[specific embodiment]
Referring to accompanying drawing 2, the utility model has adopted a kind of compound main shaft system precision dynamic checkout gear, and described checkout gear comprises bracing or strutting arrangement, base 28, frame of reference 21, and wherein, base 28 is reference for installation; It is characterized in that: described bracing or strutting arrangement comprises transition bracing or strutting arrangement a25, transition bracing or strutting arrangement b26, and checkout gear comprises tourelle a24, tourelle b27.
As shown in Figure 3: wherein, tourelle b comprises roller 33, supporter 31, axle 32, bearing 34, overlap 35, gland 36; Roller 33 working faces are spherical, with axle 32, for little, coordinate, and bearing 34 is arranged on supporter 31, and by gland 36, overlap 35 limited rollers 33, every end work installing positions of bearings of tested main shaft 23 is exactly tested main shaft 23 and the contact point of roller 33.Tested main shaft 23 and roller contacts for face among a small circle, and the rolling vestige is extremely narrow cylinder among a small circle, have realized that the duty of tested main shaft 23 is simulated.
Tested main shaft 23 steadily supports on two rollers 33, and this structure makes the rotational stability of tested main shaft 23, security obtain Reliable guarantee.
Tested main shaft 23 is very little with roller 33 surface roughness values.When hanging tested main shaft 23, usually use driving, when tested main shaft 23 approaches with roller 33, necessary frequent crawl driving, finally make tested main shaft 23 clash into and contact with roller 33.This shock is harmful to, and tested main shaft 23 and roller 33 surfaces are all produced to damage in various degree, directly affects roller 33 device precision simultaneously.
As shown in Figure 4: left slider 51, right slide block 49 can slide on base 28 guide rails, the left slider 51 left nuts 53 in place and the left screw mandrel 52 screwed thereof are all left hand thread, the right screw mandrel 43 of the other end and right nut 47 are all right-handed threads, rotate left screw mandrel 52 and can make left slider 51, right slide block 49 separately or approach.L is ram travel.
While hanging tested main shaft 23, can make in advance left slider 51, right slide block 49 shift near, tested main shaft 23 falls fabroil lining a48 and the fabroil lining b50 on first contact and this support V-arrangement face, shake gently clockwise again handwheel 44, make left slider 51, right slide block 49 separately, tested main shaft 23 descends until contact gently with roller 71, thereby thoroughly eliminates shock.Like this, effectively protect the surface quality of tested main shaft 23 and roller 71, protected the precision of roller devices simultaneously.
Hang while rising tested main shaft 23; can be rotated counterclockwise two handwheels 44 simultaneously; make tested main shaft 23 and roller 71 safe escape lentamente gently; the tested main shaft 23 of fully having avoided so again the imbalance because lifting to cause slides with single contact point of roller 71, has again effectively protected the surface of tested main shaft 23 and roller 71.
As shown in Figure 5: frame of reference: two torsion spring tables 61,62 according to tested main shaft 23 two on vertical direction with the combination table bar, be arranged on instrument base, mounting points place table bar can move up and down, left-right rotation, so that adjust freely, and can lock.
The bearing 34 of tourelle 24,27 must be through screening, be controlled at≤2 μ m of runout error, conformity error :≤1 μ m.And collocation evenly, sign, recognize while being convenient to assemble respectively.
In roller devices 24,27, axle 32 is most criticals with the combination assembling of roller 33.After the single-piece form and position tolerance of having controlled respectively axle 32 and roller 33, dimensional tolerance, except controlling uniformity, most important is when precision is assembled, axle 32 is wanted oppositely with the high point of beating of roller 33, after the combination, runout error will subtract each other like this, (otherwise addition), as the point of the A in Fig. 6 (roller beat high point), B point (the high point of beating of axle).
When two tourelles 24,27 are installed on base 28, in order to guarantee the axiality of main center's line, tested main shaft 23 system runnings can be arranged, carry out the Circular Run-out Tolerance monitoring in tested main shaft 23 ends with amesdial, constantly finely tuned the roller devices body, until monitoring amesdial indication is in 1 μ m scope, finally two roller devices 24,27 are carried out to pin-and-hole location on base 28, firm.
After the instrument overall installation, the single roller precision of beating can reach 1~1.5 μ m, through the tested main shaft 23 system loads runnings of one 2 times, after its stable accuracy, now roller 33 precision all are stabilized between 0.5~0.9 μ m, have met the single-wheel high-precision requirement of 1 μ m, and effect is fine.
Because this instrument does not have moving-member, because a little errors are bad, save seldom.Error mainly is comprised of roller 33 runout errors, torsion spring table 61,62 errors.
Figure DEST_PATH_DEST_PATH_IMAGE002
Described device can also be under the prerequisite that does not affect stability, precision, adopt the rotating mechanism of motor run, elastic rubber band transmission, realize semi-automation, frame of reference 22 can adopt high precision electro sensor image data according to the practical capacity situation, data handling system, print system can be set to office desk or electric cabinet form, make structure further compact, to be applicable to Field Force's operation.
