Abstract
The utility model provides a negative pole coating film frock which characterized in that: including base and chassis, the tubular structure of base for having the chassis mounting hole, the chassis is the shape of falling a boss structure, install on the chassis in the mounting hole of chassis, set up a plurality of through -holes that correspond with coating film negative pole size on the chassis. The utility model discloses can ensure the quality of negative pole coating film, again because have very big commonality, greatly reduced changes the cost of frock and processing frock, indirectly brings economic benefits for the enterprise.
Description
Technical field
The utility model relates to a kind of plated film frock, particularly a kind of plated film frock of negative electrode.
Background technology
HIGH-POWERED MICROWAVES device is the core devices of radar, electronic warfare, communication and guidance system in modern weapons equipment, and negative electrode is these core devices " hearts ", is also the key part affecting device lifetime.During design negative electrode; need to fully take into account because of have: resistance to ion bombardment, high pressure resistant, resistance to poisoning, vibration resistance, shock-resistant, anti-sparking, emissive power and life-span are grown; based on these requirements; usually can select overlay film immersion type barium-tungsten dispense cathode, cover one deck noble metal film on the surface of negative electrode, the work function of negative electrode can be reduced; improve the emissive power of negative electrode; under equal working current condition, reduce negative electrode working temperature, and extend negative electrode working life.Simultaneously before overlay film, adopt ion etching technology anticathode surface to process, make negative electrode expose fresh surface, substantially increase the compound film quality of negative electrode.Therefore, this type of negative electrode has the advantages such as larger emission, working stability, anti-poisoning capability be strong.During plated film, need, according to cathode size, negative electrode be installed in suitable plated film frock, usually, a kind of negative electrode will corresponding to a plated film frock, and in the plated film lithography of accumulative some cycles, frock has wearing and tearing, and causes size to depart from original size, so need periodic replacement, but existing plated film frock does not have versatility, tooling cost is too large, is unfavorable for Reducing Cost in Enterprises.
Summary of the invention
Do not have versatility to overcome existing plated film frock, tooling cost is too large, is unfavorable for the deficiency of Reducing Cost in Enterprises, the utility model provides a kind of plated film frock, there is very large versatility, greatly reduce the cost changing frock and processing tool, indirectly for enterprise brings economic benefit.
For achieving the above object, the present invention is realized by following technique means:
A kind of negative electrode plated film frock, it is characterized in that: comprise pedestal and chassis, described pedestal is the tubular construction with chassis open holes, and described chassis is the structure of falling boss shape, described chassis is arranged in the open holes of described chassis, chassis offers multiple through hole corresponding with plated film cathode size.
Further:
The internal diameter of described pedestal matches with the external diameter on described chassis, the chassis open holes diameter of described pedestal and matching of chassis boss external diameter.
The base thickness of described pedestal, the upper base thickness on chassis, chassis base thickness are 2 ± 0.5mm.
The material on described pedestal and chassis is high-temperature material molybdenum or tungsten.
The invention has the beneficial effects as follows: the quality that can ensure negative electrode plated film, again because have very large versatility, greatly reduce the cost changing frock and processing tool, indirectly for enterprise brings economic benefit.
Accompanying drawing explanation
Fig. 1 is the plated film tool structure schematic diagram in the utility model, and wherein, a is front view, and b is vertical view, and Fig. 2 is base construction schematic diagram, and Fig. 3 is chassis structure schematic diagram.
Embodiment
Below in conjunction with Figure of description, the present invention is further illustrated.
As shown in accompanying drawing 1--3, a kind of negative electrode plated film frock, it is characterized in that: comprise pedestal 1 and chassis 2, described pedestal 1 is the tubular construction with chassis open holes, described chassis 2 is the structure of falling boss shape, described chassis 2 is arranged in the open holes of described chassis, chassis 2 offers multiple through hole D3 corresponding with plated film cathode size, for installing by plated film negative electrode.
Chassis is mounted in the lower bottom part of pedestal, and pedestal periphery size is fixed based on concrete coating equipment equipment size.
Further:
The internal diameter D1 of described pedestal 1 matches with the outer diameter D 3 on described chassis 2, the chassis open holes diameter D2 of described pedestal 1 and matching of chassis boss outer diameter D 4.
The base thickness H1 of described pedestal, the upper base thickness H3 on chassis, chassis base thickness H2 are 2 ± 0.5mm.
The material on described pedestal 1 and chassis 2 is high-temperature material molybdenum or tungsten.But based on processing characteristics and cost, tend to select molybdenum.
More than show and describe ultimate principle of the present invention, principal character and advantage.The technician of the industry should understand; the design is not restricted to the described embodiments; the principle that the design is just described described in above-described embodiment and specification sheets; under the prerequisite not departing from the design's spirit and scope; the design also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the design.The claimed scope of the design is defined by appending claims and equivalent thereof.
