AI Technical Summary

Technical Problem

The existing aluminum alloy sheet crack resistance detection device is large in size and requires a long expansion and contraction length to be reserved. The force after impact will be transmitted to the fixed seat, resulting in slight damage to the fixed seat. Over time, it will cause the fixed seat to need to be replaced and the maintenance cost is high.

Method used

A crack-resistant performance detection device for aluminum alloy sheets is designed, adopting a shell structure, equipped with a crack-resistant impact detection head and an arch-shaped fixing seat. By driving the output shaft to the top motor to drive the support rod to adjust the clamping angle, the elastic support rod is used to alleviate the impact force, and provide impact force through the jet cylinder to reduce the impact on the fixed seat.

Benefits of technology

It realizes the provision of larger impact force under the smaller device size, reduces damage to the fixed seat, reduces maintenance costs, adapts to different sizes of aluminum alloy plates, and can perform rotary impact force detection, with various detection methods.
