Abstract

The invention discloses a measurement method of small hardness sample and clamping fixture. The method comprises: first placing a clamping fixture full with positioning and mounting holes on a backing plate, clamping the hardness samples separately in the positioning and mounting holes, fixing every hardness sample on the clamping fixture on basis of the upper surface of the backing plate, clamping and fixing the clamping fixture on a polish-grinding machine and polishing and grinding the end surface to be measured of the hardness sample, placing the clamping fixture on the table of the hardness test machine, and then measuring one by one the end surface of the hardness sample to be measured on the clamping fixture and recording results. In the invention, the hardness samples are made and measured together, while the original method for hardness measurement is only in a single measurement style, measurement efficiency is largely promoted, work intensity of the personnel is lowered, and defects of slow speed, trivial steps and low efficiency for the measurement and preparation of hardness samples in the prior art is solved.

Description

A kind of measuring method of small-sized hardness specimens and clamping tooling
Technical field
The present invention relates to a kind of measuring method and clamping tooling of small-sized hardness specimens, belong to hardness measurement technical field.
Background technology
The fastener products major part of producing due to China is all smaller, as the bolt that specification is less than 8, screw, stud, stud, bearing pin and rivet etc., all require to entrust hardness determination in thermal treatment and total inspection operation, wherein a part also will be demanded perfection inspection, and original hardness detection method can only pass through polishing piecemeal, polishing, cleaning, dry up, test, make the preparation of sample and measuring process speed and slowly, and complex steps, elapsed time is many, the features such as efficiency is low, simultaneously because the size of sample is less than normal, the depth of parallelism and the surface smoothness of guarantee two parallel end faces is difficult in sample making course, make can not accurately locate in measurement, survey data out of true.
Summary of the invention
The object of the invention is to, provide a kind of simple to operate, convenient mounting and clamping, the measuring method of the small-sized hardness specimens that detection efficiency is high and clamping tooling, to overcome the deficiencies in the prior art.
Technical scheme of the present invention: a kind of measuring method of small-sized hardness specimens, first the clamping tooling one being covered with location and installation hole is placed on backing plate, then by hardness specimens respectively the location and installation hole of clamping on clamping tooling, and using the upper surface of backing plate as benchmark, each hardness specimens is fixed on clamping tooling, then clamping tooling clamping is fixed on polished machine and grinding and polishing is carried out to the tested end face of all hardness specimens, finally clamping tooling is placed on the worktable of hardness tester, can measure one by one and record the tested end face of each hardness specimens on clamping tooling.
The mouth rim in aforesaid location and installation hole is provided with numbering.
Aforesaid hardness specimens bolt, screw, stud, bearing pin or rivet.
Simultaneously, the invention also discloses a kind of clamping tooling of the measuring method for above-mentioned small-sized hardness specimens, described clamping tooling is circular or rectangular configuration, and clamping tooling is provided with the location and installation hole of more than 6, and described location and installation hole is tapped through hole.
Further, aforesaid location and installation hole is pin shaft hole, is provided with the threaded hole with pin shaft hole vertical connection, in threaded hole, is provided with trip bolt in the side of pin shaft hole.
Owing to adopting technique scheme, the invention has the advantages that: hardness specimens is concentrated sample preparation and detection by the present invention, instead of in original hardness detection method can only the mode that detects of separate room, substantially increase detection efficiency, reduce the working strength of testing staff, solve early stage small-sized hardness specimens preparation and measuring process speed extremely slow, complex steps, elapsed time is many, the shortcomings such as efficiency is low, solve due to less than normal the brought sample preparation of the size of sample simultaneously and measure difficulty, ensure that the depth of parallelism and the surface smoothness of two parallel end faces in sample making course, for the measurement data of sample provides guarantee, reduce experimentation cost, improve detection efficiency.
