Abstract
The utility model discloses an axle seal installation instrument, its characterized in that: the collar includes radial holding surface, axial holding surface, hole circular conical surface, and axial holding surface external diameter is greater than the minimum internal diameter of hole circular conical surface and the cross section diameter that its width is greater than the sealing washer, the minimum internal diameter adaptation of hole circular conical surface just slightly is greater than the outside diameter of shaft that needs the installation sealing washer in the sealed size of the reservation of sealing washer. The aggregate erection instrument can also be constituteed with the guide ring to the collar. During the installation, with direct telescope of sealing washer or the axial holding surface through guide ring telescope collar, remove epaxial seal groove left side with the collar, push seal groove with the sealing washer, with the collar according to taking out in the other direction, the extrusion of hole circular conical surface makes the sealing washer resizing that the expansion warp, repeated above -mentioned step a plurality of sealing washers of can packing into. Utilize this kind of axle seal installation instrument and the installation method can a plurality of sealing washers easy to assemble, to the cut wound of sealing washer in the time of can preventing follow -up component assembly moreover.
Description
Technical field
This utility model belongs to mechanical equipment installation technical field, is specifically related to a kind of sealing installation tool.
Background technology
Sealing ring is widely used in the equipment needing to completely cut off media flow, and sealing is mounted in the cylinder being similar to piston rod
Sealed groove in sealing ring.The mode of existing installation sealing has following several: 1, by artificial hands by sealing ring
Packing into after pulling open in sealed groove, this mode operating efficiency ratio is relatively low, wastes time and energy；For the sealing ring that elasticity is poor, peace
Dress workman usually uses the aids such as screwdriver to carry out " not dress ", and this easily causes sealing ring or body of rod surface damage to hinder,
Have a strong impact on sealing effectiveness, cause leakage problem.Especially when the body of rod needs to install multiple sealing ring, close owing to installing rear end
Need during seal to cross over forward end seal groove, adopt the most aobvious inconvenience.2, a kind of one section is used to be set to cone
Sealing ring guiding expanding device discloses a kind of sealing as aid, such as Chinese utility model patent CN 203831341U
Circle assembling import tool, including fairlead, sealing ring compressing member and the sealing ring pushing means of band tapering, on described fairlead
Being provided with the conical surface placing sealing ring, described sealing ring compressing member pushes against sealing ring, and described sealing ring pushing means pushes against sealing ring pressure
Tight part.Adopt and the installation effect that can play improvement compared to manual installation is installed in this way, but multiple for install on the body of rod
During sealing ring, need to process multiple frock, bring burden to production；Simultaneously as sealing ring there occurs expansion in installation process
Open deformation, and the resizing voluntarily that sealing ring is in sealed groove is the longest, easily causes it in further installation procedures
His part incised wound to sealing, affects sealing effectiveness, causes the problems such as leakage.
Utility model content
For solving the problems referred to above, this utility model aims to provide one and installs for the most multiple sealing of sealing and can make close
Seal resizing in the trench, prevents the installation tool of follow-up incised wound.
The technical scheme that this utility model solves the problems referred to above and provided is a kind of mounting ring, including radial support face, axially supports
Face, endoporus taper seat, the external diameter of described axial support surface is more than sealing ring more than minimum diameter and its width of endoporus taper seat
Cross section diameter；The minimum diameter of described endoporus taper seat adapts to the predetermined closure size of sealing ring and slightly larger than installing sealing ring
The external diameter of axle.
As the improvement of above-mentioned sealing installation tool, mounting ring can be with guide ring composition combination installation tool, and guide ring passes through
Seam coordinates with mounting ring, is taper seat on the right side of guide ring, and the installation for some elastic poor sealing ring guides.
Use above-mentioned sealing installation tool, on the one hand, owing to mounting ring can be free to move axially, be therefore completely suitable for many
The installation of individual sealing ring；On the other hand, utilize the extruding to sealing ring during exiting of the endoporus conical surface of mounting ring, contribute to
The fast quick-recovery of sealing ring size, prevents the incised wound to sealing ring during subsequent parts is assembled, it is possible to reach time saving and energy saving,
Ensure the effect of sealing effectiveness.

In figure: 1, mounting ring；1.1, radial support face；1.2 axial support surface；1.3, endoporus taper seat；2, guide ring；
2.1, seam；2.2, taper seat；3, sealing ring；4, axle；4.1,4.2, sealed groove.
Detailed description of the invention
Below in conjunction with the accompanying drawings, detailed description of the invention of the present utility model is illustrated.
Mounting ring 1 shown in Fig. 1 includes radial support face 1.1, axial support surface 1.2, endoporus taper seat 1.3, described axial
The outside diameter d 2 in support face 1.2 more than the minimum diameter d1 of endoporus taper seat 1.3 and its width more than the cross section diameter of sealing ring 3；
The minimum diameter d1 of described endoporus taper seat 1.3 adapts to the predetermined closure size of sealing ring 3 and slightly larger than installing sealing ring 3
The outside diameter d 3 of axle 4.Axial support surface 1.2 end rounding, will not damage sealing ring surface when being so inserted in by sealing ring 3.
As a kind of preferred version, especially to the sealing ring that partial elastic is poor, it is possible to use mounting ring 1 and guide ring 2 form
Combination installation tool, guide ring 2 is coordinated with mounting ring 1 by seam 2.1.When sealing ring is installed, first sealing ring 3 is inserted in
Taper seat 2.2, then manually or with driving tool, sealing ring 3 is pushed the axial support surface 1.2 of mounting ring.
After above-mentioned steps completes, move to mounting ring 1, on the left of the sealed groove 4.1 on axle 4, sealing ring 3 be pushed sealing
Groove 4.1, takes out mounting ring 1 according to opposite direction；According still further to above-mentioned steps, sealing ring 3 is loaded sealed groove 4.2, according to this
Analogize, sealing ring 3 is loaded sealed groove one by one.Certainly, for sealing ring that partial cross section diameter is less, it is also possible to directly
Multiple sealing rings are inserted in advance the axial support surface 1.2 of mounting ring, so can disposably realize the peace of multiple sealing ring
Dress.During mounting ring 1 exits, the suitable rate of withdraw that slows down, the endoporus taper seat of mounting ring 1 can be made deformation
The extruding of sealing ring 3 is more abundant, the beneficially size restoration of sealing ring 3.Minimum diameter d1 due to endoporus taper seat 1.3
Adapt to the predetermined closure size of sealing ring 3, after mounting ring exits completely, can substantially realize sealing ring and reach predetermined sealing chi
Very little, it is ensured that sealing effectiveness.
