The purpose of the embodiment of body, it is not intended that in the limitation present invention.Term as used herein " and/or " including one or more phases
The arbitrary and all combination of the Listed Items of pass.
As shown in Figs 1-4, the present invention provides a kind of drive system housing production technology, specifically includes following steps：
Step S10, prefabricated electric machine casing 10 and reduction box casing 30.
Specifically, by the prefabricated electric machine casing 10 of die-casting process and reduction box casing 30, by electric machine casing 10 and reduction box
Housing 30 casts to obtain by two molds respectively.With mold when traditional integrally casting electric machine casing 10 and reduction box casing 30
It compares, the mould structure used in the prefabricated electric machine casing 10 of difference and reduction box casing 30 is relatively simple, and die cost is relatively low, raw
It is higher to produce efficiency.
Step S30 docks electric machine casing 10 and reduction box casing 30 and forms total housing 100, that is, is obtained prefabricated
Electric machine casing 10 and reduction box casing 30 are directly to being connected in an entirety.
Step S30 specifically includes step S32, step S34 and step S36.
Step S32, the first interface 12 of preprocessing electric machine casing 10, the second interface of preprocessing reduction box casing 30
32.It so avoids the first interface 12 and the second interface 32 uneven, ensures the first interface 12 and the second interface 32
Flatness.
Step S34 makes the first interface 12 and the second interface 32 overlap.Because the of 12 sum of the first interface
Two interfaces 32 have been subjected to preprocessing processing, and can overlap stacking, be assembled.
Step S34 specifically includes step S341 and step S343.
Step S341, preprocessing positioning spigot 34, another one on one of electric machine casing 10 and reduction box casing 30
The cooperation position (not shown) that upper preprocessing coordinates with positioning spigot 34.
Positioning spigot 34 is set in cooperation position, while overlaps the first interface 12 and the second interface 32 by step S343.
By positioning spigot 34 and the cooperation of cooperation position, position when the first interface 12 of limitation and the second interface 32 overlap,
Ensure that the first interface 12 and the second interface 32 accurately overlap.
In this specific embodiment, positioning spigot 34 is set on reduction box casing 30, and cooperation position is set on electric machine casing 10.It can
To understand ground, in some other embodiment, positioning spigot 34 and cooperation position can also be respectively arranged on electric machine casing 10 and slow down
On tank shell 30, position when the first interface 12 and the coincidence of the second interface 32 can be positioned, is not limited herein.
Step S36 connects electric machine casing 10 by connector 50 and reduction box casing 30 forms total housing 100.By first
After 12 and second interface 32 of interface overlaps, electric machine casing 10 and reduction box casing 30 are connected by connector 50, make motor
Housing 10 and reduction box casing 30 are integrated into an entirety, i.e., total housing 100.
Specifically, connector 50 is bolt, and electric machine casing 10 and reduction box casing 30 is bolted.It is appreciated that
Ground in some other embodiment, can also connect electric machine casing 10 and reduction box casing 30, for connection by connecting plate etc.
The concrete structure of part 50 does not limit herein, can connect electric machine casing 10 and reduction box casing 30.
Step S50 finishes the assembly space in total housing 100.Assembly space include bearing chamber, oil sealing position and
Iron core shelves finish bearing chamber, oil sealing position and the iron core shelves in total housing 100.Namely to the weight in total housing 100
Size is wanted to be finished, ensures the precision of the components such as subsequent installation rotor, reduction gearing.Specifically, bearing chamber includes
It is located at rotor bearing room and reduction gearing bearing room in electric machine casing 10 and reduction box casing 30 respectively, to total housing
Rotor bearing room and reduction gearing bearing room in 100 are finished, and are ensured in rotor bearing room and reducing gear
Wheel bearing room is installed by precision during bearing.
Further, step S50 specifically includes step S52 and S54.
Step S52, the total housing 100 of clamping, can fixing motor housing body simultaneously by the total housing 100 of fixture clamped one time
10 and reduction box casing 30.
Step S54, selected reference axis, and the assembly space in total housing 100 is finished according to Geometrical Tolerance Principle.Also
It is to say, in the assembly space in finishing total housing 100, is processed by unified reference axis, electric machine casing 10 and is subtracted
Fast tank shell 30 processes important fit dimension with same reference axis.It first processes electric machine casing 10 respectively compared to tradition and subtracts
The technical solution that the significant dimensions of fast tank shell 30 are assembled again, using the side for carrying out finishing significant dimensions after assembling again
Method, can unify the machining benchmark of electric machine casing 10 and reduction box casing 30, and eliminates in conventional solution and assembled after processing
When can not be assembled to the completely the same error brought because of the machining benchmark of electric machine casing 10 and reduction box casing 30, improve total shell
The machining accuracy of body 100.
In above-mentioned drive system production technology, first prefabricated electric machine casing 10 and reduction box casing 30, then by electric machine casing
10 and reduction box casing 30 docking form total housing 100, then the assembly space in total housing 100 is finished.Due to being
Total housing 100 after assembling is finished, whole process only needs clamped one time, processes electric machine casing 10 and slows down
The benchmark of tank shell 30 is identical, ensures the precision of 30 mutual cooperation size of electric machine casing 10 and reduction box casing, assembles production
Precision is improved significantly, and improves the overall performance of drive system.Meanwhile electric machine casing 10 and reduction box casing 30 are distinguished
It carries out prefabricated, does not need to be whole to total housing 100 and cast, mould structure is relatively simple, and production efficiency is higher.In this way, just
The design requirement that mold is simple in drive system housing production technology and precision is higher can be taken into account.
Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, it is all considered to be the range of this specification record.
Embodiment described above only expresses the several embodiments of the present invention, and description is more specific and detailed, but simultaneously
It cannot therefore be construed as limiting the scope of the patent.It should be pointed out that those of ordinary skill in the art are come
It says, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the protection of the present invention
Range.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
