Split turbine rotor pair wheel bolt hole boring device

Abstract

The application provides a split turbine rotor pair wheel bolt hole boring device, which comprises a transmission box, a boring part, a feeding driving part, a rotating driving part and a positioning part. The boring part is arranged on the box body of the transmission box. The feeding driving part is arranged on the box body of the transmission box and is in transmission connection with the boring part to drive the boring part to stretch and retract. The rotating driving part is arranged on the box body of the transmission box and is in transmission connection with the boring part to drive the boring part to rotate on the box body. The positioning part is arranged on the box body of the transmission box and is connected with the turbine rotor pair wheel to arrange the boring part opposite to the hole to be machined. The feeding driving part can drive the boring part to stretch and retract, and the rotating driving part can drive the boring part to rotate. The feeding driving part and the rotating driving part are matched to automatically complete the cutting and feeding actions, manual judgment of the feeding depth or manual start and stop of the device is not needed, human operation errors are reduced, the operation difficulty is reduced, and the bolt hole machining consistency is ensured.
