Technical field
The utility model relates to a kind of cubing, is specifically related to a kind of moulding profile tolerance of a surface cubing.
Background technology
Modern society; The development of Along with computer technology; The design and the manufacturing capacity of industrial products are greatly improved; Design is gone up can (computer-aided design (CAD)-CAD) design product very irregular but of great practical value can process then in processing that (area of computer aided is processed-CAM) processed and designs desired irregular product through the sequencing of numerically-controlled machine through computing machine powerful calculating and analog capability.But on detecting, but relatively lag behind, general checkout equipment does not mostly have turning axle, can't realize detection of dynamic.
Like Fig. 1, be the guide ring of aircraft engine air intake opening shown in 2; It is the solid of revolution of a thin-walled; Inside surface 11 is forming surface, see one section circular arc of picture from axial section, but it is not one section circular arc; But the shape that a lot of section circular arcs couple together is according to the strict result calculated of aerodynamics.
It is very difficult detecting so irregular moulding profile tolerance of a surface; Because general general measurer is the profile tolerance that can't be detected as profile; Use checkout equipment (like the profile tolerance appearance) also can only detect a part; Can't detect the whole surface of revolution, and any one point goes wrong and all will influence the work efficiency of aircraft engine on the surface of revolution.
Should, the such forming surface of guide ring still has certain representativeness, and the other products except aircraft engine is used hydromechanically if desired, generally also can use the parts that similar guide ring is provided with forming surface like this.
Therefore,, can accurately detect this moulding profile tolerance of a surface if can design a kind of cubing, and simple, convenient, be of great value so.
The utility model content
To above-mentioned problem, the purpose of the utility model is to provide a kind of forming surface profile tolerance cubing, through reliable localization and pick-up unit cleverly, reaches accurate detection, purpose simple to operate.
For achieving the above object, the technical scheme of the utility model is following:
A kind of forming surface profile tolerance cubing is characterized in that, comprises base, centring ring, detection model, and the detection steel ball that matches with the detection model; Turning axle is equipped with at said base middle part, is fixed with the detection model that comprises drift and no-go gage on the said turning axle, the shape of said drift and no-go gage and said forming surface coupling; The centring ring that is used for fixing said forming surface also is housed on the said base, and the position of said centring ring and said forming surface are complementary, and said detection steel ball is made up of steel ball and handle.
Preferably, said centring ring is fixed on the base through lock-screw.
Preferably, said turning axle top is equiped with the knurled nut of said drift of locking and no-go gage.
Preferably, said drift, no-go gage are symmetrically distributed with rotating shaft axis.
Preferably, said base is provided with 2 rolling bearings that cooperate with turning axle.
Through technique scheme, the forming surface profile tolerance cubing that the utility model provides is through adorning turning axle at base; Turning axle drives drift and no-go gage; Drift and no-go gage cooperate the detection steel ball comprehensively to detect forming surface, reach accurate detection, simple, convenient purpose.

Embodiment
To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.
As shown in Figure 3, forming surface profile tolerance cubing comprises base 2, centring ring 3, drift 51 and no-go gage 52, and the detection steel ball that matches with the drift no-go gage.
Turning axle 22 is equipped with at the base middle part, is fixed with drift 51 and no-go gage 52 on the turning axle, and drift, no-go gage are symmetrically distributed with rotating shaft axis.Drift and no-go gage can rotate with axle.Drift 51, no-go gage 52 are provided with the shape that is complementary with guide ring 1 inside surface, and drift is provided with drift gap 511, and no-go gage is provided with no-go gage gap 521.
The turning axle top is equiped with knurled nut 7, can drift 51 and no-go gage 52 be pressed on the turning axle, and when rotating, it is more steady that drift 51 or no-go gage 52 change like this.
Said detection steel ball is made up of steel ball 61 and handle 62, and steel ball is a standard component, can directly buy, and can be according to the steel ball like the different size replacing different size of the forming surface of 1 type of guide ring.
More smooth and easy for the rotation that makes turning axle 22,2 rolling bearings 21 are installed on base 2, be used to cooperate turning axle.
" detecting rule " of the forming surface profile tolerance cubing that the utility model provides: in drift 51 or no-go gage 52 rotations; Steel ball 61 all can insert drift gap 511 in any position of drift 51 ends; All can not insert no-go gage gap 521 in any position of no-go gage 52 ends for qualified, otherwise be defective.
Clearer for what embodiment was explained, the testing process in the face of said cubing is described below down:
