Abstract:
1. A high temperature brazing fixture for a component, the high temperature brazing fixture comprising: a first frame member made of a superalloy, the superalloy having a coefficient of thermal expansion sufficiently similar to that of the component so as to not cause the component or its parts to be moved out of tolerance during brazing operations; a second frame member made of the superalloy; a first support member made of the superalloy and configured to interface with and support at least a first portion of the component, the first support member mechanically coupled to the first frame member and to the second frame member; a first tab that extends from one of the first support member and the first frame member, and passes through a first corresponding slot in the other of the first support member and the first frame member; a first tab lock abutting at least a portion of the first tab, such that the first tab is locked in place and prevented from passing back through the first corresponding slot; a second tab that extends from one of the first support member and the second frame member and passes through a second corresponding slot in the other of the first support member and the second frame member; a second tab lock abutting at least a portion of the second tab, such that the second tab is locked in place and prevented from passing back through the second corresponding slot; a first positioning member made of the superalloy and configured to interface with and position at least a first location of or hold a first dimension of the component, the first positioning member mechanically coupled to the first frame member and to the second frame member; a third tab that extends from one of the first positioning member and the first frame member and passes through a third corresponding slot in the other of the first positioning member and the first frame member; a third tab lock abutting at least a portion of the third tab, such that the third tab is locked in place and prevented from passing back through the third corresponding slot; a fourth tab that extends from one of the first positioning member and the second frame member and passes through a fourth corresponding slot in the other of the first positioning member and the second frame member; a fourth tab lock abutting at least a portion of the fourth tab, such that the fourth tab is locked in place and prevented from passing back through the fourth corresponding slot; wherein at least one of the first tab, the second tab, the third tab, and the fourth tab is a T-type tab, the T-type tab having a first section and a terminal section, the terminal section being wider than the first section, and its corresponding slot allows the terminal section to pass through the slot while the first section extends through the slot; and wherein at least one of the first tab lock, the second tab lock, the third tab lock, and the fourth tab lock comprises two half locks, each half lock partially surrounds the first section of the T-type tab, and each half lock is located opposite the other between the terminal section and the slot.
