AI Technical Summary
Existing six-dimensional force sensors use screws to secure the housing, which makes the disassembly and assembly process cumbersome and time-consuming. Frequent disassembly can cause thread wear or structural loosening, affecting measurement accuracy and sealing, and is not conducive to on-site maintenance and strain gauge replacement.
The system employs a quick-release assembly between the base plate and the cover plate, including a mounting shell, guide hole, slot, spring, slide bar, stop plate, and locking block, to achieve rapid locking and releasing of the cover plate and the base plate. Combined with the arrangement of the rhomboid strain beam and strain gauges, it forms a highly sensitive, low-coupling elastic deformation bridge circuit structure, which facilitates maintenance and strain gauge replacement.
It enables rapid sensor maintenance and high-precision measurement, lowers the maintenance threshold, avoids problems caused by screw connections, improves maintainability and measurement accuracy, and ensures structural reset accuracy and long-term stability.
