あつた。 In order to automatically exchange heavy tools that cannot be replaced with regular tool changers such as large face milling cutters, tool holders are installed on the workpiece table so that they can slide in a direction perpendicular to the spindle axis. A heavy tool is elastically held on the stand, and when changing the tool, the tool holding stand is moved to move the tool within the movable range of the spindle, and then the workpiece table and spindle are moved relative to each other by numerical control commands. A machine tool has been proposed in which a heavy tool is attached to a spindle, but in this machine, a slide base with a length corresponding to the amount of movement of the tool holder must be placed on the table. It requires a large installation space on top, which greatly reduces the work space available for machining workpieces, and has the disadvantage that large workpieces cannot be machined.

本発明はこのような従来の欠点に鑑み、少ない

で、以下その実施例を図面に基づいて説明する。 In view of these conventional drawbacks, the present invention is designed to allow a magazine for storing tools to be mounted on a workpiece table with a small installation space so that the work space on the workpiece table is not reduced. Examples will be described based on the drawings.

A tool magazine 22 is placed. As shown in FIG.
6, and a plurality of tool holding devices 28 that are attached to the mounting surface 27 of the rotating member 26 on the rotary table 12 side and hold the auxiliary tool TS parallel to the spindle axis. It is rotatably supported via a pivot 25a on a fixed plate 25 fixed at a position on the table 13 so as not to interfere with the machining operation in a plane orthogonal to the spindle axis. A cylinder 30 is fixed to the fixed plate 25 via a support arm 29.
A piston rod 31 of 0 engages with a drive pin 32 fixed to the pivot member 26, thereby causing the pivot member 26 to pivot.

る。 Further, a stopper 34 for restricting the counterclockwise turning end of the turning member 26 and a stopper 35 for restricting the clockwise turning end of the turning member 26 are fixed to the fixed plate 25. A retracted position shown by a two-dot chain line in FIG. 2 and a tool exchange position shown by a solid line in FIG. 2 are regulated by these stoppers 34 and 35, respectively. The retreat position is set to a position where the auxiliary tool TS held by the tool holding device 28 does not interfere with the work area, and the tool exchange position is set to a position where the auxiliary tool TS held by the tool holding device 28 is set to a position where the auxiliary tool TS held by the tool holding device 28
In order to make the position of the auxiliary tool TS the same in the left and right direction and to facilitate the positioning program when exchanging tools, the axis of the auxiliary tool TS held by the tool holding device 28 is aligned perpendicular to the upper surface of the workpiece table 13. Set. Note that, as shown in FIG. 3, the stopper 35 has a groove formed in the vertical direction that engages with a convex portion of the abutment member 36 fixed to the rotating member 26. is prevented from rotating in the direction of the spindle axis.

The gripping pawls 40, 41 are pivotably supported in the same plane as the rotating member 26 via the rotary member 39, and are opened toward the center of the workpiece table 13.
A spring 42 is provided between the support base 37 and the support base 37 to rotate the gripping claws 40 and 41 in the direction in which the opening is closed, thereby elastically gripping the auxiliary tool TS. The shaft 43 provided through the gripping claws 40, 41 and the support base 37 prevents the opening width of the gripping claws 40, 41 from being less than a predetermined width.

As shown in FIG. 2, the center positions of the gripping surfaces 40a and 41a are located a predetermined amount closer to the center of the workpiece table 13 than the pivot point of the rotating member 26, so that the auxiliary tool magazine When the tool 22 is located at the tool exchange position, the axis of the auxiliary tool TS gripped by the gripping claws 40 and 41 is located within the movable range of the spindle 16. Therefore, after rotating the auxiliary tool magazine 22 to the tool exchange position, by moving the spindle 16 relative to the workpiece table 13, the auxiliary tool TS stored in the tool holder 28 is attached to the spindle 16. or place the used auxiliary tool TS in tool holder 2.
You can return it at 8. The tool mounted on the spindle 16 is clamped and unclamped by an unillustrated tool gripping mechanism provided inside the spindle head 15.

安定した動作を行える利点がある。 As described above, in the present invention, the tool attached to the tool holding device is moved to a retracted position that does not interfere with normal work and within the movable range of the spindle by the rotating movement of the rotating member to which the tool holding device is attached. Since the tool magazine can be moved between the tool changing position and the tool changing position, the tool magazine can be mounted on the workpiece table in the space required to install the fixed plate that pivots the rotating member. It has the advantage that the work space available for machining workpieces is hardly reduced even if it is installed. In addition, in the present invention, since the tool is moved by a rotating motion, cutting debris does not adhere to the guide surface unlike the method in which the tool holder is moved along the guide surface of the slide base, and it can be used for a long time. It has the advantage of stable operation over a long period of time.

行なえる利点がある。 Furthermore, a stopper is provided on the workpiece table that comes into contact with the tool magazine at the tool attachment/detachment position to restrict the rotation of the tool magazine, and the tool magazine and stopper are formed with convex portions and grooves in the vertical direction that fit into each other, making it easier to change tools. This has the advantage that tools can be reliably exchanged between the spindle and the tool magazine without fear of major positional deviations.
