Description
Technical field
The present invention relates to a kind of product Crack Detection field, in particular disclose a kind of air tightness detection system and fill with workpiece
Folder abnormity early warning method.
Background technology
In processing workpiece fabrication, a lot of scrap (as aluminum is considered to be worth doing) can be produced, and scrap appears in any position, existing clamping
All manually fixture to be blown clean before product, but manual operation exist a uncertain factor: it cannot be guaranteed that in fixture with work
The face that part is close to can blow clean every time, therefore arise that processing a large amount of workpiece time, unavoidable occasional occur in fixture with work
The face that part is close to because do not blow clean, causes one or two size to happen occasionally, because because of clamping beyond the situation of mismachining tolerance
Cause workpiece to exceed the ratio of total processing quantity shared by the workpiece of mismachining tolerance the least, be therefore difficult to be inspected by random samples out, but such as
Really these substandard products arise that very big adverse effect in flowing into client's hands.
Summary of the invention
Because the drawbacks described above of prior art, the technical problem to be solved is accurately to judge fixture and workpiece
The face being close to the most really blows clean, and when the ground drying that fixture and workpiece are not close to by operator is clean, board can not start,
Must again blow clean and could start.
The concrete technical scheme of the present invention is as follows:
A kind of air tightness detection system, it is characterised in that include air inlet, trachea, gas pressure detector, air pressure change signal
Output lead, CNC board, gas-tpe fitting, fixture, fixture and work piece interface, passage and workpiece to be processed；Described passage is straight
Footpath is between 0.4mm-2.0mm.
Preferably, described passage at least one.
Preferably, described tracheal diameter is between 4mm-8mm, and described trachea connects with gas pressure detector, and described air pressure is examined
Survey device to be electrically connected with CNC board by air pressure change output line.
Preferably, the other end of described gas pressure detector connects with described fixture, and at gas pressure detector and described fixture
Between be provided with a gas-tpe fitting.
Preferably, described gas-tpe fitting connects with the passage of described fixture.
Preferably, described workpiece is close to fixture and work piece interface.
Preferably, described passage diameter is at 0.4mm, or 0.8mm, or 1.0mm, or 1.5mm, or 1.8mm, or 2.0mm.
Preferably, described number of air hole is more than 1, or 2, or 3, or 3.
Preferably, described tracheal diameter is 4mm, or 6mm, or 8mm.
The invention still further relates to a kind of workpiece clamping abnormity early warning method, it specifically comprises the following steps that
(1) scrap in the plane of fixture location, is cleaned；
(2), workpiece is put in the plane of fixture location；
(3), open air valve, gas is injected from air inlet；
(4) if having scrap in the plane of fixture location, then on gas pressure detector, data will diminish, and be believed by air pressure change
Voltage signal is input to CNC board by number output lead, and CNC board will quit work；
(5) if without scrap in the plane of fixture location, then on gas pressure detector, data, by little for change, are become by air pressure
The voltage signal changing output line output is input to CNC board, and makes air pressure and judge normally, and CNC board will continue work
Make.
Operation principle: increase some passages in the critical surfaces of fixture, and it is coupled together with air pressure detection table, gas
The air pressure signal of pressure detector couples together with the enabling signal of CNC board, and air inlet accesses the gas of air pressure constant, by gas
In hole, whether the size variation of air pressure exceedes the steady state value set by gas pressure detector and judges at the bottom of the fixture being close to workpiece
Whether face blows clean.When the fixture bottom surface being close to workpiece does not blows clean, can there is gap with fixture location plane in workpiece,
Now the air pressure in pore can reduce, and when the steady state value that air pressure not up to sets, air pressure detection table has signal and feeds back to machine
Platform, thus board can not start.
The present invention has such advantages as relative to prior art and effect:
By setting up one by air inlet, trachea, gas pressure detector, air pressure change output line, CNC board, trachea
Joint, fixture, fixture and work piece interface, passage and the cavity of workpiece to be processed composition, utilize gas pressure detector to detect
The air-tightness of cavity, is converted to electronic signal by a kind of objective fact whether the fixture bottom surface being close to workpiece blows clean, logical
Cross air pressure change output line and gas pressure detector is obtained treated electronic signal transmission in CNC board, control
Whether the startup of CNC board, thus avoids the generation of the substandard products caused because of human operational error.

Fig. 3 is fixture sectional view.
Being labeled as in accompanying drawing: 1-air inlet, 2-CNC board, 3-air pressure change output line, 4-passage, 5-presss from both sides

Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in further detail, but embodiments of the present invention are not limited to this.
Fig. 1 is air tightness detection system overall diagram, and Fig. 2 is fixture top view, and Fig. 3 is fixture sectional view.
Air tightness detection system, including air inlet 1, CNC board 2, air pressure change output line 3, passage 4, fixture
With work piece interface 5, workpiece to be processed 6, fixture 7, gas-tpe fitting 8, trachea 9, gas pressure detector 10.
Before workpiece to be processed loads fixture, blow clean the aluminium scrap bits of fixture and work piece interface, when workpiece to be processed 6
After loading fixture 7, the gas of input tape certain pressure from air inlet 1, gas passes through gas pressure detector 10 through trachea 9, and
And enter into the air cavity that workpiece to be processed 6 is formed with trachea 9, passage 4, additionally the data of gas pressure detector 10 detection pass through gas
Buckling output line 3 is transferred to CNC board 2.If fixture is considered to be worth doing with the aluminium scrap on work piece interface 5 and is blown clean, then gas
Air pressure in chamber is the most stable, then the atmospheric pressure value that gas pressure detector 10 detects is a steady state value, and fixture and absorption surface are described
Aluminium scrap bits on face 5 are dried clean, and workpiece to be processed clamping is normal, and CNC board 2 normally starts.If fixture and absorption surface
Also have aluminium scrap bits not to be dried on face 5 clean, i.e. gas can leak out with work piece interface 5 from fixture, then the gas in air cavity
Pressure can change, and the atmospheric pressure value that i.e. gas pressure detector 10 detects is a changing value, illustrates that workpiece to be processed clamping is abnormal, CNC machine
Platform 2 can not normally start, it should cleaning fixture and the aluminium scrap bits on work piece interface 5 again, again detects, until clamping is normal
Till.
Above-described embodiment is the present invention preferably embodiment, but embodiments of the present invention are not by above-described embodiment
Limit, the change made under other any spirit without departing from the present invention and principle, modify, substitute, combine, simplify,
All should be the substitute mode of equivalence, within being included in protection scope of the present invention.
