Description

Technical Field

[0001] This utility model belongs to the field of CNC machine tools and relates to a mechanism for controlling the swing of a CNC rotary table in a CNC machine tool. Background Technology

[0002] Application CN202422589642.1 discloses a mechanism for controlling the swing of a CNC machine tool's rotary table. The technical solution includes a hollow column, a rotary table surface, and a swing mechanism. The swing mechanism includes a base, a leak-proof cover ring, and a swing assembly. The swing assembly includes a swing cylinder, a swing frame, and a swing stud. During machining, the part is fixed on the rotary table surface. The swing cylinder is activated to push out the swing stud, causing the swing frame to rotate. This rotation, via the hollow column, drives the rotary table surface to rotate, thereby adjusting the position and angle of the part. After machining, debris remains on the rotary table. Operators typically use an air gun to blow it away, which causes the debris to scatter across the machine tool body and the ground. Summary of the Invention

[0003] To address the aforementioned problems, this utility model provides a mechanism for controlling the swing of a CNC rotary table in a CNC machine tool.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a mechanism for controlling the swing of a CNC turntable in a CNC machine tool, comprising a linear motor module, a reducer box connected above the linear motor module, a servo motor connected to the side of the reducer box, a turntable connected above the reducer box, a drive motor provided on the side of the linear motor module, a horizontal rotating rod connected above the drive motor, a first brush connected below the horizontal rotating rod, two second brushes hinged below the horizontal rotating rod, and a spring connecting the two second brushes.

[0005] Preferably, the two second brushes are at an angle of 60°–120°.

[0006] Preferably, two second brushes are disposed at both ends of the first brush, and a limiting plate is disposed between the first brush and the second brushes.

[0007] Preferably, a hook is connected to the side of the reducer box away from the servo motor, and a waste box is connected to the hook.

[0008] Preferably, the waste box is provided with a protrusion, and the lower side of the protrusion is provided with an inclined insertion port corresponding to the hook.

[0009] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This invention features a drive motor mounted on the side of a linear motor module. The drive motor rotates a horizontal rotating rod. When not cleaning, the horizontal rotating rod rotates to the side of the linear motor module to avoid obstructing machining. When cleaning is required, the horizontal rotating rod rotates to the top of the linear motor module, and the turntable passes under the horizontal rotating rod, allowing the first brush to clean the upper side of the turntable. The cleaned debris enters the waste box, preventing debris from flying around when using an air gun to blow dust. Attached Figure Description

[0013] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0014] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0015] like Figure 1 , Figure 2As shown, a mechanism for controlling the swing of a CNC turntable in a CNC machine tool includes a linear motor module 1, a reducer box 2 connected above the linear motor module 1, a servo motor 3 connected to the side of the reducer box 2, and a turntable 4 connected above the reducer box 2. The servo motor 3 drives the turntable 4 to rotate, and the linear motor module 1 drives the reducer box 2 to move linearly. A drive motor 5 is provided on the side of the linear motor module 1, a horizontal rotating rod 6 is connected above the drive motor 5, and a first brush 7 is connected below the horizontal rotating rod 6. The first brush 7 is used to clean the upper side of the turntable 4. Two second brushes 8 are hinged below the horizontal rotating rod 6. The second brushes 8 are used to clean the side of the turntable 4. A spring 9 is connected between the two second brushes 8 and is positioned above the second brushes 8 to prevent the turntable 4 from obstructing its passage between the two second brushes 8.

[0016] The utility model is used as follows: When not in operation, the drive motor 5 drives the horizontal rotating rod 6 to rotate to the side of the linear motor module 1. When preparing to start operation, the drive motor 5 drives the horizontal rotating rod 6 to rotate above the linear motor module 1. Then, the linear motor module 1 drives the turntable 4 to pass under the horizontal rotating rod 6, so that the first brush 7 cleans the upper side of the turntable 4. The turntable 4 passes between the two second brushes 8. The two second brushes 8 are attached to the side of the turntable 4 under the pull of the spring 9. The second brushes 8 rotate as the turntable 4 moves.

[0017] Furthermore, the two second brushes 8 form an angle of 60°–120° between them.

[0018] Furthermore, two second brushes 8 are positioned at both ends of the first brush 7, and a limit plate 10 is provided between the first brush 7 and the second brushes 8 to prevent the second brushes 8 from rotating excessively.

[0019] Furthermore, a hook 11 is connected to the side of the reducer box 2 away from the servo motor 3, and a waste box 12 is connected to the hook 11. When the turntable 4 moves closer to the first brush 7, the debris swept off the turntable 4 by the first brush 7 enters the waste box 12.

[0020] Furthermore, the waste box 12 is provided with a protrusion 13, and the lower side of the protrusion 13 is provided with an inclined insertion port 14 corresponding to the hook 11.

[0021] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
