Description
Technical field
A kind of shaping jig, particularly a kind of hot-wire forming fixture.
Background technology
Along with the development of microwave technology, start to adopt Novel rod control techniques in microwave tube, compared with common microwave tube, bar control microwave tube has that the utilance of the target surface of emission is high, control voltage is low, electronics relatively little to electron beam disturbance converge be more prone to, can bear more high power capacity electron emission, there is the advantages such as better reliability.But, adopt the requirement of the microwave tube target of bar control techniques and heated filament very special, metal poles as control electrode needs to run through from the shaft core position of negative electrode, this just needs the passage that negative electrode will have control lever run through, not only need cathode emitter to be hollow-core construction, its heated filament also requires it is hollow-core construction.Usually, hollow heated filament is like this shaping and obtain on specific fixture by the helix of two semi-circular shapes, existing shaping jig is provided with cannelure on one piece of base plate, for placing two parts semicircular spin line, separately there is the cover plate that one piece of width is equal to base plate, cover plate is covered on base plate, afterwards operating personnel hand-held assembling after workpiece and fixture, carry out next step hot-wire forming.This shape-setting clamp existing is easily shifted in use, and product quality is low, inefficiency.
Utility model content
For solving the deficiencies in the prior art, the purpose of this utility model is to provide a kind of microwave tube fixture when hot-wire forming to stablize, and the product quality after shaping is high, and operating procedure is simple.
In order to realize above-mentioned target, the utility model adopts following technical scheme:
Microwave tube hot-wire forming fixture, comprise: the base plate being provided with the cannelure for placing two parts semicircular spin line, clamping is placed on the cover plate of base plate, be connected to the clip assembly between base plate and cover plate, clip assembly composition has: the clamping extending base plate corner location is protruding, protruding and be located at the clamping groove of cover plate corner location corresponding to clamping.
Aforesaid microwave tube hot-wire forming fixture, base plate also forms to be had: two holding tanks between being formed at apart near two clamping projections, connects the base plate body of two holding tanks.
Aforesaid microwave tube hot-wire forming fixture, cover plate also forms to be had: the Access Division between being formed at apart near two clamping grooves, connects the cover board body of two Access Divisions.
Aforesaid microwave tube hot-wire forming fixture, holding tank be wider than the wide of Access Division.
Aforesaid microwave tube hot-wire forming fixture, the 0.02 ~ 0.05mm being wider than Access Division of holding tank.
Aforesaid microwave tube hot-wire forming fixture, the length of base plate body is greater than the length of cover board body.
Aforesaid microwave tube hot-wire forming fixture, the length of base plate body is greater than 0.02 ~ 0.05mm of cover board body.
Usefulness of the present utility model is: the utility model provides a kind of microwave tube fixture when hot-wire forming to stablize, and the product quality after shaping is high, and operating procedure is simple.
Accompanying drawing explanation
Fig. 1 is the front view of a kind of embodiment of the utility model shaping jig;
Fig. 2 is the front view of a kind of embodiment of the utility model base plate;
Fig. 3 is the front view of a kind of embodiment of the utility model cover plate;
The implication of Reference numeral in figure:
1 base plate, 101 clampings are protruding, 102 holding tanks, 103 base plate bodies, 2 cover plates, 201 clamping grooves, 202 Access Divisions, 203 cover board bodies, W1 holding tank wide, W2 Access Division wide, the length of L1 base plate body, the length of L2 cover board body.
Embodiment
Below in conjunction with the drawings and specific embodiments, concrete introduction is done to the utility model.
Microwave tube hot-wire forming fixture, comprise: the base plate 1 being provided with the cannelure for placing two parts semicircular spin line, clamping is placed on the cover plate 2 of base plate 1, be connected to the clip assembly between base plate 1 and cover plate 2, clip assembly composition has: the clamping projection 101 extending base plate 1 corner location, is located at the clamping groove 201 of cover plate 2 corner location corresponding to clamping protruding 101.Only the clamping groove 201 of protruding for the clamping of cover plate 2 101 corresponding base plates 1 need be installed, base plate 1 and cover plate 2 can easily be located.
Base plate 1 also forms to be had: two holding tanks 102 between being formed at apart near two clamping projections 101, connects the base plate body 103 of two holding tanks 102.Cover plate 2 also forms to be had: the Access Division 202 between being formed at apart near two clamping grooves 201, connects the cover board body 203 of two Access Divisions 202.
The wide W1 of holding tank 102 is greater than the wide W2 of Access Division 202; Optimum gap is: the wide W1 of holding tank 102 is greater than the 20.02 ~ 0.05mm of the wide W of Access Division 202.The length L1 of base plate body 103 is greater than the length L2 of cover board body 203; Optimum gap is: the length of base plate body 103 is greater than 0.02 ~ 0.05mm of cover board body 203.; After heated filament being positioned over the cannelure on base plate 1, cover cover plate 2, located by the cooperation of W1 and W2, L1 and L2, after operating personnel's assembling, carry out next step hot-wire forming, any displacement can not be produced, installation and removal convenience all very, drastically increases operating efficiency.
The utility model provides a kind of microwave tube fixture when hot-wire forming to stablize, and the product quality after shaping is high, and operating procedure is simple.
