Description
Technical field
The present invention relates to belt tension meter calibrating devices.
Background technology
Belt tension meter is used to measure the tension of belt.During belt tension meter calibrating, usually belt one end is fixed, separately
One end loads certain pulling force by belt tension, and the both ends of belt are fixed, and belt tension meter then is stuck in tensioning
On belt, numerical value and the size of pulling force that comparative belt tensometer measures, so as to be calibrated to belt tension meter.But it uses
When this calibration method is calibrated, since belt both ends are fixed, when belt tension meter is stuck on belt, belt is by tensometer
Clamping force and crimp occurs in contact point, so allow for belt tension that tensometer measures some for belt from
There are large errors between elastic force caused by body flexible deformation, with belt actual tension, it is impossible to effectively to tensometer into
Row calibration.
The content of the invention
It is an object of the invention to provide a kind of accurate belt tension meter calibrating devices of calibration result.
In order to solve the above-mentioned technical problem, belt tension meter calibrating device of the invention adopts the following technical scheme that：Belt
Tensiometer calibrating device, including pedestal and belt, the first end of belt is connected to by buffer spring on pedestal, is also set on pedestal
It is useful for pulling the second end of belt so that belt tension or the strainer loosened, the second end of belt pass through pulling force sensor
It is sequentially connected with the mobile output terminal of the strainer.The first end of belt is connected by buffer spring with pedestal, then
When tensometer is stuck on belt and so that the belt is subject to the lateral pressure of tensometer, the first end of belt can be in the elasticity of buffer spring
Certain displacement occurs under cushioning effect, this partial dislocation eliminates the crimp of belt itself generation, this is just further carried
The order of accuarcy for the belt tension that high tensometer detects, and then improve the calibration accuracy of belt tension meter.
Further, the pedestal is equipped with the reverse wheel for bypassing for belt and bending belt.Skin is made by reverse wheel
Band commutation bending, reduces the length or height needed for device tightening belt.
Further, belt bypasses the L-shaped arrangement of reverse wheel, then and the strainer on device vertically or horizontally arranges,
So that the stability of whole device is preferable.
Further, the strainer is leadscrew-nut mechanism, the leading screw of the leadscrew-nut mechanism vertically extension and

Plate, pressure strip and lock pin, the first end of belt form up and down that overlay segment, the upper and lower overlay segment are compacted after turning back around lock pin
It is fixed between connecting plate and pressure strip.It is easy to connect by the way of being fixed, and since the first end of belt is around lock
Pin turns back and forms overlay segment up and down, and when connecting plate and pressure strip compress upper and lower overlay segment, lock pin can avoid belt
First end is deviate between connecting plate and pressure strip so that the connection of belt and the first connector is relatively reliable.
Further, adjustable adjusting block, buffer spring are installed along the extending direction of the first end of belt on the pedestal
One end be connected with the first connector, the other end is connected with adjusting block.The initial bit of buffer spring can be adjusted by adjusting block
It puts, can easily adjust the pretightning force of buffer spring.
Further, adjusting screw rod is equipped with along the extending direction of belt first end on pedestal, adjusting block is sleeved on adjusting spiral shell
On bar, the homonymy Screw assembly on adjusting screw rod in the connection buffer spring of adjusting block is useful for limiting the adjusting of adjusting block position
Nut.The pretightning force of buffer spring is adjusted by adjusting nut, easy to adjust, accuracy is high.
Further, the buffer spring there are two and be connected on adjusting block, two buffer springs, which are located at, to be adjusted
The both sides of screw rod, two buffer springs are connected by c-type linking arm with the first connector, and the both ends of c-type linking arm connect respectively
Two buffer springs, the recess portion of c-type linking arm and the first connector, which hook, to be connected.Two buffer springs are connected to c-type linking arm
Both ends, the recess portion of c-type linking arm and the first connector, which hook, to be connected, so if the first connector and/or c-type linking arm are sent out
Raw relative swing, the first connector can be slided along the recess portion of c-type linking arm, can ensure the extension of two buffer springs
Axis and the first connector, that is, belt are parallel always, and buffer spring power transmission is stablized.
