Air pressure lubricating oil injector and its oiling method

Abstract

The invention discloses an air pressure lubricating oil injecting device and an oil injecting method thereof. The air pressure lubricating oil injecting device comprises a fixing seat, an oil storing barrel with an opening portion, a hollow first guide pillar and a piston, wherein an air inlet-vent mouth, an oil inlet and at least one oil injecting mouth are formed in the fixing seat, the opening portion of the oil storing barrel is connected with the fixing seat in a sealed mode, a first mouth and a second mouth are respectively formed at a first end and a second end of the first guide pillar, wherein the first mouth and the second mouth are respectively communicated with inner holes of the first end and the second end of the first guide pillar, the first guide pillar is installed inside the oil storing barrel, the first end of the first guide pillar is fixed on the fixing seat, the first mouth of the first end of the first guide pillar is communicated with the air inlet-vent mouth, the piston is arranged on the first guide pillar in a sliding mode, an inner cavity of the oil storing barrel is divided into an oil cavity and an air cavity by the piston, the oil cavity is communicated with the oil inlet and the oil injecting mouth, and the air cavity is communicated with the second mouth of the second end of the first guide pillar. According to the air pressure lubricating oil injecting device, air pressure is utilized to drive the piston to inject oil, and a traditional mode that a motor is depended to drive a pump body to supply oil is replaced. The air pressure lubricating oil injecting device is simple in structure, convenient to repair and low in overall price.

Description

technical field [0001] The invention relates to a device for supplying lubricating oil into or on a machine or lubricated parts, especially an air pressure lubricating oil injector and its oiling method. Background technique [0002] The traditional lubricating oil injector relies on the motor to drive the pump body to supply oil. This kind of lubricating oil injector has a complicated structure, inconvenient maintenance, and the overall price is expensive. Some lubricating oil injectors use air pressure to inject oil, but their structures are more complicated, and there is also the problem of inconvenient maintenance. Contents of the invention [0003] The first technical problem to be solved by the present invention is to provide an air pressure lubricating oil injector with simple structure, convenient maintenance and low cost. [0004] The second technical problem to be solved by the present invention is to provide an automatic air pressure lubricating oil injection m...
