Description

A kind of can the falling ball impact test machine of accurate locking ball central point
Technical field
The present invention relates to a kind of proving installation of anti-impact force, particularly relate to a kind of can the falling ball impact test machine of accurate locking ball central point.
Background technology
Have the electronic installation of screen, such as the test such as notebook computer, panel computer, mobile communication terminal, LCD screen machine, needs the anti-impact force testing its body.
The central point of falling sphere is all aimed at the test point of measured object by range estimation by the test machine adopted in the market, owing to needing the size (namely steel ball quality changes) changing steel ball in test process, therefore there is following shortcoming:
Tested thing is positioned at below steel ball, steel ball holds by the electromagnet energizing magnetic power above it by steel ball, after the steel ball of various different-diameter held by the electromagnet of top, center can not ensure, often there is the situation of steel ball sideslip, when electromagnet once power-off, steel ball will do the movement of falling object, so will cause the poor placement of steel ball.
The invention provides a kind of mode of quick position steel ball central point, existing technical disadvantages can be improved, the drop point center of steel ball is ensured.
Summary of the invention
Goal of the invention: the object of the invention is to for the deficiencies in the prior art, provide a kind of can the falling ball impact test machine of accurate locking ball central point, it can locking ball central point and drop point quickly and accurately, improves the precision of testing efficiency and test.
Technical scheme: of the present invention a kind of can the falling ball impact test machine of accurate locking ball central point, comprise base, lifting guide pillar and electromagnet, described lifting guide pillar is arranged on base, described electromagnet is arranged on lifting guide pillar by connecting link, the lower surface of described electromagnet is provided with the spherical groove of absorption steel ball, this experimental machine also comprises an inverted cone tool, described inverted cone tool comprises the housing that can be sleeved on from bottom to top on electromagnet, described housing sidewall has the notch for holding described connecting link when being set with, the inverted cone that the lower surface being provided with steel ball in inwall and described groove in described housing fits, the center line of described inverted cone is overlapping with the center line of tubular shell.
In order to the drop point of further locking ball on body to be tested, the vertex of a cone hanging of described inverted cone has vertical.
Concrete test process is: when steel ball is held in a groove by electromagnet, described housing is sleeved on electromagnet from bottom to top, inner inverted cone wall is utilized to touch steel ball completely, the central point of steel ball can be made to be positioned at the tap web of circular cone, and then to determine the drop point of steel ball by the vertical that the circular cone vertex of a cone suspends in midair.
The present invention compared with prior art, its beneficial effect is: of the present invention can the falling ball impact test machine of accurate locking ball central point, structure is simple, convenient test, it can the central point of locking ball and drop point quickly and accurately, improves the precision of testing efficiency and test.
Accompanying drawing explanation
Fig. 1 is diagrammatic cross-section of the present invention.
Fig. 2 is the diagrammatic cross-section of described inverted cone tool.
Fig. 3 is the partial enlarged drawing that described inverted cone tool is sleeved on electromagnet.
Embodiment
Below technical solution of the present invention is described in detail, but protection scope of the present invention is not limited to described embodiment.
As shown in Figure 1, a kind of can the falling ball impact test machine of accurate locking ball central point, comprise base 1, lifting guide pillar 2, electromagnet 3, inverted cone tool and vertical 4, described lifting guide pillar 2 is arranged on base 1, described electromagnet 3 is arranged on lifting guide pillar 2 by connecting link 5, the lower surface of described electromagnet 3 is provided with the spherical groove 7 of absorption steel ball 6, described inverted cone tool comprises the tubular shell 8 that can be sleeved on from bottom to top on electromagnet, described tubular shell 8 sidewall has the notch 9 for holding described connecting link 5 when being set with, the inverted cone 10 that the lower surface being provided with steel ball 6 in inwall and described groove 7 in described tubular shell 8 fits, the center line of described inverted cone 10 is overlapping with the center line of tubular shell 8, the vertex of a cone hanging of described inverted cone 10 has described vertical 4.
When steel ball 6 is held in groove 7 by electromagnet 3, described tubular shell 8 is sleeved on electromagnet 3 from bottom to top, inner inverted cone 10 is utilized to touch steel ball 6 completely, the central point of steel ball 6 can be made to be positioned at the tap web of inverted cone 10, and then to determine the drop point of steel ball 6 by the vertical 4 that the vertex of a cone of inverted cone 10 suspends in midair.
Above-mentioned can the falling ball impact test machine of accurate locking ball central point, structure is simple, convenient test, and it can locking ball drop point quickly and accurately, improves the precision of testing efficiency and test.
As mentioned above, although represented with reference to specific preferred embodiment and described the present invention, it shall not be construed as the restriction to the present invention self.Under the spirit and scope of the present invention prerequisite not departing from claims definition, various change can be made in the form and details to it.
