Abstract

A machine tool system includes a machine tool including a processor to process a workpiece with a tool, and a bed on which the processor is mounted, a transport apparatus including two, left and right, legs spaced apart from the bed to transport the workpiece and feed the workpiece to the processor or discharge the workpiece from the processor, and a plate that connects the bed to the legs and is elastically deformable. The plate is upright such that a plate surface is aligned with a front-rear direction, and a connection portion of the plate that connects with the bed and a connection portion of the plate that connects with the legs are displaced in a front-back direction.

First claim

The invention claimed is:

1. A machine tool system comprising:
a machine tool including a processor to process a workpiece with a tool, and the machine tool including a bed on which the processor is mounted;
a transport apparatus including two legs spaced apart from one another in a front-rear direction and also spaced apart from the bed, the transport apparatus being configured to transport the workpiece and feed the workpiece to the processor or discharge the workpiece from the processor; and
a plate that connects the bed to the legs and is elastically deformable;
wherein the plate is upright such that a plate surface is aligned with the front-rear direction; and
a connection portion of the plate that connects with the bed is displaced in the front-rear direction from connection portions of the plate that connect with the legs.

2. The machine tool system according to claim 1 , wherein
the processor includes a main spindle to hold and rotate the workpiece; and
the tool is movable in a left-right direction that is transverse to the front-rear direction to regulate a depth of cutting in the workpiece being rotated.

3. The machine tool system according to claim 2 , wherein the processor includes a tool turret on which the tool is provided, and wherein plural additional tools are provided to the turret.

4. The machine tool system according to claim 3 , wherein the tools comprise cutting tool bits and/or end mills.

5. The machine tool system according to claim 1 , wherein the legs are in contact with a mounting surface on which the bed is mounted.

6. The machine tool system according to claim 1 , wherein the legs are spaced apart in an up-down direction from a mounting surface on which the bed is mounted.

7. The machine tool system according to claim 6 , wherein the plate has a rigidity such that the plate is capable of receiving a load of the transport apparatus in a vertical direction.

8. The machine tool system according to claim 6 , wherein the bed includes a support in contact with the mounting surface; and
the legs are directly above or in a vicinity of a position directly above the support, and wherein the legs are spaced apart from the bed.

9. The machine tool system according to claim 1 , wherein an additional leg is provided, and is spaced from the front leg in a left-right direction that is transverse to the front-rear direction, and a further additional leg is provided spaced from the rear leg in the left-right direction.

10. The machine tool system according to claim 1 , wherein the connection portion of the plate that connects with the bed is between the connection portions of the plate that connect with the two legs.
