Background technique
Modern diesel engine generally adopts the high-pressure common rail electric jet technology, and this technology is meant in the closed-loop system that high pressure oil pump, pressure transducer and electronic control unit are formed, with the generation and the distinct each other a kind of fuel system of course of injection of jet pressure; It is by the high-pressure common rail oil pump; The high pressure oil rail pipe, common-rail injector and automatical control system are formed, and wherein the high-pressure common rail oil pump is extracted the low-voltage fuel in the fuel tank and be pressurized to about 200MPa out; And be stored in the common rail pipe; High pressure oil in the common rail pipe is communicated with common-rail injector, and automatical control system links to each other with solenoid valve on the common-rail injector through guide line, and applies control signal according to the working condition of internal-combustion engine to common-rail injector; The injection time and the fuel injection quantity of control common-rail injector are so that internal combustion engine is at optimum level.Can find out from above process; Whether most important the performance of common-rail injector is well to the working state of internal-combustion engine; So need timely performance to detect, generally be fixed on common-rail injector on the special-purpose test stand during test, and high pressure oil and control signal be provided to common-rail injector to common-rail injector; Its fuel injection quantity and recirculating oil quantity are measured, to judge the quality of common-rail injector.Present oil sprayer test clip assembling device is that oil sprayer to be tested is fixed in the fixed hole of oil sprayer fixed plate, and the high pressure oil rail pipe is coupled and feed high-potting oil, oil sprayer under the control of control signal according to the certain rules oil spout; The oil that the oil spout trap will spray from the nozzle opening of oil sprayer collects; Flow into oil mass metering device through oil pipe, O type circle is used for leakage test oil, and leans on frictional force between it and the fuel injector nozzle to guarantee that trap is unlikely to slip out from oil nozzle; This frictional force is that the oil spout trap is fixed on the unique strength on the oil sprayer; But because the pressure of the high pressure oil that from common-rail injector, sprays reaches as high as 200MPa, powerful impulse force is easy to the oil spout trap is washed out from oil nozzle; So this device work is unreliable, the defective of existing technology that Here it is place.
Summary of the invention
The purpose of the utility model is to overcome the shortcoming that exists in the existing technology; A kind of easy to use, convenient quick, fixing reliable oil sprayer test exclusive clamps assembling device of connection of clamping is provided; It adopts cylinder column that the oil spout trap is upwards risen; Thereby increase the power that is connected between oil spout trap and the oil nozzle; To reach reliable and practical purpose, the technological scheme of employing is: a kind of oil sprayer test exclusive clamps assembling device is characterized in that: said oil sprayer test exclusive clamps assembling device comprises: the oil sprayer fixed cover that is used for fixing oil sprayer; The injector clamp support is fixedly connected with the oil sprayer fixed cover on the said injector clamp support; Cylinder, said cylinder are fixedly connected on the said injector clamp support, the cylinder column hollow in the said cylinder, and one of which is rectified the oil nozzle to said oil sprayer, and the other end is connected with oil mass metering device; Be positioned at the oil spout trap of said cylinder top, said oil nozzle is arranged in the oil spout trap, and said cylinder column is fixedly connected on the said oil spout trap over against an end of said oil nozzle; O type circle, said O type circle is positioned on the said oil spout trap.
The technical characteristics of the utility model also has: the oil sprayer that said oil sprayer fixed cover is fixedly connected on said injector clamp support is fixedly on the suspension.
The technical characteristics of the utility model also has: said cylinder is fixedly connected on the base plate of said injector clamp support.
The technical characteristics of the utility model also has: be connected with the cylinder set screw nut between said base plate and the said cylinder.
The beneficial effect of the utility model is: this exclusive clamps assembling device is simple in structure; Design science is reasonable; The oil spout trap that moves up and down with cylinder column can not only play good seal action to high-potting oil; And make the quickness and high efficiency more that clamps of oil sprayer, have the good advantage of using effect.
Description of drawings
Accompanying drawing 1 is the utility model structural representation, wherein, the 1st, oil sprayer, the 2nd, oil sprayer fixed cover; The 3rd, injector clamp support, the 4th, cylinder, the 5th, cylinder column, the 6th, oil nozzle; The 7th, oil mass metering device, the 8th, the oil spout trap, the 9th, O type circle, the 10th, oil sprayer is suspension fixedly; The 11st, solenoid valve, the 12nd, cylinder set screw nut, the 13rd, base plate.
Embodiment
Below in conjunction with accompanying drawing, the embodiment of the utility model is described.This oil sprayer test exclusive clamps assembling device comprises oil sprayer fixed cover 2, the injector clamp support 3 that is used for fixing oil sprayer 1, cylinder 4, oil spout trap 8 and O type circle 9.Oil sprayer 1 is fixed on the oil sprayer fixed cover 2, and injector clamp support 3 comprises oil sprayer fixedly suspension 10 and base plate 13, and oil sprayer fixed cover 2 is fixedly connected on oil sprayer fixedly on the suspension 10, and cylinder 4 is fixedly connected on the base plate 13 through cylinder set screw nut 12.Cylinder column 5 is arranged in cylinder 4; Cylinder column 5 is middle hollow type structures that have through hole; Cylinder column 5 one ends are fixed on the oil spout trap 8; And over against oil nozzle 6, the other end of cylinder column 5 passes cylinder 4 backs and is connected with oil mass metering device 7, thereby makes test oil received by oil mass metering device 7.Be provided with the O type circle 9 that plays seal action between oil spout trap 8 and the oil nozzle 6.
