Support device for welding fuel manifold

Abstract

A support device for welding a fuel oil header pipe comprises a base, a supporting rod, a support pipe, a rotating shaft, a guide rail rotating frame, a baffle and a positioning screw, one end of the supporting rod is fixedly connected to the base, and the other end of the supporting rod is fixedly connected to the side wall of the support pipe; one end of the rotating shaft is inserted into the support pipe; the center of the guide rail rotating frame is fixedly connected with the other end of the rotating shaft; the baffles are installed at the tail ends of the guide rail rotating frames respectively, and the positioning screws penetrate through the baffles and the guide rail rotating frames to connect the baffles and the guide rail rotating frames into a whole. The fuel manifold to be welded is clamped in a circle formed by the multiple baffles. Through the implementation of the device, a worker does not need to adjust the optimal welding position through a rotating part in the welding process, meanwhile, the position of the baffle connected to the guide rail rotating frame can be adjusted through the through groove formed in the guide rail rotating frame so that the device can adapt to header pipe structures of various sizes, and the device is convenient to disassemble, assemble and store, simple and easy to operate, convenient to operate by the worker and high in practicability. And the working efficiency and the welding quality are improved.

Description

technical field [0001] The invention belongs to the welding processing technology of an aero-engine fuel main pipe, and in particular relates to a support device for welding a fuel main pipe. Background technique [0002] The fuel main pipe used in a certain type of aero-engine is mainly composed of spray rod, lug seat, convex seat, oil inlet pipe assembly and semi-circular pipe. During processing, there are as many as 152 welds involved, and the number of welds is large. The diameter is large, and the outer diameter of the fuel pipe ring is generally about 500-1000mm. The workers and the workbench are fixed during welding, and the welding principle of the ring parts is mostly symmetrical welding. Therefore, when the ring is welded, the parts need to be rotated to adjust the symmetrical welding position. Or the best operating welding position, which makes the operation extremely inconvenient.

[0002] The fuel main pipe used in a certain type of aero-engine is mainly composed of spray rod, lug seat, convex seat, oil inlet pipe assembly and semi-circular pipe. During processing, there are as many as 152 welds involved, and the number of welds is large. The diameter is large, and the outer diameter of the fuel pipe ring is generally about 500-1000mm. The workers and the workbench are fixed during welding, and the welding principle of the ring parts is mostly symmetrical welding. Therefore, when the ring is welded, the parts need to be rotated to adjust the symmetrical welding position. or the best operating welding position, which makes the operation extremely inconvenient

In the original welding method, the worker sits at the station, and the number of suitable welding is 2-3. After the welding is completed, the parts need to be rotated so that the remaining unwelded welding is in the best operating position, and the cycle is repeated until all the welds are completed. Welding, reciprocating adjustment of the best position in this method is time-consuming, and the parts rotate on the workbench, which will inevitably cause friction and collision, which will affect the processing quality. Therefore, it is urgent to provide a special bracket for the welding of this part. To improve production efficiency and processing quality
