Description
Technical field
The utility model relates to engine test field, particularly a kind of high-powered engine spray hook target practice pick-up unit.
Background technology
Pistons work in engine is under the rugged surroundings of high temperature, high pressure, for preventing from causing because piston is overheated fusing, the distortion of piston, cause serious engine failure, present most engine all adopts the piston in cold hole in band, utilizing cooling spray hook to spray forces cooling into the lubricating oil of oil duct in piston to piston, the use of this structure is minimized the working temperature of engine piston, has significantly improved the reliability of engine.Due to piston cooling spray hook itself, piston cooling spray hook on engine mounting hole manufacturing accuracy, assemble the reasons such as improper, the lubricating oil drop point that piston cooling spray hook sprays can not drop on oil duct in piston aperture completely, so just do not reach the cooling effect of piston the best, for eliminating the generation of this phenomenon, on engine body, install after piston cooling spray hook, must be to its detection of practicing shooting.
But, for high-power Engine Series, its body is taller and bigger, and throw of poston is long, spray hook is distant to body end face, be directly up to get to the target practice plate of body end face from spray hook and spray at present the hook test of practicing shooting, it is many greatly that the distance of practicing shooting is hooked to plunger distance than reality spray, can cause spraying hook practice shooting detect not accurate enough, cause engine to be practiced shooting in the time that reality is used inaccurate, cause engine cool, insufficient lubrication, occur the significant troubles such as piston scorification, affect the normal use of engine.
Utility model content
The utility model is in order to overcome defect in above-mentioned prior art, and a kind of high-powered engine spray hook target practice pick-up unit is provided, and making to practice shooting, detection is more accurate, bias free.
For achieving the above object, the utility model provides a kind of high-powered engine spray hook target practice pick-up unit, comprising: fixed head, and it has viewport, and fixed head is used for being placed in the body end face of engine and providing support; Check-out console, it is circular, arranges target center blind hole on check-out console, and check-out console is fixedly connected with fixed head by support bar, and check-out console is used for stretching into the detection of practicing shooting of piston position place in the cylinder barrel of engine.
In technique scheme, on fixed head, be provided with the locating slot matching with the cylinder barrel boss of engine.
In technique scheme, the height of the width of fixed head and the body of engine is suitable, and the length of fixed head equals the distance between two cylinders of engine, and viewport is two and mates with two cylinder positions of engine; Check-out console is two and is fixedly connected with fixed head by identical support bar respectively, and two check-out consoles are used for to the detection of practicing shooting of two cylinders of engine simultaneously.
In technique scheme, support bar two ends are fixedly connected with check-out console by nut respectively with fixed head.
Compared with prior art, the utlity model has following beneficial effect: extend into cylinder barrel inner carrier position by design check-out console and detect, distance that spray is hooked to check-out console and real engine are sprayed be hooked to the distance of piston top consistent, detect accurate bias free, simultaneously, the target practice situation that once can simultaneously detect two cylinders, detection efficiency is high.

Embodiment
Below in conjunction with accompanying drawing, an embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subject to the restriction of embodiment.
As shown in Figure 1, high-powered engine that the present embodiment provides spray hook target practice pick-up unit is mainly the detections of practicing shooting of the cylinder barrel 103 inner carrier positions by check-out console 2 being stretched into engine, making to practice shooting, it is consistent with actual service condition to detect, guarantee to practice shooting precisely, and bias free.
As shown in Figure 2, the high-powered engine spray hook target practice pick-up unit that the present embodiment provides comprises fixed head 1 and check-out console 2, check-out console 2 is fixedly connected with fixed head 1 by support bar 3, on fixed head 1, be provided with viewport 11(referring to Fig. 3), the body end face 101(that fixed head 1 is used for being placed in engine is referring to Fig. 1) and provide support, in order to play fixation, on fixed head 1, be provided with the locating slot 12(matching with the cylinder barrel boss of engine referring to Fig. 4).Check-out console 2 is circular, slightly less than cylinder hole, can stretch into smoothly in cylinder and detect, and arranges that target center blind hole 21(is referring to Fig. 6 on check-out console 2), check-out console 2 is used for stretching into the detection of practicing shooting of piston position place in the cylinder barrel of engine.
As a kind of preferred embodiment, two cylinders that this pick-up unit can detect engine simultaneously detect, correspondingly, the body 10(of the width of fixed head 1 and engine is referring to Fig. 1 and Fig. 3) quite, the length of fixed head 1 is the distance between two cylinders of engine, viewport 11 is two and two cylinder 103 location matches (referring to Fig. 1) with engine, check-out console 2 is two and is fixedly connected with fixed head 1 by identical support bar 3 respectively, and two check-out consoles 2 are used for to the detection of practicing shooting of two cylinders of engine simultaneously.Support bar 3 two ends are fixedly connected with check-out console 2 by nut 31 and packing ring 32 respectively with fixed head 1, (referring to Fig. 1), particularly, support bar 3 is that two ends are all the screw-rod structure (referring to Fig. 7) of screw thread, and the Design of length of support bar 3 just makes check-out console 2 stretch into cylinder barrel inner carrier position.Fixed head 1 selects organic glass to make with check-out console 2.
This pick-up unit in use, check-out console 2 stretches in the cylinder barrel of corresponding engine, fixed head 1 is placed on the body end face 101 of body 10 of engine, and fixing by locating slot 12, spray hook atomizing of liquids in engine cylinder barrel, whether the liquid of observing the ejection of spray hook by viewport 11 reaches pre-designed target center blind hole 21, if just reaching target center blind hole 21 positions, atomizing of liquids detects as qualified, otherwise be defective, utilize this pick-up unit can make distance that spray is hooked to check-out console 2 and real engine spray to be hooked to the distance of piston top consistent, detect bias free, simultaneously, once can detect the target practice situation of two cylinders simultaneously, detection efficiency is high.
Disclosed is above only specific embodiment of the utility model, and still, the utility model is not limited thereto, and the changes that any person skilled in the art can think of all should fall into protection domain of the present utility model.
