It contradicts the two respectively and passes through the elastic component 1 of the lower installation board 2, the runner disk 4 is equipped with towards the one side of upper mounting plate 1
The screw rod 6 of upper mounting plate 1 is threadedly engaged and passed through with the upper mounting plate 1, passes through the structure of this programme, rotating wheel disk, spiral shell
Bar drives runner disk to move up and down, runner disk compression elastic piece one when moving downward, and applies one to valve seat by clamp system
Positive pressure, and the indicator and graduated scale of the screw rod other end show current pressure value, guarantee the accurate of pressure applied
Property and stability, improve valve seat spool grinding qualification rate, improve processing efficiency.
6 top of screw rod is equipped with the indicator 61 being rotatably assorted with it, and 6 two sides of screw rod are equipped with and are fixedly mounted on institute
The graduated scale 7 on upper mounting plate 1 is stated, 61 both ends of indicator offer the groove 62 for avoiding the graduated scale 7, the present embodiment
The indicator of use is only moved up and down by screw rod drive, and without rotating, graduated scale is arranged in parallel with screw rod, indicator
Signified position is the pressure value that current valve seat is subject to.
Several studs 8 for being mounted on periphery are equipped between the upper mounting plate 1 and lower installation board 2, the stud 8 is close
One end of upper mounting plate 1 is equipped with the double nut 81 for being clamped in 1 two sides of upper mounting plate, and double nut can be used for adjusting peace
The horizontality of loading board.
The clamp system 3 includes the pedestal 31 and clamping seats 32 connecting with the lower installation board 2, the clamping seats 32
Detachably installed with pedestal 31, be equipped on the clamping seats 32 with its cooperate after clamp the movable semi-ring 33 of valve seat excircle,
The clamping seats 32 are equipped with semi-circular boss 34, and described activity 33 one end of semi-ring and one end of the semi-circular boss 34 are hingedly pacified
The other end of dress, the other end and the semi-circular boss 34 of the activity semi-ring 33 is bolted.
The medium position of the stud 8 is equipped with stop nut 82, is equipped between the stop nut 82 and lower installation board 2
The elastic component 3 83 of the two is contradicted respectively, and the stove bolt 9 across the lower installation board 2 is installed on the pedestal 31, it is described small
Between bolt 9 and lower installation board 2 be equipped with contradict both elastic component 2 10, spool valve seat grinding after the completion of, hold handle to
On when lifting lower installation board, elastic component two and elastic component three also buffer function, after putting down this structure, elastic component two and elastic component
Three provide a restoring force, and lower installation board and pedestal is made to set back.
In addition, when elastic component one is applied to one pressure of pedestal, the gap of pedestal and lower installation board generation certain size,
The elastic component two being set on stove bolt can generate a contrary restoring force, but because of valve seat valve in the present embodiment
Core is mutually ground, and the size in this gap is very small, and the restoring force of elastic component two can be ignored.
It is equipped with cushion 21 between the pedestal 31 and lower installation board 2, plays damping, extends pedestal and lower installation board
Service life.
2 two sides of lower installation board are equipped with handle 22, and the side of the upper mounting plate 1 is equipped with several mounting ears 11, convenient
Installation.
Horizontal detection meter 12 is additionally provided on the clamping seats, for precisely holding the horizontal position of clamping seats.
The installation method of the present embodiment: being in graduated scale " 0 " position in indicator, i.e. elastic component one does not have decrement,
Spool is fixed on the spool grinding table of rotation, matched valve seat is put on spool, clamping seats are installed on valve seat,
It detects whether this structure is in substantially vertical state with level meter, two fixed support ears of upper backup pad is then fixed with bolt
Piece, utility model device installs.For the valve seat of same model, this operation need not just be done again by installing；Processing is not
With the valve seat of model, valve seat clamping seats are needed replacing, the fixed nut of valve seat clamping seats and pedestal bottom plate is unclamped, is changed novel
Number valve seat clamping seats, and corresponding spool height also changes, so needing to reinstall by previous step.
The workflow of the present embodiment: it is no more than yield limit, stiffness factor K and compression in spring distortional stress
Length x meets Hooke's law: F=K*x.According to Hooke's law formula, this structure passes through dials the runner disk with screw rod manually, wherein
Screw rod and upper mounting plate are screw thread pair cooperation, convert screw rod rotary motion to the translational motion of indicator vertical direction, indicate
Distance on the corresponding graduated scale of part is the compressed length of elastic component one, and the stiffness factor K of elastic component one is it is known that so root
According to recklessly can law can calculate the positive pressure that elastic component one at this time is applied to impact faces, ground according to spool and the contact surface of valve seat
Positive pressure requirement, rotating wheel disk needed for mill make indicator point to corresponding scale, and clamping seats are bolted with pedestal
Together, so the positive pressure that elastic component one generates is transmitted on valve seat clamping seats, valve seat is fastened in valve seat clamping seats, in
It is that the constant positive pressure that elastic component one generates is transmitted on the contact surface of spool and valve seat；
After reaching valve seat milling time, rotary spool workbench is closed, can be manually rotated the pressure of wheel disc release elastic component one
It is pointed at scale " 0 " scale to vernier, is used to clamp the spiral shell of valve seat with allen wrench release activity semi-ring and semi-circular boss
Bolt, opening activity semi-ring, both hands hold handle and up put mounting plate vertically, and it is multiple that elastic component three, which generates buffer brake by compression,
It prepares position.Three equally distributed stove bolts pass through lower installation board and connect with pedestal, by the elastic force of elastic component two by pedestal
It is pressed on lower installation board with cushion, when lower installation board up moves, elastic component two, which is deformed, to be resisted below stove bolt
The gravity of the pedestal of connection, valve seat clamping seats, up moves together with pedestal, valve seat clamping seats, until valve seat is detached from valve seat
Clamping seats, remove valve seat from spool, and both hands unclamp handle, and elastic component three, which resets, compresses lower installation board, complete unilateral spool with
The grinding of valve seat；
Spool on grinding table is shifted into other side, lapping liquid is coated in the spool face to be ground, grasps handle
Hand up lifts lower installation board, then valve seat is placed on spool, and unclamping handle enters valve seat in clamping seats, closes activity half
Ring makes valve seat in clamping seats without relative rotation with allen wrench clamping screw.Rotating wheel disk carries out above compress and grasps
Make, a spool two sides grinding terminates, and replaces next group of spool and valve seat, moves in circles.
