Description

Technical Field

[0001] This utility model relates to the field of anti-collision beam processing fixtures, and in particular to an automotive anti-collision beam sawing fixture. Background Technology

[0002] The car anti-collision beam is a core component of the vehicle's passive safety. It needs to be sawed to achieve a "fixed length and fixed shape" to match the body width of different models and avoid chassis components.
