Abstract

A machining center including a machine main body, an upper section of which supports a head moving device and a head raising and lowering device, configured such that a tool magazine is stored inside the machine main body, and with a magazine moving device configured to move the tool magazine such that, during tool exchange, the tool magazine is advanced to protrude from a side of the machine main body, so that, from the multiple tool holders, the tool holder used for exchange is positioned inside the movement range of the main shaft by the head moving device, and wherein the entire tool magazine is able to be moved beyond the movement range of the tool magazine by the magazine moving device to a position outside of the machine main body and detached from the machine main body.

First claim

The invention claimed is:

1. A machining center comprising:
(A) a main shaft head including a main shaft on which a tool is attached and also including a main shaft rotating device that rotates the main shaft; (B) a head raising and lowering device that moves the main shaft head in a vertical direction; (C) a head moving device that moves the main shaft head within a movement range and in a horizontal plane by moving it in two perpendicular directions; (D) a work table that holds a work; and (E) a tool magazine for storing multiple tools and equipped with multiple tool holders that are each configured to hold a respective tool to be attached to the main shaft, one of the multiple tools stored in the tool magazine being able to be automatically exchanged with the tool attached to the main shaft;
a machine main body, an upper section of which supports the head moving device and the head raising and lowering device, the tool magazine being stored inside the machine main body, and
a magazine moving device configured to move the tool magazine within a movement range such that, during the tool exchange between the tool magazine and the main shaft, the tool magazine is advanced by the magazine moving device to protrude from a side of the machine main body, so that the tool holder used for the exchange is positioned, by the head moving device, inside the head moving device movement range of the main shaft, and
wherein the entire tool magazine is able to be moved to a position that is beyond the magazine moving device movement range of the tool magazine, at which position the entire tool magazine is outside of the machine main body, and is detached from the machine main body.

2. The machining center according to claim 1 , wherein
the magazine moving device includes a guide rail attached to the machine main body, and a guide engaging section that is fixed to the tool magazine and guided along the guide rail, and
the machining center is configured such that a temporary loading table with an extension rail that extends the guide rail can be fixed to the machining center so as to extend the guide rail, and the tool magazine moved onto the temporary loading table by being pulled along the extension rail.

3. The machining center according to claim 2 , wherein
the temporary loading table is provided next to a movable trolley, the machining center supports the temporary loading table, and with the temporary loading table in a supported state, the movable trolley is next to the machining center such that the guide rail is extended by the extension rail, allowing the tool magazine to be moved onto the temporary loading table by being pulled along the extension rail.

4. The machining center according to claim 1 , wherein
the multiple tool holders are arranged along an elongated oval, and the tool magazine includes a tool holder circulating mechanism that circulates the multiple tool holders.

5. The machining center according to claim 1 , wherein
the machining center is one of multiple work modules in a machining system, which machining system includes a base and multiple work modules arranged on the base in an arrangement direction.

6. The machining center according to claim 5 , wherein
the multiple work modules are arranged closely adjacent to each other in the arrangement direction.
