AI Technical Summary
Existing detection methods are affected by burrs and flash on the blank parting line, resulting in large measurement errors. They cannot accurately reflect the runout of the hydraulic chuck's three jaws, causing uneven allowance when machining trunnions, increasing the risk of product scrap, and also resulting in low measurement efficiency.
A device for detecting the coaxiality of the surface and inner diameter of a shaft hub blank is designed, including a base, a rotary positioning mechanism, a transverse motion mechanism, a longitudinal motion mechanism, and a dial indicator. The rotary positioning mechanism and the motion mechanism control the dial indicator probe to lightly touch the surface of the small-diameter hole and read the pointer change value, avoiding the influence of burrs and improving the measurement accuracy.
It achieves convenient operation, clear and intuitive measurement data, is not affected by burrs or flash on the blank parting line, improves measurement accuracy, reduces the risk of product scrap due to material shortage, and enhances the quality of three-pivot products.
