Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, and in particular to a tooling and fixture for producing steel grating. Background Technology

[0002] The tooling and fixtures used in the production of steel gratings mainly address the production needs of steel gratings. Steel gratings, also known as steel grids, are steel products made by arranging flat steel bars at certain intervals and crossbars and welding them together to form a grid with square openings. They are primarily used for trench covers, steel structure platform panels, and steel stair treads. During production, precise welding of the steel gratings is required to ensure structural stability and load-bearing capacity. Existing tooling and fixtures for steel grating welding have relatively fixed structures and are generally only suitable for fixing one type of steel grating structure. This prevents the tooling and fixtures from flexibly adapting to changes in the steel grating structure, thus affecting production efficiency and product quality. The background technology for producing tooling and fixtures for steel gratings mainly focuses on improving and optimizing existing tooling and fixtures to meet the diverse needs of steel grating production and improve production efficiency.

[0003] Steel grating is widely used in industrial platforms, stair treads, and drainage ditch covers. During the production process, steel grating requires precise welding to ensure its structural stability and load-bearing capacity. Most existing tooling fixtures are usually fixed in structure and can only be used for steel gratings of specific sizes or structures, which limits the flexibility and efficiency of production. Therefore, we propose a tooling fixture for producing steel grating to solve this problem. Utility Model Content

[0004] The purpose of this utility model is to provide a tooling fixture for producing steel gratings, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A tooling fixture for producing steel grating includes: a base plate, two mounting blocks slidably mounted on both sides of the base plate, a threaded rod rotatably mounted between the two mounting blocks on the same side, two clamping blocks threadedly connected to the threaded rod, and two threaded grooves with opposite directions of rotation on the threaded rod; a fixing block fixedly mounted on the base plate, a rotating rod rotatably mounted inside the fixing block; a mounting plate fixedly mounted on the base plate, a motor fixedly mounted on the mounting plate, the output end of the motor fixedly connected to the rotating rod; a bevel gear and a connecting plate fixedly mounted on one side of the threaded rod, a bevel gear rotatably mounted on one side of the connecting plate, the bevel gear rotatably meshing with the bevel gear 1; a sliding hole on the rotating rod, and an insert plate integrally formed inside the bevel gear rotatably matching the sliding hole.

[0007] Preferably, two movable plates are slidably installed on the top of the base plate, a vertical plate is fixedly installed on the top of the movable plate, a pressure plate is slidably installed on one side of the vertical plate, a sliding plate is slidably installed inside the pressure plate, a sliding rod and a spring are fixedly installed on one side of the sliding plate, the spring is sleeved on the outside of the sliding rod, a T-shaped plate is fixedly installed on the bottom of the movable plate, a motor is fixedly installed on the base plate, a threaded rod is fixedly installed on the output end of the motor, the two T-shaped plates are threadedly connected to the threaded rod, and the threaded rod has two threaded grooves with opposite directions of rotation.

[0008] Preferably, a T-shaped block is fixedly installed on one side of the clamping block, and the same fixing strip is fixedly installed on one side of the two mounting blocks located on the same side. The fixing strip has a sliding T-groove that matches the T-shaped block. A fixing cylinder is fixedly installed on one side of the bevel gear, and the fixing cylinder is rotatably installed in the connecting plate.

[0009] Preferably, round rods are fixedly installed on both sides of the sliding plate, a square groove matching the sliding plate is formed in the pressure plate, a sliding oblique hole matching the round rod is formed in the square groove, and a round hole matching the sliding rod is formed on the upright plate. The spring is fixedly connected to the upright plate.

[0010] Preferably, a circular insert plate is fixedly installed on the rotating rod, the circular insert plate is rotatably installed in the fixed block, the fixed block has a rotating plate groove that matches the circular insert plate, a square block is fixedly installed at the top of the movable plate, and the threaded rod is rotatably installed in the square block.

[0011] Preferably, two sliding blocks are fixedly installed on one side of the pressure plate, and a T-shaped strip is integrally formed on one side of the sliding block.

[0012] In this utility model, a tooling fixture for producing steel grating is described. The steel grating to be clamped is placed on the top of the base plate. The motor one, which is fixedly installed on the base plate, is started. The motor one drives the threaded rod two, which is fixedly installed on its output end, to rotate. The threaded rod two drives the two T-shaped plates connected to it to move closer to each other. When they move to a certain position, the steel grating abuts against one side of the sliding plate. The sliding plate drives the sliding rod and the two round rods to move.

The rotating rod has a sliding hole, and the second bevel gear has an integrally formed insertion plate that matches the sliding hole, allowing the second bevel gear to slide on the rotating rod. Then, the mounting plate fixedly mounted on the mounting plate is activated, causing the mounting plate to rotate the rotating rod fixedly mounted at its output end, thereby causing the two second bevel gears slidably mounted on the rotating rod to rotate, thereby causing the first bevel gear meshing with the second bevel gear to rotate. The first bevel gear drives the first threaded rod to rotate, controlling the two mounting blocks threadedly connected to the first threaded rod to move closer to each other, clamping the steel grating again.

[0014] This utility model has a reasonable structural design. Through the cooperation of multiple structures, it achieves stable clamping of steel grating. Its structure is compact and its functions are comprehensive. It can meet the clamping requirements of steel gratings of different specifications and thicknesses. At the same time, it has good adaptability and can be flexibly adjusted according to different production needs. Attached Figure Description

[0024] In this embodiment, two movable plates 2 are slidably installed at the top of the base plate 1, and a vertical plate 4 is fixedly installed at the top of the movable plate 2. A pressure plate 3 is slidably installed on one side of the vertical plate 4, and a sliding plate 20 is slidably installed inside the pressure plate 3. A sliding rod 23 and a spring 24 are fixedly installed on one side of the sliding plate 20, and the spring 24 is sleeved on the outside of the sliding rod 23. A T-shaped plate 22 is fixedly installed at the bottom of the movable plate 2. A motor 5 is fixedly installed on the base plate 1, and a threaded rod 27 is fixedly installed at the output end of the motor 5. The two T-shaped plates 22 are threadedly connected to the threaded rod 27. Two threaded grooves with opposite directions are opened on the threaded rod 27 to apply additional pressure to the steel grating and ensure its stable clamping.

[0025] In this embodiment, a T-shaped block 13 is fixedly installed on one side of the clamping block 9, and the same fixing strip 12 is fixedly installed on one side of the two mounting blocks 11 located on the same side. The fixing strip 12 has a sliding T-groove that matches the T-shaped block 13. A fixing cylinder 18 is fixedly installed on one side of the bevel gear 15. The fixing cylinder 18 is rotatably installed in the connecting plate 17. Through meshing, the power transmission between the rotating rod and the threaded rod is realized. It is used to connect the bevel gear 1 and the threaded rod 1, and at the same time supports the rotation of the bevel gear 2.

[0026] In this embodiment, round rods 21 are fixedly installed on both sides of the sliding plate 20. A square groove matching the sliding plate 20 is opened in the pressure plate 3, and a sliding oblique hole matching the round rod 21 is opened on the square groove. A round hole matching the sliding rod 23 is opened on the upright plate 4. The spring 24 is fixedly connected to the upright plate 4, forming a clamping mechanism that can automatically adjust the clamping force according to the thickness of the steel grating.

[0027] In this embodiment, a circular insert plate 26 is fixedly installed on the rotating rod 16. The circular insert plate 26 is rotatably installed in the fixed block 10. The fixed block 10 has a rotating plate groove that matches the circular insert plate 26. A square block 19 is fixedly installed on the top of the moving plate 2. The threaded rod 8 is rotatably installed in the square block 19 to provide support and a rotating platform for the threaded rod. Two sliding blocks 25 are fixedly installed on one side of the pressure plate 3. A T-shaped strip is integrally formed on one side of the sliding block 25. Sliding grooves that match the T-shaped strips are opened on both sides of the upright plate 4. A moving groove that matches the moving plate 2 and the T-shaped plate 22 is opened on the top of the bottom plate 1 to allow it to slide smoothly while maintaining its stability.

[0028] In this embodiment, during use, the steel grating to be clamped is placed at the top of the base plate 1. The motor 5, fixedly mounted on the base plate 1, is then started. The motor 5 drives the threaded rod 27, fixedly mounted at its output end, to rotate. This causes the threaded rod 27 to bring the two threaded T-shaped plates 22 closer together. When they reach a certain position, the steel grating abuts against one side of the sliding plate 20. The sliding plate 20 then moves the sliding rod 23 and the two round rods 21, causing the pressure plate 3, slidably mounted on the vertical plate 4, to press down, thus restricting the steel grating and clamping it with the two sliding plates 20. Simultaneously, the movement of the T-shaped plates 22 causes the fixing strip 12 and the square block 19 to move together, thereby moving the two mounting blocks 11 and the connecting plate 17 and the rotating mounting plate 11. The fixed cylinder 18 on the connecting plate 17 moves together with the second bevel gear 15, allowing the fixed cylinder 18 and the second bevel gear 15 to slide on the rotating rod 16. The rotating rod 16 has a sliding hole, and the second bevel gear 15 has an integrally formed plug plate that matches the sliding hole, so that the second bevel gear 15 slides on the rotating rod 16. Then, the second motor 7, which is fixedly installed on the mounting plate 6, is started, so that the second motor 7 drives the rotating rod 16, which is fixedly installed at its output end, to rotate. This drives the two second bevel gears 15, which are slidably installed on the rotating rod 16, to rotate. This drives the first bevel gear 14, which meshes with the second bevel gear 15, to rotate. The first bevel gear 14 drives the first threaded rod 8 to rotate, controlling the two mounting blocks 11, which are threadedly connected to the first threaded rod 8, to move closer to each other and clamp the steel grating again.
