Abstract
The utility model provides a turbine rotor pressing end face measuring block pair which can determine whether the height from a grinded turbine rotor pressing end face to a turbine head back side step is accurate with the advantages of labor saving and time saving, high accuracy, and high working efficiency. The turbine rotor pressing end face measuring block pair comprises a pair of measuring blocks; wherein installing surfaces of the measuring blocks are pieced with each other; the measuring blocks comprise a go gauge block and a no-go gauge block; bottom end faces of the go gauge block and the no-go gauge block which are pieced with each other are parallel and level with each other and are attached to the turbine head back side step, head end faces of the go gauge block and the no-go gauge block are both planes; the shortest distance from the head end face to the bottom end face of the go gauge block is D-d, the shortest distance from the head end face to the bottom end face of the no-go gauge block is D+d; and the turbine rotor is sleeved in a cavity formed by the go gauge block and the no-go gauge block which are pieced with each other.
Description
Technical field
The utility model relates to the technical field that turbine is made, and is specially a kind of turbine rotor and presses end surface measurement to piece.
Background technology
In the turbine rotor process, there is one technology to press end face for the mill turbine rotor.Technological requirement is slightly finish grinded turbine rotor and is pressed tip-to-face distance turbine head back side bench height D ± d (unit of saving here), because machining precision is than higher, and the difficult measurement in step position, waste time and energy during measurement, and error is big, inefficiency.
Summary of the invention
To the problems referred to above, the utility model provides a kind of turbine rotor to press end surface measurement to piece, and it makes judges that whether accurately time saving and energy saving the mill turbine rotor press tip-to-face distance turbine head back side bench height and degree of accuracy high, high efficiency.
A kind of turbine rotor presses end surface measurement to piece; Its technical scheme is such: it comprises a pair of measurement block; The mutual amalgamation of the installed surface of said measurement block is characterized in that: said measurement block comprises drift piece, no-go gage piece, the said drift piece after the amalgamation, the bottom face flush of no-go gage piece and the turbine head back side step of fitting; The head end of said drift piece, no-go gage piece is for being the plane; The head end of said drift piece is D-d to the bee-line of its bottom face, and the head end of said no-go gage piece is D+d to the bee-line of its bottom face, and turbine rotor is set in said drift piece after the mutual amalgamation, the formed cavity of no-go gage piece.
After adopting the structure of the utility model; After having ground turbine rotor pressure end face; With the bottom face of drift piece, the no-go gage piece turbine head back side step of fitting respectively; And the installed surface of amalgamation drift piece, no-go gage piece, observe turbine rotor afterwards and press end face whether between the head end of the head end of drift piece, no-go gage piece or concordant, if turbine rotor presses end face between the head end of the head end of drift piece, no-go gage piece or concordant then judge that the position is qualified; Otherwise judge that the position is defective, it makes judges that whether accurately time saving and energy saving the mill turbine rotor press tip-to-face distance turbine head back side bench height and degree of accuracy high, high efficiency.
