Description

Technical Field

[0001] This utility model relates to welding equipment, specifically to a dual-head vertical welding integrated machine. Background Technology

[0002] The side panels and corner posts of the container overlap to form a vertical weld. Welding is performed from top to bottom using a rapid lifting welding method. Traditional welding involves manually ascending a lift to the welding apex, then using a handheld welding torch. During the welding process, the lift automatically descends at a constant speed. Manual welding is inefficient and produces inconsistent weld quality.

[0003] The applicant previously designed an intelligent welding device for vertical welds of containers (publication number CN106077905B) with weld recognition, which automates the entire process and replaces manual welding. Although this patent greatly improves welding efficiency, the use of a single welding torch means that for long vertical welds, the welding operation is inevitably time-consuming as it is done from top to bottom with a single welding torch. There is room for further design optimization. Utility Model Content

[0004] This utility model discloses a dual-head vertical welding integrated machine, which adopts a dual-head welding gun with up-and-down linkage control to simultaneously weld vertical seams, resulting in higher welding efficiency compared to single-head welding gun equipment.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A dual-head vertical welding machine includes a column, a vertical guide rail mounted on the column, an upper head assembly and a lower head assembly mounted on the column and moving synchronously up and down along the vertical guide rail, and a drive mechanism for driving the upper head assembly to move up and down. The upper head assembly and the lower head assembly are connected by a connecting rod. The drive mechanism includes a double-stage worm gear reducer and a sprocket. The sprocket is mounted on the output end of the double-stage worm gear reducer. A chain is provided between the drive mechanism and the upper head assembly. The chain meshes with the sprocket and is also fixedly connected to the upper head assembly. The upper head assembly is equipped with an upper welding gun, and the lower head assembly is equipped with a lower welding gun. The upper welding gun and the lower welding gun are located on the same side and their vertical positions correspond to each other.

[0007] Furthermore, the column is also equipped with a counterweight. The fixed ends of the counterweight and the chain on the upper head assembly are located on two opposite sides of the column. The counterweight is fixedly connected to the chain. Through the rotation of the sprocket, the counterweight and the upper head assembly are driven to move up and down in opposite directions.

[0008] Furthermore, both the upper and lower welding guns can be adjusted in position along two vertical directions.

[0009] Furthermore, the upper head assembly includes an upper top plate connected to a chain, a column slide plate mounted on a vertical guide rail, a slider on the side of the column slide plate facing the guide rail, and the slider sliding along the guide rail; a fixed plate is provided at the bottom of the upper top plate, a first guide rail is horizontally mounted on the fixed plate, a first slide plate with a slider is mounted on the first guide rail, the first slide plate is connected to a horizontal fixed frame, an upper welding gun is mounted at one end of the fixed frame, a first push rod motor is provided on one side of the fixed plate, the first push rod motor is used to drive the first slide plate to move along the first guide rail; a second slide plate is fixedly mounted on the side of the column slide plate away from the guide rail, a second guide rail is horizontally mounted on the outer side of the second slide plate, a slider is mounted on the second slide plate, the second slide plate moves along the second guide rail via the slider, one end of the second guide rail is mounted on the fixed plate, and a second push rod motor is provided at the other end of the second guide rail, the second push rod motor is used to push the second guide rail to move horizontally relative to the second slide plate.

The upper and lower machine head components are connected together by a connecting rod. The upper machine head component is driven to rise and fall by a drive mechanism, realizing the up and down linkage operation of the dual-head welding gun. It can simultaneously weld different positions of the vertical weld seam, which greatly improves the welding efficiency. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] This embodiment discloses a dual-head vertical welding integrated machine, such as... Figures 1 to 5 As shown, the main components include a column 1, with vertical guide rails on two opposite surfaces. A drive mechanism 4 is located at the top of the column 1. In this embodiment, the drive mechanism 4 includes a double-stage worm gear reducer 401 and a sprocket 402, with the sprocket 402 mounted at the output end of the double-stage worm gear reducer 401. An upper welding head assembly 5 and a lower welding head assembly 6 are vertically arranged along the top of the column 1, with the upper welding head assembly 5 located above the lower welding head assembly 6. Each of the two welding head assemblies is equipped with a welding torch, and the upper welding torch 501 and the lower welding torch 61 are located on the same side and correspond vertically.

[0020] The upper head assembly 5 and the lower head assembly 6 have similar structures. The positions of the welding guns on both assemblies can be adjusted in both horizontal and vertical directions. For the sake of simplicity, the position adjustment mechanism of the upper head assembly 5 will be described below with reference to the attached drawings.

[0021] The upper head assembly 5 includes an upper top plate 502 and a column slide plate 510. The column slide plate 510 is located below the upper top plate 502. A slider is provided on the side of the column slide plate 510 facing the vertical guide rail of the column, and the slider slides along the vertical guide rail. A fixing plate 505 is horizontally arranged on the adjacent surface of the vertical guide rail of the column 1. The fixing plate 505 is located below the upper top plate 502. A first guide rail (not labeled in the attached figure) is horizontally arranged on the fixing plate 505. A first slide plate 504 with a slider is arranged on the first guide rail. A horizontal fixing frame 503 is provided on the outer side of the first slide plate 504. The fixing frame 503 is fixed on the first slide plate 504. A welding gun 501 is installed at one end of the fixing frame 503. A first push rod motor 506 is provided on one side of the fixing plate 505. The first push rod motor 506 is used to drive the first slide plate 504 to reciprocate along the first guide rail to adjust the left and right position of the welding gun 501. A second slide plate 508 is fixedly installed on the side of the column slide plate 510 away from the vertical guide rail. A second horizontal guide rail 507 is provided on the outer side of the second slide plate 508. A slider is provided on the second slide plate 508, and the second slide plate 508 moves horizontally back and forth along the second guide rail 507 by means of the slider. One end of the second guide rail 507 is fixedly installed on the fixed plate 505, and the other end of the second guide rail 507 is provided with a second push rod motor 509. The second push rod motor 509 is used to push the second guide rail 507 to move horizontally relative to the second slide plate 508, thereby realizing the adjustment of the front and back position of the upper welding gun 501.

[0022] A chain 3 is provided between the drive mechanism 4 and the upper top plate 502. The bottom of the chain 3 is fixed to the upper top plate 502, and the chain 3 meshes with the sprocket 402. A counterweight 2 is also provided on the side of the column 1 opposite to the surface of the column slide plate 510. The counterweight 2 is fixedly connected to the chain 3. The counterweight 2 moves up and down along the guide rail on the column 1. Through the transmission of the double-stage worm gear reducer 401, it can pull the upper head assembly 5 up and down, so that the counterweight 2 and the upper head assembly 5 move in opposite directions. The lower head assembly 6 also includes a lower top plate 62. In order to realize the linkage lifting control of the upper head assembly 5 and the lower head assembly 6, a lower sleeve is provided on the top surface of the lower top plate 62, and an upper sleeve is provided on the column slide plate 510 in the upper head assembly 5. The upper sleeve and the lower sleeve are fixedly connected by a connecting rod 7.

[0023] Since the upper head assembly 5 and the lower head assembly 6 are linked vertically, for the sake of simplicity, we will take the movement of the upper head assembly 5 in different directions as an example to illustrate that the head assembly of the present invention can adjust its position in multiple dimensions.

[0024] Explanation of the vertical movement of the upper welding gun 501 along the column 1: The column slide plate 510 is located below the upper top plate 502 and the two are fixedly connected. A vertical guide rail is provided on the column 1 on the side where the column slide plate 510 is located. A slider is provided on the side of the column slide plate 510 facing the vertical guide rail. The slider can slide up and down along the vertical guide rail. When the sprocket 402 rotates, the chain 3 can drive the upper top plate 502 to move up and down along the column 1, thereby realizing the vertical movement of the upper welding gun 501 on the upper head assembly 5.

[0025] 501 welding torch edge Figure 3 Explanation of left and right movement: A fixing plate 505 is provided below the upper top plate 502. The fixing plate 505 is a horizontal plate with a first horizontal guide rail on it. A first sliding plate 504 with a slider is provided on the outer side of the first guide rail. The first sliding plate 504 can move horizontally left and right along the first guide rail by the slider. A horizontal fixing frame 503 is fixedly installed on the outer surface of the first sliding plate 504, and the upper welding gun 501 is installed on the fixing frame 503. Figure 3 The right end shown is on the fixing plate 505. Figure 3 The right end is shown to be equipped with a first push rod motor 506, which can push the first slide plate 504 to move laterally along the first guide rail. According to the above structural configuration, the upper welding gun 501 is able to move laterally. Figure 3 The movement is shown in the left and right directions.

[0026] 501 welding torch edge Figure 3Explanation of the forward and backward movement shown: A second slide plate 508 is fixedly installed on the outer surface of the column slide plate 510. The second slide plate 508 has a slider, and a transverse second guide rail 507 is provided on the outer side of the second slide plate 508. The slider of the second slide plate 508 can slide along the second guide rail 507. The right end of the second guide rail 507 is fixed to the fixed plate 505, and a second push rod motor 509 is provided on the left side of the second guide rail 507. The second push rod motor 509 is used to push the second guide rail 507. At this time, the relevant components mentioned in the above description of the left and right movement of the welding gun 501 and the fixed plate 505 can be regarded as a whole. Since the second guide rail 507 is fixed to the fixed plate 505, and the second slide plate 508 and the column slide plate 510 are relatively fixed, when the second push rod motor 509 pushes the second guide rail 507 to move away from the column 1 (i.e., Figure 4 (As shown, moving to the right) achieves the movement of the upper welding gun 501 relative to the column 1 in the front-back direction.

[0027] Through the description of the movement of the welding torch 501 in the above three directions, it can be seen that the two sets of welding torches of this utility model, in order to Figure 3 As shown in the direction reference, the welding torch can be adjusted in position up and down, left and right, and forward and backward. The left and right position adjustment can adjust the position of the welding torch between vertical weld seams at different intervals. The forward and backward position adjustment can make the welding torch head aligned with and close to the vertical weld seam. The up and down position adjustment can make the welding torch perform vertical welding operations along the vertical weld seam. Therefore, the welding head of this utility model can realize multi-dimensional movement.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
