Abstract
The invention relates to a turning auxiliary clamping device, in particular to a turbine rotor turning auxiliary clamping device with a function of spigot positioning, and aims to solve the problems that a part of an electric terminal to be clamped cannot be machined during turbine rotor turning, and the flange excircle wall which is thin is easy to deform and affects beating. The turbine rotor turning auxiliary clamping device comprises a cylinder, the center of the upper surface of the cylinder is provided with a round boss, the outer side wall of the cylinder is provided with a threaded hole, and the upper surface of the cylinder is round and is provided with eight through holes. The turbine rotor turning auxiliary clamping device is applied in turbine rotor turning.
Description
Technical field
The present invention relates to a kind of turning processing auxiliary clamping device, be specifically related to a kind of turbine rotor turning processing auxiliary clamping device that utilizes the seam location.
Background technology
Add man-hour in the turning of high pressure rotor, because the high pressure rotor adjusts end there is no flange (just optical axis) because diameter is little, can't clamp by sleeping car chuck, so can only clamp other positions of electric end flanges processing rotor, electric end is stepped up position (electric end flanges cylindrical, end face etc.) by the sleeping carriage chuck can't be processed, and the flange excircle wall is thin, yielding, impact is beated.
Summary of the invention
The present invention is for solving in turbine rotor turning processing, and the clamped position of electricity end can't process, and the problem that the flange excircle wall is thin, yielding, impact is beated, and then proposes a kind of turbine rotor turning processing auxiliary clamping device that utilizes the seam location.
The present invention addresses the above problem the technical scheme of taking to be: the present invention includes cylinder, the middle part of cylinder upper surface is provided with round boss, on cylindrical lateral wall, has screwed hole, and the cylinder upper surface is rounded is provided with eight through holes.
The invention has the beneficial effects as follows: the present invention holds the seam location by electricity and is connected with high pressure rotor electricity end flanges, has eliminated the radial clamping power to rotor flange, and has reserved processing space, has solved the yielding difficult problem of the difficult processing in this position; The invention solves in the turning of high pressure rotor and add man-hour, because the high pressure rotor adjusts end there is no flange (just optical axis) because diameter is little, can't clamp by sleeping car chuck, so can only press from both sides other positions of electric end flanges processing rotor, electric end is stepped up position (electric end flanges cylindrical, end face etc.) by the sleeping carriage chuck can't be processed, and the flange excircle wall is thin, the difficult problem yielding, that impact is beated.
