[0006] The cross section of the cross groove is a T-shaped slide groove, the cross section of the slide seat at the bottom of the slider is a T-shaped seat, and the T-shaped seat slides in the T-shaped slide groove.

[0007] The cross grooves are arranged to cross at any angle or to cross orthogonally.

[0008] The cross grooves shown are two or more crossing grooves.

[0009] The base is clamped in a vise.

[0010] The angle formed by the adapter and the flange hole on the flange circumference is adjusted by a wrench before welding.

[0011] The diameter and length of the threaded pin match the hole diameter and thickness of the flange to be installed.

[0012] Compared with the prior art, the utility model has the following beneficial technical effects:

[0013] The slider of the utility model slides relative to the groove of the base, and the threaded pin also moves with it. By adjusting the size, height and depth of the internal groove of the base and the slider, it can adapt to the correction of flanges of different sizes, thicknesses and angles. The flange to be corrected and the base are assembled together through the pins on the slider. The diameter and length of the threaded pin are used to adapt to flanges of different mounting hole diameters and thicknesses. Through the positioning of the base and the slider, flanges of different sizes can be corrected, and welding can be completed in one time with qualified angles and sizes. In addition, it avoids deformation of the flange after welding due to correction tooling and later repair work, thereby improving the correction efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited to the accompanying drawings and specific embodiments.

[0022] Figure 1 This is a three-dimensional structural diagram of the correction tooling of the utility model. Figure 2 It is a structural schematic diagram of the base of the utility model. Figure 3 This is a schematic diagram of the structure of the slider of the utility model. Figure 4 This is a schematic diagram of the structure of the threaded pin of the utility model, as shown in the figure: Example

[0023] The utility model correction tool is used for correcting the angle formed when the flange 4 and the adapter 5 are welded, and comprises a base 3, a slider 2 and a threaded pin 3; the base 1 is clamped by a vise, a cross groove 11 is provided on the base 1, and the cross groove 11 is arranged as two orthogonal crosses; the bottom of the slider 2 is a slide seat, the cross section of the cross groove 11 is a T-shaped slide groove 12, and the cross section of the slide seat at the bottom of the slider 2 is a T-shaped seat 21, and the T-shaped seat 21 slides in the T-shaped slide groove 12.

[0024] A pin hole 22 is provided on the upper part of the slider 2, and the bottom of the threaded pin 3 is threaded and installed in cooperation with the threaded hole. The diameter and length of the threaded pin 3 match the aperture and thickness of the flange 4 to be installed. The slider 2 includes four pieces, which are installed on the base 3 and correspondingly positioned with the mounting holes on the circumference of the flange 4, and the center hole of the flange 4 is installed with the adapter 5 to be welded.

[0025] The angle formed by the adapter 5 and the flange holes on the circumference of the flange 4 is adjusted by a wrench before welding. Example

[0026] The difference from the first embodiment is that a plurality of cross grooves 11 are arranged crosswise at any angle.

[0027] Figure 5 This is a schematic diagram of the installation and correction of the flange and adapter to be welded in the utility model. Figure 6 This is a top view of the installation and correction of the flange and adapter to be welded in the utility model, as shown in the figure:
