Description

Technical Field

[0001] This utility model relates to the field of shelf welding technology, and more specifically, it relates to an electrode head angle adjustment mechanism for a spot welding machine. Background Technology

[0002] In the fields of warehousing and logistics equipment manufacturing, automated rack production, and heavy steel structure processing, the welding quality of rack components, such as L-shaped components, uprights, supports, and plates, directly affects the load-bearing capacity and service life of the racks. In existing rack welding processes, spot welding machines are key equipment; however, their electrode head angle adjustment mechanisms suffer from the following two types of technical defects, which restrict welding efficiency and finished product quality.

[0003] Currently, welding equipment on the market has several limitations. First, it lacks adaptability to welding asymmetrical structures of shelving components. Shelving components typically have L-shaped, T-shaped, or irregular cross-sections, and their welding joints are mostly spatial three-dimensional connections, such as the vertical connection between beams and uprights. Traditional spot welding machines often have electrodes with fixed angles or only support limited directional adjustment, making it difficult to dynamically adjust the welding angle according to the geometric characteristics of the shelving components.

[0004] Secondly, interference can occur when the welding section flips or switches between multiple workstations with rack components or equipment housings. To meet the multi-sided welding requirements of racks, existing equipment typically uses rotary or flip welding arm structures, but the electrode head angle adjustment range is limited. When the welding section needs to flip from one side of the rack to the other, such as switching from the upper surface of a beam to the lower surface, its movement trajectory is prone to mechanical collision with the rack components themselves, such as adjacent support rods or equipment housings, leading to welding interruptions, workpiece scratches, or equipment malfunctions. Utility Model Content

[0015] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0016] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0017] Please see Figure 1-6 The present invention provides the following technical solution: Example 1 addresses the following two problems: first, the difficulty of targeted welding of the welding part 44 at the joint between the L-shaped component 11 and the plate 12 during the welding process; and second, the problem of interference between the welding part 44 and the housing 1 after the welding part 44 is flipped over.

[0018] The device includes a housing 1, a material rack 2 disposed beside the housing 1, and a material plate 3 slidably disposed on top of the material rack 2 for supporting the workpiece to be welded. The electrode head angle adjustment mechanism also includes an adjustment mechanism 4. The adjustment mechanism 4 is disposed beside the housing 1. The adjustment mechanism 4 includes a clamping part 41, a first horizontal sliding part 42, a rotating part 43, and a welding part 44. The clamping part 41 has multiple parts and is disposed on top of the material plate 3, and all clamping parts 41 are used to clamp the workpiece to be welded. The first horizontal sliding part 42 is slidably disposed beside the housing 1 and is located on top of the material rack 2. The rotating part 43 is disposed beside the first horizontal sliding part 42. The welding part 44 is disposed beside the rotating part 43, and when the rotating part 43 rotates, it can drive the welding part 44 to rotate synchronously.

[0019] In this embodiment, the workpiece is a component of a shelf assembly, which includes an L-shaped member 11 and a plate 12, together forming a shelf for placing goods. In this embodiment, the rotating part 43 is preferably a rotary cylinder, which drives the welding part 44 to rotate when it rotates. First, the plate 12 to be welded is placed on top of the placement plate 3, and then the clamping part 41 clamps the L-shaped member 11 and the plate 12 to be welded. In this embodiment, the top of the placement plate 3 is provided with multiple cylinders for driving the clamping part 41 to move, and the multiple cylinders are preferably electric cylinders. Then, the operator places the L-shaped member 11 to be welded at the four corners of the plate 12 and ensures that it is in contact. Next, the welding part 44 moves towards the placement plate 3 under the drive of the first horizontal sliding part 42. Then, the rotating part 43 starts to rotate, driving the welding part 44 to rotate synchronously, so that the welding part 44 is located at an inclined angle next to the L-shaped member 11 to be welded. The problem of difficulty in welding the L-shaped component 11 and the plate 12 to be welded has been solved, and efficient and targeted welding between the L-shaped component 11 and the plate 12 has been achieved without causing interference between the welding part 44 and the housing 1 after the welding part 44 is flipped over.

[0020] See Figures 1-3 The adjustment mechanism 4 also includes a connecting frame 45, a first horizontal limiting part 46, a first vertical guide rail 47, and a first vertical sliding part 48. The connecting frame 45 is slidably disposed on the side of the housing 1. The first horizontal limiting part 46 is disposed on the side of the connecting frame 45 and is used to limit the first horizontal sliding part 42 from moving. The first vertical guide rail 47 is disposed on the side of the housing 1. The first vertical sliding part 48 is slidably disposed on the first vertical guide rail 47 and is fixedly connected to the connecting frame 45. When the first vertical sliding part 48 moves, it can drive the connecting frame 45 to move synchronously.

[0021] To drive the welding part 44 to move closer to the material placement plate 3 and to move the welding part 44 up and down, the first horizontal sliding part 42 can first move closer to the material placement plate 3 under the restriction of the first horizontal limiting part 46. In order to make the welding part 44 descend to perform welding work, when the first vertical sliding part 48 slides on the first vertical guide rail 47, the first vertical sliding part 48 can drive the connecting frame 45, the first horizontal sliding part 42 and the first horizontal limiting part 46 to move upward synchronously.

[0022] See Figures 1-3 The adjustment mechanism 4 also includes a positioning part 49, a sliding rod 491, and a telescopic spring 492. The positioning part 49 is located on the top of the first horizontal sliding part 42 and is located above the welding part 44. The sliding rod 491 has a pair and is slidably disposed on the top of the positioning part 49, and the bottom of the pair of sliding parts is located above the welding part 44. The telescopic spring 492 has a pair and is respectively sleeved on the outside of the sliding rod 491. When the welding part 44 is flipped, it can contact the end face of the sliding rod 491 and drive the telescopic spring 492 to be in a compressed state.

[0023] To reduce the shaking amplitude of the welding part 44 after flipping and ensure welding accuracy, the problem of shaking that easily occurs after the welding part 44 stops flipping is addressed. After the welding part 44 completes the flipping action, the end of the welding part 44 comes into contact with the end face of the sliding rod 491. At this time, the sliding rod 491 is compressed and undergoes elastic deformation, entering a compressed state. Through elastic buffering, it absorbs the impact energy of the welding part 44, thereby effectively suppressing the problem of decreased welding accuracy caused by the accumulation of shaking during long-term flipping of the welding part 44.

[0024] See Figures 2-5 The adjustment mechanism 4 also includes a first telescopic cylinder 493 and a second telescopic cylinder 494; the first telescopic cylinder 493 is disposed on the side of the housing 1, and the output end of the first telescopic cylinder 493 is connected to the first vertical sliding part 48. When the first telescopic cylinder 493 is driven, it can drive the first vertical sliding part 48 and the connecting frame 45 to move synchronously; the second telescopic cylinder 494 is disposed on the side of the connecting frame 45, and the output end of the second telescopic cylinder 494 is connected to the first horizontal sliding part 42.

[0025] When the first telescopic cylinder 493 is activated, it can drive the first vertical sliding part 48 to move along the first horizontal limiting part 46. When the second telescopic cylinder 494 is activated, it can drive the connecting frame 45, the first horizontal sliding part 42, the first horizontal limiting part 46 and the welding part 44 to move synchronously.

[0026] See Figures 2-4The adjustment mechanism 4 also includes an electric push rod 495 and a connecting part 496. The electric push rod 495 is located at the bottom of the housing 1 and is located next to the material plate 3. The output end of the electric push rod 495 is connected to the material plate 3. When the electric push rod 495 is started, it can drive the material plate 3 to move towards the welding part 44.

[0027] When the electric push rod 495 is started, it can drive the material plate 3 and the clamped L-shaped structure and plate 12 to move up or down, thereby enabling the clamped L-shaped component 11 and plate 12 to rise and cooperate with the descending welding part 44 to perform welding work, which can further improve the welding accuracy.

[0028] See Figure 5 The adjustment mechanism 4 also includes a first linear driver 497, a lead screw 498, and a stroke section 499; the first linear driver 497 is disposed on the top of the material rack 2; the lead screw 498 is disposed at the output end of the first linear driver 497, and the lead screw 498 is threadedly connected to the material rack 3; the stroke section 499 is disposed on the top of the material rack 2, and a horizontal groove for limiting the sliding of the material rack 3 is provided on the top of the stroke section 499.

[0029] In this embodiment, the welding part 44 only welds two of the L-shaped components 11 and the plate 12, while the L-shaped components 11 and the plate 12 on the side away from the welding part 44 are welded manually. Similarly, the operator can also release the clamping part 41 after welding to clamp the unwelded parts and automatically weld them through the welding part 44 in the adjustment mechanism 4.

[0030] Obviously, the embodiments described above 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 should fall within the protection scope of this utility model.
