Abstract
The utility model discloses a special mould for a motor rotor and an air gap between the rotor and a stator, which comprises a rotor slot male mould and a female mould, wherein the female mould is matched with the rotor slot male mould, and the punch top of the rotor slot male mould is connected with an air gap punch. In the utility model, because the punch top of the rotor slot male mould is connected with the air gap punch, in the blanking processes of the rotor and the stator, the stator slot is punched first by the stator slot male mould; during punching, the edge is cut simultaneously to obtain a stator punching sheet and a round steel disc of which the diameter is equal to the outer diameter of the air gap; and then the special mould for the rotor slot and the air gap thereof is used for punching the rotor slot and the air gap thereof, and the edge equal to the air gap in width is cut off simultaneously when the rotor slot is punched. The utility model has the advantages of high production efficiency, good product quality, low labor intensity of operators and low production cost.
Description
Technical field:
The utility model relates to field of motor manufacturing, is specifically related to the rotor of motor and air gap processing method and the particular manufacturing craft thereof between rotor and the stator.
Background technology:
As everyone knows, air gap need be left in the middle of the stator of motor and the rotor, the operate as normal of stator, rotor can be guaranteed.At present, the air gap part in the middle of stator and the rotor is in the motor stamping blanking it to be dropped on the rotor punching, treats to go up after rotor is carried out lathe again its redundance (being the air gap part) car is fallen.Process the middle air gap of stator and rotor in this way and exist following defective: the one, for the rotor of big external diameter, just need process with bigger lathe equipments, cause equipment to have high input, increase unnecessary expenditure to enterprise; The 2nd, rotor surface is after processing, and surperficial punching meeting is linked together, can produce eddy current loss like this; The 3rd, the air duct periphery after the processing can produce a lot of burrs, and cleaning is difficulty very; The 4th, after the rotor surface processing, rotor is high can be inconsistent, the deviation theory calculated value.
Summary of the invention:
The technical problems to be solved in the utility model provides the particular manufacturing craft of air gap between a kind of rotor and rotor and the stator, overcomes the defective of prior art.Another technical problem to be solved in the utility model provides the preparation method of air gap between rotor and rotor and the stator.
The utility model is achieved through the following technical solutions:
The particular manufacturing craft of air gap between rotor and rotor and the stator comprises the rotor punch, and with the die of rotor punch coupling, the drift top of described rotor punch is connected with the air gap drift.
The further improvement project of the utility model is, described air gap drift one side lower part is connected in rotor drift top, this side overlaps with the same side line stretcher in rotor drift top, its limit, lower end is from the opposite side edge at rotor drift top, extend to this side with radian with rotor, and the chord length of extending camber line equals the wire length between the two adjacent rotor adjacent edge tops or equals two adjacent rotor with the wire length between the top on one side.
The utility model further improvement project is, described air gap lower portion of ram any part is connected in rotor drift top, limit, lower end, both sides from the dual-side at rotor drift top along, extend to both sides with radian with rotor, the chord length of both sides extension camber line equals the wire length between the two adjacent rotor adjacent edge tops.
The utility model further improvement project is, described air gap drift is circular, and inner rim is connected in each rotor drift top, and the width of air gap drift is wider than width of air gap.This design is multiple punch die structure, and the rotor punch once falls, and the rotor and the air gap of rotor periphery once can be finished.
The utility model is in order to strengthen the intensity of particular manufacturing craft, and the 5-20 that described air gap drift width is a width of air gap doubly.
Prepare the method for air gap between rotor and rotor and the stator with above-mentioned particular manufacturing craft, comprise the following steps:
(1) to the round tablet that cut, be the round steel sheet that its diameter equals stator outer diameter, with the stator slot punch stator grooved is gone out earlier, trimming side cut in limit obtains the round steel sheet that stator punching and diameter equal the air gap external diameter when dashing;
(2) diameter that step (1) is obtained equals the round steel sheet of air gap external diameter, with rotor and air gap particular manufacturing craft red switch pilot trench and air gap thereof, cuts away the limit that equals width of air gap in the time of the red switch pilot trench, obtains rotor punching;
(3) rotor punching that step (1) is obtained is laminated in the rotating shaft, then copper bar is squeezed into rotor, or rotor coil is inserted rotor gets final product.
The utility model compared with prior art has following obvious advantage:
The utility model is connected with the air gap drift at rotor punch top, in rotor, stator blanking process, with the stator slot punch stator grooved is gone out earlier, the limit trimming is cut edge when dashing, obtain the round steel sheet that stator punching and diameter equal the air gap external diameter, and then with rotor and air gap particular manufacturing craft red switch pilot trench and air gap thereof, the limit that equals width of air gap is cut away on limit red switch pilot trench, limit.
From as can be known above-mentioned, though the utility model will partly drop on the rotor punching by air gap, but in red switch pilot trench process, by the air gap drift (being air gap) cut away on unnecessary limit, not only have production efficiency height, good product quality, advantage that operator's labour intensity is little, and need not to purchase bigger lathe equipments, and can realize rotor processing to the arbitrary dimension external diameter, can effectively save the production cost of enterprise.
