[0018] 4. The linear motor drives the drill bit shank to move longitudinally, allowing for flexible adjustment of the drilling depth; the meshing transmission between the drive gear and pinion II enables the drill bit body to rotate at high speed. Combined with the 45° chamfer design of the support bracket, it is easy to push the support bracket to the bottom of the fixed seat for support, which not only enhances structural stability but also avoids interference with the movement of other components.
[0019] 5. The drill bit assembly adopts an independent modular design, which can be quickly replaced when damaged; the lifting cylinder adjusts the overall height through the support column to adapt to the processing of sliding doors of different thicknesses, reducing the complexity of equipment adjustment.
[0020] 6. The side motor, drilling motor and linear motor are coordinated by the control system to realize a fully automated drilling process, reduce manual intervention and optimize energy consumption, making it suitable for mass production scenarios. Attached Figure Description

The cylinder clamping plate 33 adopts a double-acting booster cylinder (output pressure adjustable from 0.6-1.2MPa). The clamping surface is inlaid with polyurethane anti-slip pads (Shore hardness 80A) to ensure clamping force and prevent surface scratches. A waste material conveying assembly 2 is fixedly installed on the front side of the top of the frame 1, below the support frame 31.

The noise level is reduced to below 68dB. The cover 41 is fixedly installed on the rear side of the top of the frame 1. The inside of the cover 41 is equipped with a multi-angle cutter 42. The saw blade angle of the multi-angle cutter 42 is adjustable (-45° to 90°), supporting various processes such as beveling and straight cutting to meet the installation requirements of sliding door guide rails. Drilling assemblies 5 are fixedly installed on the surface of the cover 41 and the top of the frame 1. The drilling assembly 5 includes an adjusting cylinder 51, which is fixedly installed on the surface of the cover 41 and the top of the frame 1 respectively. A top pressure cylinder 52 is fixedly installed on the telescopic end of the adjusting cylinder 51. The telescopic ends of the upper and lower sets of top pressure cylinders 52 are respectively fixedly installed with an upper drilling machine 53 and a lower drilling machine 54. The dual drilling machines are independently controlled by the top pressure cylinders 52 and can drill holes (such as pulley mounting holes and handle holes) on the upper and lower surfaces of the sliding door at the same time, increasing efficiency by 50%. The upper drilling machine 53 and the lower drilling machine 54 adopt servo electric spindles (maximum speed 30,000 rpm) and are equipped with an automatic tool changer (tool magazine capacity of 6 tools) to support the processing of different hole diameters.
[0033] The frame 1 is made of high-strength alloy steel welded frame, with an internal cross-shaped reinforcing rib structure, increasing the static load capacity to 2000kg;
[0034] The bottom is equipped with adjustable shock-absorbing feet (height adjustment range ±15mm) to adapt to uneven workshop floors;
[0035] The worktable surface is precision ground to a flatness of ≤0.02mm / m;
[0036] A longitudinal slide block 37 is fixedly installed on the left side of the top of the limiting base plate 34. A slide plate 35 is slidably installed on the surface of the longitudinal slide block 37. A push cylinder 36 is fixedly installed on the left side of the slide plate 35.
[0037] A transverse slide 38 is fixedly installed on the front side of the top of the support frame 31. The transverse slide 38 adopts a linear guide rail (repeat positioning accuracy ±0.005mm). The limiting base plate 34 is slidably installed on the top of the transverse slide 38. The longitudinal slide 37 cooperates with the transverse slide 38 to realize bidirectional micro-adjustment of the workpiece in front and behind and left and right, and adapt to sliding doors of different sizes (width 400~1200mm).
[0038] A toothed plate 311 is fixedly installed on the front side of the support frame 31. A positioning plate 312 is slidably installed on the front side of the support frame 31 and at the toothed plate 311. The positioning plate 312 is equipped with a laser scale (resolution 0.01mm) for easy manual verification. A servo motor 39 is fixedly installed at the bottom of the positioning plate 312. A gear 310 that meshes with the toothed plate 311 is fixedly installed on the output shaft of the servo motor 39. The servo motor 39 drives the positioning plate 312 to move, and the positioning accuracy reaches ±0.05mm, avoiding the vibration problem of traditional cylinder positioning.
[0039] A drive motor 23 is fixedly installed on the rear side of the transmission frame 21. Transmission rollers are rotatably installed on both the left and right sides of the inner cavity of the transmission frame 21 and the inner cavity of the conveyor belt 22. The output shaft of the drive motor 23 is fixedly connected to the transmission rollers.
[0040] The lower drilling machine 54 includes a lifting cylinder 541. A support column 5413 is fixedly connected to the telescopic end of the lifting cylinder 541. A rotating column 546 is rotatably mounted on the top of the support column 5413 via a bearing. A gear ring 544 is fixedly sleeved on the bottom of the surface of the rotating column 546. Six identical positioning slots 5417 are opened on the bottom of the surface of the rotating column 546 above the gear ring 544. A side motor 542 is fixedly mounted on the bottom right side of the support column 5413. A small gear 543 that meshes with the gear ring 544 is fixedly connected to the output shaft of the side motor 542.
[0041] A mounting bracket 5411 is fixedly installed on the top of the front side of the support column 5413. An angle sensor 5410 is fixedly installed on the surface of the mounting bracket 5411. The angle sensor 5410 monitors the rotation angle of the rotating column 546 in real time to ensure accurate drill bit switching position. The detection end of the angle sensor 5410 is connected to the surface of the rotating column 546. A propulsion cylinder 549 is embedded through the top of the surface of the mounting bracket 5411. The output shaft of the propulsion cylinder 549 is fixedly connected to a support bracket 548.
[0042] A positioning column 5412 is fixedly connected to the surface of the support bracket 548 and to the corresponding position of the positioning groove 5417. The rear side of the top of the support bracket 548 is cut at 45°. A drilling motor 5416 is embedded in the center of the top of the rotating column 546. The output shaft of the drilling motor 5416 is fixedly connected to a drive gear 547. Six identical mounting grooves 545 are opened on the outer ring of the top of the rotating column 546. A linear motor 5415 is fixedly connected to the inner wall of the mounting groove 545 longitudinally.
[0043] Each drill bit is equipped with a linear motor 5415, which can individually control the feed depth for fine adjustment (it is necessary to ensure that the pinion 5414 meshes with the drive gear 547) to meet different hole depth requirements, avoid overall mechanism adjustment, improve processing flexibility, and at the same time, other drill bits that do not need to work can be stored in the mounting slot 545 during drilling to avoid obstruction during processing.
[0044] The propulsion cylinder 549 pushes the positioning pin 5412 into the positioning groove 5417, eliminating the error caused by gear transmission clearance and ensuring the repeatability accuracy of the drilling position.
[0045] The linear motor 5415 is directly driven, and compared with the traditional ball screw structure, the linear motor 5415 has a faster response and higher precision, making it suitable for high-frequency drilling operations.
[0046] The drill shank 5420 and drill holder 5419 adopt a modular design, which can be replaced separately when damaged, reducing maintenance costs;
[0047] Mounting slot 545 protects linear motor 5415 and drill bit assembly, preventing chips and coolant from entering and improving equipment reliability;
[0048] The moving end of the linear motor 5415 is fixedly connected to the inner cavity of the mounting groove 545 with a fixed base 5418. The top of the fixed base 5418 is rotatably connected to the drill bit seat 5419 via a bearing. The inner cavity of the drill bit seat 5419 is provided with a drill bit shank 5420. The top of the drill bit shank 5420 is fixedly connected to the drill bit body 5421. The surface of the drill bit seat 5419 is fixedly fitted with a pinion 5414 that meshes with the drive gear 547.
[0049] In use, the workpiece is placed on top of the support plate 32. The cylinder clamping plate 33, in conjunction with the support plate 32, clamps the sliding door in the front-to-back direction. Then, the servo motor 39 drives the gear 310 to rotate, and under its meshing action with the gear plate 311, it drives the positioning plate 312 to move left and right for positioning. At the same time, the limiting base plate 34 moves left and right on multiple transverse slides 38 to adjust the support position. Simultaneously, by pushing the telescopic end of the cylinder 36 to extend and retract, the slide plate 35 is pushed to move back and forth on the longitudinal slide 37, thus adjusting the front and back support in sequence. During cutting, the multi-angle cutting machine 42 is used to cut the workpiece. The saw blade can be adjusted to three angles: -45°, 90°, and 45°, achieving multi-angle cutting effects. During drilling, the upper drilling machine 53 and lower drilling machine 54 are adjusted forward and backward using the adjusting cylinder 51. Then, the upper drilling machine 53 and lower drilling machine 54 are moved up and down by the top pressure cylinder 52. The upper drilling machine 53 and lower drilling machine 54 drill holes in the sliding door in both the upper and lower directions. Waste material from the processing falls onto the conveyor belt 22, which is driven by the drive motor 23 to transport the waste material to the waste area for processing. The machines 54 have the same structure and are arranged symmetrically. When it is necessary to switch drill bits, the side motor 542 drives the pinion 543 to rotate, which in turn drives the gear ring 544 and the rotating column 546 to rotate, so that the target drill bit (installed in a certain mounting slot 545) is aligned with the machining position. The angle sensor 5410 monitors the rotation angle of the rotating column 546 in real time to ensure accurate positioning. The propulsion cylinder 549 pushes the support frame 548 forward, so that the positioning column 5412 is inserted into the corresponding positioning slot 5417, ensuring that the drill bit position is fixed and preventing displacement during machining. At the same time, the support frame 548 is located below the fixed seat 5418 for support. The linear motor 5415 pushes the fixed seat 5418 to move upward along the mounting groove 545, controlling the pinion 5414 at that location to be flush with and mesh with the drive gear 547. The drilling motor 5416 drives the drive gear 547 to rotate, and through meshing with the pinion 5414, drives the drill bit holder 5419 and the drill bit body 5421 to rotate at high speed. If it is necessary to switch to the next drill bit, the push cylinder 549 retracts, causing the positioning pin 5412 to disengage from the positioning groove 5417. The side motor 542 drives the rotating pin 546 to rotate again, switching to the next drill bit. The above steps are repeated to complete the drill bit switching operation.
[0050] In summary, this efficient sliding door drilling and cutting processing device, through the cooperation of the frame 1, waste material conveying component 2, clamping component 3, cutting component 4 and drilling component 5, solves the problem that current sliding door drilling and cutting processing devices usually perform drilling and cutting separately. This method requires frequent transfer of the sliding door workpiece for processing and multiple clamping of the workpiece.
