Abstract
The utility model relates to a steam turbine stator blade three-thimble clamping milling fixture, which is characterized by comprising a fixture body, a movable thimble and a fixed thimble, wherein two parallel through holes are drilled in the fixture body, the fixed thimble is mounted in on through hole, the movable thimble is mounted in the other through hole, the movable thimble is matched with the through hole in a sliding manner, the tail end of the movable thimble is provided with a slope, the guide parts of the fixed thimble and movable thimble are processed to be truncated cone-shaped, the fixture body is connected with an adjusting bolt in a threaded manner, the end part of the screw body of the adjusting bolt is set to be a taper matched with the slope. The guide parts of the fixed thimble and movable thimble are processed to be truncated cone-shaped, and the guide part of a center drill is also grinded to be truncated cone-shaped, so that the thimble hole depth of a blade workpiece is reduced; by adjusting the cooperation between the taper on the adjusting bolt and the slope of the movable thimble, the movable thimble is pushed to move forwards to ensure the positioning accuracy in clamping, so that the processing accuracy of the blade is ensured.
Description
Technical field
The utility model relates to a kind of turbine Blade Machining fixture, particularly a kind of steam turbine stator blade three thimble clamping milling clampers.
Background technology
258-5 level steam turbine stator blade is in process, and it adopts rectangle material to carry out line cutting special-shaped face, and because blade itself is longer, line cutting is very time-consuming, and production efficiency is low; And employing additive method, because the surplus of blank is less, it has only grown 10mm compared to finished product; Allowance is too low, cannot adopt traditional frock clamping to carry out numerical control mill.Therefore imperative for the little a kind of new turbine Blade Machining fixture of blade blank research and development of allowance.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of little surplus blank clamping and high steam turbine stator blade three thimble clamping milling clampers of machining accuracy of being applicable to.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of steam turbine stator blade three thimble clamping milling clampers, its innovative point is: comprise clamp body, movable thimble and fixing thimble, clamp body is a rectangular metal body, the centre drill CNC milling machine of clamp body is fixing with locating hole, bores the parallel and symmetrically arranged through hole of twice in the clamp body of locating hole both sides; The dual-side of clamp body arranges CNC milling machine rotary disk clamping groove; Fixedly thimble, is placed in a through hole of clamp body, and is connected and fixed with clamp body; Movable thimble, is placed in another through hole of clamp body, and is slidably matched with through hole, at the end of movable thimble, has an inclined-plane; The targeting part of described fixedly thimble and movable thimble is processed into round table-like; Adjust bolt, be drilled with screwed hole vertical with the through hole that movable thimble is installed and that be communicated with on clamp body, adjust bolt and be threaded on clamp body by this screwed hole, the taper matching with surface slope is arranged in the end of its screw rod body.
Further, the angle of described inclined-plane and through-bore axis is 70 °; The conehead tapering of described adjustment bolt is 40 °.
The utility model has the advantage of: by the fixing targeting part of thimble and movable thimble is processed into round table-like, and centre drill targeting part is also worn into truncated cone-shaped, the centre hole 4-5mm that truncated cone-shaped embeds blank can locate, and then realize three thimble clamping blade blanks, reduce the degree of depth of centre hole; For fixedly thimble and movable thimble end, because the centre hole degree of depth of this side of blank can not be equally dark, therefore, this fixture also can coordinate by adjusting the taper of bolt and the inclined-plane of movable thimble, promotion movable thimble moves forward, guarantee clamping positioning precision, the machining accuracy of blade is protected.

The specific embodiment
Embodiment
Refer to Fig. 1,2, the utility model has disclosed a kind of steam turbine stator blade three thimble clamping milling clamper structures,
Comprise clamp body 1, movable thimble 2, fixing thimble 3 and adjust bolt 4.
Clamp body 1 is a rectangular metal body, its long 170mm, wide 60mm, thick 49mm.At the fixing locating hole 5 of using of centre drill CNC milling machine of clamp body 1, the aperture of locating hole 5 is 5mm, bores the parallel and symmetrically arranged through hole 6 of twice in the clamp body of locating hole 5 both sides, and the aperture of through hole 6 is 12mm.The dual-side of clamp body 1 arranges CNC milling machine rotary disk clamping groove 7.
Fixedly thimble 3, are placed in a wherein through hole of clamp body 1, and are connected and fixed with clamp body 1.
Movable thimble 2, is placed in another through hole of clamp body 1, and is slidably matched with through hole, at the end of movable thimble 2, has an inclined-plane; The angle of this inclined-plane and through-bore axis is 70 °.Fixedly the targeting part of thimble 3 and movable thimble 2 is processed to prune top round table-like.
Adjust bolt 4, be drilled with screwed hole vertical with the through hole that movable thimble 2 is installed and that be communicated with on clamp body 1, adjust bolt 4 and be threaded on clamp body 1 by this screwed hole, the taper matching with surface slope is arranged in the end of its screw rod body.In the present embodiment, the conehead tapering of adjusting bolt is 40 °.
