Description
Technical field
The present invention relates to assembling die technical fields, more specifically to a kind of magnetic shoe quick assembling of field frame assembly
Method.
Background technique
Stator is motor or the stationary part of starter.Stator is by stator core, stator winding and three, base
It is grouped as.The main function of stator is to generate rotating excitation field, and the main function of rotor is to be cut in rotating excitation field by the magnetic line of force
Undercutting and generate electric current.
Currently, most of field frame assemblies are made of stator casing, magnetic shoe and magnetic shoe folder, partial stator is directly by stator casing
And magnetic shoe composition, it is equipped with the magnetic shoe that muti-piece presses even circumferential distribution in the inside of stator casing, magnetic shoe is secured at stator casing
Inner surface.For traditional tooling when carrying out magnetic shoe stickup, efficiency is lower.Especially there is the stator of multi-disc magnetic shoe in needle same direction
Assembly causes sticking efficiency lower due to the installation accuracy of magnetic shoe to be guaranteed.Therefore, how the completion of high efficiency, high quality is determined
Subshell and magnetic shoe are coupled, its development is particularly important.
Chinese patent discloses a kind of generator amature assembly tooling, and (application number: 201420777272.8) including preceding annular
Baffle, four isolating bars being circumferentially uniformly fixed on ring baffle and the rear annular gear being connect with isolating bar detachable
Plate further includes semi-circular partition, is provided on the inner arc surface of the semi-circular partition and is engaged by clamping with isolating bar detachable
Rectangle card slot.The utility model generator amature assembly tooling, when assembly, first first cover tooling on the iron core of rotor, then
Peace side's rotor magnetic shoe between adjacent isolating bar again can avoid adjacent magnetic shoe in magneticaction due to the buffer action of isolating bar
Lower offset dislocation, so as to the assembly tooling efficiency of very big raising generator amature.
Above-mentioned patent formula is the installation that multi-disc magnetic shoe is carried out on stator, illustrates structure when magnetic shoe laid out in parallel,
But it is not used to the assembly of the magnetic shoe on stator.
In addition, Chinese patent also disclose it is a kind of for magnetic shoe to be assemblied in casing inner wall jig (application number:
201721251855.7), including positioning unit and support unit；The positioning unit is for carrying casing and magnetic shoe；The branch
Support unit is used to apply pressure to the magnetic shoe along the radial direction of casing.Due to using positioning unit and support unit collective effect, to magnetic
Watt positioning assembly is carried out, the motor production process especially suitable for the more specifications of small lot.
Above-mentioned patent formula is magnetic shoe assembly method more traditional at present, due to only a piece of on same axial direction
Magnetic shoe, even if not being very big to entire effect there are error；But it can not be directed to the installation of multi-disc magnetic shoe, and its structure determines
Installation effectiveness is lower, is merely able to assemble for the magnetic shoe of small lot.
