Fig. 1 is the top view of oil pump cover provided in an embodiment of the present invention, as shown in Figure 1, oil pump cover provided by the invention, bag
Lid main body 100 is included, location division is provided with the lateral surface of the lid main body 100, location division is used for the press fitting in case of transmission
Positioned in journey.The quantity of location division is multiple, and positioning surface 200, and the positioning surface of multiple location divisions are provided with location division
200 in the same plane.Positioning surface 200 is parallel with the medial surface of the lid main body 100, and oil pump cover is being worked into speed changer
When on housing, the support column 300 on oil pump assy fixture is supported on the positioning surface 200 of oil pump cover, because multiple location divisions
Positioning surface 200 in the same plane, so oil pump assy fixture towards where case of transmission direction move when, can be by oil
Pump cover is accurately assemblied on case of transmission, and oil pump assy will not produce crooked, guarantee press fitting quality when being pressed.
Oil pump assy is positioned to accurately on press, it is impossible to produces deviation, comprehensive analysis design drawing, by black skin and outside
Shape influences, and no suitable location point, prior art kind can only be taken to be positioned with the outer rounded corner of oil pump, this technological requirement workpiece
Cylindrical and chamfer machining uniformity it is fine, press fitting speed is slow, causes process for machining cumbersome, is not easy to ensure size, presses
It is slow to fill efficiency, beat length, and the gearbox of above-mentioned positioning method press fitting, oil pump assy occur inclined phenomenon, have impact on
Production efficiency, reduces the quality of product.
A kind of scheme kind that can implement, multiple location divisions are arranged on same circle, and are centered around the oil pump cover
On the outside of axis hole.When being positioned by support column 300 to oil pump cover, positioning surface 200, which is uniformly distributed, can increase the accurate of positioning
Property.
According to 3 points of principles for determining a plane, the quantity of location division can be at least 3, setting in this way,
It can achieve the purpose that the stable oil pump cover that supports, meanwhile, process enhanced convenience.
Preferably, the quantity of the location division is 5, according to the surface area of existing oil pump cover, set location division for 5
It is a, can preferably it be distributed on the surface of oil pump cover.
In the scheme that one can implement, the area of positioning surface 200 can be more than the support of the oil pump assy fixture
The area of 300 end face of column.In the design of oil pump cover and oil pump assy fixture, the area of positioning surface 200 be able to can be more than
The area of 300 end face of support column of the oil pump assy fixture, so when oil pump cover is placed on oil pump assy fixture, branch
The end face of dagger 300 can preferably contact and be supported on positioning surface 200, the other structures without touching oil pump cover, example
Reinforcing rib is touched as unexpected, and the assembling speed of oil pump cover and oil pump assy fixture is faster.
In the scheme that one can implement, the outside direction that location division includes the lateral surface to the lid main body 100 prolongs
The cylindrical boss stretched, the cylindrical boss is multiple, and is corresponded with the positioning surface 200, and the positioning surface 200 is located at institute
State on the end face of cylindrical boss.Cylindrical boss is processed on present oil pump cover material, on the one hand, in process, is first processed
Go out cylindrical boss, then face is gone to process the other parts on oil pump cover, Ke Yibao on the basis of the positioning surface 200 in cylindrical boss
It is more accurate to demonstrate,prove the oil pump cover structure processed；Another side, cylindrical boss protrude from 100 surface of lid main body, are positioning
When, it can be easier to abut with support column 300, position from the influence of other structures in lid main body 100.
Fig. 2 is the flow chart of the processing method of oil pump cover provided in an embodiment of the present invention, as shown in Fig. 2, the present invention provides
Oil pump cover processing method, including step：Preliminary working is carried out to raw material first, multiple columns are processed on the side of raw material
Location division, the length of multiple location divisions is identical, and the outer end face of the location division is positioning surface 200, and multiple location divisions
Positioning surface 200 in the same plane；Then, raw material is reprocessed, with the plane where multiple positioning surfaces 200
On the basis of plane machining oil pump cover remaining structure.That is, the location structure of the oil pump cover is put down using multiple positioned at same
The positioning surface 200 in face, without the chamfering structure before use, reduces difficulty of processing, while improves positioning accuracy, compares
Positioned in chamfering, plane positioning can prevent the crooked phenomenon of the oil pump cover occurred during press fitting.Meanwhile added using above-mentioned
Work mode, first processes columnar location division, then using location division processing oil pump cover and thereon remaining ruler of other structures in itself
It is very little, during the work first if fixed next datum level, the structure of oil pump cover that processes can be made more accurate.

Pump assembly fixture, the oil pump assy fixture are used to fix above-mentioned oil pump cover.It is corresponding, including with the location division one on oil pump cover
One corresponding support column 300.The supporting surface of multiple support columns 300 in the same plane, is used to support in the oil pump
Cover on corresponding positioning surface 200, it is ensured that after the oil pump cover of oil pump assy is placed on oil pump assy fixture, support column
300 are supported on positioning surface 200, complete precise positioning, oil pump assy fixture is moved to case of transmission again, by oil pump assy pressure
It is attached on case of transmission, oil pump assy will not produce crooked, guarantee press fitting quality.
In the scheme that one can implement, the area of the supporting surface of the support column 300, which is less than on the oil pump cover, to be determined
The area of plane 200.So when oil pump cover is placed on oil pump assy fixture, the end face of support column 300 can be more preferable
Contact is supported on positioning surface 200, the other structures without touching oil pump cover, the assembling of oil pump cover and oil pump assy fixture
Speed is faster.
Speed changer assembly equipment provided by the invention, including gear box casing fixture, the first driving mechanism, the second driving machine
Structure and above-mentioned oil pump assy fixture.Gear box casing fixture is arranged on the top of oil pump assy fixture, and the first driving mechanism is used
In driving the gear box casing fixture, gear box casing is transported to the surface of oil pump assy fixture.Second driving mechanism
For driving the oil pump assy fixture to be fitted in the oil pump assy towards direction movement where the gear box casing
On the gear box casing.Using above-mentioned oil pump assy fixture, oil pump assy will not produce crooked, guarantee press fitting matter when being pressed
Amount.
First driving mechanism and the second driving mechanism can include hydraulic device and servomotor, can smoothly drive folder
Tool movement.
Finally it should be noted that：Embodiment described above, is only the embodiment of the present invention, to illustrate the present invention
Technical solution, rather than its limitations, protection scope of the present invention is not limited thereto, although with reference to the foregoing embodiments to this hair
It is bright to be described in detail, it will be understood by those of ordinary skill in the art that：Any one skilled in the art
