PRINTED BOARD FIXING DEVICE

摘要

PROBLEM TO BE SOLVED: To improve machining efficiency and accuracy even in a printed board having small rigidity. SOLUTION: In this device, a proximity sensor 35 is arranged in the front surface of a clamper 11 supported movably in a horizontal direction by a pulse motor 33, to stop the rotation of the motor 33 before the sensor 35 abuts on the side surface A1 of a printed board A. A cylinder 12 is actuated in a condition where a gap is provided between the clamper 11 and the sensor 35, to fix the board A to a sub-table 20 by a clamper 11.
