Description

Technical Field

[0001] This utility model relates to the field of auto parts processing, and in particular to a burr removal device for auto parts processing. Background Technology

[0002] Automotive parts include injection molded parts, which are automotive parts made by injecting molten plastic into a mold and then cooling and solidifying it through the injection molding process. They are widely used in the fields of interior and exterior trim, power systems, safety structures, and functional components. However, injection molded parts are prone to burrs after molding. The root cause of burr formation is that the molten plastic seeps into the mold's mating gaps under high pressure and solidifies. Among them, the skirt, as the intersection area of ​​the mold parting surface, slider, ejector pins, and other structures, is more prone to burr formation.

[0003] Chinese patent CN210232478U discloses a deburring device for processing auto parts. By adjusting the robotic arm, it can deburr auto parts from various directions, thereby improving the shortcomings of low efficiency and poor precision of manual deburring.

[0004] The above solution uses a robotic arm to control the movement of a rotating wire brush, thereby removing burrs from the surface of the part. However, when cleaning burrs on the skirt of an injection-molded part, the skirt, being a thin-walled structure extending from the edge of the injection-molded part, is prone to deformation. Furthermore, the wire brush inevitably squeezes the skirt during burr removal, leading to inward indentation of the skirt. This results in the skirt being easily deformed under pressure during burr removal from the surface of the injection-molded automotive parts. To address this issue, a burr removal device for automotive parts processing is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a burr removal device for processing auto parts, so as to solve the problem mentioned in the background art that the skirt is easily deformed by pressure when cleaning burrs on the surface of the skirt of auto parts injection molding.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3 In this utility model, a burr removal device for processing auto parts includes a top plate 1 and a bottom plate 101. A positioning plate 4 is provided on the top of the bottom plate 101. A rotating shaft 7 and a cleaning wheel 701 are provided above the positioning plate 4. The surface of the cleaning wheel 701 is an uneven diamond-patterned surface. A collection box 8 for collecting burrs after processing is provided below the positioning plate 4. A movable plate 3 is provided below the top plate 1. A cylinder 2 is provided above the top plate 1. A motor 6 is provided above the movable plate 3.

[0018] The positioning plate 4 is installed above the base plate 101 via the load-bearing column 403. A fixing groove 402 is provided on the bottom of the positioning plate 4, and a limiting block 401 is provided on the top of the positioning plate 4. The skirt 501 of the part body 5 is located inside the limiting block 401. An insert plate 801 is provided on the side of the collection box 8. The collection box 8 is installed below the positioning plate 4 by inserting the insert plate 801 into the fixing groove 402.

[0019] Example 1: Please refer to Figure 1-3 In this embodiment of the utility model, a burr removal device for processing auto parts is provided. A first guide post 301 is provided on the upper part of the movable plate 3. The upper end of the first guide post 301 passes through the top plate 1. A pressure plate 302 is provided below the movable plate 3. A through groove is provided in the middle of the pressure plate 302. The pressure plate 302 is connected to the movable plate 3 through a second guide post 303. A spring 304 is sleeved on the second guide post 303. The upper end of the second guide post 303 passes through the movable plate 3, and a stop is provided at the upper end of the second guide post 303.

[0020] The upper end of the rotating shaft 7 is connected to the bearing of the movable plate 3, and the lower end of the rotating shaft 7 passes through the closed housing 702 and is connected to the cleaning wheel 701. The closed housing 702 is installed below the movable plate 3, and the gear 703 is located inside the closed housing 702 and is installed on the rotating shaft 7.

[0021] Cylinder 2 is mounted on top plate 1, movable plate 3 is connected to piston rod inside cylinder 2, motor 6 is mounted on movable plate 3, rotating shaft 7 is connected to motor 6, and after motor 6 starts, it drives rotating shaft 7 and cleaning wheel 701 to rotate in sequence.

[0022] When cylinder 2 is activated, it pushes the movable plate 3 to descend, causing the pressure plate 302 to press down on the part body 5, clamping the part body 5 between the pressure plate 302 and the positioning plate 4. This ensures that the part body 5 remains stable during subsequent burr removal. Then, as the movable plate 3 continues to descend, the rotating cleaning wheel 701 moves to the inside of the skirt 501, scraping the burrs on the surface of the skirt 501 into the collection box 8. The skirt 501 fits against the inner wall of the limiting block 401, preventing the skirt 501 from being deformed by the pressure of the cleaning wheel 701, thus ensuring that the structure of the part body 5 remains intact after burr removal.

[0023] After the burrs on the part body 5 are removed, the cylinder 2 drives the movable plate 3 and the pressure plate 302 to reset. The robot first removes the part body 5 with the burrs removed from the positioning plate 4, and then places the part body 5 without the burrs removed on the positioning plate 4. The above operation is repeated to realize the continuous automated burr removal operation of the part body 5, which improves production efficiency.

[0024] Meanwhile, the burrs cleaned from the part body 5 automatically fall into the collection box 8 along the limit block 401. When the collection box 8 is full of burrs, the collection box 8 can be pulled out along the fixing groove 402, and the burrs can be poured out. Finally, the empty collection box 8 can be reinstalled under the positioning plate 4, and the burr treatment operation can be carried out again.

[0025] The working principle of this utility model is as follows: After the part body 5 is placed on the positioning plate 4, the cylinder 2 drives the movable plate 3 to descend, so that the pressure plate 302 fixes the position of the part body 5. At the same time, the rotating cleaning wheel 701 moves to the inside of the skirt 501 and scrapes the burrs on the surface of the skirt 501 into the inside of the collection box 8. The skirt 501 is in contact with the inner wall of the limiting block 401 to prevent the skirt 501 from being deformed by the squeezing of the cleaning wheel 701, thus ensuring that the structure of the part body 5 remains intact after the burrs are removed.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
