Technical Field
[0001] This utility model relates to the field of steel production and processing technology, specifically a steel welding seam grinding device. Background Technology
[0002] Steel can be classified into four main categories according to its shape: profiles, plates, pipes, and wires, covering different structural forms to adapt to various processing needs. Profiles include angle steel and channel steel, plates are flat, pipes are hollow cylinders, and wires are thin round steel wires, each corresponding to different forming and application scenarios.
[0003] Steel plate welding is a process that uses high-temperature melting of the base material and filler metal to form a weld, firmly connecting two steel plates. The weld is the core part of the connection, and its quality directly determines the strength and stability of the welded structure. After welding, the weld and surrounding area need to be ground with hand-held grinding tools to remove weld slag, burrs and excess weld metal. This not only improves the smoothness of the appearance, but also reduces stress concentration and ensures the performance of the welded parts.
[0004] After welding, the existing steel plates need to be ground. However, it was found that after grinding, it is necessary to visually determine whether the weld reinforcement has been ground flat, which reduces the grinding speed.
[0005] Therefore, a steel welding seam grinding device is proposed to address the above problems. Utility Model Content

[0010] Preferably, a round rod is fixed to the side wall of the bolt; multiple round rods are provided on the bolt; by adding multiple round rods, the bolt can be rotated quickly by increasing the thrust of the round rods when the bolt rotates, thereby speeding up the fixing of the bolt to the slide rod.
[0011] Preferably, a counterweight is slidably fitted in the middle of the handle; multiple counterweights are provided on the handle; by adding counterweights, the corresponding counterweights can be added according to the resistance when the detection plate moves down, thereby accelerating the downward movement speed of the detection plate after placement and reducing the downward resistance of the slide bar.

[0023] 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 scope of protection of the present utility model.
[0024] Specific implementation examples are given below.
[0025] like Figures 1 to 5As shown in the figure, a steel welding seam grinding device according to an embodiment of the present invention includes a base 1, a placement platform 11 fixedly connected to the middle of the base 1; a plurality of vacuum suction cups 12 fixedly connected to the middle of the placement platform 11; a connecting pipe 13 fixedly connected to the side wall of the placement platform 11; the connecting pipe 13 and the vacuum suction cups 12 are in communication; a steel plate 14 is provided on the top of the placement platform 11; a handheld grinder 15 is provided on the top of the steel plate 14; a slider 16 is slidably connected to the surface of the base 1; and a top of the slider 16 is provided with... An adjustment component 17 is provided; a handle 19 is fixedly connected to the top of the adjustment component 17; a detection plate 101 is connected to the side wall of the adjustment component 17 via a bending component 102; during operation, the steel plate 14 is first placed on the top of the placement platform 11, and then the connecting pipe 13 is connected to the air pump to evacuate air through the connecting pipe 13. Subsequently, the air inside the vacuum suction cup 12 will be gradually discharged, thus creating a negative pressure, thereby adsorbing and fixing the steel plate 14. After fixing, the weld on the steel plate 14 is polished by a handheld grinder 15. After the seam is polished, when it is necessary to check the flatness after polishing, first unlock the detection plate 101 by adjusting component 17, then pull the handle 19 to raise the detection plate 101, and at the same time pull the slider 16 by the handle 19 to move the detection plate 101 to the top of the steel plate 14. After it reaches the top of the steel plate 14, move the handle 19 down to move the detection plate 101 down to contact the steel plate 14. At this time, lock the detection plate 101 by adjusting component 17, and then slide the detection plate 101 on the surface of the steel plate 14 by pulling the handle 19. If the sliding is blocked, it means that there is still a protrusion in the weld in this area, so the area can be reworked. When the inspection plate 101 can move on the surface of the steel plate 14 without being blocked, it means that the weld has been ground flat. By adding the inspection plate 101, the flatness of the weld can be detected by sliding the inspection plate 101 after the steel plate 14 is ground. Thus, the processing status of the weld of the steel plate 14 can be quickly reflected by sliding, which speeds up the inspection speed of the weld after the steel plate 14 is ground, thereby speeding up the weld processing of the steel plate 14.
[0026] like Figures 1 to 4 As shown, the adjustment assembly 17 includes a slide rod 2; the slide rod 2 and the slider 16 are slidably connected; a bolt 21 is threadedly connected to the side wall of the slider 16; the bolt 21 and the slider 16 are in contact; during operation, when adjusting the detection plate 101, the bolt 21 can be rotated first. When the bolt 21 rotates, it will gradually move away from the surface of the slide rod 2, at which point the slide rod 2 will be unlocked. After unlocking, the slide rod 2 can be raised and lowered, thereby raising and lowering the metal of the detection plate 101, and thus adjusting the position of the detection plate 101 according to the thickness of the steel plate 14; by increasing the adjustment means of the detection plate 101, the detection plate 101 can be raised and lowered by adjusting the bolt 21 and the slide rod 2 when the steel plate 14 is replaced, thereby adapting to steel plates 14 of various thicknesses, thus increasing convenience when inspecting the steel plate 14.
[0027] like Figures 1 to 5 As shown, a protective plate 3 is fixed to the top of the detection plate 101; the top of the protective plate 3 is sloped; during operation, when the steel plate 14 is being polished, debris will be scattered around. When the debris falls onto the top of the detection plate 101, it will come into contact with the protective plate 3 and then move to both sides along the surface of the protective plate 3, thus leaving the top of the detection plate 101; by adding the protective plate 3, the debris can be guided by the protective plate 3 when it falls, thereby reducing the amount of debris staying on the top of the detection plate 101 and accelerating the falling of the debris.
[0028] like Figure 4 As shown, a round rod 4 is fixed to the side wall of the bolt 21; multiple round rods 4 are provided on the bolt 21; during operation, when the bolt 21 is rotated, the round rod 4 increases the force-bearing area, so that each rotation increases the force-bearing points of the bolt 21 during rotation through multiple round rods 4, thereby speeding up the rotation speed of the bolt 21; by adding multiple round rods 4, the bolt 21 can be rotated quickly by increasing the thrust of the round rods 4 during rotation, thereby speeding up the fixing of the bolt 21 to the slide rod 2.
[0029] like Figures 4 to 5 As shown, a counterweight 5 is slidably fitted in the middle of the handle 19; multiple counterweights 5 are set on the handle 19; during operation, after the handle 19 is released, the detection plate 101 will move down by itself. At this time, the corresponding counterweight 5 can be inserted into the middle of the handle 19, so that the slide rod 2 increases its own weight. At this time, it will be easier to move the handle 19 down by gravity; by adding counterweights 5, the corresponding counterweights 5 can be added according to the resistance when the detection plate 101 moves down, thereby speeding up the downward movement of the detection plate 101 after placement and reducing the downward resistance of the slide rod 2.
[0030] like Figures 4 to 5 As shown, the bending assembly 102 includes a connecting plate 6; the connecting plate 6 is rotatably connected to the slide rod 2; during operation, when the detection plate 101 encounters an obstruction while moving on the surface of the steel plate 14, the detection plate 101 will be blocked, and at the same time, when the slider 16 moves, the detection plate 101 will rotate through the connecting plate 6 due to the obstruction, thereby making it easier to intuitively judge the flatness of the weld on the surface of the steel plate 14; by adding the connecting plate 6, the detection plate 101 can be bent under force when moving, thereby increasing the feedback on the weld detection and increasing the intuitive judgment during detection.
[0031] Working principle: First, place the steel plate 14 on top of the placement platform 11. Then, connect the connecting pipe 13 to the air pump to evacuate air. The air inside the vacuum suction cup 12 will gradually be expelled, creating a negative pressure that adsorbs and fixes the steel plate 14. After fixing, use a handheld grinder 15 to grind the weld seams on the steel plate 14. When flatness needs to be checked after grinding, first unlock the detection plate 101 using the adjustment component 17. Then, pull the handle 19 to raise the detection plate 101. Simultaneously, pull the slider 16 using the handle 19 to move the detection plate 101. The plate 101 is moved to the top of the steel plate 14. After reaching the top of the steel plate 14, the handle 19 is moved down to move the inspection plate 101 down and make contact with the steel plate 14. At this time, the inspection plate 101 is locked by the adjusting component 17. Then, the inspection plate 101 is pulled by the handle 19 to slide on the surface of the steel plate 14. When the sliding is blocked, it means that there is still a protrusion in the weld in this area, so the area can be reworked. When the inspection plate 101 can move on the surface of the steel plate 14 without being blocked, it means that the weld has been ground smooth. When adjusting the inspection plate 101, the bolt 21 can be rotated first. When the bolt 21 is rotated... When the bolt 21 rotates, it gradually moves away from the surface of the slide bar 2, at which point the slide bar 2 is unlocked. After unlocking, the slide bar 2 can be raised and lowered, thereby raising and lowering the metal of the detection plate 101 and adjusting the position of the detection plate 101 according to the thickness of the steel plate 14. When the steel plate 14 is polished, debris will be scattered around. When the debris falls onto the top of the detection plate 101, it will contact the protective plate 3 and then move to both sides along the surface of the protective plate 3, thus leaving the top of the detection plate 101. When the bolt 21 is rotated, the round rod 4 increases the force-bearing area, so that with each rotation, the force is increased through multiple round rods 4. Adding a force point to the bolt 21 during rotation increases the rotation speed of the bolt 21. After releasing the handle 19, the detection plate 101 will move down by itself. At this time, the corresponding counterweight 5 can be inserted into the middle of the handle 19 to increase the weight of the slide rod 2. This will make it easier to move the handle 19 down by gravity. When the detection plate 101 encounters an obstruction while moving on the surface of the steel plate 14, the detection plate 101 will be blocked. At the same time, when the slider 16 moves, the detection plate 101 will rotate through the connecting plate 6 due to the obstruction. This allows for a more intuitive judgment of the flatness of the weld seam on the surface of the steel plate 14.
[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
