Abstract
The utility model relates to a welding tool. The welding tool comprises a core rod, a conic body I and a conic body II, a central hole is formed in the center of the conic body I and the center of the conic body II, the thin end of the conic body I and the thin end of the conic body II are arranged in centering holes of two workpieces to be welded respectively, the core rod penetrates through the central hole of the conic body I and the conic body II, and a gasket and a nut are used for fixing the conic body I, the conic body II and the two workpieces together. The thin end of the conic body I and the thin end of the conic body II are arranged in the centering holes of the two workpieces to be welded respectively, the welding tool can adapt to different hole diameters, the centering holes of the two workpieces to be welded can be always guaranteed to be concentric, the whole operation is simple, and the welding tool can be suitable for centering of different hole diameters.
Description
Technical field
The utility model relates to a kind of welding tooling.
Background technology
When being provided with two workpiece welding of perforate, concentric for the hole that guarantees two workpiece, often need to make the bearing pin frock.During welding, bearing pin is inserted in the corresponding hole, by bearing pin centering is carried out in the hole, because bearing pin must be complementary with corresponding hole, all need to make different bearing pins when therefore different workpiece welds, like this, not only waste Production Time, and consume material.
The utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of welding tooling that guarantees that the hole is concentric.
The technical solution of the utility model is: it comprises plug, cone I, cone II, the center of described cone I and cone II is provided with centre bore, the taper end of cone I and cone II place respectively two workpiece to be welded to mesopore, plug passes in the centre bore of cone I and cone II and with pad and nut cone I, cone II and two workpiece is fixed together.
One end and the cone I of described plug are fixed together, and the other end of plug is provided with screw thread.
Effect of the present utility model is, with the taper end of cone I and cone II place respectively two workpiece to be welded to mesopore, not only can adapt to different pore size, and can guarantee all the time the concentric to mesopore of two workpiece to be welded, whole simple to operate, and can be suitable for the centering of different pore size.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Wherein, 1, plug; 2, cone I; 3, cone II; 4, pad; 5, nut; 6, workpiece I; 7, workpiece II; 8, to the mesopore I; 9, to the mesopore II; 10, centre bore.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model comprises plug 1, cone I 2, cone II 3, the center of cone I 2 and cone II 3 is provided with centre bore 10, the lower end of plug 1 and cone I 2 are fixed together, the upper end of plug 1 is provided with screw thread, the taper end of cone I 2 and cone II 3 place respectively workpiece II 7 to be welded to mesopore II 9 and workpiece I 6 to be welded to mesopore I 8, plug 1 passes in the centre bore 10 of cone I 2 and cone II 3, and by pad 4 fastening nuts 5, can be with cone I 2, cone II 3, workpiece I 6 and workpiece II 7 are fixed together.
With the taper end of cone I 2 and cone II 3 place respectively workpiece II 7 to be welded to mesopore II 9 and workpiece I 6 to be welded to mesopore I 8, not only can adapt to the workpiece centering welding of different pore size, and can guarantee all the time the concentric to mesopore of two workpiece to be welded, whole simple to operate, and can be suitable for the workpiece centering of different pore size.
More than be a kind of embodiment of the present utility model, a preferred demonstration example.The scope that the utility model application is asked for protection has more than and is limited to described embodiment.The technical scheme of all and the present embodiment equivalence all belongs to protection domain of the present utility model.
