Clamping device for thin-wall variable-section pipe

Abstract

The invention discloses a clamping device for a thin-wall variable-section pipe. The clamping device comprises a bottom plate, a first clamping module and a second clamping module, wherein the first clamping module is installed on the bottom plate and used for clamping a variable-section section thin-wall pipe, and the second clamping module is used for clamping a linear section thin-wall pipe; first sliding grooves used for allowing the first clamping module to be installed and second sliding grooves used for allowing the second clamping module to be installed are formed in the bottom plate;the first clamping module comprises V-shaped clamping mechanisms, vertical sliding rods and U-shaped mounting frames, wherein the vertical sliding rods are installed in the first sliding grooves, theU-shaped mounting frames are fixed on the vertical sliding rods, one ends of the V-shaped clamping mechanisms are connected to the vertical sliding rods, the middles of the V-shaped clamping mechanisms are connected to the U-shaped mounting frames, and V-shaped claws of the V-shaped clamping mechanisms are used for clamping the outer periphery of the variable-section section thin-wall pipe; and the second clamping module comprises a plurality of clamping sliding blocks, the clamping sliding blocks are installed in the second sliding grooves and are used for clamping the linear section thin-wall pipe. The clamping device has certain universality, and is accurate in positioning, and high in welding precision and operation efficiency.

Description

technical field [0001] The invention relates to the processing field of thin-wall variable-section pipes, in particular to a clamping device for thin-wall variable-section pipes. Background technique [0002] In the environmental control system, transportation system, and power system in the aerospace field, it is often necessary to use thin-walled variable-section tubes to make full use of the limited space to achieve the overall design and reduce the overall weight. When processing thin-walled variable-section tubes, the straight-line section thin-walled tubes and variable-section thin-walled tubes are generally pretreated by cutting, and then welded. During welding, the positioning requirements for the thin-walled pipes in the straight section and the thin-walled pipes with variable cross-section are very high. Due to the special scope of application of such pipe fittings, which belong to small batch production, if there is no targeted clamping device, the welding operat...
