Description
Technical field
The present invention relates to field of tooling equipment, more particularly, to a kind of applied to permanent magnet machine rotor SmCo alinco assembled
Device and method.
Background technique
The common structure of permanent magnet machine rotor is rotor core 7 plus magnet steel 20 as shown in Fig. 1, using different materials
Magnet steel brings differing greatly for motor performance.Permanent magnet machine rotor permanent-magnet material generally uses neodymium iron boron magnetic body or other permanent magnetism materials
Material, the magnetic property of NdFeB material is not so good as samarium-cobalt material, but their mechanical performance is better than samarium-cobalt material, therefore for big
The high performance magneto of power generally uses high performance SmCo magnet steel.It is assembled in permanent magnet (magnet steel 20) and rotor core 7
When, since permanent magnet is ferromagnetic material, and rotor core 7 is high permeability material, and permanent magnet will be packed into magnetic slot (rotor core
Slot) 5 without being very difficult to using the positioning of dedicated guiding device to be fitted into.Enter the magnetic slot 5 of magnetic conduction in permanent magnet
The magnetic flux of rotor core 7 is set to change in the process, therefore permanent magnet will generate a magnetic thrust in rotor core 7 and push
Permanent magnet moves in magnetic slot 5.If the gap that permanent magnet enters 5 periphery of magnetic slot is uniform, the weight of magnetic thrust and permanent magnet
Power direction is consistent, and permanent magnet can not cannot stop in magnetic slot 5 by other resistance., whereas if permanent magnet and rotor iron
Core slot peripheral clearance is uneven, then permanent magnet can be in the lesser one side in gap by absorption.In addition, in magnetic slot 5 it is adjacent forever
Magnet can be mutually exclusive, without attracting each other, as long as therefore control permanent magnet first mounting distance rotor core 7 it
Outside, then assembling other permanent magnet would not cause permanent magnet to generate breakage because mutually colliding.
Since SmCo magnet steel has the mechanical performance also more frangible than glass (bigger than other magnet steel fragilities), in magnet steel 20 and turn
Guarantee that its integrality is a great problem in the assembly overall process of sub- iron core 7.In the prior art, other in addition to SmCo magnet steel
Alinco assembled generally uses vertical assembly method as shown in Fig. 1, and if I show 20 approach axis of magnet steel in attached drawing, U is magnetic
The thickness of steel 20.The top of rotor core 7 is provided with magnet steel guided mode 18, and the lower part of rotor core 7 is provided with baffle 8.This side
Formula is assembled from the open at one end of magnetic slot 5, magnet steel 20 is pushed into magnetic slot 5 by push rod 16, if it is manual assembly
Only need people assembly.And common SmCo manual assembly method, it is using horizontal assembly method as shown in Fig. 2, this method
It is operated using two people, the both ends all-pass of magnetic slot 5, alinco assembled overall process is retreated to synchronize and be carried out, if retreat operation is asynchronous
Magnet steel is frangible, and horizontal can only assemble, low efficiency.
As shown in Fig. 2, common magnet steel guided mode 18 can only control magnet steel 20 and enter slot, and magnet steel 20 enters slot distance by two people
Simultaneously operating control, if A show operator's direction of retreat in attached drawing 2, as B show 20 approach axis of magnet steel in attached drawing.
Rotor core 7 is horizontal to be placed on workbench, and a people is turned the push-in of magnet steel 20 using push rod 16 in one end of magnet steel guided mode 18
The distance of sub- 7 one magnet steel 20 of iron core, the operator of the other end give certain thrust guarantee threading every using bar 17 is moved back
Magnet steel 20 rests on same position, two advance and retreat simultaneously operatings, and otherwise magnet steel 20 is a piece of under walking biggish distance in the core and making
Magnet steel 20 damages when assembling.
As shown in Fig. 3, it is schematic illustration using SmCo magnet steel magnetic holder assembly method, as C show and pushes away in attached drawing 3
Force mechanisms reinforce direction.Magnet steel 20 in 7 one magnetic slots 5 of rotor core is mounted in non-magnetic magnetic holder 21 by this method in advance,
Mutually exclusive between magnetic links (magnet steel 20), magnetic holder 21 is positioned by locating rod 1, locating rod 2 22 and magnetic slot 5.Using
Several pieces 20 entirety of magnet steel in same slot after, are pressed into rotor cores 7 by the magnet steel 20 in magnetic holder 21 by dedicated thrust mechanism
In.Locating rod 1 and locating rod 2 22 are connected into an alinco assembled mechanism by push rod 16, when guaranteeing that magnet steel 20 enters magnetic slot 5
It retreats and synchronizes, to guarantee that not impaired (because 20 repulsive forces of magnet steel are big, the length of magnetic holder 21 need to be greater than 3 to 20 assembling process of magnet steel
Times or more the length of rotor core 7 could will be under 20 row of magnet steel of whole slot).But this alinco assembled apparatus structure is complicated, specially
Thrust mechanism need to overcome the summation of all 20 repulsive forces of magnet steel in same slot, and thrust when assembling magnet steel 20 is larger.Meanwhile this
The magnetic holder length of kind SmCo magnet steel magnetic holder assemble mechanism is the three times of 5 length of magnetic slot or more, and press-mounting stroke is than general stroke
Also big 3 times or more are wanted, automatic assembling mechanism is made to become huge.
Therefore, the alinco assembled mode of the prior art is primarily present following technological deficiency：
(1) traditional artificial horizontal assembly method, although can control magnet steel enters the distance after iron core slot, magnetic slot
Structure design has a limitation, magnetic slot 5 must both ends connection, when no assembling device special must two people's simultaneously operatings, adjacent two pieces
Magnet steel enter magnetic slot before by repulsive force rather than attraction, magnet steel is pressed by magnetic slot by external force, work efficiency is lower, magnetic
Steel can assembly be damaged, and product qualification is low, if one man operation, alinco assembled breakage rate be will be up to because the nonsynchronous factor of people generates
50% or more；
(2) traditional artificial magnetic holder assembly method, single non-magnet material production, can only in alinco assembled from correcting
Effect cannot carry out eccentric assembling to magnet steel, and it is big and uncontrollable that magnet steel enter rotor core slot stroke, and magnetic holder is pushed away using dedicated
Although can guarantee that alinco assembled overall process is not damaged into mechanism, alinco assembled mechanism is 4 times of core length or more, mechanism
Complicated huge, every slot assembly positioning operation is complicated, is unfavorable for the small lot production of product.When same slot piece alinco assembled free walker
Journey be greater than entered magnetic slot magnet steel between guide plate at a distance from, then adjacent two panels magnet steel will collide, because SmCo magnet steel shock resistance is strong
Spend low, the magnet steel that thus assembles can be therefore damaged.
