Specific embodiment
Now in conjunction with Figure of description, specific embodiment of the present utility model is described in detail:
It as shown is a kind of multistage turbine dynamic balance of impeller tooling, mandrel 1 uses Double shaft-extension structure, and middle part is detection
Ring 1d is used to install the detection device of dynamic balancing machine, and left and right ends are respectively set to left support 1a, right support 1g, left support 1a,
Right support 1g is in contact with the support wheel of dynamic balancing machine plays a supporting role respectively;It is followed successively by between detection ring 1d and left support 1a
Left mounting ring 1c, left dead ring 1b are detected and are followed successively by right mounting ring 1e, right dead ring 1f, Zuo An between ring 1d and right support 1g
Dress ring 1c, right mounting ring 1e diameter successively decrease from inside to outside respectively tapered structure, the diameter of section with detection ring 1d abutting end
It is maximum;Left coning sleeve 2, right coning sleeve 3, left coning sleeve 2, right taper is arranged in socket respectively on left mounting ring 1c, right mounting ring 1e
The hole taper of set 3 is consistent with corresponding left mounting ring 1c, the taper of right mounting ring 1e, the axial direction of left coning sleeve 2, right coning sleeve 3
Length is less than the length of corresponding left mounting ring 1c, right mounting ring 1e, and detection ring 1d both sides of the face constitute the positioning step 6 of impeller;
Left coning sleeve 2, right coning sleeve 3 are respectively used to be socketed tested impeller 8, using the open loop structure of circumferencial direction setting notch, outer circle
Size is according to the bore design for being tested impeller 8;Left dead ring 1b, right dead ring 1f outer surface helicitic texture is respectively adopted and sets
Set with the left locking nut group 4 of its threaded, right locking nut group 5, each locking nut group is respectively by two same sizes
Locking nut composition can prevent tested 8 axial play of impeller, left locking screw using two locking nuts when assembling tested impeller 8
Mother's group 4, right locking nut group 5 can be designed to same size size to improve versatility;When dynamic balancing detection is implemented, left locking
One group in nut group 4, right locking nut group 5 contacts cooperation for fixed tested impeller 8, another group of cooperation with tested impeller 8
Clump weight 7 is set, inner screw nut in locking nut group can be replaced as to clump weight 7, outboard nut is for fixing in practical application
Clump weight 7.
In above-described embodiment, left coning sleeve 2, right coning sleeve 3 are adapted to the tested impeller 8 of different model and specification, left cone
Degree set 2, right coning sleeve 3 have the notch of appropriate width in circumferencial direction, convenient and efficient can be mounted on be relatively large in diameter, weight
In heavier tested impeller 8, using coning sleeve and the consistent tapered configuration of mounting ring, when installation only need to gently push can will be stupid
The tested impeller 8 of weight is installed on the left mounting ring 1c or right mounting ring 1e of mandrel 1;The axial length of coning sleeve is slightly less than accordingly
Mounting ring, locking nut and impeller positioning step 6 contact cooperation with tested impeller 8 respectively, can effectively fix and be tested impeller 8.
When carrying out dynamic balance of impeller detection using the utility model, as shown in figure 3, tested impeller 8 is pacified by left coning sleeve 2
On left mounting ring 1c, the wheel hub of positioning step 6 and tested impeller 8 contacts cooperation, and will be tested by left locking nut group 4
Impeller 8 is fixed;It is spirally connected on right dead ring 1f and clump weight 7 is set, the inner screw nut of the right locking nut group 5 of 7 direct replacement of clump weight,
And it is fixed by the outboard nut of right locking nut group 5.
In conclusion this patent scheme is by mandrel 1 using Double shaft-extension and cone compared with existing dynamic balance of impeller tooling
Analysis of Nested Design structure is spent, makes the generally applicable same tooling of the impeller of Multiple Type specification, improves the versatility and operability of tooling,
It improves dynamic balancing working efficiency, save cost of labor, the balance quality of design can be reached so that impeller is effectively ensured, to be promoted more
The reliability of grade turbine vacuum pump.
