When the fourth servo motor 310 is started, since the output shafts of the fourth servo motor 310 are limited by the upright post 220 and cannot rotate, the housings of the two fourth servo motors 310 respectively drive the first rack 320 and the second rack 340 to rotate around the first gear 330, so that the first rack 320 and the second rack 340 are far away from each other, and when the first rack 320 and the second rack 340 are far away from each other until the two clamping blocks 360 are in contact with the mounting shell 350, a first preset position of the first rack 320 and the second rack 340 is reached, and the mounting shell 350 limits the movement of the clamping blocks 360, so that the movement of the first rack 320 and the second rack 340 is limited. The first servo motor 420 is mounted on the mounting case 350.
In this embodiment, by setting the first rack 320, the second rack 340, the first gear 330, the two fourth servomotors 310, the two jaws 210 and the two upright posts 220, before driving the positioning connection board 800 to rotate around its own vertical axis, the two fourth servomotors 310 are driven to rotate, and the rotation directions of the two fourth servomotors 310 are opposite, so that the first rack 320 and the second rack 340 are far away from each other, and further the two jaws 210 slide along the wing plate 110, and when the rotation angle of the fourth servomotors 310 is 90 ° - α, the included angle between the positioning connection board 800 and the wing plate 110 is α. Because the positioning connection plate 800 is mounted on the mounting shell 350, the rotation of the fourth servo motor 310 will also drive the positioning connection plate 800 to synchronously rotate by 90 ° - α, after the rotation angle of the fourth servo motor 310 is 90 ° - α, the first preset positions of the first rack 320 and the second rack 340 are reached, the rotation of the fourth servo motor 310 is stopped, and then if the positioning connection plate 800 needs to continue to rotate around its own vertical axis, the first servo motor 420 needs to be started. On the one hand, the first rack 320, the second rack 340 and the upright 220 after rotation are no longer vertical, so that when the positioning connection plate 800 is welded, the welding process is not affected due to the limitation of the upright 220, and the welding is convenient to carry out. On the other hand, the rotation of the fourth servo motor 310 can also synchronously drive the positioning connection plate 800 to rotate around the vertical axis of the positioning connection plate, so that the rotation amount of the positioning connection plate 800 driven by the fourth servo motor 310 is reduced. When the first rack 320 and the second rack 340 are required to be close to each other, the first and second racks 320 and 340 are driven to rotate, and the rotation directions of the two fourth servomotors 310 are opposite, which means that, at this time, the rotation directions of the two fourth servomotors 310 are opposite to the rotation directions of the two fourth servomotors 310 when the first and second racks 320 and 340 are driven to be away from each other, so that when the two fourth servomotors 310 rotate, the output shafts of the fourth servomotors 310 are limited by the upright post 220 and cannot rotate, the shells of the two fourth servomotors 310 drive the first and second racks 320 and 340 to rotate around the first gear 330, so that the first and second racks 320 and 340 are close to each other, and at this time, 360 on the first and second racks 320 and 340 are separated from each other, so that the first and second racks 320 and 340 realize return.
By combining the above embodiments, the specific working principle and working process are as follows:
before use, two claws 210 are slidably mounted on marked positions on the two wing plates 110, and the universal positioning and connecting device based on BIM is slidably connected with the main beam 100 through the claws 210.
Then, the positioning connection plate 800 is sleeved on the inner side of the fixing sleeve 700, and then an external power supply is connected to energize the electromagnet 710, so that the fixing sleeve 700 and the positioning connection plate 800 are locked by the electromagnet 710. And then, the second servo motor 510 is driven to enable the positioning connection plate 800 to be in contact with and vertical to the upper surface of the web plate 120, so that the installation of the positioning connection plate 800 is completed.
Before use, a BIM positioning sheet is stuck on the positioning connection plate 800, and a positioning instrument with a proper angle is adopted for welding the positioning connection plate 800 to determine the welding position and the inclination angle of the positioning connection plate 800. The BIM locating plate carries position and angle information, and then the BIM locating plate is adjusted according to the position and angle information carried on the BIM locating plate.
If the angle information carried by the BIM positioning sheet needs to drive the positioning connection board 800 to rotate around the vertical axis of the positioning connection board, before the first servo motor 420 is driven to rotate, for convenience of welding, the fourth servo motors 310 are driven to rotate first, and the rotation directions of the two fourth servo motors 310 are opposite, because the output shafts of the fourth servo motors 310 are limited by the upright post 220 and cannot rotate, the shells of the two fourth servo motors 310 respectively drive the first rack 320 and the second rack 340 to rotate, so that the first rack 320 and the second rack 340 are mutually far away from each other to the first preset position, at this time, the fourth servo motors 310 rotate by 90 ° - α, and because the positioning connection board 800 is mounted on the mounting shell 350 through the rotating frame 410, the fourth servo motors 310 rotate to drive the positioning connection board 800 to synchronously rotate by 90 ° - α, when the carrying position and the angle information of the BIM positioning sheet are smaller than 90 ° - α, the rotation angle of the positioning connection board 800 can be determined only by driving the angle parameters of the fourth servo motors 310 to rotate, and after the rotation to the specified angle is stopped. As shown in fig. 9, when the fourth servo motor 310 is rotated by 90 ° - α, the angle between the positioning connection plate 800 and the wing plate 110 is α.
After the fourth servo motor 310 stops rotating, if the positioning connection plate 800 needs to continue rotating around its own vertical axis, the first servo motor 420 needs to be started, and the first servo motor 420 drives the rotating frame 410 to rotate, so as to drive the positioning connection plate 800 to rotate around its own vertical axis, as shown in fig. 10, at this time, the positioning connection plate 800 continues rotating β.
On this basis, if the position of the vertical center line of the positioning connection plate 800 needs to be adjusted, the second servo motor 510 is driven to rotate, the second servo motor 510 drives the second gear 530 to rotate, and because the third rack 413 inside the rotating frame 410 cannot move, the second gear 530 moves in the first slot 411 along the direction of the first slot 411, that is, along the first direction, so as to drive the two ends of the positioning connection plate 800 to slide in the first slot 411 and the second slot 412 along the first direction respectively, as shown in fig. 11 and 12, which indicates that the distance that the two ends of the positioning connection plate 800 slide in the first slot 411 and the second slot 412 along the first direction respectively is c. The angle between the positioning web 800 and the web 120 is 90.
Then, if the included angle between the positioning connection plate 800 and the web 120 is to be changed, the third servo motor 610 may be driven to rotate, so that the positioning connection plate 800 rotates, as shown in fig. 13 and 14, and at this time, the included angle between the positioning connection plate 800 and the web 120 is δ.
After the angle and position information are adjusted, the final position of the positioning connection plate 800 is determined, the positioning connection plate 800 and the web 120 are welded in a welding mode, then the electromagnet 710 is powered off, the fixing sleeve 700 is taken out of the positioning connection plate 800, then the claw 210 is moved to separate from the wing plate 110, and then the positioning connection plate 800 and the oblique beam are fixed.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
