[0038] Please refer to Figure 1 and Figure 3As shown, the oiling device corresponding to a preferred embodiment of the present application comprises: a rotating disc mechanism 100 comprising a rotating disc 110 and a receiving tool 120 arranged on the rotating disc 110, the receiving tool 120 is used for accommodating a pipe body 200 arranged along a vertical direction, an axis of the pipe body 200 does not coincide with a projection of the rotating disc 110 in the vertical direction; an oiling mechanism 300 arranged at an oiling station of the rotating disc 110, the oiling mechanism 300 comprises an oiling member 310, a lifting driving member 320 in driving connection with the oiling member 310, and an oil box 330 for accommodating the oiling member 310; wherein the oil box 330 is located below the rotating disc 110, the lifting driving member 320 is adapted to drive the oiling member 310 to reciprocate along the vertical direction between the rotating disc 110 and the oil box 330, and to insert into or pull out the pipe body 200.

[0039] In the present application, the pipe body 200 is arranged along the vertical direction, and the axis thereof does not coincide with the projection of the rotating disc 110 in the vertical direction, so as to facilitate the lifting driving member 320 to drive the oiling member 310 to insert into or pull out the pipe body 200 from the bottom of the pipe body 200, when the pipe body 200 is oiled, the lubricating oil in the pipe body 200 can flow out from the bottom of the pipe body 200 under the action of gravity, so as not to contaminate the rotating disc mechanism 100, and the axial oiling range of the pipe body 200 is controllable, and the oiling precision is improved; in addition, the oiling mechanism 300 comprises the oil box 330 for accommodating the oiling member 310, when the lifting driving member 320 drives the oiling member 310 to descend, the oiling member 310 can be immersed in the oil box 330, so as to realize wetting of the oiling member 310, by using the above-mentioned mode, the structure is simple, the cost is low, and when the oiling member 310 inserts into the pipe body 200 to oil, the lubricating oil flowing out of the pipe body 200 can fall into the oil box 330, so as to improve the cleanliness and avoid waste.

[0040] Further, with reference to Figure 1 and Figure 2As shown, the plurality of accommodation tools 120 are uniformly arranged along the circumference of the turntable 110. The accommodation tool 120 comprises a base plate 121 arranged on the turntable 110, a clamping jaw 122 arranged on the base plate 121, and a clamping driving element 123 in driving connection with the clamping jaw 122. The clamping jaw 122 extends out of the edge of the turntable 110 along the radial direction of the turntable 110 and is used to clamp the pipe body 200. The clamping driving element 123 is adapted to control the opening or closing of the clamping jaw 122, so as to clamp or release the pipe body 200. The clamping jaw 122 comprises a first clamping block 1221 and a second clamping block 1222 in rotational connection with the base plate 121. The rotational axis direction of the first clamping block 1221 and the second clamping block 1222 is consistent with the axis direction of the turntable 110. The first clamping block 1221 and the second clamping block 1222 have clamping ends and transmission ends opposite to the clamping ends. The clamping ends are located outside the edge of the turntable 110, and the two clamping ends cooperate to clamp the pipe body 200. The clamping driving element 123 is in driving connection with the transmission ends to drive the first clamping block 1221 and the second clamping block 1222 to rotate. The clamping jaw 122 further comprises a first elastic element 1223 connected between the first clamping block 1221 and the second clamping block 1222 to provide a force to keep the clamping jaw 122 in the closed state. The first elastic element 1223 can be a spring, and the two ends of the spring are respectively connected to the first clamping block 1221 and the second clamping block 1222.

[0041] In the embodiment, the clamping driving element 123 is a linear air cylinder arranged along the radial direction of the turntable 110. The base plate 121 movably connects a transmission push block 124, which is arranged close to the transmission end of the clamping jaw 122. The transmission push block 124 is adapted to cooperate with the inclined surfaces of the two transmission ends. The clamping driving element 123 is in driving connection with the transmission push block 124 to drive the transmission push block 124 to move close to or away from the transmission end. By adopting the above structure, the height of the accommodation tool 120 can be effectively reduced, and the space adaptability is improved. When the transmission push block 124 moves close to the clamping jaw 122, it can push the clamping jaw 122 to switch from the closed state to the open state and compress the first elastic element 1223. When the transmission push block 124 moves away from the clamping jaw 122, the clamping jaw 122 can reset under the action of the first elastic element 1223 and remain in the closed state to clamp the pipe body 200.

[0042] Preferably, the number of clamping jaws 122 is at least one to improve the accommodation capacity of each accommodation tool 120. Specifically, the accommodation tool 120 further comprises a mounting plate 125 in driving connection with the output end of the clamping driving element 123. At least one transmission push block 124 is arranged on the mounting plate 125 and corresponds to one clamping jaw 122, so that a single clamping driving element 123 simultaneously drives multiple transmission push blocks 124 to move. In the embodiment, the number of clamping jaws 122 is two, so that each accommodation tool 120 can simultaneously clamp two pipe bodies 200.

[0043] Preferably, a second elastic member 126 is arranged between the transmission push block 124 and the mounting plate 125 to provide a buffering force when the transmission push block 124 moves towards the clamping jaw 122, preventing damage to the clamping jaw 122. The second elastic member 126 can be a spring in particular, with two ends respectively connected to the transmission push block 124 and the mounting plate 125.

[0044] In an embodiment, the clamping drive 123 can be fixedly connected to the mounting plate 125. Preferably, in this embodiment, the clamping drive 123 is detachably connected to the mounting plate 125, the rotating disc 110 is annular in structure, and the rotating disc mechanism 100 is provided with a relatively fixed mounting disc 130 in the middle, and the clamping drive 123 is fixed to the mounting disc 130, thereby avoiding the rotating disc 110 from bearing the clamping drive 123, reducing the load of the rotating disc 110, lowering energy consumption and improving service life. In addition, when part of the workstations of the rotating disc 110 do not need to control the opening or closing of the holding tool 120, the clamping drive 123 can also be reduced in number, and only be arranged at the workstations where the opening or closing of the holding tool 120 is needed.

[0045] In particular, the output end of the clamping drive 123 can be fixedly connected to a hook structure (not shown in the figure), the mounting plate 125 has a first transmission surface facing the clamping jaw 122 and a second transmission surface facing away from the clamping jaw 122, and the hook structure has a first hook surface arranged opposite to the first transmission surface and a second hook surface arranged opposite to the second transmission surface. When the clamping drive 123 is retracted, the first hook surface approaches and contacts the first transmission surface, and drives the mounting plate 125 to move away from the clamping jaw 122, thereby driving the transmission push block 124 to move away from the clamping jaw 122. When the clamping drive 123 is extended, the second hook surface approaches and contacts the second transmission surface, and drives the mounting plate 125 to move towards the clamping jaw 122. When the hook structure is not in contact with the mounting plate 125, the clamping drive 123 is separated from the mounting plate 125, so as to avoid the clamping drive 123 from restricting the rotation of the rotating disc 110. Preferably, in order to avoid the hook structure from restricting the rotation of the rotating disc 110 in the separated state, the above-mentioned surfaces can be arc-shaped surfaces.

[0046] Indeed, a return spring can also be arranged on the mounting plate 125, and the second hook surface can be removed. When the clamping drive 123 is retracted, the first hook surface approaches and contacts the first transmission surface, and drives the mounting plate 125 to move away from the clamping jaw 122, thereby driving the transmission push block 124 to move away from the clamping jaw 122, at which time the return spring is compressed. When the clamping drive 123 is extended, the mounting plate 125 is driven to return to the original position by the return spring and moves towards the clamping jaw 122.

[0047] Further, with reference to Figures 3 to 5As shown, the oiling member 310 is a rod-shaped structure that is adapted to the inner profile of the pipe body 200, and when the holding tool 120 is located at the oiling station, the pipe body 200 on the holding tool 120 is coaxially arranged with the oiling member 310. The oiling member 310 is inwardly recessed at the top thereof to form an oil storage hole 311, and lubricating oil can enter the oil storage hole 311 from the top of the oiling member 310. The oiling member 310 is provided with a plurality of oil outlets 312 that are in communication with the oil storage hole 311 and are arranged at intervals along the axial and circumferential directions of the oiling member 310. With the above structure, the oil storage hole 311 can effectively attach lubricating oil to the oiling member 310, and when the oiling member 310 moves towards the pipe body 200, the oiling member 310 still has a large amount of lubricating oil to sufficiently coat the inner wall of the pipe body 200.

[0048] The oiling mechanism 300 includes a base 340, and the lifting driving member 320 and the oil box 330 are arranged on the base 340. The lifting driving member 320 is specifically a lifting cylinder, and the oiling member 310 is fixedly connected to the output end of the lifting driving member 320 through a mounting bracket 350. Since the holding tool 120 is provided with a plurality of clamping jaws 122 for clamping the pipe body 200, correspondingly, the number of the oiling members 310 is also multiple and corresponds to the plurality of clamping jaws 122 one by one.

[0049] The oil box 330 includes an oil groove 331 and a tank body 332 accommodated in the oil groove 331, and the tank body 332 corresponds to the oiling member 310 one by one. The oil groove 331 and the tank body 332 are both open at the top, the tank body 332 is used for storing lubricating oil, and the oiling member 310 can enter the tank body 332 from the top of the tank body 332 and be wetted.

[0050] With the above structure, the oil groove 331 has a large opening and can reliably collect the lubricating oil that falls during the lifting of the oiling member 310 and the lubricating oil that falls after the pipe body 200 is coated with oil, while the tank body 332 has a small volume and opening and can ensure that the oiling member 310 is completely wetted with a small capacity and also can reduce the emission of lubricating oil from the tank body 332 to avoid waste.

[0051] The bottom of the tank body 332 is externally connected with an oil inlet connector 333 to input lubricating oil into the tank body 332. The number of the oil inlet connector 333 can be one, and the different tank bodies 332 can be in communication with each other, or the bottom of each tank body 332 is provided with an oil inlet connector 333. Preferably, the bottom of the oil groove 331 can be provided with a collection port (not shown in the figure), and the lubricating oil collected in the oil groove 331 can flow out through the collection port and be collected to be reused to avoid waste.

[0052] The working process of the present application is as follows: the rotating disc 110 drives the containing tool 120 to rotate to the feeding station, the clamping driving member 123 extends and pushes the transmission push block 124 to move to the clamping jaw 122, the first clamping block 1221 and the second clamping block 1222 are rotated under the pushing force and make the two clamping ends far away from each other, at this time, the clamping jaw 122 is in the open state; the feeding device (not shown in the figure) feeds the pipe body 200 to the space between the first clamping block 1221 and the second clamping block 1222, the clamping driving member 123 is retracted, the first clamping block 1221 and the second clamping block 1222 are reset under the action of the first elastic member 1223 to reset to the closed state and clamp the pipe body 200; the rotating disc 110 drives the containing tool 120 to rotate to the oiling station, the lifting driving member 320 drives the oiling member 310 to rise to make the oiling member 310 leave the oil box 330 and insert into the pipe body 200 along the vertical direction from the bottom of the pipe body 200, in this process, the lubricating oil in the oiling member 310 / or the pipe body 200 falling under the gravity can fall into the oil box 330; then the lifting driving member 320 drives the oiling member 310 to fall back to the oil box 330, the rotating disc 110 drives the containing tool 120 to continue to rotate to the next station.

[0053] The above description is only the embodiment of the present application, and does not limit the patent scope of the present application, and any equivalent structure or equivalent process transformation using the content of the present application specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection scope of the present application.
