Abstract
The utility model provides a test sample fixture used for an impact test, which comprises clamping pieces, a spring, an illuminating lamp and a cuboid locating block; the top ends of the upper parts of the two clamping pieces are fixedly connected; the spring is arranged on the middle parts of the two clamping pieces; the cuboid locating block is mounted at the bottom of the clamping piece at one side; the wide side of the locating block is provided with a boss matched with a gap of an impact test sample; and the illuminating lamp is arranged between the upper parts of the two clamping pieces. Compared with the prior art, cooperation of the left hand and right hands is not needed; a flashlight is not needed additionally and a locating device is not used additionally when an operator implements an impact test; therefore, not only the dangers brought to the operator and caused by narrow space of a test machine can be reduced, but also the working intensity can be lightened. The test sample fixture used for the impact test has the advantages of safety and convenience for operation, high locating precision and working efficiency improvement.
Description
Technical field
The utility model relates to a kind of national literature experiment apparatus, specifically is a kind of test fixture that is used for the laboratory impulse test.
Background technology
Impulse test is commonly used to the shock resistance of test material, is one of Experiments of Machanics chamber conventional sense project, and the sample that is used to do impulse test is a rectangular parallelepiped, and its specification has following three kinds: 10mm * 10mm * 55mm; 5mm * 10mm * 55mm; 7.5mm * 10mm * 55mm; Have U type or v-notch in the centre position on its narrow limit; When doing impulse test, be that sample accurately is positioned on the anvil block of testing machine, place that the impact pendulnm of eminence is disposable to be fallen from eminence; The strike sample has the back side of breach, measures the impact energy that sample absorbs.
In impulse test, the location of sample is very important, and bearing accuracy directly influences test findings.Generally, when doing impulse test, operator's left hand is held locating piece, and the right hand takes out sample with tweezers from cryostat,, and the right-hand man cooperates, and the sample location is placed on the anvil block of testing machine.Because the testing machine space is narrow and small, and sample was fetched into the time requirement of strike fracture within 20 seconds from cryostat,, so this locator meams is a kind of coarse localization method, was difficult to exactly sample is positioned at desired position.In addition, normally series of temperatures test of impulse test is about to sample and places the cryostat, with the alcohol cooling, and alcohol can become muddy below-60 ℃, and the operator obscures sample when the gripping sample sometimes, the test findings that directly leads to errors.For these reasons, it is high to need to propose a kind of bearing accuracy, and the test instrument of handled easily satisfies the needs that daily detection is tested.
Domestic each laboratory also not about both having can be used for the sample location in the impulse test, can be used for the accurately introduction of the specimen holder of gripping sample from the alcohol trough of obscuring again at present.Therefore, develop a kind of comprehensive specimen holder and satisfy the test needs, have practical significance.
The utility model content
The utility model is the problem that exists during to above-mentioned laboratory impulse test, and a kind of specimen holder that is used for impulse test is provided, and this specimen holder has the characteristics of bearing accuracy height, multi-functional, handled easily.
The utility model solves the technical scheme that its technical matters adopted:
The utility model is made up of two intermediate plates and spring; Two intermediate plate upper end are fixedly connected; A spring is placed at its two intermediate plate middle parts; Wherein side intermediate plate bottom is equipped with the rectangular parallelepiped locating piece, has the boss that matches with the impact specimen breach on the locating piece broadside, and an illuminating lamp is set between the two intermediate plate tops.
Have slideway on two intermediate plates of the utility model, spring end is installed in the slideway, and spring keeps intermediate plate to be in normally open, and can in slideway, move.
The effect that the utility model is useful is:
Because the intermediate plate of specimen holder middle part is placed with movably spring, therefore, different test operation persons according to individual's operating habit, can adjust the position of spring on intermediate plate, makes rapid operation, convenient; Because spring is between two intermediate plates,, be convenient to the gripping sample so two intermediate plates keep normally open; After the groove fit of the boss of rectangle locating piece on the intermediate plate and impact specimen is good, sample is taken out from cryostat,, place locating piece between two anvil blocks, easily sample is positioned on the anvil block with positioning requirements.
Because this specimen holder itself has illumination functions; The locating piece location and installation is on intermediate plate, and therefore, the operator does not need the right-hand man to cooperate; Needn't use electric torch in addition; Needn't use locating device in addition, both can reduce because the narrow and small danger that brings to the operator in testing machine space can reduce labor intensity again.
The utility model is compared with existing specimen holder, has handling safety, convenience, and the location is accurately high, the advantage of increasing work efficiency.

Fig. 3 is the locating piece structural representation.
Among the figure: 1-illuminating lamp, 2-spring, 3-intermediate plate, 4-locating piece
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Like Fig. 1, shown in 2, the utility model is made up of two intermediate plates 3 and spring 2, and two intermediate plate 3 upper end are fixedly connected; A spring 2 is placed at its two intermediate plate 3 middle parts; Wherein side intermediate plate bottom is equipped with rectangular parallelepiped locating piece 4, has the boss that matches with the impact specimen breach on the locating piece broadside, and an illuminating lamp 1 is set between the two intermediate plate tops; Illuminating lamp 1 can be as required, the adjustment brightness of illumination;
Have slideway on two intermediate plates of the utility model, spring end is installed in the slideway, and spring keeps intermediate plate to be in normally open; And can in the slideway of two intermediate plates 3, move, spring 2 keeps intermediate plate 3 to be in normally open, when using the utility model; Different test operation persons; According to individual's operating habit, can adjust the position of spring 2 on intermediate plate 3, make rapid operation, convenient; Because spring 2 is between two intermediate plates 3,, be convenient to the gripping sample so two intermediate plates 3 keep normally open; After the groove fit of boss on the rectangular parallelepiped locating piece 4 and impact specimen is good, sample is taken out from cryostat,, place locating piece 4 between two anvil blocks, easily sample is positioned on the anvil block with positioning requirements.
Because this specimen holder itself has illumination functions; Locating piece 4 location and installation are on intermediate plate 3, and therefore, the operator does not need the right-hand man to cooperate; Needn't use electric torch in addition; Needn't use locating device in addition, both can reduce because the narrow and small danger that brings to the operator in testing machine space can reduce labor intensity again.
