The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.Embodiment of the present utility model includes but not limited to the following example.
Embodiment 1
A kind of milling tool for multiple valve valve seat as shown in Figure 1, comprise the milling bar 3 that the body of rod by a plurality of same structures is threaded and forms, the milling bar 3 lower ends grinding head 7 that has been threaded, grinding head 7 lower end heaps are welded with a circle grinding layer 9, the described milling bar 3 upper ends bar 2 of shaking hands that has been threaded, any one body of rod of described milling bar 3 is provided with external screw thread 5, and external screw thread 5 threaded engagement have retainer ring 4.
The present embodiment is when implementing, select the retainer ring 4 with valve seat through-hole internal diameter same diameter, retainer ring 4 is coordinated with external screw thread 5, valve seat is vertically set level, tool grinding head 7 is entered to valve seat through-hole downwards, when the grinding layer 9 of head to be ground contacts with sealing surface of seat, with the hands hold the bar 2 of shaking hands, in horizontal plane centered by milling bar 3 turning tool, grinding layer 9 can grind sealing surface of seat; When grinding, on grinding layer 9 and sealing surface of seat, smear abrasive pastes, what guarantee to grind carrying out normally, fast and not damaging valve seat and instrument; Retainer ring 4 is identical with valve seat through-hole internal diameter, can keep milling bar 3 in through hole, to keep vertically, guarantees that grinding layer 9 can contact with sealing surface of seat all the time uniformly, guarantees to grind completely; In the time need to grinding the sealing surface of seat of different bores, only need to change the grinding head 7 matching with sealing surface of seat, suitably add again or take out the unnecessary body of rod and can grind, simultaneously when a certain parts damages of instrument, only need to change the parts that damage, still can using of other, not only practical, and reduced the waste of material; The present embodiment can grind sealing surface of seat by this instrument, and the valve seat that can be used for many bores grinds, by valve corrosion and rough sealing surface grinds smooth, again realize sealing, it is convenient not only to grind, and very practical, guaranteed the permanent sealing of valve, practical.
Embodiment 2
The present embodiment has been optimized following structure on the basis of embodiment 1: this instrument is also provided with intercommunicating pore 6, intercommunicating pore 6 runs through milling bar 3 and the bar 2 of shaking hands, and intercommunicating pore 6 upper ends are from bar 2 intermediate openings of shaking hands, described intercommunicating pore 6 lower ends are positioned at grinding head 7, and grinding head 7 peripheries are also tilted to and are arranged with the through hole 8 being communicated with intercommunicating pore 6.
When reality is ground, can ceaselessly add according to grinding situation the abrasive pastes of variable concentrations, therefore, in order to facilitate staff to add abrasive pastes, need not take out whole instrument, so intercommunicating pore 6 and through hole 8 are set, staff can pour into abrasive pastes in valve seat by intercommunicating pore 6, and flow to sealing surface grinding place by through hole 8, saved man-hour, also can pass into the clean valve seat of clean water simultaneously, achieved many things at one stroke.
As preferably, described in bar 2 upper center of shaking hands be also provided with weight 1, described intercommunicating pore 6 runs through weight 1.Staff is when using tool grinding, in order to make grinding effect better, complete faster grinding, need to when bar 2 is shaken hands in rotation, to the bar 2 of shaking hands, apply a downward power, increase the interaction of abradant surface, therefore, for the amount of labour reducing a staff, hand lever 2 upper center of being in one's hands are also provided with weight 1, and weight 1 is exerted pressure to abradant surface by gravity, thereby alleviate staff's the amount of labour, also increased grinding effect.
As preferably, between the described body of rod and the body of rod, between the body of rod and the grinding head 7 and junction between the body of rod and the bar of shaking hands (2) is provided with sealing ring 10.For preventing that abrasive pastes spill and cause loss from interface when adding hydro-abrasion cream, affect and judge normally adding with staff's milling time of abrasive pastes, reduce the use of abrasive pastes, so sealing ring 10 is set for sealing the company headquarters place between all parts simultaneously.
Embodiment 3
The present embodiment has been optimized the structure of pressing plate on the basis of embodiment 1 or embodiment 2, is specially: described grinding layer 9 materials are 15CrMo steel.
In the certain thickness of 15CrMo steel surface, there are high rigidity, high-wearing feature and high fatigue strength, can use for a long time and can not wear and tear, in the present embodiment, grinding layer 9 adopts 15CrMo steel can realize two objects: first object is exactly to utilize the service life of the high abrasion characteristic prolongation grinding layer 9 of 15CrMo, prevent from occurring surface abrasion after it from repeatedly grinding and affect the grinding of sealing surface of seat, avoiding making the same out-of-flatness of sealing surface of seat because of the air spots of grinding layer 9; Second object be exactly general valve seat be all to adopt cr metalloid as seal face materials, and cr class material hardness is higher, general metal is difficult for sealing surface to polish, and also need to spend larger power and more time to go to grind, therefore in the present embodiment, grinding layer 9 adopts 15CrMo steel can utilize its high rigidity characteristic to enter sealing surface well to grind, grind laborsaving, fast, not only facilitated grinding, also can improve grinding effect simultaneously.
Embodiment 4
The present embodiment is further optimized on the basis of above-mentioned arbitrary embodiment, is specially: described retainer ring 4 is provided with the vertical through hole 11 of vertical connection.
The present embodiment lower end and valve seat through-hole when preventing that instrument from taking out in valve seat form vacuum and should not take out, so establish the vertical through hole 11 of vertical connection at retainer ring 4, vertically through hole 11 will be in communication with the outside in through hole, can prevent from occurring vacuum facilitating the taking-up of instrument in valve seat through-hole.
Embodiment 5
The present embodiment has been done following optimization on the basis of above-mentioned arbitrary embodiment: described grinding head 7 and milling bar 3 are made for stainless steel.
While grinding due to sealing surface of seat, need to avoid impurity to enter into abradant surface, prevent that impurity from impacting grinding, therefore, when grinding, need to keep the clean of abradant surface, and grinding head 7 and milling bar 3 can be avoided it for stainless steel and get rusty, when grinding, just do not have iron filings etc. and drop to grinding place, simultaneous grinding head 7 and milling bar 3 adopt stainless steels to be also difficult for being corroded, and can use for a long time.
Be as mentioned above embodiment of the present utility model.The utility model is not limited to above-mentioned embodiment, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, within all falling into protection domain of the present utility model.
