Description

In the general calibrating installation of light-duty reisilometer

Technical field

The utility model relates to a kind of in the general calibrating installation of light-duty reisilometer.

Background technology

The flange guide rail form of original reisilometer calibrating installation makes will be to the different reisilometer calibrating installation of the reisilometer of different model configuration, and pointer cover plate position, size and flange guide rail position in these calibrating installations, size are not general to the calibrating of different model reisilometer yet.For a kind of reisilometer calibrating installation can be examined and determine the reisilometer of plurality of specifications, Chinese invention patent application " reisilometer calibrating installation and using method thereof (publication number CN102818738) " has proposed a kind of unitized reisilometer calibrating installation and corresponding using method.The general calibrating installation of reisilometer that provides of this invention wherein, be " to be formed by base and tressel; be connected with the tressel guide rail mechanism between tressel and the base; on the side vertical with the tressel guide rail riveting stake is installed on the base; annular power sensor, displacement transducer are arranged; a pair of flange guide rail and support, resiliometer casing locating device and the pointer cover plate that cooperate with reisilometer movement upper flange in addition on the tressel; pointer, pointer guide rod are installed on the pointer cover plate, and there is scale label in the cover plate front on the tressel; Wherein: the axis place surface level of the plane that the center line of a pair of flange guide rail constitutes reisilometer movement during with the elastic hammer attack overlaps; Elastic stem front end direction is forward direction on the reisilometer movement on the calibrating installation to be installed in, the two ends of flange guide rail to the direction that increases stroke exceed flange stroke required in each model reisilometer foremost and rearmost end, on the pointer cover plate two ends of pointer guide rail to the direction that increases the pointer stroke exceed in each model reisilometer in the required pointer stroke foremost and rearmost end, the two ends of the maximum relative displacement stroke between tressel and base to the direction that increases stroke exceed the required stroke of each model reisilometer foremost and rearmost end; The range of power sensor is greater than the maximal value of the required range of elastic tension spring maximum pull of measuring each model reisilometer; The range of displacement transducer exceed measure the required elastic hammer stroke of each model reisilometer extension spring tensile elongation foremost with the gap length of rearmost end." one of embodiment is to have proposed the light-duty reisilometer of a kind of centering in this invention, comprises the general calibrating installation of reisilometer of three kinds of models such as M225, L75, L20.But this technical scheme is a kind of technical scheme of universality, and the relevant relevant stroke of movable stroke and part dimension all are to ask the mode of " covering " to realize the versatility of different model reisilometer to the calibrating stroke of different model reisilometer with " expansion " when operating with comparator; Because the calibrating project of three kinds of model reisilometers such as M225, L75, L20 has more general character with mechanical dimension: 1. the elastic tension spring active length is identical, 2. the elastic tension spring tensile elongation is identical, when 3. being benchmark with the resiliometer casing front end face, the position of L75, L20 type elastic hammer pointer step surface (flange guide rail, pointer cover plate scale) is identical, and than M225 type phase front (attack direction) translation 16mm, the structure of this technical scheme is still simple inadequately under these particular conditions.

Summary of the invention

At above-mentioned deficiency, just be suitable for M225, L75, three kinds of model reisilometers of L20, the utility model proposes a kind of simpler in the general calibrating installation of light-duty reisilometer, be applicable to that simultaneously traditional machinery makes the reisilometer calibrating installation.

The general calibrating installation of light-duty reisilometer is made up of base and tressel in the utility model proposes; Be connected with the tressel guide rail mechanism between tressel and the base, the two ends of the maximum relative displacement stroke between tressel and base exceed the required stroke of each model reisilometer foremost and rearmost end; On the side vertical with the tressel guide rail riveting stake is installed on the base; Have on the tressel: extension spring seat fixed mount; With a pair of flange guide rail and the support thereof that cooperate with reisilometer movement upper flange; With resiliometer casing locating device and pointer cover plate, front apron and backboard are arranged in the resiliometer casing locating device; Described extension spring seat fixed mount and front apron has and tressel between differ two fixed positions of 16mm before and after having, they and tressel relative fixed are applicable to the calibrating of M225 type reisilometer when previous position, be applicable to the calibrating of L75, two kinds of model reisilometers of L20 when the back position with the tressel relative fixed; Be the place ahead with finger direction behind when calibrating reisilometer elastic stem front end.

The general calibrating installation of light-duty reisilometer in the utility model proposes, exceed M225 at the two ends that keep the maximum relative displacement stroke between tressel and base, L75, three kinds of required strokes of model reisilometer of L20 foremost and rearmost end (about 95mm, this three models reisilometer extension spring tensile elongation is 75 mm, but wherein L20 type reisilometer elastic stem length is than long 20 mm of other two models, so the trip be about extension spring length and this elastic stem exceed length and) the basis on, with when calibrating reisilometer the relative tressel of preceding reference field (extension spring seat fixed mount front end face and housing front apron trailing flank) that the location is installed can front and back differ 16mm and fix, make the movement of three kinds of model reisilometers, after housing is installed on tressel, pointer stroke on the pointer cover plate is constant, namely the desired change to stroke and scale in the indicating value system of prior art be needn't press again, and digital reisilometer and traditional mechanical type reisilometer calibrating installation are applicable to simultaneously.Compared with prior art, structure and operation are more simple and convenient.Because the reisilometer of these 3 kinds of models is existing most popular reisilometers, therefore the utlity model has important practical value.

Described extension spring seat fixed mount and front apron are installed on the movable plate, be connected with detent mechanism between movable plate and the tressel, detent mechanism has determined to have between movable plate and the tressel front and back to differ two fixed positions of 16mm, and described detent mechanism comprises mechanical detent mechanisms such as pilot hole, location backup plate, location seat.
