Description

Technical Field

[0001] This invention relates to the field of drilling equipment technology, and specifically to an intelligent drilling device and method. Background Technology

[0002] H-beams are an economical and efficient structural material with a more optimized cross-sectional area distribution and a more reasonable strength-to-weight ratio. They are named for their cross-section, which resembles the letter "H". Because all parts of an H-beam are arranged at right angles, it has advantages such as strong bending resistance in all directions, simple construction, cost savings, and light structural weight. It has been widely used in construction, bridges, railways, and space frames.

[0003] Currently, there is a lack of specialized equipment for H-beam manufacturing and processing. Although ordinary three-dimensional drilling and CNC plasma cutting technology can be used to process and produce H-beams, it cannot fully reflect the advantages of the standardized and modular design of this steel structure building in terms of production efficiency, product precision, and overall cost.

[0004] Existing horizontal combination drilling machines have a fixed drilling position and use conveyor rollers to move the H-beam to the drilling position for drilling. After one drilling operation, the conveyor rollers move the H-beam to the next area to be drilled below the drilling machine for the next drilling operation, and so on, until the entire H-beam is drilled. However, in this drilling method, the H-beam has a certain speed during movement, and even with positioning, it will still experience some displacement. When drilling the entire H-beam, multiple movements of the H-beam are required, and the displacement gradually accumulates, affecting the drilling accuracy of the entire H-beam. This makes it difficult for existing horizontal combination drilling machines to process H-beams longer than 1 meter, and they are unable to process H-beams longer than 3 meters in steel structures. 。 Summary of the Invention

[0042] To further optimize the technical solution, multiple clamping assemblies are provided to position and clamp long H-beams; each of the double-row concave roller conveyors and each of the clamping assemblies are arranged alternately.

[0043] Further optimization of the technical solution also includes at least one of the following:

[0046] The intelligent drilling method, based on the aforementioned intelligent drilling equipment, includes the following steps:

[0047] S1. Input the H-beams into the production line;

[0048] S2. The clamping and positioning device positions the H-beam to be drilled;

[0049] S3. The control system controls the walking drilling device to move along a fixed track to the first drilling position and stop.

[0050] S4. The mobile drilling device performs drilling operations on H-beams;

[0055] To further optimize the technical solution, in step S2, when the H-beam to be processed is in place, the control system judges the position status of the H-beam based on the signals transmitted by each laser sensor. After confirming that it is normal, the system calls the processing program according to the pre-arranged production sequence and compares the length measurement values ​​to determine whether the processing material matches the processing program.

[0056] The technical solution of this invention has the following advantages:

[0057] 1. The intelligent drilling equipment provided by this invention keeps the H-beam in a fixed state during the drilling process, preventing the H-beam from shifting its drilling position due to motion inertia. Furthermore, the control system can precisely control the movement of the walking drilling device to the drilling area, resulting in higher drilling accuracy for the H-beam.

[0058] 2. The intelligent drilling equipment provided by this invention includes a movable gantry support, a side drilling mechanism, and a top drilling mechanism, all of which can be detachably mounted on the movable gantry support. It can drill holes in the web of H-beams while simultaneously drilling holes in the flanges. Drilling operations can be performed on a single machine, and the drilling process can involve sequentially drilling the sides and top of the steel plate, or simultaneously drilling the sides and top of the steel plate, thereby reducing unnecessary drilling steps and improving drilling efficiency.

[0059] 3. The intelligent drilling equipment provided by the present invention, when the side drilling mechanism is performing drilling operation, the lateral movement component drives the first multi-spindle to move laterally and performs drilling operation on H-beams through the first multi-spindle in the running state. The first multi-spindle can drill multiple holes at the same time, which greatly improves drilling efficiency.

[0060] When the top drilling mechanism is performing drilling operations, the lifting component drives the second multi-spindle to lift and lower, and the drilling operation of the H-beam is performed through the second multi-spindle in operation. The second multi-spindle can drill multiple holes at the same time, which greatly improves drilling efficiency.

[0061] 4. The intelligent drilling equipment provided by this invention enables the drilling of large circular holes with a diameter of 100mm on the web of H-beams using ordinary power heads. It combines drilling equipment and cutting and hole-opening equipment into one, and can open large circular holes while drilling with a multi-spindle, which saves both production space and production time.

[0062] 5. The intelligent drilling equipment provided by this invention features a concave double-row roller conveyor composed of two discs with a diameter of 210mm, a width of 30mm, and a spacing of 120mm. Both sides maintain a distance of approximately 30mm from the H-beam flange. This roller conveyor ensures that it will not collide with the drill bit when drilling holes in the H-beam flange, allowing the double-row concave roller conveyor to avoid the drill bit during drilling; furthermore, the 120mm distance between the two discs prevents damage to the roller conveyor when drilling 100mm diameter holes in the web.

[0063] 6. The intelligent drilling equipment provided by the present invention includes a clamping and positioning device comprising a baffle assembly and a clamping clamp assembly. After the baffle assembly blocks the end face of the H-beam, the clamping clamp assembly locks and positions the H-beam. The baffle assembly and the clamping clamp assembly cooperate with each other. The baffle assembly serves as a reference, and the specific drilling position can be determined through this reference, resulting in higher drilling accuracy.

[0064] 7. The intelligent drilling equipment provided by this invention includes an electromagnet mounted on the positioning baffle bracket. When the positioning baffle bracket is rotated into position, the electromagnet is energized, which attracts the H-beam, further enhancing the positioning effect of the H-beam. When it is necessary to release the H-beam, the electromagnet is de-energized, and the electromagnet and H-beam are no longer attracted.

[0065] 8. The intelligent drilling equipment provided by the present invention uses the two laser sensors closest to the positioning baffle bracket as signal sensors to slow down the H-beam in advance during the transmission. When the H-beam arrives, it sends a signal to the control system, which then controls the H-beam transmission system to slow down the transmission speed to prevent it from moving too fast and colliding violently with the positioning baffle bracket.

[0066] 9. The intelligent drilling equipment provided by the present invention has a length measuring device installed above the H-beam support structure. The length of the H-beam is measured by the length measuring device and compared with the set value to determine whether the processing material and processing program are compatible.

[0067] 10. The intelligent drilling method provided by this invention can drill fixed combination holes at any position on the flange of an H-beam with a length of 9 meters. When drilling each H-beam, the mobile drilling device moves to drill, effectively avoiding the problem of low drilling accuracy caused by the movement of the H-beam. Attached Figure Description

[0106] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0107] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0108] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0109] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0110] It should be noted that the H-beam in this invention is a steel structure beam with continuous openings according to the standard module. The application scenarios of H-beams include, but are not limited to, low-rise steel structure buildings.

[0111] Taking the application of H-beams in low-rise steel structure buildings as an example, such as Figure 21 As shown, the H-beam 8 includes a web 82 and two flanges 81. Small holes 83 are provided on the web 82 and the two flanges 81 for installing steel columns 9 and reinforcing ribs 10. Large circular holes 84 are provided on the web 82; these are pre-drilled holes for water, electricity, and gas lines, facilitating the installation of various pipelines on site. Therefore, steel columns can be installed at any integer multiple of the module of this beam. Combined with the separate reinforcing ribs, fully prefabricated steel column installation can be achieved.

[0112] Example 1

[0113] like Figures 1 to 19 As shown in the figure, this embodiment discloses an intelligent drilling device, including a fixed track 1, an H-beam support structure 3, a clamping and positioning device 4, a walking drilling device 2, a moving mechanism 22, an automatic core sampling device 7, and a control system.

[0114] The fixed track 1 serves as the overall support system for the equipment, and the entire equipment performs drilling operations on the fixed track 1.

[0115] The H-beam support structure 3 is set above the fixed track 1 and is suitable for supporting the H-beam 8.

[0116] The clamping and positioning device 4 is set on the fixed track 1, which is suitable for positioning the H-beam 8 to be drilled, so that the H-beam 8 will not shake during drilling, thus ensuring the normal progress of drilling.

[0117] The traveling drilling device 2 is set above the fixed track 1. The traveling drilling device 2 is equipped with a moving mechanism 22 to drive the traveling drilling device 2 to move and drill the H-beam 8 along the fixed track 1.

[0118] The control system is suitable for controlling the overall operating status of the equipment; the controlled ends of the clamping and positioning device 4, the walking drilling device 2, and the moving mechanism 22 are respectively connected to the output end of the control system.

[0119] In the aforementioned intelligent drilling equipment, once the H-beam is in place, its position remains fixed. The moving mechanism 22 drives the traveling drilling device 2 to move, which then performs the drilling. After completing one drilling operation, the traveling drilling device 2 moves to the next drilling position. Therefore, during the drilling process, the H-beam remains fixed, preventing it from shifting its drilling position due to inertia. Furthermore, the control system precisely controls the movement of the traveling drilling device 2 to the drilling area, resulting in higher drilling accuracy for the H-beam.

[0120] The device of this invention can drill fixed combination holes at any position on an H-shaped steel flange plate with a length of 9 meters.

[0121] Chinese utility model patent CN215966402U discloses an automatic punching device for H-beams. While this device can punch holes in H-beams, it can only punch holes in the web. To punch holes in the flanges, additional equipment is required. To address this technical problem, the mobile drilling device 2 of this invention includes a movable gantry support 21, a side drilling mechanism 23, and a top drilling mechanism 24. The movable gantry support 21 is horizontally mounted above the fixed track 1. The side drilling mechanism 23 is positioned at the bottom of the side wall of the movable gantry support 21 and is suitable for drilling holes in the flanges 81 of the H-beam 8. The top drilling mechanism 24 is positioned at the top of the side wall of the movable gantry support 21 and is suitable for drilling holes in the web 82 of the H-beam 8. In this embodiment, the movable gantry support 21, the side drilling mechanism 23, and the top drilling mechanism 24 can all be detachably mounted on the movable gantry support 21. While being able to drill holes in the web of the H-beam, it can also drill holes in the flange of the H-beam. The drilling operation can be performed on one machine, and the drilling process can be performed sequentially on the side and top of the steel plate, or simultaneously on the side and top of the steel plate, thereby reducing unnecessary drilling steps and improving drilling efficiency.

[0122] As a further improved implementation, the side drilling mechanism 23 can be provided in one or a pair, depending on the actual drilling requirements. When a pair of side drilling mechanisms 23 is provided, the two side drilling mechanisms are symmetrically arranged, which can simultaneously drill holes in the two flanges of the H-beam, resulting in higher drilling efficiency.

[0123] As a specific implementation method, such as Figures 11 to 13As shown, the side drilling mechanism 23 includes a first multi-spindle head 232 and a lateral movement assembly 231. The first multi-spindle head 232 has multiple first drilling shafts, suitable for drilling holes in the flanges of the H-beam 8. The lateral movement assembly 231 has a fixed end and a moving end. The fixed end of the lateral movement assembly 231 is disposed on the side wall of the movable gantry bracket 21, and the moving end of the lateral movement assembly 231 is connected to the first multi-spindle head 232 and is suitable for driving the first multi-spindle head 232 to move laterally. In this embodiment, when the side drilling mechanism 23 performs drilling operations, the lateral movement assembly 231 drives the first multi-spindle head 232 to move laterally, and the drilling operation of the H-beam is performed through the first multi-spindle head 232 in operation. The first multi-spindle head 232 can drill multiple holes simultaneously, greatly improving drilling efficiency.

[0124] The first multi-spindle unit 232 includes a first drive motor 2321, a first pulley 2322, a second pulley, a first belt 2324, a first drive shaft 2325, a first multi-spindle unit housing 2326, a first linkage structure 2327, and a first drilling shaft 2328. The output shaft of the first drive motor 2321 is connected to the first pulley 2322. The first pulley 2322 is connected to the second pulley via the first belt 2324, which is rotatably mounted on the first multi-spindle unit housing 2326. The second pulley is connected to the first drive shaft 2325, which extends into the first multi-spindle unit housing 2326 and is connected to the first linkage structure 2327. The first linkage structure 2327 drives the four first drilling shafts 2328 to rotate synchronously.

[0125] More specifically, the first linkage structure 2327 includes a driving gear and four driven gears. The driving gear is connected to the first drive shaft 2325, and the four driven gears mesh with the driving gear and are respectively connected to the first drilling shaft 2328. In this embodiment, when the first drive motor 2321 rotates, it drives the first drive shaft 2325 to rotate, which in turn drives the driving gear, driven gears, and first drilling shaft 2328 to rotate.

[0126] The lateral movement assembly 231 includes a first drilling rig base 2311, a lateral movement motor 2312, a first lead screw 2313, a first lead screw nut 2314, and a first lead screw nut fixing plate 2315. The first drilling rig base 2311 is fixedly mounted on the side wall of the movable gantry support 21. The first lead screw 2313 is rotatably mounted on the first drilling rig base 2311, and one end of the first lead screw 2313 extends out of the first drilling rig base 2311 and is connected to the lateral movement motor 2312. The first lead screw nut 2314 is threadedly fitted to the first lead screw 2313, and the first lead screw nut fixing plate 2315 is connected to the side wall of the first lead screw nut 2314. The first lead screw nut fixing plate 2315 is fixedly connected to the first multi-spindle housing 2326. When the lateral movement motor 2312 in this embodiment is started, it drives the first lead screw 2313 to rotate, which in turn drives the first lead screw nut 2314, the first lead screw nut fixing plate 2315 and the first multi-axis device 232 fixedly connected to the first lead screw nut fixing plate 2315 to move laterally.

[0127] As a further improved implementation, the top drilling mechanism 24 and the automatic core-taking device 7 are located on two opposite side walls of the movable gantry support 21. Therefore, when the H-beam moves to a workstation, drilling operations can be performed separately or simultaneously by the top drilling mechanism 24 and the automatic core-taking device 7, without affecting each other.

[0128] As a specific implementation method, such as Figures 14 to 16 As shown, the top drilling mechanism 24 includes a second multi-spindle head 242 and a lifting assembly 241. The second multi-spindle head 242 has multiple second drilling shafts, suitable for drilling holes in the web of the H-beam 8. The lifting assembly 241 has a fixed end and a movable end. The fixed end of the lifting assembly 241 is mounted on the side wall of the movable gantry bracket 21, and the movable end of the lifting assembly 241 is connected to the second multi-spindle head 242 and is suitable for driving the second multi-spindle head 242 to move up and down. In this embodiment, when the top drilling mechanism 24 is performing drilling operations, the lifting assembly 241 drives the second multi-spindle head 242 to move up and down, and the drilling operation of the H-beam is performed through the second multi-spindle head 242 in operation. The second multi-spindle head 242 can drill multiple holes simultaneously, greatly improving drilling efficiency.

[0129] The lifting assembly 241 includes a second drilling rig base 2411, a lifting motor 2412, a second lead screw 2413, a second lead screw nut 2414, and a second lead screw nut fixing plate 2415. The second drilling rig base 2411 is mounted on a movable gantry support 21. The second lead screw 2413 is rotatably mounted on the second drilling rig base 2411, with its top end extending out of the second drilling rig base 2411 and connected to the lifting motor 2412. The second lead screw nut 2414 is threaded onto the second lead screw 2413, and the second lead screw nut fixing plate 2415 is connected to the side wall of the second lead screw nut 2414, with the second lead screw nut fixing plate 2415 slidably mounted on the second drilling rig base 2411.

[0130] The first multi-spindle unit 232 and the second multi-spindle unit 242 have the same structure. The second multi-spindle unit 242 includes a second drive motor 2421, a third pulley 2422, a fourth pulley, a second belt 2424, a second drive shaft 2425, a second multi-spindle unit housing 2426, a second linkage structure 2427, and second drilling shafts 2428. The output shaft end of the second drive motor 2421 is connected to the third pulley 2422, which is connected to the fourth pulley via the second belt 2424. The third pulley 2422 is rotatably mounted on the second multi-spindle unit housing 2426. The fourth pulley is connected to the second drive shaft 2425, which extends into the second multi-spindle unit housing 2426 and is connected to the second linkage structure 2427. The second linkage structure 2427 drives the four second drilling shafts 2428 to rotate synchronously.

[0131] More specifically, the second linkage structure 2427 includes a driving gear and four driven gears. The driving gear is connected to the second drive shaft 2425, and the four driven gears mesh with the driving gear and are respectively connected to the second drilling shaft 2428. In this embodiment, when the second drive motor 2421 rotates, it drives the second drive shaft 2425 to rotate, which in turn drives the driving gear, driven gears, and second drilling shaft 2428 to rotate.

[0132] A multi-spindle drill bit equipped with a drilling machine can machine several, even a dozen or twenty holes or threads at once. With a servo feed device, it can precisely and automatically perform rapid traverse, working feed (working retraction), rapid retraction, and stop. Typical multi-spindle drill bit models can drill 2-16 holes simultaneously, greatly improving efficiency. The number of spindles in a fixed model is not limited; the drill spindle type and size can be designed and manufactured according to actual needs. The multi-spindle drill bit's main structure utilizes a gearbox and universal joint, making it easy to adjust the hole spacing, saving adjustment time. It is suitable for machining workpieces with near-circumferentially distributed holes and for machining steel parts under stress.

[0133] The walking drilling device 2 in this embodiment mainly consists of a gantry frame with a servo walking motor, a set of servo four-hole multi-axis drilling mechanisms on the left and right, a set of four-hole multi-axis drilling mechanisms on one side of the top, and a Φ100 automatic core sampling device 7 on the other side.

[0134] In order to enable the movable gantry support 21 to move along the fixed track 1, the movable gantry support 21 in this embodiment is provided with a moving mechanism 22 suitable for driving the movable gantry support 21, the side drilling mechanism 23, and the top drilling mechanism 24 to move along the fixed track 1.

[0135] More specifically, the moving mechanism 22 includes guide rails, a rack 222, a moving gear 221, and a moving motor 223. Two guide rails are provided: a first guide rail 224 and a second guide rail 225. The first guide rail 224 and the second guide rail 225 are respectively fixedly mounted on the fixed track 1 and slidably assembled with the movable gantry bracket 21. The rack 222 is fixedly mounted on the fixed track 1. The moving gear 221 meshes with the rack 222 and can move along the rack 222. The fixed end of the moving motor 223 is fixed to the movable gantry bracket 21, and the output shaft end of the moving motor 223 is connected to the moving gear 221 and adapted to drive the moving gear 221 to rotate.

[0136] It should be noted that in this embodiment, the teeth of the rack 222 are vertically arranged, with the teeth facing inwards, and the rack 222 is arranged along the direction of the fixed track 1. The moving gear 221 is horizontally arranged. The moving motor 223 is connected to the moving gear 221 via a vertically arranged motor drive shaft. The two guide rails support the movable gantry support 21. To better facilitate the sliding engagement between the movable gantry support 21 and the guide rails, a sliding plate is also provided at the bottom of the movable gantry support 21, wherein the sliding plate is slidably fitted with the guide rail.

[0137] Existing horizontal combination drilling machines use twist drills with limited diameters, making it impossible to machine large-diameter holes using twist drills. However, the requirements for H-beams necessitate the drilling of large-diameter holes, a requirement that existing horizontal combination drilling machines cannot meet.

[0138] To address the aforementioned technical issues, the mobile drilling device 2 also includes an automatic core-retrieving device 7. The automatic core-retrieving device 7 is mounted on and moves with the mobile drilling device 2. The automatic core-retrieving device 7 has a large-diameter drill barrel 71 and is suitable for drilling large-diameter holes in the H-beam 8 through the large-diameter drill barrel 71. By directly cutting and drilling the H-beam 8 through the large-diameter drill barrel 71 on the automatic core-retrieving device 7, the hole diameter drilled by the large-diameter drill barrel 71 is larger than that of traditional twist drill bits, meeting the drilling requirements of the H-beam 8. This invention enables the drilling of large circular holes with a diameter of 100mm on the web of H-beams using a common power head, combining drilling and cutting / opening equipment into one. It allows for the simultaneous drilling of large circular holes with a multi-spindle drill, saving both production space and production time.

[0139] As a specific implementation method, such as Figures 7 to 10 As shown, the automatic coring device 7 includes a large-diameter drill barrel 71, a coring device housing 76, a drill barrel drive assembly 72, and a drill barrel lifting assembly 73. The drill barrel drive assembly 72 is connected to the large-diameter drill barrel 71 and is adapted to drive the large-diameter drill barrel 71 to rotate. The drill barrel lifting assembly 73 is connected to the coring device housing 76 and is adapted to drive the large-diameter drill barrel 71 to perform lifting and lowering actions.

[0140] More specifically, the large-diameter drill barrel 71 includes a drill barrel body, side cutters 74, and bottom cutters 75. The drill barrel body is configured as a cylinder with an open bottom and a closed top. Several side cutters 74 are provided, arranged circumferentially at intervals along the side wall of the drill barrel body. Several bottom cutters 75 are provided, each located at the bottom end of the side cutters 74. In this embodiment, when the large-diameter drill barrel 71 rotates, the bottom cutters 75 cut the H-beam 8, and as the large-diameter drill barrel 71 continues to descend, the side cutters 74 and the bottom cutters 75 cooperate to punch and drill holes in the H-beam 8.

[0141] The drill barrel lifting assembly 73 includes a servo lifting motor 731, a third lead screw 732, and a third lead screw nut 733. The output shaft of the servo lifting motor 731 is connected to the third lead screw 732, and the third lead screw 732 is threaded with the third lead screw nut 733. The third lead screw nut 733 is connected to the core sampling device housing 76 through a third lead screw nut fixing plate.

[0142] The drill barrel drive assembly 72 includes a drill barrel drive motor 721, a belt conveyor structure 722, and a drill barrel connecting shaft 723. The output shaft of the drill barrel drive motor 721 is connected to the belt conveyor structure 722, and the belt conveyor structure 722 is connected to the drill barrel connecting shaft 723. The drill barrel connecting shaft 723 is connected to the large-diameter drill barrel 71.

[0143] As a specific implementation method, such as Figure 17As shown, the H-beam support structure 3 includes several double-row concave roller conveyors 31 arranged longitudinally along a fixed track 1. Each double-row concave roller conveyor 31 is suitable for supporting the web 82 of the H-beam 8. Each double-row concave roller conveyor 31 includes two discs 311, a rotating shaft 312, and two support seats 313. The discs 311 are arranged in pairs with a certain distance between them. The rotating shaft 312 is fixedly connected between the two discs 311, and both ends of the rotating shaft 312 are rotatably mounted on the support seats 313 via bearings. The top of the disc 311 contacts the web of the H-beam. A certain distance exists between the sidewall of the disc 311 and the opposite sidewall of the support seat 313 for placing the flanges of the H-beam.

[0144] When drilling holes in H-beams, the web plate serves as the positioning reference, so the roller conveyor must rest on the web plate for transport. To address this, this invention designs a concave double-row roller conveyor composed of two discs, each 210mm in diameter, 30mm wide, and spaced 120mm apart. Simultaneously, both sides maintain a distance of approximately 30mm from the H-beam flanges. This roller conveyor ensures that it will not collide with the drill bit when drilling holes in the H-beam flanges, allowing the double-row concave roller conveyor to avoid the drill bit during drilling; furthermore, the 120mm distance between the two discs prevents damage to the roller conveyor when drilling 100mm diameter holes in the web plate.

[0145] In one specific embodiment, the clamping and positioning device 4 includes a baffle assembly and a clamping clamp assembly. The baffle assembly has a blocking position that blocks the end of the H-beam 8 and a release position that allows the H-beam 8 to pass through; the blocking position and the release position can be switched. The clamping clamp assembly is provided with at least one clamp, which is arranged longitudinally along the fixed track 1 and is suitable for clamping and positioning the two flanges of the H-beam 8.

[0146] The baffle assembly is a pneumatic cylinder, hydraulic cylinder, or electric push rod swing assembly. This embodiment uses a pneumatic cylinder swing assembly as an example. Figure 18 As shown, the baffle assembly includes a cylinder 41, a cylinder base 42, and a positioning baffle bracket 43. The cylinder 41 includes a cylinder body 411, a cylinder rod 412, and a connecting ring 413. The piston rod end of the cylinder body 411 is the cylinder rod 412, and the end of the cylinder rod 412 is configured as the connecting ring 413. The connecting ring 413 is fixedly connected to a first rotating rod 433. Both ends of the first rotating rod 433 are rotatably mounted on the bottom end of the positioning baffle bracket 43 via first bearing seats 431. The fixed end of the cylinder body 411 is provided with a cylinder base 42, which is hinged to a protruding plate 435 via a hinge shaft. A second rotating rod 434 is integrally connected to the bottom end of the positioning baffle bracket 43. Both ends of the second rotating rod 434 are rotatably mounted on two second bearing seats 432, which are fixedly mounted on the side wall of the fixed track 1.

[0147] As a further improved implementation, an electromagnet 436 is provided on the positioning baffle bracket 43. When the positioning baffle bracket 43 rotates into position, the electromagnet 436 is energized, which will attract the H-beam, further enhancing the positioning effect of the H-beam. When it is necessary to release the H-beam, the electromagnet 436 is de-energized, and the electromagnet and the H-beam are no longer attracted.

[0148] The clamping assembly includes a support frame 45 and a hydraulic vise 44. The support frame 45 is located at the bottom of the hydraulic vise 44. The hydraulic vise 44 can lower the H-beam for clamping and positioning by the action of the control system.

[0149] The operation of the clamping and positioning device is as follows: When the H-beam is fed in by the double-row roller conveyor, the positioning baffle bracket 43 rises to position the H-beam in the specified position, and at the same time, the electromagnet is activated to clamp the H-beam to improve the positioning accuracy. After the material end is positioned, the bottom hydraulic vise starts to work. It mainly consists of a fixed block and a sliding block. The fixed block serves as the reference for positioning the side of the H-beam, and the sliding block clamps the two flanges of the H-beam simultaneously.

[0150] The present invention provides multiple clamping assemblies, thereby correspondingly providing multiple clamping assemblies as the length of the H-beam 8 increases, to position and clamp the long H-beam 8. Each double-row concave roller conveyor 31 and each clamping assembly are arranged alternately, ensuring that the H-beam is in contact with the roller wall of each disc 311 during clamping, thus guaranteeing the horizontality of the H-beam during clamping.

[0151] As a further improved implementation, this embodiment also includes a position detection device 6. At least one position detection device 6 is arranged along the fixed track 1, suitable for detecting the movement position of the H-beam 8, so as to decelerate the H-beam 8 in a timely manner. The signal output terminal of the position detection device 6 is connected to the input terminal of the control system.

[0152] More specifically, the position detection device 6 includes a laser sensor 61, a laser sensor mounting plate 62, and a laser reflector 63. The laser sensor 61 is fixedly mounted on the clamping assembly via the laser sensor mounting plate 62, and the laser reflector 63 is fixedly mounted on the clamping assembly, with the laser sensor 61 and the laser reflector 63 positioned opposite each other. When the H-beam moves to a position on a clamping assembly, it blocks the laser emitted by the laser sensor 61. Since the laser sensor 61 cannot receive the laser reflected by the laser reflector 63, it feeds the detection information back to the control system, which then determines the position of the H-beam.

[0153] The two laser sensors closest to the positioning baffle bracket serve as signal sensors for pre-deceleration during H-beam conveying. When the H-beam arrives, it sends a signal to the control system, which then controls the H-beam conveying system to slow down the conveying speed, preventing excessive movement and violent collisions with the positioning baffle bracket. Simultaneously, along with other sensors, they function as signal devices for identifying components on the production line.

[0154] Before processing, the dimensions of the incoming materials need to be checked for compliance. Therefore, a length measuring device 5 is installed at the end of the production line. Figure 22 As shown. The length measuring device 5 is installed above the H-beam support structure 3, and is suitable for contacting the web of the H-beam 8 as it passes by to detect the length of the H-beam 8. The signal output terminal of the length measuring device 5 is connected to the input terminal of the control system. The length measuring device 5 includes a measuring wheel 51, an encoder 52, a counter, and a connecting bracket 53. The encoder 52 is installed on the measuring wheel 51. There are two measuring wheels 51, and the two measuring wheels 51 are rotatably mounted on the connecting bracket 53. The connecting bracket 53 is fixedly mounted on the fixed track 1 by a gantry bracket.

[0155] The device mainly consists of two wear-resistant wheels with a circumference of 200mm, an encoder with a pulse rate of 1000P, and a counter. The length measuring device has an accuracy of 0.2mm. When the material enters the production line, it drives the wear-resistant wheels of the length measuring device to rotate. The wheels then drive the encoder, which divides each rotation of the wheels into 1000 signals, each signal representing 0.2mm. These signals are then transmitted to the counter, which calculates the cutting length and transmits the data to the control system.

[0156] Example 2

[0157] like Figure 20 As shown, the intelligent drilling method, based on the intelligent drilling equipment of Example 1, includes the following steps:

[0158] S1. Input H-beam 8 into the production line.

[0159] The length measuring device 5 starts working, measuring the moving distance of the H-beam and feeding the measurement information back to the control system.

[0160] When the H-beam moves to the position of a clamping clamp assembly, it will block the laser emitted by the laser sensor 61. After the laser sensor 61 can no longer receive the laser reflected by the laser reflector 63, it will feed back the detection information to the control system. The control system will know the position of the H-beam at this time and control the H-beam conveying system to slow down the conveying speed.

[0161] S2. The clamping and positioning device 4 positions the H-beam 8 to be drilled.

[0162] The positioning baffle bracket 43 is raised to position the H-beam in the specified position, and at the same time the electromagnet is activated to hold the H-beam tight to improve the positioning accuracy.

[0163] After the material ends are positioned, the hydraulic vise at the bottom begins to work, firmly clamping the flanges of the H-beam.

[0164] It should be noted that when the H-beam being processed arrives in place, the control system determines the arrival status of the H-beam 8 based on the signals transmitted by each laser sensor 61. After confirming that everything is normal, the processing program is called according to the pre-arranged production sequence, and the length measurement values ​​are compared to determine whether the processing material matches the processing program. If the values ​​are abnormal, an alarm is triggered; if the values ​​are normal, the process proceeds to the next step, and the walking drilling device 2 starts normally.

[0165] S3. The control system controls the walking drilling device 2 to start walking along the fixed track 1 and stop when it reaches the first drilling position, where the first drilling position is a designated position with a fixed distance from the end of the H-beam.

[0166] S4. After confirming that everything is normal, the traveling drilling device 2 performs drilling operations on the H-beam 8. A four-hole multi-spindle drill simultaneously drills four holes in the web. The feed during processing is controlled by a servo motor, significantly improving processing accuracy while reducing unnecessary equipment operation and time. After completing the drilling of the ends, the servo system controls the device to move to the next drilling position. Then, the four-hole multi-spindle drilling mechanisms on both sides and the automatic core-taking device 7 on top simultaneously process the H-beam. At this time, the eight holes in the two side flanges and the Φ100mm large-diameter hole in the web are being processed simultaneously, completing the workload that originally required two machines to process nine times in one go. This is more than 10 times more efficient than ordinary processing methods. Furthermore, because it eliminates the need for secondary clamping and uses a high-precision multi-spindle drill and servo traveling system, the processing accuracy is also more than doubled.

[0167] S5. The control system controls the walking drilling device 2 to move along the fixed track 1 to the next drilling position and repeats step S4.

[0168] S6. Repeat step S5 at least once until the drilling of hole 8 in the H-beam is complete. Following this drilling method, the entire H-beam can be machined as required.

[0169] S7. The clamping and positioning device 4 releases the H-beam 8, and the processed H-beam 8 is conveyed out of the production line.

[0170] The clamping clamp assembly automatically releases, the positioning baffle bracket automatically falls back, and the processed steel section is automatically conveyed to the next processing position by the roller conveyor.

[0171] The control system then determines whether the next material to be processed can be delivered based on the signal from the laser sensor. If the detection signal is normal, it proceeds to step S8; if the detection signal is abnormal, it issues an alarm.

[0172] S8. Repeat steps S1-S7 to perform the drilling operation for the next H-beam 8.

[0173] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
