Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, specifically to a welding equipment for preparing box-shaped components. Background Technology

[0002] Steel components are the main load-bearing framework in steel building structures, primarily composed of steel plates and various types of steel (angle steel, channel steel, I-beams, welded or hot-rolled H-beams) assembled with connectors. Box-type components, as an important form, have strong load-bearing capacity, but due to the large number of parts, they require extremely high positional accuracy and control during assembly and welding. Therefore, optimizing their manufacturing process is crucial to ensuring the overall structural quality.

[0003] For example, patent CN218135611U discloses a submerged arc welding device for an arc-shaped box-type component, including an arc-shaped box, a sliding seat on the arc-shaped box, and a support device on the sliding seat. The support device is used to support the sliding seat to slide on the arc-shaped box. The support device includes a telescopic rod disposed on the inner top of the sliding seat. The bottom end of the telescopic rod is connected to a rotating shaft. The free end of the rotating shaft is connected to and used to roll into contact with a universal wheel at the top of the arc-shaped box. Screws are installed on the sliding seats on both sides of the universal wheel. The screw threads pass through the sliding block and are used to push the sliding frame to move.

[0004] However, the existing equipment lacks sufficient adjustment flexibility in the welding mechanism, making it difficult to make quick and precise adjustments according to different welding positions and angles of the box-shaped components. This not only reduces welding efficiency but may also cause welding defects such as incomplete penetration and undercut due to improper welding angles. Furthermore, the clamping and fixing effect on the box-shaped components is poor, and the components are prone to displacement during the welding process, leading to welding position deviations and affecting welding quality. Utility Model Content

[0005] The purpose of this invention is to provide a welding device for the preparation of box-shaped components, in order to solve the problems mentioned in the background art, such as insufficient adjustment flexibility of the welding mechanism, difficulty in making quick and accurate adjustments according to different welding positions and angles of the box-shaped components, which not only reduces welding efficiency, but may also cause welding defects such as incomplete penetration and undercut due to improper welding angles. Furthermore, the clamping and fixing effect on the box-shaped components is not good, and the components are prone to displacement during the welding process, resulting in welding position deviation and affecting welding quality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a welding device for preparing box-shaped components, comprising a base, a first sliding groove formed in the middle of the top surface of the base, a first lead screw rotatably connected within the first sliding groove, a first motor fixedly connected to the right end of the first lead screw, the first motor being located in the middle of the right outer wall of the base, a first slider threadedly connected to both ends of the first lead screw, a movable plate fixedly connected to the top of the first slider, a fixing member fixedly connected to the front end of the top of the movable plate, a second motor fixedly connected to the right end of the fixing member, a gear fixedly connected to the output end of the second motor, support legs evenly fixedly connected to the top of the movable plate, a mounting ring fixedly connected to the top of the support legs, a toothed ring provided on the inner side of the mounting ring, the toothed ring meshing with the gear, and a welding component fixedly connected to the inner wall of the toothed ring.

[0007] Furthermore, guide grooves are provided on both sides of the top of the base, and guide rods are fixedly connected in the guide grooves. Guide blocks are fixedly connected on both sides of the bottom of the movable plate, and the base and the movable plate are slidably connected through the guide grooves and guide blocks.

[0008] Furthermore, annular grooves are provided on the inner wall of the mounting ring, and rotating rings are fixedly connected to both sides of the toothed ring. The mounting ring and the toothed ring are rotatably connected to the rotating rings through the annular grooves.

[0009] Furthermore, the outer wall of the mounting ring is uniformly provided with connectors, and the connectors are threaded with fixing bolts, and the mounting ring and the connectors are fixedly connected by the fixing bolts.

[0010] Furthermore, a support is fixedly connected to the top of the base, and a second sliding groove is provided in the middle of the top surface of the support. A double threaded rod is rotatably connected in the second sliding groove. A third motor is fixedly connected to the outer right wall of the support, and the output end of the third motor is fixedly connected to the double threaded rod. A second slider is threaded to both ends of the double threaded rod. A strip plate is fixedly connected to the top of the second slider. Telescopic rods are fixedly connected to both ends of the top of the strip plate. A placement plate is fixedly connected to the top of the telescopic rods.

[0011] Furthermore, a third sliding groove is provided on the top of the placement plate, and a second lead screw is rotatably installed in the third sliding groove. A handle is fixedly connected to the outer end of the second lead screw, and a third slider is threadedly connected to the second lead screw. A clamping plate is fixedly connected to the top of the third slider, and anti-slip protrusions are evenly fixedly connected to the inner wall of the clamping plate, and the anti-slip protrusions are hemispherical in shape.

[0012] Furthermore, scrapers are fixedly connected to both outer walls of the movable plate, chip removal grooves are provided on both sides of the top of the base, and collection boxes are fixedly connected to both sides of the bottom of the base, with the collection boxes located directly below the chip removal grooves.

[0013] Compared with the prior art, the beneficial effects of this utility model are: (1) The welding equipment for preparing box-shaped components uses the threaded transmission between the first lead screw and the first slider on the base to drive the moving plate to slide along the guide groove, thereby driving the installation ring and the welding parts to adjust horizontally, quickly adapting to different transverse welding positions of the box-shaped components, reducing component displacement steps, and improving welding preparation efficiency. The first motor drives the gear to rotate, and transmits power through the meshing of the gear and the gear ring. The gear ring rotates stably through the rotation ring and the annular groove of the installation ring, driving the welding parts to adjust at multiple angles, accurately aligning the welding interface, and avoiding welding quality defects. The connecting parts on the outer wall of the installation ring and the fixing bolt form a detachable structure. By loosening the fixing bolt, special welding parts for different welding scenarios can be quickly replaced, reducing adaptation costs and improving the equipment's versatility and flexibility.

[0014] (2) The welding equipment used for preparing box-shaped components has a second motor driving the double threaded rod in the second slide to rotate. The reverse threads at both ends drive the second sliders and strip plates on both sides to move closer or further away synchronously, adapting to box-shaped components of different widths. There is no need to replace the clamping components, which improves compatibility. The telescopic rod at the top of the strip plate can drive the placement plate and the component to move up and down, accurately aligning the welding height and avoiding trajectory deviation. The second screw on the placement plate is equipped with an operating handle. Manual rotation can drive the third slider and clamping plate to move towards each other, realizing longitudinal clamping of the component. The operation is convenient and the adjustment is accurate. The hemispherical anti-slip protrusions on the inner wall of the clamping plate increase the contact friction, resist welding vibration and thermal stress, prevent component displacement, strictly control welding deviation, and improve welding accuracy.

[0015] Furthermore, the scrapers fixed to the outer walls on both sides of the moving plate can scrape the welding waste on the base surface to the chip discharge grooves on both sides when the moving plate moves horizontally. The waste falls directly into the collection box below through the chip discharge grooves, eliminating the need for manual cleaning of the base, reducing the cleaning workload of operators, and preventing the accumulation of waste from affecting the transmission accuracy of the equipment.

Detailed Implementation

[0018] 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.

[0019] Example 1: A welding device for preparing box-shaped components uses a threaded connection between a first lead screw 11 and a first slider to adjust the horizontal position of the weldment 152, and a meshing connection between a gear 131 and a gear ring 151 to adjust the vertical angle of the weldment 152. This solves the problem of insufficient adjustment flexibility of the welding mechanism, which makes it difficult to quickly and accurately adjust according to different welding positions and angles of the box-shaped components. This not only reduces welding efficiency, but may also cause welding defects such as incomplete penetration and undercut due to improper welding angles.

[0020] like Figure 1 - Figure 5As shown, a welding device for preparing box-shaped components includes a base 1. A first groove is formed in the middle of the top surface of the base 1. A first lead screw 11 is rotatably connected in the first groove. A first motor is fixedly connected to the right end of the first lead screw 11, and the first motor is located in the middle of the right outer wall of the base 1. When the first motor is started, its output end can drive the first lead screw 11 to rotate. Both ends of the first lead screw 11 are threadedly connected to first sliders. A movable plate 12 is fixedly connected to the top of the first sliders. When the first lead screw 11 rotates, the first sliders at both ends slide towards or away from each other along the first groove, thereby driving the movable plate 12 to move horizontally. A fixing member 13 is fixedly connected to the front end of the top of the base 1. A second motor is fixedly connected to the right end of the fixing member 13. A gear 131 is fixedly connected to the output end of the second motor. Support legs 14 are evenly fixedly connected to the top of the moving plate 12. A mounting ring 15 is fixedly connected to the top of the support legs 14. A toothed ring 151 is provided on the inner side of the mounting ring 15, and the toothed ring 151 meshes with the gear 131. Starting the second motor can drive the gear 131 to rotate, thereby driving the toothed ring 151 to rotate. A welded part 152 is fixedly connected to the inner wall of the toothed ring 151. The angle of the welded part 152 can be adjusted when the toothed ring 151 rotates. Both sides of the top of the base 1 are open. A guide groove is provided, and a guide rod is fixedly connected inside the guide groove. Guide blocks are fixedly connected to both sides of the bottom of the movable plate 12, and the base 1 and the movable plate 12 are slidably connected to the guide blocks through the guide groove. This structure is used to ensure the stability of the horizontal movement of the movable plate 12. Annular grooves are provided on the inner wall of the mounting ring 15. Rotating rings are fixedly connected to both sides of the toothed ring 151, and the mounting ring 15 and the toothed ring 151 are rotatably connected to the rotating rings through the annular grooves, ensuring that the toothed ring 151 can stably rotate around the center of the mounting ring 15. Connecting parts 16 are evenly arranged on the outer wall of the mounting ring 15, and fixing bolts 161 are threadedly connected to the connecting parts 16. Ring 15 and toothed ring 151 are fixedly connected by fixing bolt 161. Loosening fixing bolt 161 can release the fixing restriction of connecting piece 16 on toothed ring 151 and welded part 152, making it easy to replace welded part 152. Scrapers 121 are fixedly connected to both outer walls of the moving plate 12. During the movement of the moving plate 12, scraper 121 can scrape the welding waste scattered on the surface of base 1 to both sides. Chip discharge grooves are opened on both sides of the top of base 1. Collection boxes 3 are fixedly connected to both sides of the bottom of base 1, and collection boxes 3 are located directly below chip discharge grooves. Waste pushed into chip discharge grooves by scraper 121 can fall into collection box 3, realizing automatic collection.

[0021] Example 2: Unlike Example 1, the distance between the two clamping plates 251 is adjusted by the threaded connection between the double threaded rod 21 and the second slider, the height of the clamping plate 251 is adjusted by the telescopic rod 23, and the position of the clamping plate 251 is limited by the threaded connection between the second lead screw 25 and the third slider. This solves the problems of poor clamping and fixing effect on box-shaped components, easy displacement of components during welding, resulting in welding position deviation and affecting welding quality.

[0022] like Figure 6 - Figure 7 As shown, a support 2 is fixedly connected to the top of the base 1. A second sliding groove is provided in the middle of the top surface of the support 2. A double threaded rod 21 is rotatably connected in the second sliding groove. A third motor is fixedly connected to the outer right wall of the support 2, and the output end of the third motor is fixedly connected to the double threaded rod 21. When the third motor is started, its output end drives the double threaded rod 21 to rotate. Both ends of the double threaded rod 21 are threadedly connected to second sliders. Because the threads at both ends of the double threaded rod 21 are in opposite directions, the two second sliders connected by the threads will move closer or further away along the second sliding groove. A strip plate 22 is fixedly connected to the top of the second slider, thereby driving the top strip plate 22 and the components above to move. The spacing of the clamping structures on both sides can be adjusted according to the width of the box-shaped component to achieve the adaptation of components of different widths. Telescopic rods 23 are fixedly connected to both ends of the top of the strip plate 22. A placement plate 24 is fixedly connected to the top of the telescopic rods 23. The telescopic rods 23 at both ends of the top of the strip plate 22 can freely extend and retract, pushing the placement plate 24 to move up and down. By controlling the extension and retraction of the telescopic rods 23, the... The height of the box-shaped component on the placement plate 24 is precisely adjusted to ensure that the position of the component to be welded is aligned with the height of the welding part 152 inside the mounting ring 15, avoiding deviation of the welding trajectory due to height discrepancy. A third sliding groove is provided on the top of the placement plate 24, and a second lead screw 25 is rotatably mounted on the third sliding groove. A handle is fixedly connected to the outer end of the second lead screw 25, and a third slider is threaded onto the second lead screw 25. A clamping plate 251 is fixedly connected to the top of the third slider. The operator rotates the outer end of the second lead screw 25 on the placement plate 24... The handle drives the second lead screw 25 to rotate within the third slide groove. The third slider, which is threadedly connected to the second lead screw 25, causes the top clamping plate 251 to move towards each other along the third slide groove until the clamping plate 251 fits against the outer wall of the box-shaped component. Anti-slip protrusions are evenly fixedly connected to the inner wall of the clamping plate 251, and the anti-slip protrusions are hemispherical in shape. The hemispherical anti-slip protrusions on the inner wall of the clamping plate 251 can increase the friction with the surface of the component, effectively resist welding vibration and thermal stress, prevent the component from shifting during the welding process, and achieve stable clamping.
