[0016] The operating method of the prefabricated beam welding device includes the following steps:

[0017] S1: The electric screw on the workbench can drive the fixed frame to move on the workbench. At this time, the fixed frame will move the welding structure and positioning module on it horizontally. The user will place the support steel plate to be welded under the positioning plate. Then the first electric cylinder will drive the moving platform and the positioning plate to move downward, so that the inclined surface of the positioning plate presses against the top of the support steel plate. The positioning plate will be forced to move open, and the clamping spring will push the positioning plate to position the support steel plate through the reset effect. The moving platform will simultaneously fix the support steel plate. The servo motor will drive the loading block to move along the limit rod through the transmission screw.

[0018] S2: The loading block will drive the force-bearing rod in the vertical slot to move along the through guide groove on the guide plate. When the force-bearing rod moves obliquely upward along the guide groove on the guide plate, the force-bearing rod drives the deflection block on the deflection plate to press against the secondary limiting plate in the locked state. The deflection plate will drive the welding gun head to rotate clockwise to the maximum angle through the force-bearing rod. The deflection limiting column will move the top of the arc groove on the loading block, and the muzzle of the welding gun head will face the oblique welding position of the steel plate for oblique welding. After the deflection block passes through the locking automatic control mechanism, the deflection block will push the unlocking head to move, and the unlocking head pushes the one-way locking head to move through the guide block, so that the top end of the one-way locking head can enter the guide block. At the same time, the guide block drives the rotating arm to rotate through the thrust rod, and the pressure head on the top of the rotating arm will contact the inner wall of the secondary limiting plate. At this time, the one-way locking head no longer locks the secondary limiting plate.

[0019] S3: When the force-bearing rod drives the deflection plate to move toward the reset protrusion on the top of the loading block, the resistance block on the deflection plate will be subjected to the reverse pressure of the reset protrusion. At this time, the deflection plate will rotate and reset under the reverse pressure of the reset protrusion. At this time, the welding gun head will be vertically aligned to weld the steel plate and the top of the prefabricated beam box rib. Since the secondary restriction plate is no longer locked, the reset and rotating deflection plate can push the secondary restriction plate to move backward first through the deflection block. At this time, the secondary restriction plate will push the rotating arm to reset again. At this time, the unlocking head will be extended again, and the one-way locking head can enter the opening of the guide block again. If the deflection plate is completely reset horizontally, the pressure spring can push the secondary restriction plate to reset. At this time, the one-way locking head will re-enter the locking hole on the secondary restriction plate under the pressure of the reset spring;

[0020] S4: When the stress rod moves obliquely downward along the guide groove on the guide plate, the deflection plate will drive the welding gun head to rotate counterclockwise through the stress rod, so that the muzzle of the welding gun head will face the oblique welding position on the other side of the steel plate, and the locking automatic control mechanism will operate according to the above steps, thereby realizing welding of the welding gun head along the fitting position of the steel plate.

[0021] Compared with the prior art, the present invention has the following advantages: the prefabricated beam welding device and its use method are provided with a welding gun head that can automatically move along the contact area between the supporting steel plate and the prefabricated beam box rib. During the welding process, workers do not need to hold the welding gun equipment to operate, thereby reducing the labor intensity of workers. In addition, the steel plates to be welded can be quickly positioned during use of the device. The specific contents are as follows:

[0022] The top end of the support leg is fixedly provided with a toothed plate, and the toothed plate is fixed with a toothed plate at the bottom end thereof, and the toothed plate is fixed with a toothed plate at the bottom end thereof, and the toothed plate is fixed with a toothed plate at the bottom end thereof, and the toothed plate is fixed with a toothed plate at the bottom end thereof,

[0023] 2. The automatic positioning module includes a moving platform fixedly set on the moving end of the first electric cylinder, and a symmetrically distributed positioning plate is slidably embedded in the lower part of the moving platform. The lower part of the positioning plate is provided with an inclined surface, and a cross guide rod is slidingly penetrated on the top of the positioning plate. Symmetrically distributed clamping springs are provided on both sides of the cross guide rod. The clamping springs are fixedly connected between the inner wall of the moving platform and the top side wall of the positioning plate. A symmetrically distributed first electric cylinder is fixedly installed on the top of the fixed frame. When the first electric cylinder pushes the moving frame to move downward and press against the top of the steel plate, the inclined surface at the bottom of the positioning plate will be forced to move. At this time, the positioning plate will compress the clamping spring, and the positioning plate will position the top of the steel plate under the action of reverse pressure.

[0044] The operating method of the prefabricated beam welding device includes the following steps:

[0045] S1: The electric screw 3 on the workbench 2 can drive the fixing frame 1 to move on the workbench 2. At this time, the fixing frame 1 moves the welding structure and positioning module thereon horizontally. The user places the supporting steel plate to be welded under the positioning plate 6. Then the first electric cylinder 4 drives the moving platform 5 and the positioning plate 6 to move downward, so that the inclined surface of the positioning plate 6 presses against the top of the supporting steel plate. The positioning plate 6 will be forced to move open, and the clamping spring 8 will push the positioning plate 6 to position the supporting steel plate through the reset action.

[0047] When the deflection plate 17 is completely reset to the horizontal position, the pressure spring 28 can push the secondary limiting plate 25 to reset. At this time, the one-way locking head 2605 will re-enter the locking hole on the secondary limiting plate 25 under the pressure of the reset spring 2604;

[0048] S4: When the force-bearing rod 16 moves obliquely downward along the guide groove on the guide plate 11, the deflection plate 17 will drive the welding gun head 18 to rotate counterclockwise through the force-bearing rod 16, so that the muzzle of the welding gun head 18 will face the oblique welding position on the other side of the steel plate, and the locking automatic control mechanism 26 will operate according to the above steps, thereby realizing the welding of the welding gun head 18 along the fitting position of the steel plate.
