Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, specifically to an extended translational tube welding machine. Background Technology

[0002] The radiators in adiabatic coolers are mostly finned tube radiators. The production steps of finned tube radiators include assembling fins and heat dissipation tubes into heat dissipation units, and then welding the heat dissipation units together to form the entire radiator. When assembling the heat dissipation units, tube sheets are first installed on their end faces, and then the inward-facing openings of the zigzag tube box are welded to the tube sheets. During welding, all joints between the tube box and the tube sheet need to be welded. While the joints on the outside of the tube box can be welded manually, welding the inside is more difficult. Furthermore, due to the relatively narrow and long inner cavity of the tube box, traditional welding methods cannot achieve internal seam welding, and the quality and efficiency of the welding cannot be guaranteed. This results in the tube box welding operation being time-consuming, costly, and of poor quality. This utility model provides an extended translational tube cavity welding machine to solve the above problems. Utility Model Content

[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] In the description of this utility model, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] like Figure 1 , 2 As shown in Figure 3, an extended translational tube welding machine includes a frame 1, a translation component 2, an extension rod 3, a welding machine 4, a wire feeder 5, a welding torch 6, and a control system. The translation component 2 is mounted on the frame 1, the extension rod 3 is horizontally mounted on the translation component 2, and the welding torch 6 is located at the outer end of the extension rod 3. The extension rod 3 and the welding torch 6 move together with the translation component 2. The welding machine 4 is fixedly mounted on the frame 1, and the wire feeder 5 is fixedly mounted on the translation component 2. The welding torch 6 is connected to the welding machine 4 and the wire feeder 5. The control system is connected to the frame 1, the translation component 2, the welding machine 4, and the wire feeder 5, and controls the lifting and lowering of the lifting support leg assembly 11 in the frame 1, the translation of the translation slide 21 in the translation component 2, the rotation of the rotating support 22, and the start and stop of the welding machine 4 and the wire feeder 5.

[0025] like Figure 1 , 2As shown in Figure 3, the welding equipment of this utility model is used for welding seams in narrow and long pipe cavities. Due to the extremely small space and long length of the narrow and long pipe cavity, conventional welding torches cannot be inserted into the cavity. Even if a welding torch can be inserted into the cavity, the welding process cannot be guaranteed to be stable and continuous, thus failing to ensure that the weld quality meets the requirements. This utility model uses the cooperation of the translation component 2 and the extension rod 3 to send the welding torch 6 into the narrow and long pipe cavity, and the translation component 2 achieves a stable, uniform, and continuous insertion process, thereby ensuring the quality of the weld. The operating principle of this utility model is to set the welding torch 6 at the outer end of the extension rod 3, and set the extension rod 3 on the translation slide 21. The translation slide 21 is set on the slide seat 13 on the worktable 12. During welding, the translation slide 21 moves on the slide seat 13, thereby smoothly sending the extension rod 3 and the welding torch 6 into the pipe cavity for welding operations.

[0026] like Figure 1 , 4 As shown in Figure 5, the translation component 2 further includes a translation slide 21, a rotary support 22, and a limiting support 23. The translation slide 21 is movably mounted on the slide 13 of the frame 1 and moves back and forth on the slide 13. The rear end of the extension rod 3 is connected to the translation slide 21 through a bearing and a bearing seat, and moves back and forth together with the translation slide 21. The rotary support 22 is fixedly mounted on the translation slide 21. The limiting support 23 is fixedly mounted at the front end of the frame 1. The rear part of the extension rod 3 is connected to the rotary support 22. Driven by the rotary support 22, the extension rod 3 swings around its own axis. The front part of the extension rod 3 is supported on the limiting support 23. The front part of the extension rod 3 is placed on the limiting support 23 to support the extension rod 3, keep the extension rod 3 horizontal, and ensure the stability of the extension rod 3 when it moves and swings.

[0027] like Figure 4 , 5 As shown, further, due to the arrangement of the pipeline, the rotation range of the extension rod 3 around the axis is small, and the total range of left and right swing is no more than 120°. A rotating support 22 is set to adjust the left and right orientation of the extension rod 3, thereby changing the angle of the welding gun 6 at the end of the extension rod 3. The rotating support 22 includes a collar and a driver. The collar is sleeved on the extension rod 3, and the driver is set on the translation slide 21 and connected to the collar.

[0028] like Figure 4As shown, preferably, the driver is a motor and a worm gear located on the output end of the motor. The worm gear is set perpendicular to the extension rod 3 and located below the extension rod 3. A collar is sleeved on the extension rod 3. The outer side of the collar has gear teeth that mesh with the worm gear to form a worm gear structure. Driven by the motor, the forward and reverse rotation of the worm gear drives the collar to swing left and right, adjusting the offset angle of the extension rod 3, and thus adjusting the orientation of the welding torch 6 at the front end of the extension rod 3, so that the welding torch 6 can adapt to the direction of the weld.

[0029] like Figure 6 As shown, the limiting support 23 further includes a base and a track wheel. The base is fixedly mounted on the workbench 12, and the track wheel is movably mounted on the base. The track wheel facilitates the translation of the extension rod 3, and also plays a limiting role when the extension rod 3 is rotated and offset.

[0030] like Figure 1 , 6 As shown, the frame 1 further includes a lifting leg assembly 11, a worktable 12, and a slide 13. The worktable 12 is mounted on the lifting leg assembly 11, and the lifting leg assembly 11 is used to adjust the height of the worktable 12 so that the height of the welding torch 6 is consistent with the height of the weld. The slide 13 is mounted on the worktable 12, and the translational slide 21 is movably mounted on the slide 13 and can move back and forth along the slide 13.

[0031] like Figure 1 , 6 As shown, the lifting outrigger assembly 11 further includes a base frame 111, a lifting mechanism 112, a linkage rod 113, and a power unit 114. The lifting mechanisms 112 are arranged in pairs on the base frame 111, and the work platform 12 is located at the top of the lifting mechanism 112. The linkage rod 113 is horizontally arranged on the base frame 111 and is connected to the lifting mechanism 112, connecting the two lifting mechanisms 112 into one unit and driving the two lifting mechanisms 112 to move together, controlling the work platform 12 to move up and down. The power unit 114 is connected to the rear lifting mechanism 112 and drives the rear lifting mechanism 112 to move.

[0032] Furthermore, the bottom of the base frame 111 is equipped with self-locking casters for moving equipment and adjusting the orientation of the equipment.

[0033] Furthermore, the lifting platform 112 is a worm gear screw jack. The rear lifting platform 112 is directly connected to the power unit 114. The front and rear lifting platforms 112 are connected by a linkage rod 113. When the rear lifting platform 112 moves, it drives the front lifting platform 112 to move synchronously through the linkage rod 113.

[0034] Furthermore, the extension rod 3 is a hollow round tube, and the welding wire of the wire feeder 5 passes through the extension rod 3 and extends to the welding gun 6.

[0035] Furthermore, the translation slide 21 is equipped with a second power device to drive the translation slide 21 to move back and forth on the slide block 13.

[0036] like Figure 1 , 2 As shown in Figure 3, a welding method for an extended translational tube welding machine includes the following steps:

[0037] S1, Equipment Adjustment: Control the translation slide 21 to reset, control the lifting support leg assembly 11 to adjust the equipment height, ensure that the equipment is in a horizontal state, and make the height of the welding torch 6 the same as the height of the weld.

[0038] S2, Welding preparation: After adjusting the height appropriately, align the welding torch 6 with the front end of the weld seam, manually move the welding equipment so that the extension rod 3 is parallel to the weld seam, that is, keep the axis of the extension rod 3 parallel to the weld seam, lock the welding equipment to prevent the welding equipment from shifting, and then adjust the welding angle of the welding torch 6 by adjusting the angle of the extension rod 3, that is, adjust the orientation of the welding torch 6 so that it is aligned with the weld seam.

[0039] S3, Welding operation: Start the welding machine 4 and wire feeder 5, control the translation slide 21 to move forward at a constant speed along the slide 13, drive the extension rod 3 and the welding gun 6 on it to move, send the welding gun 6 into the narrow tube cavity, and weld the inner corner.

[0040] S4, Repeat the operation: After the first inner corner weld is completed, stop the machine and reset it. Adjust the position and angle of the welding gun 6 according to the operation of step S2 so that it is aligned with the second inner corner weld. Then, weld the second inner corner weld according to the operation of step S3. After welding is completed, stop the machine and reset it.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
