Description
Technical field
The utility model relates to a kind of Revolving body static balancing measurement mechanism.
Background technology
There is the object of many rotations need to do the rotary bodies such as the emery wheel of static equilibrium, particularly high-speed rotation, impeller, belt wheel.By the control to object static equilibrium value, in the time of can guaranteeing object rotation, caused vibration is in certain allowed band.
At present, measure Revolving body static balancing evener used and mainly contain beam barrel type, thimble-type, steel-ball type.Beam barrel type evener is comprised of balancing shaft and supporter, and supporter is generally two and is parallel to each other and cylindrical rod or the double inclined plane guide rail of level, can be also two pairs of round steel dishes overlapped and free to rotate.Thimble-type evener is comprised of thimble, pallet; Steel-ball type evener is comprised of steel ball, pallet.
For beam barrel type evener, during use by balancing shaft through the center pit of object, make the plane of the object vertical position of axle axis of weighing at peace.Then balancing shaft is placed on evener supporter, allows the balancing shaft that object is housed freely rotate, when object reaches equilibrium position, its barycenter is in lowest part.By the peak at object balance state, add suitable counterweight, make it all to reach balance in arbitrary position, now the quality of counterweight is exactly the intrinsic amount of unbalance of object itself.
For thimble-type evener, steel-ball type evener, as long as object is placed on pallet, the center pit of object is through the locating shaft on pallet.If mass of object is inhomogeneous, it can tilt to the direction laying particular stress on.By adding suitable counterweight at the relatively high point of vergence direction, make it balance.Weight mass is now exactly the intrinsic amount of unbalance of object itself.
Existing static equilibrium measuring method exists following shortcoming:
(1) precision is low.For the static equilibrium measuring method that adopts beam barrel type evener, its precision is subject to the impact of roughness, scale error and the alignment error of supporter, and precision generally can reach 160gmm; Be the object of diameter 200mm, it can measure minimum intrinsic amount of unbalance 1.6g, when intrinsic amount of unbalance is less than 1.6g in theory, cannot measure.Adopt the static equilibrium measuring method of thimble-type or steel-ball type static balancing device, its precision is subject to the impact of thimble, steel ball and pallet cooperation, pallet locating shaft and object center pit quality of fit, and precision is lower.Consider easy to operate, pallet locating shaft and object center pit generally adopt clearance fit, the object of the gap of 0.1mm to diameter 200mm weight 1000g, the measuring error producing under limiting case just can reach 1g, add the error that thimble, steel ball and pallet produce, more than composition error can reach 2g.
(2) can not be for the emery wheel inspection of semifinished product.Emery wheel semi-manufacture intensity is low, adopts above-mentioned two kinds of methods to detect the half-finished static equilibrium of emery wheel meeting the aperture of base substrate, edge are caused to damage, and employing is worn balancing shaft mode and even can be damaged base substrate.
(3) poor repeatability: the difference of each rigging position all can cause the variation of object static equilibrium measured value, cannot determine the unbalanced exact value of object, while particularly measuring the large emery wheel of weight, its repeatability is poorer.
(4) unbalanced value can not direct digital display, and existing method is all to add counterweight to measure imbalance, and counterweight need to repeatedly be adjusted.
(5) top formula or steel-ball type static equilibrium measuring method can only be applicable to lighter object.

For solving the problems of the technologies described above, the utility model adopts following technical scheme: Revolving body static balancing measurement mechanism, comprise horizontally disposed base plate, base plate is provided with lifting drive and positioning core axle, positioning core axle is located on the drive end of lifting drive, at least three LOAD CELLS are set on base plate, all LOAD CELLS are all positioned at take on the circle that positioning core axle is the center of circle, in all LOAD CELLS, place a circular pallet, pallet offers for by the circular hole of positioning core axle at circle centre position, pallet is horizontally disposed with and the center of gravity of pallet is positioned on the center line of positioning core axle.
Described LOAD CELLS is connected with controller by data line, and controller is connected with display screen by data line.
Adopt technique scheme, the utility model work is used step to be:
(1), arrange measurement mechanism: lifting drive and positioning core axle are set on horizontally disposed base plate, positioning core axle is located on the drive end of lifting drive, at least three LOAD CELLS are set on base plate, LOAD CELLS is connected with controller by data line, controller is connected with display screen by data line, all LOAD CELLS are all positioned at take on the circle that positioning core axle is the center of circle, in all LOAD CELLS, place a circular pallet, pallet offers for by the circular hole of positioning core axle at circle centre position, pallet is horizontally disposed with and the center of gravity of pallet is positioned on the center line of positioning core axle,
(2), rotary body is placed on pallet, positioning core axle supporting rotator be positioned the center pit of rotary body;
(3), control lifting drive and drive positioning core axle rising, positioning core axle is by rotary body jack-up, rotary body leaves pallet, makes center pit and the positioning core axle concentric of rotary body;
(4), control lifting drive and drive positioning core axle slow decreasing, rotary body is along with positioning core axle falls and by tray support, now rotary body is measured by different LOAD CELLS in disc each several part weight, and by the computational analysis of controller, rotary body amount of unbalance and uneven orientation adopt numeral or figure to show by display screen.
The utility model adopts the measuring method of sensor load-bearing, and rotary body is horizontal positioned on pallet, by endoporus self-centering, several LOAD CELLS is housed below pallet, and because emery wheel exists mass unbalance, each LOAD CELLS bearing load is different.Formula by controller calculates, and can calculate wheel unbalance amount and uneven orientation, and uses numeral or figure to show by display screen.
The utlity model has following beneficial effect:
1, directly perceived: directly to show wheel unbalance amount and orientation.
2, precision is high: because LOAD CELLS precision is very high, can measure the amount of unbalance at several grams of zero points.
