Abstract

The invention discloses a high-speed main shaft complete machine intelligent dynamic balance device which comprises a main shaft system fixed connecting part, a rotor automatic clamping and rotating part, a laser automatic aligning and de-weighting part and an unbalance detecting part. A high-speed main shaft of the main shaft system fixed connecting part is fixed to a main shaft positioning base. A vibration testing core bar is installed at the front end of the main shaft. A pneumatic claw of the rotor automatic clamping and rotating part can automatically clamp the vibration testing core bar and can be fixedly connected with a torque motor. The laser automatic aligning and de-weighting part comprises a positioned light source, a de-weighting machining light source and a position sensitive device. A balance weight disc is installed at the tail end of a main shaft rotor. The unbalance detecting part comprises an acceleration sensor, a displacement sensor, a phase demodulation sensor and an industrial computer for computing the unbalance amount. Compared with a traditional dynamic balancing device, the high-speed main shaft complete machine intelligent dynamic balance device has the advantages that no manual interference is needed, the main shaft does not need to be detached, the rotor is driven by a matched variable-frequency device, the actual working conditions are easily simulated, and the dynamic balance accuracy and efficiency are effectively improved.

Description

technical field [0001] The invention relates to a vibration test and control system for rotating equipment, in particular to an intelligent dynamic balance device for a high-speed spindle complete machine. Background technique [0002] The modern high-speed CNC machining center has the characteristics of high spindle speed, high running precision and high processing efficiency. The improvement of high-speed spindle speed and precision is based on the premise of high-precision dynamic balance. Small imbalances at high speeds can also cause severe vibrations and even lead to failure of the spindle. Whether the high-speed spindle can be dynamically balanced is not only directly related to the machining accuracy of the CNC machine tool, but also involves processing safety issues. Only by controlling the residual unbalance of the main shaft within a small range can the unbalanced vibration caused by the centrifugal force during the high-speed operation of the main shaft be contro...
