It should be understood that the scales shown in the accompanying drawings are not those of the actual implementation of the present invention. These scales are for illustrative purposes only and are not drawn to scale.

[0036] Please see Figure 1 and Figure 2 A first embodiment of the present invention provides a turntable device, including a first swing arm 100 , a second swing arm 200 , a bridge plate 300 and a workbench assembly 400 .

[0037] The first swing arm 100, the second swing arm 200, the bridge plate body 300 and the workbench assembly 400 can rotate around the rotation axis L. That is, the first swing arm 100, the second swing arm 200, the bridge plate body 300 and the mounting seat 500 constitute an A-axis assembly, and the workbench assembly 400 is a C-axis assembly.

[0038] The first and second swing arms 100 and 200 are mounted on either side of the bridge plate 300. A mounting base 500 is provided on the bridge plate 300, and the workbench assembly 400 is rotatably mounted on the mounting base 500. A first input channel A1 is disposed within the mounting base 500. The input port of the first input channel A1 is located above the bridge plate 300, extending downward along the mounting base 500. The output port of the first input channel A1 is annular. This ensures that the first input channel A1 remains connected to the first output channel B1 when the workbench assembly 400 rotates relative to the mounting base 500.

[0039] It is understood that the workbench assembly 400 is provided with a fixture driver that is in communication with the first output channel B1. For example, the input port of the first input channel A1 is in communication with a gas source, such that the gas source delivers gas to the fixture driver on the surface of the workbench assembly 400 through the first input channel A1 and the first output channel B1. For another example, the input port of the first input channel A1 is in communication with a hydraulic source, such that the fixture driver is hydraulically driven.

[0040] In order to facilitate the assembly of the workbench assembly 400, the workbench assembly 400 includes a shaft 410 and a workbench 420. The workbench assembly 400 is provided with a first output channel B1. The shaft 410 is inserted into the mounting seat 500. The workbench 420 is fixed to the top of the shaft 410 and is located above the mounting seat 500. The input port of the first output channel B1 is located on the outer periphery of the shaft 410 and is connected to the annular output port of the first input channel A1. The output port of the first output channel B1 is provided on the surface of the workbench 420. It can be understood that a clamp driving member is provided on the surface of the workbench 420. The above structural arrangement can reduce the space occupied by the external pipeline connected to the input port of the first input channel, which is beneficial to the safety of the external pipeline when the turntable rotates.

[0041] To facilitate the installation of the first input channel A1, in some embodiments, the mounting base 500 includes a cylindrical body 510 and a bottom cover 520 fixed to the bottom end of the cylindrical body 510. The shaft 410 is inserted into the center hole of the bottom cover 520 and rotatably engages with the bottom cover 520. The first input channel A1 includes an axial channel A11 and a radial channel A12. The upper end of the axial channel A11 connects to the input port of the first input channel A1, and the lower end of the axial channel A11 connects to the radial channel A12. The radial channel A12 communicates with the center hole of the bottom cover 520 and forms an annular groove therein. The annular groove serves as the output port of the first input channel A1. Sealing structures 530 are provided on both sides of the annular output port of the first input channel A1. It is understood that the axial channel A11 can be formed by vertically drilling in the cylindrical body 510, and the radial channel A12 can be formed by horizontally drilling in the bottom cover 520, thereby facilitating the processing and formation of the first input channel A1 on the mounting base 500.

A cooling channel D is provided between the outer periphery of the motor 600 and the barrel 510, wherein the input port of the cooling channel D communicates with the second input channel A2, and the output port of the cooling channel D communicates with the second output channel B2. In addition to facilitating the rational arrangement of the cooling channels, the above-described structural arrangement also allows the pipeline connected to the second input channel A2 to be located above the bridge plate 300, and facilitates the connection of the pipeline connected to the second input channel A2 to the outside of the turntable device through the first wire hole C1, thereby reducing the length of the external pipeline.

[0045] Please see Figure 3 In some embodiments, in order to increase the length of the cooling groove of the cooling channel D so that the cooling channel D can accommodate more coolant and improve the cooling effect on the motor 600, the cooling channel D is spirally arranged on the periphery of the motor 600, and the height of the input port of the cooling channel D is lower than the height of the output port of the cooling channel D. Sealing structures 530 are provided on the upper and lower sides of the cooling channel D, so that the motor 600 can be cooled in time to ensure the high-speed rotation of the motor 600, so that the liquid level flows from low to high, reducing the air in the cooling channel D and improving the cooling efficiency of the motor 600.

[0046] Please see Figure 3 In some embodiments, in order to facilitate the installation of the motor 600 and the installation of the workbench 420, the shaft body 410 is configured to include a dynamic rotating shaft 411 and a core shaft 412. The workbench 420, the core shaft 412 and the dynamic rotating shaft 411 are fixedly arranged in sequence along the vertical direction, and the motor 600 is sleeved on the outer periphery of the dynamic rotating shaft 411.

[0047] In order to ensure the sealing of the cooling channel D and prevent the coolant from leaking out of the cooling channel D, in some embodiments, the cooling channel D includes at least two circles of spiral channels, and seals 601 are provided on both sides of each circle of spiral channels, thereby improving the sealing effect of adjacent spiral channels.
