Two Station Automobile Generator Rotor Balancing Machine High Precision Automatic Balancer
The Two-Station Automatic Balancing Machine for Automobile Generator Rotors is a high-precision balancing system specially designed for automotive alternator rotor applications. The machine is compatible with generator rotors having diameters ranging from 69.3 mm to 108.7 mm, shaft lengths between 135 mm and 154 mm, and weights up to 5 kg. It can also measure rotors fitted with bearings. The balancing correction process is carried out using a dual-plane diagonal drilling method, with customizable de-weighting hole settings for the same claw pole configuration. To accommodate different rotor sizes and balancing requirements, the drilling head angle can be adjusted between 30° and 60°.
This Two-Station Automobile Generator Rotor Automatic Balancer is built with a sturdy mechanical structure and includes a balancing measurement system, electrical control unit, automatic testing and drilling correction system, dust collection unit, and multiple safety protection mechanisms. The measuring station features adjustable pedestals that can be repositioned according to the support distance requirements. The support rollers mounted on the pendulum frame are removable, allowing the machine to adapt to various support methods, including roller support and bearing support. The equipment is integrated with advanced dynamic balancing software that supports imbalance measurement, storage of initial and residual imbalance values, qualification assessment, automatic drilling correction, measurement result recording, and data upload functionality.
Key Features and Production Advantages
1. Soft bearing measuring structure and high-precision vibration sensor, good vibration resistance and repeatability.
2. The position of the measuring station pedestals is adjustable, thus compatible with the dynamic balance measurement of workpieces of different spans. The support rollers on the pedestal are removable, which can be adapted to roller support, bearing support and other support methods.
3. Lower bracket belt drive, convenient for docking with manipulator to load and unload materials to achieve automated production.
4. The angle of the de-weighting power head can be adjusted in the range of 30-60° to meet the balancing correction requirements for rotors of different sizes.
5. The self-developed dynamic balancing software has the functions of dynamic balancing measurement, qualification judgment, data saving, querying, exporting, printing, uploading of measurement results, etc. It also supports amplitude display.
6. The dynamic balancing software comes with alarm prompts, which is convenient to find the fault location.
7. The equipment can be connected to the MES system and can be added with specified functions as required by clients.
