Description
Technical field
The present invention relates to a kind of numerically-controlled machine tools, and in particular to a method of main shaft of numerical control machine tool is maintained.
Background technology
Numerically-controlled machine tool can all use cutting fluid when manufacturing product to cool down and lubricate, to ensure the machining accuracy of product
With the service life for improving cutter.It is had higher requirements to the waterproof sealing of equipment using cutting fluid, once seals damaged, cutting fluid can be into
Enter inside equipment, corrosion mechanical part.And the damage of sealing mechanism is a kind of high frequency event, especially in main shaft and tool contact portion
The sealing divided.At present maintenance main shaft conventional method be periodic replacement seal member, due to seal member service life not
One, cause sealing element to damage main shaft and be also possible in running order, at this point, cutting fluid is possibly into main shaft inside, and generates
Hydrops situation, folded spring and broaching tool bar inside main shaft can be immersed in water environment, cause to be rusted damage, affect main shaft for a long time
Service life.
Currently, blowing structure is typically provided in machine tool chief axis, for example, Chinese invention patent application CN106271871A is disclosed
Blowing structure in a kind of machine tool chief axis, by inner hole of spindle forward end blow, the iron filings in spindle hole are removed.It is public
The exclusion that a variety of blowing structures realize iron filings in spindle hole is opened.The purpose of these structure designs is the exclusion for iron filings, because
This will stop blowing after lathe is shut down.
During machine tooling, a small amount of cutting fluid can reach main shaft seal part, when main shaft seal performance declines or fails
When, cutting fluid will enter inside main shaft.Therefore, machine tool chief axis feed liquor how is prevented, is this field problem to be solved.
Invention content
The goal of the invention of the present invention is to provide a kind of main shaft of numerical control machine tool water discharge method, is caused with solving feed liquor inside main shaft
Immersion corrosion problem.
To achieve the above object of the invention, the technical solution adopted by the present invention is：A kind of main shaft of numerical control machine tool water discharge method, packet
Include following steps：
(1) start button of NC machine is monitored, when the first setting time start button of process is not by operating personnel
When triggering, to one air blowing logical variable of controller set of control scavenger system；
(2) controller of control scavenger system opens scavenger system, and carry out timing, works as warp in air blowing logical variable set
After crossing the second setting time, scavenger system is closed；
(3) step (1) is re-executed.
It in above-mentioned technical proposal, is blown by the time interval in setting, the cutting near sealing element can be taken away
Liquid prevents cutting fluid from entering inside main shaft by the sealing element of damage after sealing element periphery is accumulated.
Preferred technical solution, first setting time are 25~30 minutes.It is highly preferred that first setting time
It is 30 minutes.
Second setting time is 5~8 minutes.It is highly preferred that second setting time is 5 minutes.
In above-mentioned technical proposal, it is equipped with air blowing solenoid valve in the scavenger system, when air blowing logical variable set, opens
Air blowing solenoid valve, starts air blowing process automatically.
Since above-mentioned technical proposal is used, the present invention has following advantages compared with prior art：
1, the present invention can be cut with Initiative Defense main shaft liquid impregnate the case where occur, to significantly improve main shaft use the longevity
Life；
2, the present invention utilizes the scavenger system for being used to exclude iron filings in the prior art to realize numerical control machine by specifically controlling
The draining of bed main shaft can be realized therefore it may only be necessary to carry out software adjustment, can be easily transformed to existing lathe；It will
The scavenger system for being originally used for chip removal is safeguarded for main shaft, creative.
Description of the drawings
Fig. 1 is the structural schematic diagram for the Kessler main shaft being directed in the embodiment of the present invention；
Fig. 2 is the flow chart of embodiment.
Wherein：1, gas hole；2, waterproof grommet；3, spring is folded；4, cutting fluid easily accumulates position.
Specific implementation mode
The invention will be further described with reference to the accompanying drawings and embodiments：
Embodiment one：It is shown in Figure 1, a kind of Kessler main shaft for numerically-controlled machine tool, wherein with waterproof grommet 2 and folding
Spring 3, is equipped with scavenger system, and scavenger system has multiple gas holes 1 positioned at main-shaft side edge, the easy regulation of cutting fluid is shown in figure
Position 4.
For above-mentioned main shaft of numerical control machine tool, a set of water discharge method is provided.By the air blowing process and the lengthening that increase main shaft
Gassing time takes away the cutting fluid near sealing element.Referring to attached drawing 2, it is as follows：
(1) the triggering logic for calling air blowing process is write in CNC, the start button of data control host is monitored, when 30
When the start button of equipment is not triggered by operating personnel in minute, CNC is patrolled to one air blowing of PLC set of control scavenger system
Collect variable；
(2) it is equipped with air blowing logic in the PLC of control scavenger system.In air blowing logical variable set（ON）When, controller opening is blown
Gas system, blows into main shaft, and air blowing continues to stop after to the cutting fluid taken away near sealing element, and the general opening time is 5 points
Clock；
(3) step (1) is re-executed.
The present invention can prevent cutting fluid from entering in main shaft by the sealing element of damage after sealing element periphery is accumulated as a result,
Portion, to extend the service life of main shaft.
