Abstract
Abstract A machining center equipped with an integral robot device having a manipulating hand capable of approaching a spindle of the machining center, a tool storing magazine mounted on a machine body, a workpiece supply table disposed on a floor in the vicinity of the machine body, and a work table of the machine body so that an exchange of cutting tools may be carried out by the manipulating hand between the tool storing magazine and the spindle, and so that an exchange of workpieces may also be carried out by the manipulating hand between the tool storing magazine and the work table.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
130 words
A machining center for automatically effecting machinings to a workpiece supplied from a workpiece supply table disposed on a floor in a vicinity of the machining center, comprising: a machine body including a rigid column, a vertical spindle head attached to said rigid column and incorporating therein a vertical spindle to which a cutting tool is removably fitted, and a work table on which a workpiece is removably mounted; a tool storing magazine fixed to said machine body for removably storing therein a plurality of cutting tools, and; a robot device integrally mounted on said machine body and movable for effecting a tool exchange between said tool storing magazine and said vertical spindle and a workpiece exchange between said workpiece supply table and said work table of said machine body.
Claim 2
Dependent Claim
130 words
A machining center for automatically effecting machinings to a workpiece supplied from a workpiece supply table disposed on a floor in a vicinity of the machining center, comprising: a machine body including a rigid column, a vertical spindle head attached to said rigid column and incorporating therein a vertical spindle to which a cutting tool is removably fitted, and a work table on which a workpiece is removably mounted; a tool storing magazine fixed to said machine body for removably storing therein a plurality of cutting tools, and; a robot device integrally mounted on said machine body and movable for effecting a tool exchange between said tool storing magazine and said vertical spindle and a workpiece exchange between said workpiece supply table and said work table of said machine body.
Claim 3
Dependent Claim
89 words
A machining center as claimed in claim 1, wherein said tool storing magazine is arranged so as to extend toward a position above said workpiece supply table, and wherein said robot device comprising: a first means for vertically moving said robot device along a vertical guide attached to said rigid column; a laterally extending robot arm turnable in a horizontal plane around a vertical axis; a second means for driving a turning of said robot arm, and; a manipulating hand attached to the tip end of said robot arm.
Claim 4
Dependent Claim
77 words
A machining center as claimd in claim 2, wherein said first means comprises a ball screw shaft engaged with a ball nut, both being incorporated in said robot device, and an electric servo motor for rotating said ball screw by means of a belt-pulley mechanism, and wherein said second means comprises a vertical turning shaft rotated by an electric servo motor, and a bracket by which said robot arm is fixedly attached to said vertical turning shaft.
