Description
Technical field
The present invention relates to gate valve to produce and process mould applications, and specifically a kind of cam is automatically positioned processing drill jig.
Background technology
Gate valve is widely used as the control in fluid line induction system.The characteristics of gate valve is lock valve（Open and close part）,
By the vertical direction of valve channel center line, make upper and lower move along valve body guiding rib.
It was found from prior art, valve stem nut determines the position of lock valve, and valve rod determines the position of valve stem nut, retaining
Nut determines stem position again, and bonnet determines anti-return nut position, and the connecting bolt of valve body and bonnet limits bonnet position
Put.The connecting bolt of namely valve body and bonnet has influence on flap in the correct position of valve body.If position to not having influence on
Sealing property, open and close torque and the service life of valve.The connecting screw hole position of valve body and bonnet is to the quality of gate valve to closing weight
Will.
In the prior art, the screw processing method that head is connected with bonnet in gate valve body is as follows：
Bushing plate is placed on valve body, bushing plate is positioned：
1st, the center line on the center line alignment valve body on bushing plate.
2nd, the profile of bushing plate is alignd with the profile of valve body head.
Then it is fixed on by arm-tie, stud, nut on valve body, the screw being connected with bonnet can be carried out to valve body with that
Processing.
The positioning of traditional processing method is artificially alignd with the center line of valve body by the center line of bushing plate,
It is exactly manually to center line, the outer 50um of line, precision are very low in line.In addition the center line of determination valve body is also a time-consuming, quality
The work being difficult to ensure that.
The method of traditional bushing plate alignment valve body head is even more unreliable, because the tolerance of casting is very big, such as
Area of bed is 150x120mm in DN100, and casting is that the tolerance of molding sand machine molding spheroidal graphite cast-iron is 8-12 levels, tolerance 1.8-
7mm, so spray can not do positioning datum, that is, the tolerance of spray is too big, can not also match somebody with somebody on drill jig solid
Fixed interior locating device.
The content of the invention
The defects of it is an object of the invention to provide in order to overcome prior art to exist and deficiency, a kind of cam, which is automatically positioned, to be added
Work drill jig.
Technical scheme is as follows：
A kind of cam is automatically positioned processing drill jig, includes valve body, the left and right guiding rib on valve interior wall, is fixed on valve
The bushing plate and drill jig sleeve of body upper end, it is characterised in that：The middle part of the bushing plate is provided with through hole and is rotatablely equipped with vertical
The rotating shaft of setting, the upper and lower end of the rotating shaft extend from described through hole respectively, and the outer wall of rotating shaft upper end is provided with screw thread
And the locking nut being pressed on the bushing plate is screwed with, the lower end of rotating shaft has two relative projections, the bushing plate
Bottom be connected to left and right positioning seat in the both sides of the rotating shaft, the lower end of the left and right positioning seat be respectively equipped with it is left,
Right cross through hole, and have left and right telescopic shaft by being slidably installed respectively, the front end of the left and right telescopic shaft connects respectively
There is left and right locating piece, the front end of the left and right locating piece is respectively equipped with wedged hole, and described left and right guiding rib can correspond to respectively
It is inserted into the wedged hole of the left and right locating piece front end.
Described cam is automatically positioned processing drill jig, it is characterised in that：Between described locking nut and the bushing plate
Provided with plain cushion.
Described cam is automatically positioned processing drill jig, it is characterised in that：The outside of the left and right telescopic shaft is respectively installed with
Compression spring.
Beneficial effects of the present invention：
The present invention is rational in infrastructure, reliable, is not influenceed by Casting tolerance, form error, is symmetrically positioned in valve body, has self-locking
Performance, make the fixation of bushing plate and valve body and positioning more convenient, ensure that the quality of gate valve.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
Fig. 2 is Fig. 1 A-A to structure sectional view.
Embodiment
Referring to Fig. 1,2, a kind of cam is automatically positioned processing drill jig, includes valve body 1, left and right on the inwall of valve body 1
Guiding rib 2, the bushing plate 3 and drill jig sleeve 4 for being fixed on the upper end of valve body 1, the middle part of bushing plate 3, which is provided with through hole and is rotatablely equipped with, is in
Vertically arranged rotating shaft 5, the upper and lower end of rotating shaft 5 extend from through hole respectively, and the outer wall of the upper end of rotating shaft 5 is provided with screw thread simultaneously
The locking nut 6 being pressed on bushing plate 3 is screwed with, the lower end of rotating shaft 5 has two relative projections 7, the bottom of bushing plate 3
Left and right positioning seat 8 is connected in the both sides of rotating shaft, the lower end of left and right positioning seat 8 is respectively equipped with left and right cross through hole, and
There is left and right telescopic shaft 9 by being slidably installed respectively, the front end of left and right telescopic shaft 9 is connected to left and right locating piece 10,
The front end of left and right locating piece 10 is respectively equipped with wedged hole, left and right guiding rib 2 can correspond to respectively be inserted into left and right locating piece 10 before
In the wedged hole at end.
In the present invention, plain cushion 11 is provided between locking nut 6 and bushing plate 3.
The outside of left and right telescopic shaft 9 is respectively installed with compression spring 12.
Below in conjunction with accompanying drawing, the present invention is further illustrated：
Locking nut 6, rotating shaft 5 are loosened, two projections 7 for making its lower end relative contact with left and right telescopic shaft 9 respectively（Class
It is similar to the effect of cam）, two projections 7 promote left and right telescopic shaft 9 to be moved to both sides respectively, so that left and right locating piece 10 pastes
Tight left and right guiding rib 2.Because the parts such as two projections 7, left and right telescopic shaft 9, left and right locating piece 10 are in being to be symmetrical arranged
, installation site is also Striking symmetry, so the motion of two projections 7, left and right telescopic shaft 9, left and right locating piece 10 is also
Symmetrically.The positioning of bushing plate 3 is to rely on inclined-plane of the wedge hole with left and right guiding rib 2 of left and right locating piece 10, and by two
Projection 7 promotes left and right telescopic shaft 9 to be allowed to be automatically positioned.
When the pressure angle for increasing two projections 7 can be accomplished with self-lock ability, that is to say, that rotating shaft 5, make
While bushing plate 3 positions, the thrust of positioning will not reduce.When rotating shaft 5 causes left and right locating piece 10 to paste completely
Locking nut 6 is tightened after tight left and right guiding rib 2, it is possible to carries out the processing of the screw of valve body 1.
After completion of processing, locking nut 6 is loosened again, reversely rotates rotating shaft 5, left and right telescopic shaft 9 is in compression spring 12
Moved respectively to the direction of rotating shaft 5 under effect, drive left and right locating piece 10 to depart from respectively with left and right guiding rib 2.Then it is just desirable
Lower bushing plate 3 and drill jig sleeve 4.
From above-mentioned, the present invention is not influenceed by Casting tolerance, form error, is symmetrically positioned in valve body, is had certainly
Performance is locked, makes the fixation of bushing plate and valve body and positioning more convenient, ensures that the quality of gate valve.
