Clamping device of thin-walled tube

Abstract

The invention discloses a clamping device of a thin-walled tube. The clamping device of the thin-walled tube comprises a vertical sliding rod, a plurality of V-shaped clamping mechanisms installed onthe vertical sliding rod and supporting mechanisms. The vertical sliding rod is provided with a vertical sliding slot. Each V-shaped clamping mechanism comprises a pair of clamping arms with adjustable angles and a guide sliding frame, wherein the clamping arms are installed at one end of the guide sliding frame, the other end of the guide sliding frame is installed on the vertical sliding rod. Each guide sliding frame is provided with a vertical guide sliding groove, and the vertical sliding rod penetrates through the vertical guide sliding grooves. The V-shaped clamping mechanisms are installed on the vertical sliding rods through fixing devices. The supporting mechanisms are U-shaped installation frames or trapezoidal supporting frames. The supporting mechanisms support the lower portions of the V-shaped clamping mechanism. The clamping device has a certain universality, suitable for clamping thin-wall tubes of a certain tube dimension range, accurate in locating and high in weldingprecision and operation efficiency.

Description

technical field [0001] The invention relates to the processing field of thin-walled pipes, in particular to a clamping device for thin-walled pipes. Background technique [0002] In the environmental control system, transportation system, and power system in the aerospace field, thin-walled tubes are often required to make full use of the limited space to achieve the overall design and reduce the overall weight. When processing thin-walled tubes, each part of the thin-walled tubes is generally cut first, and then welded. During welding, the positioning requirements for each part of the thin-walled tube 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 operation can only be performed by manual positioning, which will easily lead to low processing accuracy, low operation efficiency, and time-consuming and laborious The problem.
