Description

Technical Field

[0001] This invention relates to the field of aluminum processing technology, specifically to an automatic drilling device for aluminum processing and its working method. Background Technology

[0002] As the application of aluminum in small hardware accessories, outdoor security facilities, personalized home customization, and on-site repair and construction continues to expand, the demand for small-batch, multi-variety, and mobile aluminum drilling processing continues to grow. However, current aluminum drilling equipment on the market is insufficient to meet the core needs of these scenarios and has many obvious shortcomings:

[0003] Lack of adaptability to large equipment: Traditional automatic drilling equipment for aluminum materials used in large-scale production is mostly a fixed, integrated structure. It is bulky and heavy, and cannot be moved flexibly or quickly assembled on site. It can only be adapted to batch processing scenarios in factory workshops, and cannot meet the needs of small processing plants, outdoor operations, temporary construction sites and other places for equipment mobility.

[0004] In scenarios lacking compatible automated equipment, users often rely on manual drilling tools. This is not only labor-intensive, but the accuracy of drilling positions and the consistency of hole diameter depend entirely on the operator's experience, making it difficult to guarantee processing quality and resulting in extremely low work efficiency. Operators must maintain fixed postures such as bending over and raising their arms for extended periods, leading to extremely high labor intensity. Furthermore, single-hole operations are time-consuming, making it difficult to adapt to large-scale, high-efficiency installation needs. In addition, the drilling requirements vary for different specifications of aluminum materials, and handheld operation requires frequent manual adjustments to stance and angle, resulting in poor adaptability and further reducing work continuity. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic drilling device for aluminum processing and its working method, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic drilling device for aluminum processing, comprising a fixed assembly, a drilling assembly, and a support assembly detachably connected as a whole, wherein the support assembly is connected between the drilling assembly and the fixed assembly; the drilling assembly includes a drilling host, a fixed seat, a base, and a lead screw drive mechanism, the drilling assembly being fixedly mounted on the fixed seat, the lead screw drive mechanism being disposed at the upper end of the base, the fixed seat being connected to the movable end of the lead screw drive mechanism, thereby driving the drilling host to perform lifting and lowering movements, and a pressure plate assembly being disposed on the outer peripheral surface of the drilling host, the pressure plate assembly applying pressure to the surface of the aluminum material to stabilize it as the drilling host descends;

[0007] The fixing component includes a base and a clamping and moving mechanism. The top of the base has a positioning groove along its length, and the clamping and moving mechanism is respectively arranged on both sides of the positioning groove. The clamping and moving mechanism is used to clamp the aluminum material and drive it to move along the Y-axis. The support component includes a support frame, a guide frame, and an X-axis moving mechanism. The guide frame is assembled on the top of the support frame, and the bottom of the support frame is connected to the base. The X-axis moving mechanism is slidably arranged on the guide frame, and the base is assembled on it. The base is provided with a stabilizing component. When the drilling host descends, it will squeeze the stabilizing component to move down and abut against the guide frame, thereby stabilizing the X-axis moving mechanism.

[0008] Furthermore, a movable groove is provided on the rear side of the top of the guide frame, and a rack is provided at the bottom of the movable groove. The X-axis moving mechanism includes a support base and an adjusting gear. The support base is slidably mounted on the guide frame, and the adjusting gear is rotatably mounted on the bottom of the support base and extends to mesh with the rack, and is driven by a first motor inside the support base. The base is detachably mounted on the support base. A guide groove is provided on the front side of the top of the guide frame, and guide wheels are provided on both the left and right sides of the bottom of the support base. The guide wheels roll within the guide groove.

[0009] Furthermore, the stabilizing component includes a stabilizing rod and a stabilizing block with the bottom end of the stabilizing rod. A sliding hole is provided in the center of the front side of the base, and a corresponding through-hole is provided on the support base, extending through to the guide groove. The stabilizing rod is slidably mounted on the sliding hole, and the upper part of the stabilizing rod extends through to the top of the base. The top end of the stabilizing rod is provided on a pressure plate, which is located below the fixed base. A first spring is connected between the pressure plate and the base. This first spring is a variable pitch spring, which will press down on the stabilizing rod to move down first when the fixed base descends.

[0010] Furthermore, both the base and the support frame are threaded with several connecting knobs, and both the support and the base are provided with matching threaded holes, so that by rotating the connecting knobs, the threaded rods on them can be screwed into the threaded holes to achieve connection.

[0011] Furthermore, the pressure plate assembly includes an annular plate and several connecting rods distributed on the annular plate. Several sleeves corresponding to the connecting rods are connected to the outer peripheral surface of the drilling host. The upper end of the connecting rod is slidably mounted on the sleeve, and a second spring is connected between the top end of the connecting rod and the inner wall of the sleeve. The second spring is a variable pitch spring.

[0012] Furthermore, the bottom of the positioning groove is provided with several support platforms, and the top of the support platform is rotatably provided with a roller. The roller rolls along the Y-axis direction, and the roller is provided with several anti-slip grooves in the X-axis direction.

[0013] Furthermore, the clamping and moving mechanism includes two rotating wheels symmetrically arranged on the left and right sides of the base, and a second motor. The second motor is mounted on the base. Through slots are opened on both the left and right sides of the inner end face of the positioning groove. The two rotating wheels are respectively rotatably mounted in the corresponding through slots. The second motor drives the two rotating wheels to rotate synchronously in opposite directions through a gear set. An arc-shaped block is provided on the rotating wheel. The radius of the arc-shaped block is gradually increased, so that the aluminum material is pushed along the Y-axis direction by the arc-shaped block.

[0014] Furthermore, several symmetrical adjustment slots are evenly spaced on both sides of the positioning slot. A roller is movably connected between two sets of symmetrical adjustment slots. A slide block is slidably connected to the adjustment slot. A return spring is directly connected to the bottom of the adjustment slot at the bottom of the slide block. The side end of the roller is rotatably mounted on the slide block. A connecting shaft is rotatably arranged inside the base. Both ends of the connecting shaft are connected to support rods. A pressure rod is horizontally arranged at the top of the support rod. The pressure rod passes through the inner wall of the base and extends above the positioning slot. A grip is rotatably arranged on the side end of the base. The rotating shaft of the grip is coaxially connected to the connecting shaft, and a ratchet is sleeved on the rotating shaft of the grip. A corresponding pawl assembly is arranged inside the base. An unlocking block is arranged on the outer end of the base to lift the pawl assembly for unlocking.

[0015] The present invention also provides a method for operating an automatic drilling device for aluminum processing, comprising the following steps:

[0016] S1. Connect the fixing component, drilling component and support component into one unit;

[0017] S2. Mark the required drilling points on the aluminum material, then place it into the positioning groove and clamp it using the clamping mechanism.

[0018] S3. Using the vision sensor integrated on the base, the aluminum surface is scanned in its entirety. The image recognition algorithm accurately captures all marked drilling points and transmits the X-axis and Y-axis spatial coordinate information of each point to the main control system of the equipment in real time. The system automatically generates the optimal drilling path planning scheme.

[0019] S4. The X-axis moving mechanism of the control support component slides on the guide frame, driving the base of the drilling component to move laterally in sync. Using the synchronous reverse pushing force of the arc blocks on both sides, the aluminum material moves smoothly along the Y-axis. When the drill bit axis of the drilling host is completely aligned with the target drilling point, the precise positioning of the drilling is completed.

[0020] S5. Start the lead screw drive mechanism of the drilling assembly, drive the fixed base to lower the drilling host; the pressure plate assembly on the outer periphery of the drilling host contacts the surrounding area of ​​the aluminum material drilling point before the drill bit, apply uniform pressure to the aluminum material surface, and achieve surface stabilization before drilling; at the same time, the stabilizing component on the base is squeezed down as the drilling host descends, and closely abuts against the guide frame, further locking the X-axis moving mechanism, and structurally preventing lateral displacement during the drilling process.

[0021] S6. Drive the drill bit to rotate at high speed. The lead screw drive mechanism continuously drives the drilling host to descend slowly and uniformly at a preset speed to complete the drilling of the current marked point.

[0022] S7. After drilling at the current point is completed, the lead screw drive mechanism drives the drilling host to rise, the pressure plate assembly disengages from the aluminum surface, and the stabilizing assembly resets and releases the X-axis lock; the main control system automatically calls the coordinate information of the next drilling point and repeats steps S4-S6 to complete the drilling operation of all marked points.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] This invention adopts a modular and detachable design, and each core component can be quickly assembled and disassembled by connecting knobs. The overall size is small and the weight is light, which can be easily carried by a single person to outdoor construction sites, small processing plants, temporary maintenance sites and other scenarios. It completely breaks the limitation of traditional large drilling equipment that can only be used in fixed workshops, and perfectly adapts to the needs of mobile and small-batch processing.

[0025] This invention utilizes two sets of independent motors to drive corresponding rotating wheels. The gradually changing radius design of the arc-shaped blocks on the rotating wheels achieves a dual effect simultaneously: Firstly, when the left and right rotating wheels within each set rotate in opposite directions, the arc-shaped blocks form a flexible, encircling push against the sides of the aluminum material, completing precise clamping and X-axis positioning of the aluminum. Secondly, by adjusting the speed and direction of the two sets of motors, the differentiated pushing force of the arc-shaped blocks drives the aluminum material to move smoothly and precisely along the Y-axis, achieving integrated control of clamping and movement. The X-axis movement mechanism, through gear and rack meshing transmission and guide wheel guidance, achieves precise horizontal adjustment of the drilling assembly. Combined with the linkage of the main control system and vision sensors, it achieves precise bidirectional positioning along the X and Y axes, effectively avoiding problems such as hole position deviation and insufficient drilling verticality.

[0026] Combining the dual clamping and locking of the Y-axis, the locking of the stabilizing component during X-axis drilling, and the pre-pressurization and stabilization of the pressure plate component, it effectively avoids equipment displacement and local deformation of aluminum material during the drilling process. The drilling position accuracy and hole diameter consistency far exceed those of manual drilling tools, meeting the strict accuracy requirements of small-batch and customized processing.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0038] like Figures 1 to 9 As shown, an automatic drilling device for aluminum processing includes a fixed assembly, a drilling assembly, and a support assembly detachably connected as one unit. The support assembly connects the drilling assembly and the fixed assembly. The drilling assembly includes a drilling host 1, a fixed base 2, a base 3, and a lead screw drive mechanism 4. The drilling assembly is fixedly mounted on the fixed base 2. The lead screw drive mechanism 4 is located on the upper end of the base 3. The fixed base 2 is connected to the movable end of the lead screw drive mechanism 4, thereby driving the drilling host 1 to perform lifting and lowering movements. A pressure plate assembly 5 is provided on the outer circumference of the drilling host 1. The pressure plate assembly 5 applies pressure to the surface of the aluminum material to stabilize it as the drilling host 1 descends. The drilling assembly uses the base 3 as its mounting base. The lead screw drive mechanism 4 is mounted on the upper end of the base 3, and its movable end is connected to the fixed base 2. The rotational movement of the lead screw is converted into the linear lifting and lowering movement of the fixed base 2, thereby driving the drilling host 1 fixed on the fixed base 2 to complete the lifting and lowering action, realizing drilling feed and reset.

[0039] The fixing component includes a base 6 and a clamping and moving mechanism. The top of the base 6 has a positioning groove 7 along its length. The clamping and moving mechanism is respectively provided on both sides of the positioning groove 7. The clamping and moving mechanism is used to clamp the aluminum material and drive it to move along the Y-axis. The support component includes a support frame 8, a guide frame 9, and an X-axis moving mechanism 10. The guide frame 9 is mounted on the top of the support frame 8, and the bottom of the support frame 8 is connected to the base 6. The X-axis moving mechanism 10 is slidably mounted on the guide frame 9, and the base 3 is mounted on it. The base 3 is provided with a stabilizing component. When the drilling host 1 descends, it will squeeze the stabilizing component to move down and abut against the guide frame 9, thereby stabilizing the X-axis moving mechanism 10.

[0040] In this embodiment, a movable groove 11 is provided on the rear side of the top end of the guide frame 9, and a rack 12 is provided at the bottom end of the movable groove 11. The X-axis moving mechanism 10 includes a support base 13 and an adjusting gear 14. The support base 13 is slidably mounted on the guide frame 9, and the adjusting gear 14 is rotatably mounted on the bottom of the support base 13 and extends to mesh with the rack 12, and is driven by a first motor 15 inside the support base 13. The base 3 is detachably mounted on the support base 13. A guide groove 16 is provided on the front side of the top end of the guide frame 9, and guide wheels 17 are provided on both the left and right sides of the bottom of the support base 13. The guide wheels 17 roll within the guide groove 16.

[0041] When the X-axis position of the drilling assembly needs to be adjusted, the first motor 15 is started. The motor output shaft drives the adjusting gear 14 to rotate. Since the adjusting gear 14 meshes with the rack 12 fixed to the guide frame 9, the rotational motion is converted into linear displacement of the support base 13 along the guide frame 9, which in turn drives the base 3 and the drilling assembly mounted on the support base 13 to move synchronously in the X-axis direction. During the process, the guide wheel 17 at the bottom of the support base 13 rolls synchronously in the guide groove 16. On the one hand, this helps the support base 13 maintain a horizontal posture and avoids tilting or jamming during displacement. On the other hand, it reduces the frictional resistance between the support base 13 and the guide frame 9, improving the stability and smoothness of the X-axis movement.

[0042] In this embodiment, the stabilizing component includes a stabilizing rod 18 and a stabilizing block 19 disposed at the bottom end of the stabilizing rod 18. A sliding hole 20 is provided in the middle of the front side of the base 3, and a corresponding through-hole 21 is provided on the support seat 13, with the through-hole 21 extending through to the guide groove 16. The stabilizing rod 18 is slidably mounted on the sliding hole 20, and the upper part of the stabilizing rod 18 extends through to the top of the base 3. A pressure plate 22 is provided at the top of the stabilizing rod 18, and the pressure plate 22 is located below the fixed seat 2. A first spring 23 is connected between the pressure plate 22 and the base 3. The first spring 23 is a variable pitch spring, which will press down on the stabilizing rod 18 to move down first when the fixed seat 2 descends.

[0043] The variable pitch spring has a large initial pitch and a small elastic coefficient, which allows the stabilizing rod 18 to move down quickly, causing the stabilizing block 19 to quickly fit into the guide frame 9. As the main unit continues to descend, the spring is further compressed to a closer pitch range, increasing the elastic coefficient and generating a stronger reverse elastic force, which tightly presses the stabilizing block 19 against the surface of the guide frame 9, enhancing the locking effect of the X-axis moving mechanism 10 and effectively resisting the impact of drilling vibration.

[0044] When the drilling host 1 descends, the fixed base 2 simultaneously presses down on the pressure plate 22 of the stabilizing component, causing the stabilizing rod 18 to move downward along the sliding hole 20 of the base 3. The stabilizing block 19 at the bottom of the stabilizing rod 18 passes through the through-hole 21 of the support base 13 and abuts against the guide frame 9. The abutting force restricts the displacement of the support base 13, temporarily locking the X-axis moving mechanism 10 and preventing the drilling component from shifting due to vibration during drilling. After drilling is completed, the host rises, the pressure of the fixed base 2 on the pressure plate 22 disappears, the variable pitch first spring 23 drives the stabilizing rod 18 to reset, the stabilizing block 19 separates from the guide frame 9, and the X-axis moving mechanism 10 is unlocked.

[0045] In this embodiment, the base 3 and the support frame 8 are each threaded with a number of connecting knobs 24, and the support 13 and the base 6 are each provided with matching threaded holes, so that the threaded rod on the connecting knob 24 can be screwed into the threaded hole by rotating it to achieve connection.

[0046] The base 3 and support 13, and the support frame 8 and base 6 are all detachably connected via a connecting knob 24. When the connecting knob 24 is rotated, its threaded rod is screwed into the threaded hole of the corresponding component, thus fixing the structure; rotating the connecting knob 24 in the opposite direction will release the fixation, facilitating the individual disassembly and handling of each component and improving the versatility and ease of maintenance of the equipment.

[0047] In this embodiment, the pressure plate assembly 5 includes an annular plate 25 and a plurality of connecting rods 26 distributed on the annular plate 25. The outer peripheral surface of the drilling host 1 is connected to a plurality of sleeves 27 corresponding to the connecting rods 26. The upper end of the connecting rod 26 is slidably mounted on the sleeve 27, and a second spring 28 is connected between the top end of the connecting rod 26 and the inner wall of the sleeve 27. The second spring 28 is a variable pitch spring.

[0048] In this embodiment, a plurality of support platforms 29 are distributed at the bottom end of the positioning groove 7, and a roller 30 is rotatably provided at the top end of the support platform 29. The roller 30 rolls along the Y-axis direction, and a plurality of anti-slip grooves 31 in the X-axis direction are provided on the roller 30. The roller 30 is made of rubber material.

[0049] In this embodiment, the clamping and moving mechanism includes two rotating wheels 32 symmetrically arranged on the left and right sides of the base 6 and a second motor 33. The second motor 33 is mounted on the base 6. Through slots 34 are opened on both the left and right sides of the inner end face of the positioning groove 7. The two rotating wheels 32 are respectively rotatably mounted in the corresponding through slots 34. The second motor 33 drives the two rotating wheels 32 to rotate synchronously in opposite directions through a gear set. An arc-shaped block 35 is provided on the rotating wheel 32. The radius of the arc-shaped block 35 is gradually increased, so that the aluminum material is pushed to move along the Y-axis direction by the arc-shaped block 35.

[0050] Four rotating wheels 32 are set up, divided into front and rear groups. Each group contains two symmetrical rotating wheels 32, and each group is driven by an independent motor. The front motor drives the front left and right rotating wheels 32 to rotate synchronously in opposite directions through a gear set, and the rear motor independently drives the rear left and right rotating wheels 32 to rotate synchronously in opposite directions. During the initial clamping, the small radius ends of the arc blocks 35 on both sides of each group are in contact with the corresponding side of the aluminum material. As the rotating wheels 32 continue to rotate, the large radius ends of the arc blocks 35 on both sides of each group gradually push against the side of the aluminum material. Through the bidirectional lateral clamping force of the arc blocks 35 on the front and rear ends of the aluminum material, a closed clamping effect is formed. If the aluminum material tilts after being loaded, the front or rear motor can be controlled to operate independently to correct the posture of the aluminum material and ensure its straightness. After reaching the position, the corresponding motor stops, and the arc blocks 35 of the front and rear groups maintain the clamping state at the same time. The anti-slip grooves 31 of the rollers 30 achieve Y-axis locking.

[0051] After the aluminum material is securely clamped, displacement along the Y-axis is achieved by coordinating the operation of the two sets of motors. When it is necessary to move the aluminum material along the positive Y-axis, the two sets of motors synchronously drive the rotating wheels 32 in their respective sets to rotate in opposite directions, causing the radius of the arc-shaped block 35 on one side of each set to gradually increase while the radius on the other side decreases synchronously. By utilizing the differentiated pushing force of the arc-shaped blocks 35 on the sides of the aluminum material, a driving force along the positive Y-axis is formed.

[0052] In this embodiment, several symmetrical adjustment grooves 36 are equally spaced on both sides of the positioning groove 7. A roller 37 is movably connected between two sets of symmetrical adjustment grooves 36. A slide block 38 is slidably connected to the adjustment groove 36. A return spring 39 is directly connected to the bottom of the adjustment groove 36 at the bottom end of the slide block 38. The side end of the roller 37 is rotatably mounted on the slide block 38. A connecting shaft 40 is rotatably arranged inside the base 6. Both ends of the connecting shaft 40 are connected to support rods 41. A pressure rod 42 is horizontally arranged at the top end of the support rod 41. The pressure rod 42 penetrates the inner wall of the base 6 and extends above the positioning groove 7. A gripping rod 43 is rotatably arranged on the side end of the base 6. The rotating shaft of the gripping rod 43 is coaxially connected to the connecting shaft 40, and a ratchet 44 is sleeved on the rotating shaft of the gripping rod 43. A corresponding pawl assembly is arranged inside the base 6. An unlocking block is arranged on the outer end of the base 6 to lift the pawl assembly for unlocking.

[0053] The roller 37 assembly within the positioning groove 7 facilitates aluminum material loading. During loading, the aluminum material is pushed into the positioning groove 7 along the Y-axis. The roller 37 remains raised through the cooperation of the slide 38 and the return spring 39, reducing frictional resistance during aluminum material loading. After loading is complete, the lever 43 on the side of the base 6 is moved. The lever 43 drives the support rod 41 through the coaxially connected connecting shaft 40, causing the pressure rod 42 to press down on the upper surface of the aluminum material. Under pressure, the aluminum material simultaneously presses down on the roller 37, and the slide 38 compresses the return spring 39, moving it downwards until the lower surface of the aluminum material is in contact with the support platform 29. At this point, the aluminum material is prevented from easily moving in the Y-axis direction by the anti-slip groove 31.

[0054] The ratchet 44 on the pivot of the lever 43 works with the pawl assembly inside the base 6 to lock the pressure lever 42 in the pressed state, ensuring that the aluminum material is positioned stably. When unlocking, the pawl assembly is lifted by the unlocking block on the outside of the base 6, and the return spring 39 drives the roller 37 and the slide 38 to rise, making it easier to unload the aluminum material.

[0055] The working method of this embodiment is as follows:

[0056] S1. The support assembly is locked to the base 6 of the fixing assembly via the connecting knob 24, and the drilling assembly is installed on the support seat 13 of the support assembly via the connecting knob 24.

[0057] S2. The aluminum material is pushed into the X-axis direction from one end of the positioning groove 7. The roller 37 in the positioning groove 7 is in a high position under the action of the return spring 39, and rolls in contact with the upper surface of the aluminum material to reduce the pushing resistance until the aluminum material moves to the preset initial position. First, the second motor 33 is started at the same time to drive the arc block 35 to rotate slightly and press against the side of the aluminum material, thereby pushing the aluminum material to the middle position and clamping it. Then, the lever 43 is pulled, and the connecting shaft 40 drives the support rod 41 and the pressure rod 42 to press down on the upper surface of the aluminum material. The aluminum material presses down on the roller 37 at the same time to move it down until the lower surface of the aluminum material is completely in contact with the roller 30 of the support platform 29. At this time, the anti-slip groove 31 on the roller 30 abuts against the lower surface of the aluminum material, locking the X-axis position of the aluminum material and preventing it from sliding.

[0058] S3. Using the vision sensor integrated on the base 6, the entire surface of the aluminum material is scanned, and the image recognition algorithm accurately captures all marked drilling points.

[0059] S4. After drilling is ready, the clamping and moving mechanism is started again. The second motor 33 drives the rotating wheels 32 on the left and right sides to rotate synchronously in opposite directions through the gear set. The differential pushing action of the arc blocks 35 on the front and rear sides with gradually changing radii drives the aluminum material to move along the Y-axis (for example, after starting, the front arc block 35 pushes and the rear side makes way, driving the aluminum material to move along the rear side of the Y-axis).

[0060] S5. Start the first motor 15, drive the adjusting gear 14 to mesh with the rack 12 of the guide frame 9, drive the support seat 13 to slide along the guide frame 9, and guide the guide wheel 17 to roll and guide in the guide groove 16, so that the drilling host 1 moves laterally to the X-axis position corresponding to the drilling point; turn off the first motor 15 to complete the X-axis position positioning.

[0061] S6. The drill bit rotates at high speed; the lead screw drive mechanism 4 drives the drilling host 1 to descend slowly and uniformly to complete the drilling at the current point; during the drilling process, the annular plate 25 maintains the pre-pressure state, the arc block 35, the roller 30 and the anti-slip groove 31 maintain the Y-axis lock, and the stabilizing component locks the X-axis to avoid displacement and vibration.

[0062] S7. Finally, all drilling operations are completed by repeating steps S4-S6.

[0063] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

6. The working method of the automatic drilling equipment for aluminum processing according to claim 1, characterized in that, Includes the following steps: S1. Connect the fixing component, drilling component and support component into one unit; S2. Mark the required drilling points on the aluminum material, then place it into the positioning groove. Start the second motor of the clamping and moving mechanism, and drive the rotating wheels on the left and right sides of the positioning groove to rotate in opposite directions through the gear set transmission, thereby clamping the aluminum material on both sides. S3. Using the vision sensor integrated on the base, the aluminum surface is scanned in its entirety. The image recognition algorithm accurately captures all marked drilling points and transmits the X-axis and Y-axis spatial coordinate information of each point to the main control system of the equipment in real time. The system automatically generates the optimal drilling path planning scheme. S4. The X-axis moving mechanism of the control support component slides on the guide frame, driving the base of the drilling component to move laterally in sync. Using the synchronous reverse pushing force of the arc blocks on both sides, the aluminum material moves smoothly along the Y-axis. When the drill bit axis of the drilling host is completely aligned with the target drilling point, the precise positioning of the drilling is completed. S5. Start the screw drive mechanism of the drilling assembly, drive the fixed base to lower the drilling host; the pressure plate assembly on the outer periphery of the drilling host contacts the surrounding area of ​​the aluminum material drilling point before the drill bit, apply uniform pressure to the aluminum material surface, and achieve surface stabilization before drilling; at the same time, the stabilizing component on the base is squeezed down as the drilling host descends, and closely abuts against the guide frame, further locking the X-axis moving mechanism, and structurally preventing lateral displacement during the drilling process; S6. Drive the drill bit to rotate at high speed. The lead screw drive mechanism continuously drives the drilling host to descend slowly and uniformly at a preset speed to complete the drilling of the current marked point. S7. After drilling at the current point is completed, the lead screw drive mechanism drives the drilling host to rise, the pressure plate assembly disengages from the aluminum surface, and the stabilizing assembly resets and releases the X-axis lock; the main control system automatically calls the coordinate information of the next drilling point and repeats steps S4-S6 to complete the drilling operation of all marked points.
