Description

Technical Field

[0001] This disclosure relates to the field of drilling equipment technology, and in particular to multi-station intelligent drilling equipment for PD series composite materials. Background Technology

[0002] PD series composite materials typically refer to composite materials with palladium (Pd) as the main active component. Palladium is supported on different substrates in the form of nanoparticles or compounds, forming various structures. Due to palladium's excellent catalytic performance, the physicochemical properties of the substrate (such as high specific surface area, conductivity, or magnetism), and synergistic effects, palladium-based composites can enhance the mechanical properties of matrices such as polydicyclopentadiene in the field of advanced composite materials, and are used in automotive parts, chemical corrosion protection equipment, or engineering machinery. However, it should be noted that polydicyclopentadiene itself does not directly contain palladium; rather, its performance is improved through composite modification.

[0003] For some shell structures made of PD composite materials, drilling equipment is required to prepare for subsequent assembly. In the existing technology, the material to be drilled is clamped and fixed by a jig, and then the drilling equipment drills holes in the material. When multiple holes need to be drilled on the material surface, the material needs to be moved to align the drill rod of the drilling equipment with the drilling positions at different locations before the drilling process is completed. This process leads to low drilling efficiency and requires correction and alignment of each hole. Summary of the Invention

[0016] The technical solution provided in this disclosure may include the following beneficial effects:

[0017] 1. This invention drives two bidirectional screws to rotate via a motor and a second transmission belt. Two sets of upper and lower frames move along the surface of the bidirectional screws under the connection of the vertical plate and the sliding frame. The distance between the two sets of upper and lower frames is adjusted according to the width of the PD composite board. The first motor drives the first screw to rotate. One end of the horizontal plate slides along the sliding rod, and the other end moves along the surface of the first screw, thereby adjusting the vertical distance between the upper and lower frames. The sliding frame slides along the vertical plate to maintain the connection between the upper and lower frames. Then, the distance between the upper and lower frames is adjusted according to the thickness of the PD composite board, so that the upper and lower frames can wrap around the top and bottom sides of the PD composite board, limiting and clamping the PD composite board. At this time, the PD composite board is a certain distance away from the turntable, which provides convenience for drilling. In addition, the vacuum cleaner inside the turntable and the dust collection groove on the top of the turntable can quickly handle the debris generated by drilling.

[0018] 2. The positioning components of the present invention are arranged according to the positions where holes need to be drilled on the PD composite board. Taking the case where multiple holes need to be opened on the PD composite board as an example, multiple positioning components are needed to position the holes at different positions. Moreover, the holes at each position can be in different positions in the horizontal direction. Therefore, by sliding the movable plate on the slide along the vertical rod, the length of the second belts at both ends can be adjusted, thereby adjusting the horizontal position of the drilling. Then, the movable plate is fixed on the vertical rod by the locking bolt to keep the drilling position corresponding to the position where the hole needs to be opened on the PD composite board.

[0019] 3. In this invention, after the drilling assembly aligns with the positioning assembly, the second electric push rods at both ends of the horizontal frame drive the contact plates to descend until they press against the abutment plates at both ends of the positioning assembly. As the second electric push rods move, the first belt unfolds along the inside of the horizontal frame. During this process, because the drilling positions of the second belt on the positioning assembly are different, the positions of the moving plates at both ends fixed to the vertical rod are different, resulting in different extension lengths of the second electric push rods at both ends of the horizontal frame. As the extended ends of the second electric push rods connected to the pull ropes move, they pull out the pull ropes. During this process, because the other end of the pull rope passes through the moving notch of the slider, wraps around once, and connects to the other side of the slider, and the two sides of the slider are connected by the first spring... The spring is connected to the inner walls at both ends of the cross frame, so the movement of the slider and the drilling device can be driven by the movement of the extended end of the second electric push rod and the traction of the pull rope. The shorter the length of the extended end of the second electric push rod, the closer the bottom moving plate is to the top of the vertical rod, and the closer the drilling position is to this side. Therefore, the drilling device needs to be moved to this side as well. If it is pulled directly by the first belt, the drilling device will be opposite to the drilling direction. Therefore, after the pull rope is wrapped around and fixedly connected to the other end of the slider, the slider and the drilling device can move closer to the side with the shorter extended end of the second electric push rod, and the drilling device can correspond to the drilling position and automatically complete the adjustment of the drilling position.

[0020] 4. In this invention, the second motor on the side plate drives the second screw to rotate. The screw holder is threadedly engaged with the second screw. A slide bar moves along a groove on the turntable, causing the limiting component to move along the turntable. This moves the subsequent positioning components to the original position of the first group of positioning components. Because the drilling positions on different PD composite boards are different, the positions of the positioning components also differ. To ensure that the second screw drives the limiting component to move each time, the second, third, and fourth groups of positioning components are moved to correspond to the subsequent three groups of drilling components. Each time the limiting component moves along the turntable, it stops moving after receiving a signal from the receiving plate of each group of positioning component clamps via an infrared detection module. Simply put, in this step, the drilling component closest to the vertical frame is the first drilling position. The remaining drilling components drill holes in the PD composite board in a clockwise direction. After the turntable rotates the limiting component and the PD composite board from the first drilling position to the second drilling position, the second screw drives the limiting component and the PD composite board to move, moving the second set of positioning components to the original position of the first set of positioning components. This ensures that the second set of drilling components corresponds to the position of the second set of positioning components. In this way, subsequent drilling can be performed continuously on the PD composite board. During this process, the infrared detection module and the receiving board work together to locate the position of each set of positioning components. Because the vertical frame is close to the first drilling position, the limiting component and the PD composite board have not yet slid outwards, so there will be no movement interference due to the presence of the vertical frame.

[0039] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0040] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8As shown in the embodiment of this disclosure, a multi-station intelligent drilling equipment for PD series composite materials is proposed, comprising: a base 1, a turntable 11 rotatably mounted on the top of the base 1 via a built-in drive motor, a limiting component 3 on the top of the turntable 11, a PD composite plate 5 clamped inside the limiting component 3, multiple sets of positioning components 4 mounted on the top of the limiting component 3, the positioning components 4 covering the upper surface of the PD composite plate 5, a vertical frame 12 fixed on one side of the base 1, and a top plate 13 fixed on the top of the vertical frame 12, the center of the top plate 13 being collinear with the center of the turntable 11, and four sets of drilling rigs equidistantly mounted on the bottom of the top plate 13. Hole assembly 2; The limiting assembly 3 includes a bottom frame 32, of which there are two sets. The two sets of bottom frames 32 are symmetrically slidably mounted on the surface of the turntable 11, and an upper frame 31 is provided on the top of the bottom frame 32. The upper frame 31 and the bottom frame 32 wrap around the top and bottom of both sides of the PD composite board 5. The front and rear ends of the upper frame 31 are provided with horizontal plates 33, and the front and rear ends of the two bottom frames 32 are provided with base frames 34. The upper frame 31 and the bottom frame 32 slide along the horizontal plates 33 and the base frames 34 respectively. An extension plate 313 is slidably inserted between the upper frame 31 and the bottom frame 32; The positioning assembly 4 includes a slide block 41, of which there are two sets. The two sets of slide blocks 31 are slidably inserted between the upper frame 31 and the bottom frame 32. A second belt 43 slides through the base 41, and a drilled hole 44 is formed on the surface of the second belt 43. A movable plate 42 is provided at the upper end of the slide 41, and the second belt 43 passes through the slide 41 and is fixedly connected to the movable plate 42. A side groove 314 is formed on the inner wall of the upper frame 31, and the slide 41 slides along the inside of the side groove 314. The drilling assembly 2 includes a horizontal frame 22. Four horizontal frames 22 are equidistantly arranged at the bottom of the top plate 13, and a slider 23 is slidably connected inside the horizontal frame 22. A drilling device 25 is installed at the bottom of the slider 23. A vacuum cleaner is installed inside the turntable 11, and a vacuum groove 14 is formed at the upper end of the turntable 11. During installation, adjust the size of the limiting component 3, place the PD composite plate 5 inside the limiting component 3 and clamp it in place. Place one end of the PD composite plate 5 against the end of the limiting component 3 near the vertical frame 12. Arrange the positioning component 4 according to the position of the hole 44 to be drilled on the PD composite plate 5. Align the hole 44 of the positioning component 4 with the position of the hole to be drilled on the PD composite plate 5. Drive the turntable 11 to rotate through the motor inside the base 1. Align the positioning component 4 on the PD composite plate 5 with the four sets of drilling components 2 clockwise. Perform continuous opening and processing on the PD composite plate 5, thereby improving processing efficiency and ensuring that the position of the hole 44 is indeed aligned with the drilling components 2 at different workstations.

[0041] like Figure 2 , Figure 4 and Figure 7As shown, in some embodiments, the limiting component 3 further includes: a slide rod 35, a first screw 36, a first motor 37, and a first transmission belt 38. One end of the base frame 34 is fixedly fitted with the slide rod 35, and one end of the horizontal plate 33 is slidably sleeved on the slide rod 35. The other end of the base frame 34 is rotatably mounted with the first screw 36, and the other end of the horizontal plate 33 is threaded onto the surface of the first screw 36. The tops of the first screws 36 at both ends of the upper frame 31 are fitted with the first transmission belt 38, and the two pulleys of the first transmission belt 38 are fixedly sleeved with the tops of the two first screws 36. The base frame 34 at one end of the upper frame 31 is fixed with a first motor 37 at the top of the first screw 36, and the output end of the first motor 37 is fixedly connected to the first screw 36. A bidirectional screw 39 is rotatably installed on the outer side of the base frame 34. Two base frames 32 are threaded onto the surface of the bidirectional screw 39. A second transmission belt 310 is installed at one end of the two bidirectional screws 39. Vertical plates 311 are fixed at both ends of the base frame 32. A sliding frame 312 is fixed on the upper frame 31 at the position corresponding to the vertical plate 311, and the sliding frame 312 is slidably sleeved on the surface of the vertical plate 311.

[0042] Understandably, the motor and the second transmission belt 310 drive the two bidirectional screws 39 to rotate. The two sets of upper frames 31 and bottom frames 32 move along the surface of the bidirectional screws 39 under the connection of the vertical plate 311 and the sliding frame 312. The distance between the two sets of upper frames 31 and bottom frames 32 is adjusted according to the width of the PD composite board 5. The first motor 37 drives the first screw 36 to rotate. One end of the horizontal plate 33 slides along the sliding rod 35, and the other end moves along the surface of the first screw 36, thereby adjusting the vertical distance between the upper frame 31 and the bottom frame 32. The sliding frame 312 moves along the vertical... The plate 311 slides to maintain the connection between the upper frame 31 and the bottom frame 32, and then adjusts the distance between the upper frame 31 and the bottom frame 32 according to the thickness of the PD composite plate 5, so that the upper frame 31 and the bottom frame 32 can wrap around the top and bottom sides of the PD composite plate 5 to limit and clamp the PD composite plate 5. At this time, the PD composite plate 5 is a certain distance away from the turntable 11, which can provide convenience for drilling 44, and work with the vacuum cleaner inside the turntable 11 and the dust collection groove 14 on the top of the turntable 11 to quickly handle the debris generated by drilling 44.

[0043] like Figure 5 and Figure 6As shown, in some embodiments, the positioning assembly 4 further includes: a vertical rod 45, a second spring 46, a locking bolt 48, and a clamping plate 410. The top of the slide block 41 is fixed with the vertical rod 45, and the moving plate 42 is slidably sleeved on the surface of the vertical plate 311. The surface of the vertical rod 45 is sleeved with the second spring 46, and the bottom of the second spring 46 is fixedly connected to the moving plate 42. The bottom of the vertical rod 45 is slidably sleeved with the clamping plate 410, and the clamping plate 410 is connected to the slide block 41 by a spring. The second belt 43 slides through the clamping plate 410. The side of the moving plate 42 is threaded with the locking bolt 48, and the locking bolt 48 is in contact with the vertical rod 45.

[0044] It is understandable that the number of positioning components 4 required is the same as the number of drilling components 2. If there are six positioning components 4, then six sets of equally spaced drilling components 2 need to be installed on the top plate 13. The positioning components 4 are arranged according to the position of the hole 44 to be drilled on the PD composite board 5. Taking the need to open multiple holes on the PD composite board 5 as an example, multiple positioning components 4 are needed to position the holes at different positions. And the hole at each position can be in a different position in the horizontal direction. Therefore, by sliding the movable plate 42 on the slide block 41 along the vertical rod 45, the length of the second belt 43 at both ends is adjusted, thereby adjusting the horizontal position of the hole 44. Then, the movable plate 42 is fixed on the vertical rod 45 by the locking bolt 48 to keep the position of the hole 44 corresponding to the position of the hole to be opened on the PD composite board 5.

[0045] like Figure 5 , Figure 6 , Figure 8 and Figure 9As shown, in some embodiments, the drilling assembly 2 further includes: a long plate 21, a first electric push rod 24, and a first spring 26. The long plate 21 is fixed to one end of the top plate 13 facing the horizontal frame 22, and the long plate 21 is fixedly connected to the top of the horizontal frame 22. The first electric push rod 24 is fixed to the bottom of the slider 23, and the extended end of the first electric push rod 24 is fixedly connected to the drilling device 25. The first spring 26 is fixed to both sides of the slider 23, and the other end of the first spring 26 is fixedly connected to the inner walls of both ends of the horizontal frame 22. The second electric push rod 28 is fixed to the outer walls of both ends of the horizontal frame 22. A first belt 27 is provided inside the horizontal frame 22, and both ends of the first belt 27 slide out from both ends of the horizontal frame 22. The extended end of the second electric push rod 28 is fixedly connected to the protruding end of the first belt 27. The first belt 27 slides through the slider 23. The slider 23 has a movable notch 210 at the bottom where the first belt 27 passes through, and a pull rope 211 extends through the movable notch 210. One end of the pull rope 211 extends through one end of the horizontal frame 22 and is fixedly connected to the slider 23. The other end of the pull rope 211 extends through the other end of the horizontal frame 22. A guide post 212 is fixed on the surface of the second electric push rod 28. The pull rope 211 passes through the guide post 212 and is fixedly connected to the extended end of the second electric push rod 28. A contact plate 29 is fixed to the extended end of the second electric push rod 28. A stop plate 47 is fixed to the top of the movable plate 42 at the position corresponding to the contact plate 29. The contact plate 29 makes contact with the stop plate 47 after the extended end of the second electric push rod 28 descends.

[0046] It should be noted that after the drilling assembly 2 aligns with the positioning assembly 4, the second electric push rods 28 at both ends of the horizontal frame 22 drive the contact plates 29 to descend until they press against the abutment plates 47 at both ends of the positioning assembly 4. As the second electric push rods 28 move, the first belt 27 unfolds along the inside of the horizontal frame 22. During this process, because the drilling holes 44 of the second belt 43 on the positioning assembly 4 are at different positions, the positions of the moving plates 42 at both ends fixed to the vertical rod 45 are different, resulting in different extension lengths of the second electric push rods 28 at both ends of the horizontal frame 22. This can be referred to as the principle of stopping the motor when encountering resistance. When the extended end of the second electric push rod 28 moves downward, it will immediately stop moving when it encounters the resistance of the abutment plate 47, unless the drilling hole 44 of the second belt 43 is in the middle position. Otherwise, the heights of the moving plates 42 at both ends of the positioning assembly 4 are different, resulting in different extension lengths of the two second electric push rods 28. The second electric push rod 28 connected to the pull rope 211 pulls the pull rope 211 out as its extended end moves. During this process, because The other end of the pull rope 211 passes through the moving notch 210 of the slider 23, wraps around once, and connects to the other side of the slider 23. The two sides of the slider 23 are connected to the inner walls of the two ends of the horizontal frame 22 by the first spring 26. Therefore, the slider 23 and the drilling device 25 can be moved by the movement of the extended end of the second electric push rod 28 and the traction of the pull rope 211. In short, the shorter the length of the extended end of the second electric push rod 28, the closer the bottom moving plate 42 is to the top of the vertical rod 45, and the closer the position of the drill hole 44 is to this side. Therefore, the drilling device 25 needs to be moved to this side as well. If it is pulled directly by the first belt 27, the drilling device 25 will be in the opposite direction to the drill hole 44. Therefore, by wrapping the pull rope 211 around once and fixing it to the other end of the slider 23, the slider 23 and the drilling device 25 can move closer to the side with the shorter extended end of the second electric push rod 28, and the drilling device 25 can correspond to the position of the drill hole 44, automatically completing the adjustment of the position of the drill hole 44.

[0047] like Figure 3 , Figure 6 and Figure 10As shown, in some embodiments, the bottom ends of the base frame 34 are fixed with slide bars 64, the turntable 11 is provided with a slide groove corresponding to the position of the slide bar 64, and the slide bar 64 slides along the inside of the slide groove. The top of the turntable 11 is rotatably mounted on one side of the limiting component 3, and a screw frame 63 is threaded onto the surface of the second screw 6. The screw frame 63 is fixedly connected to one side of the base frame 34. The turntable 11 is fixed with a second motor 61 corresponding to one end of the second screw 6, and the output end of the second motor 61 is fixedly connected to the second screw 6. An infrared detection module 62 is provided on the top of the second screw 6 near the positioning component 4 of the first detection position, and the infrared detection module 62 is fixedly connected to the turntable 11. The clamping plate 410 is fixed with a receiving plate 49 corresponding to the position of the infrared detection module 62.

[0048] It should be noted that, according to Figure 2As shown, the end of the PD composite board 5 that abuts against the horizontal plate 33 and the base frame 34 of the limiting component 3 is the first detection end, that is, the positioning component 4 closest to this position is the first detection station. The subsequent positioning component 4 switches the other three sets of drilling components 2 along the subsequent positioning component 4 to drill holes 44 in the PD composite board 5 through the rotation of the turntable 11. In this process, the four sets of drilling components 2 are equidistantly distributed on the periphery of the turntable 11. Without considering the movement of the drilling device 25 along the horizontal frame 22, the drilling positions of the four sets of drilling components 2 are consistent, so it is necessary to rotate the turntable 11 each time. After rotation, the second motor 61 on the side plate drives the second screw 6 to rotate. The screw holder 63 is threadedly engaged with the second screw 6 and moves along the slide groove on the turntable 11 via the slide bar 64, driving the limiting component 3 to move along the turntable 11. This moves the subsequent positioning component 4 to the position of the original first group of positioning components 4. Because the drilling positions 44 on different PD composite boards 5 are different, the positions of the positioning components 4 are also different. In order to ensure that the second screw 6 drives the limiting component 3 to move each time, the second, third, and fourth groups of positioning components 4 are moved to correspond with the subsequent three groups of drilling components 2. Each time the limiting component 3 moves along the turntable 11, it stops moving after receiving a signal from the receiving plate 49 of the clamping plate 410 of each group of positioning components 4 via the infrared detection module 62. Simply put, in this step, the drilling component 2 closest to the vertical frame 12 is at the first drilling hole 44 position. The remaining drilling components 2 drill holes 44 in the PD composite plate 5 sequentially in a clockwise direction. After the turntable 11 rotates the limiting component 3 and the PD composite plate 5 from the first drilling hole 44 position to the second drilling hole 44 position, the second screw 6 drives the limiting component 3 and the PD composite plate 5 to move, thus... The second set of positioning components 4 moves to the original position of the first set of positioning components 4, ensuring that the second set of drilling components 2 can correspond to the position of the second set of positioning components 4. In this way, subsequent drilling 44 can be continuously drilled on the PD composite board 5. During this process, the infrared detection module 62 and the receiving board 49 cooperate to locate the position of each set of positioning components 4. Because the vertical frame 12 is close to the first drilling 44 station, the limiting component 3 and the PD composite board 5 have not yet slid outward, and there will be no movement interference due to the presence of the vertical frame 12.

[0049] Working principle:

[0050] When using the device, adjust the size of the limiting component 3. The motor and second transmission belt 310 drive the two bidirectional screws 39 to rotate. The two sets of upper frames 31 and bottom frames 32 move along the surface of the bidirectional screws 39 under the connection of the vertical plate 311 and the sliding frame 312. Adjust the distance between the two sets of upper frames 31 and bottom frames 32 according to the width of the PD composite board 5. The first motor 37 drives the first screw 36 to rotate. One end of the horizontal plate 33 slides along the sliding rod 35, and the other end moves along the surface of the first screw 36, thereby adjusting the vertical distance between the upper frame 31 and the bottom frame 32. The sliding frame 312 slides along the vertical plate 311 to maintain the connection between the upper frame 31 and the bottom frame 32. Furthermore, adjust the distance between the upper frame 31 and the bottom frame 32 according to the thickness of the PD composite board 5, so that the upper frame 31 and the bottom frame 32 can... The PD composite board 5 is wrapped around its top and bottom sides, providing a limiting clamp. At this point, the PD composite board 5 is a certain distance from the turntable 11, facilitating drilling 44. The dust collector inside the turntable 11 and the dust collection groove 14 on top of the turntable 11 quickly remove debris generated during drilling 44. After the PD composite board 5 is placed inside the limiting component 3 and clamped in place, one end of the PD composite board 5 is abutted against the end of the limiting component 3 near the vertical frame 12. Positioning components 4 are arranged according to the required drilling position of the PD composite board 5. The number of positioning components 4 is the same as the number of drilling components 2. If there are six positioning components 4, six sets of equally spaced drilling components 2 need to be installed on the top plate 13. 4. Arrange the components according to the positions of the holes 44 to be drilled on the PD composite board 5. Taking the case where multiple holes need to be drilled on the PD composite board 5 as an example, multiple positioning components 4 are needed to position the holes at different positions. Each hole can be in a different position laterally. Therefore, by sliding the movable plate 42 on the slide block 41 along the vertical rod 45, the length of the second belts 43 at both ends is adjusted, thereby adjusting the lateral position of the drill holes 44. Then, the movable plate 42 is fixed on the vertical rod 45 by the locking bolts 48 to keep the position of the drill holes 44 corresponding to the position of the holes to be drilled on the PD composite board 5. The turntable 11 is driven to rotate by the motor inside the base 1. After the drilling component 2 corresponds with the positioning component 4, the second electric push rods 28 at both ends of the horizontal frame 22 drive the contact plate 2. 9 descends until it presses against the abutment plates 47 at both ends of the positioning component 4. As the second electric push rod 28 moves, the first belt 27 unfolds along the inside of the horizontal frame 22. During this process, because the drilling holes 44 of the second belt 43 on the positioning component 4 are at different positions, the positions of the moving plates 42 at both ends fixed to the vertical rod 45 are different. Consequently, the extension lengths of the second electric push rods 28 at both ends of the horizontal frame 22 are different. This can be referred to as the principle of stopping the motor when encountering an obstacle. When the extended end of the second electric push rod 28 moves downward, it will immediately stop moving when it encounters the obstruction of the abutment plate 47. Unless the drilling holes 44 of the second belt 43 are in the middle position, the heights of the moving plates 42 at both ends of the positioning component 4 are different, and consequently, the extension lengths of the two extended ends of the second electric push rods 28 are also different.As the extended end of the second electric push rod 28, connected to the pull rope 211, moves, it pulls the pull rope 211 out. During this process, because the other end of the pull rope 211 passes through the moving notch 210 of the slider 23, wraps around once, and connects to the other side of the slider 23, and the two sides of the slider 23 are connected to the inner walls of both ends of the horizontal frame 22 by the first spring 26, the movement of the extended end of the second electric push rod 28 and the traction of the pull rope 211 can drive the slider 23 and the drilling device 25 to move. Simply put, the shorter the length of the extended end of the second electric push rod 28, the closer the bottom moving plate 42 is to the top of the vertical rod 45, and the closer the position of the drill hole 44 is to this side. Therefore, it is necessary to move the drilling device 25 to this side as well. If it is directly connected to the slider 28, the movement of the slider 23 and the drilling device 25 will be closer to this side. Pulling the first belt 27 will cause the drilling device 25 to move in the opposite direction to the drilling hole 44. Therefore, after the pull rope 211 is wrapped around and fixedly connected to the other end of the slider 23, the slider 23 and the drilling device 25 can move closer to the shorter side of the extended end of the second electric push rod 28. The drilling device 25 can correspond to the position of the drilling hole 44 and automatically complete the adjustment of the position of the drilling hole 44. The end of the PD composite plate 5 that abuts against the horizontal plate 33 of the limiting component 3 and the base frame 34 is the first detection end, that is, the positioning component 4 closest to this position is the first detection station. The subsequent positioning component 4 switches the other three sets of drilling components 2 to drill the PD composite plate 5 along the subsequent positioning component 4 through the rotation of the turntable 11. In this process, the four sets of drilling components The four sets of drilling components 2 are evenly distributed around the outer perimeter of the turntable 11. Without considering the movement of the drilling device 25 along the horizontal frame 22, the drilling positions of the holes 44 are consistent. Therefore, each time the turntable 11 rotates, the second motor 61 on the side plate drives the second screw 6 to rotate. The screw holder 63 is threadedly engaged with the second screw 6, and moves along the slide groove on the turntable 11 via the slide bar 64, driving the limiting component 3 to move along the turntable 11, thus moving the subsequent positioning component 4 to the original position of the first positioning component 4. Because the drilling positions of the holes 44 on different PD composite boards 5 are different, the positions of the positioning components 4 are also different. To ensure that the second screw 6 drives the limiting component 3 to move each time, the second, third, and fourth sets of positioning components 4 are moved to the positions of the subsequent three sets of drilling components, respectively. Corresponding to component 2, the limiting component 3 moves along the turntable 11 each time. After receiving a signal from the receiving plate 49 of the clamping plate 410 of each group of positioning components 4 via the infrared detection module 62, it stops moving. Simply put, in this step, the drilling component 2 near the end of the vertical frame 12 is the first drilling hole 44 position. The remaining drilling components 2 drill holes 44 in the PD composite plate 5 in a clockwise direction. After the turntable 11 rotates the limiting component 3 and the PD composite plate 5 from the first drilling hole 44 position to the second drilling hole 44 position, the second screw 6 drives the limiting component 3 and the PD composite plate 5 to move, moving the second group of positioning components 4 to the original position of the first group of positioning components 4, ensuring that the second group of drilling components 2 can correspond to the position of the second group of positioning components 4. In this way,Subsequent drilling 44 can perform continuous drilling on the PD composite board 5. During this process, the infrared detection module 62, in cooperation with the receiving board 49, positions of each positioning component 4 are determined. Because the vertical frame 12 is close to the first drilling position, the limiting component 3 and the PD composite board 5 have not yet slid outwards, and there will be no movement interference due to the presence of the vertical frame 12.
