Detailed description of the invention
As shown in the figure: the oil sealing pressure head assembly of the present embodiment, including pressure head component, pressure head component includes pressure head 1
With oil sealing retaining sleeve 2, oil sealing pressure head assembly also includes coordinating outside oil sealing 4 oil sealing with oil sealing retaining sleeve 2
4 provide radially chucking power to form the positioning component of outside fix.
In the present embodiment, pressure head 1 slides with oil sealing retaining sleeve 2 in the way of self return after oil sealing moves down pushing away
Coordinating, oil sealing retaining sleeve 2 is formed with oil sealing accommodation space 3 in bottom；Wherein, pressure head 1 is column structure,
Oil sealing retaining sleeve 2 is provided centrally with pressure head via, and oil sealing 4 is placed in oil sealing accommodation space 3 when mounted,
Location is formed fixing by outside fix assembly.
In the present embodiment, outside fix assembly includes place kick 5 and elastic lock ring circle 6, place kick 5 circumferentially cloth
Oil sealing 4 contact outside being placed in oil sealing retaining sleeve 2 inner side sphere and be positioned in oil sealing accommodation space 3, bullet
Property lock ring circle 6 in the way of described place kick 5 is produced certain radial force overcoat arrange；By elastic lock ring circle
6 and place kick 5 with the use of, the oil sealing that is placed in oil sealing accommodation space 3 can be formed flexible positioning,
Owing to elastic lock ring circle 6 has certain elasticity, when pressure head 1 promotes oil sealing to move down so that elastic lock ring circle
6 radial outward dilations, so that oil sealing falls in accommodation space, wherein, elastic lock ring circle 6 is O shape
Circle, can be rubber or other resilient materials of tool are made, and place kick 5 can be rubber or metal material is made,
In the present invention, place kick 5 uses metal material to make, and for steel ball body, has preferable locating effect.
In the present embodiment, oil sealing retaining sleeve 2 is circumferentially disposed with several and communicates also with oil sealing accommodation space 3
For the location ball 7 of placement positioning ball 5, corresponding location ball 6 is additionally provided with for installing described elasticity tight
