AI Technical Summary
Traditional five-axis machine tool swivel head rotation structure suffers from lag response, machining vibration displacement, and loss of lock-up after power failure, failing to meet the requirements of high-precision and high-speed machining, and is also complex in structure and difficult to assemble.
It employs a gear locking mechanism, lifting assembly, and buffer mechanism, with slide rail guidance and spring providing clamping force to achieve high-strength, short-path locking. Combined with a rotating frame and drive mechanism, it provides stable rotation and rapid reset, enhancing processing accuracy and efficiency.
It achieves high-precision and high-efficiency five-axis linkage machining, is suitable for compact high-speed machining heads, improves machining quality and stability, and solves the problems of response lag and assembly difficulties in traditional structures.
