Abstract

The invention provides a fixing fixture and a machining method for fuel spray nozzles. The fixing fixture for the fuel spray nozzles comprises a supporting assembly (10), a positioning assembly (20) and a clamping assembly (30). The positioning assembly (20) is arranged on the supporting assembly (10) and is provided with a supporting hole (21) which is matched with a spray nozzle seat (1) of each fuel spray nozzle; the clamping assembly (30) is arranged on the supporting assembly (10) and comprises a first clamping part (31) and a second clamping part (32), and a shell (4) of each fuel spray nozzle can be clamped by the first clamping part (31) and the second clamping part (32) from two opposite directions. According to the technical scheme, the fixing fixture and the machining method have the advantage that the problem of high braze welding difficulty due to complicated structures of fuel spray nozzles in the prior art can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a fixing fixture for a fuel nozzle and a processing method for the fuel nozzle. Background technique [0002] At present, there are few fuel nozzles for engines that need to be brazed. The fuel nozzle of an engine includes a nozzle seat, a casing, and a vacuum brazing method to weld the nozzle seat, the casing, and the nozzle. The brazing seam that needs to be welded is only Two, only one height dimension needs to be controlled, and the tolerance is relatively large (with a tolerance of 0.3mm). The parts of the fuel nozzle have a simple structure and are less difficult to braze. [0003] The turboshaft aircraft engine fuel nozzle includes a nozzle seat 1 , a casing 2 , a fuel pipe 3 , a casing 4 , a nozzle 5 , a swirler 6 , a first pin 7 and a second pin 8 . Vacuum brazing is used to weld the nozzle seat 1, casing 2, fuel pipe 3, casing 4, nozzle 5, first pin 7 and...
