Description

Technical Field

[0001] The utility model belongs to the technical field of machining, and particularly relates to a single-motor reversible turntable. Background Art

[0002] In the field of machining, turntables are very commonly used components, especially when machining workpieces with arc structures or centrosymmetric structures such as gears and impellers. Most existing turntables do not have an overall flipping function, making it difficult to machine complex curved surfaces, or the flipping shaft requires an external motor for driving, greatly increasing the required installation space and transportation space, restricting the machining range applicable to the machine tool, and at the same time reducing the transportation efficiency. For some smaller machine tools, their worktables often do not have enough space to install multiple motors, and it is also difficult to adjust the levelness; for some specific workpieces, the extra motors are extremely likely to interfere with them regardless of their positions, or there is a risk of tool collision. Therefore, for a reversible motor, it is necessary to design a single-motor turntable that can reduce volume, lower costs, and is safe and reliable. Content of the Utility Model
