Description

Technical Field

[0001] This utility model relates to the field of bulb flat steel processing technology, specifically a sturdy bulb flat steel clamp. Background Technology

[0002] Bulb flats are a type of medium-sized steel profile mainly used in shipbuilding and bridge construction. Marine bulb flats are a type of auxiliary medium-sized steel profile used in shipbuilding. In recent years, with the rapid development of the shipbuilding industry, the demand for marine bulb flats has been strong. Generally, larger ships and standard vessels mostly use marine bulb flats for their main hull design, employing bulb flats of the same thickness and material as the connecting plates as the ribs (also called skeletons or keels).

[0003] In the existing technology, a planer is used to plan flat steel when processing it. However, when processing wall panels that are much larger than regular plates, the problem of exceeding the original processing range of the planer fixture (usually a traditional bench vise) occurs. When the workpiece is mounted on the traditional bench vise, the workpiece position is too low due to the shallow depth of the vise. Therefore, no matter how the workpiece position is adjusted, the cutting tool cannot contact the processing surface and processing cannot be performed. Utility Model Content

[0004] The purpose of this invention is to provide a robust ball flat steel clamp to solve the problem mentioned in the background art where, when processing wall panels much larger than conventional plates, the workpiece exceeds the original processing range of the planer clamp (usually a traditional bench vise). When the workpiece is mounted on a traditional bench vise, the workpiece position is too low due to the shallow depth of the vise, making it impossible for the cutting tool to contact the processing surface regardless of the workpiece position adjustment. This solution directly lifts the ball flat steel workpiece to a significant height, and with the design of multiple circular clamping plates, multiple clamping points can be formed on the web of the ball flat steel from top to bottom. This not only evenly distributes the clamping force and greatly enhances the stability of the workpiece during planing, but also ensures that even the processing surface of large-sized wall panels is accurately within the effective stroke range of the planer tool, fundamentally solving the problem of insufficient depth in traditional bench vises that prevents processing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a robust bulb flat steel clamp, comprising a planer, a planer blade, a bulb flat steel body, and a clamping mechanism. The clamping mechanism fixes the bulb flat steel body. The planer blade is positioned above the bulb flat steel body. The clamping mechanism includes a worktable, a base plate, a first limiting plate, a second limiting plate, and a clamping plate. The worktable is mounted on the planer. The upper end of the worktable is slidably connected to the base plate via fasteners. The upper end of the base plate is welded with the first limiting plate and the second limiting plate. The end wall of the first limiting plate near the second limiting plate is movably provided with a clamping plate that cooperates with the second limiting plate to clamp and fix the bulb flat steel body.

[0006] In a preferred embodiment: the planer is mounted on a slide at one end of the planer, and the thickness of the first limiting plate, the second limiting plate and the base plate is 30mm.

[0007] In a preferred embodiment: the number of clamps is several, and the shape of the clamps is circular.

[0008] In a preferred embodiment: the first limiting plate has a plurality of grooves for accommodating the clamping plate, and the end wall of the clamping plate near the bulb flat steel body has anti-slip texture.

[0009] In a preferred embodiment: the tightening member includes a first fastening bolt and a tightening nut, the number of the first fastening bolts corresponds to the number of clamps, one end of the first fastening bolt is fixedly connected to the clamp, and the other end of the first fastening bolt is fixedly connected to the tightening nut.

[0010] In a preferred embodiment: the fastener includes a limiting groove, a second fastening bolt and a fastening nut. Two sets of limiting grooves are provided at both ends of the base plate. Each set of limiting grooves consists of two grooves that are symmetrically distributed. A second fastening bolt is provided in each limiting groove, and a fastening nut is threaded onto the outer wall of the second fastening bolt.

[0011] In a preferred embodiment, a washer is fitted on the outer wall of the second fastening bolt, and the washer is disposed between the fastening nut and the base plate.

[0012] In a preferred embodiment: the workbench wall is further provided with a number of equally spaced sliding grooves, the sliding grooves are T-shaped, and the lower end of the base plate is fixedly connected to a T-shaped slider, the slider sliding in the sliding groove.

[0013] In a preferred embodiment, the lower ends of the plurality of second fastening bolts are all fixedly connected to the groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By using a 30mm thickened base plate and limiting plate, the ball flat steel workpiece is significantly lifted. Combined with the design of multiple circular clamping plates, multiple clamping points can be formed on the web of the ball flat steel from top to bottom. This not only effectively avoids the problem of workpiece tilting or twisting that may be caused by single-point clamping, but also distributes the clamping force evenly, greatly enhancing the stability of the workpiece during planing. It also ensures that even the surface to be processed of large-sized wall panels is accurately within the effective stroke range of the planer, fundamentally solving the problem of traditional bench vises being unable to process due to insufficient depth.

[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] Please see Figure 1 and Figure 3 One embodiment provided by this utility model:

[0020] A robust bulb flat steel clamp includes a planer 1, a planer blade 2, a bulb flat steel body 3, and a clamping mechanism. The clamping mechanism fixes the bulb flat steel body 3. The planer blade 2 is positioned above the bulb flat steel body 3 and is mounted on a slide at one end of the planer 1. The clamping mechanism includes a worktable 4, a base plate 5, a first limiting plate 6, a second limiting plate 7, and clamping plates 8. The worktable 4 is mounted on the planer 1. The upper end of the worktable 4 is slidably connected to the base plate 5 via fasteners. The upper end of the base plate 5 is welded with the first limiting plate 6 and the second limiting plate 7. The first limiting plate 6, near the second limiting plate 7, has a clamping plate 8 that works with the second limiting plate 7 to clamp and fix the bulb flat steel body 3 via a tightening device. There are several clamping plates 8, and each clamping plate 8 is circular in shape. The thickness of the first limiting plate 6, the second limiting plate 7, and the base plate 5 is 30 mm.

[0021] Please see Figure 4In this embodiment, the first limiting plate 6 is provided with several grooves 9 for storing the clamping plate 8. The grooves 9 can store the clamping plate 8 when not in operation, so that the inner side of the fixture forms a flat backing surface. This not only protects the clamping plate 8 from being damaged by collision, but also completely eliminates the interference caused by it when the workpiece is put in and taken out, making the loading and unloading operation smoother and safer. The end wall of the clamping plate 8 near the bulb flat steel body 3 is provided with anti-slip texture. The anti-slip texture further increases the friction and provides stronger anti-slip ability under the same clamping force, increasing the stability of the workpiece during the processing.

[0022] Please see Figure 3 In this embodiment, the tightening component includes a first fastening bolt 10 and a loosening nut 11. The number of first fastening bolts 10 corresponds to the number of clamps 8. One end of the first fastening bolt 10 is fixedly connected to the clamp 8, and the other end of the first fastening bolt 10 is fixedly connected to the loosening nut 11. The operator can easily tighten or loosen the clamp 8 by rotating the loosening nut 11, thereby clamping or loosening the ball flat steel body 3. The operation is convenient and labor-saving.

[0023] Please see Figure 2 and Figure 3 In this embodiment, the fastener includes a limiting groove 12, a second fastening bolt 13, and a fastening nut 14. Two sets of limiting grooves 12 are provided at both ends of the base plate 5. There are two limiting grooves 12 in each set, which are symmetrically distributed. A second fastening bolt 13 is provided in each limiting groove 12. A fastening nut 14 is threaded on the outer wall of the second fastening bolt 13. By tightening the fastening nut 14, the base plate 5 can be firmly pressed onto the worktable 4.

[0024] Please see Figure 3 In this embodiment, a washer 15 is fitted on the outer wall of the second fastening bolt 13. The washer 15 is located between the fastening nut 14 and the base plate 5. The washer 15 can prevent the fastening nut 14 from damaging the surface of the base plate 5 when it is tightened, and increase the stability of the connection.

[0025] Please see Figure 2 and Figure 4 In this embodiment, the worktable 4 is also provided with several equally spaced sliding grooves 16. The sliding grooves 16 are T-shaped, and the lower end of the base plate 5 is fixedly connected to a T-shaped slider 17. The slider 17 slides in the sliding groove 16. The cooperation between the T-shaped groove and the T-shaped slider 17 allows the base plate 5 to move flexibly and smoothly along the direction of the sliding groove 16. This facilitates the adjustment of the clamping position according to the length of the workpiece. It can quickly adjust the fixture to the optimal position before processing according to the specific position of the planer 2 or the processing part of the workpiece, so that the heavy workpiece can no longer be moved repeatedly, which greatly improves the clamping efficiency and processing flexibility.

[0026] Please see Figure 2In this embodiment, the lower ends of the plurality of second fastening bolts 13 are all fixedly connected to the slide groove 16.

[0027] During processing, first, according to the position of the planer 2, loosen the fastening nut 14, push the base plate 5 along the slide groove 16 to the appropriate position, then tighten the fastening nut 14 to fix the base plate 5. Then, place the bulb flat steel body 3 on the base plate 5, so that one side is close to the second limiting plate 7. Then, the operator rotates the loosening nut 11 clockwise, and pushes the multiple circular clamping plates 8 forward through multiple first fastening bolts 10 until they are tightly pressed against the other side of the bulb flat steel body 3 to complete the clamping. Since the first limiting plate 6 and the second limiting plate 7 are relatively deep, they can be used with clamping plates 8 at different positions to fix the bulb flat steel body 3. The surface of the bulb flat steel body 3 to be processed is lifted into the effective stroke range of the planer 2. Start the planer 1, and the slide ram drives the planer 2 to perform reciprocating planing motion, so that the bulb flat steel body 3 can be processed.

It should be noted that parts not described in this utility model are identical to or can be implemented using existing technology, and that this utility model can be implemented in other specific forms without departing from its spirit or essential characteristics.
