Abstract

The invention provides an online high-precision intelligent grinding device and method for the cold welding layer of the shaft journal of a wind power generator, wherein the device includes a positioning and coupling mechanism installed on the generator shaft; An axial feed mechanism, a radial feed mechanism, a circumferential rotation mechanism, and a grinding mechanism; the grinding mechanism is used to grind the journal of the wind power generator after cold welding, so as to restore the journal of the wind power generator The original standard size; the axial feed mechanism drives the grinding mechanism to grind along the axial direction of the journal of the wind power generator; the radial feed mechanism drives the grinding mechanism to make it grind along the shaft journal of the wind power generator Grinding in the radial direction of the neck; the circumferential rotation mechanism drives the grinding mechanism to complete the circumferential grinding of the shaft by reciprocating 125° along the circumferential direction of the shaft journal of the wind power generator; the positioning joint shaft The mechanism is used to complete the coupling between the grinding equipment and the generator shaft. The device of the invention has high production efficiency, high processing precision and high economic benefit.

Description

Technical field [0001] The present invention belongs to the field of precision grinding techniques, and more particularly to a high-precision intelligent grinding repair apparatus for wind electromechanical axis-colored cold soldering layer and its method thereof. Background technique [0002] Low speed spindle, gear, and power generator are the main transmission components of wind turbines. Wind turbines work environment is relatively bad, and the wind direction and wind speed of casual changes can lead to irregular fan axis neck. The land-on wind opportunity in the frontier area is subject to dust, and sea wind turbines will be chemically corroded by salt air, thereby The surface wear of the engine rotor axis neck is relatively serious. Once the failure is invalid, the wind turbine will not work. In the past, the practice of the failure rotor shaft is to replace the new rotor shaft, and a rotor shaft manufacturing cost is 20-500,000 yuan for a large wind generator, but only bec...
