Description

Highly Accelerated Life Test case calibration clamp

Technical field:

The utility model relates to HAST calibration clamp technical field more particularly to a kind of Highly Accelerated Life Test case calibration folders Tool.

Background technique:

When calibrating Highly Accelerated Life Test case, it is necessary to two temperature sensors, the two sets of special fixtures provided using producer With a drinking cup special, not only expense needs a Wan Duoyuan (6000 yuan of temperature sensor every, fixture and cup through calculating in this way Totally 500 yuan), and be not suitable for our current temperature testing equipments.Conventional enterprise or laboratory purchase similar high temperature, high pressure, When high humidity equipment, typically import, when calibration is also the general temperature transducer provided using manufacturer and matched clamp etc., because To can't buy similar temperature measuring equipment in the market, therefore buying expenses are also very expensive, sometimes matched with enterprise or laboratory Measuring device mismatches.

Utility model content:

Utility model aims to solve defect in the prior art, provide that a kind of structure is simple, convenient for mounting and clamping, system Make lower-cost Highly Accelerated Life Test case calibration clamp.

The utility model is achieved by the following technical solution: a kind of Highly Accelerated Life Test case calibration clamp, including The chuck body for being arranged in chamber and being fixedly connected with temperature probe, the chuck body include and the fixed company of temperature probe The collets that connect and the sample holder for being fixed on collets bottom end, the sample holder are hollow structure, top tool There is opening, there are several sample card slots in sample holder, the temperature probe end passes through the collets and is correspondingly arranged In sample holder overthe openings.

For the ease of grafting sample, the sample card slot is rectangle, and top has trapezoidal targeting port.

Sample slides in mosaic process in order to prevent, and the sample card slot inner wall has anti-slop serrations.

For the ease of the installing and dismounting of collets, sample holder top is integrally formed with U-shaped inserted block, the insulation Block is removably attached in U-shaped inserted block.

The beneficial effects of the utility model are: the Highly Accelerated Life Test case calibration clamp structure is simple, easy to assembly, system Cost is relatively low for work, can effectively cooperate with temperature probe, and sample is effectively fixed, to accurately measure more than one piece sample Service life, it is very easy to use.

Detailed description of the invention:

Fig. 1 is that the Highly Accelerated Life Test case calibration clamp of the utility model is mounted on the structural schematic diagram in chamber；

Fig. 2 is the side view of the Highly Accelerated Life Test case calibration clamp of the utility model；

Fig. 3 is the top view of the Highly Accelerated Life Test case calibration clamp of the utility model；

Fig. 4 is the schematic diagram of internal structure of the Highly Accelerated Life Test case calibration clamp of the utility model；

In figure: 1. chambers, 2. locking devices, 3. temperature probes, 4. chuck bodies, 41. collets, 42. samples are placed Box, 43.U type inserted block, 44. locating pieces, 45. sample card slots, 46. trapezoidal targeting ports, 47. anti-slop serrations.

Specific embodiment:

The preferred embodiment of the utility model is described in detail with reference to the accompanying drawing, so that the advantages of the utility model It can be easier to be understood by those skilled in the art with feature, to make apparent specific boundary to the protection scope of the utility model It is fixed.Direction term that the utility model is previously mentioned, such as "upper", "lower", "front", "rear", "left", "right", "top", "bottom" etc., It is only the direction with reference to annexed drawings.Therefore, the direction term used be to illustrate and understand the utility model, rather than to Limit the utility model.

As shown in Figure 1, a kind of Highly Accelerated Life Test case calibration clamp, including be arranged in chamber 1 and visited with thermometric First 3 chuck bodies 4 being fixedly connected, wherein temperature probe 3 is fixed on pipeline by locking device 2, and test is protruded into end In case 1, and chuck body 4 is lifted on 3 end of temperature probe.

As in Figure 2-4, the chuck body 4 includes the rectangular dielectric block 41 being fixedly connected with temperature probe 3 and consolidates It is scheduled on the rectangle sample holder 42 of 41 bottom end of collets, the sample holder 42 is hollow structure, and top has opening, There are several sample card slots 45,42 top of sample holder is integrally formed with U-shaped inserted block 43, the insulation in sample holder 42 Block 41 is removably attached in U-shaped inserted block 43 by screw, and 3 end of temperature probe passes through the collets 41 and corresponds to It is arranged in 42 overthe openings of sample holder.

As shown in figure 4, having multiple locating pieces 44 in sample holder 42, sample card slot is formed between each locating piece 44 45,45 bottom end of sample card slot is rectangle, and top has trapezoidal targeting port 46, and the sample card slot inner wall has anti-slop serrations 47。

The fixture of the utility model, there is 5 sample card slots 45 in fixture, each 45 inner wall of sample card slot perpendicular to bottom surface, Can guarantee in this way can be both perpendicular to bottom surface after sample is put into sample card slot 45, and the sample after guaranteeing grinding is flat in same analysis Face.Each 45 inner wall of sample card slot uses tooth Shape Design in fixture, can increase the frictional force that inner wall is contacted with sample in this way, prevents Sample slides in mosaic process.Each 45 top of sample card slot uses V-type or trapezoidal design in fixture, sample can be made from side Face can be easily pushed into fixture when installing.

Compared with prior art, the Highly Accelerated Life Test case calibration clamp structure is simple, easy to assembly, cost of manufacture compared with It is low, can effectively it cooperate with temperature probe, and sample is effectively fixed, to accurately measure the use longevity of more than one piece sample Life, it is very easy to use.

Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed, But it cannot be understood as the limitations to utility model patent range.It should be pointed out that for the common skill of this field For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to The protection scope of the utility model.
