Oil tank liquid level maintaining device for numerical control machine tool

Abstract

The invention provides an oil tank liquid level maintaining device for a numerical control machine tool, relates to the technical field of liquid level maintaining, and solves the problems that the liquid level of an oil tank in an existing numerical control machine tool is often monitored and maintained by a sensor, but the precision of the sensor is affected by oil dirt sometimes, so that detection failure is caused, and in addition, the oil liquid maintaining form is single, supply after treatment cannot be carried out on flown-back engine oil liquid, and normal operation of a machine can be affected due to the existence of impurities. The device comprises a sealing mechanism, and the sealing mechanism is connected to the top end of the bearing mechanism in a clamped mode. When a floating tank floats upwards, a flow control ball is driven by a stand column to synchronously float upwards, then when oil in the tank body reaches a limit value, a liquid inlet pipe is blocked through the flow control ball to maintain the liquid level, and a liquid supply maintaining mechanism is further installed on the right side of the top end face of a cover plate, a liquid supply pipe and a temporary storage box jointly form a siphon mechanism to maintain the liquid level of supplied liquid.

Description

technical field [0001] The invention belongs to the technical field of liquid level maintenance, and more specifically relates to an oil tank liquid level maintenance device for a numerically controlled machine tool. Background technique [0002] The CNC machine tool automatically processes the processed parts according to the pre-programmed processing program. We write the processing route, process parameters, tool trajectory, displacement, cutting parameters and auxiliary functions of the parts into a processing program sheet according to the instruction code and program format specified by the CNC machine tool, and then record the contents of the program sheet On the control medium, it is then input into the CNC device of the CNC machine tool to direct the machine tool to process the parts, and the oil tank in the CNC machine tool needs to use sensors to maintain the liquid level inside the oil tank when supplying oil, but this method There are major flaws. [0003] For...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides an oil tank liquid level maintenance device for CNC machine tools to solve the problem that sensors are often used to monitor and maintain the oil tank liquid level in existing CNC machine tools, but the sensors are sometimes contaminated by oil. The accuracy will be affected, which will lead to the failure of the detection. Moreover, the form of oil retention is single, and the returned oil cannot be supplied after treatment. The normal operation of the machine will be affected by the presence of impurities.
