Embodiment Construction
[0008] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0009] figure 1 An embodiment of the present invention is given, and it can be seen from the accompanying drawings that the present invention relates to a method for detecting the coaxiality of a stator bracket of a wind power generator and a tooling;
[0010] The detection method is to use a dial indicator to detect the coaxiality of the stator bracket of the wind power generator, install a measuring seat main body 1 matching the central mounting hole of the stator bracket on the central mounting hole of the stator bracket, 1. A rotatable measuring arm 3 is installed. The measuring arm 3 is inserted with a measuring rod 5 against the outer circle of the stator bracket. The dial indicator 7 is used to detect the coaxiality of the wind turbine stator bracket.
[0011] The coaxiality detection tool for the stator bracket of the wind power generator prop...

The invention relates to a method and device for detecting the axiality of a stator bracket of a wind generator. In the invention, dial gauges are used for detecting the axiality of a stator bracket of a wind generator; a measuring seat main body is arranged on and matched with a center mounting hole of the stator bracket; the measuring seat main body is provided with a rotatable measuring arm; a measuring rod is inserted in the measuring arm in a position close to the excircle of the stator bracket; and the dial gauges are distributed on the measuring rod up and down and can detect the axiality of the stator bracket of the wind generator by rotating the measuring arm. The measuring seat main body comprises a positioning flange and a measuring seat sleeve, wherein the positioning flange is connected with the measuring seat sleeve into a whole by a reinforcing rib; a rotating shaft is embedded in a centerline position of the measuring seat sleeve of the measuring seat main body, and both ends of the rotating shaft are provided with a tapered roller bearing; the top of the rotating shaft is connected with the measuring arm, the upper end of the measuring arm is fixedly provided with a counterweight reinforcing rib, and the tail end of the measuring arm is fixedly provided with the measuring rod; and the measuring rod is provided with three dial gauges.
Description
technical field [0001] The invention relates to a detection method and device of a wind power generator, in particular to a detection method and device of a wind power generator coaxiality, which can effectively measure the coaxiality of a wind power generator stator support. Background technique [0002] At present, the megawatt-level wind power generator is an advanced technology imported from abroad by our country, and this is a green and environmentally friendly project, which is the trend of the future. The main product produced by the Wind Power Branch of the Motor Company is the stator of the 1.5MW permanent magnet direct drive wind turbine, and the stator core is made of fan-shaped punched sheets. In order to ensure the integrity of the stacked stack, the quality control of the stator bracket is easy. It seems very important. However, the stator bracket of a large motor is a huge object. The existing inspection tooling is more difficult to detect and control many sp...
