At present on the market to the dynamometry part Shortcomings of nonstandard testing machine, as calibration value is unstable, volume is heavy, carry inconvenience, equipment applicability is low, cause erroneous judgement probability higher.
Summary of the invention
The utility model is for overcoming at least one defect described in above-mentioned prior art, and provide portable calibrating device for pull pressure sensor, this jig Design is portable, practical with conveniently adjust centre of gravity place, thus bear the Impact direction of different instrument.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: portable calibrating device for pull pressure sensor, wherein, comprise base, the screw mandrel location division be located on base, the screw mandrel that is connected with screw mandrel location division; Described screw mandrel one end connects trapezoidal push-pull dynamometry portion, and other end connection function bar, trapezoidal push-pull dynamometry portion is provided with supporting seat.
In the utility model, user acts on screw mandrel by actuating rod, be provided with the screw thread coordinated with screw mandrel in screw mandrel location division, screw mandrel can promote trapezoidal push-pull dynamometry portion by transverse shifting, supporting seat can be driven to move up or down during trapezoidal push-pull dynamometry portion's transverse shifting.Supporting seat is placed detected force snesor and standard force-measuring sensor.
Therefore, this portable calibrating device for pull pressure sensor, adopt the direct method of measurement, detected force snesor is directly connected with portable calibrating device for pull pressure sensor with standard force-measuring sensor, and fixture slowly pressurizes, and reaches the test point of needs.
Further, described base is provided with guide rail, and trapezoidal push-pull dynamometry portion to be located on guide rail and along guide rail transverse shifting.Described base is also fixed with guide pole, and supporting seat is through guide pole and along guide pole vertically movement.Described top, trapezoidal push-pull dynamometry portion is provided with the first inclined-plane, and supporting seat bottom is provided with the second inclined-plane, and the first inclined-plane contacts with the second inclined-plane.
In the utility model, trapezoidal push-pull dynamometry portion is on guide rail during transverse shifting, and the first inclined-plane contacts with the second inclined-plane and coordinates, and supporting seat can be driven to move up or down along guide pole, and fixture slowly pressurizes, and reaches the test point of needs.
In the ordinary course of things, during all kinds of non-nonius instrument dynamometry calibration, correcting mechanism is all directly put into dynamometry standard and is calibrated.And these class methods generally need the test motor starting instrument, when directly using motor reinforcing to calibrate, relatively easy generation is produced unexpected.
This jig Design compact, light is feature, conveniently takes curstomer's site to and carries out calibration operation.Unit clamp is on the market installed on a sensor, and preliminary work is by the time of at substantial.And the utility model be devoted to develop can simultaneously for thrust and pulling force calibration operation.Also not starting directly afterburning calibration under instrument motor, production safety can be improved widely, lowering apparatus probability of failure.
So according to the content of each parameter of multiple nonstandard testing machine, develop portable calibrating device for pull pressure sensor, reduce or avoid the limitation running into various model mark testing machine in calibration operation, this portable calibrating device for pull pressure sensor will cover all kinds of pull pressure sensor field calibration.
Compared with prior art, beneficial effect is: the utility model jig Design is portable, practical with conveniently adjust centre of gravity place, thus bear the Impact direction of different instrument.Utilize trapezoidal push-pull dynamometry portion, directly to utilize screw mandrel to carry out the fixture of push-pull effort calibration relative laborsaving with all the other prior aries.And the dynamometer clamp seldom having thrust and pulling force to unify on the market, there is the fixture volume of push-and-pull two kinds of functions general comparatively large, be inconvenient to carry.This fixture small volume, is convenient for carrying.
