Abstract

The utility model relates to a loading device for a shore durometer verification apparatus. A height vernier caliper is transformed into the loading device for the shore durometer verification apparatus. A caliper body of the height vernier caliper is rotated 180 degrees, and then fixed on the base again, and a lineation measuring jaw directly faces the base. A force sensor is arranged on the base. A blade of the lineation measuring jaw is dismounted, and the shore durometer to be detected is mounted directly facing the force sensor. When the loading device for the shore durometer verification apparatus is in use, a fastening screw is loosened, moving of the vernier caliper and the lineation measuring jaw drives the shore durometer to move and about to contact the force sensor, and then fastening screw is fastened so that rough adjustment and positioning is finished. Through rotation of a mocromotion device, the vernier caliper and the lineation measuring jaw slowly move downwards, and the shore durometer is driven to exert load on the force sensor. The loading device for the shore durometer verification apparatus solves the problem of difficult design, greatly reduces processing cost, guarantees loading accuracy and is simple in structure and convenient to use and is a perfect design suitable for the shore durometer verification apparatus.

Description

The loading system of Shore durometer calibrating instrument
Technical field the utility model relates to a kind of Shore durometer calibrating instrument loading system, belongs to the technology of instrument and meter field.
The background technology Shore durometer is to be used for measurement instrument that the hardness of rubber is measured, is the indispensable a kind of measurement instrument of rubber enterprise.Through measurement to hardness, can reflect important physical properties such as rubber intensity, toughness, resistance to aging, wearing quality, the quality that guarantees rubber is had crucial effects.Therefore, the whether accurate quality that is directly connected to rubber of Shore durometer, pressing national regulation must be to its periodic verification.The reference instrument that is used to examine and determine Shore durometer is exactly the Shore durometer calibrating instrument.
The pressing stroke of Shore durometer amounts to 2.5mm, is equally divided into 100 hardness numbers, and there are corresponding relation in hardness number and power value, and its formula is: F is the power value in the F=550+75HA formula, and the mN of unit, HA are hardness number.Calibrating to Shore durometer mainly is whether the pairing power value of its hardness number of measurement is accurate.Therefore, the Shore durometer calibrating instrument is made up of loading system and measurement mechanism.The device for measuring force that measurement mechanism mainly is made up of force transducer and digital instrument, and its loading system is the difficult point in the design owing to strict always.The requirement of loading system is can coarse positioning easily in the scope of 300mm, and the back, location can apply load accurately and stably in the scope of 2.5mm, and the load that applies is less, is (2~10) N.
Original loading system all is independent processing, has a lot of shortcomings.At first be that processing cost is very high, need parts such as special processing screw mandrel, nut, and accomplish assembling; Next is that machining precision does not often reach requirement, causes loading unstable; Be that the loading system volume is bigger once more, operation inconvenience.
The utility model has utilized the mature technology of existing instrument, and the transformation of 300mm vernier height gauge is formed loading system.
Vernier height gauge itself is a kind of precision measuringtoll, and it is when the measuring workpieces height, at first through the moving cursor chi; Make line measuring jaw contact workpiece; Tighten trip bolt then, regulate inching gear and make line measuring jaw clamping work pieces (approximately applying the clamping force of 6~10N), read height value then.
We utilize this principle of work just, and vernier height gauge is transformed, and design the loading system of Shore durometer calibrating instrument.Utilize vernier scale and the characteristics that the line measuring jaw can move freely on blade, realize the coarse positioning of loading system, the back, location is fastening by trip bolt.Utilize inching gear can in the travel range of 5mm, accurately apply the characteristics of test power, realize the precise and stable loading of loading system.
The utility model has been realized the repertoire of Shore durometer calibrating instrument loading system through the transformation to vernier height gauge, has successfully solved the loading problem of Shore durometer calibrating instrument; Greatly reduced manufacturing cost; Improved the loading precision, made whole the small and exquisite exquisiteness of equipment, convenient to use; Not only can be applicable to the Shore durometer calibrating instrument, also can be applicable in other similar loading systems.
Utility model content the utility model is characterised in that and utilizes distinctive location of vernier height gauge and loading function, the 300mm vernier height gauge is carried out the loading system that structure of modification is processed the Shore durometer calibrating instrument.
The blade of vernier height gauge is pulled down from base, turned 180 °, retighten on base, make the line measuring jaw over against base.Processing tool, installing force sensor on base.Unclamp the screw of line on the measuring jaw, with the blade removal of line measuring jaw, processing tool, Shore durometer to be measured is installed at the place at former blade, make it with force transducer over against (seeing Figure of description).
During use Shore durometer to be measured is installed under the line measuring jaw, unclamps trip bolt, moving cursor chi and line measuring jaw on blade drive the Shore durometer that is installed under the line measuring jaw and move, and make Shore durometer be about to contact force sensor.Tighten trip bolt, coarse positioning finishes.The rotary micromotion device slowly moves down vernier scale and line measuring jaw, drives Shore durometer force transducer is applied load.When arriving first calibrating point, the inching gear that stops operating reads the calibrating data, continues loading then, until the calibrating of accomplishing all calibrating points, accomplishes the calibrating to Shore durometer with this.
The utlity model has following advantage: (1) manufacture craft is simple, has greatly reduced cost, compares the thousands of units of cost saving with specialized designs processing loading system; (2) easy to use, quick; (3) control is convenient in loading, and is precise and stable; (4) simple in structure, exquisite durable; (5) can be applied in other similar loading systems.
Appended drawings is the figure of Shore durometer calibrating instrument loading system.
Embodiment further specifies the utility model below in conjunction with Figure of description:
The utility model is formed by the transformation of 300mm vernier height gauge.At first, the blade of vernier height gauge is pulled down from base, turned 180 °, retighten on base, make the line measuring jaw over against base.Then, processing tool, installing force sensor on the base of vernier height gauge connects the digital instrument composition measuring apparatus.Unclamp the screw of line on the measuring jaw, with the blade removal of line measuring jaw, processing tool, Shore durometer to be measured is installed at the place at former blade, make it with force transducer over against.
During use Shore durometer to be measured is installed under the line measuring jaw.Unclamp trip bolt, through the push-and-pull vernier scale vernier scale and line measuring jaw are moved on blade, drive the Shore durometer that is installed under the line measuring jaw and move, be about to contact force sensor until Shore durometer with hand.Tighten trip bolt, coarse positioning finishes.The rotary micromotion device slowly moves down vernier scale and line measuring jaw, drives Shore durometer force transducer is applied load.When arriving first calibrating point, the inching gear that stops operating reads the indicating value of Shore durometer and the indicating value of digital instrument; Compare, it is qualified to judge whether, continues loading then; Until the calibrating of accomplishing all calibrating points, accomplish calibrating to Shore durometer with this.
