Description
Technical Field
The utility model belongs to the technical field of mechanics detects technique and specifically relates to a gauge length measuring supplementary anchor clamps after test bar breaks.
Background
The tensile test bar is made of a plate or a flat material with the thickness of more than or equal to 3mm or a wire or a bar material with the diameter or the thickness of more than or equal to 4 mm. When the bar is adopted, after the test bars are subjected to a tensile test, two broken test bars need to be spliced again, and the distance change of two mark points on the cylindrical test bars is measured. Because the test bar fracture after the fracture is inhomogeneous, and the test bar both ends exposed core is thick, can't keep flat, and single is difficult to accomplish the operation.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: in order to overcome the defects in the prior art, the auxiliary clamp for measuring the gauge length after the test bar is broken is provided.

The clamping part of the clamping plate adopts a V-shaped groove structure, so that the concentricity of the two broken test bars after clamping and splicing is ensured; the sectional V-shaped groove structure is adopted, so that the fracture of the cylindrical test rod is not clamped during clamping, and the distance error caused by clamping is further reduced; most cylinder test bars are exposed when the degree of depth of control V type groove structure is ensured to the centre gripping, and with the outside centre gripping location of the index point of cylinder test bar during centre gripping simultaneously, use slide caliper to measure after the centre gripping of being convenient for, reach the convenient and accurate of gauge length measurement after the test bar breaks.
The connecting part of the two clamping plates is provided with a hole matched with the central shaft, so that the two clamping plates are prevented from offsetting during clamping, and the distance error caused by clamping is further reduced.
The clamping plate adopts a T-shaped structure, so that the structure is attractive and the operation is convenient.
The sectional type gaps on the side edges of the V-shaped groove structures of the clamping parts are of triangular, semicircular or rectangular structures which are continuously and uniformly distributed. Set up the breach for the fracture of cylinder test-bar is not cliied when the centre gripping, further reduces the distance error that the centre gripping caused.
The utility model discloses a when the test bar is disconnected back gauge length measuring supplementary anchor clamps use, two grip blocks are under the effect of center pin and spring, with the outside centre gripping concatenation location of the index point of two sections fracture cylinder test bars, then use slide caliper to carry out the gauge length and measure.
The utility model has the advantages that: the utility model discloses an auxiliary clamp for measuring the gauge length after the test bar is broken, the clamping part of the clamping plate adopts a V-shaped groove structure, and the concentricity of two test bars after being clamped and spliced after being broken is ensured; the sectional V-shaped groove structure is adopted, so that the fracture of the cylindrical test rod is not clamped during clamping, and the distance error caused by clamping is further reduced; most cylinder test bars are exposed when the degree of depth of control V type groove structure is ensured to the centre gripping, and with the outside centre gripping location of the index point of cylinder test bar during centre gripping simultaneously, use slide caliper to measure after the centre gripping of being convenient for, reach the convenient and accurate of gauge length measurement after the test bar breaks.
