Description

Technical Field

[0001] The utility model relates to the technical field of machining, in particular to a device for correcting an intermediate section of a main beam rib plate. Background Art

[0002] During routine rib plate splicing in the workshop, the middle section of the rib plate will warp due to plate cutting. The warping of the rib plate will affect the subsequent splicing and welding operations. In order to ensure the flatness of the subsequent rib plate welding, the staff is required to perform horizontal correction on the warped part of the rib plate. The commonly used correction method is that the staff manually uses a tilting rod to correct the deformed middle section of the rib plate. This method of horizontal correction of the middle section of the rib plate not only requires the collaborative work of multiple staff members, but is also time-consuming and labor-intensive, and the safety cannot be guaranteed. In addition, in the subsequent rib plate welding process, since the rib plate cannot be effectively limited and fixed, the rib plate is prone to displacement during the welding process, and the surface flatness of the rib plate after welding cannot be effectively guaranteed.

[0025] Please refer to the instruction manual Figure 1-4 , the utility model provides a technical solution:

[0026] Embodiment 1, a device for correcting the intermediate section of the main beam rib plate, comprises a bottom plate 1, a vertical rod 3 is provided on one side of the bottom plate 1, a horizontal rod 4 is provided on the upper end of the vertical rod 3 and is located on the upper surface of the bottom plate 1 and parallel to the bottom plate 1, a movable block 7 which can slide and adjust along the axial direction of the horizontal rod 4 is provided on one side of the horizontal rod 4, specifically, a slide groove 12 is provided on the side surface of one side of the horizontal rod 4 along the axial direction of the horizontal rod 4, the movable block 7 is slidably matched with the slide groove 12, a driving mechanism 8 for driving the movable block 7 to slide along the axial direction of the slide groove 12 is provided in the slide groove 12, the driving mechanism 8 comprises a screw rod 11 and a turning handle 10, a screw rod 11 which is axially arranged in the eye slide groove 12 is rotatably installed in the slide groove 12, a screw hole 16 which penetrates the movable block 7 and is threadedly matched with the screw rod 11 is provided on the movable block 7, one end of the screw rod 11 penetrates the slide groove 12, and a turning handle 10 is provided at its end;

[0027] A pressing member 6 which can move synchronously with the movable block 7 and can be adjusted up and down is provided on one side of the movable block 7 facing the notch of the slide slot 12. Specifically, the pressing member 6 includes a nut 17 and a screw rod 15. The nut 17 is fixedly connected to the movable block 7. The central axis of the nut 17 is perpendicular to the bottom plate 1. The screw rod 15 is connected to the inner thread of the nut 17. A through hole 13 penetrating the screw rod 15 is provided on one side of the upper end of the screw rod 15 located at the upper part of the nut 17. A rotating rod 14 for rotating the screw 15 is provided in the through hole 13. An expanding head is provided at one end of the rotating rod 14. A pressing plate 9 for flattening the warped part of the rib plate is provided at the lower end of the screw rod 15 located at the lower part of the nut 17.

[0028] A longitudinal limiting rod 2 is provided on the side of the upper surface of the bottom plate 1 close to the vertical rod 3 and is parallel to the bottom plate 1 and is used to limit and block the rib plate. The longitudinal limiting rod 2 and the cross bar 4 are perpendicular to each other. A transverse limiting rod 5 is provided on the side of the longitudinal limiting rod 2 facing away from the vertical rod 3 and is perpendicular to the longitudinal limiting rod 2 and can be adjusted along the axial direction of the longitudinal limiting rod 2. Specifically, a side surface of the longitudinal limiting rod 2 facing away from the vertical rod 3 is provided with a plurality of insertion holes 23 arranged in an orderly manner along the axial direction of the longitudinal limiting rod 2, and one end of the transverse limiting rod 5 is provided with an insertion rod 24 adapted to the insertion hole 23;

[0029] During the horizontal correction of the rib plate and the subsequent welding of multiple rib plates, since the position of the cross bar 4 is fixed, the pressure plate 9 can only be moved and adjusted along the axial direction of the cross bar 4. In order to ensure that the pressure plate 9 can accurately press and calibrate the warped part of the rib plate, the rib plate is first placed on the upper part of the bottom plate 1, and one side of the rib plate is in contact with the longitudinal limit rod 2, and then the warped part of the rib plate is observed. If the warped part of the rib plate is located on the upper or lower side of the pressure plate 9, the staff can move the transverse limit rod 5 upward or downward to a suitable position and then contact the longitudinal limit rod 2. The rod 2 is plugged in and fixed, and the longitudinal limit rod 2 and the transverse limit rod 5 are used to limit the rib plate, which not only ensures that the warped part of the rib plate is within the movable range of the pressure plate 9, but also ensures the stability of the rib plate during the subsequent horizontal correction or welding process. After the rib plate is clamped, the staff can drive the movable block 7 to adjust the position of the pressure plate 9 by rotating the handle 10, so that the pressure plate 9 moves to above the warped part of the rib plate. The staff then rotates the screw 15 through the rotating rod 14, and uses the screw 15 to drive the pressure plate 9 to perform horizontal correction on the warped part of the rib plate.

[0030] In the second embodiment, when the pressing plate performs horizontal correction on the warped part of the rib plate, as the pressing plate 9 is pressed down to the upper part of the rib plate, it is very likely that the pressing plate and the warped part will not correspond. If the contact force between the pressing plate 9 and the rib plate is too large, the staff cannot directly drive the movable block 7 to move. At this time, the staff needs to raise the pressing plate 9 again to make adjustments. In order to facilitate the adjustment of the staff, the lower end of the screw rod 15 is provided with a movable rod 21 that can be slidably adjusted along the axial direction of the screw rod 15. Specifically, the lower end surface of the screw 15 is provided with a movable groove 19 arranged along the axial direction of the screw 15, and the notch of the movable groove 19 is provided with a reduced diameter port that matches the diameter of the movable rod 21. 22, the upper end of the movable rod 21 is inserted into the movable groove 19 through the reduced diameter opening 22, and the upper end of the movable rod 21 located in the movable groove 19 is provided with an enlarged diameter end 20 that matches the clearance of the inner wall of the movable groove 19, and the pressing plate 9 is fixedly installed at the lower end of the movable rod 21, and the screw 15 between the nut 17 and the pressing plate 9 and the rod body of the movable rod 21 are sleeved with a spring 18. By utilizing the elastic support of the spring 18, the enlarged diameter end 20 at the upper end of the movable rod 21 is in conflict with the reduced diameter opening 22. When the pressing plate 9 contacts the rib plate and is found to be misaligned with the warped part, the elastic force of the spring 18 and the sliding of the movable rod 21 can be used to directly drive the movable block 7 to drive the lower pressing piece 6 and the pressing plate 9 to move;

[0031] In addition, during the horizontal correction of the warped part, the staff drives the screw 15 to move downward in a spiral. As the pressure plate 9 comes into contact with the warped part of the rib plate, the movable rod 21 also slides upward. When the expanded end 20 moves to the inner bottom surface of the movable groove 19, the staff continues to drive the screw 15 to move downward in a spiral, thereby applying sufficient pressure to the warped part of the rib plate. Coupled with the elastic force of the spring 18 after contraction, the horizontal correction effect of the pressure plate 9 on the warped part of the rib plate can be greatly improved.

It is obvious to those skilled in the art that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.
