AI Technical Summary
After the existing cutting teeth wear down, the fit between the groove and the positioning ring decreases, resulting in inaccurate positioning and reducing the accuracy of wear measurement.
The design employs four sets of guide cylinders and limiting rods. Through the cooperation of the inclined surface of the limiting rod and the spring, stable support and positioning of the cutting teeth are achieved. Combined with the structure of the lifting ring and adjusting rod, it is easy to disassemble and measure. Precise measurement is performed using the measuring head and measuring disc.
It improves the accuracy of cutting tooth wear measurement, facilitates the operation of measuring tools, avoids positioning deviation caused by wear, and simplifies the disassembly process of cutting teeth.
