Description
Technical field:
The utility model relates to a kind of instrument that is used for high-rating generator stator and rotor diametric clearance or inside dimension measurement.
Background technology:
At present, diametric clearance or inside dimension that certain depth is arranged for measurement, when hand even sight inconvenience touch even can't touch this measuring point, can only manage on need measuring point dimensional directions, to fill up object with feeling, as using clearance gauge measurement clearance size, take out object then, measure the size of object again, measure the size that needs the measuring point indirectly at thickness direction.Can't directly touch because of hand and sight, also just can't guarantee the correctness aspect position, direction and the thickness of object that the measuring point is filled in, thereby can't guarantee measured scale error in the error range that requires, measure very inconvenience simultaneously.
Summary of the invention:
The purpose of this utility model provides a kind ofly carries out the instrument that diametric clearance or inside dimension are measured at staff even the sight position that is beyond one's reach.
Above-mentioned purpose realizes by following technical scheme:
Generator stator-rotator measurement of air gap table, its composition comprises: the fixedly gauge head and movable gauge head, handle and the dial gauge that are contained in body front end, described main body internal fixation has rotating shaft, in the described rotating shaft lever is housed, described main body inside connecting rod structure, described bar linkage structure is connected with described dial gauge, on the described bar linkage structure handle is housed.
Above-mentioned generator stator-rotator measurement of air gap table, described bar linkage structure (11) comprises pipe (5) and pipe (12), push rod (4) is housed in described pipe (12), spring (6) is housed on the described push rod (4), adapter sleeve between described pipe (5) and the described pipe (12).
This technical scheme has following beneficial effect:
1. the utility model can overcome measurement under the certain depth situation, diametric clearance that hand and sight can't touch or the inconvenience on the inside dimension and the not high problem of measuring accuracy.
2. the size that movable gauge head records is directly delivered on the dial gauge by bar linkage structure, and measurement data is directly readable, and is easy to operate, measures accurately.
Description of drawings: accompanying drawing 1 is the structural representation of this product.
Accompanying drawing 2 is structural representations of bar linkage structure.
Embodiment:
Embodiment 1:
Generator stator-rotator measurement of air gap table, its composition comprises: the fixedly gauge head 1 and movable gauge head 2, handle 7 and the dial gauge 8 that are contained in main body 9 front ends, described main body 9 internal fixation have rotating shaft 10, in the described rotating shaft 10 lever 3 is housed, described main body 9 inside connecting rod structures 11, described bar linkage structure 11 is connected with described dial gauge 8, on the described bar linkage structure 11 handle 7 is housed.Described bar linkage structure 11 comprises pipe 5 and pipe 12, in described pipe 12, push rod 4 is housed, on the described push rod 4 spring 6 is housed, one end of push rod 4 is connected with lever 3, the other end is connected with dial gauge 8, the other end of lever 3 is connected with movable gauge head 2, and adapter sleeve 13 and adapter sleeve 14 are housed between described pipe 5 and the described pipe 12.
Above-mentioned generator stator-rotator measurement of air gap table, during work, fixedly gauge head 1 and movable gauge head 2 are insinuated into and need sites measured, fixing gauge head 1 is propped up a side that needs the measuring point, and movable gauge head 2 will be because of ejecting the opposite side that props up the need measuring point, turning handle 7 automatically under the effect of pipe 5 inner springs 6, then movable gauge head 2 stretches and displacement (size) variation of generation, be delivered on the dial gauge 8 by lever 3 and push rod 4, directly read measurement data, thereby reach the measurement purpose.
Above-mentioned generator stator-rotator measurement of air gap table, during installation:
1, the clamping of diametric clearance dial gauge and to zero
Clean the Lower shaft sleeve sassafras of dial gauge, put into carefully in the straight tube of dial framework.And after the owner pointer that makes table turns at least one circle, with the fastening clip of clamping lever, clamping force should not be too big, nominal clearance size according to tested radius, the fixedly gauge head of choosing a corresponding size is screwed on the main body, according to the basic size of tested radius nominal clearance, adjusts fixedly gauge head, make its size be slightly larger than nominal size+tolerance/2, and fastening with nut.Choose the suitable outside micrometer of measurement range (measurement range is 25mm～50mm or 50mm～75mm or 75mm～100mm), with staple or soft cloth two measurement faces of outside micrometer, fixedly gauge head, movable gauge head are cleaned.With several down movable gauge heads of hand, the dial gauge pen travel should be steadily, flexible, no catching phenomenon.Then to zero, the movable gauge head of a hand, one holds handle, gauge head is contacted with two measurement faces of outside micrometer, and make that fixedly gauge head is motionless, swings dial framework all around, and the least count of finding out table is " flex point ".Rotate the index dial of dial gauge, make " flex point " of zero line and pointer locate to coincide, after good zero-bit, the diametric clearance dial gauge is taken out in milscale.
2, measuring method
Diametric clearance dial gauge to after the good zero-bit must not become flexible its clamping lever, in case zero-bit changes.During measurement, one holds the upper end handle, another hand movable gauge head of end of staying, an angle tilts, gauge head is carefully put into measured workpiece diametric clearance slotted eye, when being the radius clearance of 70mm as the measurement clearance nominal size, milscale fixed be 70mm, unclamp the fixedly check nut of gauge head of clearance measurement table then, straight pin is inserted in the circular hole of fixing gauge head, regulate the degree of depth that is screwed into of its screw thread, guarantee that under free state fixedly the bulb limit actual range size of gauge head and movable gauge head axis direction is suitable, fastening afterwards check nut, fixedly gauge head contacts with two measurement faces of milscale with the sphere of movable gauge head then, adjusts the dial gauge index dial simultaneously, is guaranteeing under the situation that fixedly gauge head and movable gauge head axis direction are vertical with miking face (promptly fixedly gauge head and movable gauge head axis direction bulb limit actual range are of a size of minimum), make " flex point " of dial gauge zero line and pointer locate to coincide, to good zero-bit.
Gripping handle probes into the detection position that needs to detect workpiece with the probe part of diametric clearance meter then, care should be used to is avoided colliding with when probeing into, after making fixedly gauge head and movable gauge head and the detection position of workpiece closely contact, swing dial framework all around, the least count of all finding out dial gauge in axial plane, sagittal plane is " flex point ".The reading value of this point is exactly the poor of measured gap size and mike, is the deviate that detects nominal size.In order to measure the offset of motor stator and rotor, can measure on 4 positions of 90 ° of distributions in same sagittal plane, 2 angles differ half i.e. eccentricity value of direction stator and rotor for this reason of difference of the value of least count separately of the dial gauge of 180 ° of positions.
Clockwise or counterclockwise turn clamping lever can make dial gauge locking or unclamps.Rotate the index dial of dial gauge, can adjust the sensing position of dial gauge pointer.
