| Abstract:Electric spindle is the core component and main power source of precision machining. Its performance directly dicates the machining accuracy, surface quality, processing efficiency and overall quality, which is of utmost importance to development of high-end equipment manufacturing industry. Electric spindles for precision machining are widely used in aviation, aerospace, shipping and
other fields, providing an important guarantee for precision parts machining and an important support for the development of modern high-tech industries. The dynamic performance test of electric spindles for precision machining is the key link to test its dynamic performance, life and reliability. For the traditional dynamic performance test often fails to accurately replicate real-world operating conditions, leading to limitations such as low testing efficiency and insufficient accuracy of the result, put forward an electric spindles for precision machining’s dynamic performance test device. The device can simulate the electric spindles for drilling, milling, deburring operation of the real working conditions; based on the data collected by the sensor, analyze and evaluate the performance of the bearing stiffness, life, wear and tear state. Under the premise of ensuring the stability of the structure, the topology of the clamping structure is optimized to achieve an overall weight reduction while balancing cost-effectiveness. The accuracy and reliability of the test device is verified through the test, and it can be applied in the dynamic performance test experiment of electric spindles for precision machining. |
