DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0023] The present application provides an aviation component grinding and polishing device, which is mainly used to solve the problem that the diameters of tubular components (casings) are different in the prior art, which makes the aviation component grinding and polishing device have certain limitations and is only applicable to components of specific specifications, which not only increases the difficulty and cost in component production, but also lacks flexibility and versatility. The following technical solutions are provided. Figure 1-Figure 4 Make a detailed description:

[0024] An aviation parts grinding and polishing device, comprising:

[0025] A base plate 1, a mounting frame 2 is fixedly provided on one side of the top thereof, and a molded plate 3 is fixedly provided on the other side;

[0026] The fixing block 4 and the tubular component 5 are fixed between the bottom sides of the shaped plate 3, and the top of the fixing block 4 is evenly spaced with V-shaped grooves 401, and the tubular component 5 is embedded in the V-shaped grooves 401;

[0027] The polishing mechanism 6 is used to grind and polish the inner wall of the tubular component 5. The polishing inner diameter of the polishing mechanism 6 is adjustable. The polishing mechanism 6 includes a movable rod 601 that is rotatably connected to the surface of the mounting frame 2 at equal intervals. One end of the movable rod 601 is connected to a hollow plate 602. The tubular component 5 is sleeved on the outside of the hollow plate 602. Slide plates 603 are arranged on both sides of the hollow plate 602 to slide up and down alternately. A polishing sheet 604 is fixed on one side of the slide plate 603 located outside the hollow plate 602. A spring 605 is connected between one side of the slide plate 603 located inside the hollow plate 602 and the inner wall of the hollow plate 602. A driving member 8 for driving the movable rod 601 to rotate is arranged in the mounting frame 2;

[0028] The clamping mechanism 7 is arranged on the upper side inside the U-shaped plate 3 and is used for clamping and fixing the tubular component 5. The clamping mechanism 7 includes a rotating rod 701 rotatably connected between the inner side walls of the U-shaped plate 3. Threads with opposite spiral directions are formed on both sides of the rotating rod 701, and mounting blocks 702 are symmetrically connected by threads. The mounting blocks 702 are slidably connected to the inner top wall of the U-shaped plate 3. A connecting plate 703 is hinged to the bottom side of the mounting block 702. A lifting plate 704 is slidably arranged on the inner top wall of the U-shaped plate 3 below the rotating rod 701. One end of the connecting plate 703 away from the mounting block 702 is hinged to the top of the lifting plate 704. A clamping block 705 is fixedly arranged at the bottom of the lifting plate 704 corresponding to the position of the V-shaped card slot 401.

[0029] It should be noted that the inner diameter of the tubular component 5 in this device should be greater than the width of the hollow plate 602 to ensure that the polishing sheet 604 will not be stuck under the action of the spring 605.

[0030] The specific implementation process and principle description of this aircraft component grinding and polishing device:

[0031] First step, place the tubular component 5 to be processed in the V-shaped card slot 401 of the fixed block 4 to ensure its stability.

[0032] Second step, by rotating the rotating rod 701, the position of the mounting block 702 can be adjusted, changing the angle between the connecting plate 703 and the lifting plate 704, thereby controlling the lifting of the lifting plate 704, and then driving the clamping block 705 to move downward, so as to realize the clamping and fixing of the tubular component 5.

[0033] Third step, start the driving part 8 to make the movable rod 601 rotate. When the movable rod 601 rotates, the sliding plate 603 moves outward to the outside of the hollow plate 602 under the action of the spring 605, so that the polishing sheet 604 abuts against the inner wall of the tubular component 5. During the rotation of the hollow plate 602 following the movable rod 601, the polishing sheet 604 can polish the inner wall of the tubular component 5. Through the cooperation of the sliding plate 603 and the spring 605, the polishing sheet 604 can abut against the tubular components 5 with different inner diameters, so as to realize the grinding and polishing of tubular components 5 with different specifications.

[0034] Fourth step, after the grinding and polishing are completed, turn off the driving part 8, loosen the clamping mechanism 7, and take out the processed tubular component 5.

[0035] This aircraft component grinding and polishing device can flexibly clamp and fix tubular components 5 with different specifications by setting the clamping mechanism 7, and polish the inner wall thereof. The polishing inner diameter of the polishing mechanism 6 is adjustable to meet the requirements of different tubular components 5. This device has high flexibility and versatility, can meet diversified and personalized processing needs, reduces the production difficulty and cost, and improves the assembly quality of the parts.

[0036] As Figure 1 shown, in some embodiments, the driving member 8 includes a worm gear 801 fixedly arranged at the end of the movable rod 601. A mounting rod 802 is rotatably connected between the inner side walls of the mounting frame 2. A worm 803 is equidistantly arranged on the surface of the mounting rod 802. The worm 803 meshes with the worm gear 801. An electric motor 804 is mounted on the outer wall of the mounting frame 2. The output shaft of the electric motor 804 is connected to the mounting rod 802. More specifically, by the rotation of the output shaft of the electric motor 804, the mounting rod 802 is driven to rotate. Since the worm 803 meshes with the worm gear 801 and the worm gear 801 is fixed at the end of the movable rod 601, the rotation of the mounting rod 802 will drive the movable rod 601 to rotate. In this way, the polishing mechanism 6 can polish the inner wall of the tubular part 5.

[0037] As Figure 3 shown, in some embodiments, both ends of the rotating rod 701 penetrate through the U-shaped plate 3 and are connected with knobs. More specifically, both ends of the rotating rod 701 penetrate through the U-shaped plate 3 and are connected with knobs. Its main function is to facilitate the operator to adjust the clamping mechanism 7. By rotating the knobs, the rotation of the rotating rod 701 can be controlled, thereby driving the movement of the mounting block 702 and realizing the position control of the lifting plate 704.

[0038] As Figure 3 shown, in some embodiments, a V-shaped notch is formed in the middle of the bottom of the clamping block 705. More specifically, the design of forming a V-shaped notch in the middle of the bottom of the clamping block 705 is mainly used to facilitate the fixation of tubular parts 5 of different specifications. The V-shaped notch can adapt to the size of the tubular part 5, limit it in the correct position, and prevent it from shifting during the polishing process. At the same time, this design also improves the stability and firmness of the clamping mechanism 7, ensuring the safety and effect of the processing process. By reasonably adjusting the clamping mechanism 7, the V-shaped notch of the clamping block 705 can be closely adapted to tubular parts 5 of different specifications, thereby realizing the flexibility and versatility of the aviation part polishing and grinding device.

[0039] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the broadest scope consistent with the principles and novel features disclosed herein.
