Abstract
Abstract An industrial robot adjustment device capable of adjusting the position of a tip end of an industrial robot easily to the origin assumed by software of the industrial robot. The adjustment is electrically carried out by the coupling of a jig positioned at a predetermined position relative to the robot and pins provided to a flange which is detachably mounted on an end portion of an operating arm of the robot.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
154 words
An industrial robot adjusting device for an industrial robot having at least one operating arm, comprising: a first member having at least three protrusions, which is detachably mounted to an end portion of said arm in such a manner that said first member is allowed to rotate about a rotation axis; a second member positioned at a predetermined position relative to said industrial robot, said second member being provided with a least three holes adapted to receive said protrusions corresponding thereto; and means for detecting insertion of said protrusions into said receiving holes to produce a detection signal said detecting means being respectively provided in a bottom portion of each of said holes such that said detection signal is produced upon contact with said protrusions; the position of the rotation axis when the detection signal is produced, being taken as the point of origin for manual data input (MDI) adjustment for said industrial robot.
Claim 2
Dependent Claim
154 words
An industrial robot adjusting device for an industrial robot having at least one operating arm, comprising: a first member having at least three protrusions, which is detachably mounted to an end portion of said arm in such a manner that said first member is allowed to rotate about a rotation axis; a second member positioned at a predetermined position relative to said industrial robot, said second member being provided with a least three holes adapted to receive said protrusions corresponding thereto; and means for detecting insertion of said protrusions into said receiving holes to produce a detection signal said detecting means being respectively provided in a bottom portion of each of said holes such that said detection signal is produced upon contact with said protrusions; the position of the rotation axis when the detection signal is produced, being taken as the point of origin for manual data input (MDI) adjustment for said industrial robot.
