AI Technical Summary
In existing technologies, thread surface grinding and polishing suffer from low production efficiency, high labor costs, and poor working environment, and there is a significant gap between domestic and foreign countries in terms of thread roughness.
A simple jet polishing device was designed. By setting a jet notch and a storage area in the inner cavity of the casing, the fluid polishing agent is driven by the rotation of the drive wheel to obtain high-speed kinetic energy, which impacts the surface of the part to be polished, so as to achieve uniform polishing. The accuracy is improved by adjusting the relative position of the part and the outlet of the flow channel.
It achieves uniform grinding and polishing of complex-shaped outer surfaces, improves production efficiency, reduces labor costs, improves the working environment, and reaches the same level of thread roughness as foreign countries.
