Description
Technical field
This utility model belongs to machine industry, is specifically related to a kind of constant force spring test device.
Background technology
On current wind-power electricity generation market, the test about the operating pressure of the constant force spring in brush-box is all that detection is with many
Few power brings how much deformation to spring, simply certain situation next one definite value.But constant force spring is to act on carbon brush, and carbon brush
Being attrition component, along with work uses, the length of carbon brush is constantly reducing, thus the active length of constant force spring is also with change
Changing, the difference of active length, operating pressure is different, and as operating pressure is less than normal, carbon brush is too small with contacting of slip ring, so
Conductivity a little can be caused to decline, as operating pressure is bigger than normal, carbon brush and the excess that contacts of slip ring, so can cause the carbon brush life-span to subtract
Little.So measuring method currently on the market is the most rigorous.
Summary of the invention
For solving the problems referred to above, the purpose of this utility model is to provide a kind of constant force spring test device, and constant force spring leads to
Cross axle sleeve to be fixed on mandrel, drive digital displaying push-and-pull tensiometer to pull constant force spring by swinging handle, measure constant force spring work
Making the corresponding change numerical value of pressure and active length, certainty of measurement is high, practical.
For realizing above-mentioned technical purpose, reaching above-mentioned technique effect, this utility model is achieved through the following technical solutions:
A kind of constant force spring test device, including on the left of the spiral horizontal-vertical double-purpose testboard of handle is installed, pacify respectively
It is contained in the digital displaying push-and-pull tensiometer at two ends, two bearings on described spiral horizontal-vertical double-purpose testboard, through bearing described in two and fix
Mandrel, stroke mark chi, drag hook, be arranged on the constant force spring on described mandrel by axle sleeve；Described digital displaying push-and-pull tensiometer leads to
Crossing described drag hook to be connected with described constant force spring, described stroke mark chi is fixed on institute on described spiral horizontal-vertical double-purpose testboard
State the lower end of digital displaying push-and-pull tensiometer.
Further, described spiral horizontal-vertical double-purpose testboard is provided with the first fixed plate and the second fixed plate, institute
Stating the first fixed plate to be connected with described handle, described second fixed plate is fixed on described spiral horizontal-vertical double-purpose testboard, institute
Stating digital displaying push-and-pull tensiometer to be arranged in described first fixed plate, bearing described in two is separately mounted to two in described second fixed plate
End.
Further, described axle sleeve external diameter matches with described constant force spring internal diameter, described sleeve diameter and described mandrel
Diameter matches.
The beneficial effects of the utility model are:
Constant force spring of the present utility model is fixed on mandrel by axle sleeve, drives digital displaying push-and-pull tensiometer by swinging handle
Pull constant force spring, it is to avoid the participation of frictional force, pressure phase that the pulling force now shown and spring show in real work
Deng, clearly show the corresponding change numerical value of spring works pressure and active length, thus ensure that constant force spring makes at product
Used time acts on power on carbon brush a suitable scope, and certainty of measurement is high, practical.
