A kind of falling ball impact test machine
Technical field
The present invention relates to a kind of proving installation of anti-impact force, relate in particular to a kind of falling ball impact test machine.
Background technology
Electronic equipment with screen, for example the finished product to be detected of completion is processed or made up to machines such as notebook computer, panel computer, mobile communication terminal, LCD screen, needs the anti-impact force of its body of test.
Relative height formula between the lifting guide pillar of the steel ball magnet base of test machine and fixing its height is adjustable in the market, and the location of magnet base height is to rely on the scale of carving on the lifting guide pillar to confirm height, and there is following shortcoming in this mode:
After the steel ball of different-diameter was held by the magnet base of its top, because diameter is different, what scale magnet base need be adjusted on, all need do a little additive operations, and the operator uses and will compare inconvenience.
The present invention provides a kind of quick measuring mode, can improve existing technical disadvantages, makes the drop point height of steel ball come into plain view.
Summary of the invention
Goal of the invention: the objective of the invention is to the deficiency to prior art, a kind of falling ball impact test machine is provided, it can measure the drop point height of different-diameter steel ball fast, improves the precision of testing efficiency and test.
Technical scheme: a kind of falling ball impact test machine of the present invention; Comprise base, lifting guide pillar and magnet base; Said lifting guide pillar is fixed on the base, and said magnet base is arranged on the lifting guide pillar through first clamp assembly, between said magnet base and the base apart from scalable; It is characterized in that; Also comprise laser range finder; Said laser range finder is between base and magnet base; Said laser range finder is arranged on the lifting guide pillar through second clamp assembly, and said laser range finder can horizontally rotate along lifting guide pillar, between said laser range finder and lifting guide pillar and the base apart from scalable.
Further improve technique scheme; Said second clamp assembly comprises the first cast cover, contiguous block and grip block, and the said first cast cover is sleeved on the lifting guide pillar, through the distance of slidable adjustment itself and base; One end of said contiguous block is fixed on the sidewall of first cast cover; The other end of said contiguous block has chute, and an end of said grip block can be fixed in the said chute horizontally slidingly, and its other end clamping has said laser range finder.
Test for ease, said magnet base can horizontally rotate along lifting guide pillar.
Further; Said first clamp assembly comprises second retaining sleeve and connecting link, and said second retaining sleeve is sleeved on the lifting guide pillar, through the distance of slidable adjustment itself and base; One end of said connecting link is fixed on the sidewall of second cast cover, and its other end is fixed with magnet base.
Concrete method of testing is: after steel ball is held by magnet base, the upper surface of laser range finder is contacted with steel ball, open laser range finder this moment; Stadimeter can be beaten beam of laser by measured object downwards; Detect the height value of the upper surface of stadimeter, and be presented on its liquid crystal screen, move the anchor clamps of magnet base and laser range finder then together apart from measured object; When being shown to the drop point height of test needs on the laser range finder screen; Magnet base and lifting guide pillar are fixed, and stadimeter can be turned to other not to be influenced on the steel ball drop test position, so gets final product.
The present invention compared with prior art, its beneficial effect is: falling ball impact test machine of the present invention, simple in structure, easy to use, can measure the drop point height of different-diameter steel ball fast, improve the precision of testing efficiency and test.

Embodiment
Be elaborated in the face of technical scheme of the present invention down, but protection scope of the present invention is not limited to said embodiment.
As illustrated in fig. 1 and 2; A kind of falling ball impact test machine; Comprise base 1, lifting guide pillar 2, magnet base 3 and laser range finder 4, said lifting guide pillar 2 is fixed on the base 1, and said magnet base 3 is arranged on the lifting guide pillar 2 through first clamp assembly; Said magnet base 3 can horizontally rotate along lifting guide pillar 1, between said magnet base 3 and the base 1 apart from scalable; Said laser range finder 4 is between base 1 and magnet base 3; Said laser range finder 4 is arranged on the lifting guide pillar 2 through second clamp assembly; Said laser range finder 4 can horizontally rotate along lifting guide pillar 2, between said laser range finder 4 and lifting guide pillar 2 and the base 1 apart from scalable.
Said second clamp assembly comprises first cast cover 5, contiguous block 6 and grip block 7; Said first cast cover 5 is sleeved on the lifting guide pillar 2; Through the distance of slidable adjustment itself and base 1, an end of said contiguous block 6 is fixed on the sidewall of first cast cover 5, and the other end of said contiguous block 5 has chute; But being fixed in the said chute of an end horizontal slip of said grip block 7, its other end clamping has said laser range finder 4.
Said first clamp assembly comprises second retaining sleeve 8 and connecting link 9; Said second retaining sleeve 8 is sleeved on the lifting guide pillar 2; Through the distance of slidable adjustment itself and base 1, an end of said connecting link 9 is fixed on the sidewall of second cast cover 8, and its other end is fixed with magnet base 3.
During test, steel ball makes the upper surface of laser range finder 4 contact with steel ball after being held by magnet base 3; Open laser range finder 4 this moment, laser range finder 4 meetings 10 dozens of beam of laser of measured object downwards detect the height value of the upper surface of laser range finder 4 apart from measured object 10; And be presented on its liquid crystal screen; Move the anchor clamps of magnet base 3 and laser range finder 4 then together, when being shown to the drop point height of test needs on laser range finder 4 screens, magnet base 3 and lifting guide pillar 2 are fixed; Laser range finder 4 can be turned to other not to be influenced on the steel ball drop test position, so gets final product.
As stated, although represented and explained the present invention that with reference to specific preferred embodiment it shall not be construed as the restriction to the present invention self.Under the spirit and scope of the present invention prerequisite that does not break away from the accompanying claims definition, can make various variations in form with on the details to it.
