Description

Accurate positioning device for flat steel for welding steel grating Technical Field The invention belongs to the technical field of steel grating welding, and particularly relates to a flat steel accurate positioning device for steel grating welding. Background The steel grating is an open steel member formed by orthogonally combining bearing flat steel and cross bars at a certain interval and fixing the bearing flat steel and the cross bars by means of welding and the like. Because of the unique structure, the novel water-saving type water-saving device integrates the advantages of high strength, light weight, ventilation, light transmission, water drainage, skid resistance, simplicity and convenience in installation, attractive appearance, durability and the like, and is widely applied to various industrial fields. Currently, operators in the industry generally place flat steels on a workbench of a welding machine one by experience according to center distances (such as 30mm, 40mm and the like) of the flat steels required by orders, and measure one by one and manually adjust the flat steels by using calipers or simple spacing blocks. This method relies on the skill of the worker and is a traditional production model. The manual caliper measurement mode is easy to generate vision and operation errors, and accurate unification of the distance between each flat steel in mass production is difficult to ensure. The simple baffle device is easy to wear or loosen after being frequently used, the stop block is easy to wear or loosen, only one end of the flat steel is positioned, the other end of the flat steel is easy to deviate or twist in the placing process, the flat steel is not parallel, the appearance of a finished product of the steel grating plate and the uniformity of load distribution are finally affected, no matter the flat steel is purely manual or by means of the simple baffle, each flat steel needs to be placed, aligned and confirmed one by one, the working procedure is complex, and time and labor are consumed. Particularly, when a large-scale and multi-specification order is produced, the positioning device is frequently replaced and adjusted or re-measured, so that the equipment preparation time is too long to meet the requirements of modern efficient and flexible production. Disclosure of Invention The technical problem to be solved by the invention is to overcome the defects of the prior art and provide welding equipment for cross-assembling the longitudinal and transverse flat steel. The technical scheme for solving the technical problems is that the flat steel accurate positioning device for welding the steel grating comprises a positioning and conveying platform for supporting a conveyor belt support, and a distance adjusting structure for adjusting the flat steel is arranged above the conveyor belt support. Through above-mentioned technical scheme, realize the accurate regulation and control to band steel interval through the roll adjustment structure to effectively solve error big, the inefficiency scheduling problem that exists among the traditional manual positioning mode. The L-shaped supporting frame in the distance adjusting structure provides a stable supporting base for the whole distance adjusting system, and the fixed supporting plate integrates a plurality of uniformly distributed adjusting limiting rails together to form an orderly adjusting platform which can be used for orderly conveying a plurality of flat steels in a clamping mode. The fixed support frame is fixedly welded at one side of the positioning and conveying platform, and a welding platform for welding flat steel is fixedly arranged at the surface of the fixed support frame. Through above-mentioned technical scheme, can be with welding platform steady fixed support on the conveyer belt support through fixed support frame, for flat steel cross welding provides the platform, and fixed support frame and conveyer belt support form triangle-shaped for welding platform supports more stably, and the stress is even. The distance adjusting structure comprises two L-shaped supporting frames which are symmetrically arranged and fixedly connected with two sides of the conveyor belt support, the top positions of the L-shaped supporting frames are fixedly connected with fixed supporting plates, the lower surface positions of the fixed supporting plates are sequentially and fixedly connected with a plurality of evenly distributed adjusting limit rails, and a plurality of distance adjusters which are symmetrically arranged are slidably arranged at the positions of the adjusting limit rails. Through the technical scheme, the distance adjuster can smoothly slide on the adjusting limit rail so as to adapt to the spacing requirements of flat steel with different specifications. When the interval between the flat steels needs to be adjusted, the distance regulator is operated to enable the distance regulator to move to a preset position
