Abstract
A position compensation system of a tool changer includes a storage unit for storing a coordinate indicating a reference position of a turret, a rotary position coordinate detector for detecting the rotary position coordinate of the turret, a compensation necessity determiner for determining whether or not it is necessary to perform a rotational compensation to return the turret to the reference position, in accordance with a rotational deviation of the detected rotary position coordinate from the stored rotary position coordinate, and a compensation request part for requesting an operation or work related to the rotational compensation when it is determined that the rotational compensation needs to be performed.
Claims8
A position compensation system of a tool changer including a turret in which a plurality of grips capable of holding tools to be attached to a spindle of a machine tool are arranged along a circumferential direction, and a rotary driver that rotationally drives the turret about a rotary shaft to index an arbitrary one of the grips,
- the position compensation system comprising:
- a storage unit configured to store a rotary position coordinate of the turret corresponding to an index position of the grip as a coordinate representing a reference position of the turret;
- a rotary position coordinate detector configured to detect the rotary position coordinate of the turret;
- a compensation necessity determiner configured to determine whether or not it is necessary to perform a rotational compensation to return the turret to the reference position, in accordance with a rotational deviation of the rotary position coordinate of the turret detected by the rotary position coordinate detector from the rotary position coordinate of the turret stored in the storage unit;
- and
- a compensation request part configured to request an operation or work related to the rotational compensation when the compensation necessity determiner determines that the rotational compensation needs to be performed.
