Description

Technical Field

[0001] The present application relates to the technical field of polishing equipment, and in particular to an efficient workpiece brushing and polishing device and a polishing liquid filtering method. Background Art

[0002] Workpiece polishing is a surface treatment process that aims to improve the surface quality and appearance of the workpiece. It removes scratches, oxide layers, rust and other defects on the surface of the workpiece to make the surface smoother and flatter, achieving a mirror effect. It enhances the beauty of the workpiece and gives it a better visual effect.

[0003] Nowadays, the polishing brush device used for polishing usually uses tools such as polishing wheels and sandpaper, and cooperates with polishing liquid to repeatedly rub against the surface of the workpiece under a certain pressure to remove the microscopic unevenness of the surface.

In order to reduce costs, it is usually necessary to filter the polishing liquid and reuse it. However, traditional polishing machines usually require additional filtering equipment to filter the polishing liquid, and then pump the filtered polishing liquid back to the polishing brush device for reuse.

[0044] In addition, the technical features involved in the different embodiments of the present invention described above can be combined with each other as long as they do not conflict with each other.

[0045] The present invention provides Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a highly efficient workpiece brushing and polishing device is used to grind and polish the surface of the workpiece, remove scratches, oxide layers, rust and other defects on the surface of the workpiece, make the surface smoother and flatter, and achieve a mirror effect. Enhance the aesthetics of the workpiece and give it a better visual effect. Its main structure includes: a machine 1, a polishing assembly 2 and a polishing liquid delivery assembly 3; the machine 1 is used to fix the polishing assembly 2 and the polishing liquid delivery assembly 3. The polishing assembly 2 includes a workpiece fixing disk 21 and a polishing disk 22, and the workpiece fixing disk 21 and the polishing disk 22 are both arranged on the machine 1. The polishing disk 22 is stacked on the workpiece fixing disk 21, and the two rotate in opposite directions to make the grinding and polishing more efficient. The polishing disk 22 is used to polish the workpiece on the workpiece fixing disk 21; the polishing liquid delivery assembly 3 is used to deliver polishing liquid to the workpiece fixing disk 21 and the polishing disk 22, and the addition of polishing liquid makes the grinding and polishing effect better;

[0046] Among them, the workpiece fixing plate 21 is provided with a polishing area 211 and a deposition area 212. The deposition area 212 is arranged around the polishing area 211. The deposition area 212 is used to precipitate impurities in the polishing liquid. The polishing area 211 is used to fix the workpiece to be polished, and the workpiece is polished in the polishing area 211. A first enclosure 213 is arranged on the periphery of the deposition area 212. The first enclosure 213 is used to prevent the polishing liquid from being thrown out and prevent the polishing liquid from splashing out when the workpiece is polished. At least one through-hole 214 is opened between the deposition area 212 and the polishing area 211. The liquid outlet 214 is used to guide the polishing liquid after deposition. The polishing liquid after polishing flows from the polishing area 211 to the deposition area 212 through the liquid outlet 214. Then the polishing liquid and impurities are separated by layers in the deposition area 212 by centrifugal force. In this way, the effect of filtering and purifying the polishing liquid is achieved.

[0047] It should be noted that traditional polishing machines usually require additional filtering equipment to filter the polishing liquid, and then pump the filtered polishing liquid back to the polishing brush device for reuse. This structural design requires the addition of filtering equipment, which increases the equipment cost; on the other hand, the additional equipment will inevitably increase the working energy consumption of the device. This is not conducive to energy conservation and emission reduction.

[0048] The present invention performs polishing operation on the workpiece by means of the rotating workpiece fixing disk 21, and separates the polishing liquid and impurities into layers by means of the rotating centrifugal force of the workpiece fixing disk 21. The polishing liquid is placed on the inner side of the layers, and the impurities are placed on the outer side of the layers, and then the filtered polishing liquid is led out through the liquid outlet 214 provided between the deposition area 212 and the polishing area 211. In this way, the technical effect of filtering and recovering the polishing liquid is achieved, which effectively improves the filtering effect of the polishing liquid and facilitates the removal of impurities. In some embodiments, an annular groove is provided in the deposition area 212, and the annular groove extends around the extension direction of the deposition area 212, and the annular groove is provided on the periphery of the deposition area 212, and the annular groove is used to deposit impurities in the polishing liquid, so that the impurities in the polishing liquid can be better formed in the annular groove. It is also more convenient for the staff to remove the formed impurity blocks.

[0049] Further, such as Figure 5 and Figure 6 As shown, a second enclosure 215 is provided between the deposition area 212 and the polishing area 211 , and a plurality of through holes 2151 are evenly formed at the bottom of the second enclosure 215 , and the through holes 2151 are used to guide the polishing liquid.

[0050] It should be noted that the second enclosure 215 can prevent the polishing liquid sprayed in the polishing area 211 from directly splashing to the deposition area 212. Since the splashed polishing liquid carries kinetic energy, when the polishing liquid splashes to the polishing liquid in the deposition area 212 that is separating impurities, it will interfere with the polishing liquid that is separating impurities, affecting the impurity separation effect and efficiency of the polishing liquid. Therefore, it is necessary to set the second enclosure 215 between the deposition area 212 and the polishing area 211, and the polishing liquid in the polishing area 211 slowly flows to the deposition area 212 through the through hole 2151 at the bottom of the second enclosure 215, and then the impurities are separated in the deposition area 212.

[0051] Further, such as Figure 6 and Figure 7 As shown, a plurality of through-holes 214 are formed on the workpiece fixing plate 21 , and the plurality of liquid outlet holes 214 are evenly arranged between the deposition area 212 and the polishing area 211 .

[0052] It should be noted that while the rotating workpiece fixing disk 21 is polishing the workpiece, centrifugal force will be generated on the polishing liquid on the workpiece fixing disk 21. The polishing liquid and impurities are separated by layers through centrifugal force. Since the polishing liquid is light in weight, the polishing liquid is on the inner side of the deposition area 212. The impurities are heavier and are on the outer side of the layers. Over time, the impurities in the polishing liquid will be deposited and agglomerated on the outer side of the deposition area 212. The polishing liquid can flow out of the liquid outlet 214 between the deposition area 212 and the polishing area 211. In this way, the technical effect of filtering and recovering the polishing liquid is achieved, which effectively improves the filtering effect of the polishing liquid and facilitates the removal of impurities.

[0053] Further, such as Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, an annular collecting groove 23 is disposed on the machine 1 , and the opening of the annular collecting groove 23 is disposed corresponding to a plurality of liquid outlet holes 214 .

[0054] It should be noted that the polishing liquid flowing out of the liquid outlet 214 will be collected by the annular collecting groove 23, and drained to the liquid storage tank 31 through the collecting pipe 32 at the bottom of the annular collecting groove 23, and can be deposited again in the liquid storage tank 31, so that the polishing liquid can be further purified.

[0055] Further, such as Figure 5As shown, one end of the polishing disc 22 facing the workpiece fixing disc 21 is detachably connected with a plurality of polishing heads 221, and the polishing heads 221 are evenly arranged around the rotation axis of the polishing disc 22; the polishing heads 221 are arranged correspondingly to the workpiece fixing bracket 2111, so that even if the workpiece fixing disc 21 and the polishing disc 22 rotate in opposite directions, the polishing heads 221 and the workpiece fixing bracket 2111 can be ensured to be on the same rotation movement track, so that the polishing heads 221 can grind and polish the workpiece to be polished on the workpiece fixing bracket 2111 at all times.

[0056] like Figure 4 and Figure 5 As shown, a liquid accumulating groove 222 is provided at one end of the polishing disc 22 facing away from the workpiece fixing disc 21, and a plurality of drip holes 223 are provided through the liquid accumulating groove 222, and the plurality of drip holes 223 are respectively arranged corresponding to the plurality of polishing heads 221. The purified polishing liquid in the liquid storage tank 31 is conveyed to the liquid accumulating groove 222 through the liquid outlet pipe 33, and then drips onto the polishing head 221 through the drip holes 223 on the liquid accumulating groove 222. The polishing head 221 can always be involved in the polishing liquid when polishing the workpiece, thereby improving the polishing effect.

[0057] Further, such as Figure 3 , Figure 4 As shown, the polishing liquid delivery assembly 3 includes: a liquid storage tank 31, a collecting pipe 32 and a liquid outlet pipe 33, the liquid storage tank 31 is arranged on the machine 1; the two ends of the collecting pipe 32 are respectively connected to the annular collecting tank 23 and the liquid storage tank 31; one end of the liquid outlet pipe 33 is connected to the annular collecting tank 23, and the other end is arranged at the open upper end of the liquid accumulation tank 222, and a water pump is arranged on the liquid outlet pipe 33, and the water pump is used to pump the polishing liquid to the liquid accumulation tank 222.

[0058] Further, such as Figure 2 , Figure 3 As shown, the polishing assembly 2 further includes: a first driving member 24 and a second driving member 25, wherein the first driving member 24 is disposed on the machine table 1 and is used to rotate the workpiece fixing disk 21; the second driving member 25 is disposed on the machine table 1 and is used to rotate the polishing disk 22. The workpiece fixing disk 21 and the polishing disk 22 are rotated in opposite directions, so that the workpiece can obtain a better grinding and polishing effect. In some embodiments, the workpiece fixing disk 21 and the polishing disk 22 have the same rotation axis.

[0059] Further, such as Figure 4 , Figure 5 and Figure 6As shown, a plurality of workpiece fixing brackets 2111 are movably connected to the polishing area 211, and a movable gear 2112 is provided on the workpiece fixing bracket 2111. The plurality of workpiece fixing brackets 2111 are arranged around the axis of the workpiece fixing disk 21, and the machine table 1 is provided with a fixed gear 2113, the axis of the fixed gear 2113 is the same as the axis of the workpiece fixing disk 21, and a plurality of movable gears 2112 are meshed with the fixed gear 2113, and the plurality of movable gears 2112 and the fixed gear 2113 form a planetary gear structure.

[0060] Further, such as Figure 2 , Figure 3 , Figure 4 As shown, a lifting assembly 11 is provided on the machine 1, and the lifting assembly 11 is used to adjust the distance between the polishing disc 22 and the workpiece fixing disc 21, and the second driving member 25 is provided on the lifting assembly 11. The distance between the polishing disc 22 and the workpiece fixing disc 21 is adjusted by the lifting assembly 11. When it is necessary to take or place the workpiece on the workpiece fixing bracket 2111 or replace the polishing head 221, the polishing disc 22 needs to be separated from the workpiece fixing disc 21. Sufficient space is freed up for taking or placing the workpiece or replacing the polishing head 221.

[0061] The second aspect of the present application provides a polishing liquid filtering method for an efficient workpiece brush polishing device based on any one of the first aspects, and the polishing liquid filtering method comprises the following steps:

[0062] Step 1: rotating the polishing disc 22 by the first driving member 24;

[0063] Step 2, the polishing liquid is thrown to the deposition area 212 by the rotating polishing disc 22;

[0064] Step 3: Under the action of centrifugal force, impurities in the polishing liquid are deposited on the outside of the deposition area 212, and the filtered polishing liquid flows to the annular collection tank 23 through the liquid outlet 214;

[0065] Step 4, transporting the filtered polishing liquid to the liquid storage tank 31 through the annular collecting tank 23;

[0066] Step five: transport the polishing liquid in the liquid storage tank 31 to the liquid storage tank 222 on the polishing plate 22 through a water pump, so that the polishing liquid drips onto the polishing head 221 .
