Abstract
The utility model relates to a vertical-type static balance bulb positioning and adjusting device for a hydro-generator magnet yoke. The vertical-type static balance bulb positioning and adjusting device comprises a balance ball, a bulb pressing plate, a bulb fixing block, a centering plate, an adjusting screw, a thread sleeve and a fixing plate, wherein the balance ball is fixed to the bulb fixing block by the bulb pressing plate, the centering plate is pressed and installed at a tail end of the adjusting screw by the bulb fixing block according to fit dimension, and the bulb fixing block and the adjusting screw are positioned by spigots; and the adjusting screw is connected to the fixing plate after being screwed with the thread sleeve, and a static balance workpiece magnet yoke is jointed by the fixing plate through bolts and positioned by a spigot (universal for a static balance base plate). Spigots on the centering plate and the fixing plate are used for ensuring concentricity of the balancing device and the magnet yoke workpiece.
Description
Technical field
The utility model relates to the vertical static equilibrium bulb of hydrogenerator yoke positioning adjustment device.
Background technology
The rotor rim of hydrogenerator is mostly by cast form, or by the wheel hub of casting and yoke ring and disc and gusset welding forming, because more or less can having the loose of material, the reason of casting make its weight distribution inhomogeneous, the process of welding also can make it produce the deviation of weight simultaneously, and yoke is often all heavier, therefore yoke needs to do vertical static balancing test after machining, and determines its degree of unbalancedness, then by adding the method for counterweight, meets the requirement of its degree of unbalancedness.
The bulb of existing vertical static balancing device adopts spherical pieces, and its difficulty of processing is very large, often needs repeatedly to reprocess just to reach requirement; Centering plate and spherical pieces adopt bolt closing simultaneously, and locating effect is undesirable.
Summary of the invention
The purpose of this utility model is for the vertical static equilibrium of yoke provides a kind of simple in structure, and parts easy to process simple installed easy to adjustly, and has the vertical static equilibrium positioning adjustment device of yoke of certain versatility.
The technical solution of the utility model is: balanced ball adopts the GCr15 steel ball (can, by the difference of yoke weight, choose the steel ball of different-diameter) of outsourcing, has avoided the difficulty of processing of spherical pieces; After adjusting screw rod assembling centering plate and between bulb fixed block, between fixed head and yoke workpiece, with seam location, with bolt, closing, guaranteed the concentricity of this device with yoke workpiece; Adopt and adjust the height that screw rod can conveniently be adjusted balance bulb.
The beneficial effects of the utility model are: simple in structure, to install easy to adjustly, and the process of parts is convenient and simple, has improved work efficiency, has met the statically balanced requirement of rotor rim.
Accompanying drawing explanation
Fig. 1 is assembly structure schematic diagram of the present utility model.
In accompanying drawing, each component part numbers is: 1. balanced ball, and 2. bulb pressing plate, 3. screw, 4. bulb fixed block, 5. centering plate, 6. screw, 7. adjusts screw rod, 8. screw, 9. fixed head, 10. swivel nut, 11. bolts.
Embodiment
For further understanding content of the present utility model, feature and effect, contrast accompanying drawing 1 embodiment is described in detail as follows:
The utility model structure comprises: 1. balanced ball, and 2. bulb pressing plate, 3. screw, 4. bulb fixed block, 5. centering plate, 6. screw, 7. adjusts screw rod, 8. screw, 9. fixed head, 10. swivel nut, 11. bolts.Its specific implementation method is: swivel nut 10 packs fixed head 9 into, with screw 8, compress, screw in again and adjust screw rod 7, adjust the end suit centering plate 5 of screw rod 7, fixing with bulb briquetting 4, bulb briquetting 4 is located with seam with adjusting screw rod 7, and screw 6 is tight, with bulb pressing plate 2, compress balanced ball 1 again, screw 3 is tight.The endoporus of described centering plate 5 coordinates with adjustment screw rod 7, and external diameter coordinates with yoke inner hole of workpiece, and the seam of fixed head 9 also coordinates with the endoporus of yoke workpiece, has guaranteed the concentricity of this device with yoke workpiece.This device packs into after yoke inner hole of workpiece, with 11 vertical static equilibrium fabrication holes that close yoke workpiece of bolt.The balanced ball height of this device can be by the height control of yoke workpiece to applicable position.
In sum, of the present utility model simple in structure, to install easy to adjustly, the process of parts is convenient and simple, has improved work efficiency, has met the requirement of rotor rim degree of unbalancedness.
