AI Technical Summary

Technical Problem

In the existing lifting and gantry beam locking mechanism, there are two parts of the locking force transmitted from the hydraulic cylinder to the locking wheel, which causes cross beam vibration and up and down deviation during the machine tool to reduce the machining accuracy.

Method used

A hydraulic locking mechanism of lifting gantry beam including hydraulic cylinder, piston telescopic rod, top block, compression lever, locking bearing, support block, copper pressure plate, tapered washer and spherical washer was designed, and the output of the hydraulic cylinder washer is passed. Concentrated force transmission reduces force loss and achieves stable locking of the cross beam.

Benefits of technology

The locking mechanism ensures that the cross beam does not cause vibration or upward deviation in a fixed position, maintains processing accuracy, reduces the output force loss of hydraulic cylinders, and has a simple structure and a lower cost.
