Abstract
A gear train locking mechanism for preventing the reciprocating slide of a mechanical power press from inadvertently moving during maintenance procedures and the like is disclosed. The gear train locking mechanism preferably includes an idler gear which is enmeshed with a drive gear of the power press and a movable arm assembly positioned for selectively engaging the idler gear to prevent its rotation. The engagement of the arm assembly and the idler gear effectively locks the gear train of the power press thereby preventing the slide of the power press from moving once the locking mechanism is activated.
Claims19
For use in a power press having a gear train including at least one drive gear, a gear train locking mechanism for securing the at least one drive gear of the power press in a locked position, the gear train locking mechanism comprising, in combination:
- an idler gear enmeshed with the at least one drive gear of the power press for rotation therewith;
- a movable arm assembly including gear engaging means positioned for selectively engaging the idler gear;
- and,
- a first jack for translating the gear engaging means of the movable arm assembly into engagement with the idler gear to prevent rotation of the idler gear and the at least one drive gear.
For use in a power press having a gear train including at least one drive gear, a gear train locking mechanism for selectively preventing the power press from cycling comprising, in combination:
- a housing;
- an arm assembly supported within the housing by a first jack and a second jack, the arm assembly including gear engaging means, the first jack translating the arm assembly in a first plane between a home position and an extended position, the second jack translating the gear engaging means of the arm assembly in a second plane between a disengaged position and an engaged position;
- and,
- an idler gear engaging the at least one drive gear of the power press, the first and second jacks selectively translating the gear engaging means of the arm assembly into operative engagement with the idler gear to prevent the at least one drive gear of the power press from rotating.
A gear train locking mechanism for use in a power press having a reciprocating slide for performing operations on a workpiece disposed within a work area, and a gear train having a drive gear for driving the reciprocating slide through a workcycle, the gear train locking mechanism comprising:
- an arm assembly supported by an extending jack and an engaging jack, the extending jack translating the arm assembly in a first plane between a retracted position and an extended position, the engaging jack translating the arm assembly in a second plane between a disengaged position and an engaged position,
- an idler gear enmeshed with the drive gear of the power press, and,
- a control system for monitoring the position of the arm assembly and for providing the extending and engaging jacks with control signals to selectively translate the arm assembly into engagement with the idler gear to prevent the drive gear of the power press from rotating and the reciprocating slide from cycling.
