Description

Technical Field

[0001] This utility model relates to the field of drone parts manufacturing technology, and in particular to a processing and polishing device. Background Technology

[0002] Drones contain numerous components. To improve the assembly precision of these components, they undergo grinding before use. After grinding, surface treatment is applied to enhance their corrosion resistance and extend their lifespan. Due to the large number of components, grinding is typically performed using a grinding device. Traditional grinding devices generally consist of a motor and a grinding wheel or disc. The disc usually has a rough surface. When the motor drives the grinding wheel or disc to rotate, it rubs against the surface of the drone's components, thus creating surface grinding.

[0003] Patent document CN214186440U discloses a grinding device for drone accessories. The device includes a base plate, with a motor bolted to the top of the base plate. One end of the motor's output shaft is connected to a rotating shaft via a flange. The end of the rotating shaft away from the motor is threaded to a fastening ring. The inner wall of the fastening ring has a conical groove containing four jaws. A propeller shaft is positioned between the four jaws. Two fixing plates are bolted to the top outer wall of the base plate, and two optical axis slide rails are bolted between the two fixing plates. Sliding bodies are slidably connected to the outer walls of the two optical axis slide rails, and a grinding stone is mounted on the top of each sliding body. This invention utilizes the jaws and T-slots to clamp drone propeller shafts of different diameters. The jaws, combined with the T-slots, allow the grinding stone to adjust its distance from the propeller shaft, thus enabling the grinding stone to slide along the optical axis slide rails and grind propeller shafts of different diameters.

[0004] When using the above technology, the following technical problems were found in the existing technology: when using the existing grinding equipment, it is not convenient to flip the parts when grinding the upper and lower end faces of the parts. Therefore, a processing and grinding device is designed to provide another technical solution to the above technical problems. Utility Model Content

[0005] Therefore, it is necessary to provide a processing and polishing device to address the above-mentioned technical problems, in order to solve the technical problem that existing polishing equipment is not convenient for flipping the parts when polishing the upper and lower end faces of the parts.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A processing and polishing device includes a worktable and a polishing mechanism. The polishing mechanism is located on the top of one side of the worktable. Both ends of the top of the worktable are provided with translation frames. The worktable is equipped with a translation mechanism for driving the two translation frames to move in opposite directions. Each translation frame is provided with a clamping mechanism for positioning parts. The translation mechanism includes a dual-axis drive motor, a threaded rod, and a translation plate. The translation plates are slidably connected to the interior of both ends of the worktable. The top of the translation plates is fixed to the translation frames. The dual-axis drive motor is fixed to the bottom of the interior of the worktable. The output end of the dual-axis drive motor is connected to a threaded rod.

A rotating disk is fixed to the bottom outer side of the central column, and clamping blocks are evenly distributed and fixed to the outer side of the rotating disk.

[0009] In a preferred embodiment of the processing and polishing device provided by this utility model, the thickness of the ends of the multiple clamping blocks away from the rotating disk is not the same.

[0010] In a preferred embodiment of the processing and polishing device provided by this utility model, one end of the translation frame is fixed with a rotary drive motor.

[0011] In a preferred embodiment of the processing and polishing device provided by this utility model, a push rod motor is fixed inside the worktable and located between two rotating frames. The push rod of the push rod motor extends out of the top of the worktable, and a support sleeve is threadedly connected to the outer side of the top of the push rod of the push rod motor.

[0012] In a preferred embodiment of the processing and polishing device provided by this utility model, an anti-rotation mechanism for limiting the rotation angle of the rotating disk is installed on the rotating frame.

The anti-rotation column is slidably connected inside the rotating frame and is slidably connected to the rotating disk. The lifting plate is fixed to the top of the anti-rotation column. Tension springs are fixed between the bottom of both sides of the lifting plate and the rotating frame. An intermittent drive motor is fixed to the top of the rotating frame and at one end of the anti-rotation column. The output end of the intermittent drive motor is connected to the adjusting rod.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0028] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0029] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0030] Reference Figures 1-5 A processing and polishing device includes a worktable 1 and a polishing mechanism 2. The polishing mechanism 2 is located on the top of one side of the worktable 1. Both ends of the top of the worktable 1 are provided with a translation frame 3, and the two translation frames 3 are arranged symmetrically. The worktable 1 is equipped with a translation mechanism for driving the two translation frames 3 to move in opposite directions. The translation mechanism drives the translation frames 3 to move and adjust the position of the clamping mechanism. Each translation frame 3 is provided with a clamping mechanism for positioning the parts. The parts are fixed by the clamping mechanism.

[0031] In this embodiment, the grinding mechanism 2 is existing technology, which can be composed of a lateral adjustment component, a longitudinal adjustment component, a height adjustment component, and a grinding component. It can refer to the relevant structure in a grinding device for processing UAV parts published in CN222244063U. The lateral adjustment component and the longitudinal adjustment component can both be a linear motor rotary drive motor 10 and related structures to realize lateral and longitudinal translation adjustment. The height adjustment component can be a second electric push rod rotating frame 11, and the grinding component is a grinding head adjustment drive motor 13. All of them are used to achieve the effect of grinding the top of the parts.

[0032] The translation mechanism includes a dual-axis drive motor 6, a threaded rod 7, and a translation plate 8. The translation plates 8 are slidably connected to the interior of both ends of the worktable 1. The top of the translation plate 8 is fixed to the translation frame 3, so that the translation of the translation plate 8 in the worktable 1 drives the corresponding translation frame 3 to translate. The dual-axis drive motor 6 is fixed to the bottom of the worktable 1. The output end of the dual-axis drive motor 6 is connected to the threaded rod 7. The outer side of the threaded rod 7 is threadedly connected to the translation plate 8, so that the rotation of the threaded rod 7 drives the translation plate 8 to translate and adjust inside the worktable 1.

[0033] The clamping mechanism includes a rotating shaft 9, a rotating frame 11, a rotating disk 12, an adjusting drive motor 13, a central column 14, and a clamping block 15. The top of each of the two translation frames 3 is provided with a rotating frame 11 at one adjacent end, and the rotating frame 11 is U-shaped. The rotating shaft 9 is rotatably connected inside the translation frame 3, and the rotating shaft 9 is fixed to the rotating frame 11, so that the rotation of the rotating shaft 9 inside the translation frame 3 drives the rotating frame 11 to rotate at an angle. The central column 14 is rotatably connected to the inner side of the rotating frame 11. The adjusting drive motor 13 is fixed to the top of the rotating frame 11, and the output end of the adjusting drive motor 13 is connected to the central column 14, so that the operation of the adjusting drive motor 13 drives the central column 14 to rotate.

[0034] A rotating disk 12 is fixed to the bottom of the outer side of the central column 14, so that the rotation of the central column 14 drives the rotating disk 12 to rotate synchronously. Clamping blocks 15 are evenly distributed and fixed on the outer side of the rotating disk 12, so that the rotation of the rotating disk 12 drives the clamping blocks 15 to rotate on the inner side of the rotating frame 11. The thickness of the ends of the multiple clamping blocks 15 away from the rotating disk 12 is different, so that the thickness of the end of the clamping block 15 on the outer side of the same rotating disk 12 is different. Thus, the clamping blocks 15 with different end thicknesses can be used to clamp drone parts of different thicknesses during grinding.

[0035] Preferably, the end of the clamping block 15 away from the rotating disk 12 is provided with anti-slip texture, which can reduce the drop of the accessory between the two clamping blocks 15 to a greater extent. Alternatively, the clamping blocks 15 can fix the two ends of the accessory through the support of the support sleeve 5.

[0036] In this embodiment, there are four clamping blocks 15. In other embodiments, the number can be changed as needed. In other embodiments, the clamping blocks 15 and the rotating disk 12 can be fixed by bolts or welding, and can be adjusted according to the layout.

[0037] Preferably, one end of one of the translation frames 3 is fixed with a rotary drive motor 10, and the output end of the rotary drive motor 10 is connected to the rotating shaft 9, so that the operation of the rotary drive motor 10 drives the rotating shaft 9 to drive the rotating frame 11 to rotate by an angle. In other embodiments, each translation frame 3 is fixed with a rotary drive motor 10 for driving the rotating shaft 9 to rotate. The two rotary drive motors 10 can be electrically operated to rotate by an externally controlled switch.

[0038] Inside the worktable 1, between the two rotating frames 11, is a push rod motor 4. The bottom end of the push rod motor 4 is fixed to the top of the dual-axis drive motor 6 inside the worktable 1. The push rod of the push rod motor 4 extends out of the top of the worktable 1, so that the working adjustment push rod of the push rod motor 4 is at the top of the worktable 1. The outer side of the push rod top is threaded with a support sleeve 5, so that the support sleeve 5 can be replaced according to the width of the grinding parts. The top of the support sleeve 5 supports the bottom center of the grinding parts.

[0039] The rotating frame 11 is equipped with an anti-rotation mechanism to limit the rotation angle of the rotating disk 12. The anti-rotation mechanism includes a lifting plate 17, an anti-rotation column 18, a tension spring 19, an intermittent drive motor 20, and an adjusting rod 21. The anti-rotation column 18 is slidably connected inside the rotating frame 11. The anti-rotation column 18 is slidably connected to the rotating disk 12, so that when the bottom end of the anti-rotation column 18 is lowered and located inside the rotating disk 12, the rotating disk 12 cannot rotate. Anti-rotation holes 16 are evenly distributed inside the top of the rotating disk 12 and outside the center column 14. The number of anti-rotation holes 16 corresponds to the number of clamping blocks 15. The lifting plate 17 is slidably connected to the rotating disk 12 through the anti-rotation holes 16. When the anti-rotation column 18 disengages from the inside of one anti-rotation hole 16 and enters the inside of the next anti-rotation hole 16, the rotation of the rotating disk 12 causes the clamping block 15 to be replaced once.

[0040] A lifting plate 17 is fixed to the top of the anti-rotation column 18. Tension springs 19 are fixed between the bottom of both sides of the lifting plate 17 and the rotating frame 11. When the lifting plate 17 rises, it drives the anti-rotation column 18 to rise and stretches the tension springs 19. An intermittent drive motor 20 is fixed to the top of the rotating frame 11 and at one end of the anti-rotation column 18. An adjusting rod 21 is connected to the output end of the intermittent drive motor 20. The intermittent drive motor 20 drives the adjusting rod 21 to rotate. The lifting plate 17 is driven to rise through the contact and compression between the adjusting rod 21 and the lifting plate 17.

[0041] In this embodiment, the motor is a self-locking motor, which can drive the connected structure to rotate normally when it is powered on and working. When the motor stops working, it can prevent the connected structure from rotating through its self-locking function.

[0042] The process of using the processing and grinding device provided by this utility model is as follows: During use, the thickness of the grinding parts is adjusted as needed. At this time, the intermittent drive motor 20 is controlled to operate, causing the intermittent drive motor 20 to drive the adjusting rod 21 to rotate. The rotation of the adjusting rod 21 causes the lifting plate 17 to rise through compression. The rising of the lifting plate 17 causes the anti-rotation column 18 to rise, simultaneously stretching the tension spring 19. At this time, the rising anti-rotation column 18 disengages from the corresponding anti-rotation hole 16. Then, the adjusting drive motor 13 is controlled to operate, causing the adjusting drive motor 13 to drive the rotating disk 12 to rotate through the central column 14. The rotation of the rotating disk 12 then causes the intermittent drive motor 20 to drive the adjusting rod 21 to rotate. After the lever 21 rotates, when the adjusting lever 21 does not press against the bottom of the lifting plate 17, the lifting plate 17 rebounds and falls after being stretched by the tension spring 19, so that the bottom of the anti-rotation column 18 contacts the top of the rotating disk 12 and stops the operation of the intermittent drive motor 20. At this time, the rotation of the rotating disk 12 drives the clamping block 15 to rotate inside the rotating frame 11. After adjusting the clamping block 15 with the corresponding end thickness, the operation of the adjusting drive motor 13 is notified. At this time, the bottom end of the anti-rotation column 18 corresponds to the position of the corresponding anti-rotation hole 16. The folded anti-rotation column 18 rebounds and falls after being stretched by the tension spring 19, so that the bottom end of the anti-rotation column 18 enters the interior of the corresponding anti-rotation hole 16, thereby limiting the rotation of the rotating disk 12.

[0043] Then, the dual-axis drive motor 6 drives the threaded rod 7 to rotate, which in turn moves the threaded translation plate 8. The two translation plates 8 move closer together, which in turn moves the two translation frames 3 closer together. The grinding parts are then held by the clamping blocks 15 on the outer side of the rotating disk 12 on the two translation frames 3. At the same time, the push rod motor 4 drives the support sleeve 5 to support the bottom center of the grinding parts. Then, the grinding head on the grinding mechanism 2 grinds the top of the drone parts. After grinding, the push rod motor 4 drives the support sleeve 5 to descend. Then, the rotary drive motor 10 drives the corresponding rotating frame 11 to rotate through the rotating shaft 9, thereby flipping the grinding parts.

These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
