Vacuum brazing fixture and method for flame tube head assembly

The invention discloses a vacuum brazing fixture and method for a flame cylinder head assembly. The the clamp comprises a clamp body (1), a positioning block (2), a positioning bolt (3), a pressure plate (4) and a compression bolt ( 5). After using the clamp clamping ring (11) and the swirler mount (12), the polishing, assembling parts, positioning weld, and vacuum brazing are operated in turn tobraze. By means of the fixture and the method, the flatness of the part of 0.1 mm can be ensured, the milling process of the parts can be omitted, the positioning welding tool of the parts can be saved, the labor intensity of the workers can be reduced, the machining cost of the parts can be reduced, and the production efficiency of the parts can be improved. 本发明公开了种火焰筒头部组件的真空钎焊夹具及方法，其中夹具包括包括夹具主体(1)、定位块(2)、定位螺栓(3)、压板(4)和压紧螺栓(5)，使用本夹具装夹环(11)与涡流器安装座(12)后，按照抛光-装配零件-定位焊-真空钎焊的顺序进行钎焊。本发明保证了零件的平面度0.1mm的同时省去零件的铣加工工序，节省了零件的定位焊接工装，降低了工人的劳动强度，降低了零件的加工成本，提高了零件的生产效率。
