Abstract
The invention discloses methods for vacuum brazing, assembling and locating a radio fuse antenna radiator, which comprise the following steps that (1) a locating pin is utilized to preliminarily locate; and (2) at the welding line of a cover plate and a cavity body, burrs are generated through the nailing of a burr positioning tool, so precision locating is carried out. The method for locating is utilized, a soldering flake can be well enabled not to dislocate during the assembling process, the seam in the cover plate is enabled not to deviate, and the molten soldering flux is enabled to uniformly and fully filled, and does not flow into the cavity. The cavity and the cover plate can be tightly, uniformly and smoothly fit with each other, accordingly, the welding strength, air tightness and surface appearance quality are well ensured, the electrical property is enabled to be qualified, and finally, the welding quality can be enabled to satisfy the requirements of technical conditions. The methods for assembling and locating are utilized, the consumption of manpower and material resources is reduced, and the average assembling time for each set is 33 minutes, so the assembling efficiency is improved.
Description
Technical field
The present invention relates to a kind of localization method, especially a kind of electronic fuse antenna radiator vacuum brazing assembling and positioning method belongs to field of machining.
Background technology
Radiator is the significant components of electronic fuse antenna; Connect to form the microwave transmission passage through it and cable; Main effect is to accept, transmit, transmit, so the welding quality of radiator directly influences electrical property and electrical quantity, the accuracy of decision signal transmission.
The originally assembling of technology, welding localization method are: be contained in the welding step to weld tabs, the weld tabs size is consistent with the welding step, loads onto cover plate then, adopts spot welding that the weld seam of cover plate and cavity is positioned.Its shortcoming is: during (1) assembling, weld tabs very easily misplaces, and needs 2 people to cooperate; Often need repeatable operation,, occur folding line easily and fracture because weld tabs fragility is very big; Causing again again, the cutting weld tabs assembles; Cause the waste of manpower and materials, if weld tabs dislocation does not come to light, so fusing back scolder will inflow chamber in; (2) cover plate is loaded onto the back and is adopted the spot welding location in addition, and solder joint is bigger, influences apparent effect and surface roughness; (3) cavity and cover plate applying tight ness rating are inhomogeneous, influence uniformity and compactness that scolder is filled, cause weld strength low, the welding quality requirement that do not meet the specification; (4) if when assembling the cover plate size bigger than normal, then need polishing, if the degree varies appearance of cover plate both sides polishing will cause the crack on the cover plate to be departed from, with electrical property that directly influences the postwelding radiator and electrical quantity; (5) this method efficiency of assembling is low, and an average cover radiator installation time is 41 minutes.
Summary of the invention
For solving the problems of the technologies described above; The invention provides a kind of electronic fuse antenna radiator vacuum brazing assembling and positioning method, this method can guarantee that weld tabs does not misplace, and can guarantee that again cavity and cover plate fit fully; Smooth; Simultaneously can also guarantee suitable fit-up gap, so just can guarantee welding quality, satisfy the requirement of apparent mass and surface roughness simultaneously again.
The present invention is achieved through following technical scheme.
A kind of electronic fuse antenna radiator vacuum brazing assembling and positioning method, its step is following:
1. utilize alignment pin to carry out Primary Location;
2. in the commissure of cover plate and cavity, follow closely out burr, accurately locate with the burr positioning tool.
Said alignment pin is arranged at welding step two ends, and the position corresponding with locating piece is provided with the locating hole of cooperation on the cover plate.
Beneficial effect of the present invention is:
Can guarantee that weld tabs does not misplace; Can guarantee the requirement of apparent mass and surface roughness again, guarantee cavity and cover plate fit fully, smooth, the while can also guarantee suitable fit-up gap; Guarantee welding quality; And can guarantee that the crack on the cover plate do not depart from, guarantee the electrical property and the electrical quantity of postwelding radiator, and can be improved by efficiency of assembling.

The specific embodiment
Further describe technical scheme of the present invention below in conjunction with accompanying drawing, but require the scope of protection to be not limited to said.
A kind of electronic fuse antenna radiator vacuum brazing assembling and positioning method, its step is following:
1. utilize alignment pin 3 to carry out Primary Location;
2. at weld seam 7 places of cover plate 4, follow closely out burr, accurately locate with burr positioning tool 8 with cavity 1.
To shown in Figure 3, said alignment pin 3 is arranged at welding step 2 two ends like Fig. 1.
As shown in Figure 4, be provided with the locating hole 5 of cooperation on the cover plate 4 with alignment pin 3 corresponding positions.When cover plate 4 assemblings, be contained in bonding pad on the welding step 2 of cavity 1 earlier, alignment pin 3 is passed at the weld tabs two ends, on weld tabs, loads onto cover plate 4 then, guarantees that locating hole 5 is identical with the alignment pin 3 on the cavity 1.The effect of utilizing alignment pin 3 to carry out Primary Location is, can be good at guaranteeing that weld tabs does not misplace in the assembling process, only needs one man operation; Reduce the manpower and materials waste; Improve efficiency of assembling, and filling is even, full after guaranteeing solder fusing, does not flow in the chamber of cavity 1; Avoid Lou weldering, guarantee good air-tightness.Simultaneously through alignment pin 3 and locating hole 5, when having avoided assembling because cause departing from of crack 6 on the cover plate 4 during the polishing bigger than normal of cover plate 4 sizes, thereby it is qualified to guarantee that radiator postwelding electrical property well reaches electrical quantity.
Said at weld seam 7 places of cover plate 4 with cavity 1; Follow closely out burr with burr positioning tool 8; Accurately locate, can make cover plate 4 and cavity 1 produce the broken edge that shape matches, its contact-making surface is protruding to be meshed with concave portion is staggered; Thereby improve the applying tight ness rating of cover plate 4 and weld tabs and cavity 1, guarantee that radiator welding back air-tightness is good.In general, when following closely out burr, need evenly follow closely out a week with whole welding line 7 places of cavity 1 at cover plate 4 with burr positioning tool 8.
Burr positioning tool 8 as shown in Figure 5, material is generally selected 1Cr18Ni9Ti for use, after processing, preserves with oil sealing.Can guarantee that like this burr positioning tool has good non-oxidizability, corrosion resistance, and economy and durability.
Follow closely out burr carries out pinpoint effect and is at cover plate 4 and weld seam 7 places of cavity 1; Can fit tight, even, smooth with cover plate 4 machine weld tabs by fine assurance cavity 1; Can guarantee that again weld tabs fusing back filling is even, full; Thereby guarantee to satisfy the requirement of weld strength, air-tightness and apparent mass and surface roughness aspect well, guarantee that finally welding quality can satisfy specification requirement.
Utilizing the assembling and positioning method in this method, reduce manpower and materials and expend, is 33 minutes between average every suit timing, has improved efficiency of assembling.
