Abstract
The utility model relates to a fuel injector performance testing assembly including an installation body and a transient piping pressing turnbuckle, an inspection hole is provided in the middle of the installation body, the turnbuckle makes use of engine assembly parts. The utility model is characterized in simple structure, low cost of material and manufacture, convenient usage, easy moving, appliance to different working occasions. The utility model applies to four air valve engine fuel injector performance testing assembly and also other fuel injector testing.
Description
Technical field
The utility model relates to a kind of oil sprayer test fixture, relates in particular to a kind of 4 air valve engines oil sprayer testing property frock.
Background technique
As everyone knows, in the engine development process, motor must be through the development experiments of too much wheel, and performance whether up to standard be the key index whether motor can criticize product, and the performance of oil sprayer has very important influence to the performance of motor.The oil sprayer performance detection can be undertaken by running engine, but performance detection such as oil bundle atomizing situation, needle opening pressure and debugging then need to be undertaken by test stand.4 air valve engines are because its oil sprayer layout has specific characteristics than 2 valves, and high-pressure oil pipe need be taken over by 1 transition that is installed in the cylinder body with being connected of oil sprayer and finish, and the detection of oil sprayer and debugging need fast.
Detecting at present and the debugging oil sprayer, is that oil sprayer and transition adapter are installed on the cylinder cap that matches, and high-pressure oil pipe is connected again, thereby oil sprayer is detected and debugs.Because cylinder cap Heavy Weight, volume are big, it is very inconvenient to move, and the cylinder cap consumptive material is many, the cost of possession height.
Therefore, a kind ofly oil sprayer and transition can be installed take over and both close fit but need design, and the frock that is used to detect oil sprayer simple in structure, that can move flexibly.
Summary of the invention
At the deficiencies in the prior art, the utility model provide a kind of simple in structure, can move flexibly, satisfy the engine fuel injector testing property frock of test request.
The utility model oil sprayer testing property frock comprises fixing body and transition adapter gland nut, fixing body is a column structure, fixing body one end is provided with mounting hole of oil sprayer, mounting hole of oil sprayer is the through-hole structure perpendicular to the fixing body axial direction, the fixing body middle part is axial hollow structure, this hollow structure constitutes transition and takes over mounting hole, transition is taken over mounting hole one end and is communicated with mounting hole of oil sprayer, transition is taken over the mounting hole the other end transition adapter gland nut of taking over the mounting hole concentric with transition is set, and observation panel is offered in side, fixing body middle part.
In the above-mentioned oil sprayer testing property of the utility model frock, fixing body is the column structure that at least one end has boss structure, preferably two ends are boss structure, if adopting an end is boss structure, then mounting hole of oil sprayer one end is set to boss structure, and projection section is convenient to be provided with mounting hole of oil sprayer and gland nut is taken in transition.The column structure of fixing body is cylinder or prism structure, and projection section also can be cylinder or prism structure, and the axle center of the cylinder of projection section or prism is vertical mutually with fixing body column structure concentric or axle center.Observation panel is arranged on the joint of mounting hole of oil sprayer and transition adapter, is convenient to observe the identical situation of butt joint of oil sprayer and transition adapter and be convenient to adjust oil sprayer oilhole present position.Gland nut one end is taken in the transition of fixing body can be provided with 2～6 fastening screws of fixing body, is used for fixing body is fixed on worktable.
Owing to adopt above-mentioned technological scheme, the utlity model has following beneficial effect:
1, simple in structure, material and processing cost are low;
2, be easy to move, can be used for different workplaces;
3, easy to use.

Wherein: the 1-fixing body; The 2-mounting hole of oil sprayer; The 3-observation panel; Mounting hole is taken in the 4-transition; The fastening screw of 5-fixing body; Gland nut is taken in the 6-transition.
Embodiment
In order to solve the technical problem in the existing oil sprayer detection, the utility model provides a kind of 4 air valve engine oil sprayer testing property frocks that are used for, comprise that oil sprayer, fixing body and transition take over fastening swivel nut, described fixing body is a hollow structure, be convenient to observe the identical situation of butt joint of oil sprayer and transition adapter and be convenient to adjust oil sprayer oilhole present position, and under the prerequisite that guarantees its rigidity, reduced and used material.Described fixing body can be fixed on the worktable by fastening screw.
As shown in Figure 1, the utility model frock is used for 4 valve oil sprayers and detects, and comprises fixing body 1 and transition adapter gland nut 6.Oil sprayer is installed on the mounting hole of oil sprayer 2 during test, and transition is taken over and to be installed in transition and to take over 4 li of mounting holes, by gland nut 6 it is compressed, and can observe the joint situation that oil sprayers and transition are taken over by observation panel 3 when mounted.Can frock be fixed on the worktable by the fastening screw of fixing body 5 in case of necessity.
Fixing body is according to the 100～300mm that is designed and sized to of oil sprayer and transition adapter, and gland nut 6 can be used motor assembling appliance, need not independent processing.
Described fixing body and fastening swivel nut are No. 45 common steel.
It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technological scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technological scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
