Problems solved by technology

If any one of the conditions is not met, the mechanism will have the same motion superposition problem as the single-flap drop mechanism
[0007] In addition, there is another problem that is difficult to solve for the above two flipping plate drop mechanisms. Now the shape of the battery is designed according to the requirements of the equipment used. It is difficult to ensure that the shape of the shell of the battery sample is regular. At this time, how to prevent the sample battery from overturning on the flip plate is a big problem

Abstract

The invention relates to a free drop test device. A vertical column is arranged on a base, and a left supporting seat and a right supporting seat are fixed on the base at one side of the vertical column. The free drop test device is characterized in that a first air cylinder is pivoted on the vertical column, a second air cylinder is arranged on the right supporting seat, and a splint is arranged on the left supporting seat; a piston rod of the first air cylinder is connected with a supporting plate, a piston rod of the second air cylinder is connected with a handspike clamp which is arranged on the plane together with the splint, one side of the supporting plate is pivoted on the vertical column, the handspike clamp and the splint are arranged at the upper part of the supporting plate, the upper surface of the base is provided with a pine wood board, and the vertical column is provided with a control panel. The invention is easy to operate and practical, effectively realizes the free drop of batteries and solves the problem of plate turnover because of irregular battery shapes.

Description

technical field [0001] The invention relates to a test device, in particular to a free drop test device for battery drop and impact tests. Background technique [0002] The functional design of the drop tester mainly has two key points: "setting of the drop height of the sample" and "realization of the free drop method of the sample". [0003] For the "setting of the drop height of the sample", it can be summarized into two issues of "height raising method" and "lifting height setting". The "height lifting method" can be realized by such as screw lifting method, chain lifting method, etc.; the "lifting height setting" can be realized by stepping motor control, limit switch control, etc. These are conventional mechanical transmission and control, and there is no great difficulty in realizing them. [0004] For the "realization of the sample free fall method", it is very difficult to realize, and now there are two common implementation methods: [0005] The first is achieve...
