Description
Technical field
The present invention relates to a kind of test unit, especially a kind ofly be used for that battery falls, the free fall test device of impact test.
Background technology
Mainly there are " setting of sample falling height " and " sample freely falls the realization of mode " two emphasis in the function design of drop machine.
For " setting of sample falling height ", can reduce " elevated height mode " and " hoisting depth setting " two problems again." elevated height mode " can be passed through such as realizations such as leading screw hoisting way, chain hoisting way; " hoisting depth setting " can be passed through realizations such as step motor control, limit switch control.These all are conventional mechanical drive and control, implement not have very big difficulty.
For " sample freely falls the realization of mode ", implementing just has great difficulty, and common implementation has following two kinds now:
First kind of mode is to realize that through panel turnover mechanism in this mechanism, sample is placed on the turnover panel, and turnover panel is driven by pneumatic or hydraulic piston cylinder.During test,, and then cause sample to lose support, fall from certain altitude through the motion driving turnover panel motion of piston cylinder.Be not difficult to find from principle analysis: lose turnover panel in the rotation of piston cylinder traction turnover panel up to sample and support the process that drops down, sample must rotate and lose original horizontal level along with the rotation of turnover panel.Because the rotation of turnover panel causes the sample end away from rotation axis at first to break away from turnover panel, and a gravitate and serve as spool to carry out circular motion with the contact point of sample and turnover panel.But because the rotation acceleration and the acceleration of gravity of turnover panel do not wait, sample is different with the speed of turnover panel, and sample and turnover panel break away from.Can know that from mechanics and kinematic principle analysis this moment, the dropping process of sample was not freely to fall, but two kinds of irregular falling that forms of motion is synthesized into of sample rotation of causing by the turning moment of freely falling with initial centripetal force form.In practice, this mechanism generally is used for the drop performance detection test of papery packing case.For reducing the influence of the problems referred to above, mostly take to increase the turnover panel rotation acceleration, reduce the turnover panel method of actuation time.
The second way is to realize that through two panel turnover mechanisms two turnover panel falling mechanisms are a kind of improved forms of single turnover panel falling mechanism.Under perfect condition, it can overcome the problems referred to above of single turnover panel falling mechanism, but must satisfy three conditions this moment simultaneously: one of which, and the center of gravity of sample must overlap with the center of sample; Its two, the center of sample must overlap with the centre junction zygonema of left and right sides turnover panel; Its three, rotatablely moving of left and right sides piston traction left and right sides turnover panel must be fully synchronously.If there is any one condition not satisfy, this mechanism all can produce the motion stack problem identical with single turnover panel falling mechanism.
In addition; Above-mentioned two kinds of turnover panel falling mechanisms also have a more scabrous problem; Now the shape of battery all is that requirement according to its employed equipment designs; The shell shape that be difficult to guarantee battery sample is regular, and at this moment, how the sample battery prevents on turnover panel and do not topple is exactly a hang-up.
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in the prior art, a kind of simple to operate, practical free fall test device is provided.
According to technical scheme provided by the invention; A kind of free fall test device; Column is set on pedestal, on the pedestal of column one side, is fixed with left supporting base and right supporting base, characteristic is: on said column, be pivoted with first cylinder; On right supporting base, be provided with second cylinder, on left supporting base, be provided with clamping plate; The piston rod of said first cylinder is connected with support plate, is connected with the push rod chuck on the piston rod of said second cylinder, and said clamping plate and push rod chuck are on a surface level.
One side and the column of said support plate are pivoted.
Said push rod chuck and clamping plate are arranged on the top of support plate.
Upper surface at said pedestal is provided with the Korean pine plank.
On said column, be provided with control panel.
The present invention is simple to operate, practical; Effectively realized freely falling of battery; Solved the problem that the turnover panel that brings because cell shapes is irregular topples.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the left view of Fig. 1.
Embodiment
Below in conjunction with concrete accompanying drawing the present invention is described further.
Like Fig. 1～shown in Figure 2: the free fall test device comprises pedestal 1, column 2, left supporting base 3, right supporting base 4, first cylinder 5, second cylinder 6, support plate 7, push rod chuck 8, clamping plate 9, control panel 10, Korean pine plank 11 etc.
The present invention is employed in column 2 is set on the pedestal 1; On the pedestal 1 of column 2 one sides, be fixed with left supporting base 3 and right supporting base 4, on column 2, be pivoted with first cylinder 5, on right supporting base 4, be provided with second cylinder 6; On left support plate 3, be provided with clamping plate 9; The piston rod of said first cylinder 5 is connected with support plate 7, is connected with push rod chuck 8 on the piston rod of said second cylinder 6, and said clamping plate 9 and push rod chuck 8 are on same surface level; One side and the column 2 of said support plate 7 are pivoted;
Said push rod chuck 8 and clamping plate 9 are arranged on the top of support plate 7;
Upper surface at said pedestal 1 is provided with Korean pine plank 11;
On column 2, be provided with control panel 10.
The course of work of the present invention: at first rise support plates 7, battery sample is placed on the support plate 7, battery sample is clamped between clamping plate 9 and the push rod chuck 8 by the push rod chuck 8 of second cylinder, 6 piston rod heads by first cylinder 5; By first cylinder 5 support plate 7 is rotated, battery sample breaks away from the surface of support plate 7 again, only by clamping plate 9 and 8 clampings of push rod chuck; Drive push rod chuck 8 by second cylinder 5 and leave battery sample, battery sample freely falls.The present invention is that support plate 7 is formed with the push rod chuck by panel turnover mechanism mainly; The main effect of support plate 7 no longer is the implementation of falling but only plays the benchmark effect into scalariform article falling height location that push rod chuck 8 is only the core institution of realizing that battery sample freely falls with clamping plate 9.
