Description
Technical field
Adjusted the present invention relates to the resonant frequency regulation technology field of electron vacuum device, more particularly to a kind of multi link plane
Humorous component and its assembling jig and method.
Background technology
Resonator is one of most important part in klystron, and its frequency characteristic is related to the power output of klystron
With the working characteristics such as bandwidth of operation.Resonator is typically processed using oxygenless copper material and obtained, in klystron development process, resonance
After chamber is through overpickling and multiple high temp welding sequence, the possible offset design value of final resonator frequency, so as to cause power water
The characteristics such as gentle bandwidth of operation can not meet design requirement.In order to reduce the side-play amount of resonator frequency and design load, Ke Yi
Regulating nail is installed on resonator, the frequency characteristic for changing resonator is changed by the insertion depth of regulating nail, afterwards by regulating nail
Sealing welding is on resonator.Though this regulative mode can reduce the side-play amount of resonator frequency, can not be carried out again after sealing
Regulation, is not suitable for high-frequency klystron.
Mechanical tuning technology is flake structure on one or more sidewall welds by resonator, is changed by the deformation of thin slice
Become the shape facility of resonator, and then change its frequency characteristic.Mechanical tuning technology can effectively adjust humorous within the specific limits
Chamber frequency shake to designated value, and then klystron is obtained the output characteristics for meeting and requiring.In klystron, especially in high-frequency speed
Adjust in pipe, adjusted to designated value resonator frequency by tunable technology, it is ensured that the working characteristics of klystron, is klystron development
In a key technology.
The tuning of klystron is divided into capacitance tuning and inductance tuning, inductance therein tuning be by adjusting resonance cavity wall,
Change resonator distributed inductance, and then reach the purpose for changing resonator frequency.The resonance cavity wall for being adjusted typically uses diaphragm
Structure, it does not only have adjustment effect, moreover it is possible to realize the vacuum sealing of resonator, and material property requirement is higher.
Conventional at present mechanical tuning frame mode as shown in figure 1, i.e. in a side opening of resonator 11, in each resonance
The open side of chamber 11 welds independent mechanical tuning device.Mechanical tuning device is main by diaphragm 21, regulation connecting rod 22 and external governor motion group
Into；The material of diaphragm therein 21 is generally stainless steel copper facing or ambrose alloy composite etc., diaphragm 21 it is generally rectangular in shape
Flake structure, the surrounding of its surrounding sealing welding to the open side of resonator 11, diaphragm 21 constitutes a side wall of resonator 11；Its
In regulation connecting rod 22 be welded on the outside normal direction center of diaphragm 21, the contact surface between regulation connecting rod 22 and diaphragm 21 is less than
The opening of resonator 11.When regulation connecting rod 22 is inwardly and outwardly pulled, the diaphragm between the regulation resonant cavity 11 of connecting rod 22
21 deform upon, and then change the frequency characteristic of resonator 11.In order to increase adjustable range, connecting rod 22 and resonance will be generally adjusted
Diaphragm 21 between chamber 11 is processed into crimp shape.There is following technological deficiency in conventional mechanical tuning structure：
(1) tuning block on each resonator is individually welded, complex structure, and volume is big, is unfavorable for the miniaturization of device；
(2) in the multiple mechanical tuning devices of welding, if one of diaphragm fails in welding, the high band is failure；
(3) for being operated in the klystron of high band, the size of space between its resonator is limited, and two adjacent diaphragms are same
When sealing welding difficulty it is big；
(4) multiple mechanical tuning devices be soldered to simultaneously when on klystron, it is necessary to erection welding mould structure form it is complicated.
For low frequency klystron, the resonator small volume in high-frequency klystron, the placement of mechanical tuning device is empty
Between it is very limited, mechanical tuning device difficulty is respectively welded on each resonator very big.
