Production washing assembly verification system and method

摘要

A master verification assembly includes a plurality of plunger devices. Each of the plunger devices includes a piston that is axially moveable between a raised position and a depressed position. When placed in a washing assembly, each of the plunger devices is aligned with a nozzle. The nozzles dispense a cleaning fluid under pressure. An axial force applied by the dispensed cleaning fluid depresses the pistons into the depressed position, whereupon the pistons disposed in the depressed position are axially secured in an indicator position. Upon removal of the master verification assembly from the washing assembly, depressed pistons in the indicator position indicate proper function of the nozzles, whereas pistons disposed in the raised position indicate improperly functioning nozzles.

主权项

1. A part washing system for washing parts, the part washing system comprising:
a washer assembly having a plurality of nozzles, wherein each of the plurality of nozzles is configured for dispensing a stream of a cleaning fluid under pressure; a master verification assembly including a plurality of plunger devices, with one of the plurality of plunger devices disposed opposite one single nozzle of the plurality of nozzles of the washer assembly; wherein the master verification assembly includes a body defining a plurality of apertures, with each one of the plurality of apertures configured to align with the stream of the cleaning fluid dispensed from a respective one of the plurality of nozzles of the washer assembly, and with one of the plurality of plunger devices disposed within a respective one of the plurality of apertures; wherein each of the plurality of plunger devices includes:
a housing defining a central bore extending along a longitudinal axis;a piston disposed within the central bore and moveable along the longitudinal axis between a raised position and a depressed position;wherein the piston is moveable from the raised position into the depressed position in response to an axial force having a magnitude greater than a pre-defined value applied by the stream of the cleaning fluid from the nozzle along the longitudinal axis; anda latch configured for securing the piston in an indicator position upon the piston moving into the depressed position.
