Moreover, described base is with the coaxial mounted mode of sleeve：Base excircle orientation seam is matched somebody with somebody with sleeve inner stopper
Close.
Moreover, the fit clearance of described sleeve diameter and floating drum outside diameter is 0.008~0.010mm.
Moreover, the seam of the gland coordinates with floating drum.
Moreover, described length sleeve is more than floating drum length, 10mm or so is respectively about up and down；Floating drum is in sleeve when press-fiting
Slide, unilateral gap is 0.004~0.005mm.
Advantages and positive effects of the present invention are：
1st, the present invention designs device because employing the double interference of long span from centering so that framework can be coaxial with floating drum
Complete to press-fit under the conditions of degree is exigent so that the problem of high-precision liquid floated gyroscope core component structure design crosses positioning obtains
To solution, inventive structure design seems largely effective.
2nd, this invention ensures that two part mating surfaces and processing essence will not be destroyed in gyroscope core component assembling process
Degree, both eliminations press-fit centering problem and bring hidden danger, can improve the reliability of gyroscope.
3rd, the double interference of gyroscope core component long span of the present invention press-fit design from centering, greatly reduce assembly difficulty,
Improve efficiency of assembling.
4th, the present invention relates to it is a kind of applied to the double interference structures of long span from centering press-loading apparatus, the present invention is a kind of right
Liquid floats inertia type instrument and keeps the double interference of core component long span from the design of centering, and effective limiting frame and floating drum are by axial direction
Radially play or crooked after power, makes centering press-fit precision and is guaranteed, and improves performance that liquid floated gyroscope uses and reliable
Property.

Embodiment
Describe embodiments of the invention in detail below in conjunction with the accompanying drawings；It should be noted that the present embodiment is narrative, no
It is limited, it is impossible to which protection scope of the present invention is limited with this.
It is a kind of applied to the double interference structures of long span from centering press-loading apparatus, including base 3, sleeve 4 and gland 5.Bottom
The function of seat is to provide the mounting platform of a benchmark, and coaxially processing one adds for inserting framework 1 in the axle center of the mounting platform
The centre bore of work benchmark cylinder, the major diameter fit precision of the internal diameter and framework machining benchmark cylinder of the centre bore is higher.Described
The external diameter of framework machining benchmark cylinder is φ 12.5mm, between the cooperation of the made centre bore in base axle center and framework machining benchmark cylinder
Gap is (0.003~0.006) mm, and mating surface is about 10mm (mating surface refers to the length of frame of reference cylinder patchhole).
One sleeve of seam upper end coaxial package of base, the internal diameter of the sleeve is engaged with the outside diameter of floating drum 2.Sleeve
The fit clearance of internal diameter and floating drum outside diameter is (0.008~0.010) mm,.BaseHole coordinates with framework determines frame
Frame center, base excircle orientation seam coordinates with sleeve inner stopper, determines that floating drum is coaxial with framework.
The lower end of sleeve coordinates with base seam is allowed to coaxial with base, hub internal bore and floating drum major diameter fit, and plays
The guiding being axially moveable and the effect from centering.Length sleeve is more than floating drum length, and 10mm or so is respectively about up and down；When press-fiting
Floating drum is slided in sleeve, unilateral gap (0.004~0.005) mm, and the effect of sleeve is guiding and positioning.The upper end of sleeve is same
Axle sleeve fills a gland, and seam and the floating drum of the gland coordinate, the double interference self-aligning devices of whole long span in place after, from right
In press-fit.
In the apparatus, base plays a part of forming a connecting link, and by framework and floating drum, centrally through sleeve control, the two is same
Axle degree, floating drum can be oriented to along hub internal bore and smoothly be installed in place, and floating drum two ends positioning span length is solved well from centering
The problem of, crossing positioning (double interference), two ends press-fit is by base and framework(frame of reference A), sleeve and floating drum
It is radially displaceable or crooked that effectively both the limitations of major diameter fit gap press-fit process.
The present invention design principle be：
1st, centre bore is utilized by framework machining benchmark A cylinders from the base of centering control deviceInsertion, is allowed to
Cylindrical coaxial with base, fit clearance is (0.003~0.006) mm, and mating surface is about 10mm, and effective limiting frame is by axial force
Afterwards, radially play.
2nd, coordinate from centering control device base excircle orientation seam and sleeve inner stopper, make it concentric with framework.Sleeve
Endoporus is (0.008~0.010) mm with the cylindrical fit clearance of floating drum, and effect is still when having received positioning effects, to limit floating drum edge
Radial-play.
3rd, span length is controlled by sleeve, and floating drum total length is used as guiding along sleeve lining, it is ensured that floating drum is coaxial with framework
On the premise of, radial deflection space compression is to minimum when being axially moveable it.Hub internal bore is with the cylindrical fit clearance of floating drum
(0.008~0.010) mm.
4th, two ends are interference fitted, and diameter is big, and span is long, and lower end enters head and is oriented to not just, and upper end is with regard to deflection, it is impossible to enter position.By
The offset of framework, floating drum radially is limited respectively in base and sleeve, is crossed and is located through centralising device design so that
The precision that press-fits of the double interference of long span is effectively ensured.
