[0030] Specific implementation mode two: combination Figure 1 to Figure 6 Describe the present embodiment. In this embodiment, a method of processing the installation hole of the steam turbine high and medium pressure rotor regulating stage installation hole processing and positioning device is adopted. steps are achieved,
[0031] Step 1. Draw a line:
[0032] Mark the mounting holes to be processed on both sides of the fork-type impeller of the rotor 6;
[0033] Step 2. Positioning the blade 5 and the rotor 6 by using the installation hole processing and positioning device of the high and medium pressure rotor regulating stage of the steam turbine:
[0034]The fork-type blade root of the blade 5 is inserted on the fork-type impeller of the rotor 6, and the fork-type blade root of the blade 5 and the fork-type impeller of the rotor 6 have a slight interference fit, and the groove of the positioning frame 1 is buckled on the rotor 6 On the fork-type impeller, the left posi...

[0043] Specific implementation mode three: combination Figure 1 to Figure 6 To illustrate this embodiment, the length of the keyway milling cutter described in Step 3 of this embodiment is 50 mm, and the depth of the positioning hole for milling processing described in Step 3 is 20 mm. In this way, in this embodiment, two Φ10mm first positioning sleeves are inserted into the first positioning hole 1-1-1 of the left positioning plate 1-1 to ensure accurate positioning of the keyway milling cutter. In order to prevent the two-way drilling from being out of concentricity caused by the deviation of the drill bit when drilling, first connect the keyway milling cutter with a length of 50mm to the machine tool by using the conversion tool holder, and use the keyway milling cutter to process the positioning hole with a depth of 20mm, because the keyway cutter is positioned accurately to ensure that it is perpendicular to the workpiece Spend. Other compositions and connections are th...
