Method.
To achieve the above object, the present invention adopts the following technical scheme:
A kind of control method for preventing main shaft bearing from burning, before the main shaft bearing of lathe carries out high rotary speed working
When, by PLC control program, force control spindle shaft to make the warming-up work of step condition operating, wherein PLC control program
Control mode includes:
When the revolving speed of main shaft bearing operating is less than specified order revolving speed, downtime meets or is unsatisfactory for, PLC control
Program is all not involved in control, and the main shaft bearing of lathe works normally；
When the revolving speed of main shaft bearing operating is equal to specified order revolving speed, downtime meets or is unsatisfactory for, PLC control
Program, which is not involved in, to be controlled, and the main shaft bearing of lathe can run well；
When the revolving speed of main shaft bearing operating is greater than specified order revolving speed, downtime is unsatisfactory for, and PLC control program is not situated between
Enter to be controlled, the main shaft bearing of lathe can run well
When the revolving speed of main shaft bearing operating is greater than specified order revolving speed, and downtime meets, PLC control program intervention
It is controlled, the main shaft bearing pressure for controlling lathe stops working, and then makes main shaft bearing by PLC control program again
The warming-up work of step condition operating is done, after completing warming-up work, the main shaft bearing of lathe can run well.
Further, a kind of control method for preventing main shaft bearing from burning, wherein the step condition fortune
The warming-up work turned reaches the process of specified order revolving speed to start running from the slow-speed of revolution.
Further, a kind of control method for preventing main shaft bearing from burning, wherein the specified order
Revolving speed of the speed of revolving speed between 1/3 to 1/2 high revolving speed.
Further, a kind of control method for preventing main shaft bearing from burning, wherein transported in step condition
When the warming-up work turned, PLC control program forcibly closes the operation for resetting, shutting down.
According to the above aspect of the present invention, the present invention has at least the following advantages:
The present invention is controlled by PLC control program, under the premise of not needing other hardware, is carried out additionally to lathe
Control, makes it ensure the integrity of main shaft bearing, reduces the replacement efficiency of the main shaft bearing of lathe, improve the performance of lathe, right
The maintenance cost in later period opposite can also be reduced.
The above description is only an overview of the technical scheme of the present invention, in order to better understand the technical means of the present invention,
And can be implemented in accordance with the contents of the specification, the following is a detailed description of the preferred embodiments of the present invention and the accompanying drawings.
