Problems solved by technology

Since the pipeline system needs to be changed frequently during the development stage of the aero-engine, the pipe shape is also constantly adjusted, which requires frequent design and manufacture of welding tooling, which not only brings a lot of waste of tooling, but also increases the development cycle of the pipeline system

Abstract

The invention belongs to the technical field of material engineering, and relates to a locating device for welding a guide pipe connector at any angle. The locating device comprises a base and a movable supporting arm, and an angle disc is fixed to a shaft. The part, below the angle disc, of the shaft is sleeved with a rotating block, and a rotating supporting arm is fixed to the rotating block. An angle indication block is fixed to the rotating block and provided with a first locking screw. A connector mounting block is fixed to the top of the angle disc. A connector mounting groove is formed in the top of the connector mounting block. A connector locating pin is arranged on one side of the connector mounting block, and a limiting plate is arranged on the other side of the connector mounting block. A locking screw of the guide pipe connector is arranged on the connector mounting block. The rotating supporting arm is sleeved with a sliding block, and an axial clamping block is arranged on the sliding block. The movable supporting arm is provided with a first guide groove, the axial clamping block is provided with a second guide groove, and the movable supporting arm and the axial clamping block are connected through pins arranged in the first guide groove and the second guide groove. An angular clamping block is hinged to the upper end of the movable supporting arm.

Description

technical field [0001] The invention belongs to the technical field of material engineering, and in particular relates to a positioning device for welding a conduit joint at any angle. Background technique [0002] There are more than 200 aero-engine pipelines, and the welding joints of a large number of pipes adopt 90° joints and three-way joints, generally using high-frequency induction brazing and argon arc welding, such as figure 1 , figure 2 shown. Due to the relative angle relationship between the conduit joint and the pipe, a special welding positioning tool must be designed for each conduit during the development stage to ensure the dimensional accuracy of the conduit. Since the pipeline system needs to be changed frequently during the development stage of the aero-engine, the pipe shape is also constantly adjusted, which requires frequent design and manufacture of welding tooling, which not only brings a lot of tooling waste, but also increases the development cy...
