Further, the two halves of small-bore corrugated horn connects by alignment pin.
Further, small-bore corrugated horn is weldingly fixed in the cylindrical cavity of heavy caliber corrugated horn.
Further, the outer cylinder of the inner chamber of heavy caliber corrugated horn and small-bore corrugated horn and inner chamber concentricity≤0.02.
Small-bore corrugated horn two half-unit is grouped into, and can solve whole corrugated horn processing infeasibility, and these two minute half ripple loudspeaker are to process under the same mounting condition, so can guarantee the consistency of two parts and very high precision.After half ripple loudspeaker were installed by alignment pin in two minutes, reprocessing cooperated cylinder, has guaranteed the high concentricity with the heavy caliber corrugated horn.Alignment pin and dowel hole are arranged, again fine finishining after small-bore corrugated horn is installed on the small-bore corrugated horn.
Small-bore corrugated horn and heavy caliber corrugated horn are installed and are welded with vacuum hydrogen stove, and adopt air-cooled technique, and then according to little, that heavy caliber corrugated horn endoporus is processed whole corrugated horn installation location cylinder and pin-and-hole.
After whole corrugated horn assembles successfully, corrugated horn is carried out gold-plated electroplating technology process.
In order to guarantee to reach high-precision requirement, two minutes half small-bore corrugated horn clamped one times, disposable machining, thereby guarantee the consistency of two minutes half small-bore corrugated horns, then survey the way of limit location and installation by frontier inspection, make two and half ripple horn assembleds become the small-bore corrugated horn of a high concentricity, its concentricity is reached in 0.02, small-bore corrugated horn concentricity reach requirement and clamping reliable after, align reaming dowel hole again, and with the tight fit mode alignment pin is installed.
In order to guarantee that small-bore corrugated horn is with the concentricity of heavy caliber corrugated horn, after small-bore corrugated horn assembling and positioning is finished, the processing outer cylinder take small-bore corrugated horn inner chamber as benchmark, guarantee datum level with outer cylinder with the concentricity of inner chamber within 0.02.Simultaneously, the inner chamber of heavy caliber corrugated horn and the cylinder that cooperates with small-bore corrugated horn also are that disposable clamping processes, and guarantee that its concentricity is in 0.02.
It is that 82.6G is to the corrugated horn structure composition of 100G that a kind of novel millimeter wave corrugated horn of the utility model, this corrugated horn structure composition form are applicable to frequency range.
The version of heavy caliber corrugated horn and small-bore corrugated horn assembly welding and small-bore corrugated horn are combined by two parts, have guaranteed to realize guaranteeing simultaneously machining accuracy by the way of machining.Guaranteed the feasibility of processing technology, and rate of finished products is very high, almost can reaches 100% rate of finished products.This utility model is simple in structure, and is less demanding to cutter, and manufacturing cost is lower, and machining accuracy is high simultaneously, and plating property is good.
