Description
Technical Field
The utility model relates to a hoisting equipment makes the field, especially relates to a vehicular landing leg case processing frock.
Background
The supporting leg box is used as a key part of the crane to determine the stability and the safety of the crane during operation, the supporting leg box is formed by welding four vertical plates of a bottom plate, two webs perpendicular to the bottom plate and a cover plate, the method generally adopted during welding of the supporting leg box is that the bottom plate is laid on a corresponding workbench, then the installation positions of the vertical plates are marked by lines on the bottom plate according to the design size, the vertical plates are pre-fixed on the bottom plate in a spot welding mode according to the line marks, in the pre-fixing process, the perpendicularity of the vertical plates and the bottom plate is controlled by using a square, and meanwhile, an intermediate positioning part is arranged between every two adjacent vertical plates to restrain the distance between every two adjacent vertical plates.
In the prior art, CN202021823958.8 discloses a leg box welding tool, and the upper end of a base is provided with a positioning support surface for placing a bottom plate; two positioning pieces are arranged at intervals along the left and right direction, each positioning piece is provided with a vertical plate positioning clamping surface and a bottom plate positioning clamping surface which have set intervals in the left and right direction, the middle positioning body is placed on the bottom plate of the leg box to support the corresponding vertical plate, and the supporting surface at the upper end supports the cover plate; under the action of the clamping mechanism, the two positioning parts are matched with the clamping bottom plate and the two middle positioning bodies to clamp the vertical plates. The utility model discloses a though can make welding process need not manual measurement and rule location, ensure that the landing leg case after the welding has higher size precision, still have following problem:
1) And the positioning body is adopted for positioning, and after the welding of the web plate and the bottom plate is finished, the welding seam is cooled to reduce the distance between the component plates, so that the positioning body is clamped and is difficult to take out.
2) When longer landing leg case welding, because the middle part does not have the support to warp sunken easily, moreover, the assembly clearance of landing leg and landing leg case is often very little, and during the landing leg installation, the size of landing leg case probably does not match with the size of landing leg, if directly when assembling the landing leg case with the landing leg, probably causes the lateral wall wearing and tearing of landing leg case, falls the condition such as lacquer, influences the support stability of landing leg.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model aims at providing a vehicular landing leg case processing frock fixes a position the riser of landing leg case through adopting outer location frock and interior child mould cooperation to utilize the relative displacement of interior child mould crossbeam to make the setting element can be at landing leg incasement rotation, thereby prevent that the welding back interval from reducing, the condition that leads to the intervalve location body is pressed from both sides tightly and is difficult to take out takes place.
The utility model provides a technical scheme that its technical problem adopted is:
the utility model provides a vehicular landing leg case processing frock includes: the outer positioning tool comprises a base, a left positioning arm, a right jacking arm and an upper jacking arm; the left positioning arm and the right top bracing arm are arranged on the base in parallel, the upper top bracing arm is arranged above the space between the left positioning arm and the right top bracing arm, and the inner tire mold is arranged inside the leg box and matched with an outer positioning tool arranged outside the leg box to fix a vertical plate of the leg box;
