Description

Technical Field

[0001] The utility model relates to the technical field of cutting heads, and specifically provides a unified three-dimensional five-axis cutting head. Background Art

[0002] There are limitations in the lightweight design of the slip ring of the three-dimensional five-axis cutting head, resulting in the structure of the cutting head not reaching the optimal state, thus affecting the performance of the cutting head in high-efficiency and high-precision machining.

[0003] This design limitation may increase the mass and complexity of the cutting head, reduce its stability and reliability, and thus have an adverse impact on the precision and efficiency in the machining process. Therefore, it is necessary to re-evaluate the design of the slip ring and seek more effective solutions to improve the performance of the cutting head. Summary of the Invention

A light guide cylinder is provided below the slip ring, and the slip ring is connected to a mandrel, which is connected to a C-axis motor. A cutting head vertical adjustment component is connected to the outside of the C-axis motor, and a cold water groove is arranged around the C-axis motor for cooling.

[0007] Further, the slip ring includes a slip ring rotating shaft and a slip ring housing. The slip ring rotating shaft is connected to the mandrel, and the slip ring housing is fixed on the C-axis base.

[0010] Further, the joint fixing component includes a mounting plate, a column, and a socket. The column is fixed on the upper part of the C-axis base and is arranged around the slip ring;

[0011] The socket is arranged on the mounting plate, and the wire of the slip ring housing is connected to the socket;

[0012] There are two mounting plates, and the two mounting plates are connected together by the column.

[0013] Further, the vertical adjustment component of the cutting head is used to adjust the verticality of the overall cutting head, and includes an adjusting nut, a bolt, a positioning nut, and a cutting head fixing plate. The bolt is connected to the C-axis base, and positioning nuts and adjusting nuts for adjustment are arranged around the cutting head fixing plate.
