Embodiment
As shown in Figure 1, the phase place accurate positioning device that the present invention is used for dynamic balance calibration comprises magnetic support 1, support 2, dial plate 3, vertical pointer 4 and datum line 5, described support 2 is located on described magnetic support 1, described support 2 top is located at by described dial plate 3, described vertical pointer 4 is located at described dial plate 3 center, and described datum line 5 is located at described magnetic support 1 surface and is positioned at same axis with described vertical pointer 4.
Further, above-mentioned magnetic support 1 is shape of a saddle magnetic support.Shape of a saddle magnetic support can make this device reliably be positioned in the rotating shaft of rotor, facilitates the setting of this device in dynamic balance calibration operation process.
This device can implement quick position when dynamic balance calibration, Measurement accuracy phase place, as shown in Figure 2, for laser phase detector, open laser phase detector, make laser beam projects in the rotating shaft 6 of rotor, the magnetic support 1 of this device is arranged in the rotating shaft 6 of rotor, adjust this device, make the subpoint 7 of datum line 5 alignment in rotating shaft, now on dial plate 3, the reading of plumb bob needle 4 indication is exactly the relative position angle of laser phase detector relative to the upper vertical direction (absolute position zero point) of armature spindle bearing.
According to the positive negative angle definition of transient equilibrium instrument, select the reading of input plumb bob needle 4 indication be on the occasion of or negative value, the Phase Detector spatial position data input that must provide in transient equilibrium process can be provided fast, enter rotor dynamic balancing measuring and calculation process.This corresponding relation is directly perceived, accurate, objective, and location is accurate fast, rotor dynamic balancing calibration accuracy.
As shown in Figure 3 and Figure 4, in addition, in Dynamic Balance of Rotor trimming process, the phase place of this device all right accurate positioning balance test mass block and balancing weight fast, exempts the operation of rotor 360 degree of circumference labels.Position fixing process carries out balance correction to use laser phase detector to fan rotor, is arranged in the rotating shaft 6 of rotor by this device, adjusts this device by magnetic support 1, makes datum line 5 aim at the laser reflection paper 8 be attached in rotating shaft 6; Suppose that the position of draught fan impeller the most easily being installed balance test mass block and balancing weight is below draught fan impeller, if balance test mass block need be clipped in 120 degree of phasing degree, as long as then rotating shaft 6 makes the reading of plumb bob needle 4 on dial plate 3 be 180-120=60 degree, now at draught fan impeller, balance test mass block is installed bottom.If dynamic balancing measurement result of calculation is 330 degree of phasing degree, as long as then rotating shaft 6 makes the reading of plumb bob needle 4 on dial plate 3 be 180-330=-150=210 degree, now bottom equilibrate counterweight is installed at draught fan impeller.
As shown in Figure 5, draught fan impeller can be determined bottom in accordance with the following steps: be arranged in draught fan impeller 9 outer rim by this device by magnetic support 1, adjust this device, make the reading of plumb bob needle 4 on dial plate 3 be 180 degree, impeller 9 position that now datum line 5 is aimed at is impeller 9 outer rim bottom.
This device can provide directly perceived, quick, objective, location, Phase Detector locus accurately, exempts the operation of rotor 360 degree of circumference labels, greatly improves efficiency and precision that rotor dynamic balancing corrects, is especially suitable for the dynamic balance calibration of high precision rotor.
