Description
Technical field
The present invention relates to a kind of rotor magnetic steel adhesive positioning device, particularly relate to a kind of rotor same polarity bonding magnetic steel fixed
Position device.
Background technology
As shown in Figure 1 and Figure 2, high power alternator rotor by being typically made up of axle 4, yoke 5, magnet steel 3, yoke 5 and
Magnet steel 3 uses adhesive to be adhesively fixed on axle 4, owing to adjacent magnet steel 3 polarity is mutually exclusive, before adhesive is uncured, its
Repulsive force is more than bonding force, must apply pressure and be fixed on axle 4 by magnet steel 3 and treat that adhesive solidifies during assembling.For realizing magnet steel
Bonding, it is ensured that bonding quality and bonding efficiency, occur in that various adhesive positioning device at present.
Such as, the Chinese patent of Publication No. CN204089524U discloses a kind of magnetic steel of stator adhesive positioning device, bag
Including positioning disc, radially positioning cylinder and circumferentially positioned bar, described radial direction positioning cylinder is arranged on positioning disc, and setting circle
The centre of gyration of dish overlaps with the centre of gyration of radially positioning cylinder；Described circumferentially positioned bar is arranged on positioning disc, and edge
The circumference of positioning disc is uniformly distributed.The radial direction positioning cylinder being arranged on positioning disc stops up with stator bearing and matches, permissible
Realize the positioning disc location relative to the radial direction of stator；The centre of gyration and radially positioning cylinder due to positioning disc
The centre of gyration overlaps, and therefore the radial distance of the 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 be installed, be tightened on the nut on top board through screw thread；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, regulates the pressure between magnet steel and non-magnetic matrix, pressure by adjusting spring pressure
Size can be read by rule, it is ensured that magnet steel is difficult to impaired in bonding process, makes 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 a kind of viscous by hold down gag, holds including magnet steel
Receiving mechanism and hold-down mechanism, magnet steel holding mechanism includes that top is provided with the hollow cylindrical accommodating chamber of 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 include level table and be located at level table multiple under press support, this dress
Can reduce difficulty of processing although putting, increase wage efficiency.But it is 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.
Summary of the invention
For solving the problems referred to above, the invention provides a kind of rotor same polarity bonding magnetic steel positioner.By this device
Magnet steel applies pressure, overcomes magnet steel repulsive force each other, make magnet steel fit tightly with axle, can realize quickly positioning dress
Join.
The present invention is achieved by following technical solution.
A kind of rotor same polarity bonding magnetic steel positioner, including positioning sleeve and is evenly arranged along positioning sleeve circumferencial direction
Some elastic partss, described elastic parts is made up of screw, fastening block and spring, and described fastening block is positioned at inside positioning sleeve, and
Being connected with screw end, described spring housing is contained on screw, and between fastening block and positioning sleeve, described positioning sleeve center is also
It is provided with positioning boss.
Described screw is made up of screw rod and head of screw, and screw rod is connected by four directions boss with head of screw.
Be provided with the screw insertion hole for installing screw on described positioning sleeve, and screw insertion hole be provided above with
The cubic groove that four directions boss matches.

Described screw rod end uses with fastening block threadeds.
It is symmetrically connected with two pieces screw on described fastening block, and the spring model of suit is identical on two pieces screw.
The invention has the beneficial effects as follows:
Compared with prior art, the present invention solves the same polarity bonding magnetic steel problem of high power generation machine rotor, magnet steel
It is bonded on axle periphery, is located through and axial section, Internal hole positioning, magnet steel applies elastic pressure and is bonded in axle
On, and elastic parts is mobile, can be switched fast, improve working (machining) efficiency under force and release two states.The present invention can
Magnet steel with bonding adjacent repulsion quick, reliable, it will be apparent that improve assembling speed and assembly precision.This apparatus structure letter
Single, easily fabricated, swift to operate, can be in rotor magnetic steel adhesive technology field wide popularization and application.
