Description
Technical field
The present invention relates to Microwave transmission technology fields, and in particular to a kind of positioning side of combined type Millimeter Wave Rectangular Wave-guide
Method.
Background technique
Metal rectangular waveguide is the important component of microwave transmission, and the size that cavity is transmitted in standard waveguide will be using country's mark
Standard, but need to integrate all kinds of circuits inside most of waveguide assemblies, for convenience of cavity processing, Circuit assembly, it usually needs use
Combined type rectangular waveguide.When using combined type rectangular waveguide in the prior art, two pin positioning methods are generally used, such as Fig. 1 institute
Show, process two pin holes respectively in upper and lower two cavity parts corresponding position, pin and a cavity pin hole are interference fitted, and another
One cavity pin hole clearance fit；It is positioned by pin, so that transmitting cavity alignment in upper and lower two cavity part.Due to pin
Hole is processed respectively in each part, i.e., two pin holes is processed in a cavity part, the corresponding position in another cavity part
Two pin holes are processed, such processing cost height, inspection, assembly cost are higher, and pass through the ruler of control pin and transmission cavity
Very little to guarantee to position indirectly, positioning accuracy error is larger.
In conclusion existing combined type waveguide localization method has, processing cost is high, positioning accuracy error is big and examine,
The high defect of assembly cost.
Summary of the invention
The purpose of the invention is to overcome drawbacks described above existing in the prior art, a kind of registration, cost are provided
The localization method of low combined type rectangular waveguide.
To solve the above problems, the present invention proposes a kind of localization method of combined type rectangular waveguide, comprising the following steps:
Step 1: being inserted into positioning respectively at the lower microwave transmission chamber port in the lower metal cavity of combined type rectangular waveguide
Upper metal cavity is installed in lower metal cavity by block, and locating piece is made to be inserted into the upper microwave transmission chamber in upper metal cavity, will be upper
Microwave transmission chamber and lower microwave transmission chamber are cooperatively connected by locating piece, complete initial alignment；
It is screwed metal cavity and lower metal cavity Step 2: adopting after the completion of initial alignment, forms combined type square
Two locating pieces are then removed in shape waveguide；
Step 3: processing pin hole in combined type rectangular waveguide, and it is packed into pin, realizes repeatability positioning.
Further, above-mentioned pin is cylindrical stage stage structure, including the first rank of pin and is extended outwardly from the first rank of pin
Pin second-order, the diameter of the pin second-order is less than the first rank of pin；On first rank of pin and upper metal cavity
Pin hole interference fit, pin second-order and pin hole clearance fit in lower metal cavity.
Further, above-mentioned locating piece includes the fixture block that handle and handle top extend, the fixture block and handle joint face
For the step surface for limiting microwave transmission direction freedom degree, the fixture block two sides are limitation vertical microwave transmission direction freedom degree
Fixture block side, the size of the microwave transmission chamber port in the fixture block and combined type rectangular waveguide is adapted.
Further, the quantity of above-mentioned locating piece is two or more.
The characteristics of present invention combination microwave transmission cavity has to comply with standard size, combined type square is realized using locating piece
The initial alignment of the upper and lower metal cavity part of shape waveguide, locating piece and microwave transmission cavity size are adapted；Simultaneously initially fixed
Pin hole is processed in integration on the component of combined type rectangular waveguide behind position, is subsequently filled into pin, in subsequent assembly or is debugged
Cheng Zhong, no locating piece can also realize upper and lower metal cavity positioning, realize repeatability positioning, while locating piece can be in standard
It is reused in the combined type rectangular waveguide positioning operation of size, has saved cost.Locating piece includes handle and handle in the present invention
The fixture block that hand extends limits microwave transmission direction freedom degree by handle and the step surface of fixture block junction, by card
Fixture block side is arranged to limit vertical microwave transmission direction freedom degree in block two sides, while debugging for convenience, in maintenance process
It ressembles and positions, pin hole is directly processed on the integral component of combined type rectangular waveguide, not only reduces and is processed into
This, and machining accuracy is higher；Pin is cylindrical stage stage structure, including the first rank of pin and is extended outwardly from the first rank of pin
Pin second-order, the diameter of pin second-order is less than the first rank of pin, pin hole mistake on the first rank of pin and upper metal cavity
It is full of cooperation, pin hole clearance fit on pin second-order and lower metal cavity is convenient for assembly or disassembly.
In conclusion not only positioning accuracy is high for the method for the present invention, and it is easy to operate, processing cost is also reduced, is realizing weight
While positioning again, repetitive positioning accuracy is also improved.
