Automatic oiling machine

Abstract

The invention relates to an automatic oiling machine, and belongs to the technical field of vibration absorbers of locomotive vehicles. The automatic oiling machine comprises a positioning tool for fixing a speed reducer, wherein an oil tank and three-dimensional oiling arms driven by corresponding servo motors respectively are arranged on an oil tank frame above the positioning tool, and an end oil filler pipe is arranged on each three-dimensional oiling arm; and an oil outlet of the oil tank is connected to the oil filler pipe through a three-way solenoid valve. Compared with the prior art, the automatic oiling machine has the advantages that: instructions can be inputted through a human-computer interface, the three-dimensional oiling arms coordinatively move and oil-supply systems are mutually matched, so that the oiling machine can be positioned accurately according to requirements, and hydraulic oil is accurately injected into the vibration absorbers with different specifications to avoid a series of troubles of modifying programs, replacing a positioning base, adjusting the oiling position and the like so as to truly realize automation control, save manpower resources, improve work efficiency and ensure oiling quality.

Description

technical field [0001] The invention relates to an automatic oiling machine, in particular to an oiling device for shock absorber production and maintenance, and belongs to the technical field of rolling stock shock absorber production. Background technique [0002] The rolling stock hydraulic shock absorber is an important part of the rolling stock, and its performance directly affects the running state of the rolling stock on the line. As far as the applicant knows, the oiling devices currently used by most manufacturers and repairers of shock absorbers for rolling stock are manually operated oiling machines. This affects the production efficiency of the factory and the quality of the shock absorbers, and poses a greater risk to the safe operation of rolling stock. [0003] The search found that the Chinese patents with application numbers 200920089836.8 and 200920082831.2 disclosed oil injection devices respectively, but they were not suitable for shock absorbers of roll...

AI Technical Summary

Problems solved by technology

Although this oil filling machine can automatically fill oil after judging that the shock absorber is installed in place, it still has the following main disadvantages: 1) the oil filling position is fixed, and it cannot be flexibly positioned according to needs, and cannot adapt to different specifications of shock absorbers; The measure of oil leakage prevention is to install an oil circuit switch controller on the oil outlet pipe, which has a complex structure and is inconvenient to maintain

In addition, 3) relying on the oil volume adjustment block between the oil cylinders to regulate the oil volume, the accuracy is not high enough; 4) completely relying on the detection and judgment of the machine itself, there is a possibility of injury caused by the misoperation of the oil injection machine
