Abstract
Disclosed in the utility model is a falling ball testing machine capable of accurately localizing a central point of a steel ball. The falling ball testing machine comprises a pedestal, a lifting guide rod and an electromagnet; the lifting guide rod is arranged on the pedestal; the electromagnet is arranged on the lifting guide rod by a connecting rod; and a spherical groove for absorbing a steel ball is arranged at the lower surface of the electromagnet. Besides, the testing machine also includes a turbination-shaped jig including a housing that is sleeved on the electromagnet from bottom to up; a notch for accommodating the connecting rod when the sleeving is carried out is arranged at the side wall of the housing; an turbination-shaped body is arranged inside the housing, wherein the inner wall of the turbination-shaped body is pressed tightly against the lower surface of the steel ball inside the groove; and the central line of the turbination-shaped body is superposed with the central line of the tubular housing. According to the utility model, falling ball testing machine has advantages of simple structure and convenient testing; the drop point of the steel ball can be localized rapidly and accurately; and the test efficiency and the test accuracy can be improved.
Description
Technical field
The utility model relates to a kind of proving installation of anti-impact force, relates in particular to a kind of falling ball impact test machine of accurately locking ball central point.
Background technology
Electronic installation with screen is tested machine such as notebook computer, panel computer, mobile communication terminal, LCD screen etc., needs the anti-impact force of its body of test.
The test machine that adopts is in the market all aimed at the central point of falling sphere by range estimation with the test point of measured object, owing to need to change the size (being that steel ball quality changes) of steel ball in the test process, so there is following shortcoming:
Tested thing is positioned at the steel ball below, steel ball holds steel ball by the electromagnet energising generation magnetive attraction of its top, because after the steel ball of various different-diameters is held by the electromagnet of top, the center can not guarantee, tend to occur the situation of steel ball sideslip, when in a single day outage of electromagnet, steel ball will be done the movement of falling object, so will cause the poor placement of steel ball.
The utility model provides a kind of mode of quick locking ball central point, can improve existing technical disadvantages, so that the drop point center of steel ball is guaranteed.
The utility model content
The utility model purpose: the purpose of this utility model is for the deficiencies in the prior art, a kind of falling ball impact test machine of accurately locking ball central point is provided, it is locking ball central point and drop point quickly and accurately, improves the precision of testing efficiency and test.
Technical scheme: the falling ball impact test machine of a kind of accurately locking ball central point described in the utility model, comprise base, lifting guide pillar and electromagnet, described lifting guide pillar is arranged on the base, described electromagnet is arranged on the 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 the electromagnet, have on the described housing sidewall for the notch that when being set with, holds described connecting link, be provided with the inverted cone that the lower surface of steel ball fits in inwall and the described groove in the described housing, the center line of described inverted cone and the center line of tubular shell are overlapping.
For the further drop point of 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 groove by electromagnet, described housing is sleeved on the electromagnet from bottom to top, utilize inner inverted cone wall to touch steel ball fully, can make the central point of steel ball be positioned at the tap web of circular cone, and then determine the drop point of steel ball by the vertical of circular cone vertex of a cone suspention.
The utility model compared with prior art, its beneficial effect is: the falling ball impact test machine of accurately locking ball central point described in the utility model, and simple in structure, convenient test, it is central point and the drop point of locking ball quickly and accurately, improves the precision of testing efficiency and test.
Description of drawings
Fig. 1 is diagrammatic cross-section of the present utility model.
Fig. 2 is the diagrammatic cross-section of described inverted cone tool.
Fig. 3 is that described inverted cone tool is sleeved on the partial enlarged drawing on the electromagnet.
Embodiment
The below is elaborated to technical solutions of the utility model, but protection domain of the present utility model is not limited to described embodiment.
As shown in Figure 1, a kind of falling ball impact test machine of accurately 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 the base 1, described electromagnet 3 is arranged on the 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 the electromagnet, have on described tubular shell 8 sidewalls for the notch 9 that when being set with, holds described connecting link 5, be provided with the inverted cone 10 that the lower surface of inwall and described groove 7 interior steel balls 6 fits in the described tubular shell 8, the center line of the center line of described inverted cone 10 and tubular shell 8 is overlapping, and 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 the electromagnet 3 from bottom to top, utilize inner inverted cone 10 to touch steel ball 6 fully, can make the central point of steel ball 6 be positioned at the tap web of inverted cone 10, and then the vertical 4 of the vertex of a cone suspention by inverted cone 10 is determined the drop point of steel ball 6.
The falling ball impact test machine of above-mentioned accurately locking ball central point, simple in structure, convenient test, it is the locking ball drop point quickly and accurately, improves the precision of testing efficiency and test.
As mentioned above, although the specific preferred embodiment of reference has represented and has explained the utility model that it shall not be construed as the restriction to the utility model self.Under the spirit and scope prerequisite of the present utility model that does not break away from the claims definition, can make in the form and details various variations to it.
