Description

Technical Field

[0001] This utility model relates to the field of automotive interior parts processing technology, specifically a burr removal device for automotive plastic interior parts. Background Technology

[0002] Automotive interiors mainly refer to automotive products used for interior modifications of cars, covering all aspects of the car's interior, such as steering wheel covers, car seat cushions, car floor mats, car perfumes, car pendants, interior decorations, storage boxes, etc. Automotive interior parts, such as plastic products like gear shift covers, are generally injection molded. Products produced in this way usually have burrs, which need to be cleaned off with tools.

[0003] Authorized publication number CN217194438U discloses a deburring device for automotive plastic interior parts. This device mainly utilizes a multi-directional deburring mechanism to simultaneously grind and deburr multiple areas of the plastic interior parts, offering convenient operation and saving time. Furthermore, it employs multiple sliding fixed discs for pre-loading interior parts, allowing the next part to immediately enter the operating position for deburring after the previous one has been deburred, reducing waiting time and improving efficiency. Additionally, a closed processing hood prevents the removed burrs from falling into the conveyor trough, reducing contamination of the work surface. However, in actual use, the device still has the following drawbacks:

[0004] The aforementioned patent mainly uses a multi-directional deburring mechanism to simultaneously grind and deburr plastic interior parts from multiple angles. However, when grinding interior parts from multiple angles, the grinding heads are prone to collisions when multiple grinding mechanisms are used, which hinders the simultaneous grinding of small interior parts from multiple angles. This also increases the cost of the structure and the consumption of driving force. Furthermore, the angle of the fixed interior parts is difficult to adjust, and the fixed position of the interior parts usually needs to be adjusted manually, which greatly increases the limitations and inconvenience of interior part deburring. Moreover, as the angle of the interior parts is difficult to adjust, the rinsing of the interior part surface is prone to unevenness, affecting the processing accuracy of the interior parts and reducing the efficiency of interior part deburring.

[0025] A water tank 15 is located in the middle of the interior of the mounting base 1. A drain valve is located at the bottom of one side of the water tank 15 to facilitate the drainage and replacement of the water that has been recycled multiple times. A water pump 14 is located on one side of the top of the water tank 15, and a suction pipe extending to the bottom of the water tank 15 is located on one side of the water pump 14. The output end of the water pump 14 is connected to a guide pipe 7. A through hole is opened in the middle of the interior of the rotating base 6. The guide pipe 7 passes through the inside of the through hole and is equipped with a nozzle. Guide grooves 12 are located on both sides of the interior of the rotating base 6, and a filter screen groove 1 is located at the top of the inner side of the guide groove 12. 1. The bottom of the two sets of guide channels 12 is connected to the drain pipe 13. The top of the water tank 15 is provided with an opening. The two sets of drain pipes 13 are perpendicular to the opening, so that the drained water can flow back into the water tank 15 through the drain pipe 13. The two sets of mounting bases 1 are respectively provided with a second motor 18 and a second annular slide 19 on both sides of the top of the interior. The two sets of second annular slides 19 are respectively installed on the outside of the second motor 18. The bottom of the interior of the two sets of rotating bases 6 is provided with an inclined plate, and the inclined plate is connected to the drain pipe 13 to facilitate the circulation and spraying of the drained water.

[0026] The inner sides of the two sets of second annular slide grooves 19 are respectively provided with four sets of slidingly engaged second guide blocks, and the top of the second guide blocks is connected to an external gear ring 20. The output ends of the two sets of second motors 18 are respectively provided with second gears 17 that mesh with the external gear ring 20. The top of the two sets of external gear rings 20 is respectively provided with four sets of mounting blocks 21. The top of the four sets of mounting blocks 21 on the same side is provided with mounting rings 10. The inner sides of the two sets of mounting rings 10 are symmetrically provided with positioning screws 16. The side of the two sets of positioning screws 16 on the same side that are close to each other is provided with a positioning plate, and the outer side of the positioning plate is provided with anti-slip texture to increase the clamping and fixing effect of automotive plastic interior parts.

[0027] The deburring mechanism 8 includes an electric push rod, a lifting frame, an output motor, and a grinding disc. The top of the mounting frame 9 is equipped with an electric push rod, and the output end of the electric push rod is equipped with a lifting frame. The inner side of the lifting frame is equipped with an output motor and a grinding disc. The grinding disc facilitates the deburring work through the adjustment and drive of the push rod structure and the output motor.

[0028] Example 1, such as Figure 1-3 As shown, the two sets of filter screen troughs 11 include placement troughs and filter screen plates. The placement troughs are fixedly installed on the top of the inner side of the guide trough 12, and the filter screen plates are placed inside the placement troughs. The separation of the placement troughs and the filter screen plates makes it easy to remove the filter screen plates from the placement troughs, so as to clean the powder separated by the filter screen plates and increase the convenience of disassembly and maintenance of the structure.

[0029] Example 2, as Figure 1-2 As shown, the outer gear ring 20 and the mounting ring 10 are connected to each other and rotate synchronously. The deburring mechanism 8 is opposite to the vertical plane of any set of mounting rings 10. By adjusting the rotation of the rotating seat 6, it is easy to align the rotating structure of one set of outer gear rings 20 and mounting rings 10 with the vertical plane of the deburring mechanism 8. Thus, the deburring mechanism 8 and the rotating mounting rings 10 are used to perform all-round deburring of the interior trim installed inside the mounting rings 10. At this time, the interior trim inside the other set of mounting rings 10 can be removed and replaced, so as to orderly install, remove and polish the interior trim, and improve the continuity and efficiency of the interior trim deburring work.

[0030] Working principle: This device is used in deburring of automotive plastic interior parts;

[0031] When deburring automotive plastic interior trim parts, the trim parts are placed inside a set of mounting rings 10 and fixed using positioning screws 16. Then, the first motor 2 drives the first gear 3 to mesh with the internal gear ring 4, causing the internal gear ring 4 to drive the rotating seat 6 to rotate as a whole under the structural cooperation of the first annular slide groove 5. This allows the trim parts placed inside the mounting rings 10 to be perpendicular to the deburring mechanism 8, and the deburring mechanism 8 is used to adjust the structure for deburring. During this process, the trim parts are loaded and unloaded inside another set of mounting rings 10, so that one set of trim parts is processed while another set is loaded and unloaded, allowing for continuous and orderly deburring of multiple trim parts, reducing the waiting time for trim part processing and loading / unloading operations. While the trim parts are being deburred, the second motor 18 is started... The drive mechanism 17 engages with the external gear ring 20, causing the external gear ring 20 to rotate under the guidance of the second annular groove 19. Simultaneously, it drives the mounting block 21 and mounting ring 10 to rotate as a whole, thereby adjusting the angle of the interior trim. This allows the grinding structure of the deburring mechanism 8 to contact the interior trim at different angles for deburring. The external gear ring 20 continuously rotates the interior trim, causing the grinding head to evenly grind the circumferential surface of the interior trim, facilitating efficient grinding of cylindrical interior trim. At the same time, the water pump 14 is activated to extract water from the water tank 15 and guide it through the liquid guide pipe 7 to spray it from the nozzle, rinsing the grinding head of the deburring mechanism 8 and the surface of the interior trim. The rotation of the mounting ring 10 also ensures that different surfaces of the interior trim are rinsed, improving the comprehensiveness of the rinsing and increasing the accuracy and efficiency of deburring.
