[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] As a preferred embodiment of the IGA assembly welding correction device of the utility model, Figure 1-Figure 4As shown, this embodiment provides an IGA component welding correction device, including a base 1, a plurality of inverted T-shaped mounting grooves 2 are arranged in parallel on the base 1, a plurality of stands 3 are connected to the base 1, a screw 4 is vertically connected to the top of the stand 3, a pressing block 5 is threadedly connected to the screw 4, and the plurality of stands 3 are used to install the IGA components; and also includes a door frame 6, the door frame 6 is installed on the base 1, the door frame 6 includes two columns 7 and a crossbeam 8 welded between the two columns 7, a walking trolley 9 is provided on the crossbeam 8, and the walking trolley 9 is provided on the crossbeam 8. The trolley 9 is driven by a motor 10 to move on the beam 8. An automatic hydraulic cylinder 11 is connected to the bottom of the trolley 9. During correction, the motor 10 drives the trolley 9 to move left and right on the beam, and then the automatic hydraulic cylinder 11 is started to correct the part that needs correction. The maximum thrust of the automatic hydraulic cylinder 11 is not less than 120 tons. According to empirical statistics, when the maximum thrust of the automatic hydraulic cylinder 11 is between 120 tons and 160 tons, it can meet the requirements of plane correction and ensure correction efficiency. A 150-ton LAF jack is preferred.

[0021] It should be noted that the hydraulic cylinder in the present invention must be equipped with a hydraulic station. This is common knowledge in hydraulic system technology. Since this application does not elaborate on this part, the hydraulic station can be installed on the crossbeam.

[0022] In some preferred embodiments, Figure 2 and Figure 5 As shown, Figure 5 A in the middle is an IGA component. Since the IGA component is large and heavy, the stability of the clamping of the IGA component must be ensured during the calibration process to prevent the IGA component from moving during the calibration process. In this case, it is difficult to clamp the IGA component again. Therefore, in this embodiment, the tracks formed by the multiple stands 3 are on a circular track. In this way, the IGA component can be firmly fixed in a complete circumferential direction, providing technical guarantee for subsequent efficient calibration.

[0023] In some preferred embodiments, Figure 2 As shown, it also includes a manual screw jack 12, which is separately arranged from the crossbeam 8. The main function of the manual screw jack 12 is to prevent excessive correction caused by the automatic hydraulic cylinder 11 when the correction requires a smaller thrust. At the same time, in order to facilitate adjustment during the correction process, the manual screw jack 12 can be flexibly moved and placed, and the maximum thrust of the manual screw jack 12 can be selected to be about 20 tons.

[0024] In some preferred embodiments, considering that according to the need for correction, the portal frame may need to be moved to adjust the correction position, based on this, such as Figure 1 and Figure 4 As shown, in this embodiment, the two uprights 7 of the portal frame 6 are detachably connected to the base 1 through a clamping rod assembly, and the clamping rod assembly includes a threaded rod 13, the bottom end of which is fixedly connected to a fixing block 14, and also includes a pressing block 15 threadedly connected to the threaded rod 13 and a nut 16 connected to the threaded rod 13, wherein the nut 16 is located on the outside of the pressing block, so that the connection position of the portal frame on the base 1 can be adjusted, thereby more flexibly adjusting the relative position of the portal frame and the IGA assembly, which is convenient for efficient correction.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
