Van Dongen Engineering is your partner when it comes to combining different systems to solve your task.
Automatic pressing of cylinder liners into the crankcase with force path monitoring and protrusion measurement. Reading of DMC labelling and communication via the interfaces to the higher-level belt control.
Crankcase press-in measuring automation
This cylinder liner press-in automation is designed for the automatic detection of different crankcases for the press-in of the different liners. The different crankcases come unsorted over the runway from the previous station. On entry, the DMC code is read, the sequence programme is selected and the crankcases are automatically stopped and lowered at a defined position. The combined measuring and joining head is placed over the liner and lowered into the joining position until it comes to rest. The support blocks to prevent edge chipping are closed and the force-monitored joining process is carried out. The static protrusion measurement is carried out and the intermediate result is stored. This procedure is carried out at the other positions and after the last position the final evaluation is carried out. The measurement results are displayed on the screen and sent to the interface for further processing. The units move into rest position and the crankcase is lifted again and transported to the next station.
Calibration is carried out automatically via a setting master below the rest position of the measuring head and can be carried out in non-productive time.
Cylinder block measuring automation for cylinder bore
This cylinder block measuring automation is integrated into the customer’s production line and communicates with the higher-level process control via the interfaces. The cylinder block is separated on the infeed conveyor, stopped and the component data is read in via a DMC camera. After further transport below the measuring position, the cylinder block is lifted out, aligned via index pins and clamped in the measuring position. The measuring air is switched on, the component temperature is measured and the measuring sequence is started. Two cylinder bores (1 & 3) are measured simultaneously in different measuring positions and, after the measuring unit has cycled, the other cylinder bores (2 & 4) are measured. The measuring unit moves into rest position, the measuring air is switched off and the component is lowered. After the individual static measurements, the final evaluation takes place. The measurement results are displayed on the screen and sent to the interface for further processing. In case of a n.o.k. measurement, a second measurement is carried out and after an OK measurement, the cylinder block is sent to the next station. measurement, the cylinder block is transported to the next station or discharged.
Calibration is carried out automatically via two setting masters in the rest position of the measuring heads and can be carried out in non-productive time.
