Drop test machine capable of simulating continuous drop

Abstract

The invention discloses a drop test machine capable of simulating continuous drop. The invention belongs to the technical field of testing. The drop test machine comprises an objective table, a clamping mechanism, a driving mechanism, a supporting rod group and an eccentric wheel group. The driving mechanism is in transmission connection with the supporting rod group through the eccentric wheel group, and the supporting rod group abuts against the objective table. When a to-be-tested sample machine falls to the objective table from the clamping mechanism, the supporting rod group can drive theobjective table to do instantaneous descending motion to realize continuous drop test. The clamping mechanism comprises a first clamping group, a second clamping group and a horizontal feeding mechanism, and the horizontal feeding mechanism can drive the second clamping group to do reciprocating feeding motion to be matched with the first clamping group to clamp or loosen the to-be-tested samplemachine. According to the drop test machine capable of simulating continuous drop disclosed by the invention, the clamping mechanism is matched with the objective table capable of instantaneously dropping to simulate a continuous drop state, so that the test indexes are more abundant and diverse, the test height does not need to be adjusted by manually clamping for multiple times, and the operation is more convenient and quicker.

Description

technical field [0001] The invention relates to the technical field of testing, in particular to a drop testing machine capable of simulating continuous drop. Background technique [0002] All kinds of electronic products may be damaged due to accidents during use. Therefore, major brand manufacturers and component manufacturers around the world have increased product drop tests. Most of the damage to electronic products comes from drop collisions. R&D personnel often spend a lot of time and cost on product-related quality tests. The most common structural tests are drop and impact tests. [0003] Chinese patent document publication number CN208847444U discloses a kind of drop test equipment for electronic products, including a frame, a motor, a transmission assembly, a supporting shaft, a special-shaped wheel, a follower wheel, a push rod, a drop test plate and a side enclosure; There is a side enclosure, the drop test plate is located inside the side enclosure; the ejecto...

Problems solved by technology

[0004] However, the drop test height of the above-mentioned electronic product drop test equipment is single, and it is difficult to meet the detection requirements of the product under test for multiple heights. Moreover, when the user uses the electronic product to drop, it is usually the same electronic product that has different heights. Drop, the above-mentioned electronic product drop test equipment is difficult to simulate the drop situation, and the drop detection results are relatively simple
