Description

Technical Field

[0001] This utility model relates to an air intake self-lubricating device for a pneumatic actuator. Background Technology

[0002] Chinese invention application CN114475555A discloses an automotive air dryer with a lubricant dispenser. A lubricant dispenser is installed inside a molecular sieve. When air passes through the lubricant dispenser, a certain amount of lubricating oil is carried out and stored in an air storage tank. When other air-consuming components need air, the dry air entering the component carries the lubricating oil, which not only supplies air to the component but also provides maintenance and lubrication due to the presence of lubricating oil, thus extending the component's service life. However, the lubricant dispenser is located inside the molecular sieve, making maintenance inconvenient. Utility Model Content

[0003] In view of the technical problems existing in the background art, the present invention aims to provide an air intake self-lubricating device for pneumatic actuators, which connects an air source and a pneumatic actuator respectively, and replenishes the lubricating material by replacing the lubricating material storage tank.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: the air intake self-lubricating device for a pneumatic actuator includes a main body and a lubricant storage container. The main body is provided with a first interface for connecting an air source, a second interface for connecting a pneumatic actuator, and an air passage chamber. The air passage chamber connects the first interface and the second interface. The lubricant storage container is detachably connected to the main body. The lubricant storage container is provided with a storage chamber. An overflow hole is connected between the storage chamber and the air passage chamber.

[0005] In this scheme, when the pneumatic actuator exhausts air to the air source, the air passage chamber will be depressurized, and a pressure difference will be generated between the storage chamber and the air passage chamber. The lubricating material enters the air passage chamber from the storage chamber through the overflow hole. When the air source supplies air to the pneumatic actuator, the airflow will carry the lubricating material into the pneumatic actuator to maintain and lubricate it, extend its service life, and disassemble and replace the lubricating material storage tank to replenish the lubricating material.

[0006] Preferably, the first interface and the second interface are arranged opposite to each other, and the air passage narrows at the overflow hole.

[0007] In this design, the airflow speed increases as it passes through the overflow hole, scraping away the lubricating material.

[0008] Preferably, the overflow hole is disposed on the lubricant reservoir, and the lubricant reservoir extends into the air passage chamber.

[0009] In this design, the lubricant reservoir extends into the air vent, narrowing the air vent and eliminating the need for additional machining of the main body.

[0010] Preferably, the lubricant reservoir is threadedly connected to the main body.

[0011] In this scheme, rotating the lubricant reservoir can adjust the extent to which the lubricant reservoir extends into the air passage chamber and control the degree of narrowing of the air passage chamber. By changing the degree of airflow acceleration, the amount of lubricant carried by the airflow can be adjusted to adapt to the maintenance and lubrication of various specifications of pneumatic actuators.

[0012] The beneficial effects of this invention are as follows: when the pneumatic actuator exhausts air to the air source, the air passage chamber releases pressure, creating a pressure difference between the storage chamber and the air passage chamber. Lubricating material flows from the storage chamber into the air passage chamber through the overflow hole. When the air source supplies air to the pneumatic actuator, the airflow carries the lubricating material into the actuator, providing maintenance and lubrication, extending its service life. The lubricating material storage tank can be disassembled and replaced to replenish the lubricating material. Therefore, this invention has substantial features and advancements compared to existing technologies. Attached Figure Description

[0020] See appendix Figure 1-2 This embodiment provides an air intake self-lubricating device for a pneumatic actuator, comprising a main body 1 and a lubricant storage tank 5. The main body 1 has a first interface 2 for connecting to an air source, a second interface 3 for connecting to a pneumatic actuator, and an air passage chamber 4. The air passage chamber 4 connects the first interface and the second interface. The first interface 2 and the second interface 3 are arranged opposite to each other. The air passage chamber 4 narrows at an overflow hole 7. The lubricant storage tank 5 is detachably connected to the main body 1. The lubricant storage tank 5 has a storage chamber 6. An overflow hole 7 is connected between the storage chamber 6 and the air passage chamber 4. The overflow hole 7 is located on the lubricant storage tank 5. The lubricant storage tank 5 extends into the air passage chamber 4. The lubricant storage tank 5 is threadedly connected to the main body 1.

[0021] In this embodiment, during installation, the first interface 2 is connected to the air source, and the second interface 3 is connected to the pneumatic actuator. The specific connection method is a threaded connection, but it is not limited to this. The lubricant reservoir 5 is screwed into place. When the air source supplies air to the pneumatic actuator, the air passage chamber 4 is pressurized. The airflow scrapes away the lubricant and carries it to the pneumatic actuator to maintain and lubricate it. When the pneumatic actuator exhausts air to the air source, the air passage chamber 4 is depressurized, and a pressure difference is generated inside and outside the overflow hole 7. The lubricant enters the air passage chamber 4 from the storage chamber 6 through the overflow hole 7 to replenish the lubricant in the air passage chamber 4. The lubricant is deposited in the air passage chamber 4. The threaded connection depth of the lubricant reservoir 5 can be adjusted to change the airflow speed to control the feed amount of the lubricant. The lubricant reservoir 5 needs to be provided with additional threads. The lubricant can be lubricating oil or grease, which are mature technologies.

[0022] In other alternative embodiments, the main body 1 and the lubricant reservoir 5 can also be connected by fasteners.
