Description
Technical field
The utility model belongs to technical field of measurement and test, specially refers to a kind of power pick up calibration auxiliary mould that carries out the calibrated force sensor accuracy.
Background technology
Force sensor applications is extensive, one of requisite sensor when being test, and the only accuracy of guaranteed power sensor could guarantee the accuracy of test, so must calibrate accordingly the power sensor.As shown in Figure 1, traditional power pick up calibration is as follows with the auxiliary mould structure: by base plate (10), be fixed on support (20) on the base plate (10), the screw rod (30) that is installed on the support (20) by threaded engagement constitutes, described screw rod (30) is gone up fixedly handwheel (40).When calibration, power sensor (50) and power sensor calibration instrument (60) are positioned on the base plate (10), and over against screw rod (30), rotate handwheel (40) then, screw rod (30) is moved down under the effect of support screw thread, thereby power sensor calibration instrument (60) and power sensor (50) are exerted pressure.There is following problems in above-mentioned power pick up calibration with auxiliary mould: 1, screw rod can produce vertical force and level friction component when rotated, therefore rocks easily, and is relatively poor to neutrality, and the pressure that causes imposing on the power sensor produces radial component, influences calibration result; 2, pressure calibration can only be finished, the pulling force calibration can not be carried out.
Summary of the invention
The purpose of this utility model is to propose a kind ofly to carry out pressure and pulling force calibration and to calibrate the auxiliary mould of power pick up calibration accurately.
Power pick up calibration of the present utility model comprises base plate with auxiliary mould, vertical fixing has two columns on the described base plate, the top of described column is fixedly connected by a back up pad, key is to be provided with between described base plate and the back up pad pressing plate, and the two ends of described pressing plate are movably installed on described two columns by sleeve pipe; The central authorities of described back up pad are provided with threaded hole, and by threaded engagement an afterburning post are installed, and the bottom of described afterburning post and described pressing plate flexibly connect; Fixedly there is handwheel on the top of described afterburning post.
When test, at first power sensor and power sensor calibration instrument are positioned on the base plate, and over against afterburning post, rotate handwheel then, afterburning post is moved down under the effect of back up pad screw thread, move down thereby drive pressing plate, power sensor calibration instrument and power sensor are exerted pressure.Because the two ends of pressing plate rely on sleeve pipe and column to carry out spacing guiding, therefore can not rotate, there is not horizontal radial component in the pressure that imposes on power sensor calibration instrument and power sensor so, can guarantee that calibration result is accurate.
Further, for carrying out the pulling force calibration, the bottom of described base plate is equipped with shaft coupling.When carrying out the pulling force calibration, utilize shaft coupling that pressing plate is connected with power sensor calibration instrument and get final product.
Further, the bottom of described afterburning post is spherical, and described pressing plate is provided with spherical cavity, and the bottom of described afterburning post stretches in the spherical cavity.Can reduce the horizontal rotating force that imposes on pressing plate when afterburning post rotates like this.
Further, the central authorities of described base plate are equipped with one from bottom to top and are used for the fixedly bolt of testing force sensor, only need this bolt is screwed in the bolt hole of testing force sensor outer housing bottom, can realize treating the fixing of force cell, operation is very easy, and fixing firm.
Power pick up calibration of the present utility model is simple in structure with auxiliary mould, pressure and pulling force calibration that can the realizable force sensor, and produce radial component when having avoided traditional frock to load and cause calibrating inaccurate problem, have good practicability.
