Description

Technical Field

[0001] This utility model belongs to the field of 3D printing technology, and more specifically, it relates to an automatic water circulation polishing post-processing workbench for 3D printed products. Background Technology

[0002] As a core technology in the field of rapid prototyping, 3D printing technology has been widely used in many industries such as aerospace, automobile manufacturing, medical devices, and consumer goods. By depositing materials layer by layer, it can quickly realize the personalized manufacturing of complex structural parts, significantly shortening the product development cycle and reducing mold costs. However, 3D printed products often have defects such as layer lines, burrs, and step effects on their surface, which directly affect the dimensional accuracy, surface roughness, and mechanical properties of the products. Therefore, surface finishing is required through post-processing, among which grinding is one of the most commonly used methods.

[0003] Application number CN201821264617.4 discloses a water-circulating worktable for a grinding device, including a water storage box, an operating plate, a cooling mechanism, and a movable water baffle for the grinding machine. The operating plate is detachably mounted on the water storage box and has several drainage holes. The cooling mechanism and the movable water baffle are movably mounted on the operating plate. During fine carving or grinding, the tools are placed on the operating plate. The position of the cooling mechanism base and the position of the universal adjustable water spray head can be adjusted as needed to supply water through the pump body for real-time cooling of the grinding tools. The movable water baffle prevents cooling water from splashing onto the operator. Furthermore, the water-circulating worktable of the grinding device has a simple structure, reliable performance, and is convenient and practical.

[0004] Based on the above patent searches and understanding of the application of automatic water-circulation polishing post-processing in existing 3D printed products:

[0005] For 3D printed products of different sizes and shapes, it is difficult to achieve stable and accurate positioning, which makes the products prone to shaking during the polishing process, affecting the polishing accuracy and effect.

[0006] The water circulation system is poorly designed, resulting in low water resource utilization and ineffective filtration. The circulating water contains many impurities, which can easily clog nozzles and other components, affecting the normal operation and lifespan of the equipment. Utility Model Content

[0007] To address the aforementioned technical problems, this utility model provides an automatic water-circulating post-processing workbench for 3D printed products. This solves the problems of existing processing workbenches struggling to achieve stable and precise positioning for 3D printed products of different sizes and shapes, leading to product wobbling during the polishing process, affecting polishing accuracy and results, and the current water circulation system design being unreasonable, resulting in low water resource utilization and poor filtration, with many impurities in the circulating water that easily clog nozzles and other components, affecting the normal operation and service life of the equipment.

[0008] The technical solution adopted in this utility model is as follows:

[0009] An automatic water-circulating polishing post-processing workbench for 3D printed products includes a circulation seat; a processing collection platform is fixedly installed at the top center of the circulation seat, and a sedimentation tank is fixedly installed at the rear center of the circulation seat. The rear end of the processing collection platform and the front end of the sedimentation tank are connected by a pipe. A filter is installed inside the sedimentation tank, and an inlet pipe is installed at the bottom left side of the filter. The other end of the inlet pipe is installed at the lower left side of the sedimentation tank, and a valve is installed at the front right side of the filter.

[0010] According to one embodiment of the present invention, the other end of the valve is connected to a circulation pump via a pipe, and the other end of the circulation pump is connected to a nozzle via a pipe. The nozzle is located at the top center of the processing and collection platform.

[0011] According to one embodiment of the present invention, a positioning frame is fixedly installed at the top center of the processing and collection platform, and an opposing screw is rotatably connected to the inner center of the positioning frame.

[0012] According to one embodiment of the present invention: the threads on the left and right sides of the opposing screw are designed to be opposite, a platform is fixedly installed at the top center of the positioning frame, a through groove is opened at the center of the side of the platform, and the center of the opposing screw is located in the through groove of the platform.

[0013] According to one embodiment of the present invention, a clamping plate is slidably connected to the upper left and right sides of the positioning frame. The two clamping plates are symmetrically designed, and each clamping plate has a threaded hole at the lower middle position of its side. The threaded hole of the clamping plate is passed through the left and right sides of the opposing screw.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The opposing screws inside the positioning frame have reversed threads on both sides. When the opposing screws are rotated, the two clamping plates can slide left and right inside the positioning frame, thereby achieving centered clamping and positioning of 3D printed products of different sizes on the platform, ensuring that the products are stable and do not shake during the grinding process, and improving the grinding accuracy.

[0016] 2. The treatment collection platform and the sedimentation tank are connected by pipes. Wastewater and debris generated during grinding can flow into the sedimentation tank, be filtered by the filter, and then return to the treatment collection platform through the nozzles under the action of the circulation pump. This realizes the recycling of water resources and saves water resources. At the same time, the filter can effectively remove impurities in the water, reduce clogging of nozzles and pipes, and extend the service life of the equipment. Attached Figure Description

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0026] Example:

[0027] As attached Figure 1 To be continued Figure 4 As shown:

[0028] This utility model provides an automatic water circulation polishing post-processing workbench for 3D printed products, including a circulation seat 1; a processing collection platform 101 is fixedly installed at the top center of the circulation seat 1, and a sedimentation tank 102 is fixedly installed at the rear center of the circulation seat 1. The rear center of the processing collection platform 101 and the front center of the sedimentation tank 102 are connected by a pipe. A filter 103 is installed inside the sedimentation tank 102. An inlet pipe 104 is installed at the bottom left side of the filter 103. The other end of the inlet pipe 104 is installed at the lower left side of the sedimentation tank 102. A valve 105 is installed at the front right side of the filter 103. The other end of the valve 105 is connected to a circulation pump 106 through a pipe. The other end of the circulation pump 106 is connected to a nozzle 107 through a pipe. The nozzle 107 is located at the top center of the processing collection platform 101. A positioning frame 2 is fixedly installed at the top center of the processing collection platform 101. A counter-rotating screw 201 is rotatably connected to the inner center of the positioning frame 2.

[0029] The opposing screw 201 has reversed threads on both sides. A shelf 203 is fixedly installed at the top center of the positioning frame 2. A through slot is opened at the center of the side of the shelf 203, and the center of the opposing screw 201 is located in the through slot of the shelf 203. A clamping plate 202 is slidably connected to the upper left and right sides of the positioning frame 2. The two clamping plates 202 are symmetrically designed, and each clamping plate 202 has a threaded hole at the lower center of its side. The opposing screw 201 passes through the threaded hole of a clamping plate 202 at the left and right sides respectively.

[0030] When using:

[0031] First, place the 3D printed product to be polished on the platform 203. Then, rotate the opposing screw 201. Since the threads on the left and right sides of the opposing screw 201 are designed to be opposite, and the two clamping plates 202 are respectively connected to the threads on the left and right sides of the opposing screw 201, the two clamping plates 202 will slide closer to each other inside the positioning frame 2 during the rotation of the opposing screw 201, thereby clamping and fixing the product on the platform 203 in the center.

[0032] Next, the circulation pump 106 is started and the valve 105 is opened. The filtered water in the sedimentation tank 102 will be transported to the nozzle 107 through the inlet pipe 104, filter 103, valve 105 and circulation pump 106 in sequence. The nozzle 107 sprays the water onto the top center of the processing collection platform 101, which is the product polishing area.

[0033] During the product polishing process, the dust generated is suppressed by sprayed water to prevent it from spreading; the debris and wastewater generated during polishing flow onto the processing collection platform 101, and then flow into the sedimentation tank 102 through the pipe connecting the rear end of the processing collection platform 101 to the front end of the sedimentation tank 102.

[0034] Wastewater and debris entering the sedimentation tank 102 will be filtered through the inlet pipe 104 into the filter 103 after sedimentation. The filtered water will then be transported to the nozzle 107 through the above-mentioned water circulation path to achieve water recycling. The position of the inlet pipe 104 is designed to prevent debris settled at the bottom of the sedimentation tank 102 from entering the inlet pipe 104.

[0035] After polishing is complete, turn off the circulation pump 106 and valve 105, rotate the opposing screw 201 in the opposite direction to move the two clamps 202 away from each other, loosen the clamping on the product, and then remove the polished product.

[0036] Although this application has been described with reference to the foregoing embodiments, those skilled in the art will understand that various changes can be made without departing from the spirit and scope of this application as defined by the appended claims. While this specification contains details of many specific implementations, these should not be construed as limiting the scope of the claims, but rather as descriptions of features specific to particular embodiments. The scope of this application is defined by the appended claims and their equivalents, and is not limited to the embodiments described above.
