Abstract
The invention provides a novel clamping tool used for three-coordinate detection of a static blade profile, which can effectively solve the problems of complicated clamping and unstable blade positioning of the traditional detection tool and can ensure the stability of detection reference and integrity of detection information. The novel clamping tool comprises a bottom plate and is characterized in that supporting seats are arranged at two horizontal sides of the bottom plate; a double-center seat and a single-center seat are respectively arranged on the supporting seats at two sides; two moving centers are arranged on the double-center seat; and a single center is arranged on the single-center seat.
Description
Technical field
The present invention relates to blade profile testing tool field, be specially novel stator blade profile three-dimensional detection clamping tool.
Background technology
Existing stator blade profile three-dimensional test measuring device, it is located with the leading edge fillet, big small end at blade respectively is provided with a V-block support blade, be positioned over then on the three-dimensional detection platform, wherein the V-block side is provided with the magnetic device, be used to hold blade, to guarantee the stability of blade in the testing process.Reaching big end axial locating surface with three center pits when three-dimensional detects is benchmark, carries on the back each gear cross section profile degree of arc etc. in detecting.Its shortcoming is: blade profile also needs the magnetic device after being positioned on two V-blocks, its clamping complexity, and the location is stable inadequately; Set up interior back of the body directional reference with three center pits, benchmark is set up unstable; The profile zone of V-block location detect less than, can not obtain complete detection information.
Summary of the invention
At the problems referred to above, the invention provides novel stator blade profile three-dimensional detection clamping tool, it can effectively solve existing test measuring device clamping complexity, blade location problem of unstable, and can guarantee the stability of detection reference and detect information integrity.
Its technical scheme is such, it comprises base plate, it is characterized in that: described base plate both lateral sides is equipped with supporting base, be separately installed with two dead heads and single dead head on the described two-side supporting seat, two rolling centers are installed on the described pair of dead head, and it is top that a list is installed on described single dead head.
It is further characterized in that: described two rolling centers are along vertically being installed on the described pair of dead head; Described rolling center is installed on respectively in the cross through hole of described pair of dead head; Pad is equipped with lining between described rolling center and the described cross through hole; Described rolling center outside is equipped with spring; Described rolling center afterbody holds out against by screw; Described screw thread is installed on cover plate, and described cover plate is installed on described cross through hole outside; Described screw outer end is equipped with handle; Described base plate is horizontally arranged with keyway, and described two supporting bases are flush-mounted in the described keyway and pass through T type bolt; Distance and stator blade three center pit Distance Matching between described two rolling centers, the single top three.
Said structure of the present invention, it matches with three center pits of stator blade by three top tip structures, makes the blade clamping stable, reliable; And its top diameter according to location three center pits promptly can obtain in the blade benchmark that back of the body direction detects easily, and blade profile is not subjected to the position influence of Finial device, can obtain complete detection information.
