Description

A kind of novel high-low temperature chamber testing machine

Technical field:

The utility model relates to high-low temperature chamber testing machine technical field, refers in particular to a kind of novel high-low temperature chamber testing machine.

Background technology:

Various materials all can present different temperature characterisitics under different temperature, the characteristic that object is showed under different temperatures has then often determined its whether suitable being used in some field and the occasion, the temperature characterisitic of normally testing some objects with the high-low temperature chamber testing machine at present, traditional high-low temperature chamber generally partly is made up of casing, well heater, cooling system and temperature control equipment etc.Present high-low temperature chamber testing machine generally is placed on the punctuate extensometer outside the case, and it is high or can not be with the very intuitive and accurate shortcoming such as show of test result to make the punctuate extensometer exist measuring accuracy when test test specimen displacement.This all selects the more suitable material of a kind of temperature characterisitic to bring certain adverse effect to people, so present people wish to have emerging of a kind of a kind of high-low temperature chamber testing machine that can overcome these shortcomings.

The utility model content:

The purpose of this utility model is, at above problem, by improving existing technology, provides a kind of novel high-low temperature chamber testing machine.

For achieving the above object, the utility model adopts following technical scheme: it mainly comprises: a casing, in casing, be provided with the punctuate extensometer, and the punctuate extensometer links to each other by the outer upper and lower bearing of its upper and lower axle and casing.

Upper and lower bearing recited above is connected on the slide rail by slide block.

Described in the above upper and lower axle is provided with a heating apparatus of being made up of temperature switch and heating tube with the inside and outside junction of casing.

The beneficial effects of the utility model are: adopted and be provided with the punctuate extensometer in casing, a kind of high-low temperature chamber that upper and lower bearing is connected on the slide rail by slide block and the junction is provided with a heating apparatus of being made up of temperature switch and heating tube inside and outside upper and lower axle and casing simultaneously with brand new, not only improved measuring accuracy greatly, can also be more accurately, show intuitively with test result.

Description of drawings:

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is one of structural representation of the present utility model (part is cut open).

Fig. 2 is the partial enlarged drawing of accompanying drawing 1.

Fig. 3 is the side view of Fig. 1.

Fig. 4 is upper and lower axle, upper and lower bearing, heating apparatus, slide rail syndeton synoptic diagram.

Embodiment:

See accompanying drawing 1, the utility model mainly comprises: a casing 1, in casing 1, be provided with punctuate extensometer 2, and punctuate extensometer 2 links to each other with casing 1 upper and lower bearing 23 outward by upper and lower grip slipper 21, upper and lower axle 22.

Upper and lower bearing 23 recited above is connected on the slide rail 25 by slide block 24.

Described in the above upper and lower axle 22 is provided with a heating apparatus 3 of being made up of temperature switch 31 and heating tube 32 with casing 1 inside and outside junction.

Punctuate extensometer 2 is a kind of in the displacement transducer, the main effect of described punctuate extensometer 2 is to measure move distance in the utility model, it mainly is made up of upper and lower grip slipper 21, upper and lower axle 22, upper and lower bearing 23, slide block 24, slide rail 25, code translator 26 and counterweight counterweight 27, the major function of code translator 26 is that mechanical motion is converted to the electric signal that can transmit, and the weight of the counterweight counterweight 27 upper and lower grip slipper 21 that is balances, upper and lower axle 22, upper and lower bearing 23 and slide block 24.On the basis of existing technology punctuate extensometer 2 is arranged on the temperature characterisitic that can test out measured object among the high-low temperature chamber testing machine more accurately, also can test structure be showed simultaneously more accurate and visually.

Punctuate extensometer 2 is inserted in the high-low temperature chamber body 1, uses, lower shaft 22 and casing 1 outer upper and lower bearing 23 is connected, and is connected by smooth with slide block between upper and lower bearing 23 and the slide rail 25.So just can guarantee that punctuate extensometer 2 moves in one direction, can not influence precision because of producing component.Be in casing 1 inside and outside intersection at last lower shaft 22 heating apparatus 3 of being made up of temperature switch 31 and heat-generating pipe 32 is set, when being low temperature in the casing 1, heating apparatus 3 is dissolved herein because of the generation frost of the temperature difference, prevents to increase because of frost the precision of upper and lower axle 22 and the friction force influence test of casing 1.When being high temperature in the casing 1, heating apparatus 3 is consistent the upper and lower axle 22 and the temperature of casing 1 periphery, avoids upper and lower axle 22 to expand and friction force that casing 1 does not expand and produces, keeps accurate measuring accuracy.

The stability of the equipment during use high-quality high-low temperature resistant material guarantees to test in the selection of this machine, utilize high precision line slide rail and straight line slide bar to guarantee the smart quick measurement of test piece deformation in the test on the structure, utilizing warm and humid balancing method to guarantee to test on the method and not being subjected to drip to reveal influences.

Certainly, the embodiment of the above, it is preferred embodiments of the present utility model, be not to limit the utility model practical range, so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and all should be included in the utility model claim.
