Detailed description of the invention
Below in conjunction with Figure of description, the invention will be further described, but the invention is not limited in following
Embodiment.
As it is shown in figure 1, based on pressure transducer by series products compression resilience tester, including framework, add
Press mechanism, (usually display screen is arranged on framework top for four distance measuring sensors, data display equipments；
Figure omits) and control module (omitting in figure).
As in figure 2 it is shown, described framework includes the two pieces of mainboards 1 stood in front and back and stands on a left side
Two blocks of side plates 2 of right both sides；From top to bottom alignment and horizontally disposed in the region that mainboard and side plate surround
Top board 5, intermediate plate 6 and base plate 7.The most fixed three L-type sectioned baffle 6-2 on intermediate plate, these are three years old
Individual L-type baffle plate surrounds the square test zone of an opening, is used for positioning sample.Described intermediate plate and the end
Space between plate is used for placing motor, power supply and electronic component.
Described four sensors are arranged on four angles of top board bottom surface, downwards detection sensor and test tabletting it
Between distance.
As it is shown on figure 3, described pressing mechanism is pressure transducer pressing mechanism；This pressure transducer pressuring machine
In structure, two rotating screw mandrel 8-4 vertically arrange, and are driven by motor；Axle is passed through on the top of screw mandrel
Holding 8-6 and be positioned in the lower surface of top board 5, the lower half of screw mandrel is positioned intermediate plate 6 by bearing 8-3
Lower surface, the bottom of screw mandrel down passes over intermediate plate；Motor 8-1 is arranged on the lower section of intermediate plate, electricity
Machine rotating shaft is fixed with one of them screw mandrel bottom by shaft coupling 8-2.The left and right sides of pressurization transverse slat 8 is divided
Do not fix nut sleeve 8-16 matched with screw mandrel by mounting seat 8-13 so that the rotation of screw mandrel is converted into
The vertical motion of pressurization transverse slat.Described screw lead is usually 3-10mm, preferably 5mm.
A pressure transducer 8-18 is also fixed in the bottom of pressurization transverse slat, and pressing plate 8-20 is then fixed on pressure transducer
Bottom, this pressure transducer is further through the control module described in data wire electric connection.In figure visible: pressure
Sensor fixes (binding agent bonds or screw is fixed) under pressurization transverse slat 8-12 by Upper gasket 8-17
Surface, and fix (binding agent bonds or screw is fixed) by lower gasket 8-19 and pressing plate 8-20；Pressurization horizontal stroke
When plate down moves, just turn down pressure test product by the pressing plate of pressure transducer bottom.
For keeping the synchronized movement of two screw mandrels, this tester is provided with belt wheel mechanism；In figure visible: two
Individual screw mandrel upper end fixes a belt wheel 8-5 respectively, and configures a belt 8-7, and motor makes two by this belt wheel mechanism
Individual screw mandrel keeps synchronous axial system.
Described test tabletting (omitting in figure) is placed in the test, for flattening the upper surface (examination of sample
Sample is placed on the upper surface of lower plate)；Described test tabletting is a plane lamina, and generally foil is not (if
Rust steel disc) or nonmetallic slices (such as plastic sheet).
Further, described motor (can be able to be set by the size that pressure transducer and control system control power output
Meter special-purpose software realizes)；Effectively power output be preferably 2 f, 4 f (thrust determines as required, it is recommended that
Value is 2*9.8=19.6N).
Described motor uses power to be preferably 1NM/S.
The operation principle of described driver part is:
As shown in Figure 4, during non-pressurized state, motor 8-1 and screw mandrel 8-4 is in resting state, pressurization
Transverse slat 8-12 is maintained at above test zone.
When testing: (1) is as it is shown in figure 5,2kgf power pressurized state: first electric machine rotation, by band
Wheel mechanism drives two screw mandrels to rotate, and pressurization transverse slat 8 progressively declines, by pressure transducer and pressing plate progressively
The test tabletting of sample top is pressurizeed；When pressure transducer records test tabletting pressure size it is
19.6N (2kg*9.8N/kg), can record 2kgf force data, when pressure transducer records suffered by test tabletting
Pressure size is 39.2N (4kg*9.8/kg), for 4gkf power pressurized state, can record 4kgf power pressurization shape
State.When releasing test, motor reversal, pressurization transverse slat rises.
Described distance measuring sensor (obtains sample especially by pressing plate range finding for measuring sample thickness
Thickness data), the quantity of distance measuring sensor is four and is separately positioned on four upper summits of test zone (i.e.
The corner of top board)；Described sensor is infrared distance sensor, measures scope 10cm～80cm, certainty of measurement
≤1mm；To fully take into account ultrared transmitting boundary when arranging sensor, prevent infrared ray direct irradiation
On the support columns thus disturb range finding；Pass by the distance between distance measuring sensor and intermediate plate being deducted range finding
After distance between sensor and test tabletting, then deduct the thickness testing tabletting, i.e. can get the thickness of sample
Value.
Described control module (omitting in figure) and described sensor, data display equipment, pressure transducer electricity
Connect；Described control module is used for controlling pressure time, waiting time, data process and display measurement result.
The equal buyable of described control module, pressure transducer, distance measuring sensor obtains.
The measuring method of the present invention is as follows:
1, three groups of samples (such as silk wadding quilt) of 20cm × 20cm are prepared, by one group of sample (figure omits)
Neatly stack in the test zone of framework, test tabletting is lain in sample upper surface；
2, starting the present invention, first motor 8-1 starts, and drives belt wheel mechanism motion so that two screw mandrels synchronize
Rotating, pressurization transverse slat 8 declines；The pressure recorded on test tabletting as pressure transducer 8-18 is 19.6N
(2kg*9.8N/kg), time, after waiting 30 seconds, upward retraction pressurization transverse slat, executes sample after waiting 30 seconds again
Pressure, after being repeated 3 times above-mentioned steps, distance measuring sensor starts range finding and signal is returned control module；
3, measuring complete pressurization transverse slat for 3 times to rise, after waiting 30 seconds, driven by motor pressurization transverse slat moves down formula
Sample presses, and it is 39.2N (4kg*9.8N/kg*2) that pressure transducer records test tabletting pressure experienced, waits
The transverse slat that pressurizes after 30 seconds is retracted and is made its pressing plate depart from test tabletting, and distance measuring sensor starts range finding and returned by signal
Return control module；
4, after waiting 3 minutes, distance measuring sensor starts range finding and signal is returned control module；
5, another two groups of samples are carried out the most successively the operation of above-mentioned 1,2,3,4 steps；
6, control module draws by the compression ratio of series products and response rate after processing and calculating, and passes through data
The data that display device display obtains.
