Abstract
A kind of for nil-ductility temperature sample centering chalker: the sample location-plate in the sample standing groove that it is provided with by base, base, sample standing groove, the wedge shape sliding tray be arranged on centered by sample location-plate on base, be contained in the grip block in wedge shape sliding tray by wedge shaped projection, the center line on grip block forms; Center line on grip block is the shape that overlaps with the center line of sample location-plate.The sample centering that the utility model makes nil-ductility temperature test is quick, convenient, and ensure that tup just in time drops on the axis of breach when hammering, sample holder good stability, experimental result is accurate, objective, effective, for scientific research and production provide experimental result in time.
Description
Technical field
The utility model relates to the clamping device of object, specifically belongs to a kind of for nil-ductility temperature sample centering chalker.
Background technology
Nil-ductility temperature drop-weight test is the method for the nil-ductility temperature (NDT) measuring full steel plate.So-called nil-ductility temperature (NDT) temperature refers to that the maximum temperature of brittle failure occurs the steel containing crackle under dynamic load surrender, the necessary terms of delivery of the cut deal products such as Chang Zuowei bridge steel, pipe line steel.
Drop test pieces loads with the form of free beam, and sample stretches a surface build-up welding layer of brittle alloy welding bead, and opens a breach to bring out crackle.During test, sample is being cooled to uniform temperature and held for some time is placed on special anvil block, then falls weight and hits, according to sample cracking situation under different temperatures, judge nil ductility transition (NDT) temperature of material.
7.4 regulations " when installing sample, adequate measures should be taked to make sample break axis consistent with anvil block axis, and deviation is not more than 1.5mm " in GB GB/T 6803-2008.The object of this way is to ensure that tup just in time drops on the axis of breach, to ensure that the hammering energy set acts on breach when hammering.
In actual tests, nil-ductility temperature test exists following not enough: one is that the breach of sample is difficult to centering, wastes time and energy; Two is that test efficiency is low, is difficult in time for scientific research or production provide accurate and effective information; Three is test owing to often departing from center line, the authenticity of its result, and accuracy is just difficult to realize.
Utility model content
The purpose of this utility model is the deficiency overcoming prior art existence, the sample centering providing a kind of nil-ductility temperature to test is quick, convenient, ensure that tup just in time drops on the axis of breach when hammering, experimental result is accurate, effectively objective, and promptness strong for nil-ductility temperature sample centering chalker.
Realize the technical measures of above-mentioned purpose:
A kind of be used for nil-ductility temperature sample centering chalker, it is: the sample location-plate in the sample standing groove that it is provided with by base, base, sample standing groove, the wedge shape sliding tray be arranged on centered by sample location-plate on base, be contained in the grip block in wedge shape sliding tray by wedge shaped projection, the center line on grip block forms; Center line on grip block is the shape that overlaps with the center line of sample location-plate.
It is: be connected to wedge shaped projection shape on grip block and wedge shape sliding tray matching form closes.
Feature of the present utility model: the sample centering of nil-ductility temperature test is quick, convenient, ensure that tup just in time drops on the axis of breach when hammering, sample holder good stability, experimental result is accurate, objective, effective, for scientific research and production provide experimental result in time.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of grip block in Fig. 1;
In figure: 1-base, 2-sample standing groove, 3-sample location-plate, 4-wedge shape sliding tray, 5-wedge shaped projection, 6-grip block, 7-center line, 8-centering breach.
Embodiment
Be described further below in conjunction with accompanying drawing:
A kind of be used for nil-ductility temperature sample centering chalker: its by welding or the sample location-plate 3 of grafting, the wedge shape sliding tray 4 processed centered by sample location-plate 3 on base 1 in the sample standing groove 2 of processing on base 1, base 1, sample standing groove 2, be contained in the grip block 6 in wedge shape sliding tray 4 by wedge shaped projection 5, the center line 7 on grip block 6 forms; Center line 7 on grip block 6 is the shape that overlaps with the center line of sample location-plate 3.Also centering breach 8 can be processed at the sample standing groove 2 connecting sample location-plate 3 place.
For the movement behind the location of grip block 6, therefore the shape of wedge shaped projection 5 of connection on grip block 6 and the matching form of wedge shape sliding tray 4 must be made to close.
During use, the breach of sample fragility welding bead is navigated to the position of sample location-plate 3, and center line 7, even centering breach 8 on the center line of the breach of sample fragility welding bead, two grip blocks 6 are coincided together, then move grip block 6, sample is tightly clamped by two grip blocks 6; Setting-out operation is completed rapidly again according to the center line 7 on grip block 6.Need not repeatedly overturn for sample, disposable location just can complete operation.
This embodiment is only the best and exemplifies, the restricted enforcement not to technical solutions of the utility model.
Claims (2)
1., for a nil-ductility temperature sample centering chalker, it is characterized in that: the sample location-plate in the sample standing groove that it is provided with by base, base, sample standing groove, the wedge shape sliding tray be arranged on centered by sample location-plate on base, be contained in the grip block in wedge shape sliding tray by wedge shaped projection, the center line on grip block forms; Center line on grip block is the shape that overlaps with the center line of sample location-plate.
2. as claimed in claim 1 a kind of be used for nil-ductility temperature sample centering chalker, it is characterized in that: be connected to wedge shaped projection shape on grip block and wedge shape sliding tray matching form closes.
