Description

Technical Field

[0001] This invention relates to the field of aircraft parts processing technology, specifically to an integrated processing device for multi-station punching and trimming of aircraft meal boards. Background Technology

[0002] The punching operation in aircraft meal board processing mainly involves punching mounting holes, positioning holes, and assembly slots on the aluminum alloy substrate of the aircraft meal board. Before the operation, the program is compiled, the mold is selected, and the equipment parameters are adjusted according to the drawings. After the sheet is accurately positioned and clamped, the hole is formed by the shearing action of the punch and the die. The punching waste is discharged from under the die. During the processing, the punching gap must be controlled to avoid defects such as aluminum plate sticking to the knife, hole edge turning, and burrs. After punching, the hole size and hole wall smoothness are inspected to ensure that the hole tolerance and edge quality meet the assembly requirements of aerospace parts, providing a qualified opening foundation for subsequent bending and assembly. In the existing technical field, current aircraft meal board punching and trimming processing technology generally adopts a split-process operation mode, with loading, punching, grinding, and unloading processes being independent of each other. The processing relies on manual transfer and workpiece attitude calibration, resulting in poor process continuity, low overall automation, and problems such as misalignment of workstations, workpiece conveying deviation, and insufficient clamping and positioning accuracy. This leads to processing quality defects such as large hole position deviation, uneven hole wall roughness, many burr residues at the hole opening, and easy bumping and deformation of the sheet material. At the same time, traditional grinding methods can only achieve grinding operations inside or outside the hole in one direction, and cannot simultaneously adapt to the fine trimming requirements of the inner and outer walls of the hole and the end faces at both ends. There are many grinding dead corners and poor trimming consistency, which cannot meet the requirements of high-precision, high-consistency, and high-stability large-scale processing and production of aerospace parts.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. The equipment uses a linear translation module to move the limiting frame to the loading station. The second linear lifting module then lifts the support frame to load the sheet metal layer by layer. The first linear lifting module and the telescopic module work together to adjust the electric suction cup to complete workpiece alignment, negative pressure adsorption, and lateral transfer. The workpiece is placed on the second conveyor belt and then conveyed to the first conveyor belt via a correction mechanism. After the workpiece is in place, the positioning module is triggered to complete the limit correction. The transfer robotic arm adsorbs and grabs the workpiece and transfers it to the mold station of the processing mechanism. Subsequently, the linear movement module drives the clamping mechanism to align the workpiece. The second electric telescopic rod adjusts the height of the clamping module and clamps and fixes the workpiece. The first electric telescopic rod drives the punching module to descend and complete the precise punching operation on the sheet metal. Punching waste directly passes through the mold station and falls into the collection hopper for centralized collection. After punching is completed, each mechanism resets sequentially. The clamped workpiece moves backward along with the slide rail lifting platform and is transferred to the grinding station between the upper and lower grinding components.

[0015] 2. After the workpiece is in place, the inner hole grinding operation is carried out first. The third electric telescopic rod drives the mounting plate to move along the guide frame of the limiting frame, causing the inner hole grinding roller to extend from the receiving groove and into the workpiece hole. The first motor, in conjunction with the first belt assembly, drives the grinding roller to rotate at high speed to polish the inner wall of the hole. After the inner hole grinding is completed, the inner hole grinding roller retracts and resets. The second motor drives the first groove drum and the first mounting plate to rotate through the second belt assembly. Relying on the adaptive hinged torque transmission pair composed of the connecting rod and the connecting rod frame, the rotational torque is continuously transmitted to the second mounting plate and... The second groove drum drives the receiving groove to rotate at high speed. At the same time, the third motor drives the gear and rack assembly to move the slider along the dovetail groove seat axially, so that the second groove drum is fed axially with the second mounting plate. During the process, the linkage mechanism compensates for the change in axial distance between the two mounting plates through adaptive swing angle, and maintains continuous torque transmission. This allows the end face of the high-speed rotating receiving groove to fit against the outside of the workpiece hole to complete the burr trimming and end face flattening. The upper and lower grinding components work in sync to complete the integrated processing of both ends of the workpiece hole, realizing the complete shaping and grinding process of the inner and outer walls of the hole after punching.

[0016] In summary, this invention achieves fully automated closed-loop operation of the entire process—workpiece loading, precise positioning, punching and forming, adaptive internal and external hole grinding, double-sided trimming, and automatic unloading—through an integrated processing logic. By adopting a collaborative processing motion mode with adaptive spacing compensation, it achieves complete decoupling of rotary grinding motion and axial feed motion. This allows for the continuous and stable transmission of rotational power while simultaneously completing fine polishing of the inner wall of the hole and double-sided deburring and trimming of the hole end face. This eliminates grinding dead angles in traditional processing, significantly improving the overall accuracy, processing stability, and batch production efficiency of punching and trimming of aircraft meal boards. It fully adapts to the high-precision, standardized, and large-scale processing and production needs of aerospace sheet materials. Attached Figure Description

[0024] The specific work steps are as follows: Step 1: The operator neatly stacks the batch of aircraft meal board materials to be processed inside the limit frame 315 in advance to complete the pre-processing work for loading. Then, the operator controls the control console 1 to start the built-in automated preset processing program, and synchronously drives the linear translation module 314, the second linear lifting module 311, the first linear lifting module 36, the telescopic module 39, the electric suction cup 310, the belt moving module 38, the second conveyor belt 35, the sensor 33, the first conveyor belt 32, the positioning module 34 and the transfer robotic arm 2 to start working together. Step 2: The linear translation module 314 drives the limiting frame 315 carrying the plate to move in the front and back direction, and delivers the storage workpiece to the working area directly below the bracket 312. The second linear lifting module 311 vertically lifts the bracket 312, so that the bracket 312 fits against the bottom of the limiting frame 315 and pushes the stacked plates to be processed upward, so that the plates are lifted layer by layer along the inner limiting space of the limiting frame 315 and transported to the gripping and handling station directly below the electric suction cup 310, completing the preparation for plate loading and alignment. Step 3: The first linear lifting module 36 drives the lead screw to rotate through the built-in motor. Relying on the lead screw and nut transmission structure, it drives the top moving end and the fixed mounting bracket 37 to descend vertically as a whole, realizing the alignment and calibration of the bottom electric suction cup 310 and the top plate to be processed. After alignment, the telescopic module 39 extends downward and pushes the electric suction cup 310 to adhere to the upper surface of the plate. The electric suction cup 310 activates the negative pressure adsorption function to adsorb and fix a single plate to be processed, realizing stable gripping of the plate. After gripping, the belt moving module 38 drives the belt to operate in a closed loop through the motor, driving the telescopic module 39, electric suction cup 310 and the adsorbed and fixed plate to move horizontally to the left in sync, and move the plate to the conveying station above the second conveyor belt 35. Step 4: The telescopic module 39 extends downward slightly again, placing the sheet material on the conveying end surface of the second conveyor belt 35. The electric suction cup 310 releases the negative pressure adsorption, completing the unloading and loading of the sheet material. Subsequently, the second conveyor belt 35 starts horizontal conveying operation, driving the sheet material to move at a uniform speed from right to left. At the same time, relying on the built-in correction roller of the second conveyor belt 35, the sheet material's posture is automatically corrected and its position is calibrated, accurately conveying the sheet material to the feeding end of the first conveyor belt 32. Step 5: The first conveyor belt 32 continues to transport the plate horizontally to the left. When the plate moves to the designated detection position and triggers the sensor 33 to sense the signal, the plate arrives at the positioning station. The front and rear positioning modules 34 receive the command from the control console 1 and extend inward synchronously to clamp and position the plate from the front and rear sides. After positioning is completed, the transfer robot arm 2 receives the signal to start the operation and drives the end suction cup execution end to move to the upper surface of the plate at the positioning station. It uses negative pressure to pick up the plate after positioning. Then the front and rear positioning modules 34 retract and reset synchronously, releasing the clamping limit on the plate and completing the automated feeding process. Step 6: After the transfer robotic arm 2 picks up the positioned airplane meal board, it sequentially transfers the board to the upper surface of the mold station 57 of the two processing mechanisms 5 arranged symmetrically in front and behind according to the preset program, so that the board can be stably attached to the processing reference surface of the mold station 57 to complete the punching preparation. The control console 1 continues to run the preset processing program and synchronously controls the linear movement module 58, the second electric telescopic rod 512, the clamping module 511, the first electric telescopic rod 54, the punching module 55 and the rotation module 59 to start in linkage. Step 7: The linear motion module 58 drives the rotating module 59 mounted on the top and the slide rail lifting platform 510 to move inward to the rear working position of the mold station 57. The second electric telescopic rod 512 drives the clamping module 511 through the telescopic action, so that the clamping module 511 completes the height adjustment under the vertical limiting guide of the slide rail lifting platform 510 and aligns with the plate to be processed on the surface of the mold station 57. The clamping module 511 starts the clamping action to complete the stable clamping and fixing from the side of the plate, lock the plate processing posture, and avoid displacement deviation during punching. Step 8: After the sheet metal is fixed, the two sets of first electric telescopic rods 54 extend and retract synchronously, driving the lifting end of the guide rail lifting platform 53 to lift the bottom embedded punching module 55, adjusting the punching module 55 to the preset punching height above the sheet metal. Then the punching module 55 starts working, punching the aircraft meal board sheet metal according to the preset hole diameter and hole position parameters. The waste and scrap generated by the punching operation can penetrate the pre-made mold hole inside the mold station 57 and fall naturally to the feed port of the collection trough 56 below. The waste is collected by the collection trough 56, realizing the centralized treatment of punching waste. After the punching operation is completed, the first electric telescopic rod 54 retracts and resets, driving the punching module 55 to move vertically upward and away from the sheet metal processing area, completing the reset of the punching mechanism. Step 9: The linear motion module 58 reverses the rotation module 59 and the slide rail lifting platform 510 to move outwards as a whole, which drives the clamping module 511 and the clamped and fixed punched plate to move synchronously to the designated flipping station. The rotation module 59 starts to rotate, driving the slide rail lifting platform 510 to flip 180 degrees as a whole, so that the punched plate clamped by the clamping module 511 changes its posture and is transferred to the grinding station between the upper and lower grinding components 6. Step 10: After the plate posture is switched to the correct position, the control console 1 calls the grinding and trimming processing program, and controls the third electric telescopic rod 65, the first motor 69, the second motor 614 and the third motor 625 to start in coordination, and complete the grinding of the inner hole of the workpiece and the trimming and deburring of the outer edge of the hole in sequence. Step 11: In the inner hole grinding process, the third electric telescopic rod 65 extends forward, pushing the mounting plate 64 to move smoothly inward under the vertical limiting constraint of the mounting frames 62 on both sides. Simultaneously, it drives the transmission shaft seat 66, the connecting shaft 67 and the inner hole grinding roller 68 to move axially as a whole. This causes the connecting shaft 67 to slide inward along the hollow inner cavity of the first groove rotating cylinder 613 and the second groove rotating cylinder 620, driving the inner hole grinding roller 68 stored in the storage groove 624 to extend outward and into the inner cavity of the hole formed by punching the plate. At the same time, the first motor 69 starts running and transmits power to the transmission shaft seat 66 through the belt drive structure of the first belt assembly 610, driving the transmission shaft seat 66, the connecting shaft 67 and the inner hole grinding roller 68 to rotate at high speed. The high-speed rotating inner hole grinding roller 68 fully contacts and rubs against the inner wall of the hole, polishing the rough hole wall after punching in all directions, eliminating the tool marks, burrs and uneven defects of the hole wall. Step 12: After the inner hole grinding operation is completed, the third electric telescopic rod 65 retracts and resets, driving the inner hole grinding roller 68 to axially retract and retract into the middle of the inner cavity of the receiving groove 624, completing the reset of the inner hole grinding mechanism. Then, the outer edge trimming process of the hole opening is started. The second motor 614 outputs rotational power through the transmission structure of the second belt assembly 615, driving the first groove drum 613 to rotate at high speed. The first groove drum 613 drives the coaxially fixed first mounting plate 616 to rotate synchronously. The first mounting plate 616 and the second mounting plate 621 are connected by two sets of symmetrically arranged connecting rods 617 and connecting rod frame 622, forming an adaptively compensated circumferential torque transmission pair. Relying on the angle adaptive adjustment characteristics of the hinge structure, the rotational torque of the first mounting plate 616 can be transmitted to the second mounting plate 621 without interruption or loss, thereby driving the second groove drum 620 and the external outer hole grinding roller 623 to rotate synchronously at high speed, providing a stable rotation condition for outer hole grinding. While the outer hole grinding roller 623 continues to rotate at high speed, the third motor 625 starts to drive the gear and rack assembly 626 to operate. The gear rotates and meshes to drive the rack to make precise linear axial displacement. The rack drives the slider 619 to slide inward along the guide trajectory of the dovetail groove seat 618. The slider 619 simultaneously pushes the second groove drum 620 and the second mounting plate 621 to feed inward as a whole, so that the relative axial distance between the second mounting plate 621 and the first mounting plate 616 changes. During the process, the two sets of connecting rods 617 and connecting rod frame 622 adaptively deflect the swing angle through the hinge pair to compensate for the axial distance change between the two mounting plates, thereby maintaining a stable hinge transmission relationship and ensuring that the rotational torque transmission is uninterrupted. This achieves decoupling and coordination between rotational motion and axial feed motion. The end face of the high-speed rotating and axially feeding outer hole grinding roller 623 is in close contact with the outer edge of the hole in the plate, and uniformly grinds and smooths the burrs, sharp edges, and flange defects of the hole after punching, completing the edge trimming operation of the hole. Step 13: The two sets of grinding components 6, symmetrically arranged on the upper and lower parts of the equipment, alternately repeat the inner hole grinding and outer edge trimming processes of Step 11 and Step 12 above, respectively to perform all-round fine processing on the upper and lower ends of the hole in the plate, eliminating various appearance and precision defects after punching and forming. After all the processing steps of the plate are completed, the rotating module 59 starts the rotation adjustment again, driving the slide rail lifting platform 510 to finely adjust the angle and posture, so that the finished plate clamped and fixed by the clamping module 511 faces the gripping operation area of ​​the transfer robot arm 2. The linear movement module 58 drives the rotating module 59 to move inward as a whole, transferring the finished plate to the preset gripping position of the transfer robot arm 2. After receiving the positioning signal, the transfer robot arm 2 uses the end suction cup structure to adsorb and grip the finished plate after processing, and then smoothly transfers and places the plate on the surface of the feed end of the third conveyor belt 44 of the unloading mechanism 4, completing the transfer from the finished processing position to the unloading position. Step 14: The control console 1 starts the material feeding and conveying program, and synchronously controls the third linear lifting module 42, the third conveyor belt 44, the transfer conveyor belt 43, and the fourth conveyor belt 45 to work together. The third linear lifting module 42 drives the screw screw to rotate through the built-in motor, which drives the screw nut and the transfer conveyor belt 43 mounted on the top to be vertically lifted as a whole, so that the conveying plane of the transfer conveyor belt 43 is aligned with the conveying plane of the third conveyor belt 44 at the same height. After the alignment is completed, the third conveyor belt 44 starts to run, driving the finished sheet material to be horizontally conveyed from right to left to be transferred to the surface of the transfer conveyor belt 43. Step 15: Subsequently, the third linear lifting module 42 reverses the drive screw, causing the transfer conveyor belt 43 and the finished product sheet to descend vertically as a whole, so that the transfer conveyor belt 43 and the fourth conveyor belt 45 below are aligned at the same height. After alignment, the transfer conveyor belt 43 starts conveying, transferring the finished product sheet to the feeding end of the fourth conveyor belt 45. Finally, the fourth conveyor belt 45 continues to convey to the left, transporting the finished product sheet to the finished product collection area at the discharge end of the equipment. The staff collects and stacks the finished airplane meal boards at the discharge end, completing the entire process of processing a single batch of boards. The collected finished products can be transferred to the subsequent processes.
