[0024] In the related art, the electrical pipeline of the A-axis and the hydraulic pipeline of the C-axis in the five-axis swing head both pass through the center of the C-axis rotor bushing. As the C-axis rotor rotates, under the condition of continuous rotation of ±360°, the electrical pipeline and the hydraulic pipeline will be wound together, resulting in fatigue of the hydraulic pipeline and finally bursting of the pipeline.

[0025] To solve the above technical problems, the present application provides a five-axis swing head structure with separated electrical and hydraulic pipelines.

[0026] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of the five-axis swing head structure with separated electrical and hydraulic pipelines provided by the embodiments of the present application.

[0027] Refer to Figure 1 , the present application provides a five-axis swing head structure with separated electrical and hydraulic pipelines. The five-axis swing head structure 1000 includes a C-axis assembly 100, an electrical pipeline 200, and a hydraulic pipeline 300. The C-axis assembly 100 includes a stator outer sleeve 110 and a rotary oil cylinder assembly 120. The rotary oil cylinder assembly 120 includes a body 121 and a bushing 122. The body 121 is fixed on the stator outer sleeve 110. The bushing 122 is slidably connected to the outer periphery of the body 121. Among them, the body 121 is provided with a first through hole 123 penetrating along the axial direction of the body 121 and a first hydraulic flow channel 124 spaced from the first through hole 123. The bushing 122 is provided with a second hydraulic flow channel 125 corresponding to the first hydraulic flow channel 124. The side wall of the body 121 is provided with a second through hole (not shown in the figure) connecting the first hydraulic flow channel 124 and the second hydraulic flow channel 125. The electrical pipeline 200 penetrates through the first through hole 123. The hydraulic pipeline 300 is configured to connect the first hydraulic flow channel 124 and the second hydraulic flow channel 125.

[0028] In the technical solution of this embodiment, the present application separates the electrical pipeline 200 and the hydraulic pipeline 300 in the C-axis assembly 100 to avoid mutual interference between the two. The electrical pipeline 200 penetrates through the main body 121 via the first through hole 123, while the hydraulic pipeline 300 is connected through the first hydraulic flow channel 124, the second hydraulic flow channel 125, and a second through hole (not shown in the figure), ensuring that the two pipelines will not be entangled or collided. Through the structural design of the main body 121 and the bushing 122 of the rotary cylinder assembly 120, the first through hole 123 and the first hydraulic flow channel 124 are arranged at intervals, and the second hydraulic flow channel 125 is arranged on the bushing 122. This spatial layout makes rational use of the space inside the C-axis assembly 100. While providing independent channels for the electrical pipeline 200 and the hydraulic pipeline 300, the overall structure is made more compact. Moreover, the independent design of the electrical pipeline 200 and the hydraulic pipeline 300 makes it easier to operate during equipment assembly. The electrical pipeline 200 can easily penetrate through the main body 121 via the first through hole 123, while the hydraulic pipeline 300 is connected through the first hydraulic flow channel 124, the second hydraulic flow channel 125, and a second through hole (not shown in the figure), reducing the complexity during the installation process and improving the installation efficiency.

[0029] In one embodiment, the hydraulic pipeline 300 includes a first hydraulic pipeline 310 and a second hydraulic pipeline 320. The first hydraulic pipeline 310 is arranged at the end of the first hydraulic flow channel 124 away from the second hydraulic flow channel 125. The second hydraulic pipeline 320 is arranged at the end of the second hydraulic flow channel 125 away from the first hydraulic flow channel 124.

[0030] In the technical solution of this embodiment, by arranging the first hydraulic pipeline 310 at the end of the first hydraulic flow channel 124 away from the second hydraulic flow channel 125, and the second hydraulic pipeline 320 at the end of the second hydraulic flow channel 125 away from the first hydraulic flow channel 124, it is possible to avoid the first hydraulic pipeline 310 and the second hydraulic pipeline 320 from being entangled with each other in space and make the overall structure more compact. In addition, this design also facilitates installation and debugging. The staff can easily connect the first hydraulic pipeline 310 and the second hydraulic pipeline 320 to the corresponding flow channels without worrying about entanglement problems. During the debugging process, it is also more convenient to check and adjust the connections between the first hydraulic pipeline 310, the second hydraulic pipeline 320, and the corresponding flow channels to ensure the normal operation of the equipment.

[0031] In a specific implementation manner, both the first hydraulic pipeline 310 and the second hydraulic pipeline 320 include rubber hoses. Rubber hoses are more flexible and are easier to arrange during installation, especially in places where space is limited or bending is required. In addition, the rubber hoses have better shock absorption effects. There will be pressure fluctuations and vibrations during the operation of the system, and the elasticity of the rubber hoses can absorb these vibrations, reducing the impact on other components of the system, thereby extending the overall service life.

[0032] In one embodiment, at least one first annular groove 400 is provided on the outer peripheral side wall of the body 121. The first annular groove 400 continuously extends along the radial outer peripheral surface of the body 121. The opening of the first annular groove 400 is covered by the outer peripheral side wall of the bushing 122, and a second through hole (not shown in the figure) is provided at the bottom of the first annular groove 400.

[0033] In the technical solution of this embodiment, by providing a second through hole (not shown in the figure) at the bottom of the first annular groove 400, the arc transition of the first annular groove 400 can be used to disperse stress. The first annular groove 400 serves as a fluid buffer chamber, which can reduce the sudden change in flow velocity at the entrance of the second through hole (not shown in the figure). The opening of the first annular groove 400 is covered by the outer peripheral side wall of the bushing 122, which can effectively prevent external impurities such as dust from entering the interior of the body 121 through the opening. This design ensures that the internal structure of the body 121 is not affected by the external environment and improves the reliability of the device.

[0034] In one embodiment, at least two second annular grooves 500 are further provided on the outer peripheral side wall of the body 121. One second annular groove 500 is provided on each side of the first annular groove 400. A seal (not shown in the figure) is provided in the second annular groove 500.

[0035] In the technical solution of this embodiment, the seal (not shown in the figure) provided in the second annular groove 500 can provide a sealing structure to prevent fluid leakage. By providing second annular grooves 500 on each side of the first annular groove 400, the sealing performance of the system can be improved. In this application, one second annular groove 500 is provided on each side of the first annular groove 400. By sharing one second annular groove 500 for every two adjacent first annular grooves 400, the number of second annular grooves 500 can be reduced, thereby significantly shortening the axial length and making the overall structure more compact. In addition, reducing the number of second annular grooves 500 can also reduce the number of seals (not shown in the figure), thereby saving manufacturing costs.

[0036] In a specific implementation manner, the seal (not shown in the figure) includes a sealing ring. By providing a sealing ring in the second annular groove 500, the sealing performance of the system can be significantly improved. In this application, the sealing ring includes an O-ring, an X-ring, a Y-ring, a U-ring, etc., and users can select according to actual needs, which are not specifically limited here. The materials of the sealing ring include styrene-butadiene rubber, fluororubber, silicone rubber, polytetrafluoroethylene, polyurethane, etc.

[0037] In one embodiment, the five-axis swing head structure 1000 further includes a first connection component (not shown in the figure) and a second connection component (not shown in the figure). The first connection component (not shown in the figure) is disposed between the first hydraulic flow channel 124 and the first hydraulic pipeline 310 for forming a fluid-tight connection. The second connection component (not shown in the figure) is disposed between the second hydraulic flow channel 125 and the second hydraulic pipeline 320 for forming a fluid-tight connection.

[0038] In the technical solution of this embodiment, a fluid-tight connection can be formed through the settings of the first connection component (not shown in the figure) and the second connection component (not shown in the figure), reducing the risk of fluid in the hydraulic flow channel leaking into the external environment. Moreover, the designs of the first connection component (not shown in the figure) and the second connection component (not shown in the figure) make the connection between the hydraulic pipeline 300 and the hydraulic flow channel more convenient. During the installation process, this structure can complete the connection quickly, reducing the commissioning time and making it easier to disassemble and replace damaged components during maintenance.

[0039] In one embodiment, the first connection component (not shown in the figure) includes a first interface (not shown in the figure) and a second interface (not shown in the figure). The first interface (not shown in the figure) is disposed at the end of the first hydraulic pipeline 310 close to the first hydraulic flow channel 124, and the second interface (not shown in the figure) is disposed at the end of the first hydraulic flow channel 124 close to the first hydraulic pipeline 310. The first interface (not shown in the figure) and the second interface (not shown in the figure) form a detachable fluid-tight connection.

[0040] In the technical solution of this embodiment, the detachable design of the first interface (not shown in the figure) and the second interface (not shown in the figure) endows the five-axis swing head structure 1000 with higher modular characteristics. If it is necessary to adjust or upgrade the five-axis swing head structure 1000, new interfaces and pipelines can be conveniently replaced or added. Since the first interface (not shown in the figure) and the second interface (not shown in the figure) can be easily separated and reconnected, the installation process can be made more flexible. If a certain component needs to be replaced or repaired, only the component to be replaced needs to be removed for operation without disassembling the entire structure.

[0041] In one embodiment, the second connection component (not shown in the figure) includes a third interface (not shown in the figure) and a fourth interface (not shown in the figure). The third interface (not shown in the figure) is disposed at the end of the second hydraulic pipeline 320 close to the second hydraulic flow channel 125. The fourth interface (not shown in the figure) is disposed at the end of the second hydraulic flow channel 125 close to the second hydraulic pipeline 320. The third interface (not shown in the figure) and the fourth interface (not shown in the figure) form a detachable fluid-tight connection.

[0042] In the technical solution of this embodiment, the detachable third interface (not shown in the figure) and the fourth interface (not shown in the figure) are designed such that the five-axis swing head structure 1000 has higher modular characteristics. If it is necessary to adjust or upgrade the five-axis swing head structure 1000, new interfaces and pipelines can be conveniently replaced or added. Since the third interface (not shown in the figure) and the fourth interface (not shown in the figure) can be easily separated and reconnected, the installation process can be made more flexible. If a certain component needs to be replaced or repaired, only the component to be replaced needs to be removed for operation, without disassembling the entire structure.

[0043] In one embodiment, the swing cylinder assembly 120 is provided with at least two first hydraulic channels 124, at least two second hydraulic channels 125, and at least two second through holes (not shown in the figure) that connect the first hydraulic channels 124 and the second hydraulic channels 125.

[0044] In the technical solution of this embodiment, when the number of the first hydraulic channels 124 and the second hydraulic channels 125 is at least two, different types of fluids can be allowed to be transmitted and circulated through different channels, thereby improving the versatility and expandability of the system. As Figure 1 shown, although the number of the first hydraulic channels 124 and the second hydraulic channels 125 is exemplarily shown as two, in fact, the number of the first hydraulic channels 124 and the second hydraulic channels 125 can be extended to multiple designs according to specific application scenarios.

[0045] In one embodiment, in the body 121, at least two first hydraulic channels 124 are arranged at intervals, and in the bushing 122, at least two second hydraulic channels 125 are arranged at intervals; the number of the first hydraulic channels 124, the second hydraulic channels 125, the first hydraulic pipelines 310, the second hydraulic pipelines 320, and the second through holes (not shown in the figure) are equal and correspond one by one.

[0046] In the technical solution of this embodiment, in the body 121, the first hydraulic channels 124 are arranged at intervals, and in the bushing 122, the second hydraulic channels 125 are arranged at intervals, and the number of the first hydraulic channels 124, the second hydraulic channels 125, the first hydraulic pipelines 310, the second hydraulic pipelines 320, and the second through holes (not shown in the figure) are equal and correspond one by one, which can make each channel, pipeline, and through hole form an independent fluid circulation path. Different types of fluids can be transmitted and circulated through different channels without mixing or interfering with each other. This design can ensure that each fluid works independently in its respective channel without affecting each other. Since each channel, pipeline, and through hole is independently designed, if a certain channel, pipeline, or through hole needs to be cleaned or repaired, it can be operated separately without affecting other parts. This modular independence significantly improves the maintainability and reliability of the system.

[0047] In one embodiment, the C-axis assembly 100 further includes a C-axis rotor 130 and a C-axis stator 140. The C-axis rotor 130 is fixedly sleeved on the outer periphery of the bushing 122. The C-axis stator 140 is fixedly arranged on the inner periphery of the stator outer sleeve 110 and is spaced apart from the C-axis rotor 130. An exciting coil is arranged inside the C-axis stator 140.

[0048] In the technical solution of this embodiment, the C-axis rotor 130 is fixedly sleeved on the outer periphery of the bushing 122 and is spaced apart from the C-axis stator 140. This structural design can ensure a certain gap between the C-axis rotor 130 and the C-axis stator 140, avoiding mechanical friction or interference. At the same time, the fixed installation methods of the C-axis rotor 130 and the C-axis stator 140 ensure the relative position stability between the C-axis rotor 130 and the C-axis stator 140, thereby improving the rotation accuracy and the stability of the system. The strong magnetic field generated by the exciting coil arranged inside the C-axis stator 140 interacts with the C-axis rotor 130 to generate a relatively large electromagnetic driving torque, so that the C-axis assembly 100 can output a higher torque.

[0049] In one embodiment, the five-axis swivel head structure 1000 includes an A-axis assembly 600. The bushing 122 is fixedly arranged on the A-axis assembly 600.

[0050] In the technical solution of this embodiment, the A-axis assembly 600 rotates around the X-axis. Fixing the bushing 122 on the A-axis assembly 600 can improve the rigidity and stability of the overall structure.

[0051] The working process of the five-axis swivel head structure 1000 is described in detail below.

[0052] After the C-axis stator 140 is powered on, an electromagnetic field is generated, and the C-axis rotor 130 starts to rotate under the action of the electromagnetic field. Since the C-axis rotor 130 is fixedly sleeved on the outer periphery of the bushing 122, therefore, the bushing 122 also rotates with the rotation of the C-axis rotor 130. Since the bushing 122 is slidably connected to the body 121, the body 121 does not rotate with the rotation of the bushing 122. The electrical pipeline 200 passes through the first through hole 123 to achieve the transmission of signals or power. Since the bushing 122 and the A-axis assembly 600 are fixedly connected, when the bushing 122 is in a rotating state, the A-axis assembly 600 also rotates accordingly. Therefore, the electrical pipeline 200 extending from the A-axis assembly 600 also rotates accordingly. And since the body 121 does not rotate with the rotation of the bushing 122, it is beneficial to reduce the degree of winding of the electrical pipeline 200.

[0053] The fluid flows successively from the second hydraulic pipeline 320 extending from the A-axis assembly 600, the second hydraulic flow channel 125, and the first hydraulic flow channel 124 into the first hydraulic pipeline 310. The second hydraulic pipeline 320 fixedly arranged on the A-axis assembly 600 and the second hydraulic flow channel 125 arranged on the bushing 122 rotate as the bushing 122 rotates. The first hydraulic flow channel 124 arranged inside the body 121 and the first hydraulic pipeline 310 arranged on the end face of the swing cylinder 120 do not rotate because the body 121 does not rotate with the rotation of the bushing 122, so the first hydraulic pipeline 310 does not rotate either, and the problem of pipeline entanglement will not occur. In summary, arranging the electrical pipeline 200 and the hydraulic pipeline 300 separately in the C-axis assembly 100 can avoid the electrical pipeline 200 and the hydraulic pipeline 300 from winding around each other.

[0054] The C-axis assembly 100 is fixedly connected to the A-axis assembly 600 through the bushing 122. When the C-axis assembly 100 rotates, it will drive the A-axis assembly 600 to rotate along the rotation axis of the C-axis assembly 100. When the A-axis assembly 600 rotates, it will drive the C-axis assembly 100 to rotate along the rotation axis of the A-axis assembly 600, so that the entire five-axis swing head structure 1000 realizes complex angular spatial movements.

[0055] The above is only the implementation mode of this application, and does not limit the patent scope of this application accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of this application, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of this application.
