposition polishing disc 10 is detachably mounted on the polishing surface. Furthermore, a plurality of screw holes 130 penetrating the first surface and the second surface are provided on the fan-shaped platter 100, a plurality of mounting holes 201 corresponding to each of the screw holes 130 are provided on the grinding disc, and the fan-shaped platter 100 is fixedly connected to the grinding disc by screws 202 penetrating the mounting holes 201 and the screw holes 130 in a one-to-one correspondence. In other words, each fan-shaped platter 100 is fixed to the grinding disc of the flat grinder by screws 202 for easy disassembly. Preferably, the flat grinding decomposition polishing disc 10 includes 8 fan-shaped platter 100 of equal size, and each fan-shaped platter 100 has 4 screw holes 130. The screw hole 130 is a countersunk hole, that is, the screw hole 130 is concave and sunken. In this way, after the screw 202 is fixed to the grinding disc, it can be ensured that the nut of the screw 202 will not exceed the second side of the fan-shaped platter 100, preventing the screw 202 from interfering with the polishing operation.

[0028] In this embodiment, the grinding disc is a cast iron disc of a flat grinder, which is a cast iron polishing disc used on the original machine in the factory. By opening 32 mounting holes 201 on the polishing surface of the cast iron polishing disc, corresponding to the screw holes 130 on each fan-shaped platter 100, the fan-shaped platter 100 is fixed on the cast iron disc, which can provide a stable platform for polishing. The cast iron disc (grinding disc) is fixed on the machine for a long time and no longer needs to be disassembled. When changing the disc, the employee only needs to lift the fan-shaped platter 100 with one hand to complete the disc change, which greatly improves the efficiency and safety of disc change.

[0029] The grinding disc can be a lower grinding disc fixed on the flat grinder table, or an upper grinding disc fixed on the flat grinder bracket. Figure 4 The structure of the flat grinding decomposition polishing disc 10 and the flat grinding machine upper grinding disc 20 is shown. Figure 5 The structure of the flat grinding decomposition polishing disc 10 combined with the flat grinding lower grinding disc 30 is shown. When the fan-shaped disc 100 is fixed to the upper grinding disc 20, the fan-shaped disc 100 is provided with liquid inlet holes 140 corresponding to and connected with the liquid holes 203 of the upper grinding disc 20 and the same number, and the screw holes 130 on the fan-shaped disc 100 correspond to the mounting holes 201 on the upper grinding disc 20; when the fan-shaped disc 100 is fixed to the lower grinding disc 30, the screw holes 130 on the fan-shaped disc 100 correspond to the mounting holes 201 on the lower grinding disc 30.

[0030] When installing the microdermabrasion 200, the microdermabrasion 200 is first pre-processed into a shape that matches the fan-shaped platter 100, that is, the contour shapes of the two are adapted to each other, and holes corresponding to the screw holes 130 and the liquid inlet holes 140 are opened on the microdermabrasion 200. After the microdermabrasion 200 is formed as a single piece, the side of the microdermabrasion 200 that faces away from its grinding surface is brushed with glue and directly adhered to the second side of the fan-shaped platter 100. At the same time, the holes on the microdermabrasion 200 are matched with the liquid inlet holes 140 and the screw holes 130 on the fan-shaped platter 100, and the holes of all parts are overlapped. The advantage of using a single-piece microdermabrasion 200 is that when a local microdermabrasion 200 is damaged during processing, it is only necessary to match the microdermabrasion 200 of the corresponding thickness and replace the fan-shaped platter 100 in that area, without replacing the microdermabrasion 200 of the entire disc, which improves the utilization rate of the microdermabrasion 200 and saves the amount of auxiliary materials to a certain extent.

[0031] During the installation of the grinding disc, for the upper grinding disc 20, since the original disc has a liquid hole 203, only 32 screw holes 130 need to be added to the polishing surface of the upper grinding disc 20 to provide a mounting portion for the fan-shaped platter 100. The upper grinding disc 20 is directly fixed to the cylinder bracket of the machine with screws, and it is not disassembled for long-term recycling after being fixed. For the lower grinding disc 30, 32 screw holes 130 are directly added to the original disc to provide a mounting portion for the fan-shaped platter 100. The lower grinding disc 30 is installed and supported inside the machine, and it does not need to be disassembled and moved for long-term use in the later stage.

[0032] When the platter is processed off-line, the waste grinding skin 200 of the old disc is scraped off and cleaned, and the second side of the sector-shaped platter 100 with the waste grinding skin 200 removed is brushed with glue and the grinding skin 200 is pasted, that is, the off-line pre-processing of the sector-shaped platter 100 is completed. When it is necessary to change the disc, for the new disc to be put on the machine, the four screw holes 130 of the first sector-shaped platter 100 are aligned with the mounting holes 201 of the grinding disc, and the screws 202 are passed through the screw holes 130 of the sector-shaped platter 100 and fixed to the mounting holes 201 of the grinding disc, and then the remaining sector-shaped platter 100 is installed one by one until all the sector-shaped platter 100 are fixed. For removing the old disc from the machine, when removing the fan-shaped platter 100 fixed on the upper grinding disc 20, the operator holds up one fan-shaped platter 100 with one hand, and uses the other hand to take the electric screw gun to screw out the four screws 202 from the upper grinding disc 20, and after removing the single fan-shaped platter 100, the remaining fan-shaped platter 100 is removed in sequence to complete the removal of the upper grinding disc 20. When removing the fan-shaped platter 100 fixed on the lower grinding disc 30, the screw gun can simultaneously screw out all the screws fixed on the lower grinding disc 30, and then all the fan-shaped platter 100 are removed in sequence to complete the removal of the lower grinding disc 30.

[0033] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0034] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
