Description

Technical Field

[0001] This utility model relates to the field of welding tooling technology, specifically a U-rib assembly tooling. Background Technology

[0002] In some planar steel structural panels, reinforcing ribs are typically welded to the surface to increase structural strength. Patent CN102275026A discloses a welding process for U-ribs in steel bridge deck panels, including the following steps: First, the two ends of the U-rib are placed at the welding positions on the steel bridge deck. Second, a gas-shielded welding head is used to perform gas-shielded welding on the welding positions, while a submerged arc welding head is used to perform automatic submerged arc welding on the welding positions at the rear. Therefore, with a U-rib plate thickness of 12mm, a weld penetration rate of 80%-100% is achieved. However, when welding the plate surface and the reinforcing ribs, since the reinforcing ribs are generally placed directly on the plate surface, their positions are prone to stress deviation, resulting in dimensional errors in the weld and affecting the quality of the final product. Therefore, improvements are needed. Utility Model Content

[0003] The purpose of this utility model is to provide a U-rib assembly tooling, which solves the problem that when welding the plate surface and the reinforcing rib, since the reinforcing rib is generally placed directly on the plate surface, the positions of the two are prone to force deviation, resulting in welding dimensional errors and affecting the quality of the final product.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a U-rib assembly tooling, including a base, a support column fixedly connected to the upper edge of the base, a crossbeam welded to the top of the support column, a support rib welded to the middle of the upper end of the base, a road panel placed on the top of the support rib, a U-shaped rib placed on the top of the road panel, an adjusting screw threadedly connected to the inside of the crossbeam, the adjusting screw passing through the crossbeam, a retaining sleeve rotatably connected to the lower end of the adjusting screw, the retaining sleeve engaging with the U-shaped rib, and the retaining sleeve abutting against the road panel.

[0005] Preferably, the upper section of the adjusting screw is threadedly connected to a locking nut, and the locking nut abuts against the crossbeam. The locking nut prevents the adjusting screw from loosening.

[0006] Preferably, the top of the crossbeam is welded with lifting lugs, and the lifting lugs have through holes inside. The lifting lugs facilitate the overall lifting and transportation.

[0007] Preferably, a guide rod is fixedly connected to the upper edge of the ferrule, and a guide sleeve is threadedly connected to the bottom of the crossbeam. The guide sleeve passes through the crossbeam, and the guide rod passes through the guide sleeve and is slidably connected to it. The guide rod and guide sleeve provide guidance for the lifting and lowering of the ferrule.

[0008] Preferably, the inner wall of the guide sleeve is provided with balls, and the balls are in contact with the guide rod. By providing balls, the relative friction between the guide rod and the guide sleeve can be reduced.

[0009] Preferably, a limiting ring is fixedly connected to the lower outer part of the guide sleeve, and a locking pin is slidably connected inside the limiting ring. The locking pin engages with the crossbeam, and a spring is provided inside the limiting ring. One end of the spring is fixedly connected to the locking pin, and the other end of the spring is fixedly connected to the inner surface of the limiting ring. The spring force acts on the locking pin, thereby preventing loosening of the limiting ring and the guide sleeve.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This utility model features a base for supporting the road panel, with a crossbeam mounted above the base. A retainer is installed on the crossbeam for adjustable lifting via a screw. The retainer can also be guided by a guide sleeve and a guide rod. This allows the welding positions of the U-shaped ribs to be fixed after they are placed on the road panel, ensuring the accuracy of the workpiece dimensions and reducing welding errors.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3 A U-rib assembly tooling includes a base 1, a support column 2 fixedly connected to the upper edge of the base 1, a crossbeam 3 welded to the top of the support column 2, a support rib 4 welded to the middle of the upper end of the base 1, a road panel 5 placed on top of the support rib 4, and a U-shaped rib 6 placed on top of the road panel 5. An adjusting screw 7 is threadedly connected to the inside of the crossbeam 3, and the adjusting screw 7 passes through the crossbeam 3. A retaining sleeve 8 is rotatably connected to the lower end of the adjusting screw 7, engaging with the U-shaped rib 6 and abutting against the road panel 5. A locking nut 9 is threadedly connected to the upper section of the adjusting screw 7, and the locking nut 9 abuts against the crossbeam 3. The locking nut 9 prevents the adjusting screw 7 from loosening. A lifting lug 16 is welded to the top of the crossbeam 3, and the lifting lug 16 has a through hole. The lifting lug 16 facilitates the overall lifting and transportation.

[0019] Please see Figure 3-4 A guide rod 10 is fixedly connected to the upper edge of the ferrule 8, and a guide sleeve 11 is threadedly connected to the bottom of the crossbeam 3. The guide sleeve 11 passes through the crossbeam 3, and the guide rod 10 passes through the guide sleeve 11 and is slidably connected to it. The guide rod 10 and guide sleeve 11 guide the lifting and lowering of the ferrule 8. A ball bearing 12 is provided on the inner wall of the guide sleeve 11, and the ball bearing 12 contacts the guide rod 10. The ball bearing 12 reduces the relative friction between the guide rod 10 and the guide sleeve 11.

[0020] Please see Figure 4 A limiting ring 13 is fixedly connected to the lower outer part of the guide sleeve 11. A locking pin 14 is slidably connected inside the limiting ring 13, and the locking pin 14 engages with the crossbeam 3. A spring 15 is provided inside the limiting ring 13. One end of the spring 15 is fixedly connected to the locking pin 14, and the other end of the spring 15 is fixedly connected to the inner surface of the limiting ring 13. The elastic force of the spring 15 acts on the locking pin 14, thereby preventing the limiting ring 13 and the guide sleeve 11 from loosening.

[0021] The specific implementation process of this utility model is as follows: In use, firstly, the road panel 5 is placed on the support rib 4 of the base 1, and then each U-shaped rib 6 is placed on the road panel 5 in sequence. Then, the adjusting screw 7 is turned. The adjusting screw 7 generates an axial downward position through the threaded movement between it and the crossbeam 3. Then, the ferrule 8 will move downward under the guidance of the guide sleeve 11 and the guide rod 10 and be locked on the outside of the U-shaped rib 6, thereby fixing the welding position of the U-shaped rib 6, thus ensuring the accuracy of the workpiece dimensions and reducing welding errors.
