Automatic bearing oiling machine

Abstract

This utility model relates to the field of oiling machine technology, specifically to an automatic bearing oiling machine. It includes a fixed plate with a placement groove in the center. A movable ring is movably connected within the placement groove, and an oil storage pipe is located on the upper side of the movable ring. Oil outlet holes are evenly distributed on the outer wall of the movable ring in a ring-like structure. It also includes an overlapping ring movably connected inside the movable ring, with multiple through holes evenly distributed on its circumferential outer wall. When the lower outer wall of the overlapping ring contacts the outer wall of the overlapping groove at the bottom of the placement groove, the through holes align with the oil outlet holes, and oil from the oil storage pipe overflows from the oil outlet holes and coats the bearing. Through the elastic connection between the movable ring and the overlapping ring, the relative movement between them during the oiling process enables automatic oil addition. Furthermore, in conjunction with the movable column and elastic membrane, the lubricating oil can be pressurized before oiling, ensuring that the lubricating oil is more comprehensively coated on the internal bearing balls.

Description

Technical Field

[0001] This utility model relates to the field of oiling machine technology, and in particular to an automatic bearing oiling machine. Background Technology

[0002] An automatic bearing oiling machine is a device that injects lubricating oil into the inside of a bearing. The lubricating oil inside the bearing plays a lubricating role, ensuring that the friction of the bearing rotation is reduced, and also extending the service life of the bearing. Therefore, after a certain period of use, a certain amount of lubricating oil needs to be added to the inside of the bearing. When using existing oiling machines, they can only simply inject a certain amount of lubricating oil into the bearing, relying on the fluidity of the lubricating oil to achieve uniform coating of the lubricating oil inside the bearing. The oiling efficiency is low. In view of this, we propose an automatic bearing oiling machine. Summary of the Invention

[0003] This invention addresses the shortcomings of existing technologies by providing an automatic bearing oiling machine. It effectively solves the problem that existing oiling machines can only inject a certain amount of lubricating oil into the bearing and rely on the fluidity of the lubricating oil to achieve uniform coating inside the bearing, resulting in low oiling efficiency.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0005] An automatic bearing oiling machine includes a fixed plate, a placement groove is provided in the middle of the fixed plate, a movable ring is movably connected in the placement groove, and an oil storage pipe is provided on the upper side of the movable ring.

[0006] It also includes an oil outlet hole that is uniformly opened in a ring shape on the outer wall of the moving ring, and a lap ring that is movably connected inside the moving ring. Multiple through holes are uniformly opened on the outer circumference of the lap ring. When the outer wall of the lower end of the lap ring contacts the outer wall of the lap groove opened on the bottom surface of the placement groove, the through hole is aligned with the oil outlet hole, and the oil in the oil storage pipe will overflow from the oil outlet hole and be coated on the bearing.

[0007] Preferably, the oil storage pipe has an oil storage tank inside, which is connected to the external oil circuit through a connecting pipe; and a cavity is formed in the movable ring, with the overlapping ring elastically connected to the inner wall of the cavity by a spring. When no oil is injected, the spring is in its original state, and the oil storage tank is connected to the cavity.

[0008] Preferably, a filter membrane is provided on the top surface of the overlapping ring. The filter membrane is arranged in a circular shape. A sealing component is fixedly installed in the middle of the top surface of the overlapping ring. The size of the sealing component is adapted to the size of the oil storage tank. A blocking ring is also fixedly provided on the top surface of the overlapping ring. When no oil is injected, the spring is in its original state. At this time, the blocking ring can block the oil outlet. A column is also provided at the lower end of the overlapping ring. A movable column is movably connected in the column.

[0009] Preferably, the overlapping ring has a cavity inside, and the through holes are evenly distributed on the inner wall of the cavity in a ring structure. The column has a movable groove inside, the movable column is movably connected in the movable groove, and an arc-shaped block is fixedly installed at the upper end of the movable column.

[0010] Preferably, it also includes an elastic membrane disposed on the inner wall of the bottom surface of the chamber. During oil injection, the top surface of the arc-shaped block contacts the outer wall of the bottom surface of the elastic membrane and squeezes the lubricating oil in the chamber.

[0011] Preferably, a cylindrical component is fixedly connected to the bottom surface of the fixing plate, and an annular groove is formed inside the cylindrical component. A drive ring is rotatably connected to the lower side of the cylindrical component, and a friction ring is provided on the top surface of the drive ring. An arc-shaped groove is formed on the inner wall of the drive ring, and a push rod is inserted into the arc-shaped groove, with the upper end of the push rod extending to the inner wall of the bottom surface of the placement groove.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention utilizes the elastic connection between the movable ring and the overlapping ring to automatically add lubricating oil during the oil injection process by taking advantage of their relative movement. Furthermore, the movable column and elastic membrane can pressurize the lubricating oil before injection, thereby ensuring that the lubricating oil is more comprehensively coated on the internal balls of the bearing.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings.

[0026] The following description is intended to disclose the invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious modifications will be apparent to those skilled in the art. The basic principles of the invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the invention.

[0027] Those skilled in the art should understand that, in the disclosure of this invention, the terms "longitudinal," "lateral," "upper," "lower," "left," "right," "front," "rear," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or position based on the orientation or positional relationship shown in the accompanying drawings. They are merely simplified descriptions for the convenience of describing this invention and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this invention.

[0028] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number. Example

[0029] Please see Figures 1-4As shown, an automatic bearing oiling machine includes a fixed plate 100, a placement groove 101 in the middle of the fixed plate 100, a movable ring 200 movably connected in the placement groove 101, an oil storage pipe 210 on the upper side of the movable ring 200, and oil outlet holes 202 evenly formed in a ring on the outer wall of the movable ring 200. It also includes an overlapping ring 300 movably connected inside the movable ring 200. Multiple through holes 302 are evenly formed on the outer circumferential wall of the overlapping ring 300. When the lower outer wall of the overlapping ring 300 contacts the outer wall of the overlapping groove 103 formed on the bottom surface of the placement groove 101, the through holes 302 align with the oil outlet holes 202, and the oil in the oil storage pipe 210 overflows from the oil outlet holes 202 and coats the bearing. Specifically, in this application, when the bearing needs to be lubricated, the bearing is placed on the inner wall of the placement groove 101, and then an external drive mechanism is used to drive the moving ring 200 and the oil storage pipe 210 to move downward synchronously. Correspondingly, the through hole 302 and the oil outlet hole 202, which were originally misaligned, become aligned. At this time, the oil in the chamber 301 can pass through the through hole 302 and the oil outlet hole 202 and drip directly onto the balls inside the bearing, thereby realizing the addition of bearing lubricating oil.

[0030] When no oil is added, the corresponding moving ring 200 is positioned above the placement groove 101. Specifically, the oil storage pipe 210 has an oil storage groove 211 inside, which is connected to the external oil passage via a connecting pipe 212. Additionally, the cavity 201 within the moving ring 200 has an overlapping ring 300 elastically connected to the inner wall of the cavity 201 via a spring 330. When no oil is added, the spring 330 is in its original position, and the oil storage groove 211 is connected to the cavity 201. In this application, when no oil is added, the overlapping ring 300 and the moving ring 200 are elastically connected via the spring 330, and the through hole 302 and the oil outlet hole 202 are misaligned, with the corresponding oil outlet hole 202 blocked by the blocking ring 310.

[0031] Furthermore, the overlapping ring 300 has a cavity 301 inside, and through holes 302 are evenly distributed in a ring structure on the inner wall of the cavity 301. A filter membrane 340 is provided on the top surface of the overlapping ring 300. The filter membrane 340 is arranged in a circular shape. A sealing member 350 is fixedly installed in the middle of the top surface of the overlapping ring 300. The size of the sealing member 350 is adapted to the size of the oil storage tank 211. A blocking ring 310 is also fixedly provided on the top surface of the overlapping ring 300. When no oil is injected, the spring 330 is in its original state. At this time, the blocking ring 310 can block the oil outlet 202. A column 320 is also provided at the lower end of the overlapping ring 300. A movable column 400 is movably connected inside the column 320. When no oil is added, the sealing element 350 will not block the lower opening of the oil reservoir 211. At this time, the oil in the oil reservoir 211 will flow into the cavity 201 along the top surface of the sealing element 350 and be located above the filter membrane 340. It will then flow into the cavity 301 through the filter membrane 340 in preparation for subsequent oil addition.

[0032] In the oil filling process: Specifically, a movable groove 321 is provided inside the column 320, and the movable column 400 is movably connected within the movable groove 321. An arc-shaped block 410 is fixedly installed at the upper end of the movable column 400. It also includes an elastic membrane 322 disposed on the inner wall of the bottom surface of the chamber 301. During oil filling, the top surface of the arc-shaped block 410 contacts the outer wall of the bottom surface of the elastic membrane 322, squeezing the lubricating oil inside the chamber 301. During oil filling, the bearing is placed inside the placement groove 101. First, the external driving component drives the movable ring 200 to move downward. At this time, the lower outer wall of the movable column 400 will contact the groove wall of the overlapping groove 103, causing the movable column 400 to move upward. The arc-shaped block 410 fixedly connected to the upper side of the movable column 400 will contact the elastic membrane 322, causing the elastic membrane 322 to deform. When the elastic membrane 322 deforms, an elastic force will be applied to the column 320, causing the column 320 and the overlapping ring 300 to move upward. During this process, the through hole 302 and the oil outlet hole 202 gradually change from a misaligned state to an overlapping state. At this time, the oil in the chamber 301 can be squeezed onto the bearing.

[0033] Furthermore, during the aforementioned process, when the oil in the chamber 301 is not discharged from the oil outlet 202, the lubricating oil will be pressurized. At the instant when the through hole 302 coincides with the oil outlet 202, the lubricating oil with a certain pressure will be sprayed toward the balls in the bearing, thereby ensuring the uniformity of the lubricating oil coating.

[0034] Furthermore, in this application, a cylindrical member 110 is fixedly connected to the bottom surface of the fixed plate 100. An annular groove 102 is formed inside the cylindrical member 110. A drive ring 500 is rotatably connected to the lower side of the cylindrical member 110. A friction ring 510 is provided on the top surface of the drive ring 500. An arc-shaped groove 501 is formed on the inner wall of the drive ring 500, and a push rod 520 is inserted into the arc-shaped groove 501, with the upper end of the push rod 520 extending to the inner wall of the bottom surface of the placement groove 101. During the oiling process, since the position of the oil outlet 202 is relatively fixed, to ensure the uniformity of lubricant addition, the drive ring 500 is rotated under the action of an external rotating shaft. The friction between the friction ring 510 and the bearing is used to synchronously rotate the bearing, thereby achieving comprehensive oiling of the bearing and improving oiling efficiency. Furthermore, in this application, the push rod 520 can be used to unload the bearing after oiling.

[0035] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The objectives of the present invention have been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations of the embodiments of the present invention may be made without departing from the stated principles.
