Abstract
The utility model relates to an automatic compensation device for shrinkage amount in electro beam welding. The automatic compensation device is characterized in that the automatic compensation device for the shrinkage amount in the electro beam welding comprises a disk spring, a shouldered nut, a locking nut, a stud, a support plate and a press plate, wherein the stud penetrates through the support plate and the press plate, the disk spring is sheathed on the stud and is positioned between the support plate and the press plate, the shouldered nut is used for compressing the support plate and is arranged on the stud, and the locking nut is arranged on the position of the stud and positioned at the outer surface of the shouldered nut. The automatic compensation device for the shrinkage amount in the electro beam welding has the advantages that the principle and the structure are simple, the welding shrinkage amount can be automatically compensated, the welding deformation is reduced or eliminated, and the welding quality is improved.
Description
Technical field
The utility model relates to mechanical structure field, particularly amount of contraction autocompensation installation in a kind of electron beam welding.
Background technology
In electron beam welding process in the past, due in the joint, along with the bombardment of high-power electron beam, metal melts gradually, and then produces certain amount of contraction, so can produce loosening phenomenon at clamping area, soldered part can't be compacted, and positioning states is also unstable, like this, directly cause welding deformation uncontrollable, thus the welding quality of having a strong impact on.
The utility model content
The purpose of this utility model is in order to realize real-time auto-compensation welding contracted quantity in welding process, and the spy provides amount of contraction autocompensation installation in a kind of electron beam welding.
The utility model provides amount of contraction autocompensation installation in a kind of electron beam welding, it is characterized in that: in described electron beam welding, the amount of contraction autocompensation installation comprises disk spring 1, band shoulder nut 2, locking nut 3, double-screw bolt 4, support plate 5, pressing plate 6;
Wherein: double-screw bolt 4 passes support plate 5 and pressing plate 6, and disk spring 1 is enclosed within on double-screw bolt 4, and between support plate 5 and pressing plate 6, band shoulder nut 2 compresses support plate 5 and is arranged on double-screw bolt 4, and locking nut 3 is arranged on the position that is positioned at band shoulder nut 2 outsides on double-screw bolt 4.
The quantity of described disk spring 1 is even number.
During welding, disk spring 1 is given certain pretightning force, and pretension decrement, pretension process turn band shoulder nut 2 to the appropriate location, then tightens locking nut 3 and get final product.In working order, on support plate 5, disk spring 1 is compressed when External Force Acting, produces decrement.In welding process, weld seam 8 places can produce amount of contraction, and pressing plate 6 also can tightly be pushed down workpiece under the effect of disk spring 1, and the decrement of disk spring 1 must be greater than welding contracted quantity.
Advantage of the present utility model:
Amount of contraction autocompensation installation in electron beam welding described in the utility model, theory structure is simple, can the auto-compensation welding contracted quantity, reduce or eliminate welding deformation, improve welding quality.
Description of drawings
Below in conjunction with drawings and the embodiments, the utility model is described in further detail:
Fig. 1 is amount of contraction autocompensation installation theory structure schematic diagram in electron beam welding.
The specific embodiment
The present embodiment provides amount of contraction autocompensation installation in a kind of electron beam welding, it is characterized in that: in described electron beam welding, the amount of contraction autocompensation installation comprises disk spring 1, band shoulder nut 2, locking nut 3, double-screw bolt 4, support plate 5, pressing plate 6;
Wherein: double-screw bolt 4 passes support plate 5 and pressing plate 6, and disk spring 1 is enclosed within on double-screw bolt 4, and between support plate 5 and pressing plate 6, band shoulder nut 2 compresses support plate 5 and is arranged on double-screw bolt 4, and locking nut 3 is arranged on the position that is positioned at band shoulder nut 2 outsides on double-screw bolt 4.
The quantity of disk spring 1 is even number.
During welding, disk spring 1 is given certain pretightning force, and pretension decrement, pretension process turn band shoulder nut 2 to the appropriate location, then tightens locking nut 3 and get final product.In working order, on support plate 5, disk spring 1 is compressed when External Force Acting, produces decrement.In welding process, weld seam 8 places can produce amount of contraction, and pressing plate 6 also can tightly be pushed down workpiece under the effect of disk spring 1, and the decrement of disk spring 1 must be greater than welding contracted quantity.
