Description

Technical Field

[0001] This utility model relates to the field of parts polishing, and in particular to a polishing device for aerospace parts. Background Technology

[0002] An existing patent (publication number: CN222134573U) proposes a polishing device for aerospace components. By activating the drive assembly, the first gear can be driven to rotate, which in turn drives the first gear to slide against the horizontal slide block fixed at the bottom of the support block. The first gear also drives the second gear to rotate, which in turn drives the first support assembly to rotate. However, this device only uses one grinding wheel for polishing, which causes friction when the tube is close to the center of the outer side of the grinding wheel. This results in the tube being subjected to force in one direction on the side, which may cause the tube to shift and affect the polishing accuracy. Summary of the Invention

[0003] This invention addresses the aforementioned shortcomings of existing technologies by providing an aerospace component polishing device. This device utilizes three sets of polishing rollers to simultaneously polish aerospace components from three directions. During polishing, the forces acting on the aerospace components in each direction are balanced, preventing the components from shifting in any particular direction, thus reducing polishing errors and increasing polishing precision.

[0004] The objective of this utility model is achieved through the following technical solution: A polishing device for aerospace components includes a main support base, a rotary drive motor, a polishing roller, aerospace components, a displacement drive ring, and a first locking block. The main support base has a first support platform on one side and a second support platform on the other side. A first support block is located in the center of the first support platform, and a driven block connecting platform is located on the side of the first support block. Three sets of driven block connecting platforms are evenly arranged around the first support block. Each driven block connecting platform has a driven block connecting groove inside, which is adapted to a driven slider. The driven slider is connected to the driven block connecting groove and slides within the groove. The first support block has... There is a No. 1 locking block connecting groove. A No. 1 locking block is provided on the side of the No. 1 support block facing the middle of the main support base. A No. 1 locking block connecting post is provided on the side of the No. 1 locking block facing the No. 1 support block. The No. 1 locking block connecting post is rotatably connected to the No. 1 locking block connecting groove. A rotating motor mounting platform is provided on the side of the No. 1 support block away from the No. 1 locking block. A rotating drive motor is inserted into the rotating motor mounting platform and fixed. The rotating drive motor has a transmission shaft fixedly connected to the No. 1 locking block. A polishing roller is provided on the side of the driven slider near the middle of the main support base. A driven block connecting post is provided on the side of the polishing roller facing the driven slider. The driven slider is rotatably connected to the driven block connecting post.

[0005] The second support platform has a second support block in the middle, and a drive rod connecting platform on the side of the second support block. Three sets of drive rod connecting platforms are evenly arranged around the second support block. The end of the drive rod connecting platform has a drive rod connecting groove. A displacement drive ring is provided on the side of the second support block away from the middle of the main support seat. A displacement drive slide is provided on the side of the displacement drive ring. Three sets of displacement drive slides are evenly arranged around the displacement drive ring. The displacement drive slide is adapted to the drive rod connecting groove and is connected to the drive rod connecting groove. The displacement drive slide slides inside the drive rod connecting groove. The end of the displacement drive slide has a displacement drive block. The side of the displacement drive block facing the middle of the displacement drive ring has an outer connecting rod mounting platform. The side of the polishing roller away from the driven block connecting column has a displacement block mounting shaft.

[0006] Beneficial effects: 1. When polishing aerospace parts, the present invention uses three sets of polishing rollers to polish the aerospace parts simultaneously in three directions. During the polishing process, the forces on the aerospace parts in each direction are balanced, so that the aerospace parts will not deviate in one direction, reducing the error of the polishing process and increasing the accuracy of the polishing process.

[0007] 2. The displacement drive block and displacement driven block of this utility model are connected by two sets of parallel displacement linkages. The distance between each displacement driven block can be controlled by changing the position of the displacement drive block. This allows the device to polish aerospace parts of different radii. At the same time, all polishing rollers move synchronously, and the adjustment process is efficient and convenient.

[0008] 3. The telescopic column of this utility model slides inside the telescopic column connecting groove, thereby controlling the distance between the second and first blocks by changing the extension length of the telescopic rod of the inner telescopic cylinder. This allows the device to polish aerospace parts of different lengths, further increasing the adaptability of the device.

[0009] 4. The polishing roller array of this utility model has an inverted triangular structure, which allows the two polishing rollers at the top to have a larger space reserved for the placement of aerospace parts when they are far apart from each other. This makes it easier to put or take out aerospace parts from the top, increasing the convenience of placing or removing aerospace parts. Attached Figure Description

When the polishing rollers 5 are far apart from each other, the two polishing rollers 5 at the top provide a larger space for the placement of aerospace parts 6, which facilitates the placement or removal of aerospace parts 6 from the top, increasing the convenience of placing or removing aerospace parts 6. The side of the polishing roller 5 facing the driven slider 18 has a driven block connecting post 19, which is rotatably connected to the driven slider 18.
