Description
Technical field
The present invention relates to the partial structurtes of a kind of piston cooling nozzle performance test stand, particularly relate to a kind of target practice position measurement device for piston cooling nozzle performance test stand.
Background technology
Piston cooling nozzle (i.e. PCN) is as the important component part of automobile engine, and the lubrication of engine movements piston, cooling effect are had extremely important effect by the quality of its performance.
As it is shown in figure 1, piston cooling nozzle is made up of check valve 1 and nozzle body 2, based on the multiformity of automobile engine specification, 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, oil bundle spray into appointment region in flow be more than or equal to 90%.
As it is shown in figure 1, oil bundle sprays into designation area and is specified with the locus of the shape of wad cutter 3 on target plate 4, size and central point thereof. 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 to some extent.
The test of target practice position is typically on piston cooling nozzle performance test stand to complete, and the test opening pressure, closing presure, leakage flow, dredge oil amount etc. with it together carries out.
Traditional target practice position measurement adopts following three kinds of technical methods:
Method one: as shown in Figure 2, adopt artificial ocular estimate: high-pressure pump 5 provides high pressure for machine oil, manually regulate the aperture of ball valve 6, observe flow transducer 7 (in order to gather data, otherwise available stream scale) and pressure transducer 8 (in order to gather data, otherwise available pressure table) reading, when the pressure determining machine oil reaches target practice position measurement pressure, staff's range estimation sprays into the degree of the wad cutter 3 of target plate 4 from the oil bundle of nozzle body 2 injection, and whether artificial judgment is qualified.
Method two: as shown in Figure 3, adopt weight method: by the output pressure of program control adjustment pressure regulator 9, obtain the stable target practice position measurement pressure of a period of time, controlling twin shaft cylinder 14 during this drives baffle plate 11 to move, expose wad cutter 3, keep a period of time by setting value, then control twin shaft cylinder 14 and drive baffle plate 11 reversely to move, hide the wad cutter 3 of target plate 4; Effect due to wad cutter 3, when oil bundle injection target practice position is undesirable, a part for oil bundle can be ejected into the outside of wad cutter 3, and the machine oil that measuring cup 12 is collected is by minimizing, measuring collected machine oil weight with LOAD CELLS 13, it is qualified to determine whether by setting weight lower limit threshold values. Test opens, after terminating, the detection medium machine oil collected in electromagnet cut off valve 10 burst size measuring cup 12. The high-pressure pump 5 of Fig. 3, flow transducer 7 are identical with Fig. 2 with pressure transducer 8.
Method three: as shown in Figure 4 and Figure 5, adopt pattern-recognition method: apply constant target practice position measurement pressure to piston cooling nozzle, the image of oil beam jetted 17 is obtained by digital camera 18, carry out after image procossing through digital video processing system, obtain the angle of flare of oil beam jetted 17, inclination angle, as shown in Figure 6, determine whether with this qualified; Also show in Fig. 4 and also show source of parallel light 16 and illuminator 19 in jet box 15 and source of parallel light 16, Fig. 5, these parts are and realize digital camera 18 obtain the device of oil beam jetted 17 image for assisting.
The defect of above-mentioned three kinds of traditional methods is as follows:
Method one: need the aperture of manual adjustment manual adjustments ball valve 6, when obtaining target practice position measurement pressure, range estimation oil beam jetted sprays into the degree of the wad cutter 3 of target plate 4, whether artificial judgment is qualified, the detection efficiency of experimental stand is low, the labor intensity of operator is big, and the confidence level of testing result depends on operant skill and the responsibility of operator, not accurately.
Method two: require over the output pressure of program control adjustment pressure regulator 9, to obtain stable target practice position measurement pressure, and the adjustment of pressure regulator 9 output pressure is the iterative process of an Approach by inchmeal, it is necessary to consuming time, oil collecting needs enough amounts simultaneously, it is also required to consuming time, otherwise test error is relatively big, therefore, detects length consuming time, detection efficiency is too low, is not suitable for being applied to the production testing of piston cooling nozzle.
Method three: be only applicable to the situation that oil beam jetted 17 is cone, when not being inherently cone for desirable oil bundle, desirable oil bundle be that cone is because piston cooling nozzle nozzle configuration defect is then inapplicable when causing oil beam jetted not to be cone, but, one of rejecting purpose being by target practice position measurement of the nozzle configuration defect of the nozzle body of piston cooling nozzle, therefore, be not suitable for being applied to the production testing of piston cooling nozzle; Meanwhile, in the production testing of piston cooling nozzle, it is necessary to the continuous operation of frequent, there is the atomizating phenomenon of detection medium machine oil, the image quality of oil bundle pattern can be affected, cause producing bigger boundary error during image procossing; It addition, the camera lens of the tank wall of jet box 15, digital camera 18 also can condense, time serious, will be unable to imaging, it is also possible to cause that the method is difficult to carry out.
