Description

Technical Field

[0001] This utility model relates to the field of drilling device technology, specifically a drilling device for steel structure production and processing. Background Technology

[0002] In modern industry, steel structures, with their high strength, high stability, and good plasticity, are widely used in many important industries such as construction, bridges, and machinery manufacturing. Drilling is a crucial process in the production and processing of steel structures, providing a precise positioning foundation for subsequent assembly and connection, directly affecting the overall quality and performance of the steel structure product. To meet the drilling needs of steel structures of different specifications and materials, various drilling devices for steel structure production and processing have emerged. These devices typically use a high-speed rotating drill bit to contact the surface of the steel structure, forming the required holes through cutting action.

[0003] During drilling operations, the high-speed friction and intense cutting between the drill bit and the steel structure generate a large amount of metal scrap, mainly including iron filings and fragments. In actual operation, the high-speed rotating drill bit imparts significant kinetic energy to the metal scrap, causing it to fly outwards at high speeds. Because the direction of this splashing is random, and some scrap has sharp edges and high hardness, it can easily cause injury to workers' skin, eyes, and other areas if it comes into contact with them. This can range from minor scratches and cuts to more serious accidents, endangering not only the health of workers but also production progress and the company's safety management. Therefore, we propose a drilling device for steel structure production and processing. Utility Model Content

[0004] The purpose of this utility model is to provide a drilling device for steel structure production and processing, so as to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solutions: A drilling device for steel structure production and processing includes a frame, a motor fixedly connected to the top of the frame, the output end of the motor passing through the frame, a drill bit fixedly connected to the bottom of the motor output end, a processing platform fixedly connected to the surface of the frame below the drill bit, a protective component provided outside the drill bit, and a support component provided on the outer wall of the processing platform.

[0006] Preferably, the protective assembly includes a sleeve slidably connected to the drill bit. Two sets of connecting plates are symmetrically fixedly connected to the top of the sleeve, and bolts are threaded into each connecting plate. The connecting plates are fixedly connected to the drill bit by the bolts. A sliding groove is provided at the bottom of the sleeve, and a protective cylinder is slidably connected in the sliding groove. An annular scraper is fixedly connected to the bottom surface of the inner ring of the sleeve, and the outer wall of the annular scraper is in contact with the inner wall of the protective cylinder. Two sets of fixing posts are symmetrically fixedly connected to both sides of the sleeve, and two sets of sliding rods are symmetrically fixedly connected to both sides of the protective cylinder. The fixing posts and sliding rods are slidably connected. A spring is provided between the fixing posts and the sliding rods. One end of the spring is fixedly connected to the inner wall of the fixing post, and the other end of the spring is fixedly connected to the sliding rod. Both the sleeve and the protective cylinder are designed to be transparent.

[0007] Preferably, a rubber ring is fixedly connected to the bottom surface of the protective cylinder, and the rubber ring is made of nitrile rubber.

[0008] Preferably, the slide bar is cylindrical in shape, and the fixing post has a through hole that matches the slide bar.

[0009] Preferably, the support assembly includes a movable chamber fixedly connected to the front surface of the processing platform. A bidirectional lead screw is rotatably connected inside the movable chamber. Two sets of transmission blocks are threaded onto the bidirectional lead screw. A connecting block is fixedly connected to the side of each transmission block opposite to the bidirectional lead screw. A support plate is fixedly connected to the rear surface of each connecting block. A ratchet is fixedly connected to the right end of the bidirectional lead screw. A fixed seat is fixedly connected to the top surface of the movable chamber. A rotating rod is rotatably connected inside the fixed seat. A torsion spring is wound around the surface of the rotating rod. A limit block is fixedly connected to the right end surface of the rotating rod. A hole is provided on the surface of the movable chamber corresponding to the fixed seat. The limit block passes through the hole and engages with the ratchet.

[0010] Preferably, a handle is fixedly connected to the right end surface of the ratchet, and the handle is cylindrical in design.

[0011] The beneficial effects of this utility model are: 1. This utility model features a sliding protective sleeve on the outside of the drill bit. The drill bit moves the protective sleeve downwards, and the drill bit drills a hole in the workpiece. As the drill bit moves, the protective sleeve presses against the workpiece, causing the protective sleeve to slide within a fixed column and compress a spring. As the drill bit moves downwards and drills, it continuously moves the protective sleeve within a groove. This allows the protective sleeve and sleeve to work together to shield the workpiece from flying debris generated during drilling, preventing the debris from splashing outwards at high speeds and causing injury or harm to the health of workers.

[0012] 2. This utility model uses a ratchet to drive a bidirectional lead screw to rotate within the movable chamber, causing the transmission block to move in opposite directions on the bidirectional lead screw under its action. Simultaneously, a connecting block drives the support plate to move, thus achieving adjustable lateral support area of ​​the processing platform. Furthermore, the restoring force of a torsion spring drives the rotating rod to reset and rotate within the fixed seat, causing the limit block to engage with the ratchet, achieving unidirectional rotation of the ratchet. This improves the stability of the support plate and ratchet during use, enabling the processing platform to process workpieces of different lateral lengths, thereby enhancing the stability of the processing platform's support for the workpiece.

[0015] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figures 1-4As shown, a drilling device for steel structure production and processing includes a frame 1, a motor 2 fixedly connected to the top of the frame 1, the output end of the motor 2 passing through the frame 1, a drill bit 3 fixedly connected to the bottom of the output end of the motor 2, a processing platform 4 fixedly connected to the surface of the frame 1 below the drill bit 3, a protective component 5 provided outside the drill bit 3, and a support component 6 provided on the outer wall of the processing platform 4.

[0017] As a technical optimization of this utility model, the protective component 5 includes a sleeve 51 slidably connected to the drill bit 3. Two sets of connecting plates 52 are symmetrically fixedly connected to the top of the sleeve 51. Bolts 53 are threaded into the connecting plates 52. The connecting plates 52 are fixedly connected to the drill bit 3 through the bolts 53. A sliding groove 54 is opened at the bottom of the sleeve 51. A protective cylinder 55 is slidably connected in the sliding groove 54. An annular scraper 56 is fixedly connected to the bottom surface of the inner ring of the sleeve 51. The outer wall of the annular scraper 56 is in contact with the inner wall of the protective cylinder 55. Two sets of fixing posts 57 are symmetrically fixedly connected to both sides of the sleeve 51. Two sets of sliding rods 58 are symmetrically fixedly connected to both sides of the protective cylinder 55. The fixing posts 57 and the sliding rods 58 are slidably connected. A spring 59 is provided between the fixing posts 57 and the sliding rods 58. One end of the spring 59 is fixedly connected to the inner wall of the fixing post 57, and the other end of the spring 59 is fixedly connected to the sliding rod 58. Both the sleeve 51 and the protective cylinder 55 are designed to be transparent.

[0018] In practice, a sliding protective cylinder 55 is installed outside the drill bit 3, causing the drill bit 3 to move the protective cylinder 55 downwards. The drill bit 3 drills a hole in the workpiece, and the protective cylinder 55 presses against the workpiece as the drill bit 3 moves. This causes the protective cylinder 55 to move the slide rod 58 within the fixed column 57 and compress the spring 59. As the drill bit 3 moves downwards and drills, it continuously moves the protective cylinder 55 within the slide groove 54. The protective cylinder 55 cooperates with the sleeve 51 to shield the waste material splashed during drilling, preventing the waste material from splashing outwards at high speeds and causing injury or harm to the health of the workers.

[0019] As a technical optimization of this utility model, a rubber ring is fixedly connected to the bottom surface of the protective cylinder 55, and the rubber ring is made of nitrile rubber material.

[0020] In practice, the bottom of the protective cylinder 55 can be in close contact with the processing platform 4, thereby forming a sealed space between the protective cylinder 55 and the processing platform 4. This prevents the waste material splashed out from the gap between the protective cylinder 55 and the processing platform 4 when the drill bit 3 is drilling the workpiece, and prevents it from spreading in all directions, which would make it inconvenient for the staff to clean up.

[0021] As a technical optimization of this utility model, the slide rod 58 is designed in a cylindrical shape, and the fixing post 57 has a through hole that matches the slide rod 58.

[0022] In practice, this increases the contact area between the slide bar 58 and the fixed post 57, thereby improving the stability of the slide bar 58 sliding back and forth within the fixed post 57.

[0023] As a technical optimization of this utility model, the support component 6 includes a movable chamber 61 fixedly connected to the front surface of the processing platform 4. A bidirectional lead screw 62 is rotatably connected inside the movable chamber 61. Two sets of transmission blocks 63 are threadedly connected to the bidirectional lead screw 62. A connecting block 64 is fixedly connected to the side of the transmission block 63 away from the bidirectional lead screw 62. A support plate 65 is fixedly connected to the rear surface of the connecting block 64. A ratchet 66 is fixedly connected to the right end of the bidirectional lead screw 62. A fixed seat 67 is fixedly connected to the top surface of the movable chamber 61. A rotating rod 68 is rotatably connected inside the fixed seat 67. A torsion spring 69 is wound around the surface of the rotating rod 68. A limit block 610 is fixedly connected to the right end surface of the rotating rod 68. A hole is provided on the surface of the movable chamber 61 corresponding to the fixed seat 67. The limit block 610 passes through the hole and engages with the ratchet 66.

[0024] In specific implementation, the ratchet 66 drives the bidirectional lead screw 62 to rotate within the movable chamber 61, and the transmission block 63 moves in the opposite direction on the bidirectional lead screw 62 under the action of the bidirectional lead screw 62. Simultaneously, the connecting block 64 drives the support plate 65 to move, thereby achieving the purpose of adjusting the lateral support area of ​​the processing platform 4. Then, the restoring force of the torsion spring 69 drives the rotating rod 68 to reset and rotate within the fixed seat 67, and the limiting block 610 engages with the ratchet 66, thereby achieving the purpose of unidirectional rotation of the ratchet 66. This improves the stability of the support plate 65 and the ratchet 66 during use, enabling the processing platform 4 to process workpieces of different lateral lengths, and thus improving the stability of the processing platform 4 in supporting the workpiece.

[0025] As a technical optimization of this utility model, a handle is fixedly connected to the right end surface of the ratchet 66, and the handle is designed in a cylindrical shape.

[0026] In practice, it makes it easier for staff to rotate the ratchet 66, which in turn drives the bidirectional lead screw 62 to rotate within the movable chamber 61, making it more time-saving and labor-saving for staff to rotate the ratchet 66.

[0027] In use, the protective cylinder 55 is first moved downward by the drill bit 3, and the bottom of the protective cylinder 55 contacts the processing platform 4. Then, the drill bit 3 drills a hole in the workpiece. As the drill bit 3 moves, the protective cylinder 55 is pressed against the workpiece, causing the protective cylinder 55 to slide the slide rod 58 within the fixed column 57 and compress the spring 59. As the drill bit 3 moves downward, it continuously drives the protective cylinder 55 to slide within the slide groove 54. This allows the protective cylinder 55 to cooperate with the sleeve 51 to shield the waste material generated during drilling, preventing it from splashing outwards at high speed. While the protective cylinder 55 slides within the sleeve 51, the annular scraper 56 scrapes off the waste material adhering to the inner wall of the protective cylinder 55, making it ready for the next use.

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.
