[0002] In machining, automation equipment, and precision manufacturing, mechanical oscillating heads are key components for multi-angle machining and precise positioning of workpieces. Traditional mechanical oscillating heads are often limited to single-direction rotation, failing to meet the demands of complex workpiece machining. With technological advancements and the development of the manufacturing industry, the performance requirements for mechanical oscillating heads are becoming increasingly demanding. This is particularly true in applications such as five-axis machine tools, robotic arms, and medical equipment, which require oscillating heads capable of multi-degree-of-freedom rotation and high-precision positioning.

To address these issues, a simple, high-precision, and stable orthogonal mechanical pendulum is needed. This pendulum should be able to rotate 360° horizontally and 360° vertically to meet the demands of complex workpiece machining and precise positioning. Utility Model Content
