A welding tool for a curved arm beam is characterized in that a bend is formed in the middle of the curved arm beam, a plurality of pin shafts are connected to the middle and two ends of the curved arm beam in a penetrating mode, the welding tool comprises a bottom support, a cambered surface rack which is supported on the bottom surface of the curved arm beam in a matched mode is fixedly arranged in the middle of the bottom support, a plurality of groups of shaft supports which are used for positioning clamping the curved arm beam and radially supporting the pin shafts are fixedly arranged on the bottom support in an opposite mode, and a top supporting plate is fixedly arranged on one side of the bottom support in a vertical direction; the top supporting plate is connected with a plurality of bolt supporting pieces which are supported on the side wall of the curved arm beam in a penetrating way.
And the axle supports are symmetrically and fixedly arranged on the bottom supports at the two sides of the cambered surface rack, and the top parts of the axle supports are provided with U-shaped brackets which are matched with the supporting pin shafts and have openings at the top parts.
And the shaft support comprises a middle shaft support and an end shaft support, wherein the middle shaft support is Y-shaped, and two ends of the top of the middle shaft support are radially supported on the pin shafts in the middle of the bent arm beam and at the top of the bent arm beam respectively.
Moreover, the two sides of the cambered surface rack are made into planes, the distance between the two sides of the cambered surface rack is smaller than the distance between the two sides of the curved beam, and the top surface of the cambered surface rack is made into an arc surface.
The utility model has the advantages and the technical effect be:
the utility model discloses a welding frock of curved boom roof beam, provide the main part of welding frock through the collet to support, the cambered surface rack on the collet is with the arcwall face that its top was made, paste the tight fit on curved bottom surface of curved boom roof beam, with the axle bracket respectively radial support curved boom roof beam top, middle part and the round pin axle at both ends, and in order to avoid the flat deformation that welding stress leads to after the welding is accomplished, can push up the lateral wall of tight curved boom roof beam in side through the bolt jack piece; and the demoulding is convenient after the welding is finished, and the integral hoisting is finished and the beam welding assembly is completed.
