Currently, CNC drilling machines are primarily used for drilling holes in steel structures.

[0003] After searching, the invention patent with publication number CN116571787B discloses a drilling device and method for steel structure production. The position of the mounting plate 1 is adjusted according to the length of the steel structure to be drilled. After the mounting plate 1 is slid to the appropriate position on the upper end of the operating block, it is fixed by hand-tightening bolt 1. When the position of the hole to be drilled on the steel structure is required, the mounting plate 2 is slid on the operating block with the drilling component, moved to the appropriate position, and fixed by hand-tightening bolt 2. Steel structures of different lengths and different parts of the steel structure can be drilled.

[0010] A further technical improvement of the present invention is that the positioning assembly includes a positioning unit 1 for positioning the angle steel, a positioning unit 2 for positioning the steel plate, and a positioning unit 3 for positioning the H-shaped steel and the U-shaped steel. The positioning unit 1 includes a limiting plate 2 driven by a rotating motor 1 and limiting the position of one side of the angle steel, and a limiting plate 1 driven by a rotating motor 2 and limiting the position of the other side of the angle steel. When positioning, first flip the second limiting plate to the same bevel angle as the angle steel, and then rotate the limiting plate clockwise repeatedly to position the other side of the angle steel; When releasing, the lifting seat first descends to make the transfer belt flush with the output belt, and the limiting plate rotates counterclockwise to reset.

Slideway DETAILED DESCRIPTION

[0020] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0021] See also Figures 1-6 As shown, the present invention provides a rapid drilling device for steel structure production, comprising a drilling chamber 1 for drilling holes in different steel structures, wherein the four sides of the drilling chamber 1 are provided with an inlet 2 and an outlet, and the outlet is located directly below the inlet 2; The four sides of the drilling chamber 1 are provided with a transmission unit for conveying the corresponding steel structure parts, and a lifting seat 14 is provided inside the drilling chamber 1 for lifting; When rising, the lifting seat 14 is at the same height as the entrance 2; When descending, the lifting seat 14 is at the same height as the exit; The surface of the lifting seat 14 is provided with a transfer unit used in conjunction with the corresponding transmission unit, and each transfer unit is internally provided with a positioning assembly clamped by different steel structures; The top of the inner cavity of the drilling chamber 1 is lifted and lowered with four groups of drilling units used in conjunction with the positioning assembly. One group of drilling units is used for drilling holes in the diagonal steel, which includes a longitudinally sliding slide 26. The lower surface of the slide 26 is equipped with a clamping cylinder 18. The two driving ends of the clamping cylinder 18 are respectively connected to push columns 27. The end of each push column 27 is movably sleeved with a connecting sleeve 29, and the outer surface of the push column 27 is sleeved with a spring 28. One end of the spring 28 is fixed to the connecting sleeve 29. The upper part of the inner cavity of the connecting sleeve 29 is provided with a slideway 32 for sliding the push column 27, and the lower part of the inner cavity of the connecting sleeve 29 is provided with an inclined path connected to the slideway 32. A push seat 30 is slidably installed in the inclined path, which abuts against the end of the push column 27. A drill rod 20 driven by a servo motor and used for drilling holes in the side of the diagonal steel is installed on the push seat 30, and a spring 31 fixed to the end of the inclined path is installed at the end of the push seat 30. A fixing plate 19 is fixedly provided inside the drilling chamber 1 just below the corresponding connecting sleeve 29. The height of the fixing plate 19 is higher than the height of the angle steel. like Figure 3 As shown, initially, the height of the lifting seat 14 is consistent with the height of the four entrances 2, and the conveyor belt 4 in the transmission unit is consistent with the height of the transfer unit; Different types of steel structures (such as angle steel, steel plates, U-shaped steel, and H-shaped steel) are conveyed by different conveyor belts 4 through corresponding entrances 2 into the drilling chamber 1 and ultimately arrive at the transfer unit. Positioning components are first used to position and clamp the corresponding steel structures, ensuring that all incoming workpieces are accurately positioned before drilling, ensuring that their drilling positions are always the same. This avoids drilling deviations caused by differences in feeding direction, structural dimensions, or human errors, significantly improving drilling accuracy and consistency and reducing defective product rates. The angle steel is placed in an inverted V shape, and its drilling height exceeds that of the steel plate and U-shaped steel; When drilling a hole in a steel structure, the four groups of drilling units descend together, and the push column 27 in one group of drilling units drives the connecting sleeve 29 to slide to the specified position (just above the fixing plate 19) under the drive of the clamping cylinder 18. During the descent, the bottom surface of the connecting sleeve 29 is tightly fitted with the fixing plate 19. At this time, the end of the push column 27 slides in the slideway 32. In this state, the spring 28 is elastically deformed, and the push column 27 is continuously pushed downward, so that its end approaches the inclined path. At this time, the push column 27 and the surface of the push seat 30 are pushed against each other, generating a linear push effect. The push seat 30 slides along the inclined path and squeezes the spring 31, causing the spring 31 to undergo elastic deformation, providing flexible damping and buffering effects. The drill rod 20 installed at the front end of the push seat 30 moves downward accordingly, and the drill rod 20 finally approaches and contacts the inclined surface of the angle steel vertically, completing the precise drilling operation on the edge of the angle steel. During the entire process, spring 28 and spring 31 work together to ensure that the drilling action has controllable propulsion, flexible contact and stable limit features, which can effectively prevent the angle steel from being subjected to excessive force or the drill bit from being unstable due to impact, thereby ensuring drilling accuracy and equipment service life. Since the slide plates 26 in each drilling unit are of sliding design, holes can be drilled on different surfaces of the steel structure; At the same time, the other three groups of drilling units correspond to the positions of steel plates, U-shaped steels and H-shaped steels respectively, and complete the corresponding drilling actions after descending by cooperating with their respective positioning components; Each type of drilling unit realizes synchronous control and independent operation through differentiated positioning settings according to the height and structure of the workpiece; After the drilling operation is completed, each drilling unit stops drilling and rises in turn, the servo motor reverses to make the drill rod withdraw from the hole, and at the same time, the spring 31 returns to its original state, driving the push seat 30 to slide back to its initial position; the push column 27 returns to its position upward under the release of the elastic force of the spring 28, and releases the contact with the push seat 30; Then the lifting seat 14 descends to a position consistent with the outlet height, and the various processed steel structures are transported from the outlet direction of the corresponding side and leave the interior of the drilling chamber 1, completing a drilling cycle and improving its drilling efficiency.

[0022] See Figure 1 As shown, the transmission unit includes an upper support plate 3 fixed on each outer wall surface of the drilling chamber 1, and a conveyor belt 4 is provided on the middle surface of the upper support plate 3; A lower support plate 5 is provided below the upper support plate 3, and an output belt 6 is provided on the middle surface of the lower support plate 5; The conveying direction of the output belt 6 is opposite to that of the conveyor belt 4. Initially, the height of the lifting seat 14 is consistent with the height of the entrance 2, and the height of the transfer unit is consistent with that of the conveyor belt 4. Different steel structures are transported by the conveyor belt 4 on the corresponding side and arrive at the transfer unit. After drilling is completed, the lifting seat 14 drives the workpiece downward to make the height of the transfer unit consistent with that of the output belt 6. By reversing the transfer unit, the steel structure after drilling is automatically discharged.

[0023] See Figure 4 and Figure 5 As shown, each transfer unit includes two transfer strips 21. The initial transfer strips 21 are at the same height as the conveyor belt 4, so that the steel structure can smoothly transition to the top of the transfer strip 21 during the process of being transported from the conveyor belt 4 to the lifting seat 14, realizing seamless docking and smooth transmission. The farthest end distance of the two transfer strips 21 is consistent with the width of the conveyor belt 4, ensuring that different steel structures maintain stable support when being transported to the transfer strip 21, avoiding jamming, tilting or offsetting, which is conducive to the subsequent positioning component precise clamping and drilling operations.

[0024] See Figure 3 and Figure 4 As shown, the positioning assembly includes a positioning unit 1 for positioning the angle steel, a positioning unit 2 for positioning the steel plate, and a positioning unit 3 for positioning the H-shaped steel and the U-shaped steel. The positioning unit 1 includes a limiting plate 23 driven by the rotating motor 1 and limiting the position of one side of the angle steel, and a limiting plate 1 22 driven by the rotating motor 2 and limiting the position of the other side of the angle steel. There are two groups of positioning units three, and each group of positioning units three is adjacent to positioning unit one; When positioning, the second limiting plate 23 is first turned to the same bevel angle as the angle steel, and then the first limiting plate 22 is rotated clockwise to position the other side of the angle steel; When releasing, the lifting seat 14 first descends to make the transfer belt 21 flush with the height of the output belt 6, and the limiting plate 22 rotates counterclockwise to reset; Since the limiting plate 23 has been positioned on one side of the angle steel, the rotating motor 2 drives the limiting plate 1 22 to rotate so that it is positioned on the other side of the angle steel, completing the positioning operation of the angle steel and making the drilling position at the preset position. When the drilling unit is working, the hole position accuracy is high.

[0025] See Figure 3 As shown, a base 15 is provided at the bottom of the drilling chamber 1, and a lifting cylinder 16 is installed at the bottom of the inner cavity of the base 15, and the pushing end of the lifting cylinder 16 is fixed to the center of the bottom surface of the lifting seat 14; When the lifting cylinder 16 extends or contracts, it drives the lifting seat 14 to move up and down in the vertical direction, realizing the height conversion action of the workpiece between the transfer unit and the entrance 2 and the exit; The transfer unit and positioning assembly installed on the lifting seat 14 are lifted and lowered accordingly, so that they are at the same height as the transfer unit entrance 2 in the feeding state; In the discharge state, it is highly consistent with the output belt 6, ensuring that the workpiece can smoothly enter and exit the positioning area, and cooperate with the drilling action to complete the entire automatic cycle.

[0026] See Figure 4 As shown, both the positioning unit 2 and the positioning unit 3 include two limiting plates 3 24 , and the two limiting plates 3 24 are driven by corresponding rotating motors 3; Each limiting plate three 24 is driven by a corresponding set of rotating motors three, and can be rotated to a clamping position before processing, and then reversed to a release position after processing is completed, thereby realizing automatic clamping and unclamping of steel components. It is suitable for steel plates, U-shaped steels and H-shaped steels with relatively regular shapes and symmetrical limit on both sides.

[0027] See Figure 3 and Figure 4 As shown, the remaining drilling units all include two drill rods 25 that are close to or away from each other and driven by a drilling motor. The two drill rods 25 on the side away from the fixed plate 19 are fixed to the slides 26 on the corresponding side. The sliding direction of the slides 26 is perpendicular to the feeding direction of the transfer strip 21. The two drill rods 25 that are close to or far away from each other are adapted to drilling holes in workpieces of different sizes, and slide in the direction of the corresponding side to drill holes in different positions of the workpiece to meet its processing requirements; A top plate 13 is provided on the top of the inner cavity of the drilling chamber 1 , and an electric push rod 17 is installed on the bottom surface of the top plate 13 . The pushing end of the electric push rod 17 is connected to a lifting plate, and the lifting plate is fixed to the four sets of drilling units.

[0028] See Figure 2 and Figure 3As shown, a sealing plate 7 is provided on the inner side of each entrance 2 for lifting, and a fitting groove 8 is provided on the inner wall of the drilling chamber 1. The top of the sealing plate 7 is provided with an upward inclined surface toward the inner wall of the drilling chamber 1, and a guide rod is provided inside the fitting groove 8. The protrusion on the top of the sealing plate 7 extends into the fitting groove 8 and slides with the guide rod. A spring 12 is sleeved on the guide rod, and one end of the spring 12 is fixed to the protrusion, and the other end is fixed to the bottom end of the fitting groove 8. Each sealing plate 7 is provided with an adjustment plate 10 that moves toward the inlet 2 on the corresponding side, and the bottom end of the adjustment plate 10 is connected to a push block 11 that abuts against the sealing plate 7; Four simultaneously rotating transmission screws 9 are installed at the top of the inner cavity of the drilling chamber 1. The transmission screws 9 are threadedly connected to the adjustment plate 10, and the adjustment plate 10 passes through the top plate 13; The end of the push block 11 is provided with a ball that contacts the inclined surface; Initially, the four entrances 2 are simultaneously in the open state. After the steel structure enters the drilling chamber 1 through the entrance 2, the four adjustment plates 10 move toward the inner wall of the corresponding drilling chamber 1. At this time, the ball on the push block 11 contacts the inclined surface on the top of the sealing plate 7. Under the push of the inclined surface, the sealing plate 7 generates a downward thrust and slides downward along the guide rod, compressing the spring 12 set thereon. The spring 12 undergoes elastic deformation, providing an upward rebound force and buffering protection for the sealing plate 7, thereby realizing the linkage descending action of multiple sealing plates 7. After the workpiece is positioned, the entrance 2 is quickly closed to provide a stable and relatively closed processing environment inside the drilling chamber 1. This effectively prevents dust and debris from flying during the drilling process, improves the safety and cleanliness of the equipment and the processing accuracy of structural parts; at the same time, it prevents foreign objects from flying out and injuring people.

[0029] When the present invention is in use, the height of the lifting seat 14 is consistent with that of the entrance 2. Different steel structures enter the transfer unit in the drilling chamber 1 from the entrances 2 in four directions, are differentially positioned by the corresponding positioning components, and then quickly drilled by the drilling components. The lifting seat 14 descends to the same height as the exit, and the various processed steel structures are transported from the exit direction on the corresponding side and leave the interior of the drilling chamber 1, completing one drilling cycle and improving its drilling efficiency. By setting the drilling unit, the four groups of drilling units are lowered together. The push column 27 in one group of drilling units drives the connecting sleeve 29 to slide to the top of the fixed plate 19 under the drive of the clamping cylinder 18. The bottom surface of the connecting sleeve 29 is tightly fitted with the fixed plate 19. The end of the push column 27 slides in the slide 32, causing the spring 28 to elastically deform. The push column 27 is continuously pushed downward, causing its end to approach the ramp. At this time, the push column 27 and the surface of the push seat 30 are pushed, generating a linear push effect, and the push seat 30 moves along the ramp. The push rod 20 at the front end of the push seat 30 moves downward accordingly, and the drill rod 20 finally approaches and contacts the inclined surface of the angle steel vertically, completing the precise drilling operation on the edge of the angle steel. During the whole process, the spring 28 and the spring 31 work together, so that the drilling action has the characteristics of controllable propulsion, flexible contact and stable limit, which can effectively prevent the angle steel from being subjected to excessive force or the drill bit from being unstable due to impact, thereby ensuring the drilling accuracy and the service life of the equipment. The four adjustment plates 10 move toward the inner wall of the corresponding drilling chamber 1 respectively. At this time, the ball on the push block 11 contacts the inclined surface on the top of the sealing plate 7. Under the push of the inclined surface, the sealing plate 7 generates a downward thrust and slides downward along the guide rod, compressing the spring 12 on which it is mounted. The spring 12 undergoes elastic deformation, providing an upward rebound force and buffering protection for the sealing plate 7, realizing the linked descending action of multiple sealing plates 7, and quickly closing the entrance 2 after the workpiece is positioned, providing a stable and relatively closed processing environment for the inside of the drilling chamber 1.
