Abstract
The utility model discloses an assembling radial hydraulic pressure expanding device for a damper, which comprises an upper ring and a lower ring. The upper ring and the lower ring are fixedly connected, a first pressure ring is sleeved on outer circles of the upper ring and the lower ring, a second pressure ring is sleeved on an outer circle of the first pressure ring, a lining ring is sleeved on an outer circle of the second pressure ring, an oil inlet pipeline is arranged on the upper ring, the first pressure ring and the lower ring, and the lower ring is provided with a plug of the oil inlet pipeline. The upper ring and the lower ring are fixedly connected via a bolt, and a sealing ring is disposed between end surfaces of the upper ring and the lower ring. After gaps are generated among assembling components via internal ultra-high-pressure radial expansion, relative parts are then mounted in the gaps, large interference close fit is converted into clearance fit, the parts can avoid drag marks and press marks due to the fact that the parts are tightened over during assembling, and success assembly of products is guaranteed.
Description
Technical field
The utility model relates to a kind of damper assembling hydraulic radial turgor pressure device, belongs to damper mounting technology field.
Background technology
In the damper assembling process, spring assembly, limited block and outer collar are big interference tight fit, and traditional assembly technology is that spring assembly, limited block are compressed into outer collar, and these parts are easy to weighed wounded, plucking, cause the assembling failure.
Summary of the invention
The purpose of the utility model is to provide in a kind of damper assembling process installs undamaged assembling turgor pressure device for big interference.
The technical scheme of the utility model is:
A kind of damper assembling hydraulic radial turgor pressure device; Comprise Shang Quan, Xia Quan, Shang Quan is fixedly connected with enclosing down, is set with first pressure coil on the outer ring of Shang Quan and following circle; Be set with second pressure coil on the outer ring of first pressure coil; Suit lining ring on the outer ring of second pressure coil, last circle, first pressure coil and Xia Quan are provided with in-line, and following circle is provided with the chock plug of in-line.
Shang Quan is connected through bolt with enclosing down.
Be provided with sealing ring between the end face of Shang Quan and following circle.
Beneficial effect: the utility model reinstalls correlated parts because of after adopting inner super-pressure to be radially expanded to make build-up member and producing the gap, is converted into matched in clearance to interference tight fit greatly; Part phenomenon can not occur pulling, weighing wounded during assembling because of tension, and pressure coil and lining ring employing composite, can return back to life size fast after the expansion pressure release during pressurization; Can reuse; Safe and reliable, also improve efficiency of assembling, ensure the successful assembling of product.

Among the figure: 1-base, 2-cushion block, 3-outer collar, 4-spring assembly, 4A-limited block, 5-high-pressure pump, 6-oil pipe, 7-pushing block, 8-last circle, 9-in-line, 10-bolt, 11-lining ring, 12---sealing ring, 13-the second pressure coil, 14-the first pressure coil, 15-chock plug, 16-enclose down.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further specified.
A kind of damper assembling hydraulic radial turgor pressure device; Comprise circle 8, enclose 16 down, on enclose 8 and be fixedly connected with following circle 16, on enclose 8 and be set with first pressure coil 14 with following the circle on 16 the outer ring; Be set with second pressure coil 13 on the outer ring of first pressure coil 14; Suit lining ring 11 on the outer ring of second pressure coil 13, on enclose 8, first pressure coil 14 and down circle 16 be provided with in-line 9, following enclose 16 be provided with in-line 9 chock plug 15.
Be provided with sealing ring 12 between the end face of last circle 8 and following circle 16.
The course of work: use high-pressure pneumatic pump 5 hydraulic oil to be squeezed in the in-line 9 of circle setting; Because the effect of hydraulic oil; First pressure coil 14, second pressure coil 13, lining ring 11 outwards expand; Tension is delivered on the outer collar 3 through the pushing block on the damper 7, spring assembly 4, limited block 4A, and outer collar 3 is risen big, measures the girth of outer collar 3 and controls the installation that swell increment is carried out part.Install pressure release, overcoat, 3 tighten up promptly and tightly combine with spring assembly 4 and limited block 4A.
Turgor pressure device installation process: block down the oilhole of circle 16 in-line 9 with chock plug 15, second pressure coil 13 of packing into successively, first pressure coil 14, lining ring 11 are put into and will be gone up circle 8 behind the sealing ring 12, enclose 10 connections of 16 usefulness bolts down.Above turgor pressure device is put into the base 1 of damper and cushion block 2, pushing block 7 are installed, again spring assembly 4, limited block 4A, outer collar 3 are packed into, insert the oil pipe pressurization and can realize turgor pressure work.
