Problems solved by technology

[0003] At present, the most used solution is to use quantitative valve or quantitative pump to supply oil, but the performance of these two is not ideal in some industries. The quantitative valve cannot be adjusted according to the site conditions, and the quantitative pump is somewhat weak in micro control. And the investment cost is very high (take the quantitative valve as an example, each set of investment is about 80,000 yuan)
Especially in the assembly of the fuel pump bracket, neither of these two solutions can meet the needs very well, there is pollution on site, the fuel injection volume is greater than the demand, and it cannot be further controlled

The oil pipe, the air inlet is connected to the compressed air source through the oil supply tank pressure pipe; the tooling oil supply pipe is connected to the oil inlet channel of the oiling tool; the main oil supply pipe is provided with a main oil supply cut-off valve; the tooling oil supply pipe A precision oil control valve for tooling oil inlet is arranged on it; a pressure stop valve and a pressure reducing valve are arranged on the pressure pipe of the oil supply tank; the pressure sensor is used to detect the pressure of the air inlet of the oil supply tank. The invention also discloses an oiling tooling. The invention can supply oil to the workpiece stably, in a small amount and adjustable.

Description

technical field [0001] The invention relates to a mechanical assembly tool, in particular to a micro-oil control device and an oiling tool. Background technique [0002] In the assembly industry, some interference press-fit assemblies need to apply a certain amount of lubricating oil (grease) to the assembly parts of the parts before press-fitting to reduce the resistance during the assembly process. However, for some industries that have cleanliness requirements on site or products that have certain requirements on the amount of oil (grease) introduced, the control of oil amount is particularly important, especially in industries that use some low-viscosity oils as lubrication. To achieve a stable and continuous oil supply is an urgent problem to be solved. [0003] At present, the most used solution is to use quantitative valve or quantitative pump to supply oil, but the performance of these two is not ideal in some industries. The quantitative valve cannot be adjusted ac...
