Description

Technical Field

[0001] The utility model relates to the technical field of fixing or positioning workpieces, in particular to a horizontal wide-width frame welding device. Background Art

[0002] Welding is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. During the welding process, the workpiece and the solder melt to form a molten area. No matter where it is, welding may bring dangers to the operator, including burns, electric shock, visual impairment, inhalation of toxic gases, excessive ultraviolet radiation, etc., so welding operations are increasingly tending to be automated.

[0003] Rebar welding is a common welding operation, which uses electric welding equipment to connect or cross-connect the steel bars axially. With the development of construction, the requirements for the production of steel bar skeletons are getting higher and higher. Taking the horizontal wide steel bar skeleton as an example, there may be more than dozens of steel bar rings and more than a dozen supporting bars for welding operations.

[0004] In the prior art, when welding a steel bar skeleton, the construction workers generally mark the approximate position of the support bars to be welded after welding the steel bar rings. Then the construction workers spread and align the steel bar rings and weld the support bars to the marked positions. This requires that the steel bar rings must always be aligned during welding, and the support bars cannot have a large offset. Otherwise, after welding, the welding sites of the steel bar skeleton will be irregularly distributed and the force will be different from the expected. At the same time, since a steel bar ring has two welding surfaces, if the operation is done manually, it also involves the need to turn over the semi-finished steel bar skeleton or explore the lower welding site with a welding gun. Based on this, the prior art has the problems of inconvenient positioning of the materials to be welded, low construction efficiency of construction workers in carrying the materials to be welded, inability to guarantee welding accuracy, and difficult welding operations.

[0041] A sensing mechanism is provided in conjunction with the tire frame, the first feeding mechanism, the second feeding mechanism and the conveying mechanism.

[0042] In the present invention, a tire frame is used to spread the first material 1 and the second material 2 and cooperate to complete the welding operation. In the application of the present invention, the first material 1 and the second material 2 are vertical, and the welding point is at the intersection of the first material 1 and the second material 2.

[0049] In the utility model, the separate setting of the left frame 3 and the right frame 4 and the brackets at the bottom of the two ensure the existence of the conveying channel 6 of the first feeding mechanism. The conveying channel 6 has a certain height and width, and the length is consistent with the left frame 3 and the right frame 4, but has space for extension; the two ends of the left frame 3 and the right frame 4 are respectively connected with the steel skeleton 5 to ensure that the positions of the left frame 3 and the right frame 4 are not offset. Of course, in order to realize the placement of first materials 1 of different lengths, in actual applications, the length of the steel skeleton 5 between the left frame 3 and the right frame 4 is adjustable, or a detachable structure is adopted.

[0050] The first feeding mechanism includes an AGV 7 which is arranged at the extension end of the conveying channel 6; a vertical lifting cylinder 8 is arranged in cooperation with the AGV 7, and a support plate 9 is arranged at the output end of the lifting cylinder 8 at the top of the AGV 7, and a plurality of material troughs 10 are arranged on the support plate 9 at preset distances, and the first material 1 is arranged in the material trough 10.

At the same time, a vertical lifting cylinder 8 is arranged in the AGV 7, and a plurality of material troughs 10 for placing the first material 1 are arranged at a preset distance on the support plate 9 at its lifting output end. The first material 1 is loaded into each corresponding material trough 10 and is located at a height slightly higher than the tire frame as required. Then the AGV 7 carries these first materials 1 into the conveying channel 6, and stops at a preset relative position of the tire frame, the lifting cylinder 8 descends, the first material 1 falls into the preset position of the tire frame, the lifting cylinder 8 descends again, the first material 1 is separated from the material trough 10, and the AGV 7 drives out of the conveying channel 6 and waits for the next loading.

[0053] In the utility model, in order to ensure that the first material 1 is stably placed in the material trough 10, a telescopic block 11 is relatively arranged on the trough wall of the material trough 10 and its top and bottom are both slope structures. The telescopic block 11 is generally realized by arranging a compression spring (not shown in the figure) in the trough wall of the material trough 10.

A driving wheel 17 and a driven wheel 18 are provided at the bottom of the tire frame to cooperate with the conveyor belt 16, and the driving wheel 17 is arranged to cooperate with the output end of the motor 19.

[0057] In the utility model, a plurality of material coding trough plates 12 are arranged in groups on the tire frame. Generally speaking, two groups are arranged on the left frame 3 and the right frame 4 respectively, and the material coding troughs 13 thereon match with the material troughs 10 to facilitate the loading of the first material 1.

[0058] In the present invention, after the first material 1 is loaded, it needs to be arranged in the horizontal and vertical directions to align it;

[0059] With the conveying direction as the transverse direction, each group of material trough plates 12 includes two identical material trough plates 12, wherein the bottom of at least one material trough plate 12 penetrates the working surface of the tire frame and cooperates with a conveyor belt 16, a motor 19 drives the driving wheel 17, and the conveyor belt 16 drives the driven wheel 18 to move slightly, while the other material trough plate 12 does not move, that is, the material troughs 13 of the two material trough plates 12 are reduced, and the position of the first material 1 is limited; in principle, at least one material trough plate 12 on the left frame 3 and the right frame 4 is connected to the conveying mechanism;

[0060] In the longitudinal direction, two alignment push plates 14 are arranged on both sides of the tire frame parallel to the material trough plate 12, and one or more cylinders 15 push the alignment push plates 14 from the outside to the inside.

[0062] In the utility model, the second feeding mechanism is generally used to input the second material 2 perpendicular to the first material 1. Here, the stretching cylinder 21 is used to control the movement of the auxiliary rods 20 on both sides. The auxiliary rods 20 are parallel to the conveying channel 6. Therefore, when the movement is controlled by the stretching cylinder 21 at the end of the auxiliary rod 20, the auxiliary rod 20 moves back and forth along the direction of the conveying channel 6. Under the action of the gear rack assembly 22, the opening and closing rod 23 that is arranged in conjunction with it is opened.

In this case, a structure in which the opening and closing rod 23 and its roller 24 can be lifted is provided. To be precise, the lifting cylinder 26 is controlled to act on the top plate of the opening and closing rod 23.
