DESCRIPTION OF THE AUTOMATED PROCESS

1. The operator places the MAN steering wheel lock assembly into the loading jig. The loading jig is shaped so that the lock assembly cannot be inserted the wrong way.
2. Once inserted, the operator attaches 2 spacer cylinders to the studs and secures the lock assembly with manual locking levers. This prepares the jig for entry into a temperature test chamber of -40°C to +90°C, including 95% humidity. The jig is equipped with wheels in the front part to facilitate entry into the chamber; the back has adjustable legs.
3. After entering the temperature chamber, the operator ensures the leeway of the connecting cables between the jig and trolley, which is outside the temperature chamber, and connects them using HARTING connectors. The trolley is equipped with an operator panel for controlling the jig in the temperature chamber. The cycle is constantly repeated according to the selected program.

BASIC CHARACTERISTICS

The machine is designed as a test station. It consists of a main aluminum frame and stainless steel mobile table, a mobile test plate for the MAN steering lock rods and the necessary cabling. The inserted lock assembly is placed on a POKA YOKE bed and manually secured by the operator. The status of the machine is displayed by the operation panel and indicators. From the point of view of safety, this machine is designed to work within the enclosed space of the temperature test chamber, and so it is not equipped with a special cover, door, etc.
