Description

Technical Field

[0001] This utility model relates to the field of steel plate cutting technology, specifically to a positioning block for fixing steel plates during steel structure cutting. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The production process of steel structures requires cutting steel plates into appropriate sizes.

[0003] In the prior art, the authorized announcement number CN220740273U discloses a positioning block for fixing steel plates for cutting steel structures, including a worktable; two fixing blocks are fixed on one side of the worktable, a guide rail is provided between the fixing blocks, a control box is connected to the guide rail, a bracket is installed on the side of the control box away from the guide rail, a cutting module is provided on the end of the bracket away from the control box, and a clamping plate is provided on the lead screw.

[0004] The aforementioned device uses clamps to fix steel plates to the workbench for cutting. During the cutting process, fine debris falls through holes in the receiving plate. Because of their light weight, this debris easily disperses in the air, causing varying degrees of pollution to the working environment. To maintain a clean and tidy working environment and prevent debris accumulation from affecting work efficiency and equipment operation, users need to perform regular, thorough cleaning as needed to ensure timely and effective disposal of debris, which can be inconvenient. Utility Model Content

[0005] The purpose of this invention is to provide a positioning block for fixing steel plates when cutting steel structures, so as to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a positioning block for fixing steel plates cut by a steel structure, including a workbench, on which a slag discharge port and a movable slide groove are provided. A protective cover is fixedly installed on one side of the workbench. A positioning mechanism is installed on the workbench. The positioning mechanism includes a bidirectional threaded screw rotatably installed in the workbench and a positioning frame slidably installed on the movable slide groove. The two ends of the bidirectional threaded screw have threads in opposite directions. A screw nut is threadedly installed on the bidirectional threaded screw and is fixedly installed on the positioning frame. A pressure plate is slidably installed in the positioning frame. A threaded rod is threadedly installed on the positioning frame, and the lower end of the threaded rod is rotatably installed on the pressure plate. A collection mechanism is installed in the workbench.

[0007] Preferably, a worm gear is fixedly installed at one end of the bidirectional threaded screw, a drive shaft is rotatably installed inside the protective cover, two worm gears are fixedly installed on the drive shaft, and a crank handle is fixedly installed at one end of the drive shaft.

[0008] Preferably, a bearing is installed on the worktable, and the bidirectional threaded screw is rotatably mounted on the worktable via the bearing.

[0009] Preferably, the worm gear is rotatably mounted inside the protective cover via a drive shaft, and the worm gear meshes with the worm wheel. The positioning frame is slidably mounted on the worktable via a movable slide groove.

[0010] Preferably, the collection mechanism includes a driven roller and a drive roller rotatably mounted in the workbench, and a motor fixedly mounted in the workbench. A collection belt is rotatably mounted between the driven roller and the drive roller. A cleaning roller brush is fixedly mounted at the output end of the motor. A first gear is fixedly mounted at the end of the cleaning roller brush. A second gear is fixedly mounted at the end of the drive roller, and the first gear and the second gear mesh together. A collection port is fixedly mounted below the cleaning roller brush.

[0011] Preferably, a retainer is installed inside the worktable, and the driven roller, drive roller and cleaning brush are all rotatably mounted inside the worktable via the retainer.

[0012] Preferably, a coupling is fixedly installed at the output end of the motor, and one end of the cleaning roller brush is fixedly installed on the output end of the motor through the coupling.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this application, rotating the threaded rod drives the pressure plate downwards, achieving precise clamping and positioning of the steel plate on the worktable. Further, cranking the handle causes the worm gear on the drive shaft to rotate, which is then transmitted to the worm wheel, causing it to rotate. The rotation of the worm wheel is further converted into the rotation of the double-ended threaded rod, which in turn causes the double-ended threaded rod nut to move along the axial direction of the rod. Finally, the movement of the double-ended threaded rod nut drives the displacement of the positioning frame, achieving adjustment of the spacing between the positioning frames to facilitate precise positioning of steel plates of different lengths.

[0015] 2. In this application, the starting motor causes the cleaning roller brush to rotate, which in turn causes the first gear to rotate. The rotation of the first gear drives the second gear, which in turn drives the drive roller to rotate. The movement of the drive roller causes the collection belt to move towards the cleaning roller brush. The rotating cleaning roller brush cleans the surface of the collection belt, thereby allowing the debris on the surface of the collection belt to be discharged through the collection port, achieving the cleaning and collection of debris.

[0021] 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.

[0022] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for fixing a positioning block for cutting steel plates in steel structures. It includes a workbench 1, a slag discharge port 2 and a movable slide 3 on the workbench 1, a protective cover 4 fixedly installed on one side of the workbench 1, a positioning mechanism 5 installed on the workbench 1, and a collection mechanism 6 installed inside the workbench 1. The positioning mechanism 5 can fix steel plates of different lengths on the workbench 1, and the collection mechanism 6 can collect the cutting debris to prevent the debris from scattering randomly.

[0023] like Figure 2 and Figure 3As shown, the positioning mechanism 5 includes a bidirectional threaded screw 501 rotatably mounted in the worktable 1 and a positioning frame 503 slidably mounted on the movable slide 3. The bidirectional threaded screw 501 has threads in opposite directions at both ends. A screw nut 502 is threaded onto the bidirectional threaded screw 501 and is fixedly mounted on the positioning frame 503. A pressure plate 509 is slidably mounted inside the positioning frame 503. A threaded rod 507 is threaded onto the positioning frame 503 and its lower end is rotatably mounted on the pressure plate 509. A worm gear 504 is fixedly mounted at one end of the bidirectional threaded screw 501. A drive shaft 506 is rotatably mounted inside the protective cover 4. Two worm gears 505 are fixedly mounted on the drive shaft 506. A crank handle 508 is fixedly mounted at one end of the drive shaft 506. A bearing is mounted on the worktable 1, and the bidirectional threaded screw 501 is rotatably mounted on the worktable 1 through the bearing.

[0024] Specifically, during operation, the threaded rod 507 is first manually rotated. This action directly causes the pressure plate 509 to move downwards, thus firmly pressing the steel plate and ensuring that the steel plate is accurately positioned at the predetermined position on the worktable 1. Next, the operator turns the crank handle 508, which transmits power to the drive shaft 506, causing the worm gear 505 mounted on the drive shaft 506 to rotate. As the worm gear 505 rotates, the worm wheel 504 meshing with it also rotates. The rotation of the worm wheel 504 is further transmitted to the double-ended threaded screw 501, causing it to rotate as well. The rotation of the double-ended threaded screw 501 causes the double-ended screw nut 502 to move linearly. As the double-ended screw nut 502 moves, the positioning frame 503 connected to it also moves, ultimately achieving the function of adjusting the distance between the positioning frames 503. This meets the positioning needs of steel plates of different lengths, making the entire positioning process both flexible and precise, greatly improving work efficiency and positioning accuracy.

[0025] like Figure 2 and Figure 4 As shown, the collection mechanism 6 includes a driven roller 602 and a drive roller 603 rotatably mounted in the worktable 1, and a motor 604 fixedly mounted in the worktable 1. A collection belt 601 is rotatably mounted between the driven roller 602 and the drive roller 603. A cleaning roller brush 605 is fixedly mounted at the output end of the motor 604. A first gear 607 is fixedly mounted at the end of the cleaning roller brush 605, and a second gear 608 is fixedly mounted at the end of the drive roller 603. The first gear 607 and the second gear 608 mesh together. A collection port 606 is fixedly mounted below the cleaning roller brush 605. A retainer is installed in the worktable 1. The driven roller 602, the drive roller 603, and the cleaning roller brush 605 are all rotatably mounted in the worktable 1 through the retainer.

[0026] Specifically, after starting the motor 604, it drives the cleaning roller brush 605 to rotate. During rotation, the cleaning roller brush 605 further drives the first gear 607 to rotate. The rotation of the first gear 607 drives the second gear 608 to rotate as well. Then, the rotation of the second gear 608 drives the drive roller 603 to rotate. The rotation of the drive roller 603 causes the collection belt 601 to move towards the cleaning roller brush 605. As the collection belt 601 moves towards the cleaning roller brush 605, the rotating cleaning roller brush 605 effectively cleans the surface of the collection belt 601.

[0027] Working principle: The steel plate is placed on the worktable 1. Then, the threaded rod 507 can be rotated. After rotating the threaded rod 507, it will drive the pressure plate 509 to move downward, thereby pressing and positioning the steel plate on the worktable 1. After rotating the crank handle 508, it will drive the worm gear 505 on the drive shaft 506 to rotate. After the worm gear 505 rotates, it will drive the worm wheel 504 to rotate. After the worm wheel 504 rotates, it will drive the double-sided threaded screw 501 to rotate. After the double-sided threaded screw 501 rotates, it will drive the double-sided screw nut 502 to move. After the double-sided screw nut 502 moves, it will drive the positioning frame 503 to move, thereby adjusting the distance between the positioning frames 503, which is convenient for positioning steel plates of different lengths. The cutting debris will fall onto the collection belt 601. After the debris falls onto the collection belt 601, the motor 604 can be started. When the motor 604 is started, it will drive the cleaning roller 605 to rotate. After the cleaning roller 605 rotates, it will drive the first gear 607 to rotate. After the first gear 607 rotates, it will drive the second gear 608 to rotate. After the second gear 608 rotates, it will drive the drive roller 603 to rotate. After the drive roller 603 rotates, it will drive the collection belt 601 to move towards the cleaning roller 605. When the collection belt 601 moves towards the cleaning roller 605, the rotating cleaning roller 605 will clean the surface of the collection belt 601, so that the debris on the surface of the collection belt 601 will be discharged through the collection port 606, thus cleaning and collecting the debris and preventing the debris from scattering randomly.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
