Problems solved by technology

[0004] The technical problem to be solved by the present invention is: in order to solve the existing stacking test evaluation test results, there is a large deviation, especially when the center of gravity of the stacking is close to the edge or the stacking height is high, the deviation is larger, and the test results are not accurate. Accurate, which brings a lot of inconvenience to parameter measurement, qualitative and quantitative evaluation of whether the protection design of item packaging is reasonable, etc.

Embodiment 1

[0035] Such as Figure 1 to Figure 4 As shown, the present invention discloses a storage stacking test tool, including: a reference unit arranged beside the stacking, a follower unit arranged above the reference unit and capable of reflecting the displacement of the topmost items in the stacking, the The offset generated by the follower unit relative to the reference unit is used to reflect the offset and offset direction of the stacking relative to the initial storage state. By setting the follow-up unit to simulate the displacement of the top-level items in the stack, and then measuring the offset generated by the follow-up unit relative to the reference unit after storage, the horizontal offset and height drop generated by the stack during storage can be obtained. Combining with parameters such as the height of stacking, the deflection angle of stacking is further obtained. The follow-up unit simulates the displacement of the top stacked items, and the obtained parameters ...

Embodiment 2

[0040] This embodiment is basically the same as the first embodiment, the only difference is that a fixed plate 4 is connected between the several adjusting rods 3 , and the fixed plate 4 and the horizontal plate 2 are respectively welded to the several adjusting rods 3 . That is, the welding connection is used to replace the clamping and fixing of the bolts 6 and gaskets 7 in the first embodiment. This structure is more stable, and there is no need to worry about the displacement of the horizontal plate 2 during the test, but its adjustability is too poor. The height cannot be adjusted, and it can only be used for stacking tests within a certain height range.

Embodiment 3

[0042] This embodiment is basically the same as the first embodiment, the only difference is that, on the basis of the horizontal plate 2 , the reference unit further includes a hydraulic device with a scale for adjusting the height of the horizontal plate 2 . That is, the height of the horizontal plate 2 from the ground is accurately determined by adjusting the degree of expansion and contraction of the hydraulic device in combination with the scale; the operation is simple and the data is accurate.

Abstract

The invention belongs to the technical field of test tools, and discloses a storage stack test tool and a test method thereof. The test tool comprises a reference unit arranged beside a stack, and a servo unit arranged above the reference unit and reflecting the displacement of an article at the uppermost layer of the stack. The servo unit simulates the displacement of the article at the uppermost layer of the stack, the offset amount of the servo unit relative to the reference unit after storage ends is measured to obtain the horizontal offset amount and the height decrease amount generated in the storage process of the stack, and the height of the stack is combined to further obtain the deflection angle of the stack, so further improvement of packaging design of articles is facilitated. The storage stack test method has the advantages of simple structure of a test device, low cost, small influences on the stack, simple operation of the test process, and high accuracy and authenticity of obtained parameters, is of great reference significance to assess whether the packaging protection design of the articles is reasonable or not, and makes the design scheme be conveniently and timely adjusted.

Description

technical field [0001] The invention relates to the technical field of testing tooling, in particular to a storage stacking testing tooling and a testing method. Background technique [0002] The stacking test evaluation will play a very important role in the design stage of the packaging. In the existing stacking test of items, the test stacking is often pressurized by approximately uniform force, and then stacked with the physical objects in the warehouse. In comparison, the result has a large deviation, and the deviation will be more obvious when the center of gravity of the item is closer to the edge; and the physical stacking height in the warehouse is usually relatively high, some will reach 3 meters or even higher. After stacking, not only There are changes in height and inclination, and the deviation of measurement results is relatively large, which brings a lot of inconvenience to parameter measurement and qualitative and quantitative evaluation of whether the prote...
