Working principle: the first step: two inner supporting mechanisms 5 are symmetrically and respectively inserted into two ends of a pipeline to be welded, one end of each supporting plate 504 faces into the pipe, the end, away from each supporting plate 504, of each supporting plate is flush with the end face of the pipeline, an external air pump is communicated with an air hole 507, an air cylinder 503 is enabled to stretch, the supporting plates 504 are tightly contacted with the inner wall of the pipeline to fixedly connect the inner supporting mechanisms 5 with the pipeline, the arc rail 104 is started to enable a second rail column 202 to slide along the arc rail 104, a moving ring 402 is driven to deflect from the front side to the lower side (as shown in fig. 1), the pipeline fixedly connected with the inner supporting mechanisms 5 is placed on a bottom plate 101, meanwhile, an elastic telescopic column 404 is pulled to stretch, the moving ring 402 is enabled to be positioned on two sides of the pipeline, a pull rod 510 is pulled out of the second inner groove 508, and a clamping ring groove 513 is clamped into the moving ring 402 through a bayonet 403, then the second rail column 202 slides along the arc rail 104 through the arc rail 104, the moving ring 402 is enabled to deflect from the lower side to the upper side (as shown in fig. 2), the moving ring 402 is enabled to tilt from the upper side, and meanwhile, the pipeline does not need to roll under the gravity action to the fixing mechanism, so that convenience of pipeline fixedly connecting is improved.
And a second step of: the inner support mechanism 5 supports two ends of a pipeline to be welded from the inner side, when the pipeline is welded by the device, the inner support mechanism 5 can support the pipeline from the inside, and when the wall of the pipeline is thin, the inner support effect can be achieved, and the pipeline is better protected.
And a third step of: through the symmetry setting of pipe mechanism 4 on frame mechanism 2 both sides to synchronous pulling elastic telescopic column 404 symmetry extends and makes snap ring groove 513 correspond slip joint and moves ring 402, consequently frame mechanism 2 and interior rotation mechanism 3 are just right the middle part position of pipeline in the in-process of connection and counterpoint voluntarily, and after follow-up pipeline rolls into the rigid coupling mechanism inside, through the centre gripping of starting third electric telescopic column 304 control splint 305 pipeline lateral wall, make splint 305 can stabilize the centre part position of centre gripping at the pipeline, in follow-up operation in-process, the centre gripping can effectually keep the equilibrium of pipeline in the middle part position, be convenient for operate the pipeline.
Fourth step: for the internal support mechanism 5, after the pipeline slides down to the inside of the fixedly connecting mechanism under the action of gravity, the clamping ring groove 513 is automatically separated from the moving ring 402, and the pull rod 510 is automatically pulled back to the inside of the second inner groove 508 under the action of the second spring 512, so that the internal support mechanism 5 can not obstruct the direct bonding of the pipeline in the subsequent pipeline butt joint process; for the pipe feeding mechanism 4, the elastic telescopic columns 404 are required to be stretched at the beginning to enable the moving rings 402 to correspond to two sides of a pipeline, when the pipeline slides into the fixedly connecting mechanism, the corresponding moving rings 402 also lose the pulling limit of the snap ring grooves 513, so that the pipe feeding mechanism 4 can not obstruct the direct fitting of the pipeline under the action of the elastic telescopic columns 404, the cooperation between the device structures is improved, and the device can finish work more smoothly.
Fifth step: after the fixing mechanisms on two sides are used for stably clamping the pipeline, the first sliding rails 102 are started to enable the arc rails 104 to drive the fixing mechanisms to move relatively, meanwhile, the pipeline is attached, and the pipeline is abutted between the middle positions of the first sliding rails 102 through the symmetrical operation of the first sliding rails 102 on two sides, so that the middle positions of the welding rods 112 are automatically adapted, namely, in an initial state, the ends of the welding rods 112 can be automatically aligned with welding seams, and the positioning accuracy of the device is improved.
Sixth step: the end of the welding rod 112 is attached to the position of the pipeline welding seam from the rear side, a certain included angle is formed between the welding rod and the pipeline welding seam, meanwhile, the stretching and shortening of the first electric telescopic column 106 can also control the welding rod 112 to be matched with pipelines with different pipe diameters for angle attachment, and the pipeline size suitability of the device is improved.
Seventh step: after welding, the motor 209 is synchronously started, the second gear 208 and the first gear 206 are driven to rotate through the wheel shaft 207, so that the inner rotation mechanism 3 rotates along the first clamping groove 203 and the second clamping groove 204, and the pipeline is clamped through the gear groove 205, so that the pipeline is driven to rotate, the device automatically rolls the pipeline, the welding rod is kept at the same angle, risks of welding seam deflection, welding rod 112 breakage and the like caused by movement of the welding rod 112 can be avoided, and the welding quality of the device is improved.
Eighth step: the second gears 208 on the left side and the right side are meshed, so that the second gears 208 on the two sides synchronously rotate, the inner rotating mechanism 3 is enabled to rotate stably, and when the inner rotating mechanism 3 drives a pipeline to synchronously rotate, the magnetic blocks 211 on the upper side of the second gears 208 close to the expansion plate 113 can be periodically close to and far away from the corresponding magnetic plates 114 in the rotating process, so that the welding rod 112 can move in a Z shape around a welding seam, the manual welding seam effect of a craftsman is simulated, and the welding firmness is effectively improved.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
