AI Technical Summary
The existing turbine housing positioning process is time-consuming and prone to damage from impacts, leading to the scrapping of turbine housing products and low work efficiency.
A turbine housing anti-collision positioning device was designed, including a protective cover and a positioning mandrel. The protective cover is fixed on the upper end of the positioning mandrel. The outer circle of the protective cover is used to position the inner circle of the upper end of the turbine housing. The positioning mandrel unit is tightly connected by a concave-convex structure. A guide positioning ring is used for guidance to avoid direct collision. The protective cover is made of MC nylon material to reduce hardness.
It enables quick clamping, avoids bumps and damage, and improves the yield of turbine housings.
