AI Technical Summary
Existing grinding devices suffer from insecure fixing and large deviations when securing the car water pump shaft, resulting in low grinding accuracy. Furthermore, installation and disassembly are time-consuming, affecting production efficiency and precision.
The self-adaptive clamping mechanism uses a compression spring to achieve clamping, combined with an anti-slip texture design, to ensure that the water pump shaft does not shift during grinding. The power shaft is coaxially set with the clamping seat to ensure that the grinding wheel is in perpendicular contact with the surface of the water pump shaft. The stand is connected to the base via a slide rail, and the motor position is adjustable to adapt to different water pump shaft sizes.
It improves grinding precision and efficiency, ensures grinding uniformity and consistency, adapts to the rapid replacement of water pump shafts of different diameters, reduces downtime, and enhances production flexibility and applicability.
