Fixed type stitch welding device used for full hydraulic drive and numerical control friction stitch welding machine

Abstract

The invention discloses a fixed type stitch welding device used for a full hydraulic drive and numerical control friction stitch welding machine. The fixed type stitch welding device used for the full hydraulic drive and numerical control friction stitch welding machine comprises a stitch welding supporting frame, a main shaft installing frame and a main shaft. The stitch welding supporting frame comprises two left-right symmetric side plates; the two side plates are fixedly connected by two crossbeams which are arranged symmetrically front and back; the two crossbeams and the two side plates form a framework structure. The main shaft installing frame is connected in the stitch welding supporting frame in a sliding way. The main shaft is installed in the main shaft installing frame; the main shaft comprises a main shaft double-acting hydraulic cylinder and a stitch welding shaft, wherein the main shaft double-acting hydraulic cylinder comprises a cylinder barrel which is fixed in the main shaft installing frame; a barrel-shaped piston is arranged in the cylinder barrel of the main shaft double-acting hydraulic cylinder and the stitch welding shaft is supported in the piston; the upper end of the stitch welding shaft is connected with a hydraumatic motor by a coupling and the lower end of the stitch welding shaft is fixedly connected with a stopper; the hydraumatic motor is fixed at the upper end of the piston. The device is large in main shaft travel and operation space.

Description

technical field [0001] The invention relates to a fully hydraulically driven numerically controlled friction stitch welding machine, in particular to a fixed stitch welding device for a fully hydraulically driven numerically controlled friction stitch welding machine. 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 stitch welding mechanism. The supporting stitch-welding mechanism set on the arc-shaped frame moves along the axial direction and the circumferential direction of the arc-shaped frame respectively. Side cla...
