| description | The invention belongs to the technical field of hydropower station unit equipment installation, and provides a hydro-generator stator positioning rib accurate positioning device and method.The positioning device comprises a stator roundness measuring frame provided with a sliding bearing, the sliding bearing is provided with a rotatable measuring arm, and the measuring arm is provided with a first displacement sensor through a radial measuring support; a positioning assembly and a second displacement sensor are hinged to the radial measuring support. The positioning method comprises the following eight steps: checking, mounting the reference positioning rib, mounting the displacement sensor, acquiring radial and circumferential clearance data from the displacement sensor to the reference positioning rib, obtaining the number of steps required to be rotated by the stepping motor, temporarily fixing the positioning rib, fixing the positioning rib by spot welding, and repeating temporary fixing and spot welding |
