Description
Technical field
The utility model relates to a kind of technological equipment, especially relates to a kind of dc brushless motor rotor segmentation dislocation frock.
Background technology
Dc brushless motor is in a lot of general application in the side of having, field, but use common rotor, the static moment of motor is relatively big, be 3S2P(3 groove 2 utmost points as the dynamo-electric machine in unit) structure, and this structure is relatively big for the static moment of motor, has a lot of methods can be used for reducing the static moment of motor, and rotor segmentation dislocation mounting structure is the method for relatively economical, simultaneously, rotor segmentation arranged in dislocation can also be improved motor running noises and vibration.At present, rotor segmentation arranged in dislocation is by ruling at rotor, relied on the dislocation angle of naked eyes control adjacent rotor then by the operator, the dislocation precision of adjacent rotor is difficult to control, if the angular error that staggers is bigger, can cause the decline of motor output torque, simultaneously the motor running noises is big, or energy imbalance is arranged and produces vibration, even motor occurs and scrap, reduce rate of finished products, improve production cost.Simultaneously, above-mentioned mounting means, not only the precision of rotor arranged in dislocation is difficult to guarantee, and production efficiency is lower, along with improving constantly of human cost, production cost also constantly improves.
The utility model content
The applicant has carried out research and has improved at above-mentioned problem, and a kind of dc brushless motor rotor segmentation dislocation frock is provided, simple in structure, easy to operate, the arranged in dislocation precision of adjacent rotor in guaranteeing to produce in batches, enhance productivity, improve rate of finished products, reduce production costs.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of dc brushless motor rotor segmentation dislocation frock, comprise patrix and counterdie, described patrix and counterdie are respectively cylindrical member and coaxial setting, the middle part of described patrix and counterdie is respectively equipped with the rotor containing hole, described counterdie is provided with two alignment pins, described patrix is provided with two dowel holes corresponding with the alignment pin on the described counterdie, and described alignment pin and described dowel hole are slidingly matched; Be respectively equipped with at least one positioning tooth in the containing hole of described patrix and counterdie, the misalignment setting of the center line of the positioning tooth of described patrix and the positioning tooth of described counterdie.
Further:
The dislocation angle of the center line of the center line of the positioning tooth of described patrix and the positioning tooth of described counterdie is between 5 ° ~ 15 °.
Be respectively equipped with two symmetrically arranged positioning tooths in the containing hole of described patrix and counterdie.
Technique effect of the present utility model is:
The disclosed a kind of dc brushless motor rotor segmentation dislocation frock of the utility model, simple in structure, easy to operate, utilize the positioning tooth of mutual dislocation in the upper and lower mould, the arranged in dislocation precision of adjacent rotor in guaranteeing to produce in batches, solve the inconsistent problem of the whole static moment of motor in the batch production process, reduce the static moment of motor, the motor running noises is little, the vibration that reduces energy imbalance and produce, enhance productivity, improve rate of finished products, reduce production costs.
