Background technique

In the lap joint patterns of the longitudinal beam welds of some existing off-road vehicles, the inner and outer longitudinal beams are stamped parts, generally with a thickness of 3.5mm; Other factors lead to the large opening size of the outer sheet of the longitudinal beam, which can only ensure that the weld gap between the inner and outer sheets of the longitudinal beam is ≤2.5mm and the consistency is poor. If the weld gap is not controlled during welding, the weld strength will not meet the process requirements. In order to control the weld gap to meet the design requirements, the existing method is generally to manually correct the opening of the outer sheet of the longitudinal beam, and use F clamps to control the non-conforming items after the inner and outer sheets of the longitudinal beam are buckled. problems such as local plastic deformation of edges.

Utility model content

Aiming at the problems existing in the background technology, the purpose of this utility model is to provide a box-type frame longitudinal beam flanging split correction that controls the weld gap size of the inner and outer sheets of the longitudinal beam within the range of 1±0.5mm and meets the size requirements of the welding process. device.

In order to achieve the above-mentioned purpose, the box-type vehicle frame longitudinal beam flanging split type correction device designed by the utility model is characterized in that: it includes a cylinder with two output ends that can be clamped oppositely, and each output end is connected to a connecting plate; The top of the connecting plate is detachably connected to a plurality of positioning clamping blocks at intervals; the positioning clamping block includes a clamping part, a vertical transition part and a horizontal connecting part, and the two ends of the vertical transition part are respectively connected to one end of the clamping part. It is connected with one end of the horizontal connecting part, and the horizontal connecting part is detachably connected with the connecting plate; the horizontal connecting part can slide along its length direction and height direction.

Preferably, the top of the connecting plate is provided with a groove for accommodating the horizontal connecting portion; one of the two opposite side walls perpendicular to the horizontal connecting portion of the groove is an open surface, and the other is provided with a waist-shaped hole ; The top surface of the horizontal connecting portion is also provided with a waist-shaped hole. In this way, the horizontal connecting part is detachably connected to the connecting plate through screws, and the waist-shaped hole is used to realize sliding along the length direction and height direction of the horizontal connecting part, that is, to realize the size adjustment of the positioning clamping block in the Y direction and Z direction .

Further preferably, a gasket is provided between the two connecting surfaces of the horizontal connecting portion and the groove. In this way, the accuracy and reliability of the connection is improved by the gasket.

Preferably, the top surface of the clamping part is provided with an anti-welding slag copper sheet.

The beneficial effects of the utility model are: the utility model can effectively control the lap welding seam gap of the inner and outer sheets of the longitudinal beam through the gasket and the waist-shaped hole according to the batch stamping parts, reduce the labor intensity of the workers, improve the work efficiency, and improve the box type. The quality of frame rail welding assembly.

detailed description

Below by means of Fig. 1～Fig. 4 and enumerating some optional embodiments of the present invention, the technical solution of the present utility model (including the preferred technical solution) is described in further detail, any technical features and any technical features in this embodiment All schemes do not limit the scope of protection of the present utility model.

As shown in Figure 1, the box-type frame longitudinal beam flanging split correction device designed by the utility model includes a cylinder 1 with two output ends that can be clamped oppositely, and each output end is connected to a connecting plate 2; The top of the connecting plate 2 is detachably connected to a plurality of positioning clamping blocks 3 at intervals.

As shown in Figure 3 and Figure 4, the positioning clamping block 3 includes a clamping part 3.1, a vertical transition part 3.2 and a horizontal connecting part 3.3, and the two ends of the vertical transition part 3.2 are connected to one end of the clamping part 3.1 respectively. It is connected to one end of the horizontal connecting part 3.3, and the horizontal connecting part 3.3 is detachably connected to the connecting plate 2; the horizontal connecting part 3.3 can slide along its length direction and height direction; the top surface of the horizontal connecting part 3.3 is also set Waist-shaped hole 4 is arranged.

As shown in Figure 2, the top of the connecting plate 2 is provided with a groove 2.1 for accommodating the horizontal connecting portion 3.3; one of the two opposite side walls perpendicular to the horizontal connecting portion 3.3 of the groove 2.1 is an opening surface 2.2, the other is provided with a waist-shaped hole 4. The length of the connecting plate 2 and the number of grooves 2.1 can be selected according to the quality of the longitudinal beam, that is to say, the number of positioning clamping blocks 3 is determined by the quality of the longitudinal beam.

The horizontal connecting part 3.3 is detachably connected to the connecting plate 2 through screws, and the waist-shaped hole 4 is used to slide along the length direction and the height direction of the horizontal connecting part 3.3, that is, to realize the positioning of the clamping block 3 in the Y direction and the Z direction. size adjustment.
