DETAILED DESCRIPTION

[0034] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0036] In addition, the terms "horizontal", "vertical" and the like do not mean that the components are required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0037] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" 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 a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] The traditional manual oiling method mainly relies on manual application with fingers wearing gloves or brushes dipped in oil. This method is not only inefficient, but also difficult to ensure the uniformity and consistency of oiling, which affects product quality. In addition, manual oiling also increases the labor intensity of operators and reduces work efficiency.

[0039] At present, there are some automatic oiling devices on the market, but these devices are usually complex in structure, involving multiple valve bodies, cylinders and other components, resulting in high costs. At the same time, due to the high degree of integration of these devices, they usually cannot be disassembled for manual operation, which limits their flexibility of use.

[0040] In view of the above technical problems, an embodiment of the present application provides a hub bearing riveting interface oiling mechanism, including an oil storage component, the oil storage component includes an oil tank 1, the bottom end face of the oil tank 1 is connected to an oil guide pipe 2, the inner side of the oil guide pipe 2 is sleeved with a middle cavity tube 3, there is a gap between the middle cavity tube 3 and the oil guide pipe 2, one side of the middle cavity tube 3 is provided with an oil guide hole 1 3a, the lower end of the middle cavity tube 3 is sealed and fixed to the oil guide pipe 2; including an oil outlet component, the oil outlet component includes a piston tube 4, an oil outlet cover 5, oil absorbing cotton 6 and a pressure cover 7, the upper part of the piston tube 4 is movably arranged in the corresponding middle cavity tube 3, the upper end of the piston tube 4 is closed, and its lower end is connected to the oil outlet cover 5, one side of the piston tube 4 is provided with an oil guide hole 2 4a matching the oil guide hole 1 3a; the oil absorbing cotton 6 is arranged in the oil outlet cover 5, the lower end of the oil outlet cover 5 is provided with an opening, the pressure cover 7 covers the opening, and the middle part of the pressure cover 7 is provided with an oil application port 7a.

[0041] The hub bearing riveting interface oiling mechanism realizes the oiling function through the coordinated work of the oil storage component and the oil outlet component. Before the oiling starts, the oil guide hole 1 3a and the oil guide hole 2 4a are in a staggered state, ensuring that the oil guide pipe 2 and the piston tube 4 are not connected, preventing the leakage of lubricating oil. When the hub bearing is transported to the bottom of the oiling mechanism, the oiling mechanism descends, allowing the hub bearing riveting interface to pass through the oiling port 7a into the oil outlet cover 5. As the oiling mechanism continues to descend, the piston tube 4 retracts into the oil guide pipe 2 until the oil guide hole 1 3a coincides with the oil guide hole 2 4a, and the lubricating oil path is connected. At this time, the lubricating oil in the oil tank 1 flows into the oil outlet cover 5 through the oil guide pipe 2, the oil guide hole 1 3a, the oil guide hole 2 4a and the piston tube 4 in turn, and is adsorbed by the oil-absorbing cotton 6 and smeared on the hub bearing riveting interface. After the oiling is completed, the oil storage assembly rises, the oiling port 7a leaves the hub bearing, and the piston tube 4 moves downward to make the oil guide hole 1 3a and the oil guide hole 2 4a staggered again, interrupting the flow of lubricating oil and preventing oil leakage.

[0042] The hub bearing riveting interface oiling mechanism realizes the automatic control of the oiling process and improves the oiling efficiency through the combined design of the oil storage component and the oil outlet component.

[0043] The oiling process is controlled by the up and down movement of the piston tube 4, which has a simple structure and is easy to operate, and reduces the use of complex driving devices such as valve bodies and cylinders in traditional oiling devices, thereby reducing the cost of the equipment.

[0044] The oiling mechanism is easy to install and disassemble, and can not only be integrated on automated equipment for use, but can also be disassembled for manual operation when needed, which greatly improves the oiling efficiency and avoids the problem of low efficiency in traditional manual oiling methods.

[0045] In some embodiments, the oiling mechanism includes a first reset assembly, which includes a mounting cylinder 8, a spring 9, a push rod 10 and a middle plate 11; a sealing cover 12 is provided at the upper end of the mounting cylinder 8, and a lower end thereof is sealed and fixed on the inner side of the bottom plate of the oil tank 1; the spring 9 is arranged inside the mounting cylinder 8, and the push rod 10 vertically penetrates the bottom plate of the oil tank 1, and the upper end of the push rod 10 extends into the mounting cylinder 8 and abuts against the lower end of the spring 9, and the lower end of the push rod 10 is fixedly connected to the middle plate 11; one side of the middle plate 11 is fixedly connected to the piston tube 4.

[0046] The oiling mechanism realizes the automatic reset function of the piston tube 4 through the additional first reset component. The reset component includes a mounting cylinder 8, a spring 9, a push rod 10 and a middle plate 11. When the oiling mechanism descends to perform the oiling operation, the middle plate 11 moves upward and drives the push rod 10 upward, thereby compressing the spring 9 in the mounting cylinder 8. At this time, the spring 9 stores elastic potential energy. After the oiling is completed, the oil storage component rises, and the spring 9 releases the stored energy under the action of its own elastic force, pushing the push rod 10 to move downward. The movement of the push rod 10 then drives the middle plate 11 and the piston tube 4 fixedly connected thereto to move downward together, so that the oil guide hole 1 3a and the oil guide hole 2 4a are re-staggered, thereby cutting off the flow path of the lubricating oil, interrupting the oiling process, and effectively preventing oil leakage. The design of the first reset component ensures that the piston tube 4 can automatically and quickly reset after the oiling is completed, without the need for additional control devices or manual intervention, thereby improving work efficiency.

[0047] In some embodiments, the cover 12 is threadedly connected to the mounting cylinder 8, a pressure head is provided at the upper end of the push rod 10, and the push rod 10 abuts against the lower end of the spring 9 through its pressure head. The push rod 10 passes through the middle plate 11 and is threadedly connected with a nut 13, which is used to fix the push rod 10 to the middle plate 11.

[0048] Through the above structural design, the assembly process of the first reset assembly is to first pass the push rod 10 through the bottom plate of the oil tank 1 from the installation cylinder 8, then install the spring 9, then tighten the cover 12, and then lock and fix the lower end of the push rod 10 and the middle plate 11 through the nut 13. Through the threaded connection design between the cover 12 and the installation cylinder 8, and the nut 13 fixing method between the push rod 10 and the middle plate 11, the assembly and disassembly of the first reset assembly becomes more convenient, which is conducive to later maintenance and replacement.

[0049] In some embodiments, two oil guide pipes 2 are connected to the bottom end surface of the oil tank 1, and the oil outlet assembly includes two piston tubes 4. The upper parts of the two piston tubes 4 are movably arranged in the corresponding oil guide pipes 2, and the lower ends of the two piston tubes 4 are connected to the oil outlet cover 5.

[0050] The coordinated use of the two oil guide pipes 2 and the piston pipe 4 increases the drainage volume of the lubricating oil and improves the oiling efficiency, so that a larger area of ​​oiling can be completed in a shorter time. The two pistons are connected to the oil outlet cover 5, and through the dispersion effect of the oil outlet cover 5, the lubricating oil can be more evenly distributed at the target position when it flows out, thereby improving the quality and effect of oiling.

[0051] On the other hand, an embodiment of the present application provides a hub bearing riveting interface oiling device, comprising the above-mentioned oiling structure, and also comprising a frame 14 and a lifting drive mechanism, wherein the frame 14 is provided with a vertical oil tank guide rail, and one side of the oil tank 1 can be lifted and connected to the frame 14 via the oil tank guide rail, and the lifting drive mechanism is connected to the oil tank 1 for driving it to lift and lower to achieve automatic oiling.

[0052] When oiling is required, the lifting drive mechanism starts, driving the oil tank 1 down to a suitable position, and the oiling structure starts to work, applying lubricating oil to the riveted interface of the hub bearing; after the oiling is completed, the lifting drive mechanism starts again to raise the oil tank 1 for the next round of operation or maintenance. By setting up the lifting drive mechanism, the automation of the oiling process is realized.

[0053] In some embodiments, the lifting drive mechanism includes two symmetrically arranged linked lifting components, which include a rack guide 15, a rack 16, a connecting rod 17, a gear 18 and a baffle 19; the rack guide 15 is laterally fixedly connected to the frame 14, and a rack groove is provided in the rack guide 15. The rack 16 can be laterally movably arranged in the rack groove. The gear 18 is horizontally rotatably connected to the frame 14 and meshes with the rack 16. One end of the baffle 19 is connected to the middle part of the gear 18 and rotates horizontally with the gear 18. The other end of the baffle 19 is suspended on the conveying line of the wheel hub bearing; one end of the connecting rod 17 is hingedly connected to the oil tank 1, and the other end is hingedly connected to the rack 16.

[0054] With the above structural design, when the wheel hub bearing moves on the conveyor line, it will hit the stopper 19 and drive it to move. The movement of the stopper 19 drives the gear 18 to rotate, and the rotation of the gear 18 drives the rack 16 to move laterally in the rack groove. The displacement of the rack 16 is transmitted to the oil tank 1 through the connecting rod 17, causing the oil tank 1 to descend, thus realizing the linkage between the displacement of the wheel hub bearing and the lifting and lowering of the oil tank 1.

[0055] The displacement of the wheel hub bearing itself is used as a power source to drive the oil tank 1 to rise and fall, thereby realizing the function of automatic oiling. This linkage mechanism eliminates the need for an additional drive mechanism, saves energy, and improves the reliability of the equipment. At the same time, a symmetrically arranged linkage lifting component is used, making the entire lifting drive mechanism more balanced and stable.

[0056] In some embodiments, the rack guide rail 15 is provided with a first guide groove 15 a extending transversely, the rack 16 is connected with a guide block 18 , the guide block 18 is slidably disposed in the first guide groove 15 a , and the connecting rod 17 is hingedly connected to the guide block 18 .

[0057] The connecting rod 17 is hingedly connected to the guide block 18. When the rack 16 moves laterally along the first guide groove 15a driven by the gear 18, the connecting rod 17 will swing accordingly and be hingedly connected to the oil tank at its other end, thereby driving the oil tank to move up and down, thereby achieving a smooth transition from the lateral movement of the rack 16 to the lifting of the oil tank.

[0058] In some embodiments, the oiling device includes a second reset assembly, which includes a threaded rod 19, an adjusting block 20 and a reset spring 21; the threaded rod 19 is connected to a support plate at one end of the rack guide rail 15 along a transverse rotation, and a portion of the adjusting block 20 is threadedly connected to the threaded rod 19; the rack guide rail 15 is provided with a second guide groove extending transversely, a portion of the adjusting block 20 passes through the second guide groove and is arranged in the rack groove, the portion of the adjusting block 20 located in the rack groove is connected to the reset spring 21, and the reset spring 21 is connected to the rack 16.

[0059] When the wheel hub bearing moves on the conveyor line and drives the stop bar 19 to move, the gear 18 rotates accordingly and drives the rack 16 to move in the rack guide 15. In this process, the return spring 21 is stretched and stores elastic potential energy. When the wheel hub bearing passes the stop bar 19, that is, when no external force is applied to the stop bar 19, the return spring 21 releases the stored elastic potential energy and provides elastic force to enable the rack 16 to return to its initial position along the rack guide 15. The recovery movement of the rack 16 then drives the oil tank 1 to rise to its initial position, thereby realizing the automatic reset function of the entire oiling device.

[0060] By rotating the threaded rod 19, the position of the adjustment block 20 can be moved, thereby flexibly adjusting the stretching amount and stretching strength of the return spring 21, so that the oiling device can adapt to the needs under different working conditions, which can be achieved through simple adjustment.

[0061] In some embodiments, the linkage lifting assembly includes a guide plate 22, which is fixedly mounted on the frame 14. The two guide plates 22 form a hub bearing displacement guide channel, and one end of the blocking rod 19 is suspended in the guide channel.

[0062] The design of the guide channel ensures that the wheel hub bearing can move stably along the predetermined path when moving on the conveyor line, avoiding the deflection or shaking of the wheel hub bearing during movement. One end of the blocking rod 19 is suspended in this guide channel. When the wheel hub bearing passes through, it will naturally contact the blocking rod 19 and drive it to move. The movement of the blocking rod 19 then triggers the operation of the linkage lifting component to realize the lifting and lowering of the oil tank, so that a close linkage relationship is formed between the displacement of the wheel hub bearing and the lifting and lowering of the oil tank.

[0063] Another aspect of the embodiment of the present application provides an oiling method for a hub bearing riveting interface oiling mechanism, comprising the following steps:

[0064] S1. The wheel hub bearing is transported on the transmission line to the bottom of the oiling mechanism with the riveted interface facing upward;

[0065] S2, the oiling mechanism descends, so that the hub bearing riveting interface faces upward through the oiling port 7a and enters the oil outlet cover 5;

[0066] S3, the oiling mechanism continues to descend, and the piston tube 4 retracts into the oil guide tube 2 until the oil guide hole 1 coincides with the oil guide hole 2, so that the piston tube is connected with the oil guide tube;

[0067] S4. The lubricating oil in the oil tank flows into the oil outlet cover 5 through the oil guide pipe 2, the oil guide hole 1 3a, the oil guide hole 2 4a, and the piston tube 4 to lubricate the riveting interface of the wheel hub bearing.

[0068] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
