DOUBLE-TURN ANGULAR SPINDLE HEAD Russian patent published in 2025 - IPC B23Q5/40 B23C1/12 

FIELD: machine building.

SUBSTANCE: invention relates to machine building and can be used in designs of double-turn angular spindle assemblies. In the spindle assembly, the rotary shaft of the axis A is connected to the spindle head by means of a flange on the end surface to perform rotation along the axis A, wherein the crank mechanism consisting of the first rotating shaft, the second rotating shaft, the rotating shaft of the B axis and the rotary connecting rod rotates the axis B under the action of the extension-retraction mechanism of the axis B. When exposed to the linear extension-retraction mechanism, the slider moves along the linear axis relative to the carriage and the spindle head rotates accordingly.

EFFECT: use of the invention provides expansion of technological capabilities of the assembly and increased accuracy of installation of the spindle head at simultaneous reduction of its dimensions and weight.
