Detailed description of the invention five:
Unlike detailed description of the invention one, two or four, present embodiment for nuclear power low pressure rotor turning process
In anti-axle alter locking device, the dimensional tolerance of described cylindrical pins 7 isAnd between model Ф 60 to wheel bore of preboring
Cooperation there is 0.01-0.03mm gap.
Operation principle:
For 24 Ф 90 circumference of nuclear power low pressure rotor end face of flange to wheel bore, and wheel bore is existed by four circumference therein
On axis, select four to be used for anti-axle in nuclear power low pressure rotor turning process and alter locking device,
After roughing nuclear power low pressure rotor, four circumference position to wheel bore at nuclear power low pressure rotor end face of flange axis
Each one model of processing is the pin-and-hole of Φ 60, by four claws of 4.2 meters of heavy sleeping carriage floral discs from four grooves of falling T with dead in line
Middle taking-up；
First locating piece 1 of T-shaped position portion is loaded in the groove of falling T, and the first locating piece 1 is matched in clearance with the groove of falling T,
Two sides of the second locating piece 2 of T-shaped position portion and the groove width of the groove of falling T are for closely cooperating, until four described T-shaped fixed
Bit position is put in four grooves of falling T of floral disc；
