Fully-automatic system for assembly and measurement of front and rear axle transmissions. The transmission is indexed with a workpiece carrier and is fed via a belt system.
Drive bevel gear and drive flange assembly system
Gear box housing, drive bevel gear and inner bearing rings for the drive bevel gear are taken from the workpiece carrier by a robot grabber and placed in the system.
Measuring station driving pinion
After the manual insertion of the bevel gear, the diameter of the head bearing outer ring, the pinion height and the runout are measured under the load of the drive bevel gear in order to determine the thickness of the shim (S1) for the given block dimension (distance between pinion head and pinion shaft axle) - for the further assembly process.
Measuring station transmission housing
Measurement and control of the identification and quality values such as bore diameter, depth and angularity of the bore axes. The machine has two automatically exchangeable measuring heads for different housings. Independent calibration takes place using a gauger.
The base plate with floating suspension of the Lanchester grabber enables precise joining of the Lanchester in the index bores of the crankshaft housing. After the joining, the Lanchester is fastened on the crankcase housing automatically (torque and angle of rotation are monitored). The measuring and drive unit are combined as a single unit on the crankshaft.
