Preferably, described location block piece comprises a packing ring and adjusting bolt, and described adjusting bolt links to each other with described connecting link vertically, and described packing ring places between described adjusting bolt and described connecting link, end play when eliminating the location by this adjusting bolt improves measuring accuracy.
Preferably, be arranged with an axle sleeve on the described end face bearing outside surface.
Preferably, described sleeve interior surface is provided with oil storage tank.
As mentioned above, hi-Fix bearing dish of the present utility model has following beneficial effect:
(1) employing sleeve and the production of connecting link match grinding consist of the structure of clearance fit, and sleeve and positioning seat closely cooperate, and can prevent like this diameter run-out;
(2) adopt the end face bearing to prevent the positioning seat axial float, the rotation of end face bearing can be offset tailstock to the axial clamping force of positioning seat, makes out star wheel flexible rotating to be measured;
(3) by in the integrated end face of small space and the method for duplex bearing radially, the right alignment of positioning seat and sounding rod self is about Φ 0.005, and its structure presents rigidity and flexible flexible design, can better satisfy the precision measurement requirement of constant speed fixed knot out star wheel;
(4) difficult problem is measured in the precision positioning that has solved preferably constant speed fixed knot out star wheel, can be smart, accurate, fast clamping out star wheel to be measured, can flexible rotating again can precision positioning, the utlity model has widely, utility model is worth.

Embodiment
Below by particular specific embodiment embodiment of the present utility model is described, person skilled in the art scholar can understand other advantages of the present utility model and effect easily by the disclosed content of this instructions.
See also Fig. 1.Notice, the appended graphic structure that illustrates of this instructions, ratio, size etc., equal contents in order to cooperate instructions to disclose only, understand and reading for person skilled in the art scholar, be not to limit the enforceable qualifications of the utility model, so technical essential meaning of tool not, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under the effect that the utility model can produce and the purpose that can reach, all should still drop on the technology contents that the utility model discloses and get in the scope that can contain.Simultaneously, quote in this instructions as " on ", D score, " left side ", " right side ", " centre " reach the term of " " etc., also only for ease of understanding of narrating, but not in order to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, under without essence change technology contents, when also being considered as the enforceable category of the utility model.
As shown in Figure 1, the utility model provides a kind of hi-Fix bearing dish, be used for the location survey out star wheel, it comprises: sounding rod, end face bearing 7, sleeve 3 and the fixing positioning seat 4 used of out star wheel, sounding rod comprises sounding rod body 1 and from the outside axially extended connecting link 8 of sounding rod body one end, connecting link 8 is thinner than sounding rod body 1, end face bearing 7, sleeve 3 is located on the connecting link 8 successively, and sleeve 3 is positioned at outermost and connecting link 8 clearance fit, positioning seat 4 closely is set on the sleeve 3, connects the location block piece of a backstop positioning seat axial float at the end of connecting link 8.The utility model adopts the structure of sleeve and connecting link match grinding production formation clearance fit, and sleeve and positioning seat closely cooperate, and can prevent like this diameter run-out; Adopt the end face bearing to prevent the positioning seat axial float, the rotation of end face bearing can be offset tailstock to the axial clamping force of positioning seat, even larger axial clamping force is arranged because the existence of end face bearing is arranged, also can make positioning seat and out star wheel flexible rotating to be measured.The utility model can be smart, accurate, fast clamping out star wheel to be measured, can flexible rotating again can precision positioning.
