Unidirectional rotation servo turret

Abstract

The invention relates to a unidirectional rotation servo turret. The unidirectional rotation servo turret comprises a box body; a cutter head, a servo motor and a main shaft are arranged on the box body; a main gear, a cam, a disc spring and a one-way clutch are arranged on the main shaft; the servo motor drives the main gear through a transmission assembly to drive the main shaft to rotate; the disc spring abuts against one side of the main gear; a plurality of protruding blocks are arranged on the other side of the main gear; grooves are formed in the cam and correspond to the protruding blocks; and each groove comprises a straight face section and an inclined face section. All-electric driving and servo motor driving are adopted, operation is more accurate, a hydraulic system is not needed, connection with a machine tool is simple and reliable, environmental friendliness is achieved, reverse rotation of the turret is limited by adopting the one-way clutch inside instead of using an electromagnet or one-way limiting pin, the structure and action are simpler and more reliable, control is convenient, and noise is avoided.

Description

technical field [0001] The invention relates to the technical field of numerically controlled lathes, in particular to a one-way rotary servo turret. Background technique [0002] The servo turret is an automatic tool changer for CNC lathes. When the CNC lathe needs to change the tool during use, first use the annular hydraulic cylinder of the servo turret to push the annular piston on the cutter head shaft to move forward in the axial direction, and drive the cutter head shaft and the cutter head to move forward in the axial direction, so that The movable end toothed disk on the cutter head is separated from the cutter head and meshed with the fixed end toothed disk, and then the rotary drive device of the cutter head shaft is used to drive the rotation of the cutter head shaft, so that the new tool used in the next processing step can be transferred to the work more accurately. position, and then use the annular hydraulic cylinder to push the annular piston on the cutterh...

AI Technical Summary

Problems solved by technology

[0003] However, the locking system of the servo turret in the prior art is generally driven by hydraulic pressure and needs hydraulic system support; not only the pipeline is complicated, but also easy to leak, causing cutting fluid or environmental pollution, and the reliability is low when the hydraulic components are not selected properly.

The all-electrically driven turrets are driven by ordinary asynchronous motors, which have poor precision and need to use electromagnets or one-way limit pins to control the forward and reverse rotation of the turret. The structure is complex, the reliability is poor during operation, and it will cause large noise
