The invention provides a gas turbine blade grinding method and an adjusting tool, wherein the method comprises the steps that: 1) grinding equipment is positioned, wherein the positioning process comprises the steps that: the adjusting tool which comprises a dial indicator and a measuring head connected with the dial indicator is prefabricated, the adjusting tool is mounted on the grinding equipment, a measuring rod of the dial indicator is vertical to the axis of a grinding wheel, in the adjustment process, the grinding equipment is moved, the measuring head makes contact with the air inlet side and the air outlet side of a blade 1 in sequence, an air inlet side data value corresponding to the air inlet side and an air outlet side data value corresponding to the air outlet side are read, and the position of the grinding equipment is adjusted according to the air outlet side data value and the air inlet side data value, fine positioning is finished until the difference value between the air outlet side data value and the air inlet side data value is within a certain range; and (2) grinding equipment is started to grind the blade. The gas turbine blade grinding device is used for solving the problem that in the prior art, existing grinding equipment cannot directly grind and process blades of a gas turbine.
Description
technical field [0001] The invention relates to the field of mechanical processing, in particular to the field of gas turbine blade processing. Background technique [0002] At present, the intermediate maintenance of gas turbines needs to replace the working rotor blades. The most important thing is to grind the replaced rotor blades in the power plant. The ground blades should meet the design requirements of the flow gap. Because each blade on the gas turbine is installed on the rotor separately, and the single blades are not connected, each blade has a certain angle, and the angle of all blades is the same, the existing grinding equipment cannot directly process these blades Grinding. [0003] Therefore, there is a need for a method that can process all blades on the rotor after precise adjustment of a single blade. [0004] Using the adjustment tool in the present invention and using the process method, the on-site grinding equipment fundamentally breaks the original g...
