[0041] The purpose of the present invention is to provide a stainless steel gutter welding device and a welding method, which can realize fully automated high-precision welding of stainless steel gutters and drainage pipes to solve the problems existing in the prior art.

[0042] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

The support fixing plate 10 is fixedly connected with the mounting bracket 5 and is located below the rotating control plate 6. The support fixing plate 10 is coaxial with the rotating control plate 6. The connecting movable frame 8 is cylindrical, and its bottom end is embedded in the circular ring of the support fixing plate 10 and rolls with the inner wall of the circular ring of the support fixing plate 10. The center of the support fixing plate 10 is coaxially provided with a guide ring seat 11. A support rod 12 is fixedly connected to one side of the support fixing plate 10. The support rod 12 is fixed to the mounting bracket 5, and a first telescopic controller 13 is installed at the lower end of the support rod 12. The lower end of the first telescopic controller 13 is fixedly connected to a docking fixing frame 14. The external mechanical arm takes the drain pipe, puts it into the center of the guide ring seat 11, and reaches the top of the stainless steel gutter 4. At the same time, the first telescopic controller 13 controls the lifting and lowering adjustment of the support rod 12 to fine-tune the height of the entire argon arc welding processing structure 1. After that, the wire feeding seat 15 and the welding gun 16 work to contact the connection position of the stainless steel gutter 4 and the drain pipe to weld the stainless steel gutter 4 and the drain pipe.

[0045] like Figure 2 , Figure 6 and Figure 7As shown, the pressing limit structure 2 includes a rotation control shaft 17, a connecting guide rod 18, a contact sleeve 19, a matching base frame 20, a fixed block plate 21, an electric telescopic guide rod 22, a front guide plate 23 and a connecting shaft frame 24. The front end of the matching base frame 20 is fixedly connected to the fixed block plate 21, and the front guide plates 23 are fixedly connected to both sides of the fixed block plate 21. The front guide plate 23 is hinged with an electric telescopic guide rod 22, and the upper end of the electric telescopic guide rod 22 is hinged with a connecting shaft frame 24. The rear end of the rotation control shaft 17 is hingedly set on the matching base frame 20, and the front end of the rotation control shaft 17 passes through the connecting shaft frame 24 and is fixedly connected to the connecting guide rod 18. The rotation control shaft 17 is fixedly connected to the connecting shaft frame 24. The contact sleeve 19 is mounted on the connecting guide rod 18. The aforementioned first telescopic controller 13 is fixed to the middle of the matching base frame 20 through the docking fixed frame 14. When the motor 31 is working, it can drive the rotating control disk 6 to rotate, and the rotating control disk 6 drives the connecting movable frame 8 to rotate, so that the connecting movable frame 8 drives the argon arc welding machine 7 to rotate together, and the inner wall of the circular ring of the supporting fixed disk 10 guides and limits the rotation of the connecting movable frame 8. When the argon arc welding machine 7 rotates, it can drive the shading camera 9, the welding wire feeding seat 15, and the welding gun 16 to rotate in a circle together, so as to perform annular welding work under the supporting fixed disk 10 (the formed annular weld is coaxial with the supporting fixed disk 10), and realize the docking and fixing of the stainless steel gutter 4 and the drainage pipe. During the welding process of the welding gun 16, the shading camera 9 takes real-time photos of the welding situation, and the outer cover of the shading camera 9 is provided with a shading film sleeve to perform shading work.

[0046] The stainless steel gutter 4 reaches the front end position under the conveying action of the conveying structure 3. At this time, the stainless steel gutter 4 is located below the supporting fixed plate 10. The front end of the stainless steel gutter 4 abuts against the fixed block plate 21 to limit the position. At the same time, the electric telescopic guide rod 22 is retracted and adjusted, so that the electric telescopic guide rod 22 drives the rotation control shaft 17 to rotate through the connecting shaft frame 24, thereby changing the position of the rotation control shaft 17, and then changing the height of the contact sleeve 19 on the connecting guide rod 18 relative to the stainless steel gutter 4. After adjusting to the position where the contact sleeve 19 presses against the top of the stainless steel gutter 4, the electric telescopic guide rod 22 stops retracting, and the position of the contact sleeve 19 is fixed, thereby pressing and fixing the stainless steel gutter 4. After the welding is completed, the electric telescopic guide rod 22 is started to retract and adjust, so that the contact sleeve 19 is higher than the stainless steel gutter 4, and the pressing limit structure 2 releases the downward limit of the stainless steel gutter 4. At this time, the conveying structure 3 reverses the transmission of the stainless steel gutter 4, so that the stainless steel gutter 4 is separated.

[0047] like Figure 1 , Figure 2 and Figure 8As shown, the transmission structure 3 includes a guide transmission roller 25, a contact roller 26, a telescopic control frame 27, a second telescopic controller 28, a matching reinforcement guide seat 29 and a support frame 30. Two groups of support frames 30 are arranged at intervals. A matching reinforcement guide seat 29 is fixedly connected to each group of support frames 30. A transmission channel consistent with the length direction of the stainless steel gutter 4 is formed between the two matching reinforcement guide seats 29. A plurality of guide transmission rollers 25 are arranged in parallel in the transmission channel. Both ends of any guide transmission roller 25 are respectively connected to the two matching reinforcement guide seats 29 for rotation. The ends of all guide transmission rollers 25 are sleeved with a power transmission belt on the outside. The power transmission belt is an existing transmission power part, which is itself equipped with a driving source such as a motor. The driving source drives the power transmission belt to transmit, and then drives each guide transmission roller 25 to roll in the same direction, so as to realize the transmission of the stainless steel gutter 4 on the guide transmission roller 25. Each of the coordinated reinforcement guide seats 29 is fixedly connected with a second telescopic controller 28, and the telescopic end of the second telescopic controller 28 is connected to a contact roller 26 through a telescopic control frame 27, and the telescopic end of each second telescopic controller 28 is connected to a row of contact rollers 26 along the transmission direction of the guide transmission roller 25, and the axis of each contact roller 26 is parallel to the transmission direction of the guide transmission roller 25. Figure 8 As shown, the second telescopic controller 28 can drive the contact roller 26 to move toward the opposite matching reinforcement guide seat 29, so that the two sets of second telescopic controllers 28 can be used to adjust the spacing between the two rows of contact rollers 26, so that the two rows of contact rollers 26 are respectively matched with the gaps on both sides of the stainless steel gutter 4, so that the two rows of contact rollers 26 are used to limit the stainless steel gutter 4, ensuring that the stainless steel gutter 4 is located in the middle of the guide transmission roller 25. In the initial state, the stainless steel gutter 4 is placed on the guide transmission roller 25 on the conveying structure 3, and the positions of the two rows of contact rollers 26 can be changed by reciprocating telescopic operation of the two sets of second telescopic controllers 28, so that the contact rollers 26 push the stainless steel gutter 4 until the stainless steel gutter 4 is in the middle of the guide transmission roller 25 for transmission.

[0048] The two supporting frames 30 are respectively located at the front ends of the two front guide plates 23 and are fixedly connected to the front guide plates 23 .

[0049] The welding method and working principle of the stainless steel gutter welding equipment 100 are as follows:

[0050] When in use, the user places the stainless steel gutter 4 on the guide transmission roller 25 on the conveying structure 3. As the guide transmission roller 25 rotates, the stainless steel gutter 4 is driven to transmit. The rotation of the guide transmission roller 25 is controlled by an independent motor. At the same time, the second telescopic controller 28 works to drive the telescopic control frame 27 to extend and retract, changing the position of the contact roller 26 so that the contact roller 26 pushes the stainless steel gutter 4 to ensure that the stainless steel gutter 4 is in the middle position of the guide transmission roller 25 for transmission. The stainless steel gutter 4 reaches the front end position, at which time the front end of the stainless steel gutter 4 contacts the fixed block plate 21 for limiting, and at the same time the electrically-controlled telescopic guide rod 22 contracts and adjusts, so that the electrically-controlled telescopic guide rod 22 changes the position of the rotating control shaft 17 through the connecting shaft frame 24, until the contact sleeve 19 contacts the stainless steel gutter 4 to limit the stainless steel gutter 4. At this time, the external mechanical arm takes the drain pipe and puts it into the center of the guide ring seat 11. After the bottom end of the drain pipe reaches the upper end of the stainless steel gutter 4, the first telescopic controller 13 controls the telescopic adjustment of the support rod 12 to fine-tune the height of the argon arc welding processing structure 1, and then the welding wire feeding seat 15 and the welding gun 16 work to contact the stainless steel gutter 4 and the drain pipe. The water pipe connection position is contacted to carry out welding work, and at the same time, the motor 31 is working, which can drive the rotating control disk 6 to rotate, and act on the connecting movable frame 8, so that the connecting movable frame 8 drives the argon arc welding machine 7 to rotate together, and the argon arc welding machine 7 can drive the shading camera 9, the welding wire feeding seat 15, and the welding gun 16 to rotate together to perform circular welding work, so as to realize the docking and fixation of the stainless steel gutter 4 and the drainage pipe, and at the same time, the shading camera 9 performs real-time photography, and the outer cover of the shading camera 9 is provided with a shading film cover to perform shading work. After welding is completed, the limit structure 2 is adjusted and pressed to cancel the limit, and at the same time, the guide transmission roller 25 of the transmission structure 3 reverses the transmission, so that the stainless steel gutter 4 is detached, and the work is completed.

[0051] It can be seen that the above-mentioned stainless steel gutter welding equipment 100 proposed in this scheme can perform specific welding work through the structural setting of the argon arc welding processing structure. The motor can control the rotation control disk to rotate, so that the argon arc welding machine and the connecting movable frame at the lower end follow the rotation. The argon arc welding machine and the connecting movable frame are rotationally guided and limited by the supporting fixed disk. At the same time, the position of the guide ring seat can be placed on the drain pipe through the mechanical arm, so that the drain pipe and the stainless steel gutter are combined. With the rotation of the argon arc welding machine, the welding wire feeding seat and the welding gun follow the rotation to perform the welding processing work of the drain pipe and the stainless steel gutter. At the same time, the first telescopic controller can control the height of the support rod to adjust the overall height of the argon arc welding processing structure, thereby reducing labor and realizing automated argon arc welding processing work.

[0052] The above-mentioned stainless steel gutter welding equipment 100 proposed in this scheme, through the structural setting of the pressing limit structure, the rotation control shaft in the pressing limit structure is hingedly set with the matching base frame, and the electric control telescopic guide rod can drive the connecting shaft frame and the rotation control shaft to rotate through telescoping, thereby changing the position of the connecting guide rod and the contact sleeve, so that the contact sleeve contacts the stainless steel gutter to limit the stainless steel gutter. The second telescopic controller in the transmission structure changes the position of the contact roller through the telescopic control frame, so that the contact roller pushes the stainless steel gutter, ensuring that the stainless steel gutter is transmitted and controlled at the center position of the guide control roller.

[0053] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
