Description
Technical field
This utility model relates to a kind of target practice position measurement device for piston cooling nozzle performance test stand, particularly relates to a kind of target practice position measurement sensor for piston cooling nozzle performance test stand.
Background technology
Piston cooling nozzle (i.e. PCN) has extremely important effect as the important component part of automobile engine, the quality of its performance to lubrication, the cooling effect of engine movements piston.
As it is shown in figure 1, piston cooling nozzle is made up of check valve 1 and nozzle body 2, based on automobile engine specification, the multiformity of model, the specification of piston cooling nozzle, model are also a lot, but its version is substantially similar.
The target practice position measurement of piston cooling nozzle is exfactory inspection project, it is desirable to all products that dispatch from the factory are carried out 100% one hundred percent inspection test.
The definition of target practice position is: when charge oil pressure reaches regulation test force value, the position that oil bundle injection is hit.Detection Eligibility requirements such as FL.P68 type piston cooling nozzle: during charge oil pressure 400kPa, in oil bundle sprays into appointment region, flow is more than or equal to 90%.
Specified as it is shown in figure 1, oil bundle sprays into appointment district with the locus of the shape of wad cutter 3, size and central point thereof on target plate 4.The shape majority of wad cutter 3 is circular, and minority is abnormity.The specification of piston cooling nozzle, model are different, and the locus of the shape of its wad cutter 3, size and central point thereof requires difference.
The test of target practice position typically completes on piston cooling nozzle performance test stand, and the test opening pressure, closing presure, leakage flow, dredge oil amount etc. with it is together carried out.
At present, it is known that disclosed target practice position measurement method mainly have weight method, pattern-recognition method and artificial ocular estimate these three, but all there is the problem that measuring accuracy is not high enough in these three traditional method.
nullThe another kind of applicant of the present utility model research is for the target practice position measurement device of piston cooling nozzle performance test stand，Apply for a patent，Compare above-mentioned three kinds of its measuring accuracies of traditional method can be improved，Its structure such as Fig. 2、Fig. 3、Shown in Fig. 4 and Fig. 5，This target practice position measurement device 21 includes force cell 25、Umbrella shape target 27、Protection set 26、Installing plate 22、Orifice plate 23 and Z-shaped rebound 24，Installing plate 22 is generally " l " shaped plate，The vertical plate of installing plate 22 is provided with the installing hole (non-indicating note in figure) for being connected with fixture，The transverse plate place plane of installing plate 22 is mutually perpendicular to the central axis of the nozzle body 2 of piston cooling nozzle，On the transverse plate of installing plate 22 and it is each provided with vertical or oblique through hole (not shown) on orifice plate 23，Orifice plate 23 is installed on the transverse plate of installing plate 22 and the through hole of orifice plate 23 is positioned at the through hole of transverse plate of installing plate 22，The through hole of orifice plate 23 is positioned at the lower section of the spout of the nozzle body 2 with piston cooling nozzle，The umbrella shape target surface of umbrella shape target 27 is positioned at the lower section of the through hole of orifice plate 23，The lower end of the center bearing column of umbrella shape target 27 bottom is connected with the pressure input of force cell 25，Protection set 26 is set in center bearing column and the outside of force cell 25 of umbrella shape target 27 bottom，Gap between protection set 26 and the free end of force cell 25 is 0.5mm，The bottom of protection set 26 is provided with oil leaking hole，One end of Z-shaped rebound 24 is installed on below force cell 25 and the other end is installed on installing plate 22，Z-shaped rebound 24 is provided with cable-through hole (non-indicating note in figure)，The signal transmssion line of force cell 25 passes this cable-through hole.
