Wire lead slot 16 in a vertical axis square coil has certain flexibility, can moderately break into two with one's hands and be installed from the side annular coil framework
In intermediate card slot, it may be designed as general part, three axial coils of different arrays be suitble to use.
The principle of the present invention:
Silicon nitride ceramics axial annular coil rack has many advantages, such as that intensity is big, temperature expansion coefficient is small, in high temperature and pressure
Under environment, the stability of coil can be ensured；PEEK hangs down axis square coil skeleton with processability is strong, toughness is big, at low cost, high
The advantages that warm nature can be stronger, cooperation silicon nitride ceramics axial annular coil rack use, and coil rack difficult processing can be effectively reduced
Degree, cost, and the difficulty and risk of coil production are reduced, promote the symmetry, repeatability and consistency of coil.In addition,
The vertical axis square coil skeleton and vertical axial coil separated time retainer ring of PEEK material may be designed to three axial coil general parts, be effectively reduced whole
Cover coil array design and processing cost.
5 structure of axial annular coil rack of the present invention is simple, is easy to use silicon nitride ceramics processing, and silicon nitride material has
The advantages that hardness is big, the coefficient of expansion is small, acidproof, high temperature high voltage resistant, load portion of the axial annular coil rack 5 as three axial coils
Point, it can effectively promote the stability of instrument.
The present invention is hung down, and structure is complicated with vertical axial coil separated time retainer ring 3 for axis square coil skeleton 1, if using silicon nitride ceramics
Processing, yield rate is low, and processing cost is expensive.In addition, if vertical axis square coil skeleton 1 and vertical axial coil separated time retainer ring 3 make
It is processed with silicon nitride ceramics, after outer ring cutting, the cost for carrying out chamfering to trough rim is very high, and without chamfering, trough rim is quite sharp, institute
There is the coiling of directly contact trough rim, all gently can then be injured coat of paint by different degrees of incised wound, it is heavy then injure copper wire, it all can be right
The stability of three axis causes either large or small influence, this is that production three axial coil of high-performance institute is unacceptable.If used
High-temperature behavior is preferably and the PEEK material with fine processing performance is processed, and all disadvantages of silicon nitride material processing will be changed
Solution, can not only effectively improve machining yield, moreover it is possible to be fabricated to general part, three axis suitable for different the number of turns different lengths
Circle significantly reduces design cost and shortens the process-cycle.
The present invention is composed using the coil rack of two kinds of unlike materials, moreover it is possible to largely reduce by three axis loop knots
The risk that structure is divulged a secret.In general, silicon nitride ceramics coil rack is all made of external processing, after monomer coil external processing, will let out
Reveal all structural informations, as the core component of instrument, this is keenly-felt pain.And two kinds of unlike materials is used to carry out coil combination
After design, silicon nitride ceramics coil rack and PEEK material coil rack can entrust different manufacturers to process, to the entirety knot of coil
Structure plays good secrecy effect.
The above content is merely illustrative of the invention's technical idea, and this does not limit the scope of protection of the present invention, all to press
According to technical idea proposed by the present invention, any changes made on the basis of the technical scheme each falls within claims of the present invention
Protection scope within.
