AI Technical Summary
In the existing technology, it is difficult to keep the magnetic shaft and magnetic sleeve of the constant force magnetic spring aligned during the measurement process, which leads to a decrease in the accuracy of the magnetic force test results.
The system employs an alignment clamping assembly, a guide assembly, a distance measuring device, and a force measuring device. The clamping assembly keeps the relative position of the magnetic shaft and the magnetic sleeve constant, the guide assembly ensures alignment during axial movement, and the distance measuring device and the force measuring device measure the magnetic force value.
It improves the accuracy and precision of constant force magnet magnetic force measurement, with force accuracy up to 0.001N and distance accuracy up to 0.01mm.
