Abstract

A machining system including a base; multiple work modules arranged in an arrangement direction on the base, at least one of the multiple work modules being a processing module, which processes a work with a tool, provided with a main shaft head including a main shaft on which a tool is attached and a main shaft rotating device that rotates the main shaft; a head raising and lowering device that moves the main shaft head in a vertical direction; a head moving device that moves the main shaft head in a horizontal plane by moving it in two perpendicular directions; and a work table that holds a work; the processing module being configured so as to be pulled from the base along a path extending in an intersecting direction, which is a direction perpendicular to the arrangement direction.

Claims

1. A machining system comprising:

a base;

multiple work modules that are each arranged on the base on a common arrangement axis extending in an arrangement direction, at least one of the multiple work modules being a processing module, which processes a work with a tool, the processing module provided with;

(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 in a horizontal plane by moving it in two perpendicular directions; and

(D) a work table that holds a work;

the processing module having opposite front and rear portions that are spaced along an intersecting direction, which is a direction that is perpendicular to the arrangement direction, the work table being located on the front portion, the processing module being configured so as to be capable of being pulled frontward on the base along a path extending in the intersecting direction, and the processing module being configured to be pulled rearward on and from the base along the path extending in the intersecting direction to remove the processing module from the base.

2. The machining system according to claim 1, wherein

the processing module includes a tool magazine in which multiple tools to be attached to the main shaft are stored, and is configured to automatically exchange the tool attached to the main shaft with one of the multiple tools stored in the tool magazine,

the tool magazine including multiple tool holders each configured to hold a respective tool and arranged along an elongated ellipse that is elongated in the intersecting direction, and the processing module also including a tool holder circulating mechanism configured to circulate the multiple tool holders.

3. The machining system according to claim 2, wherein

the processing module includes

a module main body, the head raising and lowering device being supported on an upper portion of the module main body, and the tool magazine being housed inside the module main body, and

a magazine moving device that moves the tool magazine in the intersecting direction, and, when performing tool exchange, advances the tool magazine in the intersecting direction so as to protrude from a side surface of the module main body, and positions one of the multiple tool holders used for supplying a tool for exchange in a movement range in which the main shaft can by moved by the head moving device.

4. The machining system according to claim 1, wherein

the multiple work modules are arranged on the base closely adjacent to each other in the arrangement direction.

5. The machining system according to claim 1, wherein

each of the multiple work modules is capable of being drawn out from the base by being pulled rearward in the intersecting direction.

6. The machining system according to claim 1, wherein

the processing module includes a pair of wheels, and

the base includes a pair of rails provided extending in the intersecting direction,

the processing module being configured to be pulled from the base along the path by the pair of wheels of the processing module rotating along the pair of rails.

7. The machining system according to claim 1, wherein

the processing module is provided with a table rotating device that rotates the work table around at least one of a vertical axis that extends in a vertical direction, or a horizontal axis that extends in a horizontal direction.

8. The machining system according to claim 1, wherein

the base is configured to receive into the inside of the base shavings generated by processing of the work by the processing module, and the machining system includes a shavings discharge device configured to discharge from the rearward side of the base the shavings received by the base.
