Technical Field

[0001] The present application relates to the technical field of welding devices, and in particular to a copper-clad steel welding device. Background Art

[0002] Copper-clad steel is a cost-effective grounding material that combines the advantages of copper's high corrosion resistance and high conductivity with steel's high strength and low price. Copper-clad steel has been widely used in power system grounding projects. In the production of copper-clad steel, two sections of copper-clad steel bars need to be welded. The copper-clad steel bar includes a copper layer and a steel base layer, and the copper layer is covered on the surface of the steel base layer.

[0003] The copper-clad steel welding device in the related technology includes a transport component and a welding mechanism. The staff or the robot places the two sections of the bar material on the transport component respectively. The transport component makes the two sections of the bar material approach each other until the ends of the two sections of the bar material abut against each other. Then the welding mechanism welds the ends of the two sections of the bar material. Finally, the transport component unloads and transports the welded bar material.

[0004] However, in the related art, the welding mechanism is located on one side of the bar for spot welding, which is suitable for bars with smaller diameters. When the diameter of the bar is larger, it is easy to cause uneven welding of the bar, affecting the welding stability of the bar. In addition, the position of the welding mechanism is relatively fixed, which is difficult to adapt to the welding of bars with different diameters. Summary of the invention

[0005] In order to improve the uneven welding of bars and facilitate welding of bars with different diameters, the present application provides a copper-clad steel welding device.

[0008] frame;

[0009] A transport component, the transport component is arranged on the frame, and the transport component is used to transport bar materials;

[0010] A welding mechanism, which includes a containing ring seat, a rotating assembly, a telescopic assembly, a welding gun and an end clamping assembly; the containing ring seat is connected to the frame, and the ends of two sections of rod stock are located in the containing ring seat and abut against each other; the end clamping assembly is connected to the containing ring seat, and the end clamping assembly clamps the end of the rod stock; the rotating assembly includes a guide ring rail, a supporting base block and a rotating drive source, the guide ring rail is connected to the containing ring seat, and the supporting base block is slidably connected to the guide ring rail; the telescopic assembly is connected to the supporting base block, and the welding gun is connected to the telescopic assembly, and the telescopic assembly drives the welding gun to move in a direction close to or away from the rod stock; the rotating drive source drives the supporting base block to slide along the inner wall of the guide ring rail, so that the welding gun welds the end of the rod stock in a circumferential direction.

[0011] By adopting the above technical solution, the transport assembly loads and transports the bar material, and after the ends of the two sections of the bar material abut against each other, the end clamping assembly clamps the end of the bar material, thereby improving the stability of the end of the bar material during welding and reducing the risk of deformation during welding. The telescopic assembly can drive the welding gun to approach or move away from the bar material, thereby being able to adapt to the welding of bars of different diameters and improving applicability. The rotating drive source drives the welding gun to weld the bar material in the circumferential direction along the guide ring rail, thereby improving the uniformity of welding and the stability after welding.

[0012] Optionally, the rotating assembly further includes:

[0013] A supporting ring rail, the supporting ring rail is connected to the containing ring seat;

[0014] A rotating gear ring, wherein the rotating gear ring is rotatably connected to the supporting ring rail, and the rotating gear ring is connected to the supporting base block;

[0015] A driving gear, the rotation driving source is connected to the accommodating ring seat, the rotating ring gear is connected to the output shaft of the rotation driving source, and the driving gear is meshed with the rotating ring gear.

[0016] By adopting the above technical solution, the rotating driving source drives the rotating ring gear to rotate through the driving gear, and the rotating ring gear drives the supporting base block to move, so that the supporting base block slides along the guide ring rail, thereby realizing the movement of the welding gun in the circumferential direction, improving the uniformity and stability of welding, improving the welding quality, and enhancing the mechanical strength of the welding part.

[0017] Optionally, the telescopic component includes:

[0018] a telescopic driving source, the telescopic driving source being connected to the supporting base block;

[0019] A support sliding seat is slidably connected to the support base block, and the telescopic driving source drives the support sliding seat to slide, so that the welding gun moves in a direction close to or away from the bar material.

[0020] By adopting the above technical solution, the support sliding seat is slidably connected to the support base block, and the telescopic driving source drives the support sliding seat to slide, so that the welding gun can accurately move toward or away from the rod, thereby enabling the welding gun to weld rods of different diameters.

[0021] Optionally, the supporting sliding seat is connected to two distance detection members, which are respectively located on both sides of the welding gun, and the two distance detection members correspond to two sections of bar stock one by one, respectively, and the distance detection members are used to detect the distance between themselves and the bar stock.

[0022] By adopting the above technical solution, the distance detection piece can detect the distance between itself and the bar material, so as to obtain the diameter information of the bar material, so as to adjust the moving distance of the welding gun close to the bar material, improve the accuracy of the welding gun aligning with the bar material, and thus ensure the stability and consistency of the welding quality. Through precise distance control, the collision between the welding gun and the bar material can also be reduced, and the service life of the equipment can be extended. In addition, the two distance detection pieces correspond to the two sections of bar material one by one, and the two distance detection pieces can respectively detect whether the diameters of the two sections of bar material are consistent, reducing the problem of mismatch in the diameters of the two sections of bar material due to incorrect loading.

[0023] Optionally, a grinding assembly is provided on the supporting base block, and the grinding assembly includes:

[0024] A driving source connected to the supporting base block;

[0026] The grinder is arranged on the bearing slide, and the driving source drives the bearing slide to slide, so that the grinder approaches or moves away from the bar material, and the grinder grinds the end of the bar material.

[0027] By adopting the above technical solution, before welding, the grinder removes the copper layer on the surface of the bar, which is conducive to improving the welding performance. After welding, the grinder can grind the welding part to remove welding slag and burrs, and improve the flatness and aesthetics of the welding surface. The driving source controls the feed of the grinder to ensure precise control of the grinding process and reduce excessive grinding to damage the bar.

[0028] Optionally, the grinder includes a grinding drive source and a grinding head, the bearing slide is connected to a pressure sensor, the grinding drive source is connected to the pressure sensor, the grinding head is connected to the output shaft of the grinding drive source, and the pressure sensor is used to detect the clamping force between the grinding head and the rod.

[0029] By adopting the above technical solution, the grinding drive source is connected to the pressure sensor to ensure that the clamping force between the grinding head and the bar is effectively controlled, which not only improves the accuracy of the grinding process, but also reduces the problem of uneven grinding or damage to the bar caused by excessive or insufficient pressure. The pressure sensor monitors the contact pressure between the grinding head and the bar in real time, ensures the grinding quality of the welding point, and improves the reliability of the final product. In addition, after the welding is completed, the driving source is pushed to push the grinder close to the bar, so that the grinding head applies a clamping force to the bar, and the pressure sensor detects whether the clamping force reaches the predetermined detection value, thereby judging whether the bar welding is up to standard. If the welding is not up to standard, it is necessary to perform repair welding. In the related art, for the detection of the welding strength of the bar, generally after the bar welding is completed, the bar is unloaded and transported, and then the bar is transported and clamped to a specific detection mechanism for detection, and the transportation and clamping will lead to additional processes, which takes a certain amount of time and easily reduces the processing efficiency. However, the present application can detect immediately after the bar welding is completed, saving the time of transportation and clamping, and improving the processing efficiency.

[0031] By adopting the above technical solution, after the bar is welded, it is necessary to wait until the bar is cooled and shaped before grinding. The cooling air duct can quickly blow air to the end of the bar after welding is completed, which accelerates the cooling process of the bar, reduces waiting time, is beneficial to subsequent grinding operations, and improves processing efficiency.

[0032] Optionally, a collecting assembly is provided on the frame, and the collecting assembly includes a collecting hopper and an aggregate filter box. The collecting hopper is connected to the containing ring seat, and the collecting hopper is communicated with the aggregate filter box. The aggregate filter box is externally connected to a negative pressure exhaust source, and the cooling air duct blows the grinding debris toward the collecting hopper.

[0033] By adopting the above technical solution, the cooling air duct blows the debris generated by grinding to the collection hopper, reducing the splashing of debris. At the same time, the aggregate filter box further improves the collection efficiency of debris through an external negative pressure exhaust source, ensuring a clean working environment.

[0034] Optionally, the frame is provided with an abutment mechanism, the abutment mechanism is located between the transport assembly and the welding mechanism, and two groups of abutment mechanisms are provided, and the two groups of abutment mechanisms are respectively located on both sides of the welding mechanism;

[0035] The abutment mechanism includes a movable slide, a clamping assembly and a point position detection assembly; the movable slide is connected to the frame, the clamping assembly is connected to the movable slide, and the movable slide drives the clamping assembly to move toward the direction close to the accommodating ring seat; the point position detection assembly is connected to the frame, and the point position detection assembly detects the position of the bar; when the point position detection assembly detects that the bar has reached a predetermined position, the clamping assembly clamps the bar, and the movable slide makes the ends of two sections of the bar abut against each other.

[0036] By adopting the above technical solution, the two sets of abutment mechanisms are located on both sides of the welding mechanism. The abutment mechanisms can accurately control the docking process of the two sections of the bar material, ensure the accurate positioning of the bar material before welding, and improve the accuracy and reliability of the docking. The point detection component monitors the position of the bar material in real time to ensure that the clamping component can clamp the bar material at the right time, reducing the problem of poor welding caused by position deviation. The mobile slide drives the clamping component to move accurately, so that the ends of the two sections of the bar material are tightly abutted, which enhances the stability and consistency of welding.

[0037] Optionally, the clamping assembly includes a clamping drive source, a tightening telescopic rod and a spring sheet, the clamping drive source is connected to the movable slide, the tightening telescopic rod is connected to the clamping drive source, the spring sheet is connected to the tightening telescopic rod, two spring sheets are arranged opposite to each other, and the clamping drive source enables the two spring sheets to clamp the bar material;

[0038] The point detection component includes a support plate, an infrared transmitter and an infrared receiver. The support plate is connected to the frame. The infrared transmitter and the infrared receiver are both connected to the support plate. The infrared transmitter and the infrared receiver are arranged opposite to each other. The infrared receiver is used to receive the signal sent by the infrared transmitter. The bar passes between the infrared transmitter and the infrared receiver.

[0039] By adopting the above technical solution, when the rod passes between the infrared transmitter and the infrared receiver, the rod can block the infrared receiver from receiving the signal emitted by the infrared transmitter, which indicates that the rod has reached the predetermined point. The clamping drive source drives the spring clip to clamp the rod by pressing the telescopic rod, and then the moving slide drives the rod to move in the direction close to the accommodating ring seat, so that the ends of the two sections of the rod are pressed tightly, which is beneficial to the subsequent welding operation.

[0041] 1. The rotating drive source drives the rotating gear ring to rotate, and the rotating gear ring drives the supporting base block to slide along the guide ring rail, so that the welding gun rotates around the bar material, realizing uniform welding of the bar material in the circumferential direction, improving the welding quality and stability; the telescopic drive source can make the welding gun move towards or away from the bar material, so that bars of different diameters can be welded, improving adaptability;

[0042] 2. Before welding, the grinder removes the copper layer on the surface of the bar material, which can improve the subsequent welding performance. After welding, the driving source pushes the grinder so that the grinder applies a clamping force to the bar material. The pressure sensor detects the clamping force applied to the bar material. The pressure sensor detects whether the clamping force reaches the predetermined detection value, thereby judging whether the bar material welding meets the standard. If the welding does not meet the standard, repair welding is required. If the welding meets the standard, the grinder grinds the welding area of ​​the bar material to remove welding slag and burrs, making the welding area of ​​the bar material smoother;

[0043] 3.

In this embodiment, the moving slide 31 specifically adopts a linear module, the clamping drive source 321 specifically adopts an electric push rod, and the close telescopic rod 322 specifically adopts a gas spring. The moving slide 31 is fixedly connected to the frame 1, and the clamping drive source 321 is fixedly connected to the moving slide 31, and the moving slide 31 can drive the clamping drive source 321 to move in a direction close to the accommodating ring seat 41. The close telescopic rod 322 is fixedly connected to the output shaft of the clamping drive source 321, and the spring 323 is fixedly connected to the end of the close telescopic rod 322. The spring 323 is arranged oppositely, and the clamping drive source 321 drives the close telescopic rod 322 to move in a direction close to the rod material, so that the two springs 323 clamp the rod material. There are two groups of abutment mechanisms 3, which are respectively located on both sides of the welding mechanism 4. The two groups of abutment mechanisms 3 correspond to the two sections of bar materials one by one, and the movable slide 31 can drive the two ends of the bar materials to abut against each other.

[0074] The implementation principle of a copper-clad steel welding device in Example 2 of the present application is as follows: the transport component 2 transports the bar material. When the infrared receiver 333 does not receive the light signal emitted by the infrared transmitter 332, it indicates that the end of the bar material is located at a predetermined point, and the transport component 2 stops transporting. The clamping drive source 321 clamps the bar material by pressing against the telescopic rod 322 so that the spring 323 clamps the bar material, and the moving slide 31 moves the bar material toward the receiving ring seat 41 until the ends of the two sections of the bar material abut against each other. The abutment mechanism 3 can make the abutment and alignment of the ends of the two sections of the bar material more precise, and make the abutment of the ends of the two sections of the bar material more compact, thereby improving the accuracy of the ends of the bar material when docking.
