During operation, by setting a base 1, the base 1 is placed on top of the turntable 3. A support column 2 is fixed to the end of the base 1. A rotatable turntable 3 is set at the top of the support column 2. A placement groove 4 is opened at the top of the turntable 3 for placing the workpiece that needs to be drilled. A horizontal column 5 is set on one side of the base 1. An L-shaped plate 6 is fixed to the top of the horizontal column 5. A drilling machine 8 is fixed to the bottom of the L-shaped plate 6 through a flat plate 7. The drilling machine 8 can drill the workpiece in the placement groove 4 by being driven by the extension rod 9 of the first cylinder. The waste generated by the drilling machine 8 during the drilling of the workpiece is cleaned by a cleaning component to prevent waste from remaining on the surface of the turntable 3. A gear ring 13 is fixed to the bottom of the turntable 3. A half gear 1 is fixed to the top of the rotating shaft 12. 4. The gear ring 13 meshes with the half gear 14, allowing the turntable 3 and gear ring 13 to rotate at a quarter rotational force at the top of the support column 2, so that the placement slot 4 stops on the front of the L-shaped plate 6, facilitating the drilling machine 8 to drill the workpiece. Here, the speed of the motor 11 needs to ensure that the half gear 14 can re-engage the gear ring 13 when the drilling machine 8 is retracted by the first cylinder extension rod 9 and does not contact the workpiece, so that the turntable 3 rotates by a quarter of the amount, thus allowing the drilled workpiece to be moved away, and the un-drilled workpiece to be rotated below the drilling machine 8 for drilling.
[0018] The cleaning assembly includes a drop trough 15 and a transmission unit; the drop trough 15 is located at the top of the turntable 3 and passes through the support column 2; the support plate 10 extends into the support column 2; a rotating rod 16 is rotatably connected to the top of the support plate 10 inside the support column 2, and one end of the rotating rod 16 passes through the support plate 10; one end of the rotating rod 16 extends upward to the top of the turntable 3; a sweeping plate 17 is fixedly connected to the outer circular wall of the rotating rod 16; the sweeping plate 17 is rotatably connected to the top of the turntable 3; a connecting plate 18 is fixedly connected to the outer circular wall of the rotating rod 16; the connecting plate 18 is rotatably connected to the top of the support plate 10. During operation, by moving the support plate 10... The 0 penetrates into the support column 2, and a drop groove 15 is opened at the top of the turntable 3, so that the drop groove 15 penetrates the support column 2. By setting a rotating rod 16 at the top of the support plate 10 inside the support column 2, the rotating rod 16 drives the cleaning plate 17 to rotate at the top of the turntable 3 through the transmission unit, and sweeps the waste generated by the drilling machine 8 into the drop groove 15 for collection. This not only avoids the waste from being left on the surface of the turntable 3 and causing damage to the turntable 3, but also avoids the drawback of the operator having to stop the machine to clean the surface of the turntable 3. The connecting plate 18 set on the outer circular wall of the rotating rod 16 can clean up the waste that falls on the top of the support plate 10.
[0019] The transmission unit includes a first sprocket 19; the first sprocket 19 is fixed to the outer circular wall of the rotating shaft 12; a second sprocket 20 is fixed to the outer circular wall of the rotating rod 16; the first sprocket 19 and the second sprocket 20 are connected by a chain 21. During operation, by fixing the first sprocket 19 to the outer circular wall of the rotating shaft 12, the first sprocket 19 drives the second sprocket 20 on the outer circular wall of the rotating rod 16, causing the rotating rod 16 to rotate. This drives the cleaning plate 17 to clean the top of the turntable 3, thus completing the cleaning work on the surface of the turntable 3.
[0020] A vertical plate 22 is fixedly connected to the top of the horizontal column 5; a semi-circular block 23 is fixedly connected to the top of the vertical plate 22; a second cylinder telescopic rod 24 is fixedly connected to one side of the semi-circular block 23, and one end of the second telescopic rod passes through the semi-circular block 23; an arc-shaped block 25 is fixedly connected to the telescopic end of the second cylinder telescopic rod 24; the arc-shaped block 25 is slidably connected in the placement groove 4. During operation, by fixing the top of the horizontal column 5 to the vertical plate 22, and setting the top of the vertical plate 22 through the semi-circular block 23 to set the second cylinder telescopic rod 24, when the motor 11 drives the turntable 3 to rotate to the front of the arc-shaped block 25, the second cylinder telescopic rod 24 will drive the arc-shaped block 25 to squeeze and clamp the workpiece in the placement groove 4, so as to prevent the workpiece from rotating when the drilling machine 8 enters the drilling hole. Here, the second cylinder telescopic rod 24 needs to be set to extend faster than the first cylinder telescopic rod 9, and retract slightly slower than the first cylinder telescopic rod 9.
[0021] A groove 26 is provided on the outer circular wall of the base 1; a collection box 27 is slidably connected in the groove 26; the drop trough 15 communicates with the groove 26. During operation, by opening a groove on the outer circular wall of the base 1, and then setting a slidably connected groove 26 in the groove 26, and connecting the drop trough 15 with the groove 26, the waste swept by the cleaning component can fall into the collection box 27 through the drop trough 15 for collection and unified cleaning.
[0022] The base 1 is equipped with an anti-slip pad at its bottom. During operation, the anti-slip pad at the bottom of the base 1 can effectively increase the friction between the turntable and the ground or worktable, preventing it from sliding and ensuring the stability of the operation process. This is because the turntable may slip due to vibration or external factors during operation, which could affect the accuracy of the operation or even cause a safety accident.
[0023] Working principle: A base 1 is set up, and a support column 2 is fixed to the top of the base 1. A rotatable turntable 3 is set at the top of the support column 2. A placement groove 4 is opened at the top of the turntable 3 for placing the workpiece that needs to be drilled. A horizontal column 5 is set on one side of the base 1. An L-shaped plate 6 is fixed to the top of the horizontal column 5. A drilling machine 8 is fixed to the bottom of the L-shaped plate 6 through a flat plate 7. The drilling machine 8 is driven by the telescopic rod 9 of the first cylinder to drill the workpiece in the placement groove 4. The waste generated by the drilling machine 8 during the drilling of the workpiece is cleaned by a cleaning component to prevent waste from remaining on the surface of the turntable 3. A gear ring 13 is fixed to the bottom of the turntable 3. A half gear 14 is fixed to the top of the rotating shaft 12, and the gear ring 13 meshes with the half gear 14. In this way, the turntable 3 and the gear ring 13 can be positioned at the top of the support column 2 in a four-way configuration. One-quarter of the rotation power rotates the plate 4 to stop in front of the L-shaped plate 6, facilitating the drilling machine 8 to drill the workpiece. The speed of the motor 11 must be such that when the drilling machine 8 retracts with the first cylinder extension rod 9 and does not contact the workpiece, the teeth of the half-gear 14 can re-engage with the gear ring 13, causing the turntable 3 to rotate a quarter of the way. This allows the drilled workpiece to be moved away, while the un-drilled workpiece is moved below the drilling machine 8 for drilling. A drop groove 15 is created at the top of the turntable 3 by extending the support plate 10 through the support column 2, allowing the drop groove 15 to penetrate the support column 2. A rotating rod 16 is installed at the top of the support plate 10 inside the support column 2, driven by a transmission unit, causing the cleaning plate 17 to move on the turntable. The top of the rotating rod 16 rotates to sweep the waste generated during the drilling of the rotating machine 8 into the drop trough 15 for collection. This not only avoids the waste from remaining on the surface of the rotating rod 3 and causing damage, but also avoids the inconvenience of having to stop the machine to clean the surface of the rotating rod 3. The connecting plate 18 on the outer circular wall of the rotating rod 16 can clean up the waste that falls on the top of the support plate 10. By fixing the first sprocket 19 to the outer circular wall of the rotating shaft 12, the first sprocket 19 drives the second sprocket 20 on the outer circular wall of the rotating rod 16, causing the rotating rod 16 to rotate. This drives the cleaning plate 17 to clean the top of the rotating rod 3, thus completing the cleaning work on the surface of the rotating rod 3. By fixing the top of the horizontal column 5 to the vertical plate 22, and then passing the top of the vertical plate 22 through a semi-circular plate 22... The circular block 23 is equipped with a second cylinder telescopic rod 24. When the motor 11 drives the turntable 3 to rotate to the front of the arc-shaped block 25, the second cylinder telescopic rod 24 will drive the arc-shaped block 25 to squeeze and clamp the workpiece in the placement groove 4, preventing the workpiece from rotating when the drilling machine 8 enters the drilling hole. Here, the second cylinder telescopic rod 24 needs to be set to extend faster than the first cylinder telescopic rod 9, and retract slightly slower than the first cylinder telescopic rod 9. By opening a groove on the outer circular wall of the base 1, and setting a sliding connection groove 26 in the groove 26, and connecting the drop groove 15 and the groove 26, the waste cleaned by the cleaning component can fall into the collection box 27 through the drop groove 15 for collection and unified cleaning. By setting an anti-slip pad at the bottom of the base 1, the workpiece can be cleaned during operation.Turntable machines may slip due to vibration or external factors, affecting operational accuracy and even causing safety accidents. Anti-slip mats effectively increase the friction between the turntable machine and the ground or worktable, preventing slippage and ensuring stability during operation.
