Background technology
The travelling-wave tubes negative electrode has single notes negative electrode, annotates negative electrode etc. more.Compare with single negative electrode of annotating, annotate the topmost characteristics of negative electrode more and be negative electrode by a plurality of independently little surface of emissions, the concentricity of the distribution of each surface of emission and negative electrode and heat shielding is very big to the influence of homogeneous tube electrical quantity.For this reason negative electrodes of annotating need the frock of precision more at fit on more, to satisfy the harsh requirement of multi-traveling wave tube to many notes negative electrode.There is the problem of complex structure, operating difficulties, uniformity and poor stability in traditional many notes negative electrode assembly tooling, and annotates negative electrode more and improve requirement day by day along with millimeter wave, and its machining accuracy of many notes negative electrode assembly tooling of original technology is more and more undesirable.
The utility model content
The purpose of this utility model provides a kind of travelling-wave tubes and annotates the negative electrode assembly tooling more, to solve many notes negative electrode assembly tooling complex structure, operating difficulties, uniformity and poor stability, the undesirable problem of precision of prior art.
In order to achieve the above object, the technical scheme that the utility model adopted is:
A kind of travelling-wave tubes is annotated the negative electrode assembly tooling more, include pedestal, described pedestal is provided with two relative boss, constitute the pedestal of U-shaped, it is characterized in that: the installing hole that has the common axially bored line that varies in size in two boss of described pedestal, be separately installed with the lining of coaxial line in two installing holes, wherein bigger installing hole apertura lateralis face place, aperture is equipped with plate, also include two guide rails, described guide rail rear portion is connected with the installation shaft with the corresponding coupling of lining in the installing hole respectively, the installation shaft at two guide rail rear portions is slidingly mounted on respectively in the corresponding installation holes for matching, two guide rails are installed in the inboard aperture face place of corresponding installing hole by the installation shaft at rear portion, described two guide rail positions are relative and parallel to each other, the guide rail that wherein is installed in the less installing hole in aperture has deep trouth from the flange of rail in guide rail, there is bolt to be screwed into installation shaft axle head the less installing hole in aperture from the outside of the less installing hole in aperture, has another bolt to pass described plate and be screwed into installation shaft axle head in the bigger installing hole in aperture.
Described a kind of travelling-wave tubes is annotated the negative electrode assembly tooling more, it is characterized in that: described lining two ends form interior chamfering respectively.
Described a kind of travelling-wave tubes is annotated the negative electrode assembly tooling more, it is characterized in that: the boss surface on pedestal and the pedestal, plate surface, two bolt surfaces are coated with nickel dam respectively.
Described a kind of travelling-wave tubes is annotated the negative electrode assembly tooling more, it is characterized in that: the guide rail installation shaft junction corresponding with it that is installed in less installing hole place, aperture forms step, described guide rail is installed in the installing hole place by installation shaft, and step is replaced at described installing hole inboard aperture face place.
Described a kind of travelling-wave tubes is annotated the negative electrode assembly tooling more, it is characterized in that: the guide rail installation shaft junction corresponding with it that is installed in bigger installing hole place, aperture is shaped to conical neck.
Described a kind of travelling-wave tubes is annotated the negative electrode assembly tooling more, it is characterized in that: described installing hole aperture is shaped to interior chamfering respectively.
In the utility model, in order to make the frock flexible operation, pedestal and boss are processed into " U " shape pedestal, boss has the installing hole of the common axially bored line that varies in size, and plate 4 is installed in the bigger installing hole outside, aperture.For the concentricity that makes pedestal 1 both sides improves a lot, we will put into two linings that are complementary with it 2 and lining 3 in the right and left hole.In order to make the lining correspondence put into the installing hole of boss, the installing hole aperture of boss is shaped to interior chamfering.In order to guarantee assembly precision, with the processing of quenching of two linings.In order to prevent the frock surface oxidation, we are at pedestal and boss, plate, bolt surface nickel coating, and nickel layer thickness is about 9 microns.In order to make negative electrode when pedestal takes out, avoid being subjected to unnecessary damages, chamfering is arranged in the pedestal external process.For the installation shaft that makes the guide rail in the less installing hole in aperture is stabilized in the corresponding lining, on described guide rail, be processed with step.In order to make the cathode heater legs of annotating in assembling, avoid coming to harm, process a deep trouth on the guide rail in the less installing hole in aperture more.For the guide rail in the bigger installing hole in aperture is slided flexibly, the conical neck with certain inclination angle is processed in the installation shaft junction that described guide rail is connected with it in corresponding lining.
The utility model compared with prior art, avoided machining to cause that the assembly tooling concentricity is not high, reduce negative electrode because of assembly tooling causes the misalignment of cathode base and heat shielding, guaranteed the stability of negative electrode assembling back concentricity, improved the qualification rate of cathode assembly.Finish assembling because of negative electrode on the higher frock of concentricity, the positioning accuracy of having avoided other negative electrode frock assembling mode to cause is not high, causes the cathode assembly concentricity inconsistent, very easily occurs intercepting and capturing electric current on anode.Because be on same frock, to finish assembling, so the concentricity of each cathode assembly all is very high, process repeatability and good stability.
