Abstract
The invention provides a steam turbine square steel blade fixture which fixes conveniently and saves materials in processing and is jointed on a driving fixture and a followed thimble on a milling machine by a blade shroud tailstock barrel and a blade root fixture. The rotation center of the blade shroud tailstock barrel and the blade root fixture coincides with the rotation center of the blade. The inner cavities of the blade shroud tailstock barrel and a blade root fixture are the modeling structures of the blade shroud and blade root of the blade. Through fixing the blade by the blade shroud tailstock barrel and the blade root fixture whose centers coincide with the rotation center of the blade, the rotation center of the blade and the milling machine are coincided highly and the processing precision is improved. The fixture does not need drilling the centre holes at two sides of the blade, thus decreasing the procedures and improving the production efficiency.
Description
Technical field
The present invention relates to a kind of anchor clamps, particularly a kind of steam turbine square steel blade fixture that clamps conveniently and add the material-saving in man-hour.
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.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of steam turbine square steel blade fixture that clamps conveniently and add the material-saving in man-hour.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of steam turbine square steel blade fixture is made of integral shroud tailstock barrel and blade root anchor clamps; Its innovative point is: described integral shroud tailstock barrel is made of fixedly connected shaped as frame connecting plate A on the integral shroud location-plate; Described blade root anchor clamps are made of fixedly connected shaped as frame connecting plate B on the blade root location-plate.
Further, constitute the integral shroud inner chamber between described shaped as frame connecting plate A and the integral shroud location-plate.
Further, have centre hole on the integral shroud location-plate of described integral shroud tailstock barrel.
Further, constitute the blade root inner chamber between described shaped as frame connecting plate B and the blade root location-plate.
Further, be connected with the round pin that cooperates with centre hole on the described blade root location-plate.
Further, symmetry has bolt hole on four angles of described shaped as frame connecting plate B.
The invention has the advantages that: adopt the integral shroud tailstock barrel and the blade root anchor clamps that overlap with the blade centre of gyration to fix blade, 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, reduce operation, improved production efficiency.
Description of drawings
Figure is the structural representation of steam turbine square steel blade fixture of the present invention.
The specific embodiment
As shown in the figure, a kind of steam turbine square steel blade fixture of the present invention is made of integral shroud tailstock barrel 1 and blade root anchor clamps 2.Wherein, integral shroud tailstock barrel 1 is made of with the integral shroud location-plate 6 that is fixed on shaped as frame connecting plate A5 end face shaped as frame connecting plate A5, and the inner chamber of shaped as frame connecting plate A5 and integral shroud location-plate 6 formations is the integral shroud imitated structure of blade; Blade root anchor clamps 2 are made of with the blade root location-plate 8 that is fixed on shaped as frame connecting plate B7 end face shaped as frame connecting plate B7, and the inner chamber of shaped as frame connecting plate B7 and blade root location-plate 8 formations is the blade root imitated structure of blade.
The high contact ratio of the blade centre of gyration and the milling machine centre of gyration when clamping for assurance, we have the centre hole 9 that overlaps with the blade centre of gyration on integral shroud location-plate 6, be connected with the round pin 10 that overlaps with the blade centre of gyration on the blade root location-plate 8, draw centre hole 9, round pin 10 and the blade centre of gyration and overlap; Wherein, 4 coaxial connections of retinue thimble of centre hole 9 and milling machine, round pin 10 and 3 coaxial connections of milling machine driving disc spacing pressing clamp body, thus realized the high contact ratio of retinue thimble 4, driving disc spacing pressing clamp body 3 and the blade centre of gyration.
During use, integral shroud tailstock barrel 1 and blade root anchor clamps 2 are enclosed within integral shroud, the blade root end of blade respectively, the centre hole 9 of integral shroud tailstock barrel 1 and the milling machine thimble 4 of accompanying is connected, and the round pin 10 of blade root anchor clamps 2 is connected with the rotating central hole of driving disc spacing pressing clamp body 3; For realizing fixedlying connected of milling machine driving disc spacing pressing clamp body 3 and blade, we have the bolt hole 11 corresponding with driving disc spacing pressing clamp body 3 screw rods at symmetry on four angles of shaped as frame connecting plate B7 of blade root anchor clamps 2, by nut blade root anchor clamps 2 are fixed on the driving disc spacing pressing clamp body 3.
