Background technique
Fan-shaped magnet is applied to ion thruster.Since the size of ion thruster upper magnetic pole is generally large, and permanent magnet
It is hard brittle material, it is broken that fracture easily occurs under shock loading, therefore the permanent magnet in magnetic pole is all divided into lesser magnetic patch
It is magnetized and is installed.But permanent magnet piecemeal brings very big difficulty to the installation of magnetic pole: having between permanent magnet very big
Repulsion, when magnetic patch number is more, during the installation process easily overturning fly out, not only result in permanent magnet and damaged because colliding with, more
It is that very big security risk is brought to installation personnel.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of ion thruster fan-shaped magnet mounting devices and installation side
Method is able to solve fan-shaped magnet problem difficult to install.
A kind of mounting device of fan-shaped magnet, including fan groove (2), cover board (3) and plug (4)；The fan groove (2) is
The circular groove that upper end and both ends are open, at the both ends of fan groove (2), bottom surface is respectively provided with one of through slot along radial direction；
The cover board (3) is curved plate-like structure, is fixedly mounted in fan groove (2) upper end opening, forms one with fan groove and is used for
The curved channel of fan-shaped magnet is installed；The plug (4) is a plate structure, altogether there are two, can be logical from the both ends of fan groove (2)
It is inserted at slot.
Preferably, the cover board (3) is connect by cutting with scissors ear structure with external device.
Preferably, the fan groove (2) and cover board (3) are fixed together by welding.
A kind of installation method of the mounting device of fan-shaped magnet, specifically: by a plug (4) from the one of fan groove (2)
It is inserted into, contradicts on cover board (3), by the closed at one end of curved channel at a through slot；From the other end of curved channel, it is sequentially loaded into
Permanent magnet (1), after the installation for completing all permanent magnets (1), by another plug (4) from another through slot of fan groove (2)
Place's insertion, the other end in closed arc channel.
The invention has the following beneficial effects:
Ion thruster of the invention fan-shaped magnet mounting device and installation method, are constituted using fan groove and cover board
One hollow arc-shaped channel, when installation, permanent magnet is sequentially placed into channel from arc-shaped channel end opening, removes one
Outside circumferential free degree, remaining five freedom degree of permanent magnet are limited, it is impossible to are flipped, to greatly reduce magnetic
Block flies out the probability hurted sb.'s feelings, and improves the safety of permanent magnet installation, reduces the installation difficulty of permanent magnet；And the device is just
The plug of side only need to be opened when needing to magnetize permanent magnet taking-up in dismounting, therefore permanent magnet is facilitated to take out and fill
The operation filled out.

Specific embodiment
The present invention will now be described in detail with reference to the accompanying drawings and examples.
The present invention provides a kind of mounting devices of fan-shaped magnet, the sector being spliced to form for installing multiple permanent magnets 1
Magnet, the permanent magnet 1 are arc-shaped magnet, and the corresponding central angle of permanent magnet 1 of each arc-shaped is α, total magnet numbers
For n, 360 ° of < of the total angle n α of fan-shaped magnet；
As illustrated in the accompanying drawings from 1 to 3, mounting device of the invention includes: fan groove 2, cover board 3 and plug 4；The fan groove 2 is
The circular groove that upper end and both ends are open, size and shape are consistent with the fan-shaped magnet that permanent magnet 1 is spliced to form, and can limit
Three rotary freedoms of permanent magnet 1 processed and a radial freedom degree；At the both ends of fan groove 2, bottom surface is respectively opened along radial direction
There is one of through slot.
The cover board 3 is arc-shaped plate structure, is fixedly mounted in 2 upper end opening of fan groove, forms one with fan groove 2
A arc-shaped channel, cover board 3 can limit an axial freedom of permanent magnet 1, and the both ends of cover board 3 and fan-shaped central region are equipped with
Ear structure is cut with scissors, is whole device and extraneous installation interface, if the angle of fan-shaped magnet is larger, can be increased in the position that cover board 3 is fitted
Add more hinge ears.
The plug 4 be a plate structure, altogether there are two, can be inserted into from the both ends through slot of fan groove 2, cooperation fan groove
2 can limit a circumferential free degree of permanent magnet.
In this example: the quantity of the permanent magnet 1 is 20, and each central angle alpha is 6 °；
The center radius of circle of the fan groove 2 is 175mm, and fan angle is 130 °, and the groove width of groove is 10mm, and two logical
Slot and axis angle are 61 °, through slot long 10mm, wide 1.5mm；
The center radius of circle of the cover board 3 is 175mm, altogether there are three ear is cut with scissors, is distributed in fan-shaped both ends and middle part, installation
Bore dia is 3.2mm；
The size of the plug 4 is 10mm × 8mm × 1.5mm.
Its connection relationship is as follows:
The alignment of the center of circle of fan groove 2 and cover board 3, axis alignment, top surface alignment are fixed as by welding or other modes
One forms a hollow curved channel, limits remaining five freedom degree of permanent magnet 1 in addition to circumferential free degree；Two
The fan-shaped magnet that above permanent magnet 1 forms is located in curved channel, and there are certain gaps between adjacent permanent magnet 1；When
In curved channel after the installation is completed, since there are gaps between permanent magnet 1, under the magnetic force, gap is uniform to permanent magnet 1
, therefore can guarantee that the Distribution of Magnetic Field of entire magnet ring is circumferentially being also uniform.
Plug 4 is inserted into from the through slot of fan groove 2, is contradicted onto cover board 3, the both ends of closed channel, limitation permanent magnet 1
Circumferential free degree；Cover board 3 cuts with scissors the mounting hole on ear by it and is mounted on ion thruster, realizes the peace of the fan-shaped magnet
Dress.
Mounting process process:
One plug 4 is inserted into from a through slot of fan groove 2, is contradicted onto cover board 3, by the one end in arc-shaped channel
Closing；The other end from arc-shaped channel is sequentially loaded into permanent magnet 1, after the installation for completing all magnetic patch, by another plug
4 are inserted into from another through slot of fan groove 2, the other end of closed circular curved channel.
In conclusion the above is merely preferred embodiments of the present invention, being not intended to limit the scope of the present invention.
All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in of the invention
Within protection scope.
