Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of precision manufacturing equipment, and specifically relates to a large-middle-hole multi-angle five-axis rotary table. BACKGROUND

[0002] Five-axis rotary tables are important components in modern precision machining equipment and are widely used in the efficient and high-precision machining of various complex workpieces. Traditional five-axis rotary tables usually include an A-axis and a C-axis, where the C-axis is mainly used for rotational motion to achieve different angle machining requirements.

[0003] Disadvantages of the prior art:

[0004] 1. Middle hole design limitations:

[0005] Existing five-axis rotary tables often do not have a middle hole or have a small middle hole diameter in the C-axis assembly.

[0006] This design only meets the wire passing requirement and cannot achieve the reverse side machining of the workpiece, resulting in the need for additional clamping steps and reducing the overall machining efficiency.

[0007] 2. Large structure thickness:

[0008] Due to the structural limitations of the C-axis assembly, its thickness is generally large.

[0012] During multi-angle machining, angle deviation or insufficient precision problems may occur, affecting the quality of the final product.
