Specific embodiment
It is described in detail below in conjunction with accompanying drawing specific embodiment of this disclosure.It should be appreciated that this place is retouched
The specific embodiment stated is merely to illustrate and explains the disclosure, is not limited to the disclosure.
A kind of as depicted in figs. 1 and 2, welding tooling for bar shaped weldment of disclosure offer, including jig 10,
At least one fixture 20 and pre-load means 30, fixture 20 are arranged on jig 10 for fixed bar shaped weldment
81, pre-load means 30 are used to apply active force to the suspension end 812 of bar shaped weldment 81, so that bar shaped weldment 81 produces weldering
Connect reversal deformation.
Before welding, first bar shaped weldment 81 is placed on jig 10, makes the non-solder end of the bar shaped weldment 81
(that is, suspend end 812) is hanging, then clamps the welding ends 811 of bar shaped weldment 81 with fixture 20, then with pre-load means 30 to
The suspension end 812 of bar shaped weldment 81 applies active force, makes bar shaped weldment 81 (real in figure to the direction opposite with welding deformation
It is downward to apply example) produce predeformation (that is, welding anti-distortion).During welding, bar shaped weldment 81 produces welding deformation, and the welding becomes
Shape is cancelled out each other with above-mentioned welding anti-distortion so that the flexural deformation degree of bar shaped weldment 81 is in rational scope after the completion of welding
It is interior.The welding tooling of the disclosure produces welding reversal deformation to offset welding deformation by making bar shaped weldment 81, improves weldering
Quality is connect, the labour intensity of postwelding shaping is reduced.
Bar shaped weldment 81 is schematically illustrated in Fig. 1 and Fig. 2 in its rectangular block 82, second of welding ends 811 and first
