Technical Field

The invention relates to an assembly process of all lubricating oil to be coated, in particular to a siphon oil injection assembly method which is particularly suitable for coating lubricating oil on the surface of an inner cavity with high oil content requirement.

Background

At present, the industry mostly adopts manual or mechanical smearing of lubricating oil; the manual smearing easily causes the conditions of uneven smearing and smearing parts on certain complex surfaces, and the manual smearing cannot be accurately quantified, so that a series of adverse conditions are caused; mechanical smearing is more accurate than manual smearing in oil quantity control, but needs an accurate positioning surface or positioning point, the consistent type of parts is good, otherwise, phenomena such as collision and the like can be caused to damage the parts or an oiling nozzle, meanwhile, a repeated test is needed to obtain proper grease spraying pressure and feeding quantity, and the mechanical smearing is not suitable for smearing lubricating oil on the surface of the inner cavity of the complex part.

Disclosure of Invention

The invention provides a siphon oil injection assembly method, which is characterized in that an oil coating rod is made of a high-molecular chemical fiber material, a part is placed on the oil coating rod by utilizing a siphon principle, and the oil coating rod extends into the surface of an inner cavity of the part, so that lubricating oil can be quickly and uniformly adsorbed, and the using amount of the lubricating oil can be accurately controlled.

Therefore, the technical scheme of the invention is as follows: the siphon oil injection assembly method is realized based on a siphon oil injection assembly clamp;

the siphon oil injection assembly fixture comprises an oil storage tank, an oil coating rod made of polymer chemical fiber materials and a positioning block, wherein an oil injection port is formed in the oil storage tank; the positioning block is made of polyformaldehyde materials and is connected to the top of the oil storage tank, and a cavity with an empty part outline is formed in the positioning block; the oiling rod penetrates through the through hole of the positioning block and is arranged in the oil storage tank, a return spring of the oiling rod is arranged between the tail of the oiling rod and the inner bottom of the oil storage tank, and the head of the oiling rod is an oiling part which extends deep into the surface of the inner cavity of the part; the polymer chemical fiber material is a material with good capillary adsorption effect;

the siphon oil injection assembly method comprises the following steps: the part is placed on the siphon oil injection assembly fixture, the oil coating rod made of the high polymer chemical fiber material extends into the surface of the inner cavity of the part, and lubricating oil can be uniformly injected after the oil coating rod is placed for a specified time according to the oil coating amount.

Further explanation of the above technical solution: manufacturing an oiling rod by adopting a sodium polyacrylate cross-linked substance or a polyvinyl alcohol cross-linked polymer; the prior macromolecular chemical fiber is easy to obtain and implement.

The technical scheme is further limited as follows: the number of the oil coating rods is 1 or more, and the number of the oil coating rods is determined according to the number of parts needing oil injection of the part.

The invention has the beneficial effects that: the invention has the innovative idea that by utilizing the siphon principle and adopting the high-molecular chemical fiber with good capillary adsorption effect as the oiling rod, the parts can quickly and uniformly adsorb lubricating oil when being placed on the oiling rod, the consumption of the lubricating oil can be accurately controlled, and the quality stability is greatly improved; and the positioning block is made of polyformaldehyde materials, so that the surface of the part cannot be damaged in the process of placing the part.
