AI Technical Summary

Technical Problem

Existing high-temperature brazing fixtures suffer from thermal deformation or gaps due to differences in the thermal expansion coefficients of materials during high-temperature processes. Insufficient clamping force leads to welding defects such as incomplete welds, off-center welds, and missed welds, affecting welding quality and product reliability.

Method used

The lower and upper components are connected by connecting columns, and combined with high-temperature heat-resistant springs and stainless steel pressure blocks, it is designed as an elastic adjustment mechanism to provide continuous and stable clamping force, adapt to changes in thermal expansion, and prevent the product from loosening or shifting.

Benefits of technology

It enables automatic adjustment of clamping force during high-temperature brazing, improving welding consistency and reliability, preventing product loosening or displacement, and is suitable for rapid assembly and disassembly of various specifications of components, reducing maintenance costs and improving production efficiency.
