Description

A kind of tensile sample supplemental measurement tool
Technical field
The utility model belongs to tensile testing equipment technical field, is related to a kind of drawing to metal material mechanics performance detection Stretch sample supplemental measurement tool.
Background technology
Elongation after fracture and the contraction percentage of area are two big plasticity index in metal material mechanics performance.Break under normal circumstances Elongation and the contraction percentage of area are measured by manually mode after sample fracture afterwards, as samples cannot in measurement process Docking and positioning very well, will bring prodigious measurement error.GB/T228.1 standards provide, measure elongation after fracture and section is received Shrinkage is not less than the vernier caliper of 0.02mm using measurement accuracy, and the fracture location for the two-section sample having no progeny carefully is matched and is connected on one It rises, makes its axis on same straight line, received in sample section and measure minimum sectional area of having no progeny at neck, calculated according to formula disconnected Face shrinking percentage performance indicator;The length for measuring gauge length of having no progeny measures elongation after fracture performance indicator according to formula.This was measured Without supplemental measurement tool, two-section sample of having no progeny cannot be stitched together Cheng Ruguo well, and laboratory technician needs hand steered by one Firmly or finger clamps sample, and another hand is measured by vernier caliper.Sample shifting is easy to happen in this mode measurement process Dynamic dislocation, the axis of two-section sample are not arranged on the same straight line, and lead to accurately to measure have no progeny gauge length and minimum dimension of having no progeny, Bring very big measurement error.And due to measuring slide calliper rule itself there is certain dimensional space, sample to be placed directly on workbench, Very big inconvenience is brought in bottom without space, to measurement, influences measurement efficiency and accuracy of measurement.So if accurate quick is wanted to measure Go out the elongation after fracture and contraction percentage of area performance indicator of sample, it is necessary to a kind of applicable supplemental measurement tool is designed, it is convenient Splice the two-section sample having no progeny, and fixedly positioning spliced sample, and has enough measurement spaces, laboratory technician can accurate quick Measure the elongation after fracture and contraction percentage of area performance indicator of sample.
The Chinese utility model patent file of Publication No. CN201020265778.2 discloses a kind of round tensile sample Measure assistance platform.In terms of the data that document provides, which uses a kind of simple V-arrangement measuring table, to a certain extent Sample of having no progeny can be met, lateral displacement does not occur in measurement process, but had the following disadvantages:1. it cannot be guaranteed that sample is surveyed Vertical shift occurs during amount, brings measurement error;2. the measuring table does not measure space, cannot fast measure;3. only Suitable for round tensile sample, the measurement of plate-like rectangular sample cannot be met.
Utility model content
In order to overcome the disadvantages mentioned above of the prior art, the utility model to provide a kind of tensile sample supplemental measurement tool, it With 2 points of positioning principles in alignment, the two-section sample that fast quick-acting is had no progeny, fracture can fit like a glove, and in same On axis, it is fixedly positioning spliced sample, is not displaced when measuring.Sufficient measurement space facilitates laboratory technician can spirit It is living to complete sample measurement with vernier caliper.Laboratory technician measures the elongation after fracture of sample by this auxiliary tool energy accurate quick With contraction percentage of area performance indicator, measurement accuracy and efficiency are improved, meets big production and stretches batch detection needs.
