Description

Technical Field

[0001] This utility model relates to the field of automotive interior parts polishing technology, specifically to an automotive interior parts polishing device that prevents dust from flying. Background Technology

[0002] In the automotive interior parts manufacturing industry, interior parts are mostly made of plastic and manufactured through injection molding. Surface defects such as burrs and flash generated during the molding process need to be eliminated through grinding to ensure the surface quality of the product. Among these, grinding the inner walls of the mounting holes for air conditioning trim panels is a key process to ensure the assembly accuracy and functional requirements of the parts, and its processing quality directly affects the reliability of subsequent installation of components such as air vents.

[0003] Chinese patent publication number CN217619646U discloses a polishing device for automotive interior parts, including a base, a base frame, a motor frame, a drive motor, and a polishing column. By placing the trim panel on the base, aligning the mounting holes on the trim panel with the through holes on the base, and moving the motor frame downwards so that the lower end of the cover abuts against the surface of the trim panel, the polishing column extends into the mounting holes. By turning on the drive motor, the polishing column rotates within the mounting holes to polish and remove burrs from the inner wall. During the polishing process, the cover can prevent dust from flying out.

[0004] The aforementioned patent document describes a method of using a cover to shield the dust generated during grinding, preventing air pollution between factories. However, this technical solution does not consider that dust can adhere to the inner wall of the cover. Dust accumulation on the inner wall of the cover may affect the rotation of the grinding column and the grinding effect. Furthermore, the adhered dust may re-adhere to the workpiece surface or the grinding column during the grinding process, leading to uneven grinding or reduced efficiency. Utility Model Content

[0005] To address the aforementioned issues, a grinding device for automotive interior parts that prevents dust from flying is provided. By incorporating a scraper for cleaning the inner wall of a protective cover and a rotary drive component for driving the scraper to rotate along the inner wall of the protective cover, the technical problem that dust accumulation on the inner wall of the protective cover may affect the rotation of the grinding column and the grinding effect is solved.

[0006] To address the problems of existing technologies, this utility model provides a sanding device for automotive interior parts that prevents dust from flying. The device includes a sanding table, a support frame on one side of the sanding table, a base plate movably disposed within the support frame, a horizontal drive component on the support frame for driving the base plate to move along the sanding table, a lead screw slide on the top of the base plate, a moving plate at the working end of the lead screw slide, a first motor on the top of the moving plate, a rotating shaft at the output end of the first motor, a sanding column at the bottom of the rotating shaft, a protective cover movably disposed at the bottom of the base plate, a vertical drive component on the base plate for driving the protective cover to move, a cleaning assembly on the inner wall of the protective cover, the cleaning assembly including a scraper for cleaning the inner wall of the protective cover and a rotary drive component for driving the scraper to rotate along the inner wall of the protective cover, and a clamping assembly for fixing the automotive interior parts on the sanding table.

[0008] Preferably, the vertical drive component includes a side plate; the side plate is disposed on one side of the base plate, a linear driver is disposed on the top of the side plate, a connecting plate is disposed at the working end of the linear driver, and one side of the connecting plate is connected to the protective cover.

[0009] Preferably, the clamping assembly includes a fixing block; two fixing blocks are provided and symmetrically arranged on the top of the grinding table. A second threaded rod is internally threaded to the fixing block. A clamping plate is provided at one end of the second threaded rod, and a knob is provided at the other end of the second threaded rod. Movable rods are movably arranged on both sides of the second threaded rod on the fixing block. One end of the movable rod is connected to one side of the clamping plate, and a limit block is provided at the other end of the movable rod.

[0010] Preferably, the grinding table has a through hole, and a collection box is provided at the bottom of the through hole.

[0023] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0024] See Figures 1 to 6 As shown, this utility model provides a sanding device for automotive interior parts to prevent dust from flying. It includes a sanding table 1, a support frame 2 on one side of the sanding table 1, a base plate 3 movably disposed inside the support frame 2, a horizontal drive component for driving the base plate 3 to move along the sanding table 1 on the support frame 2, a lead screw slide 4 on the top of the base plate 3, a moving plate 5 at the working end of the lead screw slide 4, a first motor 6 on the top of the moving plate 5, a rotating shaft 7 at the output end of the first motor 6, a sanding column 8 at the bottom of the rotating shaft 7, a protective cover 9 movably disposed at the bottom of the base plate 3, a vertical drive component for driving the protective cover 9 to move on the base plate 3, a cleaning component 10 on the inner wall of the protective cover 9, the cleaning component 10 including a scraper 101 for cleaning the inner wall of the protective cover 9 and a rotary drive component for driving the scraper 101 to rotate along the inner wall of the protective cover 9, and a clamping component 11 for fixing the automotive interior parts on the sanding table 1.

[0025] The automotive interior parts to be sanded are placed on the sanding table 1 and, after being positioned, are secured by the clamping assembly 11 to ensure they do not move during sanding. The horizontal drive component moves the base plate 3 along the sanding table 1, adjusting the horizontal position of the sanding column 8 so that it is aligned with the area to be sanded. The vertical position of the moving plate 5 is adjusted by the lead screw slide 4, bringing the sanding column 8 into contact with the surface of the automotive interior parts. The first motor 6 is started, driving the rotating shaft 7 and the sanding column 8 to rotate, initiating the sanding operation. During sanding, the vertical drive component is activated, lowering the protective cover 9 to cover the area around the sanding column 8, effectively preventing dust from flying. The sanding dust is confined within the protective cover 9, reducing environmental pollution and harm to operators. After sanding, the rotary drive component is activated, driving the scraper 101 to rotate along the inner wall of the protective cover 9 to clean the dust on the inner wall, preventing dust accumulation from affecting subsequent sanding results.

[0026] See Figures 1 to 5 As shown, the rotary drive component includes a rotating ring 102, a first gear 103, and a mounting block 104. The rotating ring 102 is rotatably mounted on the inner wall of the protective cover 9, and the bottom of the rotating ring 102 is connected to the top of the scraper 101. The first gear 103 is located on the top of the rotating ring 102. The mounting block 104 is located on one side of the protective cover 9, and a third motor 105 is located at the bottom of the mounting block 104. A second gear 106 is located at the output end of the third motor 105, and the second gear 106 meshes with the first gear 103.

[0027] When it is necessary to clean the inner wall of the protective cover 9, the third motor 105 is started. The output end of the third motor 105 drives the second gear 106 to rotate. Since the second gear 106 meshes with the first gear 103, the rotation of the second gear 106 will drive the first gear 103 and the rotating ring 102 to rotate together. The rotation of the rotating ring 102 will drive the scraper 101 to rotate along the inner wall of the protective cover 9. Since the scraper 101 is in close contact with the inner wall of the protective cover 9, it effectively scrapes away the dust and debris attached to the inner wall of the protective cover 9, preventing dust accumulation from affecting the subsequent polishing effect.

[0028] See Figure 4 As shown, the vertical drive component includes a side plate 91; the side plate 91 is disposed on one side of the base plate 3, and a linear driver 92 is disposed on the top of the side plate 91. A connecting plate 93 is disposed at the working end of the linear driver 92, and one side of the connecting plate 93 is connected to the protective cover 9.

[0029] When the position of the protective cover 9 needs to be adjusted, the linear actuator 92 is activated. The linear actuator 92 is a cylinder. The linear actuator 92 drives the connecting plate 93 to move. The movement of the connecting plate 93 drives the protective cover 9 to move until the protective cover 9 covers the grinding column 8.

[0030] See Figure 6 As shown, the clamping assembly 11 includes a fixing block 1101; there are two fixing blocks 1101, which are symmetrically arranged on the top of the grinding table 1. The fixing block 1101 is internally threaded with a second threaded rod 1102. One end of the second threaded rod 1102 is provided with a clamping plate 1103, and the other end of the second threaded rod 1102 is provided with a knob 1104. Moving rods 1105 are movably arranged on both sides of the second threaded rod 1102 on the fixing block 1101. One end of the moving rod 1105 is connected to one side of the clamping plate 1103, and the other end of the moving rod 1105 is provided with a limit block 1106.

[0031] When it is necessary to clamp the automotive interior parts, first manually rotate the knob 1104. The rotation of the knob 1104 drives the second threaded rod 1102 to move within the fixed block 1101. The second threaded rod 1102 drives the clamping plate 1103 to move towards the automotive interior parts until the clamping plate 1103 contacts the automotive interior parts. Continue rotating the knob 1104 so that the clamping plate 1103 applies a certain pressure to the interior parts, thereby firmly clamping the automotive interior parts onto the polishing table 1, ensuring the stability of the automotive interior parts during the polishing process.

[0032] See Figure 3 As shown, a through hole is provided on the grinding table 1, and a collection box 12 is provided at the bottom of the through hole.

[0033] The collection box 12 at the bottom of the through hole facilitates the collection and treatment of debris and dust generated during the polishing process.

[0034] See Figure 1 As shown, the horizontal drive component includes a first threaded rod 21, a second motor 22, and a slide rod 23; the first threaded rod 21 is disposed inside the support frame 2, and the base plate 3 is threadedly connected to the first threaded rod 21; the second motor 22 is disposed on one side of the support frame 2, and the output end of the second motor 22 is connected to the first threaded rod 21; the slide rod 23 is disposed inside the support frame 2, and the base plate 3 is also provided with a sliding hole for the slide rod 23 to move.

[0035] When it is necessary to drive the substrate 3 to move, the second motor 22 is started, which drives the first threaded rod 21 to rotate. The rotation of the first threaded rod 21 drives the substrate 3 to move. When the substrate 3 moves, it will move on the slide rod 23 through the sliding hole on the substrate 3, thereby achieving the purpose of driving the substrate 3 to move.

[0036] See Figure 1 and Figure 2 As shown, an extension block 51 is provided on one side of the movable plate 5, and a guide rod 52 is provided on one side of the movable plate 5 located on the lead screw slide table 4. A limit plate 53 is provided at one end of the guide rod 52, and the extension block 51 is slidably disposed on the guide rod 52.

[0037] When the lead screw slide 4 drives the moving plate 5 to move, the moving plate 5 will drive the extension block 51 to move on the guide rod 52, which improves the stability of the moving plate 5.

[0038] The automotive interior trim parts to be polished are placed on the polishing table 1 and positioned. After adjustment, the knob 1104 is manually rotated, causing the second threaded rod 1102 to move within the fixed block 1101. The second threaded rod 1102 then moves the clamping plate 1103 towards the automotive interior trim parts until it contacts them. Rotating the knob 1104 further applies pressure to the clamping plate 1103, firmly holding the trim parts on the polishing table 1 and ensuring stability during polishing. The horizontal drive component moves the base plate 3 along the polishing table 1, adjusting the horizontal position of the polishing column 8 to align it with the area to be polished. The screw slide 4 adjusts the vertical position of the moving plate 5, bringing the polishing column 8 into contact with the surface of the automotive interior trim parts. The first motor 6 is started, rotating the rotating shaft 7 and the polishing column 8 to begin the polishing operation. During the polishing process, the linear actuator 92, preferably a cylinder, is activated. The linear actuator 92 drives the connecting plate 93 to move, and the movement of the connecting plate 93 drives the protective cover 9 to move until the protective cover 9 covers the area around the polishing column 8, effectively preventing dust from flying. The dust generated during polishing is confined within the protective cover 9, reducing environmental pollution and harm to operators. After polishing, when it is necessary to clean the inner wall of the protective cover 9, the third motor 105 is activated. The output end of the third motor 105 drives the second gear 106 to rotate. Since the second gear 106 meshes with the first gear 103, the rotation of the second gear 106 drives the first gear 103 and the rotating ring 102 to rotate together. The rotation of the rotating ring 102 drives the scraper 101 to rotate along the inner wall of the protective cover 9. Because the scraper 101 is in close contact with the inner wall of the protective cover 9, it effectively scrapes away the dust and debris adhering to the inner wall of the protective cover 9, preventing dust accumulation from affecting the subsequent polishing effect.

[0039] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
