Description
Technical field
The utility model relates to engine art, particularly a kind of target practice device of piston spraying hook.
Background technology
Under normal circumstances, engine, when part such as replacing piston, cooling spray hook etc., all needs the target practice test carrying out piston cooling spray hook after assembling process or assembling complete, to determine whether piston met the demands with coordinating of piston cooling spray hook.
In the performance history of engine, the piston target practice apparatus of specialty cannot be used to carry out spray hook target practice test because the reasons such as quantity is few, test technology is imperfect, the assembly hardware of new product development does not possess installed by model machine.If spray hook installation site is inaccurate, machine oil cannot be injected in the scope of technical requirement exactly, easily causes engine piston temperature too high, affect piston even engine life in serviceable life.Although carry out spray hook practice shooting test, due to standard target practice line for engine reach the standard grade practice shooting have strict annex requirement, this just relates to the very large engine peripheral element disassemble and assemble work of workload, and therefore testing efficiency is low.
The information being disclosed in this background technology part is only intended to increase the understanding to general background of the present utility model, and should not be regarded as admitting or imply in any form that this information structure has been prior art that persons skilled in the art are known.
Utility model content
The purpose of this utility model is the target practice device providing a kind of piston spraying hook, thus the engine overcome in exploitation does not spray the inefficient defect of hook target practice test or spray hook target practice test.
For achieving the above object, the utility model provides a kind of target practice device of piston spraying hook, and target practice device comprises: spray hook seat, and spray hook seat is provided with tapped through hole, the sidewall of tapped through hole is provided with spray hook mounting hole, the axis of spray hook mounting hole and the axes normal of tapped through hole; Spray hook, one end of spray hook is arranged in spray hook mounting hole; Transition piece, transition piece is threaded connection and is arranged in tapped through hole, and the center of transition piece is provided with oil duct, and position corresponding with spray hook mounting hole on the sidewall of oil duct is provided with oil-through hole; Fuel feed pump, one end of fuel feed pump is connected with oil duct; Target practice liquid hold-up vessel, the oil-out of target practice liquid hold-up vessel is connected with the other end of fuel feed pump.
Preferably, in technique scheme, transition piece was oil draining bolt, and oil duct is axially through along crossing oil draining bolt, and one end of oil duct is connected with fuel feed pump; Under duty, the other end of oil duct is closed.
Preferably, in technique scheme, compressed air hose is installed on the top of target practice liquid hold-up vessel, and compressed air hose is provided with pressure-regulating valve, and pressurized air makes the target practice liquid in target practice liquid hold-up vessel form high pressure liquid.
Compared with prior art, the utility model has following beneficial effect:
Structure and the use of target practice device of the present utility model are all simple, simple operation, and efficiency is high, and the engine in convenient exploitation carries out spray hook target practice test; Transition piece has done small change on original basis crossing oil draining bolt, and therefore cost is low, practical.
Accompanying drawing explanation
Fig. 1 is the structural drawing of the target practice device according to piston spraying hook of the present utility model.
Fig. 2 is the structural drawing according to target practice liquid hold-up vessel of the present utility model.
Main Reference Numerals illustrates:
1-sprays hook seat, and 11-tapped through hole, 2-transition piece, 21-oil duct, 3-sprays hook, 4-fuel feed pump, 5-target practice liquid hold-up vessel, 51-oil-out, 6-compressed air hose, 7-pressure-regulating valve, 8-compressed air source.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model not by the restriction of embodiment.
Clearly represent unless otherwise other, otherwise in whole instructions and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or ingredient, and do not get rid of other element or other ingredient.
As shown in Figure 1, spray hook seat 1, transition piece 2, spray hook 3, fuel feed pump 4 and target practice liquid hold-up vessel 5 is comprised according to the target practice device of the piston spraying hook of the utility model embodiment.
Spray hook seat 1 is provided with tapped through hole 11, and the sidewall of tapped through hole 11 is provided with the spray hook mounting hole for installing spray hook 3, the axis of spray hook mounting hole and the axes normal of tapped through hole 11.Transition piece 2 is threaded connection and is arranged in tapped through hole 11, and the center of transition piece 2 is provided with oil duct 21, and the sidewall of oil duct 21 is provided with oil-through hole, and the position of this oil-through hole is corresponding with the position of spray hook mounting hole.
The bottom of target practice liquid hold-up vessel 5 is provided with oil-out 51, and top is provided with compressed air hose 6, and the other end of compressed air hose 6 connects compressed air source 8, and compressed air hose 6 is provided with pressure-regulating valve 7.The two ends of fuel feed pump 3 connect oil-out 51 and oil duct 21 respectively.
