WORK SEATING DETECTION DEVICE AND ADJUSTMENT METHOD FOR SAME
First Claim
1. :
- A work seating detection device comprising;
a detection hole formed to discharge air from a work seating face of a chuck gripping a work;
a detection flow path connecting an air supply source supplying the air at a predetermined pressure and the detection hole to each other,a pressure switch detecting a secondary-side pressure of a throttle portion formed in the detection flow path; and
a pressure regulator adjusting the secondary-side pressure,wherein an adjustment flow path branching on a secondary side of the throttle portion is formed in the detection flow path,wherein an on-off valve is disposed at any position of the adjustment flow path,wherein an adjustment block provided with an adjustment face pressing an adjustment gauge is integrally formed in a tip portion, andwherein an adjustment hole having the same size as the detection hole and communicating with the adjustment flow path is formed in the adjustment block for an opening portion to be positioned in the adjustment face.

Abstract
A work seating detection device including a detection hole formed to discharge air from a work seating face of a chuck, a detection flow path connecting an air supply source supplying compressed air and the detection hole, a pressure switch detecting a secondary-side pressure of a throttle portion formed in the detection flow path, and a pressure regulator adjusting the secondary-side pressure is provided. An adjustment flow path branching on a secondary side of the throttle portion is formed in the detection flow path, an on-off valve is disposed at the adjustment flow path, an adjustment block provided with an adjustment face pressing an adjustment gauge is integrally formed in a tip portion, and an adjustment hole having the same size as the detection hole and communicating with the adjustment flow path is formed in the adjustment block for an opening portion to be positioned in the adjustment face.

5. :
- An adjustment method for a work seating detection device including a detection hole formed to discharge air from a work seating face of a chuck gripping a work, a detection flow path connecting an air supply source supplying the air at a predetermined pressure and the detection hole to each other, a pressure switch detecting a secondary-side pressure of a throttle portion formed in the detection flow path, and a pressure regulator adjusting the secondary-side pressure, in which an adjustment flow path branching on a secondary side of the throttle portion is formed in the detection flow path, an on-off valve is disposed at any position of the adjustment flow path, an adjustment block provided with an adjustment face pressing an adjustment gauge is integrally formed in a tip portion, and an adjustment hole having the same size as the detection hole and communicating with the adjustment flow path is formed in the adjustment block for an opening portion to be positioned in the adjustment face, the adjustment method comprising;
allowing a virtual work to be gripped by the chuck such that the detection hole is blocked by the virtual work having a flat abutting surface being allowed to abut against the work seating face; allowing the adjustment gauge with a groove where an adjustment groove discharging the air from the adjustment hole is formed to abut against the regulation surface; and operating the pressure regulator such that the secondary-side pressure changing depending on a size of the adjustment groove of the adjustment gauge corresponds to a predetermined set value. - View Dependent Claims (6)
