Abstract
The invention relates to a self-lubricating method for a machine tool. The method comprises the following steps which are sequentially carried out: the machine tool receives a lubricating command and starts running along a lubricating path, and meanwhile, an oil-supply signal is outputted to an oil pump, and the oil pump starts working; a numerical-control system starts detecting and judging whether the pressure of the oil pump reaches a specified range after the system operates for X time since the moment starting supplying oil; if a signal indicating that the pressure is reached is detected, the detecting of the signal indicating that the pressure is reached is finished, the oil supply is continued; and if the signal indicating that the pressure is reached is not detected after the system operates for Y time, which shows that the oil supply system is in fault, the oil-supply signal is interrupted, the failure for lubricating is record, and the fault is fed back. According to the self-lubricating method for the machine tool provided by the invention, the self-lubricating method has the beneficial effect that the lubricating effect for machine tools can be remarkably enhanced.
Description
Technical field
The present invention relates to a kind of self-lubricating method for machine tool.
Background technology
In order to improve Digit Control Machine Tool service life, guarantee the Digit Control Machine Tool machining accuracy, need to reasonably maintain lathe in the Digit Control Machine Tool use procedure.This wherein one of most important method be exactly correct lubricated lathe, guarantee precision and the service life of Digit Control Machine Tool key components and parts.Particularly using when lathe is comparing under rugged environment, when using water cooling mode such as the glass-cutting lathe, if lubricating maintenance is improper, the precision parts such as machine tool guideway and leading screw are easy to get rusty and damage.Digital control system generally adopts the interval-automatic lubricating system at present, but some lathe adds man-hour at workpiece, often be fixed on motion in a zonule of machine tool travel scope, not lubricated on the stroke this zonule outside like this, be easy to cause the inefficacy of leading screw and guide rail.
Summary of the invention
The deficiency that exists in order to overcome prior art the object of the present invention is to provide a kind of lubricant effect self-lubricating method for machine tool preferably.
For reaching above purpose, the invention provides a kind of self-lubricating method for machine tool, it comprises the following steps of carrying out successively:
(1) lathe is accepted to lubricate to order and begin and is exported simultaneously fuel supply signal to oil pump along the operation of lubricated path, and oil pump is started working;
(2) digital control system is counted constantly from the beginning fuel feeding, and X begins after the time to detect and judges whether the pressure of oil pump reaches prescribed limit in operation;
(3) if the pressure arriving signal detected, finish the pressure arriving signal and detect, continue fuel feeding; If system does not still detect the pressure arriving signal after the operation Y time, represent oil supply system failure, interrupt fuel supply signal, record lubricates unsuccessfully, the feedback fault.
Further improvement of the present invention is, described self-lubricating method for machine tool moves when system boot or shutdown automatically.
Further improvement of the present invention is, comprises that lathe returns back to the step of initial point before the step 1) of described self-lubricating method for machine tool.
Further improvement of the present invention is, in the self-lubricating process, the operating path of lathe is for to move to the diagonal angle extreme position from initial point.
Further improvement of the present invention is, is also comprising the steps: after step 3) when pressure signal is normal, continues to be lubricated to distance stroke centre position D, when machine tool motion arrives apart from stroke centre position D, finishes fuel feeding for the first time; When surpassing stroke centre position D, again give fuel supply signal of grease pump at machine tool motion, begin fuel feeding for the second time, the step 3) that reruns and step 4) are until arrive the stroke end.
Further improvement of the present invention is, also comprises the steps: to return along former lubricated path after the lathe operation suspension time interval K repeating step 2) to step 3).
Further improvement of the present invention is, also comprises the step of setting self-lubricate M interval time and lubricated duration N, and the beginning continuous lubrication time is the self-lubricating of N after lathe each run time interval M.
According to self-lubricating method for machine tool of the present invention, has the beneficial effect that can significantly promote the lathe lubricant effect.
The specific embodiment
The below is described in detail preferred embodiment of the present invention, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made more explicit defining.
A kind of self-lubricating method for machine tool, it moves when system boot or shutdown automatically, and it comprises the following steps of carrying out successively:
(1) lathe is accepted to lubricate to order and begin and is exported simultaneously fuel supply signal to oil pump along the operation of lubricated path, and oil pump is started working;
(2) digital control system is counted constantly from the beginning fuel feeding, and X begins after the time to detect and judges whether the pressure of oil pump reaches prescribed limit in operation;
(3) if the pressure arriving signal detected, finish the pressure arriving signal and detect, continue fuel feeding; If system does not still detect the pressure arriving signal after the operation Y time, represent oil supply system failure, interrupt fuel supply signal, record lubricates unsuccessfully, the feedback fault.
As further improvement, comprise that lathe returns back to the step of initial point before the step 1) of self-lubricating method for machine tool.
As further improvement, in the self-lubricating process, the operating path of lathe is for to move to the diagonal angle extreme position from initial point.
As further improvement, also comprising the steps: after step 3) when pressure signal is normal, continue to be lubricated to distance stroke centre position D, when machine tool motion arrives apart from stroke centre position D, finish fuel feeding for the first time; When surpassing stroke centre position D, again give fuel supply signal of grease pump at machine tool motion, begin fuel feeding for the second time, the step 3) that reruns and step 4) are until arrive the stroke end.
As further improvement, also comprise the steps: to return along former lubricated path after the lathe operation suspension time interval K repeating step 2) to step 3).
As further improvement, also comprise the step of setting self-lubricate M interval time and lubricated duration N, the beginning continuous lubrication time is the self-lubricating of N after lathe each run time interval M.
Above embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the person skilled in the art understand content of the present invention and implemented; can not limit protection scope of the present invention with this, all equivalences that Spirit Essence is done according to the present invention change or modification all is encompassed in protection scope of the present invention.
