Description
Technical field
The present invention is a kind of to carry out the test method that sparking plug discharge voltage is tested under air pressure, belongs to sparking plug gas in aero-engine
Depress discharge voltage technical field of measurement and test.
Background technology
Sparking plug is the important accessory of aircraft engine, and the sparking plug of my company production at present has tens of kinds, largely will be into
The test of discharge voltage is depressed in promoting the circulation of qi.And in early period, many semiconductor devices, semi-conducting glaze part are also required to carry out under air pressure
Discharge voltage is tested, and after qualified, could be used to subsequently assemble.
The fixture of discharge voltage and equipment under sparking plug or part air pressure are tested at present to be connected as a single entity, and are telescoping structures.Survey
Need to select appropriate rubber washer to be sleeved on sparking plug one end during examination, different sparking plugs, the size of the rubber ring used and how rare
Institute is different.Tightened after sparking plug and rubber ring loading sleeve, then with dedicated nut.The advantages of structure is can not only to carry out air pressure
Lower discharge voltage test, but also the air-tightness of sparking plug can be detected.But the structure also has several drawbacks in that：1. rubber ring dress it is more and
Again clamping.When rubber ring fills more, dedicated nut can not be screwed into, it is necessary to clamping again.2. rubber ring fills clamping less and again.Rubber
When cushion rubber dress is few, after dedicated nut is screwed into, it is impossible to hold out against rubber ring, gas leakage, it is necessary to clamping again.3. rubber ring dress partially or with electricity
The bad and gas leakage of mouth fitting, it is necessary to clamping again.4. test semiconductor device or semi-conducting glaze part, because clamping
It is firmly excessive, it there may come a time when to damage semiconductor device, make part rejection.5. during sparking plug product clamping, it is possible to electricity
Nozzle surface causes to scratch or bump injury, scraps sparking plug.6. clamping causes workload to increase repeatedly, manufacturing schedule is influenced, and
Operator's mood is influenced, is caused a hidden trouble to work quality.7. need to select the clamp part of assembling more, it is necessary to carry out more during clamping
Secondary selection adjustment.
The content of the invention
The purpose of the present invention：The greatest drawback of electric discharge voltage fixture is to be unable to clamped one time success under existing air pressure,
Clamping not only causes being greatly lowered for efficiency repeatedly, influences manufacturing schedule, and production is be easy to cause in clamping process
The bump injury of product or spare part, causes product quality to lose；Clamping repeatedly, can also adversely affect operator's mood,
In turn can be to reducing test mass.
Cause repeatedly clamping factor be primarily due to sparking plug shape size it is of all kinds, indivedual sparking plug structures are very special
Not, it is not easy to clamping；The influence of the size of rubber ring；Large washer, the size of small washer internal diameter and sparking plug matching part are cylindrical big
It is small etc..The quality that test fixture coordinates with sparking plug, into the principal element for influencing clamping effect.In addition, more (the numbers of clamping parts
Ten kinds of rubber rings of different sizes, the different big small washer of dozens of internal diameter, several dedicated nuts of different sizes etc.), make dress
Complicated with process, operability is poor.Because every batch of product testing amount is very big, each product carries out discharge voltage under air pressure
During test, being wasted repeatedly caused by clamping to estimate.
The core of electric discharge voltage test case is that test fixture makes box under Novel pressure, and tested exemplar is put into
In case, it is connected with two electrodes, then covers case lid.Maximum is not both that fixture does not have to be coordinated with each product,
So being adapted to the test of all existing spare parts, testing efficiency can at least improve more than 4 times.Fig. 1 is to be tested under Novel pressure
Discharge voltage fixture.The purpose of the present invention is exactly to improve labor efficiency, improve product testing quality, reduce product quality loss
Rate, reduce labor intensity.
Technical scheme：The test method that sparking plug discharge voltage is tested under a kind of carry out air pressure, it is characterised in that
The method based under air pressure test sparking plug discharge voltage chamber and realize, the chamber include lid 1, conducting wire 3, absolutely
Edge body 5, be measured sparking plug 6, plank 8, babinet 9：The babinet 9 is the hollow box body with oral area, and lid 1 can cover babinet
9 oral area；And it can ensure the leakproofness of babinet 9；A visual windows are provided with one side of the babinet 9, in institute
State the conducting wire 3 that babinet 9 is provided through on the opposite flank with visual windows side of babinet 9；Between conducting wire 3 and babinet 9
Insulation is kept, and ensures the leakproofness of babinet 9；It is measured sparking plug 6 to be placed in babinet 9, passes through the conducting wire 3 connected on babinet 9
It is connected on external power supply；After powering on and bringing the voltage up to certain value, it is measured from the visual windows of babinet 9
The working status of sparking plug 6.
The edge of the oral area in babinet 9 is provided with rubber seal.
It is described that 9 bottom of babinet is provided with plank 8.
The visual windows are made of tempered glass 7, are sealed around tempered glass 7 coated with fluid sealant 4.
The conducting wire 3 passes through insulator 5, and is sealed with fluid sealant 4.
Advantages of the present invention：The chamber tightly supporting, of the invention with test fixture of sparking plug or spare part need not be tested
The discharge voltage of any sparking plug or spare part under pneumatic pressure can be tested, assembling is quick and easy, and operability is good, work efficiency
Height, the accuracy of experiment is high, is not in repeatedly the phenomenon of clamping.Reason is as follows：Current fixture must select suitable size
The mode that packing ring, suitable rubber ring are assembled and tightened with screw thread is sealed, and then wiring is tested；As long as new test case will
Test product is put into seal box on plank, is connected two electrodes, can be tested after closeing the lid.Due to being tested under sparking plug air pressure
Maximum gas pressure be not more than 5MPa, so the babinet 9 of chamber and 1 binding site of lid inlay a circle rubber seal 2, lid
1 uses snap with the connection of babinet 9, simple to operate, is fully able to the needs for meeting air-tightness under regulation air pressure.Newly
The method advantage of electric discharge voltage is obvious under type air pressure：Repeated clamping is avoided, is improved labor efficiency, is improved test mass, subtracts
The bump injury of few product clamping process, reduces operator's labor intensity.
