It can prevent the leakage or intrusion of liquids (such as coolants, lubricating oils, etc.) and gases (such as air, humid gases, etc.), ensuring the stability of the internal environment of the motor. The motor O-ring is mainly oiled to play a lubricating role and reduce the friction between the O-ring and other parts of the motor. This can prevent the O-ring from being damaged due to excessive friction during the installation process or the operation of the motor, thereby ensuring the sealing effect. At the same time, the oil can prevent the O-ring from aging to a certain extent and extend its service life.

[0003] At present, O-ring oiling is mostly done manually, with high labor input, difficult to control the amount of oiling, and poor oiling uniformity. When using oiling equipment for oiling, most of them can only oil specific types of motors and O-rings, with poor compatibility and difficulty in ensuring the thickness of the oil film.

With the oil absorption capacity of the foam, the excess grease on the O-ring can be absorbed to ensure good oil coating uniformity. At the same time, the model change is simple, ensuring good compatibility and adaptability to different types of O-rings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] Embodiment 1

[0036] Reference Figure 1-5, an O-ring oiling device, comprising a bottom plate 1 and a top plate 2 arranged opposite to each other, wherein the bottom plate 1 and the top plate 2 are fixedly connected by a plurality of slide bars 21, and a stable connection between the bottom plate 1 and the top plate 2 is ensured by the plurality of slide bars 21 to ensure structural stability, and an oiling mechanism 4 is arranged between the bottom plate 1 and the top plate 2; the O-ring mounted on the motor is oiled by the oiling mechanism 4.

[0037] The oiling mechanism 4 includes a motor placement frame 3 for fixing the motor, a plurality of foam boxes 44 radially slidingly arranged at the lower end of the top plate 2, a movable plate 41 arranged to be lifted and lowered outside the foam box 44, and a linkage component arranged between the movable plate 41 and the foam box 44. The foam box 44 is in a fan-shaped ring shape and a foam 45 is inserted therein. When the plurality of foams 4 are assembled, they are in a ring shape matching the O-ring. The foam box 44 is preferably arranged in four pieces to facilitate the assembly of the plurality of foam boxes 44. When the motor O-ring is oiled, the motor output end is placed upside down on the motor placement frame 3. The linkage component is used to drive the foam box 44 to slide in the horizontal direction when the movable plate 41 is raised and lowered, so as to assemble the plurality of foam boxes 44 and oil the O-ring.

[0038] The bottom plate 1 is provided with a lifting cylinder 411 for driving the movable plate 41 to lift and lower. An oil tank 46 is provided at the upper end of the bottom plate 1 corresponding to the outer side of the foam box 44. The oil tank 46 is filled with lubricating oil. A dodge groove for avoiding the oil tank 46 is provided in the middle of the movable plate 41. The lifting cylinder 411 can be vertically fixedly installed below the bottom plate 1. Its telescopic end passes through the bottom plate 1 and is fixedly connected to the movable plate 41. A position sensor for monitoring the position of the movable plate 41 can also be provided on the bottom plate 1 to ensure synchronous monitoring of the stroke position of the movable plate 41. The lubricating oil contained in the oil tank 46 is absorbed by the foam 45. When the O-ring is oiled, the grease base is infiltrated and coated on the O-ring through the extrusion of the foam 45 and the O-ring. After the oiling is completed, the foam 45 is separated from the O-ring. At this time, the foam 45 can absorb the excess grease on the O-ring to ensure that the amount of grease on the O-ring is appropriate and uniform, to avoid grease dripping, and to ensure a good coating effect.

[0039] The ring oiling method using the above oiling equipment comprises the following steps:

[0040] S1, place the motor with the O-ring inverted on the motor placement rack 3, and keep the O-ring position matched with the foam 45;

[0041] S2, start the lifting cylinder 411 to extend and drive the movable plate 41 to rise, and cooperate with the linkage assembly to drive the multiple foam boxes 44 to slide inward and assemble;

[0042] S3, when the multiple foam boxes 44 are assembled, the inner side of the foam 45 contacts the O-ring, and the O-ring is infiltrated and oiled through the foam 45;

[0043] S4, the lifting cylinder 411 is reset to drive the movable plate 41 to descend, and cooperates with the linkage assembly to drive the outer side of the foam box 44 to slide, and the foam 45 is separated from the O-ring, and at the same time, excess grease is absorbed;

[0044] S5, the foam 45 is used to replenish grease in the oil tank 46, and the motor is removed to complete the oiling of the O-ring.

[0045] In this embodiment, the lifting cylinder 411 cooperates with the linkage assembly to drive the foam box 44 to slide in the horizontal direction. When the foam box 44 slides inward and assembles, the foam 45 contacts and squeezes the O-ring, and the overflowing grease coats the O-ring. When the foam box 44 is separated, the foam 45 is separated from the O-ring and restored to absorb the excess grease on the O-ring, effectively ensuring the uniform oiling of the O-ring, and the appropriate amount of lubricating oil is ensured by the absorption performance of the foam on the lubricating oil, and the oiling quality is guaranteed. Avoid excessive oil after oiling, which causes the lubricating oil to drip and affect the working environment, and ensure the cleanliness of the working environment. The entire oiling process can realize automatic oiling, and when the lubricating oil in the oil tank 46 is insufficient, the oil can be replenished, which saves labor costs to a great extent.

[0046] Embodiment 2

[0047] Reference Figure 1-4 In this embodiment, it is basically the same as the first embodiment, and is more optimized in that the linkage assembly includes a slide rail 43 fixedly installed at the lower end of the top plate 2, a slider 431 slidably installed on the slide rail 43, and a linkage rod 42 rotatably connected between the slider 431 and the movable plate 41. When the lifting cylinder 411 drives the movable plate 41 to rise, the distance between the movable plate 41 and the slider 431 installed on the top plate 2 is shortened, and the multiple linkage rods 42 are squeezed to drive the slider 431 to slide inward, thereby driving the multiple foam boxes 44 to slide inward, so that the foam 45 is spliced ​​and squeezed by the O-ring, and the grease in the foam 45 is squeezed out to wet and coat the O-ring. Through the design of the linkage assembly, the synchronous sliding of the multiple foam boxes 44 is guaranteed, and the uniform oiling effect on the O-ring is guaranteed.

[0048] In this embodiment, Figure 1-4 As shown, a plurality of the slide bars 21 pass through the movable plate 41 and are slidably connected thereto. The sliding connection between the plurality of slide bars 21 and the movable plate 41 ensures the stable lifting of the movable plate 41 and ensures a good synchronization effect on the linkage assembly. A stabilizing rod 412 is vertically fixedly installed on the movable plate 41, and the upper end of the stabilizing rod 412 passes through the top plate 2 and is provided with a limiting end. A plurality of limiting rods 413 are also vertically inserted on the movable plate 41. The movable plate 41 is limited by the stabilizing rod 412 to improve the stability of the movable plate 41 when it is lifted and slid, and the limiting end is used to limit the movable plate 41 to control the stroke of the slider 431, and the stroke of the slider 431 is further controlled by the design of the limiting rod 413.

[0049] In this embodiment, Figure 1-4 As shown, the bottom plate 1 is provided with an oil tank pad for placing the oil tank 46, and a liquid level sensor 461 is fixedly installed in the oil tank 46. The lubricating oil level in the oil tank 46 is detected by the liquid level sensor 461, so that the lubricating oil can be replenished in time when the oil is reduced, so as to avoid the separation of the liquid surface from the foam 45 due to too little oil, which affects the foam 45 to absorb the lubricating oil, and ensure the stable oiling effect on the O-ring.

[0050] Embodiment 3

[0051] Reference Figure 1-5 In this embodiment, the embodiment is basically the same as the first embodiment, and is more optimized in that the upper end of the foam box 44 is connected to a cantilever 441, and the cantilever 441 is fixedly mounted on the slider 431. The design of the cantilever 441 facilitates the replacement of the corresponding foam box 44 and the foam 45 when lubricating motors of different models and O-rings of different models, thereby ensuring the good adaptability of the lubricating equipment to O-rings of different models.

[0052] In this embodiment, Figure 1-5 As shown, the foam box 44 is provided with a foam bin 442 for placing the foam 45, and when the foam 45 is inserted in the foam bin 442, the corresponding O-ring at the upper end is exposed, and oil holes 443 are evenly opened on the side wall of the foam bin 442. The design of the foam bin 442 facilitates replacement of the foam 45 when it is worn, and the exposed part of the foam 45 when inserted contacts the O-ring, ensuring the full contact effect between the foam 45 and the O-ring, and ensuring the oiling effect. The design of the oil holes 443 facilitates the oil to enter the foam bin 442 and fully contact with the foam 45, so that the foam 45 can absorb and replenish the oil.

[0053] Through the convenient replacement setting of the oil tank 46 and the foam box 44, when the type of lubricating oil needs to be changed, it is sufficient to replace the oil tank 46, the foam box 44 and the foam 45. The changeover is convenient and the cost of changeover is low, thereby ensuring good compatibility with different types of lubricating oils and changeover efficiency.

[0054] Embodiment 4

[0055] Reference Figure 1-4 In this embodiment, it is basically the same as the first embodiment, and is more optimized in that a plurality of the upper ends of the slide bars 21 are connected to a crossbeam 22, and the motor placement frame 3 is fixedly mounted on the crossbeam 22. The motor placement frame 3 is L-shaped and a positioning pin 31 is provided on the inner side of the motor placement frame 3 corresponding to the motor mounting hole. The strength of the slide bars 21 is improved by the crossbeam 22 to ensure the overall structural strength of the oiling equipment. The motor is placed and fixed by the motor placement frame 3 in cooperation with the positioning pin 31 to ensure the stability of the motor during oiling. For motors of different models, the corresponding motor placement frame 3 can be used to ensure the adaptability and compatibility of the oiling equipment.

[0056] In this embodiment, Figure 1-4 As shown, a plurality of fixing sleeves 23 are embedded on the top plate 2, and the fixing sleeves 23 are fixedly sleeved on the slide bar 21. By installing the top plate 2 on the slide bar 21 through the fixing sleeves 23, the distance between the top plate 2 and the bottom plate 1 can be adjusted, so that the stroke of the linkage rod 42, the placement position of the motor, etc. can be adjusted according to the oiling requirements of different types of motors, and the adaptability of the oiling equipment can be further improved.
