Reconfigurable tool for pipeline integral welding

Abstract

The invention discloses a reconfigurable tool for pipeline integral welding. The tool comprises a working platform, positioners, a clamp holder and the like. A certain number of positioners are arranged on the designated positions on the working platform of the tool; the positioners and the working platform are fixed through magnetic absorption; and the setting of spatial six-degree-of-freedom parameters of a pipe joint is finished by adjusting the positioners, and the clamping of the pipe joint is finished by use of the pipe joint clamp holder mounted on an actuator at the tail end of the positioners, so as to finish the ruling work before the pipeline welding and realize the pipeline integral welding. Through the invention, multiple pipe joints of different types can be clamped at the same time, and the interference is effectively avoided when multiple pipe joints are clamped at the same time. The adjustment of the positioners is realized by adjusting an external motor; and the entire configuration process does not need the assist of a high-accuracy measuring instrument, so that the tool can be quickly reconfigured, and the production efficiency of pipeline components is further improved.

Description

technical field [0001] The invention belongs to the field of fixtures. Specifically, multiple pipe joints of pipeline components are simultaneously positioned and clamped to complete the marking work of pipeline parts before welding, so as to carry out subsequent integral welding of pipeline components. Background technique [0002] At present, the positioning and clamping of pipe joints in the manufacture of spacecraft pipelines are all manually operated, using combined fixtures to clamp the pipe joints, and at the same time using high-precision measuring instruments such as laser trackers for auxiliary measurement, and then according to the measured position information Adjust the combination fixture to make the pipe joint reach the target position, and carry out the marking work of the pipeline components before welding. This method has the following deficiencies: 1) Since the entire configuration and adjustment process is done manually, the operation and adjustment are c...
