Description
Technical field
A kind of sclerometer of the utility model design, relate in particular to a kind of novel Wechsler hardness tester.
Background technology
The hard steel pressing of Wechsler hardness tester principle definite shape, be pushed down into specimen surface in the effect of standard spring test force, with the compression distance of pressing, determines material hardness, and the compression distance of definition 0.01mm is a webster hardness unit.The webster hardness unit representation is HW.
Wechsler hardness tester is used for aluminium alloy series products webster hardness value and measures, Wechsler hardness tester is the small portable instrument, its volume is little, lightweight, one-hand operation, can be fast, convenient, test material hardness nondestructively, it needn't be taken a sample, less demanding to operative skill, be very suitable for, in production scene, material is carried out quick hardness and detect.The shortcoming of Wechsler hardness tester is that sensitivity is poor, and range is narrower, and gamut only has 20 scales, and therefore a common instrument can only be tested 1～2 kind of metal material.
Wechsler hardness tester adopts two kinds of difform pressings, two kinds of different test forces, and their instrument that constitutes three kinds of different models, be respectively used to test aluminium alloy, soft copper, hard copper, extra super duralumin alloy and mild steel.Wechsler hardness tester is suitable for testing the material with two parallel surfaces, for example tubing, sheet material and section bar, and the material thickness maximum can reach 13m.
Wechsler hardness tester is very suitable for that in production scene product is in batch pursued part and detects, let it be to the greatest extent, and sensitivity is not high, but can meet the demands as production control and qualification determination instrument, just because of this reason, Wechsler hardness tester has obtained application quite widely in the aluminium processing industry.
The utility model content
For the not enough the utility model that solves above technology provides a kind of novel Wechsler hardness tester.
In order to realize above-mentioned technical purpose, scheme of the present utility model is a kind of novel Wechsler hardness tester, comprise back-moving spring, measuring seat, pressing, spring, pressing sleeve, setting nut, reading mechanism, boosting-rod, reset key, supporting screw, framework, described boosting-rod is fixed on framework by supporting screw, boosting-rod is connected with the pressing in the middle of the reading mechanism that is arranged on hollow, and described reading mechanism is arranged on described pressing sleeve; Install and be provided with setting nut, spring, pressing respectively from top to bottom in described pressing sleeve.
Described reset key is connected with the pressing sleeve simultaneously, is provided with back-moving spring below reset key.
Described framework, boosting-rod, measuring seat, pressing sleeve, setting nut, reset key are aluminum alloy materials.
The pressing of spring and definite shape is put in the pressing sleeve, by boosting-rod drive sleeve team sample, applied certain test force, logical indicating mechanism directly shows the webster hardness value to the measurement of pressing displacement.
The utility model is to use the pressing of the Spring driving definite shape of certain rigidity to carry out the webster hardness measurement to sample, and measurement result is directly read by indicating mechanism.The most approximate scheme is to substitute spring with other elastic bodys, with the digital display type reading mechanism, replaces pointer reading mechanism.
The beneficial effects of the utility model are: the utility model long service life, be easy to carry, and the spring force size can regulate, and convenient for users to use, improved user satisfaction.
