Embodiment Construction

[0017] Hereinafter, a tool magazine as an embodiment of the present invention will be described in detail with reference to the drawings.

[0018] 1 is a machining center equipped with a tool magazine 10, a table 3 is provided on a bed 2 in a manner to be slidable in the Y-axis direction (front-rear direction), and a slide table 4 is slidable in the X-axis direction (left-right direction) perpendicular to the Y-axis. ) is set on the bed 2 in a freely sliding manner. Further, a headstock 5 having a spindle 6 on the lower surface is provided on the front surface of the slide table 4 and above the table 3 so as to be slidable in the Z-axis direction (vertical direction) perpendicular to the X-axis and the Y-axis. Furthermore, on the right side of the table 3 is provided a tool magazine 10 for storing various tools T1, T2 . In addition, the main shaft 6 is rotatable around a C axis parallel to the Z axis. Furthermore, the sliding motions of the table 3 , slide table 4 , and head...

Abstract

A tool magazine includes: a rotary shaft; and a plurality of tool gripping members radially extending around the rotary shaft. The tool magazine is configured to transfer tools between the tool gripping members and a tool attachment portion of a machine tool. The plurality of tool gripping members are arranged such that two tool gripping members are at least partially adjacent to each other and disposed in different heights in a direction of the rotary shaft, so that a tool is transferred between one of the two tool gripping members and the tool attachment portion without interference of the tool attachment portion against a tool gripped by the other one of the adjacent tool gripping member.

Description

technical field [0001] The present invention relates to a tool magazine included in a machine tool such as a machining center, for example. Background technique [0002] Conventionally, in a machine tool such as a machining center that attaches tools to a spindle to perform machining, a tool magazine capable of accommodating multiple types of tools is provided, and tools can be exchanged between the tool magazine and the spindle (for example, Patent Document 1). [0003] Here, according to Figure 4 A general tool magazine will be described. The tool magazine 41 includes a plurality of arms 42a, 42b, . . . provided radially around a rotary shaft (not shown). Furthermore, the arm 42a can hold a small-diameter tool T1 in a posture parallel to the rotation axis (that is, a posture perpendicular to the arm), and the arm 42b can hold a large tool T1 in a posture parallel to the rotation axis (that is, a posture perpendicular to the arm). diameter tool T2. In this tool magazine...
