Engine production and assembly


This project includes 600 screw driving channels, both single and multiple screw driving units are installed. Several of these units are equipped with a monitoring system in regards to process safety. The EST user interface displays the actual bolt position.

After finishing a screw driving operation, the status of the bolt joint is displayed by color change (ok or not ok). Using absolute position measuring systems the position of a bolt joint can automatically be parameterized/teached by the EST system software. Position measuring systems can be connected directly to the EST screw driving controller, for example via Profinet interface.

For communication with central control systems a standardized Profinet interface is used, which is identical for all screw driving channels (automatic stations and hand held units).


This station automatically joins the balance shaft (BS) to the crankcase (CC). The BSs are provided at the pick-up position by an automatic storage system. Once the workpiece carrier (WC) has reached its position in the station, the centering pin moves through the bearing positions at the CC into the center of the BS. The BS is now inserted into the CC using the forcipate joining unit. This joining movement is performed by the NC axis mentioned above. During the movement the force progression over the stroke is monitored by several programable control masks.

The joining process is extremely sensitive and places therefore challenging technical requirements on mechanical engineering and monitoring systems. Project planning and supply of components by EST did not only include the entire control system but also the integrated force and position measuring technology, which is based on the flexE12 system.
