[0012] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following combines the drawings and preferred embodiments to detail the specific implementation manner, structure, features, and effects according to the present utility model as follows.
[0013] Embodiment 1:
[0014] As Figures 1-3As shown in the figure, the utility model discloses a device for scraping burrs on the surface of a columnar die-casting part, which comprises a substrate 1. A rotating shaft 2 is vertically arranged on the substrate 1. An active turntable 3 is arranged on the rotating shaft 2 above the substrate 1. A first motor 9 is arranged on the lower surface of the substrate 1, and the first motor 9 is in transmission connection with the rotating shaft 2. A dust-proof cover 8 with a U-shaped structure is rotatably arranged on the substrate 1. The active turntable 3 is within the range of the dust-proof cover 8, and there is a gap between the active turntable 3 and the dust-proof cover 8. A slide rail 4 is arranged on the substrate 1 on one side of the active turntable 3. One end of the slide rail 4 faces the active turntable 3. A moving plate 5 is slidably connected to the slide rail 4. An installation frame 6 is arranged on the moving plate 5. A vertical scraper 7 is arranged on the installation frame 6 close to the active turntable 3. A second motor 14 is arranged at the end of the slide rail 4. A lead screw 15 is arranged at the end of the second motor 14, and the lead screw 15 is in mating connection with a threaded hole on the moving plate 5. A column 10 is arranged on the substrate 1. The top end of the column 10 extends to the directly upper end of the active turntable 3. A vertically downward cylinder 11 is arranged on the column 10 at the directly upper end of the active turntable 3. The telescopic end of the cylinder 11 is rotatably provided with a pressing table 12. The columnar die-casting part is arranged between the active turntable 3 and the pressing table 12. A baffle 13 is arranged on the moving plate 5. When the moving plate 5 approaches the active turntable 3 until the scraper 7 contacts the columnar die-casting part, the baffle 13 blocks the opening of the dust-proof cover 8.
[0015] In actual situations, the substrate 1 can be of a rectangular structure. Since the dust-proof cover 8 can rotate, the slide rail 4 can be arranged parallel to the long side direction of the substrate 1. When assembling the workpiece, the opening of the dust-proof cover 8 can be rotated 90° to face the short side direction of the substrate 1. In this state, when the operator puts the workpiece into the opening of the dust-proof cover 8, the scraper 7 is located outside the dust-proof cover 8, so the safety is effectively guaranteed. This enables the moving distance of the scraper 7 not to be too far, and only needs to move out of the range of the dust-proof cover 8. After the workpiece is assembled, the cylinder 11 presses down, and the workpiece is clamped between the pressing table 12 and the active turntable 3. The opening of the dust-proof cover 8 turns towards the slide rail 4, then the slide rail 4 pushes the moving plate 5 into the dust-proof cover 8, the scraper 7 approaches and contacts the workpiece, and at this time the baffle 13 blocks the opening of the dust-proof cover 8. The first motor 9 drives the active turntable 3 to rotate, so that the workpiece and the pressing table 12 also rotate accordingly, and the burrs on the surface of the workpiece can be scraped off. This process is safe and reliable, can effectively avoid the situation that the scraper 7 harms the human body, and can also reduce the required movement stroke of the scraper 7, improving the efficiency.
[0016] The dust cover 8 includes an arc portion 81 and a flat portion 82. The arc portion 81 is in a 180° arc shape, and the two flat portions 82 are respectively tangentially connected to the ends of the arc portion 81. An arc-shaped chute 17 is provided on the substrate 1 corresponding to the arc portion 81, and an arc-shaped slider 16 is provided on the arc portion 81. The arc-shaped chute 17 and the arc-shaped slider 16 are slidably connected in cooperation. An arc-shaped rack 20 is provided on the arc portion 81, and a third motor 22 is provided on the side of the arc portion 81. A driving gear 19 is provided on the output shaft of the third motor 22, and the driving gear 19 meshes with the arc-shaped rack 20.
[0017] The adopted dust cover 8 is U-shaped, including an arc portion 81 and a flat portion 82. The arc portion 81 is 180°, so the overall opening is relatively large, which is convenient for the assembly of workpieces. The designed rotation angle of the dust cover 8 is 90°. The cooperation of the arc-shaped chute 17 and the arc-shaped slider 16 makes the rotation stability of the dust cover 8 higher. By using the cooperation of the driving gear 19 of the third motor 22 and the arc-shaped rack 20, the rotation stability can be improved.
[0018] A chip discharge port 21 is provided on the substrate 1 within the range covered by the rotation of the arc portion 81 of the dust cover 8. The chip discharge port 21 penetrates through the substrate 1, and a dust suction hood 18 is provided on the lower surface of the substrate 1. The dust suction hood 18 is connected to a dust suction mechanism. The chip discharge port 21 is provided below the active turntable 3, and the metal chips scraped off are sucked by the dust suction hood 18 below, making the processing environment better. The dust suction mechanism is, for example, a vacuum cleaner. Automatic dust suction can reduce the cleaning of the substrate 1 and improve the processing efficiency.
[0019] There are two columns 10, and the columns 10 are arranged at positions corresponding to two adjacent side walls of the substrate 1. The upper ends of the columns 10 extend upward directly above the active turntable 3 and are connected as a whole. The design of the columns 10 with this structure will not interfere with the rotation of the dust cover 8, and the overall strength and stability are high.
