Abstract
The utility model discloses fall test table, which comprises an upright post, a base, a bearing platform, a lifting assembly which is positioned above the bearing platform and is connected with the upright post, and a control assembly. The utility model is characterized in that the lifting assembly is a pneumatic finger, or a vacuum cup, or the combination of the pneumatic finger and the vacuum cup. The upright post is provided with a lifting guide rail. The connection between the lifting assembly and the upright post is the sliding connection between the lifting assembly and the lifting guide rail. After the pneumatic finger and the vacuum cup of a piece which is to be tested is driven, or clamped, or sucked to a set height, the pneumatic finger and the vacuum cup are controlled to instantly release the piece which is to be a tested to fall freely, and then, the break resistant performance and the impact resistant degree of the piece which is to be tested are tested. The utility model has the advantages that the speed of the test is fast, the stability of the piece which is to be tested in space is especially good, the height of the fall is consistent every time, the fall of ribs, surfaces and angles can be realized, the labor intensity of a test person is low, the test person is not easy to fatigue, the test results are fundamentally free from the affection of human factors, the artificial error rate is low, and the accuracy of the test is high.
Description
Technical field
The utility model relates to the device with the strength characteristics of the mechanical impact force test solid material that is only produced by the weight of free-falling, especially relates to a kind of falling test stand.
Background technology
Drop test be repeatedly with the structure member of certain product or its overall package finished product from the predetermined altitude free falling, and the structure member after at every turn falling or its overall package finished product tested, even guarantee product transport or carry in the process unexpected born, but still normal operation.The fall-down test of mobile phone generally is by 6 kinds of different angles from 1.5m and two kinds of setting heights of 0.30m, comprising liquid crystal display directly downwards free falling to hard cement flooring, if experience fall for 5 times after, but all impunity old place work of this mobile phone, the standard that its quality is just up to specification.Yet existing fall-down test generally is to draw scale at metope, and hand-held test specimen is to the height of setting, and loosing one's grip allows it freely fall, and testing its crash resistance then can be impact-resistant degree.Because test specimen is at the poor stability in space, testing crew is tired easily again, therefore, test result is subjected to human factor to influence the bigger error of existence, also have and adopt turnover plate type or convertible falling test stand, the former test period is longer, and the latter whenever does a kind of differing heights test, all needs to change the casing of implementing upset usefulness.
Summary of the invention
Technical problem to be solved in the utility model is the defective that remedies prior art, proposes the falling test stand that a kind of test speed is fast, efficient is high, test result is not influenced by human factor substantially.
Technical matters of the present utility model is solved like this:
This falling test stand, comprise column, fixing described column pedestal, be placed on bear on the described pedestal that test specimen carries out freely falling bear platform, be positioned at the described elevate a turnable ladder test specimen that bears the platform top and be connected and carry out the lifting component that freely falls and Control Component with described column.
The characteristics of this falling test stand are:
Described lifting component is pneumatic-finger, vacuum cup or their combination.Pneumatic-finger will be changed into the holding action of mechanical finger by the straight reciprocating motion of the piston of air pressure control, with clamping or discharge the test specimen of suitable clamping.Press the residing state of mechanical finger, pneumatic-finger can be divided into gathering formula, opening type and run-in index.Vacuum cup is controlled by vacuum generator, with the test specimen of sticking or the suitable sticking of release.
Described column is provided with lifting guideway, and described lifting component and being connected of described column are and being slidingly connected of described lifting guideway.Can adjust lifting component and the vertical range of bearing platform so easily, adapt to of the different requirements of the fall-down test of test specimen setting height.
Technical matters of the present utility model can further be solved like this:
The described platform that bears is steel platform, vulcanie platform, or the ground simulation platform.The fall-down test that can adapt to test specimen like this is to falling the different requirements in place.
Described lifting component is driven by the transmission of wire rope pulley lifting assembly in the slip of described column, described wire rope pulley lifting assembly comprises that an end is fixed on wire rope on the lifting component, is arranged on the fixed pulley on described column top, and is arranged on the described pedestal the fixedly reel of the wire rope other end.
The reel of described wire rope pulley lifting assembly is perhaps driven by hand turning handle by the elevate a turnable ladder direct motor drive.
Described Control Component comprises pneumatic-finger gauge tap, vacuum cup gauge tap and elevate a turnable ladder electric electromechanics source switch.
Described Control Component can be fixed on column or the pedestal, also can be arranged in the independent control enclosure of externally positioned type.
The utility model passes through by the elevate a turnable ladder direct motor drive, perhaps drive the pneumatic-finger, vacuum cup of clamping or sticking test specimen to the height of setting by handle drives wire rope pulley lifting assembly, control pneumatic-finger again, vacuum cup abrupt release test specimen freely falls, testing its crash resistance then can be impact-resistant degree.Has the advantage that detection speed is fast, efficient is high, especially test specimen is at the good stability in space, guarantee each falling height unanimity, and can realize that rib, face, angle fall, testing crew labour intensity is low, is not easy fatigue, and test result is not influenced by human factor substantially, probability of human error is low, test accuracy height.
Description of drawings
Below the contrast accompanying drawing and in conjunction with embodiment the utility model is described in further detail.
Fig. 1 is the composition structural representation of the utility model embodiment.
Fig. 2 is the side view of Fig. 1.
