Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
As shown in Figure 1, 2, a kind of axial workpiece coaxality measuring mechanism, including upper cover plate 1, handle 2, cushion block 3, pressure
Spring 4, the first screw rod 5, sliding block cushion block 6, side cover plate 7, slider bottom plate 8, positioning plate 9, bushing 10, first reducing motors 11, bottom
Plate 12, second reducing motors 13, fixed plate 14, idler wheel 15, amesdial 16, bracket 17, small axis 18, the second screw rod 19, glue coating wheel
Component 20 and sliding block pressing plate 21；
It is equipped with side cover plate 7 in 1 side of upper cover plate, outside is equipped with cushion block 3；Handle 2 is set on cushion block 3 by straight pin；
Compression spring 4 is sheathed on the first screw rod 5, and the first screw rod 5 passes through side cover plate 7 and is set in sliding block cushion block 6；It is equipped with above bottom plate 12
Second reducing motors 13 and positioning plate 9；Positioning plate 9 is equipped with first reducing motors 11；Sliding block pressing plate 21 is set under upper cover plate 1
Side；Second screw rod 19 passes through sliding block pressing plate 21, encapsulated wheel assembly 20 and slider bottom plate 8, by the tooth for being set to 19 bottom of the second screw rod
It takes turns and is engaged with the gear for being set to 11 top of first reducing motors；Small axis 18 is equipped with idler wheel 15, and small 18 bottom of axis is equipped with gear,

Two worm speed-down motors have been used to drive core bar rotation in the utility model, operator need to only execute clamping behaviour
Make, greatly reduces detection workload.Bilateral has driving force to solve the problems, such as that commercial weight tool transmission is hypodynamic.
The utility model substitutes original black rubber using polyurethane material, and it is insufficient to solve the perishable frictional force of former rubber
Problem.Polyurethane material is a kind of novel high polymer material between rubber and plastics., intensity wide with hardness range
The characteristics such as high, wear-resisting, oil resistant, resistance to oxidation, and shock-absorbing, cushion performance are excellent；The transmission mode of motor rotation eliminates to be turned by hand
Dynamic operation, and revolving speed steadily not only increases detection efficiency and also improves measurement accuracy；It is removed additionally, due to hand-turning idler wheel
Radial rotary power inevitably in the presence of axial thrust and then influences measurement accuracy, and this problem has been solved perfectly in motor drive.
The utility model has carried out standard rod and core bar two parts test in kind after the assembly is completed:
Standard rod is that centreless grinding processes 2,5 stainless steel polished rod of Φ (miking diameter difference is within 0.005), real
Object core bar chooses MZJ-200A core bar 3000.
Test result is as follows:
A. it is respectively 0.005 and 0.01 that standard rod, which carries out 2 jerk values when bounce test, and jerk value is respectively less than 0.02, because
Device stable structure jerk value itself just sentences measuring tool qualification not because part category is related to quantity.Then enter in kind
Detection-phase；
B. trial period test is carried out in processing subsidiary factory modeling pincers group, has chosen one batch of MZJ-200A core bar totally 3000
Part.It is selected through the measuring device, picks out the unqualified core bar of more than 300 parts bounce altogether.The part unqualified core bar of bounce is transferred to
Turner is corrected process.
A, the soft pawl bounce of turner correcting process surveys 0.01, is detected after the clamping overproof core bar of part jerk value with amesdial
(detection before correction) jerk value is more than 0.05；
B, 20 are chosen in the core bar for detecting jerk value qualification before detect jerk value with amesdial on same lathe
Within 0.06.
By qualified product and the dual test of rejected product, it is qualified that this measuring tool distinguishing ability is verified again.
In core bar test job in kind, after actual measurement this batch core bar detection work compared with old detection instrument efficiency improve to
It is one times few.
