Description

Technical Field

[0001] This utility model relates to the field of welding equipment, and in particular to a welding equipment for metal frame production. Background Technology

[0002] A metal shelf is a support structure made of metal materials (such as steel and aluminum), characterized by its sturdiness, durability, and strong load-bearing capacity. It typically consists of multiple metal components connected and fixed together, used to support or store items. Metal shelves are constructed by welding multiple metal plates and components together, thus requiring a welding device in the production process.

[0003] A search revealed that the Chinese patent "A Metal Bracket Welding Platform" (authorization announcement number CN221676299U) utilizes two cylinders to facilitate the adjustment of the positions of the first and second limiting components. This allows workers to make adjustments based on the length of the metal rods, preventing distance between the two rods from affecting the welding process. Furthermore, the third bearing seat, in conjunction with the rotating shaft, assists in the rotation of the second limiting component, enabling workers to adjust the angle at the joint between the two components based on the cross-section of the metal rods.

[0004] Although the above application can assist the second limiting component in rotating by cooperating with the third bearing seat and the rotating shaft, allowing the staff to adjust the angle of the splice, the metal frame often requires multi-directional welding at the connection of the two metal rods during the welding process. This device can only allow the two metal rods to adjust the angle on the same horizontal plane, which has certain limitations in use.

[0005] Therefore, a welding device for metal frame production is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a welding device for metal frame production to solve the above problems, thereby improving the limitation that the angle of a welding point can only be adjusted at the same horizontal level.

[0007] This utility model achieves the above-mentioned objective through the following technical solution: a welding device for metal frame production, comprising: a box body, a worm gear disposed on the surface of the box body, and a worm engaging on the surface of the worm gear;

[0008] The adjustment mechanism includes a first rotating frame and a second rotating frame rotatably connected to the housing. The first rotating frame and the second rotating frame are fixedly connected to two slide rails. The inner wall of the slide rail is provided with a slide groove. The inner wall of the slide groove is slidably connected to two first sliders and one second slider. The inner wall of the second slider is rotatably connected to a connecting block. The top of the connecting block is slidably connected to a clamping block. The inner wall of the housing is fixedly connected to a fixing plate.

[0009] Preferably, the end of the first rotating frame away from the second rotating frame extends through the housing and is fixedly connected to the worm gear, while the end of the second rotating frame away from the first rotating frame is rotatably connected to the inner wall of the housing. This allows the adjustment mechanism to rotate, enabling welding at different angles for the same weld point.

[0010] Preferably, a common slide rod is fixedly connected between the two first sliders aligned with the slide rails. A connecting block is slidably connected to the surface of the slide rod, and a clamping block is rotatably connected to the top of the connecting block. The connecting block and the clamping block rotate simultaneously, allowing for more complete angle adjustment.

[0011] Preferably, a threaded rod is threadedly connected to the top of the clamping block, a pressure block is rotatably connected to the bottom of the threaded rod, and a handle is fixedly connected to the top of the threaded rod. This provides greater stability for the steel rod within the clamping block.

[0012] Preferably, the second slider within the slide rail is positioned between the two first sliders, and both the first and second sliders are rectangular blocks. This prevents the slider from falling off while sliding within the slide rail.

[0013] Preferably, the clamping blocks have a "C"-shaped cross-section, and the four clamping blocks are arranged in pairs opposite each other. This facilitates the fixing of the steel rod.

[0014] Preferably, the fixing plate is inclined, and its size matches the inner wall of the box. This facilitates the collection of welding slag that falls during the welding process.

[0015] The beneficial effects of the utility model are:

[0016] By setting up a first rotating frame and a second rotating frame to rotate and connect to the box, when it is necessary to weld two metal rods, the adjustment mechanism can be rotated to perform multi-angle welding at the connection point, making the welding process more convenient. It is not only possible to weld two metal rods on one plane, but also to make welding more convenient for workers and make the weld point more stable, reducing the limitations during welding.

[0017] By setting the first slider to slide in conjunction with the second slider to slide within the slide rail, this device can be applied to steel rods of different lengths. By setting the second slider to slide in conjunction with the slide rail and allowing the clamp to rotate, the angle between the two steel rods can be adjusted more flexibly.

[0018] By installing an inclined fixing plate inside the box, welding slag that falls during welding can be collected, making cleaning easier. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] When implementing: Figure 1-4 As shown, a welding device for metal frame production includes: a housing 100, a worm gear 201 disposed on the surface of the housing 100, and a worm 200 meshing with the surface of the worm gear 201;

[0026] The adjustment mechanism 300 includes a first rotating frame 310 and a second rotating frame 311 rotatably connected to the housing 100. The first rotating frame 310 and the second rotating frame 311 are fixedly connected to two slide rails 320. The inner wall of the slide rail 320 is provided with a slide groove 321. The inner wall of the slide groove 321 is slidably connected to two first sliders 322 and a second slider 323. The inner wall of the second slider 323 is rotatably connected to a connecting block 350. The top of the connecting block 350 is slidably connected to a clamping block 330. The inner wall of the housing 100 is fixedly connected to a fixing plate 110.

[0027] like Figure 2 , Figure 3 and Figure 4 As shown, the end of the first rotating frame 310 away from the second rotating frame 311 extends through the housing 100 and is fixedly connected to the worm gear 201. The end of the second rotating frame 311 away from the first rotating frame 310 is rotatably connected to the inner wall of the housing 100. The same slide rod 340 is fixedly connected between the first sliders 322 of the two slide rails 320 that are aligned with each other. A connecting block 350 is slidably connected to the surface of the slide rod 340. A clamping block 330 is rotatably connected to the top of the connecting block 350. A threaded rod 332 is threadedly connected to the top of the clamping block 330. A pressure block 331 is rotatably connected to the bottom of the threaded rod 332. A handle is fixedly connected to the top of the threaded rod 332.

[0028] In this embodiment, when the worm gear 200 is rotated, the worm gear 200 drives the worm wheel 201 to rotate, thereby driving the first rotating frame 310 to rotate. Since the first rotating frame 310 and the second rotating frame 311 are fixed on the same slide rail 320, and the two slide rails 320 are supported by a slide rod 340, the second rotating frame 311 will rotate along with the first rotating frame 310, thereby causing the entire adjusting mechanism 300 to rotate. Both ends of the two slide rails 320 are closed, and the first slider 322 and the second slider 323 will not fall off when sliding in the slide groove 321. When the handle is rotated, the handle will drive the threaded rod 332 to rotate. Since the threaded rod 332 is threadedly connected to the top of the clamping block 330, it will move downwards while rotating, driving the pressure block 331 to fix the steel rod.

[0029] like Figure 1 , Figure 3 and Figure 4 As shown, the second slider 323 inside the slide rail 320 is positioned between the two first sliders 322, and both the first sliders 322 and the second slider 323 are rectangular blocks. The clamping blocks 330 have a "C"-shaped cross-section, and the four clamping blocks 330 are arranged in pairs opposite each other.

[0030] The cross-section of the slide groove 321 is T-shaped. The first slider 322 and the second slider 323 are square-shaped, which makes it difficult for the two sliders to fall off while sliding in the slide groove 321. At the same time, the slide rod 340 and the connecting block 350 can also be set.

[0031] The fixing plate 110 is inclined, and its size matches the inner wall of the box 100. When welding slag falls into the box 100 during the welding process, it will slide down the inclined surface of the fixing block to the angle between the box 100 and the fixing block. A collection device can be installed at this point to clean the welding slag inside the box 100.

[0032] When using this utility model, first, stabilize the fixing mechanism in a horizontal state, then place the steel rod to be welded into the clamping block 330 on the slide bar 340, then align it with the pressure block 331 above, then turn the handle to make the threaded rod 332 move downward. The threaded rod 332 drives the pressure block 331 to squeeze the steel rod, so that the steel rod is fixed in the clamping block 330. Then select a second steel rod and place it in the clamping block 330 connected to the second slider 323. Repeat the above operation to complete the fixing of the steel rod.

[0033] Before starting welding, move the clamp 330 on the slide bar 340 laterally on the slide bar 340 to select a suitable position, and then slide the second slider 323. The second slider 323 slides in the groove 321 to weld the two steel rods together.

[0034] When the angle of the two steel rods needs to be adjusted, the appropriate angle can be selected by rotating the clamping block 330 on the slide bar 340. Then, while rotating the clamping block 330 on the second slide bar 323, the connecting block 350 on the second slide bar 323 can also be rotated for fine adjustment to align the two slide bars for welding. After the two steel rods are initially welded and fixed, a third steel rod is selected for welding, and the above operation is repeated to complete the welding of the subsequent basic frame. When the basic frame welding is completed, if the weld points at the connection between each pair of steel rods need to be welded at multiple angles, the worm gear 200 is rotated, which drives the worm wheel 201 to rotate, and the worm wheel 201 drives the first rotating frame 3. While rotating 10, the adjusting mechanism 300 rotates as a whole. After selecting a suitable angle, the worm gear 200 is stopped from rotating to keep the adjusting mechanism 300 stable. Then, welding is performed at different angles for each weld point to make the welding between each pair of steel rods more stable. After welding is completed, the handle on each clamping block 330 is rotated to move the threaded rod 332 upwards, driving the pressure block 331. Then, the connecting block 350 on the second slider 323 is rotated to adjust the angle, and the welded frame can be removed. The welding slag generated during the welding process will fall onto the fixing plate 110 inside the box 100 and be collected along the inclined surface of the fixing plate 110 into the box 100 for easy subsequent cleaning.

[0035] When the lead angle of the worm 200 is less than the equivalent friction angle between the meshing gear teeth, the mechanism has self-locking properties and can achieve reverse self-locking, meaning that only the worm 200 can drive the worm wheel 201, and the worm wheel 201 cannot drive the worm 200. For example, in lifting machinery, the reverse self-locking property of the self-locking worm 200 mechanism can provide safety protection. "When the worm wheel 201 is the driving member, and the lead angle of the worm 200 and worm wheel 201 mechanism is less than the friction angle, the mechanism will exhibit self-locking." / Reference: *China New Technologies & New Products*, 2016, No. 14, p. 43.

[0036] It should be noted that the threaded rod 332, worm gear 201 and worm 200 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs, and will not be elaborated here.

[0037] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
