S2: intermittent welding process: however, with the upgrading of steel building structural strength, usually the pipe fitting of both sides is not required to be laminated together completely and just can reach the connection needs, just carry out the laminating of several spot connections in pipe fitting department and just can realize the support demand of building, but the welding process of conventional art is when realizing the spot connection welding process, it can only be realized through the continuous laser welding head of control opening or closing, so, the operation complicacy has just been caused and the laser welding head damage condition has been increased, therefore, the spacing subassembly 5 has been designed in this case, make when need carry out equidistant spot welding between the pipe fitting, the user can place the laser baffle 507 of corresponding proportion in the inside of frame 504 earlier, then coincide with above-mentioned process, start laser welding head 9 and driving motor 301 promptly, and driving motor 301 is when using, because need drive pipe fitting rotation through fluted roller 306 and gear 303, make simultaneously gear 303 alright drive frame 504 through rack 502 and open or close, frame 504 is in the removal process, laser baffle 507 and through-hole portion will intermittent type appear in the below of welding head 9 and realize shielding, the equidistant laser welding head shelter from the realization, and can only be realized the laser welding head damage has been realized through the equidistant control of laser welding head that the equidistant joint has just been realized effectively avoiding the equidistant problem of realizing that the laser welding joint is difficult to open or has just been difficult to realize so when using.
Meanwhile, due to the fact that the rack 502 is added to serve as transmission connection in the conventional technology, the transmission structure in the conventional technology is changed slightly, and due to the fact that shielding of laser beams is controlled in a mode of matching the rack 502 with the gear 302, a certain linkage process is achieved between rotation of the pipe fitting and shielding of the laser beams, and the problem that welding matching errors are caused if the linkage performance is poor due to the fact that a simple laser beam shielding process is adopted is effectively solved.
S3: the rotation transmission process comprises the following steps: compared with the prior art, because the sliding platforms on two sides need to perform lateral position change, most of the driving mechanism adopts a mode of respectively designing two groups of power sources on the sliding platforms on two sides to drive the pipe fittings on two sides to rotate synchronously, however, more cost and synchronism requirements are required for the two groups of power sources to affect specific equipment use, therefore, the driving assembly 3 is designed, when the driving motor 301 is started, the output shaft of the driving motor 301 drives the toothed roller 306 to rotate first, and then the toothed roller 306 drives the gear 303 to rotate further, so that even if the gear 303 moves to any lateral position along with the sliding platform 307, the meshing state between the toothed roller 306 and the gear 303 is still maintained, and further the gear 303 with the position change on two sides is driven by a single power source to rotate, so that the problems that the mode of respectively designing two groups of power sources on two sides needs more cost and synchronism requirements to affect specific equipment use are effectively avoided.
S4: the technical advantages are that:
In the prior art, along with the upgrading of the structural strength of a steel building, the joint requirement of the building can be met usually without completely jointing the pipe fittings on two sides together, and the joint requirement of the building can be met only by jointing a plurality of points at the pipe fittings, but most of the welding process of the prior art can only be realized by controlling the continuous laser welding heads to be opened or closed in the process of realizing the point joint welding process, so that the operation is complicated and the damage condition of the laser welding heads is increased, therefore, the limiting assembly 5 is designed, when equidistant spot welding between the pipe fittings is required, a user can firstly place the corresponding proportion of the laser baffle 507 in the frame 504, and then the process is consistent with the process, namely, the laser welding heads 9 and the driving motor 301 are started, and when the driving motor 301 is used, the pipe fittings are driven to rotate through the transmission of the toothed roller 306 and the gear 303, so that the gear 303 can drive the frame 504 to move forwards through the rack 502, the shielding part and the through hole part of the laser baffle 507 intermittently appear below the laser welding heads 9 in the moving process, so that the shielding of the laser welding heads is realized, the problem of the laser welding heads can only be effectively prevented from being damaged by the equidistant welding heads being opened or closed, and the problem of the laser welding is effectively avoided;
Meanwhile, the design of the scheme only adds the rack 502 as transmission connection in the traditional technology, so that the transmission structure in the traditional technology is changed less, and the shielding of the laser beam is controlled in a mode of matching the rack 502 with the gear 302, so that a certain linkage process is provided between the rotation of the pipe fitting and the shielding of the laser beam, and the problem of welding matching errors caused by poor linkage property if a simple laser beam shielding process is adopted is effectively avoided;
In the prior art, because the sliding platforms at two sides need to perform lateral position change, most of the driving mechanism adopts a mode of respectively designing two groups of power sources at the sliding platforms at two sides to drive the pipe fittings at two sides to rotate synchronously, however, more cost and synchronism requirements are required for the two groups of power sources to affect the use of specific equipment, therefore, the driving assembly 3 is designed, when the driving motor 301 is started, the output shaft of the driving motor 301 drives the toothed roller 306 to rotate first, and then the toothed roller 306 drives the gear 303 to rotate further, so that even if the gear 303 moves to any lateral position along with the sliding platform 307, the meshing state between the toothed roller 306 and the gear 303 is still maintained, and further the gear 303 with the position change at two sides is driven by a single power source to rotate, therefore, the problem that the use of specific equipment is affected by more cost and synchronism requirements for the mode of respectively designing two groups of power sources at two sides of the sliding platform is effectively avoided.
While the invention has been shown and described with reference to a preferred embodiment, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the scope of the invention.
