Balancing Machine for Crankshafts
- Universal machine concept
- Automatic unbalance measurement
- Precision positioning during correction
- Microprocessor-controlled measuring unit
Design
Two-station machine with separate measuring and correction stations. Measuring station with coupling-free roller-drive or hook drive for asymmetrical crankshafts.Correction station with positioning equipment and electro-mechanical drilling equipment.
Range of application
Measurement and correction of unbalance in machined passengervehicle and light commercial- vehicle crankshafts. Use in small and mid-volume series production or as a repair balancing machine.Unbalance correction by drilling into the counterweights in one or more steps at a separate drill stand (correction station). Manual handling of the work-pieces between measuring and drilling stations.
Sequence of operations
- Load a crankshaft into the measuring station, manually or by lifting device
- Close the protective shroud. Automatic measuring run and display measured values.
- Open the protective shroud and move the crankshaft to the correction stand.
- Insert the crankshaft into positioning device and couple with angleencoder for optional indexing aid or with locking-pin device
- Drill correction holes one after another corresponding to the display
- Return the crankshaft to the measuring station. Automatic check run and display of residual unbalance.
- Remove the crankshaft. If the crankshaft is still out of tolerance proceed with a second step.
