AI Technical Summary
The clamping force of existing probe-type quick-change test cabinets is fixed and cannot be adjusted adaptively, which increases the risk of workpieces falling off during long-term use, affecting test accuracy and product quality.
The initial clamping is achieved by driving the lead screw to rotate with a motor. The clamping force is adjusted by manually turning the lever through the inclined plane transmission. The clamping force is dynamically adjustable by using springs and triangular parts, ensuring a combination of basic fixed clamping force and dynamic adjustment.
It achieves dynamic adjustment of clamping force, improves test stability and clamping effect, simplifies operation, reduces the risk of workpiece falling off, and ensures test accuracy and product quality.
