Description
Technical field
Originally belong to calibration equipment field, and in particular to a kind of calibration equipment of swollen poor rocker.
Background technique
Turbine rotor dilatometry instrument and common vibration measuring instrument are all made of eddy current principle, and measuring device is usually by visiting
Head+fore-lying device composition, but since rotor expansion amount is much higher than big shaft vibration amount, it is more than probe measurement range, therefore rotor expansion is surveyed
Amount generallys use lever principle, exports after current vortex signal is amplified by rocker (lever principle).Conventional vibration measuring instrument
Calibration equipment can not verify swollen poor rocker (rotor expansion measuring device).
Before the appearance of this calibration equipment, the country is done for what the verification of turbine rotor expansion probe generallyd use at present
Method is realized by vernier caliper, magnet and auxiliary fixing device.Such method exists following insufficient: 1) passing through vernier calliper
Ruler carrys out moving magnet, and measurement is inaccurate.Vernier caliper measurement part inside and outside diameter is more accurate, measurement workpiece displacement error compared with
Greatly.Such as simulation magnet is displaced 5mm, vernier caliper can not accurate simulation, checking precision not can guarantee；2) due to magnet to be simulated
Displacement, it is higher that checking procedure accidentally touches magnet probability, further increases verification error, and verifies midway and cannot stop, and otherwise to weigh
Newly start to verify；3) operating environment requirements are high, can only carry out, can not be verified at the scene in laboratory；4) checking time and verification
Heavy workload.
Summary of the invention
It is an object of the invention to: there are many serious problems, first verification essence for existing rotor expansion probe verifying device
Degree not can guarantee, and error is big；Verification step is cumbersome simultaneously, and checking time and verifying work amount are big, and can not verify at the scene.Base
In this, we have manufactured and designed the calibration equipment of the swollen poor rocker of this set.
Technical scheme is as follows: a kind of calibration equipment of swollen poor rocker, including platen, the position to keep left on platen
Set installation riser, fixed mounting plate on vertical plate；Support plate A, support plate B are mounted on platen, are pacified between support plate A, support plate B
Ball screw and guide rod are filled, and ball screw passes through connecting plate by feed screw nut, and handwheel, hand are equipped on support plate A
Wheel drives ball screw rotation, and then connecting plate is driven to be moved forward and backward；
Digital scale is also installed in support plate A, the side support plate B, digital scale is fixed on platen；And measurement plate is assembled
In connecting plate side, as connecting plate is moved forward and backward.
Pass through hexagon socket cap head screw installation riser.
Pass through hexagon socket cap head screw fixed mounting plate on vertical plate.
Support plate A, support plate B are mounted on platen by hexagon socket cap head screw.
Digital scale is fixed on platen by cross recessed countersunk head sscrew.
Lower margin is connect by the screw of M24 with platen lower surface.
Remarkable result of the invention is: traditional fixation device, measuring device and measuring table three parts are unordered
Tool is upgraded and is optimized respectively, and it is original and different integrate them, develop a set of completely new integrated form verification
Device, the measuring accuracy for solving original calibration equipment is low, verification mode is cumbersome, heavy workload, can not field-checking etc.
Problems.
Detailed description of the invention
Fig. 1 is the calibration equipment schematic diagram of swollen poor rocker of the present invention；
In figure: 1 lower margin, 2 platens, 3 digital scales, 4 support plate A, 5 measurement plates, 6 handwheels, 7 ball-screws, 8 guide rods, 9
Feed screw nut, 10 connecting plates, 11 vertical plates, 12 mounting plates, 13 support plate B
Specific embodiment
A kind of calibration equipment of swollen poor rocker, including platen 2, the position to keep left on platen 2 pass through interior hexagonal cylindrical head
Screw installation riser 11 passes through hexagon socket cap head screw fixed mounting plate 12 on vertical plate 11；Support plate A4, support plate B13 are logical
It crosses hexagon socket cap head screw to be mounted on platen 2, ball screw 7 and guide rod 8 is installed between support plate A4, support plate B13,
And ball screw 7 passes through connecting plate 10 by feed screw nut 9, and handwheel 6 is equipped on support plate A4, handwheel 6 drives ball wire
Bar 7 rotates, and then connecting plate 10 is driven to be moved forward and backward.
Digital scale 3 is also installed in support plate A4, the side support plate B13, digital scale 3 is solid by cross recessed countersunk head sscrew
It is scheduled on platen 2；And in 3 position in the middle of digital scale, measurement plate 5 is installed, measurement plate 5 is assemblied in 10 side of connecting plate,
As connecting plate 10 is moved forward and backward；
Lower margin 1 is connect by the screw of M24 with 2 lower surface of platen.
When specific works, comprising the following steps:
1) (length of needs can voluntarily be intercepted according to actual installation position using the bolt of M12 × 120 and sleeve.Wherein two
The size of root sleeve is than other two short 30mm) rocker is installed, gap is adjusted to 1mm.
2) power supply and calibration equipment are connect with fore-lying device with conducting wire appropriate.
3) direct current DC "+" and calibration equipment "-" access COM, direct current DC "-" access -24V；OUT accesses calibration equipment "+".
4) rotation hand wheel 6, change displacement, make fore-lying device output be -4V when, digital display scale is set to " 0 ".
5) it is verified according to pre-designed step-length, and records output voltage.
6) data are analyzed, error is calculated.
Attention simulation on-site actual situations during the test, forward direction measurement (far from being positive) and reverse measuremenet are (close to be
Just).
