Abstract

The invention discloses a crossbeam fixing type all-hydraulic driving digital-control friction stitch welding machine with a large operating space. The crossbeam fixing type all-hydraulic driving digital-control friction stitch welding machine comprises a machine frame, a clamping mechanism, a circumferential moving mechanism and a welding device, wherein the clamping mechanism, the circumferential moving mechanism and the welding device are connected to the machine frame; the welding device comprises a welding bracket, a main shaft mounting frame and a main shaft; the welding bracket comprises a left side plate II and a right side plate II which are symmetrical; the two side plates II are fixedly connected together through a front crossbeam and a rear crossbeam; a framework structure is formed by the two crossbeams, the left side plate II, and the right side plate II; the main shaft mounting frame is in sliding connection to the welding bracket; the main shaft is mounted in the main shaft mounting frame, and comprises a main shaft dual-action hydraulic cylinder and a welding shaft; the main shaft dual-action hydraulic cylinder comprises a cylinder barrel fixed to the main shaft mounting frame; a barrel-shaped piston is arranged in the cylinder barrel of the main shaft dual-action hydraulic cylinder; the welding shaft is arranged in the piston in a supporting manner; the upper end of the welding shaft is connected with a hydraulic motor through a coupling; the hydraulic motor is fixed on the upper end of the piston; and a stopper rod is fixedly connected to the lower end of the welding shaft. The crossbeam fixing type all-hydraulic driving digital-control friction stitch welding machine disclosed by the invention is large in operating space and large in working range.

Description

technical field [0001] The invention relates to a fully hydraulically driven numerical control friction stitch welding machine, in particular to a fully hydraulically driven numerically controlled friction stitch welding machine with a large operating space and a fixed beam. Background technique [0002] Nowadays, seabed resources in the world are highly valued by all countries, and the exploitation and utilization of seabed resources are intensifying. The repair of equipment for the exploitation of seabed resources is also given corresponding attention. [0003] Patent document CN103071914A discloses a fully hydraulically driven reconfigurable numerical control friction stitch welding machine underwater operation device. The equipment mainly includes an arc-shaped frame and a welding mechanism. The supporting welding mechanism arranged on the arc-shaped frame moves along the axial direction and the circumferential direction of the arc-shaped frame respectively. The clampi...
