AI Technical Summary
During use, existing aluminum alloy casting machining positioning fixtures are prone to chipping that falls into the movable groove, making cleaning difficult and potentially jamming the threaded rod and affecting normal rotation.
The support platform features a slotless structure, combined with a servo motor-driven bidirectional threaded rod and clamping plate. The servo motor moves the clamping plate closer to or further away for clamping. Rubber sheets are provided on the clamping plate to enhance stability, and the frame blocks debris, which falls directly onto the support platform for easy cleaning.
It ensures the threaded rod rotates normally, simplifies the cleaning process, improves clamping stability, avoids debris affecting processing, and is easy to operate.
