Claims

[Scope of utility model registration request]

In a three-dimensional laser processing machine, the rotary cylinder is rotatably supported in a housing, and a connecting arm that intersects with the rotational axis of the rotary cylinder and is connected to a laser head is rotatably supported. with a cylinder,
The laser head support body is divided into two parts, and the laser head support body is provided with a connecting cylinder part on its upper part, and the upper part of this connecting cylinder part is formed into an inward flange part, and the lower end of the cylinder body is provided with a connecting cylinder part. Fitted into the connecting tube, the laser head support can be moved up and down, tilted,
and a rotatable flange-like engagement part, and urges the connection cylinder part downward to bring the inward flange into contact with the engagement part, so that the connection cylinder part and the engagement part are in contact with each other. A rotation locking portion is provided on one side, and a locking pin of a connecting cylinder portion that engages with and disengages from the rotation locking portion is provided on the other side and biased in the locking direction with the rotation locking portion, and A laser head safety device for a three-dimensional laser processing machine, characterized in that a detector for detecting displacement of the laser head support with respect to the cylinder is disposed on the upper surface of the connecting cylinder.
