Abstract
The utility model relates to a kind of gas shield device that is used for high-temperature region Titanium Laser Welding two dimension composite curve weld seam.Welded sleeve 1 and gas hood 2 are rigidly connected with screw, and gas hood 2 is connected with rotary gemel 10 with the below of gas hood 4, and the top is connected by telescopic cover 3; Gas hood 4 is connected by rotary gemel 12 with the below of gas hood 6, and the top is linked to each other by telescopic cover 5; The lower cover 13,11 and 9 of fixed band gas outlet 8 is divided in gas hood 2,4 and 6 bottom, and the rear end of gas hood 6 has air inlet 7.The utility model adopts telescopic cover and hinge structure combining; making in the welding of large thin-wall element profile drags the motion of cover to do curvilinear motion with the curved surface of welded part with plumb joint; protection drags cover to change with the variation of two-dimentional each section of composite curve weld seam radius of curvature when the two-dimentional composite curve weld seam of welding, and the All Ranges that needs protection is effectively protected.
Description
Technical field
The utility model relates to a kind of gas shield device that is used for high-temperature region Titanium Laser Welding two dimension composite curve weld seam.
Background technology
Laser weld is a kind of advanced person's a connection technology, and advantage such as have the speed of welding height, welding quality is good, welding deformation is little and can carry out under atmospheric environment has very big advantage aspect the welding of large titanium alloy thin-wall part profile commonly used in the aviation manufacturing.Because titanium alloy at high temperature (more than 200 ℃) has strong absorption to airborne hydrogen, oxygen, nitrogen; therefore in the Titanium Laser Welding process; strict inert gas shielding measure generally need be taked in the welding high-temperature region; high-temperature area to welding pool, weld seam front and back of weld is protected, and invades the deterioration that weld seam causes Weld Performance to prevent hydrogen in the air, oxygen, nitrogen.The mode of safeguard measure protection is to adopt coaxial gas shiled welding pool respectively, again with dragging the positive high-temperature region of cover protection weld seam and design air drain protection back of weld high-temperature region on weld jig.Dragging cover is to connect a rigidity gas hood below welding enclosure, and the hollow cover body that gas hood is as a whole, gas hood are followed the plumb joint motion.But because gas hood is the integral body of a rigidity, protection drags cover not change with the variation of two-dimentional each section of composite curve weld seam radius of curvature when the two-dimentional composite curve weld seam of welding, can not effectively protect the All Ranges that needs protection.
Summary of the invention
The purpose of this utility model provides a kind of two-dimentional composite curve weld seam gas shield device that can change with the variation of two-dimentional each section of composite curve weld seam radius of curvature when the two-dimentional composite curve weld seam of welding.Technical solution of the present utility model is, welded sleeve 1 and gas hood 2 are rigidly connected with screw, and gas hood 2 is connected with rotary gemel 10 with the below of gas hood 4, and the top is connected by telescopic cover 3; Gas hood 4 is connected by rotary gemel 12 with the below of gas hood 6, and the top is linked to each other by telescopic cover 5; The lower cover 13,11 and 9 of fixed band gas outlet 8 is divided in gas hood 2,4 and 6 bottom, and the rear end of gas hood 6 has air inlet 7.The utility model adopts telescopic cover and hinge structure combining; making in the welding of large thin-wall element profile drags the motion of cover to do curvilinear motion with the curved surface of welded part with plumb joint; protection drags cover to change with the variation of two-dimentional each section of composite curve weld seam radius of curvature when the two-dimentional composite curve weld seam of welding, and the All Ranges that needs protection is effectively protected.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Curved surface difference according to welded part, gas hood can be divided into multistage, and existing is example with three sections gas hoods only, and it is one that an end of welded sleeve 1 and gas hood 2 is rigidly connected with screw, the below of the other end of gas hood 2 is connected with rotary gemel 10 with the below of gas hood 4, and the top is connected by telescopic cover 3; The below of the other end of gas hood 4 is connected by rotary gemel 12 with the below of gas hood 6, and the top is linked to each other by telescopic cover 5; The bottom of gas hood 2, gas hood 4 and gas hood 6 is the lower cover 13,11 and 9 of fixed band gas outlet 8 respectively, and the rear end of gas hood 6 has air inlet 7.
