Is provided with a drive shaft 19 common to the first door 8A and the second door 8B in the gear box 18 of the automatic tool changer 4, and one end thereof is connected to a drive source (not shown) of the automatic tool changer 4. . The sector gear 20 is fixed on the drive shaft 19, and the swing of the drive shaft 19 is transmitted via the driven gear 21 to the output shaft 22.
It is designed to be expanded and communicated. A drive sprocket wheel 23 is replaceably attached to the output shaft 22, and a chain 25 is wound around the sprocket wheel 23 and the driven sprocket wheel 24. The chain 25 is connected to the first door 8A via a connecting plate 26,

され、開口部７が全開される。Next, the operation of the door device constructed as described above will be described. When the standard tool Ta is exclusively used in the machining center, the auxiliary cover 15 is attached to the cover 3 as shown in FIG. When a tool change command is output in this state, the automatic tool changer 4 is driven and the change block 4a and the change arm start a predetermined tool change operation. At the same time, the drive source of the automatic tool changer 4 causes the drive shaft 19 of the door opening / closing mechanism 17 to swing in one direction, so that the first door 8A is driven by the drive sprocket wheel 2.
By sliding with a stroke corresponding to the number of teeth of 3, the opening 7 is opened with an opening slightly wider than the length of the standard tool Ta, through which the standard tool Ta passes and is replaced with a front tool on the spindle. At this time, the second door 8B is also opened in synchronization with the first door 8A, but the opening 7 of this portion is closed by the auxiliary cover 15, so that the cutting space 2 is cut with the standard tool Ta.
Can be opened with the minimum necessary size that can pass through. After the tool change, the drive shaft 19 is rotated in the reverse direction, and the first door 8
A and the second door 8B are closed, and the opening 7 is fully closed. Note that, as shown in FIG. 2, the four-bar linkage including the second door 8B and the arms 28 and 29 and the rod 30 may be removed. At this time, the auxiliary cover 15 is attached to the cover 3 in the space created by removing the second door 8B. As a result, the standard tool Ta can be opened with the minimum necessary width through which the standard tool Ta can pass. After the tool replacement, the drive shaft 19 is rotated in the reverse direction, the first door 8A is closed, and the opening 7 is fully opened.

To do so, the drive sprocket wheel 23 is replaced with a large diameter one having a large number of teeth. When the automatic tool changer 4 is driven in this state, the first door 8A is opened with a stroke slightly longer than the length of the long tool Tb as the drive shaft 19 swings, and the second door 8B is opened. Is opened to the inside of the cover 3 at the same angle as that of the standard tool Ta, the opening 7 is fully opened, and the long tool Tb is exchanged therethrough. At this time, since the door 8 is divided into two in the main shaft axis direction, the width of the first door 8A can be designed to be narrow, and the interference between the cover 3 and the first door 8A can be prevented without increasing the size of the entire machining center. can do. Further, in the closed state of the door 8, the second door 8B covers the opening 7 on the front end side of the first door 8A, so that the cutting space 2 can be provided without the auxiliary cover 15.
It can be fully closed without any problem.

とができる。As described above, in the door device of this embodiment, the common drive shaft 19 opens and closes the first door 8A and the second door 8B in synchronization. Therefore, the doors 8A and 8B can be easily synchronously controlled by the common drive source, and the door opening / closing mechanism 17 can be easily configured. Moreover, since the drive shaft 19 is driven by using the drive source of the automatic tool changer 4, it is not necessary to install a dedicated actuator in the door opening / closing mechanism 17, and this mechanism 17 can be easily retrofitted to an existing machining center with standard tool specifications. As a result, a new machining center that can be used for both standard and long tools can be inexpensively modified.
