The invention discloses an automatic acquisition device for 
stator positioning rib 
welding deformation measurement data. The automatic acquisition device comprises a probe, a probe fixing support, a 
signal acquisition device, a terminal computer, automatic 
analysis software, output equipment, an 
alarm device and monitoring supports, wherein each monitoring support is composed of a support fixing frame, a support base and a support walking mechanism and is fixed to a lower annular plate of a 
stator annular plate; the probe fixing support comprises a supporting block, an adjustable 
cushion blockand a probe frame, the supporting block is welded and fixed to the support fixing frame, the adjustable 
cushion block is installed on the supporting block, the probe frame is welded and fixed to thefront end of the adjustable 
cushion block, and the probe is fixed to the probe frame; the 
signal acquisition device and the 
alarm device are fixed on a support base and are connected with the terminalcomputer through signals; the 
signal acquisition device is connected with the probe; and the terminal computer is provided with the automatic 
analysis software. The automatic acquisition device can perform automatic measurement, automatic recording, automatic analysis and real-time alarm, and can perform real-time monitoring when a 
stator positioning rib of a hydro-generator is welded.
