Description
Technical field
The invention belongs to Grinding Technology fields, especially with a kind of idle running that disappears, anti-collision in Grinding Process
It is related to hit method.
Background technique
With the continuous development of modern processing, there is higher requirement to processing efficiency, quality, safety.It is grinding
Cut in processing, be effectively ground according to general grinding technique have casting skin-slightly into-progress greatly-light is into the equal stage successively processed, Mei Gejie
The technological parameter of section is different, will reduce the grinding idle running time as far as possible to improve processing efficiency, i.e., carry out before effective grinding
F.F. and become fastly, F.F. is the feeding of quick idle stroke, is become fastly quickly to tend to close to workpiece, easy in F.F. and become fastly during
It collides, so that anticollision is the most important thing of grinding safety.The idle running that disappears is required to quickly and accurately identify grinding wheel and work
The initial contact of part, anticollision are required to quickly identify the collision time of grinding wheel and workpiece.Existing idle running and the anticollision skill of disappearing
Art is the contact condition that grinding wheel and workpiece are judged by acquisition vibration signal or voice signal, due to vibration signal and voice signal
Vulnerable to interference, causes control inaccurate, collision is be easy to cause to damage.
Summary of the invention
The purpose of the present invention is intended to provide a kind of for the idle running that disappears in Grinding Process, collision-proof method.
For this purpose, idle running, collision-proof method the invention adopts the following technical scheme: a kind of grinding disappears, characterized in that institute
The idle running that disappears stated, collision-proof method will effectively grinding be divided into casting skin-slightly into-progress greatly-light into the-light delay grinding stage, effective
F.F. is used in idle stroke feeding before grinding and becomes to carrying out the idle running that disappears fastly, passes through the real-time current for acquiring grinding wheel spindle driving motor
Signal judges the contact condition of grinding wheel and workpiece；The fast input for forming idle stroke is set according to parts to be processed and the amount that becomes fastly, and
Default fast forward speed and the speed that becomes fastly, are arranged the functional test that becomes fastly before the first part grinding of same model specification by the gross,
Test sets the electricity of grinding wheel spindle driving motor when becoming functional test F.F. fastly by testing button starting in the controls is arranged
Flow valuve is no-load current, sets the current value of grinding wheel spindle driving motor at the end of becoming fastly as target current, target current is zero load
3 times of electric current, retreat Aligning control at the end of becoming fastly, watch whether piece surface encounters grinding wheel, if part has encountered grinding wheel
The fast input and the amount that becomes fastly of setting meet the requirements, the fast input of standard processed as subsequent parts and the amount that becomes fastly, if in F.F.
The real-time current of grinding wheel spindle driving motor reaches target current and then feed-disabling and retracts origin during becoming fastly, adjusts F.F.
Amount and the amount that becomes fastly are become functional test fastly again, until the amount that becomes until fast input and fastly meets the requirements；Become functional test completion fastly
Enter batch grinding afterwards, in grinding process, the real-time current value of grinding wheel spindle driving motor is greater than no-load current when F.F.,
It feed-disabling and retracts automatically immediately, the real-time current value for grinding wheel spindle driving motor of following the fashion fastly is greater than target current, automatically switches
The stage is effectively ground to casting skin.
Using the present invention can achieve it is following the utility model has the advantages that by the idle stroke before effective grinding in grinding into
Become to carrying out the idle running that disappears using F.F. and fastly to middle, and by the real-time current signal of acquisition grinding wheel spindle driving motor judge grinding wheel and
The functional test that becomes fastly is arranged before first part grinding and adjusts fast input and the amount that becomes fastly, realizes for the contact condition of workpiece
Anticollision improves grinding efficiency and machine safety.
Specific embodiment
The method of the present invention are as follows: will effectively grinding be divided into casting skin-slightly into-progress greatly-light into the-light delay grinding stage, effective
F.F. is used in idle stroke feeding before grinding and becomes to carrying out the idle running that disappears fastly, passes through the real-time current for acquiring grinding wheel spindle driving motor
Signal judges the contact condition of grinding wheel and workpiece；The fast input for forming idle stroke is set according to parts to be processed and the amount that becomes fastly, and
Default fast forward speed and the speed that becomes fastly, are arranged the functional test that becomes fastly before the first part grinding of same model specification by the gross,
Test sets the electricity of grinding wheel spindle driving motor when becoming functional test F.F. fastly by testing button starting in the controls is arranged
Flow valuve is no-load current, sets the current value of grinding wheel spindle driving motor at the end of becoming fastly as target current, target current is zero load
3 times of electric current, retreat Aligning control at the end of becoming fastly, watch whether piece surface encounters grinding wheel, if part has encountered grinding wheel
The fast input and the amount that becomes fastly of setting meet the requirements, the fast input of standard processed as subsequent parts and the amount that becomes fastly, if in F.F.
The real-time current of grinding wheel spindle driving motor reaches target current and then feed-disabling and retracts origin during becoming fastly, adjusts F.F.
Amount and the amount that becomes fastly are become functional test fastly again, until the amount that becomes until fast input and fastly meets the requirements；Become functional test completion fastly
Enter batch grinding afterwards, in grinding process, the real-time current value of grinding wheel spindle driving motor is greater than no-load current when F.F.,
It feed-disabling and retracts automatically immediately, the real-time current value for grinding wheel spindle driving motor of following the fashion fastly is greater than target current, automatically switches
The stage is effectively ground to casting skin.
