Device, which is pulled down, to be encased in the frock of test pressure, then carries out the calibration of pressure to it on forcing press.It can be seen that existing this school
Shortcoming is existing for quasi- means and frock：The step of calibration, is more, operation it is cumbersome, calibration it is less efficient；The equipment of calibration
And frock cost is higher.
Utility model content
The purpose of this utility model is to provide a kind of axial pin type pull pressure sensor calibration tool, using the calibration tool
It is not required to when can carry out the calibration of pulling force and pressure to axial pin type pull pressure sensor on a puller system, and change calibration item
The tested sensor of dismounting.
To achieve the above object, the utility model uses following scheme：Axial pin type pull pressure sensor calibration tool, it has
There are a pair of pull bars, a connecting plate and a pair of location-plates, the one end of pull bar is provided with the groove to take the shape of the letter U, the cell wall of groove both sides
On have first mounting hole, two first mounting holes are coaxial, and the other end of pull bar is provided with a through hole, and pull bar is provided with
Two groups of screwed holes for being used to install location-plate, connecting plate is in yi word pattern, and the both ends of connecting plate are respectively provided with one second mounting hole, fixed
Position plate is lamellar, and L-shaped breach is provided with location-plate, bolt hole corresponding with screwed hole is provided with location-plate.
From such scheme, axial pin type pull pressure sensor is calibrated using frock provided by the utility model
When, take two axial pin type pull pressure sensor, a pair on second mounting hole and a pull bar loaded on connecting plate one end the
In one mounting hole, in a pair of first mounting holes on the second mounting hole and another pull bar of the another loaded on the connecting plate other end,
Connecting plate is connected between two pull bars, then two location-plates are connected on a pull bar respectively, by location-plate by axial pin type
Pull pressure sensor is blocked, positioned；After completing above-mentioned installation, two pull bars are coupled with the traction end of puller system respectively, by pulling force
Machine can carry out pulling force calibration, after completing pulling force calibration, pull down location-plate, two axial pin type pull pressure sensor are rotated
180 °, then refill upper location-plate positioning, you can pressure calibration is carried out by puller system again.
The utility model is rational in infrastructure, easy to use, and it may be implemented in, and a puller system is last to complete two axial pin types
The pulling force of pull pressure sensor and pressure calibration, and then calibration efficiency is improved, calibration cost reduction.
