Description

Technical Field

[0001] The utility model relates to the technical field of a moving knife turret structure, and more specifically to a power turret for a numerically controlled machine tool. Background Art

[0002] The power turrets used in CNC machine tools are all driven by servo motors for indexing, which have the advantages of relatively simple structure and fast tool changing speed. However, in actual use, the turret needs to be positioned inside the tool head mounting cavity before it can be installed with the tool. It cannot be directly positioned with the tool, which reduces the efficiency of tool replacement. Moreover, after the turret completes the tool replacement and processing angle adjustment, it cannot automatically and quickly position, which brings certain inconveniences to the user.

[0003] For example, publication number CN116748544A discloses a power turret for a CNC machine tool, which includes a turret housing and a first servo motor fixedly installed on a motor fixing seat, the first servo motor is connected to a transmission shaft, the transmission shaft is clamped with a power tool transmission shaft, a piston shaft and a first fixed plate are arranged inside the turret housing, a connecting shaft is installed in the middle of the first fixed plate, and a shaft gear is sleeved on the outside of the connecting shaft.

[0004] It can be seen from the above-mentioned public scheme that when installing the tool, it is necessary to rotate and adjust the position of the tool head mounting cavity and the tool head clamping groove before it can be installed and positioned with the tool, which reduces the efficiency of tool replacement. Moreover, after completing the replacement and rotation adjustment of the tool, the engagement of the gears may cause the tool to rotate automatically during processing, and its rotation position needs to be additionally fixed to ensure the stability of the tool's adjustment position, which brings inconvenience to the user.
