AI Technical Summary
The existing tool setting equipment has insufficient detection accuracy of the strain gauge body, which cannot effectively sense and convert the micron-level tool deformation. As a result, the tool setting equipment cannot accurately reflect the tool status, which affects the machining accuracy and product qualification rate, and limits its application in ultra-precision machining scenarios.
The strain gauge body adopts a Wheatstone bridge structure, combined with steel ball-tripod linkage and nested positive and negative power supply. Through modular layout, it achieves precise power supply and stable detection, ensuring efficient transmission and conversion of electrical signals. The induction energizing structure and strain sensing structure work together efficiently to eliminate deformation constraints and interference.
It enables precise detection of micron- and submicron-level tool deformation by the tool setter, improving machining accuracy and product qualification rate, expanding its application in high-end manufacturing, reducing equipment maintenance costs, and enhancing its ability to adapt to complex machining environments.
