Embodiment Construction

[0096] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0097] The precision lubrication pump includes: a pump body unit 100 , an oil volume adjustment unit 700 , a piston unit 200 , a one-way valve unit 300 , a compressed air flow adjustment unit 400 , and a liquid-gas concentric pipe unit 600 .

[0098] The pump body unit 100 has a pump body 105 , the pump body 105 has an inner chamber 106 and an oil inlet hole 102 , and the inner chamber 106 communicates with the oil inlet hole 102 . The pump body 105 also has an air volume regulating hole 107 communicating with the inner chamber 106 close to the one-way valve unit 300 .

[0099] The pump body unit 100 also includes a fixed plate 103 installed on the upper end of the pump body 105. The fixed plate 103 is fixed on the pump body 105 with a fixture. The fixed plate 103 has a hole matching the oil inlet of the pump body 105.

[0100] The fixing part...

Abstract

The invention provides a precise lubrication pump. Lubricating agents enter a liquid cavity from an oil inlet hole; compressed air is used for driving, when the compressed air enters an air cavity, the pressure at the tail part of a piston rod is increased, when the pressure is greater than the elastic force of a piston spring arranged at the front end of the piston, the piston rod forwards moves, the liquid cavity is reduced, the pressure is increased, when the pressure is greater than the elastic force of a one-way valve spring, a one-way valve plug is opened, and the lubricating agents are pumped out; the pressure of the liquid cavity is released, when the pressure is smaller than that of the one-way valve spring, the one-way valve spring is reset, and an oil outlet is sealed; when pressure of the air cavity is released, and when the pressure of the tail part of the piston rod is smaller than the elastic force of the piston spring, the piston rod is reset. The precise lubrication pump has the advantages that the miniature precise pneumatic pump capable of realizing precise oil supply is provided, the design is precise, and the precise lubrication pump is applicable to lubricating devices using various lubricating agents in metal processing.

Description

technical field [0001] The invention belongs to the technical field of lubricating pumps, in particular to a precision lubricating pump for a micro-quantity lubricating system. Background technique [0002] In the field of traditional machining, metal processing usually involves cutting, grinding, drilling, tapping, cold extrusion, bending and other processing processes that easily cause the workpiece to heat up sharply. This type of processing requires frictional contact between the workpieces. Usually, it should be Carry out timely lubrication treatment. [0003] At present, the existing metal processing lubrication and cooling mostly use lubricants such as coolants, emulsions or cutting oils. These types of lubricants are sprayed on the processing parts in large quantities during metal processing, usually in the form of uninterrupted showering. , In this way, the same cooling and lubrication are carried out in other parts that do not need cooling and lubrication, resulti...
