Description
Technical field
The utility model belongs to hydraulic seal mounting technology, is related to one kind and is used for hydraulic sealing ring mistake proofing inspection and assembling
Frock.
Background technology
At present without the universal fixture for being used for hydraulic sealing ring mistake proofing inspection and assembling.Hydraulic sealing ring is mainly used in hydraulic pressure
The dynamic sealing of slide valve assembly and the static seal at crucial oil circuit position.Hydraulic sealing ring is needed according to detail of design in assembling process
It is required that the correct specification of installation, if there is the wrongly installed situation of sealing ring, will cause oil leak to occur, is influenced whether under serious conditions
Properties of product.Hydraulic sealing ring is divided into different specifications according to standard, and the sealing ring of adjacent-specification is closely sized to, non-specifically skillfully
Assembly crewman can not distinguish.
Utility model content
Technical problem to be solved in the utility model is：The frock is used for hydraulic sealing ring mistake proofing inspection and assembling, by
Taper top guide with sign checks cushion rubber size, and sealing ring is gradually loaded to the seal groove of hydraulic pressure valve pocket by cylindrical guide pin bushing
In, avoid traditional approach multi-drawing sealing ring from causing sealing ring hydraulic performance decline so that seal failure by seal groove.
Frock of the present utility model for hydraulic sealing ring mistake proofing inspection and assembling, by top guide and guide pin bushing two parts group
Into wherein the top guide includes the cone of upper end and the cylindrical fixed seat of lower end, in conical surface perpendicular to axis
Direction has had a datum line, upper tag line and lower tag line of mark action, a diameter of internal diameter of the seal ring at datum line, subscript
Know the half that linear distance datum line is sealing ring diameter of section, lower mark linear distance datum line is sealing ring diameter of section
Half；The guide pin bushing is abutted and seamlessly transitted with the cone by inserting the cylindrical fixed seat wherein,
The diameter of bore of guide pin bushing is consistent with product external diameter to be assembled.
It is rounded down at the top of the cone, prevents wedge angle from damaging sealing ring.The guide pin bushing and the cylindrical fixed seat
Gap coordinates.
It will first be inserted during use with tagged taper guide pin bushing in cylindrical guide pin bushing.The taper guide pin bushing of tape identification is used to check
Sealing ring and by sealing ring slow stretching to cylindrical guide pin bushing external diameter size, ensures sealing ring uniform force in drawing process,
Avoid because unbalance stress causes sealing ring hydraulic performance decline.Sealing ring after stretching is enclosed on cylindrical guide pin bushing, and guides sealing
Circle, which loads, to be housed in the seal groove of product.
The beneficial effects of the utility model are：A kind of frock for hydraulic sealing ring mistake proofing inspection and assembling is proposed,
The dimensions of sealing ring can not only be quickly checked, avoids misloading from occurring, additionally it is possible to sealing ring is quickly loaded into hydraulic pressure valve pocket
On corresponding seal groove, traditional approach multi-drawing sealing ring is avoided to cause sealing ring hydraulic performance decline so that sealing by seal groove
Failure.
Brief description of the drawings
Fig. 1 is the structural representation of top guide；
Fig. 2 is the structural representation of guide pin bushing.
Embodiment
The utility model is described in further details below.Referring to Fig. 1 and Fig. 2, one kind is used for hydraulic sealing ring mistake proofing
The frock for checking and assembling, it with tagged top guide 1 and the two parts of guide pin bushing 2 by forming.Knot with tagged taper top guide 1
Configuration formula is cone 1a, datum line 1b, upper tag line 1c, lower tag line 1d and cylindrical fixed seat 1e；Guide pin bushing 2 is thin-walled
Shape, its diameter of bore are consistent with product external diameter to be assembled and cylindrical fixed seat 1e diameters.It is rounded down at the top of cone 1a,
Prevent wedge angle from damaging sealing ring.Internal diameter of the seal ring is d0, diameter of section d1.Cone diameter at datum line 1b is in sealing ring
Footpath d0, upper tag line 1c lean on the small extreme direction of circular cone in datum line 1b, the half that the distance apart from datum line 1b is d1；Subscript
Know line 1d and lean on the big extreme direction of circular cone in datum line 1b, the half that the distance apart from datum line 1b is d1.
Cylindrical fixed seat 1e is inserted in the endoporus of guide pin bushing 2.Sealing ring is inserted in cone 1a in a free state during inspection,
If sealing ring is entirely fallen within the range of tag line 1c and lower tag line 1d, sealing ring size qualification, if not in upper tag line
In the range of 1c and lower tag line 1d, then sealing ring off-dimension.The sealing ring of size qualification is with the hands slowly pushed, made close
Seal is gradually stretched on the outer surface of guide pin bushing 2.Guide pin bushing 2 is removed, the endoporus of the guide pin bushing 2 equipped with qualified size sealing ring is inserted in
On product to be installed, to being housed at the seal groove of product.Qualified size sealing ring is slowly pushed into the sealing for being housed to product
In groove, guide pin bushing 2 is removed, that is, completes hydraulic sealing ring inspection and assembling process.
