DETAILED DESCRIPTION

[0022] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0023] In the present disclosure, unless otherwise stated, the directional words used, such as "inside" and "outside", refer to the outline of the part itself. In addition, it should be noted that the terms used, such as "first" and "second", are used to distinguish one element from another, and do not have order and importance. In addition, in the description with reference to the drawings, the same mark in different drawings represents the same element.

[0024] like Figure 1-Figure 3 As shown, the present disclosure provides a sealing ring oiling device, comprising: a support 1, a receiving groove 2 opened in a vertical direction is provided on the support 1, the receiving groove 2 is used to accommodate the sealing ring 3, and an oiling mechanism 4 is also provided on the support 1, the oiling mechanism 4 includes a first oil channel 41 and a second oil channel 42, a first oil outlet 411 of the first oil channel 41 is arranged on the first side wall 21 of the receiving groove 2 and is used to oil the outer side of the sealing ring 3, and a second oil outlet 421 of the second oil channel 42 is arranged on the second side wall 22 of the receiving groove 2 opposite to the first side wall 21 and is used to oil the inner side of the sealing ring 3.

[0025] Through the above technical scheme, the sealing ring oiling device accommodates the sealing ring 3 through the vertically open accommodating groove 2 on the support 1, so that the sealing ring 3 can be placed horizontally in the accommodating groove 2, and the outer side of the sealing ring 3 is oiled through the first oil outlet 411 of the first oil channel 41 of the oiling mechanism 4 on the support 1, and the inner side of the sealing ring 3 is oiled through the second oil outlet 421 of the first oil channel 41, so that the inner and outer sides of the horizontally placed sealing ring 3 can be evenly oiled. When the sealing ring 3 needs to be installed in conjunction with the cylinder body, the oiled sealing ring 3 can be pressed into the installation position of the cylinder body by a manipulator. In this way, the problem of lack of oil in the upper part of the installation position of the sealing ring 3 or the cylinder body due to vertical oiling in the related technology is solved, oil leakage accidents are avoided, and product quality is improved.

[0026] In order to facilitate the oiling of the outer side and the inner side of the sealing ring 3, in some practicable embodiments, the first oil passage 41 and the second oil passage 42 are independently arranged, so that part of the lubricating oil can be applied to the outer side of the sealing ring 3 through the first oil passage 41, and part of the lubricating oil can be applied to the inner side of the sealing ring 3 through the second oil passage 42. By arranging the two oil passages independently, it is possible to avoid the lubricating oil entering the first oil passage 41 and the second oil passage 42 from interfering with each other, thereby ensuring that there is enough lubricating oil to apply oil to the outer side and the inner side of the sealing ring 3 respectively. In addition, by arranging the first oil passage 41 and the second oil passage 42 independently, it is possible to make the first oil passage 41 and the second oil passage 42 apply oil to the outer side and the inner side of the sealing ring 3 under different process conditions, for example, the pressure and flow rate of the first oil passage 41 and the second oil passage 42 can be different.

[0027] In order to evenly apply oil to the outer side and the inner side of the sealing ring 3, in some practicable embodiments, there are multiple first oil outlets 411, and the multiple first oil outlets 411 are arranged at circumferential intervals around the rotation centerline of the accommodating groove 2; there are multiple second oil outlets 421, and the multiple second oil outlets 421 are arranged at circumferential intervals around the rotation centerline of the accommodating groove 2. For example, there are sixty first oil outlets 411, seventy-two second oil outlets 421, and the number of first oil outlets 411 and second oil outlets 421 is A small hole with a diameter of one millimeter, so that when the first oil channel 41 is injected with lubricating oil under a first pressure, the lubricating oil can flow out through sixty first oil outlets 411 circumferentially spaced around the rotation center line of the accommodating groove 2 and be smeared on the outside of the sealing ring 3. Similarly, when the second oil channel 42 is injected with lubricating oil under a second pressure, the lubricating oil can flow out through seventy-two second oil outlets 421 and be smeared on the inside of the sealing ring 3, wherein the first pressure and the second pressure can be selected to be the same or different according to the specific working conditions.

[0028] In order to further evenly apply oil to the outside and inside of the sealing ring 3, in some practicable ways, the plurality of first oil outlets 411 and the plurality of second oil outlets 421 are arranged at equal angles around the circumference of the rotation centerline of the accommodating groove 2. For example, the number of the first oil outlets 411 is sixty, and the number of the second oil outlets 421 is seventy-two, and the first oil outlets 411 and the second oil outlets 421 are evenly arranged at equal angles along the circumference of the rotation centerline of the accommodating groove 2, respectively, so that the lubricating oil passing through the first oil outlets 411 and the lubricating oil passing through the second oil outlets 421 can be more evenly applied to the outside and inside of the sealing ring 3.

[0029] In order to facilitate the lubricating oil entering the first oil channel 41 to be applied to the outer side of the sealing ring 3, in some feasible methods, the first oil channel 41 includes a first oil inlet pipeline 412, a first connecting pipeline 413 and a first oil outlet pipeline 414. The first oil inlet pipeline 412 is arranged at the center of the support 1 and extends in the vertical direction. There are multiple first connecting pipelines 413 and they are arranged at equal angles along the circumference of the central axis of the first oil inlet pipeline 412. One end of the first connecting pipeline 413 is connected to the first oil inlet pipeline 412, and the other end is connected to the first oil outlet pipeline 414. The outer outlet of the first oil outlet pipeline 414 forms a first oil outlet 411, so that the lubricating oil passing through the first oil inlet pipeline 412 enters the first oil outlet pipeline 414 through the first connecting pipeline 413 and flows out through the first oil outlet 411 formed by the outer outlet of the first oil outlet pipeline 414 to apply to the outer side of the sealing ring 3.

[0030] It is understandable that the first oil inlet pipeline 412 , the first connecting pipeline 413 and the first oil outlet pipeline 414 may be separate steel pipes, or may be inner cavity oil pipelines formed on the support 1 .

[0031] Specifically, the first oil outlet pipeline 414 includes an annular first main pipeline 415 and a plurality of first branch pipelines 416 connected to the first main pipeline 415, and each first oil outlet port 411 corresponds to a first branch pipeline 416. In order to facilitate the lubricating oil discharged from the first oil outlet port 411 to contact the outer side of the sealing ring 3 more evenly, the first branch pipeline 416 includes a first vertical section 417 and a first inclined section 418 connected to the first vertical section 417 and arranged upwardly inclined. The outer outlet of the first inclined section 418 forms the first oil outlet port 411. The first vertical section 417 can facilitate the lubricating oil to enter the first inclined section 418. The setting of the first inclined section 418 can enable the lubricating oil to flow out in an elevation trajectory, so that the lubricating oil can contact the higher point on the outer side of the sealing ring 3. The lubricating oil gradually flows to the lower position of the sealing ring 3 with gravity, thereby covering the entire outer side of the sealing ring 3.

[0032] Similarly, in order to facilitate the lubricating oil entering the second oil channel 42 to be applied to the inner side of the sealing ring 3, the second oil channel 42 includes a second oil inlet pipeline 422, a second connecting pipeline 423 and a second oil outlet pipeline 424. There are two second oil inlet pipelines 422, and the two second oil inlet pipelines 422 are respectively located on both sides of the center of the support 1. The two second oil inlet pipelines 422 are connected to the second oil outlet pipeline 424 through the second connecting pipeline 423, and the outer outlet of the second oil outlet pipeline 424 forms a second oil outlet 421, so that the lubricating oil passing through the second oil inlet pipeline 422 enters the second oil outlet pipeline 424 through the second connecting pipeline 423 and flows out through the second oil outlet 421 formed by the outer outlet of the second oil outlet pipeline 424 to apply to the inner side of the sealing ring 3.

[0033] Specifically, the second oil outlet pipeline 424 includes an annular second main pipeline 425 and a plurality of second branch pipelines 426 connected to the second main pipeline 425, the second branch pipeline 426 includes a second vertical section 427 and an upwardly inclined second inclined section 428 connected to the second vertical section 427, the outer outlet of the second inclined section 428 forms a second oil outlet 421, and the setting of the second inclined section 428 enables the lubricating oil to flow out in a trajectory at an elevation angle, so that the lubricating oil can contact the higher point on the inner side of the sealing ring 3, and the lubricating oil gradually flows to the lower position of the sealing ring 3 with gravity, thereby covering the entire inner side of the sealing ring 3.

[0034] In some practicable embodiments, in order to facilitate the processing of the support 1, the support 1 may include a first support 11 and a second support 12, the first support 11 is provided with a recessed portion 13, and the second support 12 is detachably arranged in the recessed portion 13. For example, the first support 11 and the second support 12 are provided with a plurality of threaded holes arranged opposite to each other, and the second support 12 can be fixedly connected to the recessed portion 13 of the first support 11 by a plurality of fastening screws. The first support 11 and the second support 12 can both be circular stainless steel, and the diameter of the first support 11 is larger than that of the second support 12. A first oil passage 41 is provided on the first support 11, and a second oil passage 42 is provided on the second support 12. The inner side wall of the first support 11 and the outer side wall of the second support 12 form a receiving groove 2. In this way, dividing the support 1 into the first support 11 and the second support 12 can facilitate the processing of the first oil passage 41 and the second oil passage 42.

[0035] In some practicable embodiments, the sealing ring oiling device also includes an oil storage tank 5, a first oil pump 6 and a second oil pump 7. The first oil pump 6 is arranged between the oil storage tank 5 and the first oil channel 41, and the second oil pump 7 is arranged between the oil storage tank 5 and the second oil channel 42. The oil storage tank 5 includes a base and an oil storage cavity, and the oil storage cavity is filled with lubricating oil. The first oil pump 6 and the second oil pump 7 are respectively connected to the oil storage tank 5 through oil pipes, and the output port of the first oil pump 6 is connected to the first oil channel 41, and the output port of the second oil pump 7 is connected to the second oil channel 42. The amount of lubricating oil and the pumping pressure in the first oil channel 41 and the second oil channel 42 are controlled by controlling the opening of the first oil pump 6 and the second oil pump 7, respectively, so that the lubricating oil passing through the first oil channel 41 can be evenly applied to the outside of the sealing ring 3, and the lubricating oil passing through the second oil channel 42 can be evenly applied to the inside of the sealing ring 3, so that the sealing ring 3 can have enough lubricating oil to be installed in coordination with the cylinder body.

[0036] In order to facilitate the support of the sealing ring 3, in some practicable ways, a support block 8 for supporting the sealing ring 3 is provided in the receiving groove 2. The support block 8 may be made of resin material, may be a cylinder, may be in multiple numbers, and may be arranged at intervals along the circumference of the central axis of the receiving groove 2. Preferably, there may be six support blocks 8, and the six support blocks 8 may be arranged at equal angles along the circumference, so that the sealing ring 3 placed on the support blocks 8 can be stably supported. Of course, there may also be two support blocks 8, and the two support blocks 8 may be configured in an arc shape and arranged at intervals along the circumference of the central axis of the receiving groove 2.
