Description

Technical Field

[0001] This utility model relates to the field of 3D printing technology, and in particular to a 3D printed dashboard polishing device. Background Technology

[0002] With the increasing application of dashboards in the automotive, construction machinery and other fields, dashboard polishing equipment has been established to meet the requirements of flatness and smoothness of printed dashboard surfaces. This equipment is used to carry out targeted surface treatment based on the dashboard's layer structure, material properties and complex curved surface shape, thereby reducing the surface roughness of the dashboard to a certain extent, improving its surface consistency and tactile quality, ensuring the smooth progress of subsequent assembly processes and the stability of product performance.

[0003] A search revealed Chinese patent publication number CN217552088U, which discloses a 3D printed product surface polishing device. The device includes an operating table with support plates fixedly welded to both sides of its lower surface. A moving groove is formed through the upper surface of the operating table, and two sliding rods are fixedly connected inside the moving groove. A moving mechanism is also provided inside the moving groove. This device, through the moving mechanism and angle adjustment mechanism, uses a motor and a lead screw to drive a moving box threadedly connected to the lead screw to slide within the moving groove, thereby adjusting the lateral position of the fixed table. Furthermore, through the cooperation of a second motor, an elastic telescopic rod, and a curved groove, the angle and tilt of the fixed table can be changed, facilitating polishing of different positions and angles of the finished product, improving polishing efficiency, and reducing the difficulty of polishing different positions.

[0004] The above-mentioned patent has the following shortcomings: During the polishing process, resin debris and abrasive residue generated by the device are easily mixed into the polishing liquid. These impurities make it difficult to directly recycle and reuse the polishing liquid, resulting in resource waste. At the same time, the impurities will adhere to the instrument panel surface or wear the polishing components as they circulate with the polishing liquid, which will affect the polishing accuracy and equipment lifespan to a certain extent. It also increases the labor and time costs of subsequent polishing liquid treatment.

[0005] To address this, a 3D printed dashboard polishing device is proposed. Utility Model Content

[0006] In view of this, the present invention aims to provide a 3D printed dashboard polishing device to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial alternative.

[0007] The technical solution of this utility model embodiment is implemented as follows: a 3D printed dashboard polishing device, including a support frame, and further comprising: A workbench is fixed to the top of a support frame. A housing is fixed to the top of the workbench. A drive motor is installed inside the top of the housing. A polishing wheel is installed on the rotating end of the drive motor. A liquid injection structure is installed on the top of the polishing wheel. A collection hopper is fixed to the bottom of the workbench. The top of the inside of the collection hopper is equipped with a swing structure, and the top of the swing structure is equipped with a positioning clamp. A separation structure is provided at the bottom of the collection hopper. The separation structure includes an outer cylinder fixed at the bottom of the collection hopper, a filter cylinder fixed inside the outer cylinder, a drain valve fixed at the bottom of the outer cylinder, a drain pipe fixed at the bottom of one side of the outer cylinder, and a cleaning component provided inside the filter cylinder.

[0008] In some embodiments: a first electric slide is fixed to the top of the housing, a second electric slide is fixed to the moving end of the first electric slide, a third electric slide is fixed to the moving end of the second electric slide, and the moving end of the third electric slide is connected to a drive motor; a water tank is installed on one side of the support frame, a pump body is installed at the top of the water tank, and the output end of the pump body is connected to an infusion pipe.

[0009] In some embodiments: the cleaning assembly includes a support base fixed to the bottom of the inside of the collection hopper, a cleaning motor fixed to the top of the support base, a drive shaft fixed to the end of the output shaft of the cleaning motor, and cleaning brushes fixed to both sides of the drive shaft.

[0010] In some embodiments: the drive shaft passes through the outer cylinder and extends into the interior of the filter cylinder, and the drain pipe is connected to the water tank via a pipe.

[0011] In some embodiments: the rocking structure includes a connecting frame fixed to the top of the inside of the collection hopper, a connecting plate fixed to the top of the connecting frame, a crank rotatably connected to the outer side of the top of the connecting plate, a connecting shaft fixedly connected to a positioning clamp on one side of the top of the crank, a water baffle fixed to the outer side of the bottom of the positioning clamp, and a servo motor whose output shaft end is connected to the rotating end of one of the cranks at the bottom of the connecting plate.

[0012] In some embodiments: the cranks are provided in three sets, and the three sets of cranks are arranged in a ring at equal intervals at the top of the connecting disc.

[0013] In some embodiments: the liquid injection structure includes a housing rotatably connected to the top of the polishing wheel, a fixed bracket connected to a drive motor is installed at the top of the housing, a connecting pipe connected to an infusion pipe is fixed on one side of the top of the housing, an impeller is fixed on the outside of the output shaft of the drive motor, and a liquid injection hole is opened inside the polishing wheel.

[0014] In some embodiments: the impeller is located inside the housing, the output shaft of the drive motor passes through the housing and is connected to the impeller, and a rotating structure is formed between the housing and the output shaft of the drive motor.

[0015] The present invention has the following advantages due to the adoption of the above technical solution: A 3D printed dashboard polishing device uses a filter cartridge to intercept resin debris and abrasive residue in the polishing slurry. Simultaneously, a cleaning brush driven by a cleaning motor cleans impurities from the inner wall of the filter cartridge. The filtered impurities can be periodically discharged through a drain valve, thereby realizing the polishing slurry recovery function of this device. It efficiently filters and recovers the polishing slurry, removes impurities, and keeps it in good working condition, so that it can be reused in the polishing process, reducing the consumption and waste of polishing slurry.

[0016] A 3D printed dashboard polishing device uses a servo motor to drive a crank to rotate, which in turn causes three sets of cranks to drive a positioning fixture to make a small-range eccentric circular motion. This achieves the uniform polishing function of the device, making the dashboard surface and the polishing wheel form a uniform contact, improving the polishing uniformity, and avoiding local over-polishing or unpolished situations.

[0017] A 3D printed dashboard polishing device introduces polishing slurry into the housing through a connecting pipe. At the same time, a drive motor rotates an impeller to generate continuous pressure, thereby pushing the polishing slurry into the polishing wheel through the injection hole. This realizes the polishing slurry injection function of the device, ensuring that the polishing slurry is evenly distributed inside the polishing brush, so that the polishing slurry can directly act on the polishing area and ensure the stability of the polishing effect.

[0024] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Example 1

[0025] like Figures 1 to 5 As shown, a 3D printed dashboard polishing device includes a support frame 1, and further includes: The workbench 6 is fixed to the top of the support frame 1. The top of the workbench 6 is fixed with a housing 12. The top of the housing 12 is equipped with a drive motor 10. The rotating end of the drive motor 10 is equipped with a polishing wheel 11. The top of the polishing wheel 11 is equipped with a liquid injection structure 9. The collection bucket 16 is fixed to the bottom of the workbench 6. The top of the inside of the collection bucket 16 is provided with a swing structure 7, and the top of the swing structure 7 is provided with a positioning clamp 8. The separation structure 2 is set at the bottom of the collection hopper 16. The separation structure 2 includes an outer cylinder 201 fixed at the bottom of the collection hopper 16, a filter cylinder 202 fixed inside the outer cylinder 201, a drain valve 203 fixed at the bottom of the outer cylinder 201, a drain pipe 204 fixed at the bottom of one side of the outer cylinder 201, and a cleaning component inside the filter cylinder 202.

[0026] A first electric slide 13 is fixed to the top of the housing 12. A second electric slide 14 is fixed to the moving end of the first electric slide 13. A third electric slide 15 is fixed to the moving end of the second electric slide 14. The moving end of the third electric slide 15 is connected to the drive motor 10. A water tank 3 is installed on one side of the support frame 1. A pump body 4 is installed at the top of the water tank 3. The output end of the pump body 4 is connected to an infusion pipe 5.

[0027] In this embodiment, when the device is needed, the position of the drive motor 10 is adjusted by the first electric slide 13, the second electric slide 14, and the third electric slide 15 so that the polishing wheel 11 is aligned with the instrument panel on the positioning fixture 8. At the same time, the drive motor 10 starts and drives the polishing wheel 11 to rotate, polishing the surface of the instrument panel. The pump body 4 runs synchronously to deliver the polishing liquid in the water tank 3 to the liquid injection structure 9 through the liquid delivery pipe 5. The swing structure 7 drives the positioning fixture 8 to move, balancing the polishing stress distribution. The collection bucket 16 receives the polishing liquid containing impurities that flows down during the polishing process and introduces it into the separation structure 2 for filtration, recycling, and reuse of the polishing liquid. The liquid injection structure 9 is used to directly inject the polishing liquid into the polishing wheel 11 to achieve lubrication.

[0028] like Figures 1 to 3 As shown, the cleaning assembly includes a support base 207 fixed inside the bottom of the collection hopper 16. A cleaning motor 208 is fixed to the top of the support base 207. A drive shaft 206 is fixed to the end of the output shaft of the cleaning motor 208. Cleaning brushes 205 are fixed to both sides of the drive shaft 206. The drive shaft 206 passes through the outer cylinder 201 and extends into the interior of the filter cylinder 202. The drain pipe 204 is connected to the water tank 3 through a pipe.

[0029] In this embodiment, the polishing liquid containing impurities flows from the collection hopper 16 into the filter cylinder 202 inside the outer cylinder 201. The filter cylinder 202 intercepts resin debris and abrasive residue in the polishing liquid. At the same time, the cleaning motor 208 is started to drive the transmission shaft 206 to rotate slowly, causing the cleaning brush 205 to rotate and clean the impurities on the inner wall of the filter cylinder 202, preventing the filter holes from clogging. This allows the clean polishing liquid to flow back to the water tank 3 through the drain pipe 204 for recycling. The filtered impurities can be discharged periodically through the drain valve 203, which improves the utilization rate of the polishing liquid to a certain extent and reduces resource waste. Example 2

[0030] A 3D printed dashboard polishing device, this embodiment is based on embodiment 1 with the following improvements, such as... Figures 1 to 5 As shown, the swing structure 7 includes a connecting frame 703 fixed inside the top of the collection hopper 16. A connecting plate 701 is fixed to the top of the connecting frame 703. A crank 706 is rotatably connected to the outer side of the top of the connecting plate 701. A connecting shaft 705, which is fixedly connected to the positioning clamp 8, is rotatably connected to one side of the top of the crank 706. A water baffle 702 is fixed to the outer side of the bottom of the positioning clamp 8. A servo motor 704 is installed at the bottom of the connecting plate 701. The output shaft end is connected to the rotating end of one of the cranks 706. There are three sets of cranks 706. The three sets of cranks 706 are arranged in a ring at equal intervals at the top of the connecting plate 701.

[0031] In this embodiment, the servo motor 704 is started to drive the crank 706 to rotate, while the other two sets of cranks 706 move synchronously. The crank 706 drives the positioning fixture 8 to make a small-range eccentric circular motion through the connecting shaft 705. During polishing, the polishing position is continuously adjusted to balance the polishing stress distribution, improve the smoothness and processing uniformity of the instrument panel surface, and prevent polishing liquid from splashing onto the surface of the crank 706 and the connecting shaft 705 through the water baffle 702, thus extending their service life.

[0032] like Figures 1 to 5 As shown, the liquid injection structure 9 includes a housing 901 rotatably connected to the top of the polishing wheel 11. A fixing bracket 902 connected to the drive motor 10 is installed on the top of the housing 901. A connecting pipe 903 connected to the infusion pipe 5 is fixed on one side of the top of the housing 901. An impeller 904 is fixed on the outside of the output shaft of the drive motor 10. A liquid injection hole 905 is opened inside the polishing wheel 11. The impeller 904 is located inside the housing 901. The output shaft of the drive motor 10 passes through the housing 901 and is connected to the impeller 904. A rotating structure is formed between the housing 901 and the output shaft of the drive motor 10.

[0033] In this embodiment, the polishing liquid delivered by the infusion tube 5 is introduced into the housing 901 through the connecting tube 903. At the same time, the output shaft of the drive motor 10 drives the impeller 904 to rotate and generate continuous pressure, thereby pushing the polishing liquid inside the housing 901 to be evenly injected into the polishing wheel 11 along the injection hole 905. This allows the polishing liquid to act directly on the polishing contact area, avoiding fluctuations in processing quality caused by local lack of liquid and ensuring the consistency of polishing effect.

[0034] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
