Abstract

An automatic position adjustment system of the present disclosure includes a position detection unit configured to measure the position of an installation target object installed on a table as viewed from a reference position as a reference installation point, a control device configured to calculate a displacement between the position of the installation target object obtained by the position detection unit and viewed from the reference position and a proper target position in installation of the installation target object as viewed from the reference position, and a position adjustment unit configured to correct the position of the installation target object to the target position based on the calculated displacement.

First claim

1 . An automatic position adjustment system including a machining tool having a table and configured to adjust a position of an installation target object installed on the table, comprising:
a position detection unit configured to measure the position of the installation target object installed on the table as viewed from a reference position as a reference installation point; a displacement calculation unit configured to calculate a displacement between the position of the installation target object obtained by the position detection unit and viewed from the reference position and a proper target position in installation of the installation target object as viewed from the reference position; and a position adjustment unit configured to correct the position of the installation target object to the target position based on the displacement calculated by the displacement calculation unit.

2 . The automatic position adjustment system of claim 1 , wherein
the position detection unit is a contact stylus device, a non-contact distance measurement device, or an imaging device.

3 . The automatic position adjustment system of claim 1 , wherein
the position adjustment unit grasps and moves the installation target object to correct the displacement with respect to the target position.

4 . The automatic position adjustment system of claim 1 , wherein
the position adjustment unit moves, by pushing or pulling, the installation target object to correct the displacement with respect to the target position.

5 . The automatic position adjustment system of claim 1 , wherein
the position adjustment unit moves, in a state in which part of the installation target object is supported, the table to correct the displacement with respect to the target position.

6 . The automatic position adjustment system of claim 1 , wherein
the position adjustment unit repeatedly adjusts the position of the installation target object until the displacement with respect to the target position is within an acceptable value.

7 . The automatic position adjustment system of claim 1 , further comprising:
an automatic delivery unit configured to supply the installation target object onto the table of the machining tool.

8 . The automatic position adjustment system of claim 1 , wherein
the position adjustment unit is a robot or a loader.

9 . The automatic position adjustment system of claim 7 , wherein
the automatic delivery unit is a robot or a loader.

10 . The automatic position adjustment system of claim 7 , wherein
the position adjustment unit and the automatic delivery unit are formed of a single robot or a single loader.

11 . The automatic position adjustment system of claim 1 , further comprising:
a robot or a screwing device configured to fix the installation target object onto the table of the machining tool after adjustment of the position of the installation target object by the position adjustment unit.
