BACKGROUND

[0002] In the past, when bolted box beam steel member was manufactured, the box-shaped rod was first disassembled into horizontal plates and vertical plates, and then the bolt holes on the parts were drilled by using the "first hole method" process with numerical control drilling machine. After the parts were detected and qualified, they were ready for assembly. The commonly used assembly process is as follows: the qualified parts are assembled on a special platform, the vertical plate assembly positioning line is first scribed on the horizontal plate (the scribing accuracy deviation must meet the technical requirements), and then the vertical plate is assembled according to the line, the rough alignment is performed by using a hoisting crane and manual work, the vertical plate is fixed by using positioning weld after fine adjustment, and the temporary angle horse plate is used to ensure the assembly perpendicularity of the horizontal plate and the vertical plate, and finally the welding is performed. The disadvantages of this method are: the positioning line must be scribed on the horizontal plate, and the temporary horse plate must be used for positioning and welding during assembly, which requires professional skills for scribing and welding, and the manpower and time investment is large, and the temporary weld polishing work is increased, so the overall assembly efficiency is low. SUMMARY

[0003] Design purpose: to avoid the disadvantages in the background art, a bolted box joint assembly auxiliary device is designed, which can optimize and merge the works such as scribing, positioning, temporary horse plate, welding and polishing, and can concentrate various processes and functions in one device, so that the work can be completed at one time.

[0004] Design scheme: in order to achieve the above design purpose, the horizontal plate and the vertical plate of the device are designed according to the design hole group module on the bolted box member, the hole spacing a and b values on the horizontal plate and the vertical plate are determined, and finally the horizontal plate and the vertical plate are determined. The horizontal plate and the vertical plate are made by using high-precision method according to the design size, and the corner stiffener, handheld stiffener, precision positioning punch, finished bolt, ruler and wrench are prepared.

[0005] The horizontal plate, the vertical plate, the corner stiffener and the handheld stiffener are precisely assembled and welded into a whole, the finished bolt is screwed into the threaded hole after ensuring that the perpendicularity meets the requirements, and the size is accurately adjusted according to the joint hole position. After the device is positioned firmly with the joint horizontal plate by using the positioning punch, the vertical positioning size is adjusted by repeating the above process, and the joint vertical plate is positioned firmly by using the punch. All positioning work of the four corners of the box joint is completed by repeating the above steps.

[0006] The utility model discloses compared with the background art, first, the optimization of the plurality of processes in the previous process is combined, and it is centralized in one, and the one-time operation is completed, reduces the process circulation, guarantees the manufacturing precision, improves the manufacturing efficiency, second, through the bolt hole of the first hole method drilling of the bolted box type component, the quick assembly of each plate piece, the accurate positioning can be realized, the manufacturing process is reduced, and the effect of reducing cost and increasing efficiency is played, third, the design is light and clever, has the characteristics such as simple operation, portable use, wide application range, and the characteristics of being reusable, and a kind of solution is proposed for similar bolted steel bridge bar production.
