Description
Technical field
The present invention 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 confirmed 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 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; Drive the test specimen translation by the gear train of pedestal then, during the test specimen translation, the scriber that is provided with through the pedestal top or get pin ready and accomplish 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 through test specimen from scriber or get that translation rules successively or get ready under the pin ready, thereby accomplish the five equilibrium gauge length of test specimen, the inefficiency of therefore getting ready or ruling.Secondly, mostly existing pen machine or dotting machine are complex structure, and production cost is high, costs an arm and a leg, and make research funding nervous unit, tissue or individual be difficult to bear the great number expenditure.
Summary of the invention
The present invention 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 present invention deals 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 said base, on scriber assembly erecting frame, is provided with trepanning corresponding to loop bar position, location, and scriber assembly erecting frame is sleeved on the loop bar of location through trepanning, and can on loop bar, slide up and down; Said 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 said scriber assembly is made up of syringe needle, syringe needle connector, spring part and top screw; Said 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 invention also is: it is 11 that said scriber is installed threaded hole.
Said baffle plate is provided with the bolt that limits the test specimen endpoint location, said bolt through with the baffle plate thread connection.
Compared with present technology, beneficial effect of the present invention is embodied in:
1, the present invention is provided with a plurality of scribers, and 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 was carried out the five equilibrium gauge length, test specimen was stuck in the V-type groove of base, and one of test specimen is against on the postive stop baffle; The other end is by manual rotation or drive device drives rotation, and the scriber assembly receives 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 rotates; 11 syringe needles are rule on test specimen simultaneously; When test specimen is rotated a circle, just accomplish the five equilibrium gauge length of test specimen, use very convenient.
2, scriber assembly of the present invention is that elastic force, scriber assembly erecting frame and self gravitation effect through 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 five equilibrium gauge length of disposable completion as long as rotate test specimen, improved its work efficiency greatly test specimen.
3, the loop bar that is provided with on the base of the present invention 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.
