Embodiment Construction

[0029] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings, but the claimed protection scope is not limited to the description.

[0030] Such as Figure 2-8 As shown, it is the tack welding and vacuum brazing fixture of the present invention, and the fixture is composed of a stepped annular fixture main body 1, a fan-shaped positioning block 2 for angular positioning, a positioning bolt 3, an annular pressing plate 4 and a pressing Composed of 5 bolts. Fixture positioning block 2 (such as Figure 6 ~ Figure 8 ) can control the angular position of the notch of the vortex device mounting seat 12, and its shape is fan-shaped, matching the notch shape (such as Figure 4 and figure 2 ), the fan-shaped axis points to the center of the fixture body 1, and at the same time, the fixture body 1 is provided with 12 bosses that match the shape of the bottom surface of the vortexer mounting seat 12 (such as figu...

Abstract

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.

Description

technical field [0001] The invention belongs to the field of welding technology, in particular to a brazing assembly fixture and an assembly method thereof. Background technique [0002] Flame tube head assembly components such as figure 1 As shown, it is composed of a ring 11 and 12 vortex mounts 12, which are completed by vacuum brazing. After welding, the flatness of the 12 planes of the vortex mount 12 is guaranteed to be less than 0.1mm and the angle of the notch is correct . [0003] At present, the processing method adopted is to reserve a machining allowance of 0.5 mm on the end face of the vortex generator mounting seat 12. After the parts are welded, milling is used to ensure the flatness of the parts to 0.1 mm. The specific processing route of the parts is as follows: Polishing—assembly tack welding—vacuum brazing—thermal calibration—milling. With this processing method, since the ring and the mounting seat are thin, the tool shakes during milling, which may ea...
