For measuring the dynamic balancing machine of rotor balancing
Technical field
The utility model relates to the precision measure device field of rotor, relates in particular to a kind of for measuring the dynamic balancing machine of rotor balancing.
Background technology
The rotor of High Rotation Speed, is used in crucial process equipment conventionally, need to possess higher machining precision.This just need to be after rotor machining completes or in the time that rotor is keeped in repair, key parameter to rotor detects, particularly, this detection comprises: (1) inspection of beating, for example probe positions on axle (is beated and checked it is to measure by contactless displacement probe, according to API670 standard, similarly rotor all need to be indicated the position for probe measurement on its axle, to facilitate in the time that reality is used, by beating of this position measurement rotor) inspection of beating, this precision of beating need to reach the rank of micron; (2) balance check, checks the quality of balance of rotor at rotor under rotation status.
Referring to Fig. 1, Fig. 2, in prior art, dynamic balancing machine comprises base 1 and the driving mechanism for driving rotor 30 to rotate, and base 1 top is provided with two rockers 2 along its length, the top of each rocker 2 is provided with roller plate 3, is provided with two rollers 301 in a side of roller plate 3.On base 1, be also provided with along its length axial limiting frame 4, for rotor 30 is carried out to axial limiting.When use, rotor 30 is placed in roller plate 3, belt 5 rotor drivens 30 that then connect by driving mechanism rotate, and measure the degree of unbalancedness of rotor 30.After measurement completes, rotor 30 is taken off from dynamic balancing machine, be positioned over and beat on test platform, by the test machine of beating, probe positions on the axle of rotor 30 10,20 is carried out to pulsation measurement, thereby determine the level of flapping of rotor 30.In prior art, why can not on dynamic balancing machine, complete the measurement of beating, because the roller being positioned in roller plate exists circle to beat and axial runout, and jerk value is conventionally more than 10 microns, therefore, if directly adopt the test machine of beating to measure beating of rotor on dynamic balancing machine, its precision is inadequate.
Utility model content
For addressing the above problem, it is a kind of for measuring the dynamic balancing machine of rotor balancing that the utility model provides, and it can be positioned over rotor in the detection platform of dynamic balancing machine, adopts the test machine of beating directly to measure the situation of beating of rotor.
For achieving the above object, of the present utility model for measuring the dynamic balancing machine of rotor balancing, comprise base and the driving mechanism for driving rotor to be detected to rotate, described base top is provided with two rockers along its length, wherein, the top of each described rocker is provided with back-up block, and described back-up block upper end offers the V-shaped groove for supporting described rotor.
Preferably, surround on two relative sidewalls of described V-shaped groove and offer respectively groove, in each described groove, be all removably provided with nylon block.
Preferably, described nylon block and described groove transition fit.
Preferably, on described base, the position near described two ends of rotor is respectively arranged with the axially movable axial limiting frame for stoping described rotor.
Of the present utility model for measuring the dynamic balancing machine of rotor balancing, adopt and replace roller plate structure of the prior art with the back-up block of V-shaped groove, because the difficulty of processing of V-shaped groove is little, precision is easy to guarantee, can meets the requirement of glitch detection standard.Therefore, can on dynamic balancing machine, directly adopt the test machine of beating to measure beating of rotor.On two relative sidewalls of V-shaped groove, offer groove and nylon block is set, in the time of contact surface abrasion, change nylon block, easy to operate.
Accompanying drawing explanation

Fig. 2 is the perspective view of rocker in Fig. 1;
Fig. 3 is of the present utility model for measuring the perspective view of dynamic balancing machine of rotor balancing;
Fig. 4 is the perspective view of rocker in Fig. 3;
Fig. 5 is the main TV structure schematic diagram of back-up block in Fig. 4.
Embodiment
Below, by reference to the accompanying drawings, structure of the present utility model and principle of work etc. are further described.
Referring to Fig. 3, of the present utility model for measuring the dynamic balancing machine of rotor balancing, comprise base 1 and the driving mechanism for driving rotor to be detected 30 to rotate, driving mechanism can be chosen as the driving mechanism that conventional dynamic balancing machine adopts, as shown in Figure 3, can rotate by carrying out rotor driven 30 by engine-driven belt gear, when use, belt 5 is overlapped to rotor 30, in the time that engine shaft rotates, can drive its rotation.
Base 1 top is provided with two rockers 2 along its length, and this rocker 2 is for supporting rotor 30, and wherein, the top of each rocker 2 is provided with back-up block 3, and back-up block 3 upper ends offer the V-shaped groove 301 for support rotor 30.Referring to Fig. 4, back-up block 3 upper ends offer V-shaped groove 301, and back-up block 3 can be fixed on rocker 2 by all multimodes of routine, afterwards, rotor 30 is placed in V-shaped groove 301.Because V-arrangement face is easy to process, its machining precision is higher, therefore, after the balance of rotor 30 being detected by dynamic balancing machine, without rotor 30 is pulled down, directly by the conventional testing apparatus of beating such as clock gauge to rotor 30 inspection of beating.
Further, as rotor 30 is directly placed in the V-shaped groove 301 of back-up block 3, so, when V-shaped groove 301 weares and teares, need by back-up block 3 integral replacings this mode, waste material and not easy to operate.For improving this situation, in the utility model, adopt in such a way, referring to Fig. 5, surround on two relative sidewalls of V-shaped groove 301 and offer respectively groove (not indicating in figure), in each groove, be all removably provided with nylon block 302.Like this, rotor 30 directly contacts with nylon block 302, rotate with respect to nylon block 302, and in the time that nylon block 302 weares and teares, dismounting and change.Particularly, this removably connects to be chosen as and is threaded and clamping etc.
In addition, nylon block 302 can be chosen as transition fit with groove, is convenient to installation and removal.
For accurately measuring the situation of beating of rotor 30, on base 1, be respectively arranged with the axially movable axial limiting frame 4 for stoping rotor 30 near the position at rotor 30 two ends.In the time that rotor 30 is positioned on back-up block 3, two axial limiting framves 4 are placed in respectively the two ends of rotor 30, limit its axial motion.According to API617 standard or API672 standard, the franchise that rotor probe positions circle is beated is 6.5 microns, and this kind of mode can meet above-mentioned standard-required.
Adopt this mode of the present utility model, can be directly on the test platform of dynamic balancing machine, adopt the test machine of beating to detect the situation of beating of rotor, improve work efficiency.
Above, be only schematic description of the present utility model, it will be recognized by those skilled in the art that and do not departing from the basis of principle of work of the present utility model, can make multiple improvement to the utility model, this all belongs to protection domain of the present utility model.
