Detailed description of the invention
As shown in the figure: the oil sealing pressure head assembly of the present embodiment, comprise pressure head component, pressure head component comprises pressure head 1 and oil sealing retaining sleeve 2, and oil sealing pressure head assembly also comprises coordinating with oil sealing retaining sleeve 2 provides radial chucking power to form the positioning component of outside fix to oil sealing 4 outside oil sealing 4.
In the present embodiment, pressure head 1 is slidably matched with the mode of self return after can pushing away oil sealing and moving down and oil sealing retaining sleeve 2, and oil sealing retaining sleeve 2 is formed with oil sealing accommodation space 3 in bottom; Wherein, pressure head 1 is column structure, and oil sealing retaining sleeve 2 center is provided with pressure head via hole, and oil sealing 4 is placed in oil sealing accommodation space 3 when mounted, forms location fixing by outside fix assembly.
In the present embodiment, outside fix assembly comprises place kick 5 and elasticity tighten ring 6, place kick 5 is circumferentially arranged in oil sealing retaining sleeve 2 and inner side sphere and oil sealing 4 contact outside be positioned in oil sealing accommodation space 3, and elasticity tighten ring 6 is arranged with the mode overcoat described place kick 5 being produced to certain radial load, by elasticity tighten ring 6 and place kick 5 with the use of, flexible positioning can be formed to the oil sealing be placed in oil sealing accommodation space 3, because elasticity tighten ring 6 has certain elasticity, when pressure head 1 promote oil sealing move down time, make elasticity tighten ring 6 radial outward dilations, thus oil sealing is fallen in accommodation space, wherein, elasticity tighten ring 6 is O shape circle, can be rubber or other have flexible material and make, place kick 5 can be rubber or metal material is made, in the present invention, place kick 5 adopts metal material to make, for steel ball body, there is good locating effect.
In the present embodiment, oil sealing retaining sleeve 2 is circumferentially furnished with several and communicates with oil sealing accommodation space 3 and for the location ball 7 of placement positioning ball 5, corresponding location ball 6 is also provided with the circumference annular groove 8 for installing described elasticity tighten ring 6; Can Fast Installation and dismounting.
In the present embodiment, pressure head 1 lower end is provided with guide part 9 and spacing and promote the spacing of oil sealing when moving down and push away platform 10 for axis, keeps gap to arrange inside guide part 9 outer circumferential side and the oil sealing being positioned in oil sealing accommodation space 3.
In the present embodiment, pressure head 1 assembly also comprises return spring 11 and spring capping 12, return spring 11 is coated at pressure head 1 and arranges, and spring capping 12 is coated at described pressure head 1 and is fixedly connected with by screw 15, and spring capping 12 can move axially relative to oil sealing retaining sleeve 2; Return spring 11 is spiral compression spring, for pressure head 1 return.
