[0065] Embodiment

[0066] This embodiment provides an overhead fixture pipeline, as Figures 1 to 5 shown, including a base frame, a top joint, a bottom joint, a hose 3, an oil distribution shaft 4, an anti - winding assembly, and a cantilever assembly.

[0067] As Figure 1 and Figure 2 shown, the base frame includes a top plate 11, a bottom plate 12, and a base frame body 13. The top plate 11 and the bottom plate 12 are respectively arranged on the upper and lower sides of the base frame body 13. A plurality of top joints are fixed on the top plate 11, a plurality of bottom joints are arranged in the base frame, the top end of any hose 3 is connected to a top joint, the bottom end of any hose 3 is connected to a bottom joint, and the oil distribution shaft 4 is rotatably arranged on the bottom plate 12 and communicates with the bottom joint. Among them, the rotation of the oil distribution shaft 4 drives all the hoses 3 to twist or reset synchronously.

[0068] In this embodiment, by providing a flexible hose 3 to connect the top joint and the bottom joint, and arranging the oil distribution shaft 4 rotatably on the bottom plate 12 and communicating with the bottom joint, in a horizontal machining center, within the range where the exchange table of the horizontal machining center rotates by ±180°, the flexible hose 3 twists, replacing the oil circuit distributor (rotary joint), thereby reducing costs.

[0069] As Figure 1 and Figure 2 shown, the top joint includes an air pipe partition joint 21 and an oil pipe partition joint 22, and the bottom joint includes a straight-through joint 23 and a right-angle rotary pipe joint 24. The straight-through joint 23 is connected to the bottom end of the flexible hose 3 and communicates with the right-angle rotary pipe joint 24.

[0070] As Figure 1 and Figure 2 shown, the overhead fixture pipeline includes a fixed bushing 8 and a bearing 9. The fixed bushing 8 is installed on the bottom plate 12, and the oil distribution shaft 4 is connected through the bearing 9 and a locking nut to achieve the rotation function.

[0071] As Figure 1 and Figure 2 shown, the overhead fixture pipeline further includes a gland 7. The gland 7 is installed on the oil distribution shaft 4 in cooperation with an O-ring to ensure pipeline sealing. The right-angle rotary pipe joint 24 and the straight-through joint 23 are installed on the gland 7. During the rotation of the table exchange, the right-angle rotary pipe joint 24 can meet the requirements of pipeline turning during the exchange process.

[0072] In this embodiment, the base frame is provided with an anti-winding assembly, and the anti-winding assembly is configured to move synchronously with the flexible hose 3 to slacken the flexible hose 3 when the flexible hose 3 is twisted or to tension the flexible hose 3 when the flexible hose 3 is reset.

[0073] In this embodiment, by providing the anti-winding assembly, the slack state of the flexible hose 3 is changed during the twisting or resetting process of the flexible hose 3, thereby avoiding winding of the flexible hose 3.

[0074] In a specific implementation manner, the top plate 11 is configured to be movable relative to the base frame body. When the flexible hose 3 is twisted, the top plate 11 is pulled by the flexible hose 3 to approach the base frame body; when the flexible hose 3 is reset, the top plate 11 is away from the base frame body under a biasing force.

[0075] To achieve the above effects, as Figure 1 and Figure 2 shown, the anti-winding assembly includes a guide rod 51 and an elastic member 52. The lower end of the guide rod 51 is fixed to the base frame body 13, and the other end of the guide rod 51 is slidably arranged with the top plate 11; the elastic member 52 is arranged between the base frame body and the top plate 11, and the elastic member 52 has a biasing force to push the top plate 11 away from the base frame body 13.

[0076] During use, when the hose 3 is twisted, the top plate 11 is pulled down relative to the guide rod 51, thereby providing sufficient length for the twisting of the hose 3. When the hose 3 is reset, the top plate 11 moves upward under the biasing force of the elastic member 52 to pull and tension the hose 3, thereby preventing the hose 3 from being too loose and causing the hose 3 to become entangled. Preferably, the elastic member 52 is a cylindrical spring sleeved on the periphery of the guide rod 51.

[0077] In this embodiment, the cantilever assembly is connected to the oil distribution shaft 4. The cantilever assembly includes a plurality of connected cantilever brackets 61. Any two connected cantilever brackets 61 can rotate in a first plane and a second plane at the connection, and the first plane is perpendicular to the second plane. The cantilever assembly further includes a hinge bracket 62 and a connection assembly. The hinge bracket 62 is at least movably disposed between two cantilever brackets 61, and the hinge bracket 62 rotates with the cantilever bracket 61 at the hinge in the first plane; the connection assembly is connected between the hinge bracket 62 and the cantilever bracket 61, and the hinge bracket 62 and the cantilever bracket 61 rotate in the second plane through the connection assembly.

[0078] A specific embodiment is as Figure 3 and Figure 4 shown. The number of cantilever brackets 61 is set to two. One hinge bracket 62 is hinged at each end of the inner cantilever bracket 61. The hinge bracket 62 can rotate relative to the inner cantilever bracket 61 in a vertical plane through the hinge. One end of the inner cantilever bracket 61 close to the oil distribution shaft 4 is connected to the oil distribution shaft 4 through the connection assembly of the upper hinge bracket 62, so that this hinge bracket 62 can rotate relative to the connection with the oil distribution shaft 4 in a horizontal plane, thereby realizing the rotation of the inner cantilever bracket 61 relative to the oil distribution shaft 4 in the horizontal plane and the vertical plane.

[0079] Similarly, a connection assembly is also provided between the outer cantilever bracket 61 and the inner cantilever bracket 61, so that the outer cantilever bracket 61 can rotate relative to the inner cantilever bracket 61 in the horizontal plane and the vertical plane.

[0080] In this embodiment, as Figure 6 and Figure 7 shown, the other end of the outer cantilever bracket 61 is connected to an external workbench. Through 4 rotating parts (two connection assemblies and two hinge brackets 62), the Z-direction movement stroke of the workbench and the tray lifting stroke in the exchange process (in two mutually perpendicular planes) can be satisfied, and the use of overhead fixture pipelines at different heights can be satisfied.

[0081] In this embodiment, as Figure 4 and Figure 5As shown, the connecting component includes a rotating shaft 63, a fastener 64, and a nylon gasket 65. The rotating shaft 63 has its fastening end sequentially passing through one end where the cantilever bracket 61 and the hinge bracket 62 overlap, and the other end abuts against the cantilever bracket 61 or the hinge bracket 62 at the bottom; the fastener 64 is connected to the fastening end of the rotating shaft 63, and the nylon gasket 65 is arranged between the fastener 64, the hinge bracket 62, the cantilever bracket 61, or the end of the rotating shaft 63.

[0082] For example, when connecting the outer cantilever bracket 61 and the hinge bracket 62 through the connecting component, the fastening end of the rotating shaft 63 sequentially passes through the through holes on the cantilever bracket 61 and the hinge bracket 62 and then connects to the fastener 64, and nylon gaskets 65 are placed between the bottom of the cantilever bracket 61 and the rotating shaft 63, between the cantilever bracket 61 and the hinge bracket 62, and between the hinge bracket 62 and the fastener 64. Among them, the rotating shaft 63 can adopt a bolt, and the fastener 64 adopts a nut.

[0083] In some other embodiments, the number of the cantilever brackets 61 can also be set to more than two, such as three, four, or others.

[0084] Such as Figure 6 and Figure 7 As shown, during use, the overhead fixture pipeline is fixed to the exchange door assembly 10 through the bottom plate 12, and the other end of the outer cantilever bracket 61 is connected to an external workbench.

[0085] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
