Description
Technical field
The utility model relates to a kind of augmentor of measurement and calibration, is specifically related to the afterburning platform of a kind of universal measurement and calibration, belongs to special measurement testing of equipment technical field.
Background technology
In measurement and calibration process to the load dynamometric system, the sensor and the proof force value sensor string of dynamometric system need be connected together, simultaneously two cover dynamometric systems are applied identical pressure or pulling force then, because two dynamometric systems are cascaded, so in theory, the power value of two dynamometric system demonstrations should equate, but since measuring system the precision of ratio of precision proof force sensor on the low side, certain error is arranged relatively, by two power Value Data comparisons, thereby calculate this error.
To the device of dynamometric system sensor and the reinforcing of proof force sensor, be exactly afterburning platform.At present, metering mechanism's afterburning platform commonly used all is to use bearing that the angular displacement of rotary spanner is converted into vertical displacement of the lines, but bearing is for being rigidly connected, like this at afterburning platform when deviation appears a little in centering, afterburning axis centre is not just on same straight line, generation is with the moment of torsion of power value equidirectional, make dynamometric system or standard can accurately not reflect acting force, the shearing force that produces will influence the accuracy of measurement and calibration data, and generally speaking, this error is very little, be negligible, but for measurement and calibration, data precision is had relatively high expectations, so should reduce the deviation that causes in the power value transmittance process as far as possible.
The utility model content
The utility model has designed a kind of, and the technical matters of its solution is: in the measurement and calibration process to the load dynamometric system, get rid of the influence to continuous data of shearing force that afterburning platform do not produce owing to afterburning axis centre when reinforcing on same straight line.
In order to solve the technical matters of above-mentioned existence, the utility model has adopted following scheme:
The afterburning platform of a kind of universal measurement and calibration mainly is made up of boosting mechanism, be installed mechanism and fixed mechanism.Wherein, boosting mechanism comprises: handwheel, afterburning push rod and Universal-head; The described mechanism that is installed comprises: pressing plate, copper sheathing and joint boot; Described fixed mechanism comprises: fixed base plate, pillar, supporting seat and thread bush.
Further, described supporting seat is connected with the upper end of two pillars, and the supporting seat middle part connects described thread bush, and described afterburning pull bar is threaded with fixed mechanism by described thread bush.
Further, the pressing plate of the described mechanism that is installed carry out non-rigid the connection by described copper sheathing with described pillar, by copper sheathing the described mechanism that is installed can be slided up and down along described pillar, described joint boot is arranged on the pressing plate middle part
Further, described Universal-head is connected the bottom of boosting-rod, is deep in the described joint boot space packing lubrication agent in the middle of Universal-head and the joint boot.
Further, described joint boot is connected with the different sensors adaptor by bolt, the different force transducer of corresponding connection.
Further, described Universal-head profile is spherical.
Further, described fixed base plate has a center pit, to make things convenient for the connection of force transducer.
This has following beneficial effect: when proof force sensor and dynamometric system are added pulling force, rotation hand wheel by the straight-line displacement of afterburning push rod, applies pulling force to dynamometric system sensor and proof force sensor, universal conversion joint is inner by lubricant, can not produce lateral shift.In addition, for guaranteeing that dynamometric system is not subjected to revolving force, added the mechanism that is installed.Can when applying pulling force, guarantee power value Axis Consistency like this, get rid of that make that data are more accurate, the metering result is codes and standards more owing to afterburning axis centre does not produce the influence of shearing force to continuous data on same straight line.The utility model equipment is simple, and the transmission of power value is accurate, has solved a domestic insurmountable calibration difficult problem

Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
At first, by Fig. 1 and Fig. 2 the technical matters that the utility model solved is described.Fig. 1 and Fig. 2 are that universal afterburning platform produces error by principle figure.When the direction of dynamometric system and pressure apparatus acting force during at same straight line, as shown in Figure 1, tie rod ball blocks axle sleeve, and acting force is added to total system.But all there is certain deviation in the connection of any afterburning platform, when the acting force center line has when necessarily departing from, as shown in Figure 2, tie rod ball is extrusion lubricant accordingly, make the stress point skew, at this moment can produce a shearing force, thereby bring the error of force measurement, the degree of accuracy of continuous data is exerted an influence.
Fig. 3 is each modular construction of the utility model and connection diagram.The utility model comprises three mechanisms: boosting mechanism, mechanism and fixed mechanism are installed.
Described boosting mechanism comprises: handwheel 3, afterburning push rod 4 and Universal-head 5.By rotation hand wheel 3, with Hand-wheel spanner angular displacement be converted into the straight-line displacement of afterburning push rod 4, by the change of displacement, dynamometric system and proof force sensor are applied pulling force, so handwheel 3 and afterburning push rod 4 are afterburning source.The push rod bottom is the Universal-head 5 of a sphere, and 8 li of cover joint boots below, and packing lubrication agent 15 play the connection effect.
The described mechanism that is installed comprises: pressing plate 6, copper sheathing 7 and joint boot 8.The pressing plate 6 of mechanism of being installed is installed on the pillar 10, but be non-rigid the connection with 10 on pillar, can slide up and down along pillar 10 by copper sheathing 7, the joint boot 8 of the mechanism that is installed connects various adaptors 13 by bolt, the various force transducer 14 of corresponding connection.
