Description

Profile steel double-machine-position cooperative overturning device with concentric adjustment and elastic compensation functions Technical Field The invention relates to the field of steel structure production, in particular to a section steel double-machine-position cooperative overturning device with concentric adjustment and elastic compensation functions. Background In a steel structure processing and manufacturing production line, long-size section steel (such as I-steel, H-steel, steel beams and the like) always needs to be overturned in the welding, assembling and detecting processes, particularly, a double-machine-position overturning mode is generally adopted for section steel members with long length and large weight, namely overturning mechanisms are respectively arranged at two ends of the section steel members, and then the section steel is integrally overturned through synchronous driving under system control. However, in the prior art, the double machine positions of the section steel turnover device are usually fixed, and the section steel to be turned is generally fixed by adopting a rigid clamping mechanism, for example, a driving device of the section steel turnover mechanism for welding is disclosed in CN115625470a, the frames on two sides of the driving device are both fixed, and two pairs of clamping rods for clamping the section steel are directly connected with a control device for driving the clamping rods to stretch. This fixed structure is affected by the following factors in the actual use process: One is that the driving mechanism at two ends has response difference and fine speed deviation. And secondly, the section steel has certain deflection and manufacturing dimensional deviation. Thirdly, the coaxiality deviation of the double machine positions can be caused by installation errors, foundation deviations and the like of the device. And fourthly, the structure is elastically deformed under the heavy load state. The above factors easily cause the asynchronous phenomenon at the two ends of the section steel in the double-machine-position cooperative overturning process, so that the section steel member is subjected to additional torsional load or bending stress. At present, some devices improve the synchronism by improving the control precision or adopting a mechanical coupling structure, but the mode still has difficulty in completely eliminating the influence caused by structural errors and load fluctuation, and the system has higher cost, complex structure and great maintenance difficulty. Disclosure of Invention The invention aims to provide a section steel double-machine-position cooperative overturning device with concentric adjustment and elastic compensation functions, wherein overturning clamping seats at two sides of the section steel double-machine-position cooperative overturning device can realize an automatic alignment function before section steel is input, and a buffer module can absorb synchronous errors and impact loads between mechanisms at two sides in the section steel clamping overturning process, so that risks of deformation and the like of section steel components can be greatly reduced. The aim of the invention is realized by the following technical scheme: The section steel double-machine-position cooperative overturning device with the concentric adjusting and elastic compensating functions comprises a base station, an overturning clamping seat and a clamping jaw mechanism, wherein an overturning base capable of being adjusted in a moving mode is arranged on the base station, an overturning gear, an upper limiting wheel set and a lower limiting wheel set are arranged on the overturning base, an overturning toothed ring is arranged on the overturning clamping seat and meshed with the overturning gear, overturning limiting protrusions are arranged on two sides of the overturning clamping seat and are arranged between the upper limiting wheel set and the lower limiting wheel set on the corresponding side on the overturning base, the clamping jaw mechanism is arranged in the corresponding overturning clamping seat and comprises two clamping jaws and an opening and closing screw rod capable of being rotated, clamping jaw nuts are sleeved at the rear ends of the clamping jaws, a buffer module is arranged on the clamping jaw of any side of the clamping jaw mechanism, the upper end of the buffer module is connected with the corresponding clamping jaw nuts, and an elastic element is arranged in the buffer module. The buffering module comprises an upper connecting plate, an elastic element and a lower connecting plate which are sequentially connected, wherein the upper connecting plate is fixedly connected with a corresponding clamping jaw nut, the lower connecting plate is fixedly connected with a buffering seat arranged on a corresponding clamping jaw, and through holes for a stretching screw to pass through are formed in the lower connecting plate and the
