In the field of servers and their packaging reliability, related term explanations are provided. Zero drop test platform: the test instrument is used for simulating the falling condition of various articles in the using and transporting processes. The jig comprises: the jig is a tool for carpenters, ironmen, pincers, machines, electrical controls and other handicrafts, and is mainly used as a tool for assisting in controlling position or action (or both). The jig can be divided into a process assembly type jig, a project test type jig and a circuit board test type jig.
The two existing drop test machine tools are designed, the turning plate type structure is simple, but the drop test of zero drop and lower height (less than about 200 mm) cannot be supported; the wedging type can support zero-drop, but the installation is difficult (generally needs to be buried underground), and the work needs to rely on an external air pump, and the deployment condition is higher.
In a first specific embodiment, the utility model provides a tool for a zero-drop test bench, which comprises a guide rail 2 and a sliding component 3, wherein the sliding component 3 is arranged on the guide rail 2; in the use and installation process of the jig for the zero-drop test bench, the guide rail 2 is installed on the test bench, the test bench drives the guide rail 2 to lift through the lifting component of the test bench, such as the lifting upright post 1, and then drives the whole jig for the zero-drop test bench to realize lifting motion.
The sliding assembly 3 is used for bearing the test product 4 before the drop test and separating the test product 4 during the drop test so that the test product 4 can fall naturally. In order to better bear the test article 4, the number of the sliding assemblies 3 is set as a pair, and the pair of sliding assemblies 3 are both connected with the guide rail 2 in a sliding manner; when bearing, the pair of sliding components 3 are fixed and do not slide, and are respectively supported on two sides of the bottom of the test product 4 so as to provide a stable supporting function; when falling, the pair of sliding assemblies 3 respectively slide towards opposite directions, that is to say, the pair of sliding assemblies 3 are separated from each other, until the sliding assemblies are drawn out from the bottom of the test article 4 and no longer provide bearing, and the test article 4 naturally falls.
The jig for the zero-drop test bench has the advantages of being simple in structure, convenient to install and low in cost, and meanwhile zero drop can be achieved.
It should be noted that, the present embodiment does not specifically limit the sliding installation structure of the guide rail 2 and the sliding assembly 3, that is, the sliding assembly 3 is installed on the guide rail 2 and has various structural forms for implementing sliding, the sliding manner includes but is not limited to gear transmission, slide rail transmission, and the like, and the driving manner includes but is not limited to electric driving, hydraulic driving, and the like, and the present embodiment also belongs to the description scope of the present embodiment.
Illustratively, the sliding assembly 3 and the guide rail 2 are in sliding connection in the form of electric drive and gear engagement.
In this embodiment, the slide assembly 3 carries the test items 4 in various ways.
For example, the slide assemblies 3 may be configured as rods, plates or any shape, and the pair of slide assemblies 3 may provide point contact supports or surface contact supports corresponding to different shapes at two locations on the bottom of the test object 4, respectively, so that the test object 4 may be simply placed on the pair of slide assemblies 3, and the slide assemblies 3 may limit only the degree of freedom in the height direction in which the test object 4 falls, and may not limit the degree of freedom in the plane perpendicular to the height direction.
Besides, the slide module 3 can restrict the degree of freedom of the test article 4 other than the height direction of the fall. Exemplarily, the inboard of a pair of sliding component 3 all is equipped with the location mesa, and a pair of location mesa is used for with 4 bottom edge's of test article vertical corner location laminating, and at this moment, sliding component 3 not only limits the direction of height's that test article 4 fell degree of freedom, still limits the degree of freedom in the plane perpendicular with the direction of height, has more firm fixed effect before falling test article 4, avoids receiving external interference before falling like collision and influences the drop test.
More specifically, the positioning table top comprises a bottom surface for limiting the degree of freedom in the height direction of falling and a side surface for limiting the degree of freedom in the plane direction perpendicular to the height direction, at the moment, the cross section of a single positioning table top is L-shaped, a pair of positioning table tops are symmetrical, and the cross section of a pair of positioning table tops is U-shaped after folding.
In a specific embodiment, the sliding assembly 3 is provided in a split manner, that is, the sliding assembly 3 includes two independent parts, and the two parts are assembled and fixed after being independently processed.
In this embodiment, the sliding assembly 3 includes a moving portion 31 and a mounting portion 32, the moving portion 31 is fixedly connected to the mounting portion 32, the moving portion 31 is slidably connected to the guide rail 2, and the positioning table is located on the mounting portion 32.
Wherein, the moving part 31 includes a motor and a moving gear 311 driven by the motor to rotate, the guide rail 2 includes a gear track 211, the sliding component 3 is engaged with the gear track 211 through the moving gear 311 and then slidably connected with the guide rail 2, and the sliding component 3 slides on the guide rail 2 through the rotation of the motor.
In a specific embodiment, the guide rail 2 is arranged along the horizontal direction, the pair of sliding assemblies 3 are arranged along the horizontal direction, a distance is left between the pair of sliding assemblies 3 and is adjustable, and when the test device is used, the pair of sliding assemblies 3 on the guide rail 2 are adjusted to be a proper distance according to the size of a test article 4, so that the test article 4 is placed on the pair of sliding assemblies 3 and does not fall off.
In addition, the mounting portion 32 is disposed in a vertical direction, and in a popular way, the mounting portion 32 extends outward and supports the test piece 4; in embodiments of the positioning table that provide multiple degree of freedom constraints, the positioning table extends and is arranged in a vertical direction, co-directional with the mounting portion 32.
The utility model also provides a zero drop test platform, including lift stand 1 and the above-mentioned tool that is used for zero drop test platform, guide rail 2 is installed in lift stand 1, by lift stand 1 through drive guide rail 2 go up and down and then realize being used for the elevating movement of the tool of zero drop test platform.
The zero-drop test bench has all the beneficial effects of the jig for the zero-drop test bench, and the zero-drop test bench is not repeated.
Compared with a zero-drop test bench adopting a turning plate type and wedged type jig, the zero-drop test bench adopts the jig for the zero-drop test bench, can support drop tests with lower height (below 200 mm), does not need buried installation and an external air pump, and has the characteristic of convenience in installation.
