Abstract
The utility model relates to an oil blanket fixer for valve embeds quartering hammer includes oil blanket installation base member and supports the cover, support the cover and install the lower part at oil blanket installation base member, be equipped with the lubrication groove on the inner wall of support cover, be equipped with the helicla flute on the outer wall of support cover, support cover and oil blanket installation base member interference fit, the internal diameter that supports the cover slightly is less than the internal diameter of oil blanket installation base member, it is alloy copper to support the cover material. Prevent that the piston from wearing and tearing, preventing hydraulic oil seepage, work efficiency height.
Description
Technical field
This utility model is related to a kind of oil sealing holder, and more particularly, to a kind of oil sealing for the built-in quartering hammer of valve is fixed
Device, belongs to Hydraulic Field.
Background technology
The oil sealing holder of the large-scale quartering hammer of prior art, the support set of unprotected piston.Holder is installed
In cylinder sleeve, multiple tracks oil sealing is installed on the holder.When destroyer misoperation or when working long hours, oil sealing can wear and tear,
Steel oil sealing holder is made to produce friction with piston, such piston face occurs that cut namely scratches, so that hydraulic oil is let out
Dew increase, in the course of time destroyer cannot normal work, reduce quartering hammer work efficiency.
Utility model content
This utility model is directed to deficiency, provides a kind of antiseep, anti-wear, the built-in quartering hammer oil sealing of efficient valve to fix
Device.
The technical scheme that this utility model solves above-mentioned technical problem is as follows：A kind of oil sealing for the built-in quartering hammer of valve is solid
Determine device, including oil sealing installing matrix and support set, described oil sealing installing matrix is provided with multiple tracks oil sealing mounting groove, described oil sealing peace
Dress matrix underpart is provided with annular groove, and described support set is arranged in described annular groove, and the inwall of described support set is provided with
Lubrication groove, the outer wall of described support set is provided with helicla flute.
On the basis of technique scheme, this utility model can also do following improvement.
Further, the internal diameter of described support set is less than the internal diameter of oil sealing installing matrix.
Further, described support set and oil sealing installing matrix interference fit.
Further, described support set and piston clearance coordinate.
Further, described support cover material is alloyed copper.
The beneficial effects of the utility model are：Increased the support set of protection piston, ensure that oil sealing holder to work
The axial constraint power of plug, prevents piston wear, support set increased lubrication groove and helicla flute reduces between support set and piston
Friction, lubrication is more abundant, reduces oil sealing holder fault rate, improves work efficiency.
Brief description
Fig. 1 is this utility model structural representation；
Fig. 2 is support set schematic diagram in this utility model；
Fig. 3 is the oil sealing fixer structure schematic diagram of prior art；
In the accompanying drawings, the list of designations represented by each label is as follows：1st, oil sealing installing matrix, 2, support set, 3, oil
Envelope mounting groove, 4, lubrication groove, 5, annular groove, 6 helicla flutes, 7, the oil sealing holder of prior art.
Specific embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example is served only for explaining this practicality
New, it is not intended to limit scope of the present utility model.
As shown in figure 3, being the oil sealing holder 1 of prior art, piston is arranged in oil sealing holder, when high speed piston fortune
During dynamic or stress vibrations, and steel oil sealing holder directly contact, piston wear is serious, reduces work efficiency.
As shown in Figure 1, 2, a kind of oil sealing holder for the built-in quartering hammer of valve, including oil sealing installing matrix 1 and support
Set 2, described oil sealing installing matrix 1 is provided with multiple tracks oil sealing mounting groove 3, and described oil sealing installing matrix 1 bottom is provided with annular groove
5, described support set 2 is arranged in described annular groove 5, and the inwall of described support set 2 is provided with lubrication groove 4, described support set 2
Outer wall be provided with helicla flute 6.
The internal diameter of described support set 2 is slightly less than the internal diameter of oil sealing installing matrix 1.Described support set 2 and oil sealing installing matrix 1
Interference fit.Described support set 2 and piston clearance cooperation.
When piston hits appearance concussion, support set 2 holds onto piston, makes piston crooked too big, prevents from scratching and lives
Plug.Lubrication groove 3 on support set 2 outer wall, reduces the direct friction of support set 2 and piston, the helicla flute 6 on support set 2 outer wall
The adhesive force between support set 2 and oil sealing installing matrix 1 can be increased.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all in this practicality
Within new spirit and principle, any modification, equivalent substitution and improvement made etc., should be included in guarantor of the present utility model
Within the scope of shield.
