Abstract
The utility model relates to a processing clamp for a steam turbine guide blade with eccentric cambered surfaces as the end surfaces of a blade shroud and a blade base. The processing clamp comprises a blade shroud thimble sleeve and a blade base clamp used in coordination with the blade shroud thimble sleeve; the guide blade is fixed through the blade shroud thimble sleeve and the blade base clamp, wherein the gyration centers of the blade shroud thimble sleeve and the blade base are coincident with the gyration centre of the guide blade and respectively coincident with the gyration centre of a thimble of a milling machine and the gyration centre of the clamp body of a driving disc, so that the gyration centre of the guide blade is enabled to be highly coincident with that of the milling machine, and the processing accuracy is improved; and by adopting the clamp, holes are not required to be drilled at the two ends of the guide blade, so that procedures are decreased, and the production efficiency is improved. Moreover, a set screw can prevent the guide blade from moving slightly during the gyration process, so that the processing accuracy is ensured.
Description
Technical field
The utility model relates to a kind of frock clamp, the steam turbine guide vane clamp for machining that particularly a kind of integral shroud blade root end face is eccentric cambered surface.
Background technology
Usually in that being carried out high accuracy, turbine blade adds man-hour, need on milling machine, to determine earlier the centre of gyration of blade, the general three thimble fixed blades of butt two thimble bizets one thimble that adopt are processed it, adopt this thimble to process centre hole at the integral shroud and the blade root end face of not moulding, again the centre hole milling is excised after the process finishing, this employing method clamps blade, the centre of gyration registration of blade and lathe is poor, machining accuracy can not get guaranteeing, increase operating procedure simultaneously, reduced production efficiency.Be the steam turbine guide vane of eccentric cambered surface producing integral shroud blade root end face particularly, because integral shroud blade root end face is eccentric cambered surface, the clamping location is trouble more, and it is particularly evident adopting this method.
The utility model content
The steam turbine guide vane clamp for machining that it is eccentric cambered surface that the technical problems to be solved in the utility model provides a kind of integral shroud blade root end face, simple in structure, convenient mounting and clamping.
For solving the problems of the technologies described above, the technical solution of the utility model is: the steam turbine guide vane clamp for machining that a kind of integral shroud blade root end face is eccentric cambered surface, comprise integral shroud tailstock barrel and blade root anchor clamps matching used with it, it is characterized in that: described integral shroud tailstock barrel is made of integral shroud framework connecting plate inwall welding integral shroud location-plate, the inner face of described integral shroud location-plate and integral shroud framework connecting plate constitute can be chimeric with integral shroud the outer arc die cavity, have the centre hole that overlaps with the guide vane centre of gyration at integral shroud location-plate center; Described blade root anchor clamps embed the blade root location-plate by blade root framework connecting plate inwall and constitute, the inner face of described blade root location-plate and blade root framework connecting plate constitute can be chimeric with blade root the inner arc die cavity, have the setting circle pin-and-hole that overlaps with the guide vane centre of gyration at blade root framework connecting plate center, blade root framework connecting plate four limit symmetries have four screw hole are installed.
Further, all be drilled with screwed hole on described integral shroud framework connecting plate and the blade root framework connecting plate, the screwed hole screw-internal thread fit has holding screw.
Advantage of the present utility model is: during installation, adopt the integral shroud tailstock barrel and the blade root anchor clamps that overlap with the guide vane centre of gyration to fix guide vane, and the centre of gyration of integral shroud tailstock barrel and blade root anchor clamps self overlaps with thimble, the driving disc spacing pressing clamp body centre of gyration of milling machine respectively, guaranteed the high contact ratio of the blade and the milling machine centre of gyration, improved the precision of processing, and adopt this anchor clamps to need not again the blade two ends and bore centre hole, reduced operation, improved production efficiency.Holding screw can prevent that micro-position from appearring in guide vane in turning course, guarantees the precision of processing.
