It is all because of the made dovetail groove parameter of Traditional Method that present invention consideration tradition work circle, which finds intersection and makes the deficiency of trapezoidal channel process,
It is not consistent with ideal dovetail groove parameter, therefore proposes to find intersection the ideal dovetail groove armature stamping method of system as parallel lines, with such side
The made dovetail groove parameter of method is consistent completely with ideal dovetail groove parameter.
The technical scheme is that a kind of method of dovetail groove armature stamping processed, includes the following steps:
Step 1. enables circular diameter in armature stamping based on the final ideal dovetail groove parameter of Ansoft calculating gained respectively
For φ a, outside diameter is φ b, and is justified respectively with φ a, φ b work, remakes center line A, B right-angled intersection in point O；
A center line is replicated 10 ° of rotation using O as basic point by step 2. clockwise, obtains C line, hands over the circle of φ a in point u；With
Bs0/2 is that width makees C line parallel lines D, hands over φ a circle in v point；Make A line parallel lines E and F respectively with Bs1/2 and Bs2/2；And it puts down
Line E, F are located at the same side of A line, and D line is between A line and E line, and F line is between E line and C line；
Step 3. is line segment vm=Hs0 along D line using v point as starting point, and m point is on the outside of φ a circle, then by point m to make B line parallel
Line G；Make G line parallel lines J, K, L by spacing of Hs0+Hs1, Hs0+Hs1+Hs2 and Hs0+Hs1+Hs2+Rs respectively along D line, wherein
J line hands over E line in n point, and K line hands over F line in x point, and L line hands over A line respectively at y point；Be sequentially distributed from lower to upper above B line G line, J line,
K line and L line；
Step 4. makees the chamfering of L line Yu F line, and connecting line segment mn, nx with Rs；Retain camber line uv, punching outer circle φ b, in
Heart line A, B and vmnxy line, deletes remaining line；
Step 5. is using A line as center line, to vmnxy line mirror image, then using O as basic point, carries out to vmnxy line and its image line
Array finally obtains and ideal dovetail groove parameter；Wherein:
Bs1 is the slot wedge maximum width of armature stamping；
Bs2 is the groove body bottom width of armature stamping；
Hs0 is the channel opening height of armature stamping；
Hs1 is the slot wedge height of armature stamping；
Hs2 is the groove body height of armature stamping；
Rs is the groove body bottom chamfer of armature stamping.
The invention has the advantages that the present invention will be to find intersection dovetail groove armature stamping method substitution tradition system ladder processed as parallel lines
Shape slot armature stamping method can reduce motor copper factor and thermic load, shorten the motor lead time, and improve motor operation effect
Rate.
Detailed description of the invention
The invention will be further described with reference to the accompanying drawings and embodiments:
Fig. 1 is to calculate resulting final ideal dovetail groove parameter described in step 1 with Ansoft；
Fig. 2 is the result figure of step 1；
Fig. 3 is the result figure of step 2 and step 3；
Fig. 4 is the result figure of step 4；
Fig. 5 is the result figure of step 5.
Specific embodiment
Embodiment: by taking certain model unmanned plane rudder motor as an example, in conjunction with shown in FIG. 1 to FIG. 5, elaborate that tradition is made to justify
