When a component is considered to be "connected" to another component, it can be directly connected to the other component or intervening components may also be present. When an element is referred to as being "disposed on" another element, it can be directly on the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like are used herein for illustrative purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs. The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.

The utility model is further illustrated by the following examples in conjunction with the accompanying drawings:

an apparatus for correcting welding deformation of oval pipes, as shown in fig. 1, comprises a bottom frame 1, an end clamping assembly 2 and a supporting deformation-preventing assembly 3.

The chassis 1 is internally provided with a through hole penetrating front and back. The underframe 1 can be manufactured by adopting square tube steel, so that the strength can be ensured, the weight can be reduced, and the hoisting or forklift can be conveniently transported and installed on relevant welding equipment.

The end clamping assemblies 2 are arranged at the front end and the rear end of the top of the underframe 1. The end clamping assembly 2 comprises a U-shaped supporting base 21, an n-shaped clamping top seat 22, an upper clamping plate 23 and a lower clamping plate 24, wherein the U-shaped supporting base 21 is fixed at the top of the underframe 1, arc-shaped clamping plates 25 are arranged on the inner sides of the U-shaped supporting base 21 and the n-shaped clamping top seat 22, an oval tube 4 to be welded is clamped between the U-shaped supporting base 21 and the n-shaped clamping top seat 22, the upper clamping plate 23 is positioned at the top of the n-shaped clamping top seat 22, the lower clamping plate 24 is positioned at the bottom of the underframe 1, and the upper clamping plate 23 and the lower clamping plate 24 are fixed through two clamping bolts 26 and nuts 27.

The two ends of the oval tube 4 are pre-clamped by the end clamping assembly 2, so that the oval tube is ensured to be stable in the welding process.

The supporting anti-deformation assembly 3 is arranged at the top of the underframe 1 and between the two end clamping assemblies 2, and is mainly positioned right below the welding part and uniformly arranged. The supporting deformation-preventing assembly 3 comprises a U-shaped frame 31 fixed on the top of the underframe 1, and an arc-shaped deformation-preventing plate 32 is arranged on the inner side of the U-shaped frame 31.

As shown in fig. 1, when the oval tube 4 is welded, the position of the top of the tube is mainly welded, and after welding, the shrinkage of the direction A1 and the direction A2 is generated, which may cause deformation, so that the plurality of groups of support anti-deformation assemblies 3 can provide a jacking force for the oval tube 4, so that serious deformation is avoided, and the product quality is affected.

The U-shaped supporting base 21 and the U-shaped frame 31 are detachably arranged on the top of the underframe 1 through bolts.

The upper clamping plate 23 is welded on top of the n-shaped clamping top seat 22.

The lower clamping plate 24 is welded at the bottom of the underframe 1.
