Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and descriptions of this utility model are used to explain the present utility model, but are not intended to limit the present utility model.

[0026] refer to Figures 1 to 6 ,like Figure 1 and Figure 2As shown, this embodiment provides a TIG dual-gun welding device for spiral coil cylinders, which can effectively improve the welding quality and efficiency of spiral coil cylinders 10. The welding device includes a base 1, a welding mechanism 2, a pair of roller frames 4, and a welding control cabinet 8. The right end surface of the base 1 is provided with a U-shaped support 7. The pair of roller frames 4 are coaxial and oppositely arranged. The front roller frame 4 is slidably connected to a pair of travel tracks 3 of the base 1, and the rear roller frame 4 is fixed to the support 7 of the base 1. The front roller frame 4 can slide on the pair of travel tracks 3. The operator pushes the front roller frame 4 to move the front roller frame 4 relative to the rear roller frame 4, thereby adjusting the distance between the two roller frames 4. This allows the device to adapt to spiral coil cylinders 10 of different lengths, enhancing the versatility of the device. Welding mechanism 2 is mounted above base 1 and located on one side of a pair of roller frames 4. Welding mechanism 2 includes an X-axis moving mechanism 201, a Z-axis moving mechanism 202, and a welding torch mounting frame 21. The welding torch mounting frame 21 is mounted on the Z-axis moving mechanism 202, and a pair of TIG welding torches 22 are mounted on the welding torch mounting frame 21. The X-axis moving mechanism 201 controls the movement of the TIG welding torches 22 along the travel track 3, and the Z-axis moving mechanism 202 controls the vertical lifting and lowering of the TIG welding torches 22. Welding control cabinet 8 is mounted on base 1 and located on one side of welding mechanism 2. Welding power supply is located on one side of welding control cabinet 8. Welding control cabinet 8 is equipped with a PLC. The PLC integrates multiple control functions and can achieve precise control of the welding process, including adjustment of welding parameters and operation control of the welding mechanism, thereby ensuring the stability and reliability of welding quality.

[0027] Among them, a pair of roller frames 4 are used to support the spiral coil body 10 and drive its rotation so that a pair of TIG welding guns 22 can perform welding operations on the coil 10 on the body.

[0028] Typically, the TIG welding torch 22 setting can improve welding efficiency and quality, and is suitable for high-precision, high-requirement industrial scenarios.

[0029] In the embodiments of this application, such as Figure 4 , Figure 5As shown, the roller frame 4 includes a support plate 61, a housing 62, a cover plate 63, a pair of support modules, a drive motor 671, and an adjustment assembly. The housing 62 is a box-type structure with an open top and is installed above the support plate 61. Four sliding blocks 611 are symmetrically arranged on both sides of the bottom of the support plate 61 at the front end of the roller frame 4, with a pair of sliding blocks 611 symmetrically installed on each side. The sliding blocks 611 slide in cooperation with the corresponding travel track 3. The support plate 61 at the end of the roller frame 4 is installed on the upper surface of the support 7. The cover plate 63 is detachably fitted into the opening of the housing 62, facilitating inspection and maintenance of the components inside the housing 62. A pair of support modules are symmetrically arranged on the surface of the cover plate 63 to support the spiral coil cylinder 10. The drive motor 671 is fixedly installed on the outer wall of the housing 62. The adjustment assembly is installed inside the housing 62 and is driven by the drive motor 671. Both ends of the adjustment assembly are connected to the corresponding support modules.

[0030] like Figure 4 As shown, the adjustment assembly includes a gear 672, a first moving module, and a second moving module. The gear 672 is coaxially fixed to the end of the output shaft of the drive motor 671. The first moving module includes a first rack 673 that meshes with the gear 672 and a first protruding plate 675 fixed to the right end of the first rack 673. The second moving module includes a second rack 674 that meshes with the gear 672 and a second protruding plate 676 fixed to the left end of the second rack 674. The gear 672, the first rack 673, and the second rack 674 are all located inside the housing 62. The first protruding plate 675 extends upward from inside the housing 62 and connects to the corresponding base plate 66. The second protruding plate 676 also extends upward from inside the housing 62 and connects to the corresponding base plate 66. The gear and rack transmission method has the advantages of smooth transmission and high precision, which can ensure that the first convex plate 675 and the second convex plate 676 move according to a predetermined pattern, thereby realizing precise adjustment of the position of the support module to adapt to the welding of spiral coil cylinders 10 with different diameters, greatly enhancing the versatility and flexibility of the device.

[0031] refer to Figure 4 The support module includes a base plate 66, a pair of support frames 64, support rollers 65, and a tilting motor 69. The base plate 66 is mounted on top of corresponding first and second protrusions 675, and its position can be adjusted as the first and second protrusions 675 move. The base plate 66 slides in contact with the cover plate 63. The pair of support frames 64 are vertically and spaced apart and fixed to the surface of the base plate 66. The support rollers 65 are rotatably mounted between the pair of support frames 64, supporting the spiral coil cylinder 10 while ensuring smooth rotation of the cylinder, reducing friction, and improving welding efficiency and quality. The tilting motor 69 is mounted on one of the support frames 64, and its output shaft is connected to the support rollers 65 to drive the spiral coil cylinder 10 to rotate.

[0032] In one embodiment, reference Figure 4 A pair of horizontally fixed guide rods 677 are installed on both the left inner sidewall and the left inner sidewall of the housing 62. The first convex plate 675 and the second convex plate 676 are respectively slidably engaged with the corresponding guide rods 677. An end plate 678 is installed at the end of the guide rod 677 to limit the first convex plate 675 or the second convex plate 676.

[0033] In one embodiment, such as Figure 3 As shown, the front roller frame 4 is equipped with a locking element, specifically a knurled screw 68. An anti-loosening washer 681 is fitted onto the knurled screw 68. The knurled screw 68 is threaded onto the sliding block 611, and passes through the sliding block 611 to abut against the corresponding travel track 3. The design of the knurled screw 68 allows the operator to easily tighten and loosen it manually, facilitating locking or unlocking the sliding block 611 and the corresponding travel track 3. The anti-loosening washer 681 effectively prevents the knurled screw 68 from loosening in the locked state, thus ensuring that the front roller frame 4 is firmly locked onto the travel track 3 after being adjusted to the appropriate position, preventing movement during welding and ensuring the stability and quality of the welding process.

[0034] Preferably, a pair of running tracks 3 are fixedly mounted in parallel on the surface of the base 1, providing precise guidance for the movement of the front roller frame 4. Figure 3 , Figure 6 As shown, the traveling track 3 adopts an I-shaped structure, which has the advantages of high strength and good stability. The bottom center of the sliding block 611 has a cavity 6111 that can accommodate the traveling track 3. The two outer side walls of the traveling track 3 are provided with grooves 31, and the lower end of the sliding block 611 is provided with a pair of protrusions 6112. The protrusions 6112 slide and engage with the corresponding grooves 31, making the connection between the sliding block 611 and the traveling track 3 tighter and reducing shaking and deviation during movement. The upper inner wall of the cavity 6111 is also symmetrically provided with a pair of rotating wheels 6113. The rotating wheels 6113 contact the inner bottom wall of a pair of rolling grooves 32 corresponding to the top of the traveling track 3, further enhancing the stability and accuracy during movement and ensuring that the front roller frame 4 can move accurately along the traveling track 3.

[0035] Preferably, baffles are installed at both ends of the walking track 3, which can effectively prevent the front roller frame 4 from slipping off the walking track 3 during movement, thus improving the safety of the device.

[0036] The PLC controls the operation of the X-axis moving mechanism 201, the Z-axis moving mechanism 202, the two TIG welding torches 22, the four tilting motors 69, and the two drive motors 671.

[0037] In use, based on the length of the spiral coil cylinder 10, push the front roller frame 4 to move on the travel track 3 so that the distance between it and the end roller frame 4 is approximately the same as the cylinder length. Then tighten the knurled screws 68 so that they abut against the corresponding travel track 3, ensuring that the position of the front roller frame 4 is firmly locked. Start the two drive motors 671, which drive the gears 672 to rotate. The gears 672 mesh with the first rack 673 and the second rack 674 respectively, thereby causing the first convex plate 675 and the second convex plate 676 to move along the guide slide rod 677. The base plate 66 moves on the cover plate 63 as the first convex plate 675 and the second convex plate 676 move, thereby driving the support rollers 65 on both sides to move until the two corresponding support rollers 65 reach the position suitable for supporting the spiral coil cylinder 10. Place the spiral coil cylinder 10 on the support rollers 65 of the pair of roller frames 4. Finally, the flipping motor 69 is started, causing the spiral coil cylinder 10 to begin rotating slowly. At the same time, the welding mechanism 2 is started, and a pair of TIG welding torches 22 begin welding the coil on the cylinder.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the embodiments of the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
