Description
Technical field
The present invention relates to a kind of diesel engine assembly tool, more specifically, it relates to which a kind of diesel injector oil spout carries
Preceding angle assembly tool.
Background technology
In diesel engine assembling, the fuel injector injection advance angle of diesel engine has a variety of setting angles, such as：8°、
10 °, the kinds more than ten such as 12 °, it can not guarantee its precision without applicable frock, prewired fuel injection pump gear angle at present.Due to lacking
It is few it is a kind of can directly pre-assigned diesel injector injection advance angle frock, it is difficult to fill in assembling process to cause diesel engine
The fuel injector injection advance angle of diesel engine is prepared, therefore the oil spout of diesel engine must be readjusted during diesel engine Thermal test
Device injection advance angle, needing during concrete operations to dismount the diesel engine parts such as gear chamber cover plate, workload is big, not only influences production,
Also result in loss economically.
The content of the invention
The technical problem to be solved in the present invention is the above-mentioned deficiency for prior art, there is provided it is a kind of rational in infrastructure, make
Simple diesel injector injection advance angle assembly tool, effectively improves production efficiency, saves financial cost.
It is the technical scheme is that such：A kind of diesel injector injection advance angle assembly tool, including bottom
Plate, it is characterised in that be fixed with idle gear on described bottom plate, installation oil pump gear is provided with the bottom plate on the outside of idle gear and is connected
The locating shaft of device is connect, locating shaft is flexibly connected with bottom plate, and described locating shaft is provided with adjustment handle；Bottom plate in locating shaft periphery
Datum hole is provided with, is provided with multiple angle positioning holes on the bottom plate of datum hole periphery, the deflection angle of the locating shaft passes through
The latch for being plugged on angle positioning hole and adjusting between handle is fixed.
It is preferred that described bottom plate is provided with multiple supporting screw holes, adjustment handle is located at the two of bottom plate respectively with locating shaft
Side.
It is preferred that described multiple angle positioning holes are on the circular arc using locating shaft as the different radii of pivot.
It is preferred that described multiple angle positioning holes are located on the circular arc of three different radiis, each angle positioning hole pair
Answer the deflection angle of a locating shaft.
It is preferred that bearing is provided between described locating shaft and bottom plate.
It is preferred that the idle gear is fixed on bottom plate by briquetting and screw.
Compared with prior art, diesel injector injection advance angle assembly tool of the invention, can be according to diesel engine
Technological requirement pre-assigned injection pump degree of advance, avoid carrying out injection pump advance angle in Thermal test readjusting, not only
Solve the problems, such as low production efficiency, while also improve the uniformity and reliability of product, greatly reduce production cost.
It will be become more fully apparent by following description and with reference to accompanying drawing, the present invention, these accompanying drawings are used to explain the present invention
Embodiment.

Embodiment
Embodiments of the invention are described with reference now to accompanying drawing, similar element numbers represent similar element in accompanying drawing.
As shown in Figures 1 to 5, the diesel injector injection advance angle assembly tool includes bottom plate 1, the and of idle gear 4
Adjust handle 7.
Its bottom plate 1 is provided with the locating shaft 2 of installation oil pump gear connector, and the locating shaft 2 passes through bearing 3 and bottom plate
1 connection, for supporting the operation that is located by connecting of assembling oil pump gear connector and oil pump gear.
Supporting screw hole 13 on the side of bottom plate 1 four is bolted the whole diesel injector injection advance of fixed bearing
Angle installation tool.
Benchmark of the datum hole 11 that bottom plate 1 is provided with as angle positioning hole 12, the multiple angles positioning being distributed on bottom plate 1
Hole 12 provides different deflection angles for oil pump.
Idle gear 4 is fixed on bottom plate 1 by pressing plate 5 and screw 6, and it is that installation is relatively fixed oil pump gear, so as to really
The angle of stand oil pump gear.
Adjustment handle 7 is rotated centered on locating shaft 2, is distinguished by latch and multiple angle positioning holes 12 on bottom plate 1
Coordinate, fixed corresponding angle.
During concrete operations, by the requirement according to oil pump angle of assembling, adjustment handle 7 is rotated, is made on angle adjustment handle 7
Positioning hole 71 and the selected face of bottom plate angle positioning hole 14, and plug latch；Then oil pump gear connector is placed on positioning
On axle 2, and the keyway of oil pump connector is fallen into being good for for locating shaft 2, oil pump gear is placed on oil pump connector, simultaneously
Make the mark of oil pump and the mark face of idle gear 4, then fixed oil pump connector and oil pump gear with screw.In installation oil
During pump, the key of oil pump is inserted on oil pump connector, the mark of idle gear 4 on the mark and diesel engine of oil pump gear is just
It is right, you can to complete the assembling of fuel injection advanced angle pair, and the effect of " one trues up " can be reached.
Above in association with most preferred embodiment, invention has been described, but the invention is not limited in implementation disclosed above
Example, and modification, equivalent combinations that the various essence according to invention are carried out should be covered.
