Description

The tensile test specimen pen machine
Technical field
The utility model relates to a kind of being applied in the tension test, test specimen length is carried out the pen machine of five equilibrium gauge length.
Background technology
Tension test is meant the test method of measuring material behavior under the axial tension load bearing.The data of utilizing tension test to obtain can be determined elastic limit of materials, elongation between gages rate, elastic modulus, proportional limit, reduction of area, tensile strength, yield point, yield strength and other tensile property index.When doing tension test, at first need to use pen machine or dotting machine that the test specimen length of tension test is carried out the five equilibrium gauge length, pen machine or dotting machine commonly used at present all are that test specimen is fixed on the pedestal of equipment, gear train by pedestal drives the test specimen translation then, during the test specimen translation, the scriber that is provided with by pedestal top or get pin ready and finish at branch gauge lengths such as test specimens.Because the scriber of existing pen machine or get pin ready and only be provided with, it be by test specimen from scriber or get under the pin translation ready and rule successively or get ready, thereby finish the five equilibrium gauge length of test specimen, the therefore inefficiency of getting ready or ruling.Secondly, mostly existing pen machine or dotting machine are complex structure, and the production cost height costs an arm and a leg, and make unit, tissue or the individual of research funding anxiety be difficult to bear the great number expenditure.
The utility model content
The utility model is for fear of above-mentioned existing in prior technology weak point, provide a kind of simple in structure, with the five equilibrium gauge length pen machine of many scribers, realize disposable multiple spot line gauge length to test specimen.
It is to adopt following technical scheme that the utility model is dealt with problems:
Tension test usefulness waits branch gauge length pen machine, comprises base, is arranged at the scriber assembly erecting frame and the scriber of base top, and its design feature is:
The diagonal angle is provided with the location loop bar on the described base, is provided with trepanning corresponding to loop bar position, location on scriber assembly erecting frame, and scriber assembly erecting frame is sleeved on the loop bar of location by trepanning, and can slide up and down on loop bar; Described scriber assembly erecting frame is horizontally arranged with an evenly distributed scriber threaded hole is installed, and each scriber is installed on the threaded hole scriber assembly is housed, and described scriber assembly is made of syringe needle, syringe needle connector, spring part and top screw; Described syringe needle connector and scriber assembly mounting hole are flexible rod-type draw bail, on base under the scriber syringe needle indication, also be provided with and limit the V-type groove that test specimen moves radially, be provided with in a horizontal end of base simultaneously and limit the axially movable baffle plate of test specimen.
Design feature of the present utility model also is: it is 11 that described scriber is installed threaded hole.
Described baffle plate is provided with the bolt that limits the test specimen endpoint location, described bolt by with the baffle plate thread connection.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the utility model is provided with a plurality of scribers, scriber is separately fixed on the scriber assembly erecting frame, and scriber assembly erecting frame and base can freely slide up and down, when test specimen is carried out the five equilibrium gauge length, test specimen is stuck in the V-type groove of base, one of test specimen is against on the postive stop baffle, the other end is by manual rotation or drive unit driven rotary, the scriber assembly is subjected to the action of gravity syringe needle of scriber assembly erecting frame to drop on the test specimen automatically and is evenly distributed, when test specimen rotated, 11 syringe needles were rule on test specimen simultaneously, when test specimen is rotated a circle, just finish the five equilibrium gauge length of test specimen, use very convenient.
2, scriber assembly of the present utility model is that elastic force, scriber assembly erecting frame and self gravitation effect by its spring part combines, make the needle section potential energy keep closely contacting with the test specimen periphery all the time, thereby get final product the disposable five equilibrium gauge length of finishing test specimen as long as rotate test specimen, improved its work efficiency greatly.
3, the loop bar that is provided with on the utility model base is the diagonal angle setting, forms the plane and two pits location, and assurance pen machine upper body and lower body are accurately located, thereby guarantees the accuracy of scriber to the five equilibrium gauge length of test specimen.
