Abstract

The utility model relates to a clamp, in particular relates to a dovetail type blade centre hole clamp and belongs to the technical field of clamps. The dovetail type blade centre hole clamp comprises a bottom plate. A locating block is fixed to the center of the bottom plate, one end of the locating block is connected with a pressing plate through a compressing screw, a pressing groove is formed between the locating block and the pressing plate, a locating pin is arranged in the center of the bottom plate, and the locating pin is arranged on the lateral side of the locating block. The dovetail type blade centre hole clamp is convenient to clamp. A tenon degree face and an air inlet edge end are utilized to locate to be identical with the locating portion in milling the molded surface. After being pressed by the pressing plate, a blade body is in a completely free state and not interfered by external force. Thus, the deformation amount in drilling a centre hole is greatly reduced, the requirement for the position degree of the centre hole is met, the requirement for the profile tolerance in milling a blade to be in a leaf shape is guaranteed, and the pass percent of products is greatly improved.

Description

Dove-tail form blade center hole fixture
Technical field
The utility model relates to a kind of fixture, and a kind of dove-tail form blade center hole fixture, belongs to clamp technology field specifically.
Background technology
Because stator blade blade profile adopts a folder one top formula milling mode, therefore need on blade tip boss, bore a centre bore for blade milling, the position degree of centre bore size directly affects the deflection of blade profile in process.Centre hole clamp in the past adopts and clamps tenon, withstands the mode of blade tip place blade profile, and the deviation owing to holding out against is larger, causes the position degree deviation of centre bore larger, and the distortion after profile milling is larger, exceeds the requirement of blade profile tolerance.The overproof fixture of position degree while therefore needing one can solve drill centers.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby provide a kind of dove-tail form blade center hole fixture, with tenon degree face and location, leading edge termination, during with milling profile, position point is consistent, and after compressing with pressing plate, blade, completely in free state, does not have the interference of external force, deflection while therefore greatly reducing drilling centre bore, meet the position degree requirement of centre bore, guaranteed the profile tolerance requirement of the leaf milling of blade, greatly improved the qualification rate of product.
The technical scheme providing according to the utility model, dove-tail form blade center hole fixture comprises base plate, it is characterized in that: base plate center stationary positioned piece, locating piece one end connects pressing plate by housing screw, between locating piece and pressing plate, forms pressing groove; Described base plate center is provided with alignment pin, and alignment pin is positioned at locating piece side.
Further, pressing groove is swallow-tail form.
Compared with the prior art the utility model has the following advantages:
The utility model is simple in structure, compact, reasonable, convenient mounting and clamping; With tenon degree face and location, leading edge termination, during with milling profile, position point is consistent, after compressing with pressing plate, blade is completely in free state, there is no the interference of external force, deflection while therefore greatly reducing drilling centre bore, meet the position degree requirement of centre bore, guaranteed the profile tolerance requirement of the leaf milling of blade, greatly improved the qualification rate of product.
Accompanying drawing explanation
Fig. 1 is the utility model front view.
Fig. 2 is the utility model top view.
Description of reference numerals: 1-base plate, 2-locating piece, 3-pressing plate, 4-alignment pin, 5-housing screw, 6-pressing groove.
The specific embodiment
The utility model is further described in connection with the embodiment in accompanying drawing below:
As shown in Figure 1 and 2, the utility model mainly comprises base plate 1, base plate 1 center stationary positioned piece 2, and locating piece 2 one end connect pressing plate 3 by housing screw 5, form the pressing groove 6 of swallow-tail form, the interior clamping blade tenon of pressing groove 6 degree face between locating piece 2 and pressing plate 3.
Described base plate 1 center is provided with alignment pin 4, and alignment pin 4 is positioned at locating piece 2 sides, by 4 pairs of leading edge terminations of alignment pin, positions.
During the utility model work, unscrew housing screw 5, blade is packed in the pressing groove 6 of swallow-tail form.Then tighten housing screw 5, degree of making face and the blade tenon location of fitting completely.Last just can drilling centre bore, because blade tip is everywhere in free state, the error producing while eliminating external force to center hole drilling so completely.
The utility model is located with tenon degree face and leading edge termination, during with milling profile, position point is consistent, after compressing with pressing plate, blade is completely in free state, there is no the interference of external force, deflection while therefore greatly reducing drilling centre bore, meet the position degree requirement of centre bore, guaranteed the profile tolerance requirement of the leaf milling of blade, greatly improved the qualification rate of product.
