One device integrates compaction, cutting, and drilling functions, reducing process switching time.

[0018] 4. The linear motor drives the drill shank to move longitudinally, which can flexibly adjust the drilling depth; the meshing transmission between the drive gear and the pinion 2 causes the drill body to rotate at high speed. Combined with the 45° angle design of the support bracket, it is convenient to push the support bracket to the bottom of the fixed seat for support, which not only enhances the structural stability but also avoids interference with the movement of other components.

[0019] 5. The drill bit assembly adopts an independent modular design and 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 and reduce the complexity of equipment adjustment.

[0020] 6. The side motor, drilling motor and linear motor are coordinated by the control system to achieve a fully automated drilling process, reduce manual intervention, and optimize energy consumption, making it suitable for mass production scenarios. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] See also Figures 1-10An efficient sliding door drilling and cutting device includes a frame 1, a clamping assembly 3 is fixedly installed on the front side of the top of the frame 1, and the clamping assembly 3 includes a support frame 31, which is fixedly welded to the top of the frame 1. A limit base plate 34 is fixedly installed on the left side of the top of the support frame 31, a bearing plate 32 is fixedly installed on the top of the support frame 31, and a cylinder clamping plate 33 is fixedly installed on the front side of the top of the bearing plate 32. The cylinder clamping plate 33 adopts a double-acting booster cylinder (the output pressure is adjustable from 0.6 to 1.2 MPa). The clamping surface is inlaid with polyurethane anti-slip pads (Shore hardness 80A), which not only ensures the clamping force but also prevents surface scratches. The front side of the top of the frame 1 and below the support frame 31 is fixedly installed with a waste transmission component 2. The waste transmission component 2 includes a transmission frame 21, which is fixedly installed on the top of the frame 1. The surface of the transmission frame 21 is equipped with a conveyor belt 22. The rear side of the top of the frame 1 is fixedly installed with a cutting component 4. The cutting component 4 includes a cover 41. The inner layer of the cover 41 is equipped with 5mm thick sound-absorbing cotton. The noise is reduced to below 68dB. The cover 41 is fixedly installed on the rear side of the top of the frame 1. A multi-angle cutter 42 is installed inside the cover 41. The saw blade angle of the multi-angle cutter 42 is adjustable (-45° to 90°), supporting various processes such as bevel cutting and straight cutting to meet the installation requirements of the sliding door guide rail. The surface of the cover 41 and the top of the frame 1 are fixedly installed with a drilling assembly 5. 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 pressure cylinder 52 is fixedly mounted on the telescopic end of the adjustment cylinder 51. An upper drilling machine 53 and a lower drilling machine 54 are fixedly mounted on the telescopic ends of the upper and lower sets of pressure cylinders 52, respectively. The dual drilling machines are independently controlled by the pressure cylinders 52 and can simultaneously drill holes (such as pulley mounting holes and handle holes) on the upper and lower surfaces of the sliding door, increasing efficiency by 50%. The upper and lower drilling machines 53 and 54 use servo electric spindles (maximum speed 30,000 rpm) and are equipped with an automatic tool changer (tool magazine capacity of 6 tools) to support machining of different hole diameters.

[0033] Frame 1 adopts high-strength alloy steel welded frame with cross-shaped reinforcement structure added inside, and the static load capacity is increased to 2000kg;

[0034] The bottom is equipped with adjustable shock-absorbing feet (height adjustment range ±15mm) to adapt to uneven workshop floors;

[0035] The work surface is precision ground, with a flatness of ≤0.02mm / m;

[0036] A longitudinal slide 37 is fixedly mounted on the left side of the top of the limiting base plate 34, a slide plate 35 is slidably mounted on the surface of the longitudinal slide 37, and a push cylinder 36 is fixedly mounted 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 (repeat positioning accuracy of ±0.005mm). The limit base 34 is slidably installed on the top of the transverse slide 38. The longitudinal slide 37 cooperates with the transverse slide 38 to achieve fine-tuning of the workpiece in both the front and back and left and right directions, adapting to sliding doors of different sizes (width 400-1200mm);

[0038] A toothed plate 311 is fixedly mounted on the front side of the support frame 31. A positioning plate 312 is slidably mounted on the front side of the support frame 31 and located at the toothed plate 311. The positioning plate 312 is provided with a laser scale (resolution 0.01mm) for easy manual calibration. A servo motor 39 is fixedly mounted on the bottom of the positioning plate 312. A gear 310 meshing with the toothed plate 311 is fixedly mounted on the output shaft of the servo motor 39. The servo motor 39 drives the positioning plate 312 to move, with a positioning accuracy of ±0.05mm, thus avoiding the jitter 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 the left and right sides of the inner cavity of the transmission frame 21 and located in 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. The telescopic end of the lifting cylinder 541 is fixedly connected to a support column 5413. 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 grooves 5417 are formed on the bottom of the surface of the rotating column 546 and located above the gear ring 544. A side motor 542 is fixedly mounted on the bottom of the right side of the support column 5413. The output shaft of the side motor 542 is fixedly connected to a pinion 543 that meshes with the gear ring 544.

[0041] A mounting bracket 5411 is fixedly mounted on the top of the front side of the support column 5413. An angle sensor 5410 is fixedly mounted 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 in the top of the surface of the mounting bracket 5411. The output shaft of the propulsion cylinder 549 is fixedly connected to the support bracket 548.

[0042] A positioning column 5412 is fixedly connected to the surface of the support bracket 548 at a position corresponding to the positioning slot 5417. The rear side of the top of the support bracket 548 is beveled at a 45° angle. 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 the driving gear 547. The outer ring of the top of the rotating column 546 is formed with six identical mounting slots 545. The inner wall of the mounting slot 545 is fixedly connected to the linear motor 5415 in the longitudinal direction.

[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 second pinion 5414 is engaged with the drive gear 547) to meet the requirements of different hole depths, avoid overall mechanism adjustment, and improve processing flexibility. At the same time, during the drilling operation, other drill bits that are not needed can be stored in the installation slot 545 to avoid obstruction during processing.

[0044] The propulsion cylinder 549 pushes the positioning column 5412 into the positioning groove 5417 to eliminate the error caused by the gear transmission gap and ensure the repeatability of the drilling position;

[0045] The linear motor 5415 is directly driven. Compared with the traditional screw structure, the linear motor 5415 has faster response and higher precision, which is suitable for high-frequency drilling operations;

[0046] The drill bit shank 5420 and the drill bit holder 5419 adopt a modular design and can be replaced separately when damaged, thus reducing maintenance costs;

[0047] The mounting groove 545 protects the linear motor 5415 and the drill assembly, preventing the intrusion of chips and coolant, thereby improving the reliability of the equipment;

[0048] The moving end of the linear motor 5415 is fixedly connected to a fixed seat 5418 in the inner cavity of the mounting groove 545. The top of the fixed seat 5418 is rotatably connected to a drill seat 5419 through a bearing. The inner cavity of the drill seat 5419 is provided with a drill shank 5420. The top of the drill shank 5420 is fixedly connected to a drill body 5421. The surface of the drill seat 5419 is fixedly sleeved with a small gear 5414 that meshes with the driving gear 547.

[0049] When in use, the workpiece is placed on the top of the carrier plate 32, and the cylinder clamping plate 33 is used to cooperate with the carrier plate 32 to limit and clamp the sliding door in the front and rear directions. Then, the servo motor 39 is used to drive the gear 310 to rotate, and the positioning plate 312 is driven to move left and right under the meshing action of the gear plate 311. At the same time, the limiting base plate 34 moves left and right on multiple horizontal slides 38 to adjust the support position. At the same time, the slide plate 35 is pushed forward and backward on the longitudinal slide 37 by pushing the telescopic end of the cylinder 36 to extend and retract, and the front and rear support adjustments are performed in turn. When cutting, the multi-angle cutting machine 42 is used to cut the workpiece. The saw blade can be adjusted at three angles of -45° / 90° / 45° to achieve multi-angle cutting effects. When drilling, the upper drilling machine 53 and the lower drilling machine 54 are pushed by the adjusting cylinder 51 to adjust the position in the front and rear directions, and then the upper drilling machine 53 and the lower drilling machine 54 are driven by the top pressure cylinder 52 to move in the up and down directions. The upper drilling machine 53 and the lower drilling machine 54 are used to drill holes in the upper and lower directions of the sliding door. The waste materials in the processing process fall onto the conveyor belt 22, and the drive motor 23 drives the conveyor belt 22 to transmit the waste materials to the waste area for processing. The upper drilling machine 53 and the lower drilling machine 54 are used to drill holes in the upper and lower directions of the sliding door. The structure of the machine 54 is the same and is symmetrically arranged up and down. When the drill bit needs to be switched, the side motor 542 drives the small gear 543 to rotate, driving the ring gear 544 and the rotating column 546 to rotate, so that the target drill bit (installed in a certain installation slot 545) is aligned with the processing 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 bracket 548 forward to insert the positioning column 5412 into the corresponding positioning slot 5417 to ensure that the drill bit position is fixed to prevent deviation during processing. At the same time, the support bracket 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 slot 545, controlling the pinion 2 5414 there to be flush with and meshed with the driving gear 547. The drilling motor 5416 drives the driving gear 547 to rotate, and by meshing with the pinion 2 5414, drives the drill seat 5419 and the drill body 5421 to rotate at high speed. If it is necessary to switch to the next drill bit, the propulsion cylinder 549 is retracted to disengage the positioning column 5412 from the positioning slot 5417. The side motor 542 drives the rotating column 546 to rotate again and switch to the next drill bit. Repeat the above steps for processing to complete the drill bit switching operation.

[0050] To sum up: this efficient sliding door drilling and cutting processing device, through the cooperation of the frame 1, the waste transfer component 2, the clamping component 3, the cutting component 4 and the drilling component 5, solves the problem that the current sliding door drilling and cutting processing device usually performs drilling and cutting separately, which requires frequent transfer of the sliding door workpiece for processing and multiple clamping of the workpiece.
