Description

Technical Field

[0001] This utility model relates to the field of lubrication structure technology, and in particular to a self-lubricating component for a pneumatic assembly tool. Background Technology

[0002] Pneumatic assembly tools, as commonly used drive devices in industrial automated assembly processes, rely heavily on their internal transmission components, particularly the lubrication condition between shafts and bearings, for their operational performance and service life. Currently, some pneumatic assembly tools rely on manual periodic lubrication or simple grease seals, resulting in uneven lubrication, low lubrication efficiency, inconvenient operation, and short service life. Furthermore, the lubricating oil cannot be automatically adjusted and supplied according to the actual working conditions of the shaft, easily leading to insufficient lubrication or waste, thus affecting the stability and lifespan of the assembly tool.

[0003] To address this problem, we propose a self-lubricating pneumatic assembly tool component. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a self-lubricating component for pneumatic assembly tools.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a self-lubricating assembly for a pneumatic assembly tool, comprising a shaft, a bearing housing, and a lubrication housing, wherein the bearing housing and the shaft are rotatably connected via a bearing body, and an oil discharge mechanism is provided inside the bearing housing for discharging waste oil;

[0006] The lubrication shell is disposed on the bearing housing, and a self-lubricating mechanism is provided between the lubrication shell and the bearing body. The self-lubricating mechanism is used to perform self-lubrication on the bearing body. There are two sets of self-lubricating mechanisms, which are symmetrically distributed relative to the bearing body.

[0007] Preferably, the self-lubricating mechanism consists of a ring, a wheel frame, a roller, a through hole, a lubricating wheel, an arc-shaped cavity, an arc-shaped block, and a spring. The ring is mounted on the shaft, the wheel frame is mounted on the ring, and the roller is rotatably mounted on the wheel frame.

[0008] Preferably, the arc-shaped cavity is symmetrically formed within the lubrication shell, the lubrication wheel is rotatably disposed within the arc-shaped cavity, the lubrication wheel partially penetrates the lubrication shell, and the wheel surface of the lubrication wheel is in contact with the wheel surface of the roller, and a through hole is formed on the lubrication wheel.

[0009] Preferably, the two arc-shaped blocks are symmetrically slidably disposed in the arc-shaped cavity, one end of the spring abuts against the arc-shaped block, and the other end of the spring abuts against the inner wall of the arc-shaped cavity, and the arc-shaped blocks are made of rubber.

[0010] Preferably, the lubrication shell has symmetrically arranged oil inlets, and the two oil inlets are respectively connected to two arc-shaped cavities.

[0011] Preferably, the oil discharge mechanism consists of an oil outlet and an oil outlet chamber, the oil outlet chamber being located inside the bearing housing, and the oil outlet being located at the bottom end of the oil outlet chamber.

[0012] Preferably, both the oil inlet of the lubrication housing and the oil outlet of the bearing housing are threaded with caps.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] During use, the self-lubricating component of this utility model pneumatic assembly tool drives the self-lubricating mechanism to work as the shaft of the pneumatic assembly tool rotates, and lubricating oil enters between the shaft and the bearing body to complete the self-lubrication operation of the pneumatic assembly tool.

[0015] After use, the lubricating oil passes through the bearing body under pressure and enters the oil outlet chamber, and is finally discharged from the bearing housing through the oil outlet.

[0016] During use, the self-lubricating mechanism drives the shaft to rotate the ring, which in turn drives the roller to rotate inside the lubrication housing. The rotating roller then drives the lubrication wheel to rotate. When the through hole on the lubrication wheel connects the arc-shaped cavity and the lubrication housing, the lubricating oil in the arc-shaped cavity is thrown out through the lubrication wheel. The thrown-out lubricating oil eventually enters the bearing housing to lubricate the bearing body.

[0017] Furthermore, through the design of the arc-shaped blocks and springs, when the lubricating oil in the arc-shaped cavity decreases, the spring loses pressure and returns to its length, which drives the two arc-shaped blocks to slide closer to the lubricating wheel in the arc-shaped cavity. The remaining lubricating oil in the arc-shaped cavity is concentrated by the arc-shaped blocks to the vicinity of the lubricating wheel, thus facilitating the lubricating wheel to discharge the lubricating oil.

[0018] Personnel can periodically unscrew the cap to replenish the lubricating oil in the arc-shaped cavity through the oil inlet and discharge the used lubricating oil in the oil outlet through the oil outlet.

[0019] This utility model uses a shaft to drive a self-lubricating mechanism. During operation, lubricating oil can be actively delivered between the shaft and the bearing body to ensure that the bearing is in a good lubrication state for a long time. The lubricated oil can be recovered to the oil outlet chamber under pressure permeation and discharged through the oil outlet, which helps to prevent oil accumulation and contamination, and is also easy to replace.

[0020] By using an arc-shaped block and spring device, the remaining lubricating oil in the arc-shaped cavity can be automatically concentrated near the lubrication wheel when the oil level decreases, thereby improving the utilization rate of lubricating oil. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] like Figures 1-5 As shown, the present invention proposes a self-lubricating assembly for a pneumatic assembly tool, which includes a shaft 1, a bearing housing 2 and a lubrication housing 3. The bearing housing 2 and the shaft 1 are rotatably connected by a bearing body 8. An oil discharge mechanism is provided inside the bearing housing 2 to discharge waste oil.

[0031] The lubrication shell 3 is located on the bearing shell 2. A self-lubricating mechanism 7 is provided between the lubrication shell 3 and the bearing body 8. The self-lubricating mechanism 7 is used to perform self-lubrication on the bearing body 8. There are two sets of self-lubricating mechanisms 7, which are symmetrically distributed relative to the bearing body 8. During use, when the shaft 1 of the pneumatic assembly tool rotates, it drives the self-lubricating mechanism 7 to work, and the lubricating oil enters between the shaft 1 and the bearing body 8 to complete the self-lubrication of the pneumatic assembly tool.

[0032] Example 2

[0033] like Figures 1-5 As shown, the self-lubricating pneumatic assembly tool component proposed in this utility model, compared with Embodiment 1, further includes:

[0034] The self-lubricating mechanism 7 consists of a ring 701, a wheel frame 702, a roller 703, a through hole 704, a lubricating wheel 705, an arc-shaped cavity 706, an arc-shaped block 707, and a spring 708. The ring 701 is mounted on the shaft 1, the wheel frame 702 is mounted on the ring 701, and the roller 703 is rotatably mounted on the wheel frame 702. The arc-shaped cavities 706 are symmetrically formed within the lubrication shell 3, and the lubricating wheel 705 is rotatably mounted within the arc-shaped cavity 706. The lubricating wheel 705 partially penetrates the lubrication shell 3, and the wheel surface of the lubricating wheel 705 is parallel to the wheel surface of the roller 703. The self-lubricating mechanism 7 is in contact with each other. A through hole 704 is opened on the lubricating wheel 705. During use, the shaft 1 drives the ring 701 to rotate, and the ring 701 drives the roller 703 to rotate in the lubrication shell 3. At this time, the rotating roller 703 drives the lubricating wheel 705 to rotate. When the through hole 704 on the lubricating wheel 705 connects the arc cavity 706 and the lubrication shell 3, the lubricating oil in the arc cavity 706 is thrown out through the lubricating wheel 705. The thrown-out lubricating oil finally enters the bearing shell 2 to lubricate the bearing body 8.

[0035] Two arc-shaped blocks 707 are symmetrically slidably disposed within the arc-shaped cavity 706. One end of the spring 708 rests against the arc-shaped block 707, and the other end of the spring 708 rests against the inner wall of the arc-shaped cavity 706. The arc-shaped blocks 707 are made of rubber. Through the design of the arc-shaped blocks 707 and the spring 708, when the lubricating oil in the arc-shaped cavity 706 decreases, the spring 708 loses pressure and returns to its length, which drives the two arc-shaped blocks 707 to slide closer to the lubrication wheel 705 within the arc-shaped cavity 706. The remaining lubricating oil in the arc-shaped cavity 706 is then concentrated by the arc-shaped blocks 707 to the vicinity of the lubrication wheel 705, thereby facilitating the lubrication wheel 705's output of lubricating oil.

[0036] The oil discharge mechanism consists of an oil outlet 5 and an oil outlet chamber 9. The oil outlet chamber 9 is located inside the bearing housing 2, and the oil outlet 5 is located at the bottom of the oil outlet chamber 9. After use, the lubricating oil passes through the bearing body 8 under pressure and enters the oil outlet chamber 9, and finally exits the bearing housing 2 through the oil outlet 5.

[0037] The lubrication housing 3 is symmetrically provided with oil inlets 4. The two oil inlets 4 are respectively connected to the two arc-shaped cavities 706. The oil inlets 4 of the lubrication housing 3 and the oil outlets 5 of the bearing housing 2 are both threaded with caps 6. Personnel can periodically unscrew the caps 6 to replenish the lubricating oil in the arc-shaped cavity 706 through the oil inlet 4 and discharge the used lubricating oil in the oil outlet cavity 9 through the oil outlet 5.

[0038] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
