Abstract
The invention relates to a design and an application for a forcing device formed by improving a height vernier caliper. A caliper body of the height vernier caliper is rotated by 180 degrees and is fixed on a base again, so that a marking measuring jaw is dead against the base; a force sensor is arranged on the base; a cutting edge of the marking measuring jaw is removed, and a shore durometer to be measured is arranged, so that the shore durometer is dead against the force sensor (shown as an abstract attached drawing); during use, a fastening screw is loosened, the vernier caliper and the marking measuring jaw are moved, and the shore durometer is driven to move, so that the shore durometer is about to contact the force sensor, the fastening screw is tightened, and coarse tuning positioning is finished. A micro-motion device is rotated, so that the vernier caliper and the marking measuring jaw are slowly moved downwards, and the shore durometer is driven to apply a load to the force sensor. The problem that the shore durometer calibrating apparatus forcing device is difficult to design is solved, machining cost is greatly reduced, the forcing precision is guaranteed, and the shore durometer calibrating apparatus forcing device is simple in structure and convenient to use and is a perfect design of the shore durometer calibrating apparatus.
Description
Technical field the present invention relates to a kind of design and use of the augmentor transformed by vernier height gauge, belongs to technology of instrument and meter field.
Background technology Shore durometer is the measurement instrument for measuring the hardness of rubber, is a kind of measurement instrument of rubber enterprise indispensability.By the measurement to hardness, the physical property that rubber intensity, toughness, resistance to aging, wearing quality etc. are important can be reflected, to ensureing that the quality of rubber has vital effect.Therefore, the whether accurate quality being directly connected to rubber of Shore durometer, must to its periodic verification by national regulation.Be exactly Shore durometer calibrating instrument for examining and determine the reference instrument of Shore durometer.
The pressing stroke of Shore durometer amounts to 2.5mm, and be equally divided into 100 hardness numbers, hardness number and force value exist corresponding relation, and its formula is: in F=550+75HA formula, F is force value, and unit mN, HA are hardness number.Whether the force value mainly measured corresponding to its hardness number the calibrating of Shore durometer is accurate.Therefore, Shore durometer calibrating instrument is made up of augmentor and measurement mechanism.The device for measuring force that measurement mechanism is mainly made up of force snesor and digital instrument, and its afterburner system is strict owing to requiring, is the difficult point in design always.The requirement of augmentor is can coarse positioning easily in the scope of 300mm, can apply force value accurately and stably, and the force value applied is less, is (2 ~ 10) N behind location in the scope of 2.5mm.
Original augmentor is all independent processing, there is a lot of shortcoming.First be that processing cost is very high, need to process the parts such as screw mandrel, nut specially, and complete assembling; Next is that machining precision does not often reach requirement, causes afterburning unstable; That augmentor volume is comparatively large again, operation inconvenience.
Present invention utilizes the mature technology of existing instrument, the transformation of 300mm vernier height gauge is formed augmentor.
Vernier height gauge itself is a kind of precision measuringtoll, it is when measuring workpieces height, first by moving cursor chi, line measuring jaw is made to contact workpiece, then trip bolt is tightened, regulate inching gear to make line measuring jaw clamping work pieces (approximately applying the clamping force of 6 ~ 10N), then read height value.
We utilize this principle of work just, are transformed by vernier height gauge, have invented the augmentor of Shore durometer calibrating instrument.The feature utilizing vernier scale and line measuring jaw can move freely on blade, realizes the coarse positioning of augmentor, fastening by trip bolt behind location.Utilize inching gear in the stroke range of 5mm, accurately can apply the feature of test force, realize the precise and stable reinforcing of augmentor.
The present invention is by the transformation to vernier height gauge, achieve the repertoire of Shore durometer calibrating instrument augmentor, successfully solve the afterburning problem of Shore durometer calibrating instrument, significantly reduce manufacturing cost, improve afterburning precision, make whole the small and exquisite exquisiteness of equipment, convenient to use, not only can be applicable to Shore durometer calibrating instrument, also can be applicable in other similar afterburner systems.
Summary of the invention the invention is characterized in and utilizes the distinctive location of vernier height gauge and boosting function, 300mm vernier height gauge is carried out structure of modification and makes augmentor.
The blade of vernier height gauge is pulled down from base, turns 180 °, retighten on base, make line measuring jaw just to base.Processing tool, installing force sensor on base.Unclamp the screw on line measuring jaw, by the blade removal of line measuring jaw, processing tool, installs Shore durometer to be measured at former blade place, makes it with force snesor just to (see Figure of description).
Under Shore durometer to be measured being arranged on during use line measuring jaw, unclamp trip bolt, moving cursor chi and line measuring jaw on blade, the Shore durometer that drive is arranged under line measuring jaw moves, and makes Shore durometer by contact force sensor.Tighten trip bolt, coarse positioning is complete.Rotary micromotion device, makes vernier scale and line measuring jaw slowly move down, drives Shore durometer to apply force value to force snesor.When arrival first calibrating point, stop operating inching gear, reads calibrating data, then continue reinforcing, until complete the calibrating of all calibratings point, completes the calibrating to Shore durometer with this.
Tool of the present invention has the following advantages: (1) manufacture craft is simple, greatly reduces cost, compared with processing augmentor with specialized designs, and the thousands of unit of cost saving; (2) easy to use, quick; (3) reinforcing is convenient to control, precise and stable; (4) structure is simple, exquisite durable; (5) can be applied in other similar afterburner systems.
Appended drawings is the figure of the augmentor transformed by vernier height gauge.
The present invention is further described below in conjunction with Figure of description for embodiment:
The present invention is formed by the transformation of 300mm vernier height gauge.First, the blade of vernier height gauge is pulled down from base, turn 180 °, retighten on base, make line measuring jaw just to base.Then, processing tool, installing force sensor on the base of vernier height gauge, connects digital instrument composition measuring apparatus.Unclamp the screw on line measuring jaw, by the blade removal of line measuring jaw, processing tool, installs Shore durometer to be measured at former blade place, makes it just right with force snesor.
Under Shore durometer to be measured being arranged on during use line measuring jaw.Unclamp trip bolt, by push-and-pull vernier scale, vernier scale and line measuring jaw are moved with hand on blade, the Shore durometer that drive is arranged under line measuring jaw moves, until Shore durometer is by contact force sensor.Tighten trip bolt, coarse positioning is complete.Rotary micromotion device, makes vernier scale and line measuring jaw slowly move down, drives Shore durometer to apply force value to force snesor.When arrival first calibrating point, stop operating inching gear, reads the indicating value of Shore durometer and the indicating value of digital instrument, compare, it is qualified to judge whether, then continues reinforcing, until complete the calibrating of all calibratings point, complete the calibrating to Shore durometer with this.
