摘要： The present invention relates to a printed circuit board presser device in a drilling machine. The board presser device is arranged such that it includes an axially movable upper-plate presser device which is provided on the outer side of a contact surface of the board presser device with a printed circuit board so that a top end surface of the upper-plate presser device extends to the side of a table beyond the contact surface; and an urging device for pushing the upper-plate presser device against the table by a force larger than an attraction force generated from the board presser device. With such construction, an upper plate is suppressed from floating during drilling the printed circuit board, and a distance of useless transfer movement of a drill decreased, to thereby improve an efficiency of a drilling operation.

摘要： A spindle and Z-axis unit comprises a spindle housing and a hollow rotor shaft rotatable and axially movable with respect to the spindle housing. The rotor shaft carries a collet at its lower end for chucking a machine tool such as a drill bit. The tool is changed in the collet by pneumatic actuation of a diaphragm which actuates a push rod within the rotor shaft to move the collect axially against a spring bias to clamp and unclamp the tool. The shaft is moved in the Z-direction along with a thrust bearing assembly by a screw nut which actuates a road to move the rotor shaft in the Z-direction to drill a workpiece after a pressure foot has first been moved to clamp the workpiece with respect to the spindle. Thus, the moving weight or mass previously attributable to parts such as a spindle saddle and spindle housing can be eliminated without impairing the reliability and chucking force of the collet mechanism.

摘要： In a pressure foot used in an apparatus for drilling printed circuit boards, which includes a bearing for holding a spindle, and formed at the end portion thereof with an inner void space having a bottom hole for passing the drill bit, the end portion of the pressure foot is provided with an annular end surface possibly contacting with the printed circuit board and air injection ports for injecting compressed air into the inner space. The air injection ports are so directed that the air flow from each injection port is tangently contacts with the circumferential surface of the drill.
