AI Technical Summary

Technical Problem

Conventional automatic pallet exchange devices for large machine tools face issues with uneven operation of clamping units due to time deviations in hydraulic or pneumatic pressure reaching the clamping units, leading to uneven clamping, tilting, and non-contact areas between pallets and pallet bases, which necessitate machining the entire assembly.

Method used

The device separates the clamping unit into a support guide part fixed to the pallet base and a moving guide part that moves up and down, minimizing the area where pressure needs to be applied, and allows detachable attachment of pallet collars and clamp shoes for uniform contact, enabling accurate clamping and unclamping.

Benefits of technology

This design ensures precise and uniform clamping/unclamping operations, reduces maintenance costs, and enhances productivity by minimizing non-processing time through efficient pallet exchange.
