Weight, until can be static by impeller swing any position, and staff is not only needed to have higher experience using the method,
And it takes longer；So as to propose find blade center of gravity, by the center of gravity adjustable weight in blade come when realize static balance；
But the shape of various blades differs, and finds center of gravity trouble, needs largely to calculate, and static balance correction difficulty is larger.
Utility model content：
The purpose of the utility model is to solve the deficiencies of the prior art, and provides a kind of the quiet flat of rotating vane class workpiece
Weigh means for correcting, it facilitates the static balance of rotating vane class to correct, realizes the static balance of impeller.
The technology solution of the utility model is as follows：
A kind of static balance means for correcting of rotating vane class workpiece, including pivoting support, the upper end of pivoting support is hinged with
Balance crossbeam, one end of balance crossbeam are fixedly connected with scale weighing lever, and scale weighing lever is hinged with increasing away from one end of balance crossbeam
Counterweight hook is cut or polish jade with an emery wheel, increases and increasing stone roller counterweight is mounted in stone roller counterweight hook, the scale weighing lever upper sleeve has rider, and scale weighing lever leans on
The upper and lower side distribution of nearly one end for increasing stone roller counterweight hook is provided with lower block piece and upper block piece；Side of the workpiece far from balance crossbeam
Counterweight point is provided with, connector of weighing is connected on the workpiece side of the just upper and lower side of counterweight point, weigh connector and display of weighing
Title is connected, and display of weighing claims to be distributed in the upper and lower side of workpiece counterweight point.
Preferably, the pivoting support fixes on the ground, and display of weighing claims, lower block piece and upper block piece are secured within ground
On perpendicular stent or with ground on perpendicular metope.
Preferably, the display of weighing is known as aggravating display title, aggravates display and claims to be distributed in the surface of counterweight point.
Preferably, the display of weighing is known as loss of weight display title, and loss of weight display claims to be distributed in the underface of counterweight point.
The beneficial effects of the utility model are：
It is simple in structure, easy to operate, without largely calculating, can efficiently realize the static balance correction of rotating vane class,
So as to fulfill the static balance of impeller.

Specific embodiment：
Embodiment：As shown in Figure 1, a kind of static balance means for correcting of rotating vane class workpiece, including pivoting support 1, hinge
The upper end for connecing bearing 1 is hinged with balance crossbeam 2, and one end of balance crossbeam 2 is fixedly connected with scale weighing lever 3, and scale weighing lever 3 is carried on the back
One end from balance crossbeam 2 is hinged with increasing stone roller counterweight hook 4, increases and increasing stone roller counterweight 5, the mark are mounted in stone roller counterweight hook 4
3 upper sleeve of ruler weighing lever has rider 8, and upper and lower side distribution of the scale weighing lever 3 close to the one end for increasing stone roller counterweight hook 4 is provided with lower block
Part 6 and upper block piece 7；Side of the workpiece 12 far from balance crossbeam 2 is provided with counterweight point 11, the workpiece of the just upper and lower side of counterweight point 11
Connector 13 of weighing is connected on 12 sides, connector 13 of weighing claims 9 to be connected with display of weighing, and display of weighing claims 9 to be distributed in
The upper and lower side of 12 counterweight point 11 of workpiece.
Preferably, the pivoting support 1 fixes on the ground, and display of weighing claims 9, lower block piece 6 and upper block piece 7 to be fixed on
In on the perpendicular stent in ground or on the metope perpendicular with ground.
Preferably, the display 9 of weighing is referred to as to aggravate display to claim 91, aggravates display and claims 91 to be distributed in counterweight point 11
