Fan Blade Expandable Sleeve Balancing Machine Impeller Automatic Balancing Machine
The Expandable Sleeve Type Fan Blade and Impeller Automatic Balancing Machine is designed for the dynamic balancing and automatic material removal of hole-type plastic and aluminum alloy fan blades and impellers used in vacuum cleaners. It is suitable for workpieces with diameters ranging from 25 mm to 120 mm and center hole sizes between 1.5 mm and 8 mm, making it an ideal solution for precision balancing in high-volume manufacturing environments.
The machine features a high-precision expandable sleeve clamping mechanism that securely holds the workpiece during testing, ensuring excellent measurement stability and repeatability. With a repeat measurement accuracy of **±1 mg**, the system delivers highly reliable balancing results while accommodating components with varying bore sizes.
For balance correction, the equipment employs an automatic scissor-type material removal mechanism that precisely trims excess material based on the measured unbalance value. Compared with conventional manual balancing methods, this automated process offers greater accuracy, faster production speeds, and consistent correction quality, significantly improving manufacturing efficiency.
An advanced dynamic balancing software platform continuously records, displays, and exports process data throughout the balancing cycle. This comprehensive data collection enables production monitoring, quality traceability, and process optimization, providing valuable insights for improving product consistency and manufacturing performance.
Key Features and Production Advantages
1. High compatibility. The equipment is applicable for all kinds of hole type plastic and aluminium alloy fan blades/impellers with diameters from Φ25mm to Φ120mm and centre holes from Φ1.5mm to Φ8mm with weights from 10 to 200 g.
2. High production efficiency. The equipment can automatically complete the balancing initial test, automatic scissor remove material and re-testing processes. One person can operate 2-3 machines, saving labour cost.
3. Easy changeover. The structure of the workpiece fixture is simple, easy to disassemble, and the operator can do changeover independently through simple training.
4. High precision. Precision rising sleeve structure, high-precision acceleration sensor, customised data acquisition card with Zero Dynamic's self-developed high-precision dynamic balancing software, the precision of the equipment meets the ISO1940 G1, which meets the actual use requirements of most products.
