Multi-point flexible clamping device for space special-shaped pipeline welding

Abstract

The invention discloses a multi-point flexible clamping device for spatial special-shaped pipeline welding. The multi-point flexible clamping device comprises a fixed bottom plate, a portal frame, a two-freedom-degree moving mechanism, a three-axis planar operation arm, a pipeline-joint composite clamp and five-freedom-degree position and gesture adjusting mechanisms arranged on the fixed bottom plate in a sliding mode; the two-freedom-degree moving mechanism is arranged at the horizontal part of the portal frame in a sliding mode; the three-axis planar operation arm is connected to the two-freedom-degree moving mechanism and is located under the two-freedom-degree moving mechanism; the portal frame stretches across the fixed bottom plate and is arranged on a cement foundation in a sliding mode; the five-freedom-degree position and gesture adjusting mechanisms are distributed on the fixed bottom plate at equal intervals in the direction of the portal frame; the pipeline-joint composite clamp is arranged above the five-freedom-degree position and gesture adjusting mechanisms. The multi-point flexible clamping device is reasonable in design, fast and accurate in operation and suitable for clamping and supporting large pipelines.

Description

technical field [0001] The invention relates to a technology in the field of mechanical processing, in particular to a multi-point flexible clamping device for welding space special-shaped pipelines. Background technique [0002] The space conduit system is a complex space system composed of several joints and special-shaped pipes. Its main function is to realize the communication relationship of the fluid system. It is often used to connect the gas and oil systems of automobiles, aircraft and even aerospace equipment. The manufacture of space conduit systems is usually achieved by welding, and the traditional manual positioning-welding method is still the most commonly used technical means in this field. This method has low production efficiency and poor positioning accuracy, and cannot meet the requirements of automated production for efficiency and precision. To solve this problem, it is necessary to design a flexible clamping tool suitable for complex space pipeline wel...

Problems solved by technology

[0004] Aiming at the problems that the prior art cannot flexibly clamp special-shaped pipeline joints, the number of clamping devices and the relative movement range are small, and it is difficult to solve the relative pose adjustment of each pipeline in the complex space pipeline system, the present invention proposes a space The multi-point flexible clamping device for special-shaped pipeline welding can quickly position the pipeline by sliding the five-degree-of-freedom position and posture adjustment mechanism set on the fixed base plate, and realize the large axial dimension through the pipeline-joint composite clamp. Flexible clamping of pipes and pipe joints, high operating flexibility
