[0060] Since the volume of the square pipe column will change after the corbel is installed, the structure of the first movable turning frame 102 cannot be used for fixed turning, and the structure of the third movable turning frame 302 must be used, that is, an opening 603 is set on the second rotating frame 602 to facilitate the removal of the square pipe column, and the transfer of the square pipe column between the transition roller conveyor line 5 and the corbel assembly mechanism 3, and the transfer of the square pipe column between the corbel assembly mechanism 3 and the full penetration welding mechanism 4 are all transferred by crane hoisting.

Then, the first driving motor 515 is started, and the first rotating frame 502 is driven to rotate and flip through the first driving gear and the first transmission arc rack 516 to cooperate with the chamfering robot to perform chamfering operations. After the chamfering is completed, the movable cylinder 512 drives the moving rod 510 to reset, and the square pipe column is conveyed into the tongue plate assembly mechanism 2, and is moved by the two second movable flip frames 208 of the tongue plate assembly mechanism 2. Since the second movable flip frame 208 can move on the tongue plate assembly seat 207, as long as one second movable flip frame 208 is in a loose state, the other second movable flip frame 208 is in a clamped state, and then the square tube column can be pulled to move on the tongue plate assembly seat 207. In this embodiment, the first fixed roller 504, the first movable roller 505, the second fixed roller 506, and the second movable roller 507 are all equipped with independent reduction motors 508, which can greatly improve the transfer capacity. After the square tube column is transferred to the position, the tongue plate is installed on the magnetic positioning plate 203. After the lifting cylinder 205 drives the support plate 204 to move up to the position, the moving cylinder 206 drives the moving seat 201 to move toward the square tube column so that the tongue plate adsorbed on the magnetic positioning plate 203 is inserted into the square tube column. Then, the tongue plate welding robot performs spot welding to achieve a reliable connection between the tongue plate and the square tube column.After the tongue plate is assembled, the square tube column is transferred to the transition roller conveyor line 5 through the two second movable turning frames 208, and then the square tube column on the transition roller conveyor line 5 is transferred to the opening 603 of the third movable turning frame 302 by the driving. At this time, the pressing cylinder 606 drives the pressing plate 605 to move down to press the square tube column. Then, the electric cylinder drives the third movable turning frame 302 to move on the corbel assembly seat 301 to drive the square tube column to move until one end of the square tube column abuts against the limit stopper at the front end. Then, the corbel positioning device 304 starts to work, and the second motor 319 drives the support 306 to move to the specified position in the left and right directions. The first motor The first motor 314 drives the support arm 307 to move upward, and then the third motor 322 drives the positioning seat 308 to move backward to the top of the square tube column. Then, the first motor 314 drives the support arm 307 to move downward until the inner side surface of the first positioning arm 309 presses against the inclined surface on the front side of the square tube column, and the inner side surface of the second positioning arm 310 presses against the inclined surface on the rear side of the square tube column. At this time, the bracket can be installed. Since the first positioning block 312 protrudes from the side end surface of the first positioning arm 309, the second positioning block 313 protrudes from the side end surface of the second positioning arm 310, and the positions of the first positioning block 312 and the second positioning block 313 are based on the installation of the bracket. The position is designed, when the corbel is installed on the inclined surface on the front side of the square tube column, the inner side of the corbel is pressed on the square tube column, one side of the corbel in the left-right direction presses against the side end surface of the first positioning arm 309, and one end of the corbel in the front-back direction presses against the first positioning block 312; when the corbel is installed on the inclined surface on the rear side of the square tube column, the inner side of the corbel is pressed on the square tube column, one side of the corbel in the left-right direction presses against the side end surface of the second positioning arm 310, and one end of the corbel in the front-back direction presses against the second positioning block 313; after the corbel is positioned, spot welding is performed by the corbel welding robot 303 to fix the corbel, and then the second motor 319 drives The movable support 306 moves in the left and right direction to the next position to install the bracket. After all the brackets are installed, the flange is installed at the end of the square tube column. Then, the pressing plate 605 of the third movable turning frame 302 moves upward and is released. The square tube column is hoisted into the opening 603 of the fourth movable turning frame 402 by the crane. Then, the pressing cylinder 606 drives the pressing plate 605 to move downward to press the square tube column. The second driving motor 607 is started, and the second rotating frame 602 is driven to turn over through the second driving gear and the second transmission arc rack 608. While turning over, the penetration welding robot 403 performs full welding. After the full welding is completed, the processing and production of the entire square tube column is completed. ;

[0062] This embodiment also discloses a square tube column production process using the square tube column production line as described above, comprising the following steps:

[0063] a. Chamfer both ends of the pipe column;

[0064] b. Insert tongue plates at both ends of the square tube column and fix them by spot welding;

[0065] c. Spot weld the bracket and flange on the square tube column;

[0066] d. Fully weld the other pipe column.

[0067] The above-mentioned square tube column production line and production process realize the fully automated production of square tube columns, completely subverting the original segmented and discontinuous production mode of square tube columns, greatly improving production efficiency and product quality, saving a lot of manpower, material resources, energy and space, and greatly reducing the unsafe factors between processes.

[0068] The above embodiments are only to illustrate the basic principles and characteristics of the present invention. The present invention is not limited by the above embodiments. Without departing from the spirit and scope of the present invention, the present invention may be subjected to various changes and modifications, which are within the scope of the present invention to be protected. The scope of protection of the present invention is defined by the attached claims.
