[0054] Please see attached Fig.10 and Fig.11 In this embodiment, an L-shaped fixing frame 24 is fixed to one side of the main fixing plate 27, and a sensor bracket 25 is fixedly installed on the top of the L-shaped fixing frame 24; a first photoelectric sensor 26 is fixed on the sensor bracket 25;

[0055] A second photoelectric sensor 29 is provided below the trunk plate bracket 28 , and the second photoelectric sensor 29 is fixed on the inner side of the main fixing plate 27 .

[0056] As a further explanation of this embodiment, the first photoelectric sensor 26 and the second photoelectric sensor 29 are both electrically connected to the PLC control system; the PLC control system has a PLC controller and a main circuit breaker, and a plurality of AC contactors are connected in series below the main circuit breaker, and the output end of the AC contactor is connected to the solenoid valve for controlling the sliding cylinder 23; the PLC controller is electrically connected to the intermediate relay through a control line, and the output end of the intermediate relay is connected to the coil of the AC contactor through a wire;

[0057] After the first photoelectric sensor 26 or the second photoelectric sensor 29 senses the signal, the PLC controller issues a command to energize the coil of the AC contactor, close its normally open contact, and realize the action of the solenoid valve, thereby realizing the control of the sliding cylinder 23.

[0058] The above control method is an existing technology, and only a brief description is given here, and the existing technical solutions are not described in detail.

[0059] By adopting the above technical solution, when processing the plate nose type lifting lug, firstly, the trunk plate is conveyed to the trunk plate bracket 28 by using the trunk plate feeding assembly 5. When the second photoelectric sensor 29 senses the trunk plate, the cylinder rod of the sliding cylinder 23 extends, so that the main fixed plate 27 drives the trunk plate bracket 28 and the driving frame 210 to slide inward. When the first photoelectric sensor 26 approaches the end face of the material storage rack 311, the sliding cylinder 23 stops moving.

[0060] When the driving frame 210 slides inward, the end of the driving frame 210 presses down the hook rod 37, and the hook rod 37 drives the movable slide 35 to slide downward and compress the spring 38, so that the pressing sheet 36 presses the trunk board against the trunk board bracket 28.

[0061] Then, the cylinder rod of the rib pushing cylinder 312 contracts, so that the pushing rack 310 pushes a rib to slide along the storage rack 311 toward the trunk plate, so that the rib is perpendicular to the trunk plate; with the assistance of the storage rack 311 and the pushing rack 310, the rib is kept vertical, and then the welding mechanism 4 performs double-sided welding on the rib and the trunk plate, thereby realizing the welding forming of the plate nose type lifting ear; this process does not require manual auxiliary welding and improves the processing efficiency of the plate nose type lifting ear.

[0062] After the plate nose type lifting ear is processed, the sliding cylinder 23 drives the main fixed plate 27, the trunk plate bracket 28 and the driving frame 210 to retract to the rear side. After the driving frame 210 is separated from the hook head rod 37, the movable slide 35 slides upward along the fixed slide 34 and resets under the push of the spring 38. At this time, the staff can remove the welded plate nose type lifting ear. During the processing of the plate nose type lifting ear, the staff only needs to take the parts, which effectively reduces the labor intensity.

[0066] One end of the material storage rack 311 close to the trunk bracket 28 is provided with a notch for the ribs to slide out, and the width of the notch is not less than the thickness of the ribs.

[0067] By adopting the above technical solution, when in use, multiple ribs are arranged in the material storage rack 311; the ribs located on the outermost side are fitted in the pushing groove d, and when the cylinder rod of the rib pushing cylinder 312 contracts, the pushing rack 310 will push the outermost ribs to slide out along the groove at the outer end of the material storage rack 311.

[0068] After a rib is pushed out, the cylinder rod of the push cylinder 39 extends to push the ribs in the storage rack 311 by a distance of the thickness of the ribs, always keeping the outermost ribs in the push groove d, thereby realizing the loading of the ribs one by one.

[0069] Please see attached Fig.14 In this embodiment, the welding mechanism 4 includes a hanger 41 fixed to the top cover 17, and a lifting cylinder 42 is fixed on the hanger 41; a hanging seat 43 is fixed to the end of the cylinder rod of the lifting cylinder 42; a transverse cylinder 44 is installed at the bottom of the hanging seat 43, and a side plate 45 is fixed to the end of the cylinder rod of the transverse cylinder 44; a two-way cylinder 46 is fixed to the outside of the side plate 45, and two cylinder rod ends of the two-way cylinder 46 are fixed with an adjusting frame 47, and each adjusting frame 47 is provided with a welding gun 48, and the two welding guns 48 are arranged in a V shape.

At this time, the welding slag on the workbench 1 will fall onto the guide plate 14; then it will be discharged by the guide plate 14, which makes it convenient for the staff to uniformly collect and process the welding slag, thereby ensuring the cleanliness of the workbench.

[0075] Please see attached Figure 3 A support frame 7 for keeping the workbench 1 horizontal is also fixed to one side of the upper end of the frame body 8.

[0076] The support frame 7 is mainly used to support the workbench 1 to ensure that the workbench 1 can be in a relatively stable horizontal state when working.

[0077] See also Figure 7 and Fig. 9 In this embodiment, a support plate 6 is fixed to the side of the frame body 8 away from the synchronous belt 11, and a trunk plate feed assembly 5 is fixed to the support plate 6;

The structure is simple and the operation is convenient, thereby improving the processing efficiency of the plate nose type lifting ear.

[0081] The working principle is as follows: when processing the plate-nose lifting lugs, firstly, a plurality of trunk plates are stacked in the material storage box 54, the cylinder rod of the linear cylinder 55 is extended, and the bottom trunk plate is pushed out by the L-shaped push plate, and pushed to the trunk plate bracket 28, when the second photoelectric sensor 29 senses the trunk plate, the cylinder rod of the sliding cylinder 23 is extended, so that the main fixed plate 27 drives the trunk plate bracket 28 and the driving frame 210 to slide inward, and when the first photoelectric sensor 26 is close to the end face of the material storage rack 311, the sliding cylinder 23 stops moving;

[0082] When the driving frame 210 slides inward, the end of the driving frame 210 presses down the hook rod 37, and the hook rod 37 drives the movable slide 35 to slide downward and compress the spring 38, so that the pressing sheet 36 presses the trunk board against the trunk board bracket 28.

[0084] When the rib plate and the trunk plate are in a vertical posture, the cylinder rod of the lifting cylinder 42 extends out, driving the lifting seat 43 equipped with the transverse cylinder 44 to move downward, so that the two welding guns 48 are located on both sides of the rib plate, and then the two cylinder rods of the two-way cylinder 46 retract inward, so that the two welding guns 48 are located at the gap between the rib plate and the trunk plate, and weld the gap; while welding, the transverse cylinder 44 moves forward to realize the entire welding of the weld by the welding gun 48; this welding method has a consistent welding distance and a stable moving speed, which can ensure the solidity and beauty of the weld; this process does not require manual auxiliary welding and improves the processing efficiency of the plate nose type lifting ear.

[0085] After the plate nose type lifting ear is processed, the sliding cylinder 23 drives the main fixed plate 27, the trunk plate bracket 28 and the driving frame 210 to retract to the rear side. After the driving frame 210 is separated from the hook head rod 37, the movable slide 35 slides upward along the fixed slide 34 and resets under the push of the spring 38.
