Mechatronic intelligent unit for tightness checking (negative pressure/vacuum) Reverse Module TL8 - machined

The testing intelligent unit is a mono-block construction and verifies the air loss from the pieces who composed the Reverse module (Power transfer unit)" The unit is made by three tightness checking machines air-air for three pieces: "body reverse module", "coupling reverse module" and "cover reverse module". These three pieces will be assembled in a block forming the "Reverse Module" also called "Power Transfer Unit". The unit has an automatic working cycle; The intelligent measuring program is set for each type of pieces; The measuring is made sequentially: "cover-coupling-body"; The pieces are set inside the machine, on the corresponding tightening plate; The pressure subassemblies press the pieces on the tightening plates; The tapered and clamping subassemblies pressurize the bores of the pieces; The ATEQ-cell introduces air in the obtained cavity of the piece (-0,5 bar);the admissible air loss must be under 0,25 cm³ /s; If the piece is good it\´s automatically marked; The machine is protected with immaterial barriers against the intruders over the function, in the work space. The access is admitted for loading the machine with pieces, only through the front. The all work-process of the machine is driven and monitored by a programmable automaton Siemens with a specialized controller; there is a continuous communication (man-machine) with final decision and feed-back The vacuum source and the pneumatic panel (with pneumatic elements for command) are part of the unit.
