Description
Technical field
The present invention relates to diesel engine production field, more particularly to a kind of easy injection pump time adjusting device.
Background technology
At present, in domestic diesel engine production process, injection pump is typically necessary before being assembled on engine to be sprayed
Cam of injection pump axle is adjusted to the first cylinder beginning of injection position, then with the locked fuel injection camshaft of timing latch, so that it is guaranteed that starting
The fuel supply advance angle of machine is accurate.At present, injection pump timing regulation is strong using the instruments such as open-end wrench, flashlight, work mostly
Degree is big, and accuracy rate is not also high, and operating efficiency is low.Therefore, it is badly in need of a kind of efficient, accurate injection pump time adjusting device of design.
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 a kind of rational in infrastructure, effect
The easy injection pump time adjusting device that rate is high, accuracy is high.
To achieve the above object, a kind of easy injection pump time adjusting device of the invention, including disk, the disk
One plane is provided with adjustable gag lever post, is additionally provided with one handle at grade；Another plane of the disk is provided with
Disk is positioned at the alignment pin on camshaft outer face.
Further, the body of rod of the gag lever post is in flat, and its one end is provided with is locked at disk border by gag lever post
Lock-screw.
Further, described gag lever post is bending structure, in " Z " font.
Further, the size of the alignment pin is adapted with the size of the screw of camshaft outer face, the number of alignment pin
Measure as three.
Further, the handle is provided with the connecting rod that handle is connected with disk, and the connecting rod is vertically fixed on circle
The circle centre position of disk.
Beneficial effect
The structure of the present invention is simple, and reasonable in design, easily manufactured, cost is low；Rotated using handle operation of cam axle, it is time saving
It is laborsaving, reduce the labor intensity of worker；Gag lever post can rotate, and slewing area is wide, and device can be used for the oil spout of Multiple Type
Pump is adjusted, applied widely；Injection pump can quickly and accurately be adjusted just up to the first cylinder beginning of injection, it is simple to operate, during saving
Between, substantially increase operating efficiency.
Brief description of the drawings
Fig. 1 is the structural representation of the easy injection pump time adjusting device of the present invention.
In figure：1st, disk；2nd, gag lever post；3rd, handle；4th, alignment pin；5th, lock-screw；6th, connecting rod.
Embodiment
With reference to embodiment, the invention will be further described, but does not form any limitation of the invention, any
The modification for the limited number of time that people is made in scope of the invention as claimed, still in scope of the presently claimed invention.
Highly preferred embodiment of the present invention is such：Shown in reference picture 1, a kind of easy injection pump time adjusting device, bag
Disk 1 is included, a plane of disk 1 is provided with adjustable gag lever post 2, is additionally provided with one handle 3 at grade；Disk 1
Another plane is provided with the alignment pin 4 being positioned at disk 1 on camshaft outer face, size and the camshaft outer end of alignment pin 4
The size of the screw in face is adapted, and the quantity of alignment pin 4 is three, and disk 1 passes through alignment pin 4 and the screw of camshaft outer face
Positioning, on camshaft outer face, then by the rotation cam axle of handle 3, just staff's operation, time saving and energy saving, can drop
The labor intensity of low staff, the time is saved, improve efficiency.
In the present embodiment, the body of rod of gag lever post 2 is in flat, and its one end is provided with is locked at the edge of disk 1 by gag lever post 2
Lock-screw 5, elastic lock-screw 5 can by gag lever post 2 around locking locking 5 rotate, according to the position of different limit points
To adjust the position of gag lever post 2, simple in construction, the adaptability of intensifier, and gag lever post 2 is bending structure, in " Z " word
Shape, it is easy to gag lever post 2 to be contacted with the limit point on the inside of camshaft；Handle 3 is provided with the connecting rod 6 that handle 3 is connected with disk 1,
Connecting rod 6 is vertically fixed on the circle centre position of disk 1, handle 3 is not hindered the rotation of gag lever post 4, makes the rotation of gag lever post
Section is wider, and use range is wider.
From the above mentioned, by after each part manufacture of easy injection pump time adjusting device, assembling, it is also necessary to which device is directed to
The injection pump of a certain model is debugged.First, the injection pump of a certain model is selected, uses the instruments such as open-end wrench, flashlight
Injection pump timing is adjusted to the first cylinder beginning of injection position, now with the dead cam of injection pump of timing pin lock of injection pump at leisure
Axle；Then the disk 1 of device is positioned on the camshaft outer face of injection pump, selects suitable limit point, rotary spacing bar
2, gag lever post 2 is contacted with limit point, determine the angle of gag lever post, lock gag lever post 2.The easy spray of the injection pump of a certain model
Oil pump time adjusting device, which is just debugged, to be completed.
During actual use, according to the injection pump of different model, corresponding easy injection pump time adjusting device is chosen, by disk
1 is positioned on the camshaft outer face of injection pump, ensures the relative of easy injection pump time adjusting device and fuel injection camshaft
Position is unique, using the rotating circular disc 1 of handle 3 and camshaft, the gag lever post 2 on disk 1 is contacted with limit point, at this moment injection pump
Timing is just exactly at the first cylinder injection pump initial point position.The present apparatus can quickly and accurately adjust injection pump just up to first
Cylinder beginning of injection, it is simple to operate, the time is saved, substantially increases operating efficiency.
It the above is only the preferred embodiment of the present invention, it should be pointed out that for those skilled in the art, do not taking off
On the premise of from structure of the present invention, several modifications and improvements can also be made, these effects implemented all without the influence present invention
And practical applicability.
