A kind of regulator bolts machining tool disclosed in the present embodiment, as shown in Figures 2 and 3, including is sheathed on regulator bolts 1
Screw rod 3 on sleeve 6, the internal diameter of sleeve 6 is equal to the external diameter of the screw rod 3 of regulator bolts 1 so that sleeve 6 can be with pressure regulation spiral shell
The screw rod 3 of bolt 1 combines even closer, is not susceptible to rock.
The external diameter of sleeve 6 is more than or equal to the external diameter of the pressure regulation bar 2 of regulator bolts 1, in the present embodiment, the external diameter of sleeve 6
The preferably equal to external diameter of pressure regulation bar 2, so that the outer peripheral face of sleeve 6 can be with the outer peripheral face flush of pressure regulation bar 2.The length of sleeve 6
Degree is more than or equal to the length of the screw rod 3 of regulator bolts 1, when sleeve 6 is sheathed on the screw rod 3 of regulator bolts 1, the end of screw rod 3
Portion is without departing from the one end of sleeve 6 away from pressure regulation bar 2.
It is in coniform guide post 7 that the one end of sleeve 6 away from pressure regulation bar 2, which is provided with, for the ease of statement, by guide post 7
Circular end face be defined as the bottom surface of guide post 7, the end away from its bottom surface on guide post 7 is defined as to the tip of guide post 7.
The bottom surface of guide post 7 is mutually fixed with end face of the sleeve 6 away from pressure regulation bar 2, the length direction one of its high line and sleeve 6
Cause, and the outer peripheral face flush at the bottom surface edge of guide post 7 and sleeve 6.Meanwhile it is connected edge between sleeve 6 and guide post 7
It is excessive by arc surface 16.The diameter of outer peripheral face corresponding to the medium position of guide post 7 is equal to the internal diameter of sealing ring 5.
The tip of guide post 7 is outward extended with the limited post 8 being arranged for sealing ring 5, and the external diameter of limited post 8 is less than sealing ring
5 internal diameter, so that the sealing ring 5 being sheathed on limited post 8 can move freely.
The one end of limited post 8 away from guide post 7 is provided with limiting plate 9, and the plate face of the limiting plate 9 is preferably circular, limiting plate 9
Diameter be more than sealing ring 5 internal diameter, so as to limit the axial location of sealing ring 5, so that sealing ring 5 can not depart from limit
Position post 8.
Limiting plate 9 is detachably connected with limited post 8, more specifically, the one end of limited post 8 away from guide post 7 stretches out
There is threaded rod 10, the threaded rod 10 is in be coaxially disposed with limited post 8.The plate face center of limiting plate 9 is offered for the spiral shell of threaded rod 10
The screwed hole 11 of line connection, so as to facilitate limiting plate 9 to be dismounted.
It is articulated on limited post 8 close to one end of guide post 7 and the tip of guide post 7.More specifically, limited post 8 is close
One end of guide post 7 is outward extended with pivot connecting plate 12, and the board direction of the pivot connecting plate 12 is consistent with the length direction of sleeve 6.Draw
The tip of guide pillar 7 offers the pivot connected slot 13 housed for pivot connecting plate 12, and two sides of pivot connecting plate 12 are outward extended with pivot joint
Axle 14, offered in two relative side walls in pivot connected slot 13 and rotate the pivoted hole 15 worn for two drive-connecting shafts 14 respectively,
And the circular arc for being adapted to its rotary motion trace is provided with the end of pivot connecting plate 12 so that limited post 8, which can be stablized, swimmingly to be guided
The tip of post 7 is turned down, without hindered.
Specific work process is as follows：
When using regulator bolts machining tool, first limiting plate 9 is backed out from the threaded rod 10 of limited post 8, then will
Multiple sealing rings 5 are inserted on limited post 8 successively, and the quantity being put into is less than the length of limited post 8 because of the thickness stacked with sealing ring 5
It is defined.After discharging sealing ring 5, limiting plate 9 is threadedly coupled on threaded rod 10 again by screwed hole 11, to limit sealing
The position of circle 5.
When assembling sealing ring 5, first by 6 sets of screw rods 3 for being set to regulator bolts 1 of sleeve, and make sleeve 6 away from guide post
7 one end is connected on the end face of pressure regulation bar 2.Then limited post 8 is overturn to the position consistent with the length direction of sleeve 6,
And a sealing ring 5 on limited post 8 near guide post 7 is moved and is inserted in the circular conical surface of guide post 7, then turn down
Limited post 8, state as shown in Figure 4 is formed, so that the length direction of the length direction of limited post 8 and sleeve 6 is inconsistent, so as to
The mobile route of other sealing rings 5 is blocked, avoids other sealing rings 5 from then moving on the circular conical surface of guide post 7.
Then the position of the sealing ring 5 towards the sleeve 6 that have moved on guide post 7 is pushed away, so that on guide post 7
Relatively moved between the inner circle of circular conical surface and sealing ring 5.In the process, the guide post 7 being arranged in sealing ring 5 it is straight
Footpath gradually expands, so that sealing ring 5 under the extruding of the circular conical surface of guide post 7, overcomes its own elastic force and expanded, until movement
To the outer peripheral face of sleeve 6.Then continue to translate sealing ring 5, because the outer peripheral face of sleeve 6 is equal with the outer peripheral face of pressure regulation bar 2
Together so that sealing ring 5 can effortlessly be moved and is sheathed with pressure regulation bar 2 very much, then move sealing ring 5 further along, by it
It is caught in annular groove 4, just completes the installation of sealing ring 5.
After the completion of assembling, sleeve 6 is removed from the screw rod 3 of regulator bolts 1.
