Description
Technical field
This utility model relates to field of machining, is specifically related to orifice plate extrusion clamp.
Background technology
Orifice plate is one of core component of common-rail injector.Owing to common-rail injector uses high pressure, the signal of telecommunication to be controlled,
Can timing, the quantitative oil spout controlling oil nozzle exactly.Its operation principle, the instruction that common-rail injector is sent by ECU, by electricity
Magnet valve controls the on an off of orifice plate spill port, when electromagnetic valve obtains electric, and orifice plate spill port is opened, under hydraulic control chamber oil pressure is rapid
Fall, at this moment spindle lifts, oil nozzle commencement of fuel injection.Electromagnetic valve dead electricity, spill port closes, and hydraulic control cavity pressure is rapidly and rail pressure phase
With, promote spindle to close needle-valve, end of injection.Common-rail injector is made preferably to solve fuel economy and dynamic property, fall
Low diesel emission.At present, two crossing inclined holes of orifice plate are when extruding, and clamping is relatively difficult, and clamping is the longest, and
The through hole in the middle of bottom orifice plate is usually scratched when extruding.
Summary of the invention
The technical problems to be solved in the utility model is to provide orifice plate extrusion clamp, solves two of prior art orifice plate
The oblique hole problem that clamping is relatively difficult and the longest when extruding.
This utility model is achieved through the following technical solutions:
Orifice plate extrusion clamp, including base and compact heap, described base top is provided with groove, and the bottom surface of groove is provided with two
Individual bearing pin, the bottom of groove connects with outage, and the top of described compact heap is provided with oil-feed groove, and the bottom of this oil-feed groove connects
Being connected with fuel feed hole, the bottom of compact heap is provided with the first vertical core, the second vertical core and cross-drilled hole.
The further improvement project of this utility model is that the bottom outside of described base is provided with toroidal cavity, base and work
Make the fixing connection of table top.
This utility model further improvement project is, described fuel feed hole is located at the top of inclined hole outside orifice plate, described pressure
Tight block is cylindrical, and described first vertical core is coaxial with compact heap, and described second vertical core is coaxial with outage.
This utility model further improvement project is, the first vertical core and the second vertical core are connected by described cross-drilled hole, this cross-drilled hole
One end communicate through the lateral surface of compact heap with external, cross-drilled hole end is provided with fluid stopping block rubber.
This utility model further improvement project is, when orifice plate is clamped between base and compact heap, orifice plate bottom surface
Match with two bearing pins of groove floor in hole, two location, and the through hole of orifice plate right part and the second vertical core and outage are together
Axle.
This utility model compared with prior art, has the advantage that
1, this utility model simple in construction, convenient mounting and clamping is quick, uses plane and two pits to position, compact heap and base
When the oil duct of upper design achieves extruding, the flow direction of squeezed fluid flows to identical with duty liquid, can after intersecting inclined hole extruding
Ensure that orifice plate in use arrives traffic requirement；
2, squeezed fluid is after the first vertical core, the second vertical core and cross-drilled hole, discharges from outage, and middle leading to bottom orifice plate
The squeezed fluid not flowed at hole, thus avoid the through hole in the middle of bottom orifice plate and be scratched.
With embodiment, this utility model is described further below in conjunction with the accompanying drawings.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention

The bottom surface of 4 is provided with two bearing pins, and the bottom of groove 4 connects with outage 3, and the top of described compact heap 11 is provided with oil-feed groove 9,
The bottom of this oil-feed groove 9 is communicated with fuel feed hole 10, and the bottom of compact heap 11 is provided with first vertical core the 8, second vertical core 5 and cross-drilled hole
7, the bottom outside of described base 1 is provided with toroidal cavity, and base 1 is fixing with work top to be connected, and described fuel feed hole 3 is located at hole
The top of inclined hole outside plate, described compact heap 11 is cylindrical, and described first vertical core 8 is coaxial with compact heap 11, and described second erects
Hole 5 is coaxial with outage 3, and the first vertical core 8 is connected by described cross-drilled hole 7 with the second vertical core 5, and one end of this cross-drilled hole 7 passes compact heap
The lateral surface of 11 communicates with external, and cross-drilled hole 7 end is provided with fluid stopping block rubber 6, and orifice plate is clamped between base 1 and compact heap 11
Time, hole, two of orifice plate bottom surface location matches with two bearing pins of groove 4 bottom surface, and the through hole of orifice plate right part and the second vertical core
5 and outage 3 coaxial.
It should be pointed out that, for those skilled in the art, without departing from this utility model principle
On the premise of, it is also possible to making some improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model.
