Abstract
The utility model relates to a calibrating instrument technical field especially relates to a lever apparatus is used in calibration of torsion appearance, and it is including the support arm that is used for connecting the torsion appearance, and it still includes the dynamometry lever, dynamometry lever detachably horizontal installation in the support arm, the both ends of dynamometry lever all are provided with bubble type spirit level, and a plurality of scale grooves have still been seted up to the dynamometry lever. The lever device for calibrating the torsion meter with the structure has the advantages of simple structure, convenience in operation, capability of meeting the requirement of field calibration, and capability of meeting the requirement of a user on accuracy.
Description
Technical field
The utility model relates to the calibration instrument technical field, relates in particular to a kind of torsigraph calibration leverage.
Background technology
Torsigraph (claiming again torque force testing instrument) is mainly for detection of the fastening degree of sample and the torsional property of some parts of sample, to determine whether sample meets the torsion requirement.
Torsigraph need to be calibrated, yet, existing calibrating installation, complex structure, inconvenient operation can't realize the needs of field calibration, can not satisfy well the calibration requirements of torsigraph.
Summary of the invention
The purpose of this utility model is to provide for the deficiencies in the prior art a kind of torsigraph calibration to use leverage, and is not only simple in structure, easy to operate, can realize the needs of field calibration, and degree of accuracy can satisfy user's needs.
For achieving the above object, the utility model adopts following technical scheme: a kind of torsigraph calibration leverage, it comprises for the support arm that connects torsigraph, it also comprises the dynamometry lever, dynamometry lever removably level is installed on described support arm, the two ends of dynamometry lever are provided with bubble and scale, and the dynamometry lever also offers some scale grooves.
Distance between adjacent scale groove is 1cm.
It also comprises tie down screw, and tie down screw holds out against the dynamometry lever after passing support arm.
Described support arm offers through hole, and described dynamometry lever passes described through hole.
The utility model beneficial effect is: a kind of torsigraph calibration leverage described in the utility model, its structure is, it comprises for the support arm that connects torsigraph, it also comprises the dynamometry lever, dynamometry lever removably level is installed on described support arm, the two ends of dynamometry lever are provided with bubble and scale, and the dynamometry lever also offers some scale grooves.Leverage is used in the torsigraph calibration of employing said structure, and is not only simple in structure, easy to operate, can realize the needs of field calibration, and degree of accuracy can satisfy user's needs.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described: as shown in Figure 1, a kind of torsigraph calibration leverage described in the utility model, its structure is, it comprises for the support arm 5 that connects torsigraph 6, it also comprises dynamometry lever 2, dynamometry lever 2 removably level is installed on described support arm 5, and wherein, support arm 5 offers the through hole that passes to dynamometry lever 2.The two ends of dynamometry lever 2 are provided with bubble and scale 3, and dynamometry lever 2 also offers some scale grooves 4.
Preferably, the distance between adjacent scale groove 4 is 1cm, namely adds a scale groove 4 every 1cm, and each scale groove 4 is as a measurement point, and therefore, each counterweight can be hung a plurality of measurement points and measure, and makes measurement more accurate.Distance between certain adjacent scale groove 4 can also less than 1cm or greater than 1cm, specifically be decided according to the actual alignment precision.
A kind of torsigraph calibration described in the utility model also comprises tie down screw 1 with leverage, tie down screw 1 holds out against dynamometry lever 2 after passing support arm 5, lock or unclamp dynamometry lever 2 by turn-knob tie down screw 1, this removable structure is not only simple, and easy to operate.
During use, after hanging up counterweight, dynamometry lever 2 is turned level, counterweight power is on duty draws standard torque in dynamometry lever 2 distances by calculating, displayed value with torsigraph 6 compares again, so, can reflect exactly just whether the displayed value of torsigraph 6 is accurate, not only simple in structure, easy to operate, can realize the needs of field calibration, and degree of accuracy can satisfy user's needs.
The above is only better embodiment of the present utility model, therefore all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
