Description

Technical Field

[0001] The invention relates to the technical field of aircraft component surface polishing, in particular to a polishing device for aircraft component surface treatment. Background Art

[0002] Polishing refers to a processing method that uses mechanical, chemical or electrochemical effects to reduce the surface roughness of a workpiece to obtain a bright and flat surface. It is a modification process on the workpiece surface using polishing tools and abrasive particles or other polishing media. Polishing cannot improve the dimensional accuracy or geometric shape accuracy of the workpiece, but is aimed at obtaining a smooth surface or mirror gloss. Sometimes it is also used to eliminate gloss (matte). Usually, a polishing disc is used as a polishing tool. The polishing disc is generally made of multiple layers of canvas, felt or leather, clamped on both sides by metal discs, and its wheel rim is coated with a polishing agent uniformly mixed with micro-powder abrasives and grease. In the process of polishing the aircraft cabin floor or aircraft cargo hold floor, it is necessary to use a polishing agent to assist the polishing process, and the polishing agent is mostly sprayed separately at the position that needs to be polished through a spray pipe, and cannot be automatically sprayed at the polishing position while the polishing operation is being performed. The polishing agent needs to be separately controlled and used in conjunction with it, which is not convenient for the polishing operation and has a low degree of automation. The spraying pipe cannot spray synchronously with the use of the polishing disc. When the polishing disc stops using, the spraying pipe cannot stop spraying synchronously, and the process of spraying the polishing agent by the spraying pipe is continuous spraying, which cannot achieve the purpose of controlling the material discharge, and will cause waste of the polishing agent and increase the polishing cost. Secondly, in order to make the polishing more full and delicate, it is necessary to improve the planning of the polishing route.

During the descent of the lifting plate 103, the third rotating motor 201 stops working. The rotating motor 504 rotates, the third rotating motor 504 rotates to drive the rotating shaft 505 to rotate, the rotating shaft 505 rotates to drive the third gear 506 to rotate, the third gear 506 rotates on the first gear ring 503 to drive the rotating frame 502 to rotate, the rotating frame 502 rotates to drive the polishing disc 7 to rotate, and the aircraft cabin floor is polished by the rotation of the polishing disc 7.

The polishing liquid flows back to the material discharge bin through the recovery bin for polishing. The purpose of controlling the material discharge is achieved by overlapping and misaligning 513 and the discharge notch 512, and the displacement of the polishing agent during the polishing process is controlled to reduce the waste of the polishing agent. When the polishing disc 7 contacts the aircraft cabin floor, the movable pin 517 moves upward under the pressure, and the movable pin 517 moves upward to shrink the telescopic frame 515. The bottom end of the movable pin 517 is rotatably installed with a ball, and the ball can contact and roll with the aircraft cabin floor.The telescopic frame 515 is extended and retracted to squeeze and contract the internal spring 516, and the movable pin 517 moves upward to expose the liquid outlet groove covered at the end, and the polishing liquid in the lower material bin is discharged from the liquid outlet groove to the outside through the discharge frame 514 for auxiliary polishing, so that the polishing device and the spraying device are integrated and automated, and then the second rotating motor 402 is controlled to be turned on, and the second rotating motor 402 rotates to drive the turntable 403 to rotate, and the rotation of the turntable 403 drives the rotating rod 404 to perform reciprocating circular rotation, and the reciprocating circular rotation of the rotating rod 404 drives the moving block 405 to reciprocate on the fixed plate 406, and the reciprocating movement of the moving block 405 drives the reciprocating rod 407 to reciprocate, and the reciprocating movement of the reciprocating rod 407 drives the threaded second gear 408 to perform forward and reverse reciprocating rotation, and the second gear 408 performs forward and reverse reciprocating rotation on the second rack 409, driving the T-block 410 to reciprocate laterally, and the T-block 410 reciprocates laterally The polishing mechanism 5 is driven to move back and forth horizontally, and at the same time, the second rotating motor 402 rotates and drives the connecting shaft 303 to rotate through the synchronous wheel transmission group 302. The connecting shaft 303 rotates and drives the first gear 304 to rotate. The first gear 304 rotates on the first rack 305 and drives the moving frame 301 to move linearly on the lifting plate 103. The reciprocating horizontal movement and the linear movement are coordinated with each other to perform reciprocating polishing, which can make the polishing more delicate and full. After the polishing of the upper surface of the aircraft cabin floor is completed, the lifting plate 103 is driven to move up and down through the lifting mechanism 2. After the polishing mechanism 5 is separated from the aircraft cabin floor, the elastic force of the spring 516 pushes the end of the movable pin 517 to move downward and contact the bottom end of the inner wall of the discharge frame 514 to cover the liquid outlet groove so that the polishing liquid cannot be discharged. The aircraft cabin floor is manually turned over, and the lower surface of the aircraft cabin floor is polished using the same steps.
