Method realizes the application to thermometer bulb output end load.This method for applying load is fairly simple, it is only necessary to add on dial gauge
Add the counterweight of corresponding weight that can realize.But this method is then shown for requiring to apply the thermometer bulb class product compared with big load
It obtains particularly inconvenient.It needs weight and the volume of counterweight to be added all very big on dial gauge, causes entire test device very huge,
On test job carry out cause prodigious influence, be unfavorable for the installation and debugging of test device, directly affect thermometer bulb class product
Test.
Utility model content
Technical problem to be solved in the utility model is：A kind of thermometer bulb characteristic test load enlarger is provided, is utilized
Lever principle realizes the application of test load larger to thermometer bulb class product.
The technical solution of the utility model is：A kind of thermometer bulb characteristic test load enlarger, including testing jig 1, bearing
2, lever 3, dial gauge 4, counterweight 5, reference test bar 6, product shelf 7；The reference test bar 6 is mounted on testing jig 1；The dial gauge 4
It is installed on testing jig 1 by clamping device；One end of the lever 3 is fixed by bearing 2 on testing jig 1；The counterweight 5 is put
It sets on one end of lever 3, the counterweight 5 is in the same side of balance pivot with test product；The product shelf 7 passes through nut
It is locked on testing jig 1.
Further, 4 test point of the dial gauge is arranged on reference test bar 6, and one flat plate is drawn by reference test bar 6, can be straight
Connect the displacement of test reference test bar 6.
Further, 6 top of reference test bar increases steel ball structure, and it is point contact to make reference test bar 6 and lever 3.
Further, the dial gauge 4 is installed by screw thread clamp system on testing jig 1.
The utility model has the beneficial effects that：The essence of the utility model test device is lever principle, by the weight of counterweight
Power is amplified, to achieve the purpose that apply larger load.Meanwhile certain transformation is carried out by the form to lever, make to apply
The Impact direction being added on thermometer bulb class product is consistent with gravity direction, achievees the purpose that simplified test device.This device mitigates
The weight of traditional thermometer bulb class product tester, realizes the load compared with big load, facilitates the thermometer bulb class production compared with big load
The test of product alleviates the working strength of operator.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is dial gauge schematic view of the mounting position in the utility model；
Fig. 3 is the enlarged drawing of Fig. 2；
Wherein, 1- testing jigs, 2- bearings, 3- levers, 4- dial gauges, 5- counterweights, 6- reference test bars, 7- product shelfs.
Specific implementation mode
The following further describes the specific embodiments of the present invention with reference to the drawings.
Referring to Fig. 1, the utility model thermometer bulb characteristic test loads enlarger, by testing jig 1, bearing 2, lever 3, percentage
Table 4, counterweight 5, reference test bar 6,7 seven part of product shelf composition.
In use, calculating the weight for needing counterweight to be added first, in accordance with lever principle, the counterweight 5 of corresponding weight is put
It sets in counterweight installation place：Test product is mounted on product shelf 7 again, reference test bar 6 and the output end of test product is made freely to connect
It touches, then dial gauge 4 is fixed on testing jig 1, and compress certain displacement (precompressed amount).
Need the weight of counterweight to be added that can be calculated as follows：
M=FL1/L2g (1)
M --- counterweight weight (kg)；
F --- need the load (N) applied；
L1--- the distance (m) at reference test bar center to bearing centre；
L2--- the distance (m) at counterweight center to bearing centre；
G --- acceleration of gravity (N/m2)。
When test, test product experiences temperature change, and output end exports certain displacement, and push to test bar 6 moves, into
And lever motion is pushed, dial gauge tests the displacement of 6 corresponding position of reference test bar, that is, the displacement of output end output.
The utility model is suitable for requiring applying the thermometer bulb class product temperature compared with big load-displacement performance test, using thick stick
The gravity of counterweight is amplified by rod principle, to achieve the purpose that apply compared with big load.The load that can apply as needed
Size selects suitable lever to be amplified, and ensures that the weight of entire test device is unlikely to excessive, facilitates test job
Carry out.
In addition, in general, the direction of the power at lever both ends is opposite in lever construction.In the utility model
In, in order to simplify design, certain transformation is carried out to the form of lever, counterweight and test product are placed on the same of balance pivot
Side, the direction for being applied to the power on thermometer bulb class product is consistent with Weight gravity direction, reduces the transmittance process of power, improves
The purpose of thermometer bulb class product test precision.
Influence in order to avoid lever thickness to test result, by dial gauge test point be arranged on reference test bar (such as Fig. 2,
Shown in Fig. 3), one flat plate is drawn by reference test bar 6, then can directly test out the displacement of reference test bar 6, that is, thermometer bulb class product
The displacement of output end output.
It is provided with bearing arrangement in the fulcrum of lever 3, rotation friction has been maximally reduced, has avoided frictional force pair
The influence of test result.Steel ball structure is increased on 6 top of reference test bar, so that reference test bar 6 and lever 3 is realized point contact, accurately
The position that located reference test bar 6, improve the accuracy of test.
The utility model provides necessary technical support for the test of similar products, has application load big, operation side
Just the characteristics of.
