Abstract
The utility model discloses a be used for small -size hardness sample measuring clamping frock, the clamping frock be circular or the rectangle structure, be provided with the location mounting hole more than 6 in the clamping frock, the location mounting hole be screw through -hole or round pin shaft hole, when the location mounting hole for round pin during the shaft hole, the side of selling the shaft hole be provided with with the screw hole of selling the perpendicular intercommunication in shaft hole, be provided with fastening screw at threaded hole. The utility model discloses with hardness sample centralized system appearance and detection, replaced among original hardness detection method the mode that can only the separate room detects, improved detection efficiency greatly, reduced measurement personnel's working strength, solved earlier stage small -size hardness sample preparation and measurement process speed extremely slowly, shortcomings such as loaded down with trivial details, the inefficiency of step.
Description
Technical field
The utility model relates to a kind of clamping tooling measured for small-sized hardness specimens, belongs 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.
Utility model content
The purpose of this utility model is, provide a kind of simple to operate, convenient mounting and clamping, the clamping tooling measured for small-sized hardness specimens that detection efficiency is high, to overcome the deficiencies in the prior art.
The technical solution of the utility model: a kind of clamping tooling measured for 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.
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.
Further, the mouth rim in aforesaid location and installation hole is provided with numbering.
Owing to adopting technique scheme, the utility model has the advantage of: hardness specimens is concentrated sample preparation and detection by the utility model, 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.

Embodiment
In order to make the utility model object, technical scheme and advantage clearly, below in conjunction with drawings and Examples, the utility model is described in further detail.
Implement one
As shown in Figures 1 and 2, a kind of clamping tooling measured for small-sized hardness specimens of the present utility model, described clamping tooling 1 is circular configuration, clamping tooling 1 is provided with 14 location and installation holes 2, described location and installation hole 2 is tapped through hole, and the mouth rim in aforesaid location and installation hole 2 is provided with numbering, be convenient to distinguish record.
During measurement, see Fig. 3, first the clamping tooling 1 being covered with location and installation hole 2 is placed on backing plate 4, then by hardness specimens (bolt, screw or stud) screw on clamping tooling 1 location and installation hole 2, and using the upper surface of backing plate 4 as benchmark, each hardness specimens is fixed on clamping tooling 1, then clamping tooling 1 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 1 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 1.
Implement two
As shown in Figures 4 and 5, a kind of clamping tooling measured for small-sized hardness specimens of the present utility model, described clamping tooling 1 is rectangular configuration, and clamping tooling 1 is provided with 8 location and installation holes 2, and the mouth rim in aforesaid location and installation hole is provided with numbering, be convenient to distinguish record; Described location and installation hole 2 is pin shaft hole, is provided with the threaded hole with pin shaft hole vertical connection, is provided with trip bolt 3 in threaded hole in the side of pin shaft hole.
During measurement, see Fig. 6, first the clamping tooling 1 being covered with location and installation hole 2 is placed on backing plate 4, then hardness specimens (bearing pin or rivet) is inserted in the location and installation hole 2 on clamping tooling 1, and using the upper surface of backing plate 4 as benchmark, trip bolt 3 is adopted to be fixed on clamping tooling 1 by each hardness specimens, then clamping tooling 1 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 1 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 1.
