[0002] At present, there is an increasing demand for five-axis machining and high-efficiency and high-precision machining of complex products in the fields of automobiles, aerospace, and medical treatment. In order to achieve five-axis machining, the existing solution is to add a single-axis or dual-axis CNC turntable to the CNC machine tool to complete indexing or linkage machining. In order to efficiently complete mass production tasks, multiple machine tools are often required, which is not only costly, but also has high requirements for site space. Although double-head machines and multi-head machines can improve machining efficiency and save space to a certain extent, for CNC turntables, each additional workpiece installed requires the turntable to have a larger load, especially for some heavier parts, which have higher requirements for motor load.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0018] In the description of the embodiments of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific circumstances.

[0019] Figure 1 and Figure 2 An embodiment of a multi-axis rotary table of the utility model is shown, comprising a first swing unit 1, a second swing unit 2, a rotating base 3, a first rotating unit 4 and a second rotating unit 5. One end of the rotating base 3 is connected to the first swing unit 1, and one end is connected to the second swing unit 2. The first rotating unit 4 and the second rotating unit 5 are installed on the rotating base 3 side by side.

[0020] The first swing unit 1 includes a first support 11, a first drive motor 12 and a first swing shaft 13. The first drive motor 12 is installed in the first support 11. The first swing shaft 13 is installed at the output end of the first drive motor 12 and is supported in the first support 11 through a first bearing 14. It can rotate around its central axis under the drive of the first drive motor 12.

[0021] The second swing unit 2 includes a second support 21, a second drive motor 22 and a second swing shaft 23. The second drive motor 22 is installed in the second support 21. The second swing shaft 23 is installed at the output end of the second drive motor 22 and is supported in the second support 21 through a second bearing 24. It can rotate around its central axis under the drive of the second drive motor 22.

[0022] The first swing shaft 13 and the second swing shaft 23 are arranged coaxially, and the rotating base 3 is fixedly connected to the first swing shaft 13 and the second swing shaft 23 respectively. With the rotation of the first swing shaft 13 and the second swing shaft 23, the rotating base 3 can swing back and forth around the horizontal axis. The first rotating unit 4 and the second rotating unit 5 are respectively provided with a workbench for mounting a workpiece, which can swing back and forth with the rotating base 3 on the one hand, and rotate along the vertical axis on the other hand, and the rotation axis of the first rotating unit 4 and the second rotating unit 5 and the swing axis of the rotating base 3 are located in the same plane.

[0023] When the present embodiment is working, the first drive motor 12 and the second drive motor 22 can work synchronously, drive the first swing shaft and the second swing shaft to rotate synchronously, and drive the rotating base 3 to swing together, which can provide a large torque, can effectively improve the load capacity of the turntable, enable the turntable to carry heavy workpieces, and is conducive to reducing the size of the turntable and saving internal space. Under load requirements, the first drive motor 12 and the second drive motor 22 can also work independently, and one of the first drive motor 12 and the second drive motor 22 drives the rotating base 3 to swing. When only the first drive motor 12 is working, it can drive the first swing shaft 13 to rotate, and the second swing shaft 23 is rotated synchronously through the rotating base 3, thereby ensuring the swing of the rotating base 3. When only the second drive motor 22 is working, it can drive the second swing shaft 23 to rotate, and the first swing shaft 13 is rotated synchronously through the rotating base 3, thereby ensuring the swing of the rotating base 3.

[0024] The first rotating unit 4 and the second rotating unit 5 can rotate synchronously or independently. When batch processing is performed on the same workpiece, the first rotating unit 4 and the second rotating unit 5 can rotate synchronously to realize double-station five-axis linkage processing, and one clamping can complete the production of two workpieces at the same time, effectively improving the processing efficiency.

[0025] The above embodiment is described by taking the structure in which two rotating units are installed on the rotating base 3 as an example. To further improve the processing efficiency, a larger number of rotating units may be installed on the rotating base 3 . Figure 3 A multi-axis rotary worktable structure provided by another embodiment of the utility model is shown, in which three rotary units are installed on a rotary base 3, namely a first rotary unit 4, a second rotary unit 5 and a third rotary unit 6. The three rotary units can rotate synchronously or independently, thereby realizing multi-station five-axis linkage processing.

[0026] Although the utility model is described in detail above, the utility model is not limited thereto, and those skilled in the art can make various modifications according to the principle of the utility model. Therefore, all modifications made according to the principle of the utility model should be understood to fall within the protection scope of the utility model.
