Description

Technical Field

[0001] This utility model relates to the field of steel grating welding technology, and in particular to a steel grating welding device. Background Technology

[0002] Welding is one of the key processes in the production of steel grating. Steel grating is typically made by arranging and welding load-bearing flat steel bars and crossbars at certain intervals. Currently, existing methods of fixing steel grating before welding have many shortcomings.

[0003] Most fixing devices are ineffective at stably securing steel gratings of different sizes and specifications. In actual production, steel gratings come in a wide variety of sizes, and existing fixing devices cannot be flexibly adjusted according to the length and width of the steel gratings, leading to loosening and displacement of the steel gratings during the fixing process. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a steel grating welding device, the specific technical solution of which is as follows:

[0005] A steel grating welding device includes a working platform.

The first fixing components can be inserted into the first limiting member. Each first fixing component includes a first moving part and two sets of opposing first T-shaped clamps. The first moving part is used to drive the two sets of first T-shaped clamps to move towards or away from each other along the length direction of the working platform. At least two sets of second fixing components and a second limiting member located below the second fixing components are provided on the right side of the working platform. The second fixing components can be inserted into the second limiting member. Each second fixing component includes a second moving part and two sets of opposing second T-shaped clamps. The second moving part is used to drive the two sets of second T-shaped clamps to move towards or away from each other along the width direction of the working platform.

[0008] Preferably, the second moving part includes a second fixed shell, on which a fourth threaded rod is rotatably connected. Two sets of fourth nut blocks are symmetrically threaded onto the fourth threaded rod. One end of the second T-shaped clamp passes through the interior of the second fixed shell and connects to the fourth nut blocks. One end of the fourth threaded rod extends to the exterior of the second fixed shell and is connected to a second rotating handle.

[0010] The beneficial effects of this utility model are:

[0011] 1. By setting up a first fixing component and a second fixing component, the steel grating can be fixed in both the length and width directions, respectively.

[0018] 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 accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] Example

[0020] For steel grating welding equipment, please refer to [reference needed]. Figures 1-4 The steel grating welding device provided by this utility model mainly consists of a working platform 1, a first fixing component 2, a second fixing component 4, a first limiting component, and a second limiting component. Through the coordinated action of these components, the device can stably fix steel gratings 3 of different sizes, ensuring the smooth progress of the welding process.

[0021] The first fixing component 2 is located on the left side of the working platform 1, and there are at least two sets. Its main function is to fix and adjust the steel grating 3 in the length direction.

[0022] The first fixing component 2 includes a first fixing shell 21, which is the supporting structure of the entire component. The first fixing shell 21 is made of high-strength metal material, has good rigidity and stability, and can withstand the external forces generated during the welding process.

[0023] A third threaded rod 24 is rotatably connected to the first fixed housing 21. Both ends of the third threaded rod 24 are connected to the first fixed housing 21 via bearings to ensure its flexible rotation. The third threaded rod 24 is provided with two sets of threads with opposite directions. This design allows the third nut block 23, which is threaded to it, to move towards or away from each other when the third threaded rod 24 rotates.

[0024] Two sets of third nut blocks 23 are symmetrically threaded onto the third threaded rod 24. The inner sidewall of the third nut block 23 is adapted to the thread. When the third threaded rod 24 rotates, the two sets of third nut blocks 23 will move relative to each other along the axial direction of the third threaded rod 24.

[0025] One end of the first T-shaped clamping plate 22 extends through the interior of the first fixed shell 21 and connects with the third nut block 23. The movable part of the first T-shaped clamping plate 22 uses a clearance fit, ensuring that the first T-shaped clamping plate 22 can slide freely within the first fixed shell 21 while preventing excessive wobbling. The T-shaped structure of the first T-shaped clamping plate 22 allows for better contact with the edge of the steel grating 3, improving the stability of the fixation.

[0026] One end of the third threaded rod 24 extends to the outside of the first fixed shell 21 and is connected to the first rotary handle. By turning the first rotary handle, the operator can drive the third threaded rod 24 to rotate, thereby enabling the two sets of first T-shaped clamps 22 to move towards or away from each other along the length of the work platform 1, and thus fix and adjust the steel grating 3 in the length direction.

[0027] The first limiting component is located below the first fixing component 2 and is used to limit and adjust the position of the first fixing component 2 on the working platform 1 to adapt to the fixing requirements of steel gratings 3 of different lengths.

[0028] The working platform 1 is provided with a first slide groove 5 extending in the length direction. The first slide groove 5 is made with high-precision machining technology, and its inner surface is smooth, which can ensure that the first movable block 51 slides smoothly in it.

[0029] The first limiting component includes a first movable block 51 slidably connected in the first slide groove 5. The first movable block 51 and the first slide groove 5 are slidably fitted together, and the gap between them is precisely controlled to ensure the sliding flexibility of the first movable block 51 while preventing it from shaking during sliding.

[0030] A first nut block 52 is fixedly connected to the first slide groove 5. The first nut block 52 is firmly fixed to the first slide groove 5 by welding or bolting to ensure that it will not shift during operation.

[0031] A first threaded rod 53 is threadedly connected to the first nut block 52. One end of the first threaded rod 53 is rotatably connected to the first movable block 51. By rotating the first threaded rod 53, the first movable block 51 can move along its length in the first slide groove 5. The threaded fit between the first threaded rod 53 and the first nut block 52 has high precision, ensuring accurate adjustment.

[0032] The top of the first movable block 51 is provided with a first fixing hole 511, and the bottom of the first fixing shell 21 has a first limiting post that matches the first fixing hole 511. When the first fixing component 2 is installed on the first limiting component, the first limiting post is inserted into the first fixing hole 511, which plays a role in positioning and limiting, ensuring that the position of the first fixing component 2 on the working platform 1 is stable.

[0033] The second fixing component 4 is located on the right side of the working platform 1, and there are at least two sets of them. Its function is to fix and adjust the steel grating 3 in the width direction.

[0034] The second fixing component 4 includes a second fixing shell 41, which has a similar structure and function to the first fixing shell 21. It is made of high-strength metal material and provides support for the entire component.

[0035] A fourth threaded rod 44 is rotatably connected to the second fixed housing 41. Both ends of the fourth threaded rod 44 are connected to the second fixed housing 41 via bearings to ensure its rotational flexibility. The fourth threaded rod 44 has two sets of oppositely oriented threads, used to drive the fourth nut block 43 to move towards or away from each other.

[0036] Two sets of fourth nut blocks 43 are symmetrically threaded onto the fourth threaded rod 44. The inner sidewall of the fourth nut block 43 is adapted to the threaded rod 44. When the fourth threaded rod 44 rotates, the two sets of fourth nut blocks 43 will move relative to each other along the axial direction of the fourth threaded rod 44.

[0037] One end of the second T-shaped clamp 42 extends into the interior of the second fixing shell 41 and connects with the fourth nut block 43. The structure and connection method of the second T-shaped clamp 42 are similar to those of the first T-shaped clamp 22. Its T-shaped structure can better fit the edge of the steel grating 3 and improve the fixing effect.

[0038] One end of the fourth threaded rod 44 extends to the outside of the second fixed housing 41 and is connected to a second rotary handle. By turning the second rotary handle, the operator can drive the fourth threaded rod 44 to rotate, causing the two sets of second T-shaped clamps 42 to move towards or away from each other in the width direction of the working platform 1, thereby achieving the fixed adjustment of the steel grating 3 in the width direction.

[0039] The second limiting component is located below the second fixing component 4 and is used to limit and adjust the position of the second fixing component 4 on the working platform 1 to adapt to the fixing requirements of steel gratings 3 of different widths.

[0040] The work platform 1 is provided with a second slide groove 6 extending in the width direction. The machining accuracy and surface quality of the second slide groove 6 are the same as those of the first slide groove 5, ensuring that the second movable block 62 can slide smoothly in it.

[0041] The second limiting component includes a second movable block 62 that is slidably connected in the second slide groove 6. The second movable block 62 and the second slide groove 6 are in a sliding fit, with precise clearance control to ensure the flexibility and stability of its sliding.

[0042] A second nut block is fixedly connected to the second slide groove 6. The second nut block is firmly fixed to the second slide groove 6 by welding or bolting to prevent it from shifting during operation.

[0043] A second threaded rod is threadedly connected to the second nut block. One end of the second threaded rod is rotatably connected to the second movable block 62. By rotating the second threaded rod, the second movable block 62 can move along the width direction in the second slide groove 6. The threaded fit between the second threaded rod and the second nut block has high precision, ensuring accurate adjustment.

[0044] The second movable block 62 has a second fixing hole 611 at its top, and the second fixing shell 31 has a second limiting post at its bottom that matches the second fixing hole 611. When the second fixing component 4 is installed on the second limiting component, the second limiting post is inserted into the second fixing hole 611, which serves to position and limit the movement, ensuring that the second fixing component 4 is stable on the working platform 1.

[0045] When it is necessary to fix the steel grating 3, follow these steps:

[0046] Based on the length of the steel grating 3, first adjust the first fixing component 2. The operator turns the first handle, causing the third threaded rod 24 to rotate. Since the threads on the third threaded rod 24 are in opposite directions, the two sets of third nut blocks 23 will move towards or away from each other along the third threaded rod 24, thereby causing the two sets of first T-shaped clamps 22 to move towards or away from each other along the length of the work platform 1. This continues until the first T-shaped clamps 22 are in close contact with the edge of the steel grating 3, achieving initial fixation of the steel grating 3 in the length direction.

[0047] Next, adjust the second fixing component 4. Turn the second handle to rotate the fourth threaded rod 44. The threads on the fourth threaded rod 44 are in opposite directions, causing the two sets of fourth nut blocks 43 to move towards or away from each other along the fourth threaded rod 44, which in turn causes the two sets of second T-shaped clamps 42 to move towards or away from each other in the width direction of the working platform 1. This continues until the second T-shaped clamps 42 are tightly fitted to the edge of the steel grating 3, further fixing the steel grating 3 in the width direction.

[0048] If the position of the steel grating 3 is found to be inaccurate during the fixing process, the positions of the first movable block 51 and the second movable block 62 can be adjusted by rotating the first threaded rod 53 and the second threaded rod, respectively, thereby fine-tuning the positions of the first fixing component 2 and the second fixing component 4 to ensure that the steel grating 3 is in the optimal welding position.

[0049] After the steel grating 3 is fixed in place, welding can begin. Operators use appropriate welding equipment and follow the predetermined welding process to weld the steel grating 3. Because the steel grating 3 is stably fixed during the welding process, the welding quality is effectively guaranteed, resulting in uniform and strong welds, and reducing defects such as incomplete welds and missed welds.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
