Connect positioning tool.
Background technology
As shown in Figure 1 and Figure 2, high power alternator rotor is by being typically made up of axle 4, yoke 5, magnet steel 3, yoke 5 and
Magnet steel 3 is adhesively fixed on axle 4 using adhesive, because adjacent magnet steel 3 polarity is mutually exclusive, before adhesive is uncured, its
Repulsive force be more than bonding force, must apply during assembling pressure magnet steel 3 is fixed on axle 4 treat adhesive solidify.For realizing magnet steel
Bonding it is ensured that bonding quality and bonding efficiency, occur in that various adhesive positioning devices at present.
For example, the Chinese patent of Publication No. CN204089524U discloses a kind of magnetic steel of stator adhesive positioning device, bag
Include positioning disc, radial positioning cylinder and circumferentially positioned bar, described radial positioning cylinder is arranged on positioning disc, and setting circle
The centre of gyration of disk is overlapped with the centre of gyration of radial positioning cylinder；Described circumferentially positioned bar is arranged on positioning disc, and edge
The circumference of positioning disc is uniformly distributed.The radial positioning cylinder being arranged on positioning disc is stopped up with stator bearing and matches, permissible
Realize the positioning that positioning disc is with respect to the radial direction of stator；The centre of gyration and radial positioning cylinder due to positioning disc
The centre of gyration overlaps, and the radial distance of the therefore perisporium relative stator centre of gyration of positioning disc also determines that.But this device
Belong to magnetic steel of stator cemented in place, can only realize bonding magnetic steel in bore of stator.
For another example, the Chinese patent of Publication No. CN202971466U discloses a kind of spring non-magnetic matrix bonding magnetic steel dress
Put, offer the base of through hole, the sensor stand being arranged in base, the screw rod being arranged on base, screw rod including center
On top board, the nut being tightened on through screw thread on top board are installed；On screw rod between described top board and sensor stand
Spring is installed, rule is installed on the right side of spring；Described lower spring end is provided with pressure head, and described sensor stand upper end is installed
There is rubber blanket.This device pressure adjustable, adjusts the pressure between magnet steel and non-magnetic matrix, pressure by adjustment spring pressure
Size can be read it is ensured that magnet steel is not easily damaged in bonding process by rule, make the viscous of magnet steel and non-magnetic matrix
Connect effect and reach optimum state.But adhering device is only applicable to non-magnetic matrix bonding magnetic steel it is impossible to realize magnetic conduction matrix magnetic
Steel cemented in place.
And for example, the Chinese patent of Publication No. CN204921587U discloses one kind and glues by hold down gag, holds including magnet steel
Receive mechanism and hold-down mechanism, magnet steel holding mechanism includes the hollow cylindrical accommodating chamber that top is provided with opening, the top of accommodating chamber
Portion is provided with two curved baffles separately, and curved baffle is perpendicular with accommodating chamber and the two is structure as a whole, accommodating chamber
Top open part lid is installed, hold-down mechanism includes level table and pushes support located at the multiple of level table, this dress
Although put can reduce difficulty of processing, increase wage efficiency.But be only applicable to bonding magnetic steel on circular inner hole face it is impossible to
Realize the bonding of rotor outer circle face magnet steel.
In sum, existing bonding magnetic steel device is mostly only applicable to the bonding magnetic steel of servo-electric machine stator or non-magnetic
Matrix magnet steel glues, and magnet steel is to be bonded on circular inner hole face it is impossible to realize the bonding of rotor outer circle face magnet steel.
