Abstract

The invention provides a local dry-type underwater friction stitch welding device. The device mainly consists of a sealing gasket (2), a cover body (3), a stopper adapter component (4), a hydraulic cylinder body (5), a transmission shaft (6), a support bearing (7), a hydraulic cylinder piston (8) and a hydraulic motor (9), wherein the stopper and a workpiece are in friction to produce heat in the friction stitch welding process, as heat convection is existeds in the environment with water, a large amount of the heat produced by the friction is lost; and the existing of water causes quenching for the workpiece, so as to greatly affect the welding process; . according According to the device provided by the invention, the novel cover body and the sealing gasket are arranged on a welding spindle head, the water is discharged through the high pressure gas during welding to form a local dry-type space, and then the welding is carried out. The device provided by the invention is simple in structure, convenient in use, reliable in performance, economical and practicable, and can be used for realizing underwater friction stitch welding.

Description

Local dry-type is the friction stitch welding device under water
Technical field
The present invention relates to field of welding devices, especially a kind of local dry-type is the friction stitch welding device under water.
Background technology
Countries in the world are just of a great variety at the underwater welding method of application and research at present, and what application was ripe is arc welding, and have underwater wet-type welding, underwater local dry welding and underwater dry-type commonly used weld.The underwater wet-type welding equipment is simple, with low cost, flexible operation, strong adaptability, but welding quality is unsatisfactory; The welding quality of underwater dry-type welding is more satisfactory, but needs pressure chamber or the operating room of Design and manufacture complexity, and equipment is complicated, cost is higher.In addition, the difficult deep water structure object REPAIR WELDING that realizes of above welding method, and friction stitch welding is as a kind of solid phase interconnection technique, it is less that welding quality is affected by the depth of water and environmental pressure, therefore can realize the REPAIR WELDING of deep water structure object, its correlation technique is significant for the development of Underwater Engineering.
Summary of the invention
According to background technology; the object of the present invention is to provide a kind of local dry-type friction stitch welding device under water; this drainage arrangement can effectively form reliable and stable local dry-type space, can carry out gas shield to welding process; thereby under the solution water environment in the welding process thermal loss reach more greatly material quenching phenomenon, improve welding quality.
To achieve these goals, the present invention adopts following technical scheme:
A kind of local dry-type is the friction stitch welding device under water, mainly formed by sealing gasket (2), cover body (3), stopper switching part (4), hydraulic cylinder body (5), power transmission shaft (6), spring bearing (7), hydraulic cylinder piston (8), hydraulic motor (9), wherein: cover body (3) connects hydraulic cylinder body (5), between workpiece and cover body (3), sealing gasket (2) is set, be bolted with hydraulic motor (9) at hydraulic cylinder body (5), realize the location by spring bearing (7) between power transmission shaft (6) and the hydraulic cylinder piston (8).
Described cover body (3) is installed on the friction stitch welding main tapping, builds local dry-type environment in the Underwater Welding process.
Described sealing gasket (2) adopts elastomeric material.
Owing to adopted technique scheme, the present invention to have following advantage and effect:
(1) the present invention has been installed drainage cover additional at the friction stitch welding main tapping, has realized the construction of local dry-type environment in the Underwater Welding process, has reduced the impact of water environment on welding process as far as possible;
(2) the present invention adopts rubber as encapsulant, and the distance between main shaft housing and the workpiece can be carried out adjustment among a small circle;
When (3) the present invention adopts gas that water is discharged drainage cover welding process is played the gas shield effect.
Description of drawings
Fig. 1 is structural representation of the present invention;
Among the figure: 1-workpiece, 2-sealing gasket, 3-cover body, 4-stopper attaching parts, 5-hydraulic cylinder body, 6-power transmission shaft, 7-spring bearing, 8-hydraulic cylinder piston, 9-hydraulic motor, 10-positive coupling, 11-stopper.
The specific embodiment
Illustrated by Fig. 1, a kind of local dry-type is the friction stitch welding device under water, wherein: the sealing gasket 2 that elastomeric material is made is connected on the cover body 3, cover body 3 is bolted hydraulic cylinder body 5 again, power transmission shaft 6 is connected to hydraulic motor 9 by shaft coupling, hydraulic motor 9 is bolted hydraulic cylinder body 5, and by spring bearing 7 location, the distance between main shaft housing and the workpiece 1 can be carried out adjustment among a small circle between power transmission shaft 6 and the hydraulic cylinder piston 8.
Before the welding beginning, this device is navigated to reasonable altitudes, guarantee to form certain sealing between sealing gasket 2 and the workpiece 1, then by in cover body 3, being filled with gases at high pressure water is discharged, form stable local dry-type welding environment, simultaneously welding process is played the gas shield effect; Then begin welding operation, hydraulic motor 9 at first drives stoppers 11 by power transmission shaft 6 and reaches the required rotating speed of welding, and the hydraulic cylinder epicoele is filled with the high pressure liquid force feed so that hydraulic cylinder piston 8 moves down according to the speed of welding requirements, until finish whole welding process.
