Abstract

The invention belongs to the field of nontraditional machining, and discloses a precise numerical control indexing rotating shaft for electric discharge machining, which comprises a main shaft body, a permanent magnet alternating current servo torque motor which is connected with the main shaft body, and a grating encoder which is arranged at the upper end of the main shaft body; a brake apparatus is arranged on the main shaft body for controlling the main shaft body to stop rotating; the bottom end of the main shaft body is provided with a power device for supplying power for an electrode which is arranged at the center of the bottom end of the main shaft body; and a main shaft liquid cooing device is arranged on the main shaft body, and the liquid is filled from the outer part of the main shaft body for heat exchanging and flushing of the main shaft body. The precise numerical control indexing rotating shaft and a high-speed rotating shaft are designed into a whole, accessories are not needed to change for the precise indexing machining and the high-speed rotating machining, accordingly, the machining efficiency is improved, and a tool electrode and a workpiece can be automatically changed; and in addition, the precise numerical control indexing rotating shaft adopts an integral structural design and a shortened transmission chain, and has no backlash and higher indexing accuracy and servo response performance.

Description

technical field [0001] The invention belongs to the technical field of special processing, and in particular relates to a precision numerical control indexing rotary shaft for electric discharge machining. Background technique [0002] Precision CNC indexing axis (referred to as C-axis) is a special accessory for precision CNC EDM machine tools, also known as U-axis, which is controlled by the CNC system and can perform precise angular positioning and rotational servo processing, and can also be used with the linear axis of the machine tool For linked processing, the linear axes of the machine tool include the X-axis and Y-axis that are perpendicular to each other in the horizontal plane, and the Z-axis that is perpendicular to the plane where the X and Y axes are located. The C-axis is linked with the Z-axis, which can process similar parts such as internal and external threads, internal and external helical gears, and spiral curves; the C-axis is linked with the X and Y ax...
