Machine guard pivot assembly - includes bracket with recess for limit switch operated by ball in pivot vee groove

摘要

Simplified mounting of guard on the machine with a limit switch for cutting off the supply when the guard is opened also combines safety against manipulation by the operator. This is achieved by fitting the actuator of the switch in a spot protected by the bearing of the guard pivot (3). The switch (17) is held in the recess of the bearing block (2) clamped by U-shaped bracket (10) to the column (11) of the machine. The guard (15) is supported by pivot (3) to which the slotted grippers (13) of the guard are attached. The pivot is axially located with its shoulder (4) and circlip (5) while the Vee recess (16) and cross hole (19) in the pivot and bracket contain balls (20) for operating the sensor of the limit switch.
