[0015] Beneficial effects of the present invention: The present invention realizes that the clamp can flip ninety degrees each time when clamping the component through the design of the driven rotating component, the transmission rotating component and the clamping component, so that the component to be processed can be fixed at a desired angle, and the component can be processed on multiple sides, which improves convenience and avoids the problem that the mechanical processing clamp cannot be flipped after fixing the drone component, which will cause inconvenience in performing process operations on the front and back sides of the drone component.

[0016] The present invention can easily perform a flipping operation when clamping a workpiece, and is particularly suitable for UAV parts that require multi-faceted processing. The transmission structure of the worm and the worm gear can achieve precise angle control, which not only improves processing efficiency but also reduces the complexity of operation.

[0017] The present invention is driven by a motor, and the clamp can be turned over 90 degrees each time, which simplifies multi-faceted processing operations and realizes multi-angle turning and clamping.

[0018] The present invention realizes accurate adjustment of the workpiece angle through the combination of the worm, the worm wheel and the transmission plate, improves processing flexibility and realizes precise mechanical control.

[0019] The present invention adopts a Z-shaped clamping plate and a screw drive design to make the clamping process more stable, can adapt to drone components of different sizes, and realizes the innovation of the clamp structure.

[0020] The present invention adopts the design of the adjustment mechanism so that the distance between the two push plates can be adjusted according to the drone parts of different sizes. That is, the output motor drives the worm to rotate, the rotation of the worm drives the rotating gear to rotate through the worm wheel, and the rotation of the rotating gear drives the push-pull racks on both sides to move, thereby achieving the effect of adjusting the distance between the two push plates.

[0021] The present invention adopts the design of the transmission rotating assembly, the flip motor is energized, and the transmission disk is driven to rotate through the rotating shaft. The rotation of the transmission disk drives the driven rotating assembly to perform linkage action through the push rod and the limit groove.

[0022] The present invention adopts the design of the driven rotating component. When the transmission disk rotates, the pushing rod on it will rotate into the cross-shaped groove on the driven wheel base and squeeze the inner wall of the cross-shaped groove to realize the work of pushing the driven wheel base to rotate. The rotation of the driven wheel base will drive the clamping assembly and the parts to rotate through the axial rod.

[0023] The present invention adopts the design of the clamping assembly. When the clamping motor is energized, it drives the transmission bevel gear at the end to rotate. The meshing of the transmission bevel gear drives the bevel gear to rotate and then drives the screw rod to rotate. When the screw rod rotates, it drives the two Z-shaped clamping plates to move symmetrically up and down to clamp the workpiece.

[0024] Through the design of the protection mechanism of the present invention, when the pushing plate moves, it will drive the dustproof bracket fixed to the end thereof to move, and the dustproof bracket will gradually move out of the accommodating groove on the dustproof main frame while moving, thereby realizing the extension of the dustproof bracket, and then the adjusting mechanism is protected and shielded by the dustproof main frame and the dustproof bracket, and the waste debris generated during processing will fall into the collecting groove on the dustproof main frame and the collecting frame on the dustproof bracket for waste collection; after the workpiece is completed, the waste that falls into the collecting frame will be scraped off by the inclined groove at the opening of the collecting groove when the dustproof bracket receives it, so that the dust in the collecting frame will be received in the collecting groove for convenient unified recycling and treatment.

[0025] Through the design of the dust suction component of the present invention, the waste debris dropped on the dust proof bracket will be sucked by a plurality of dust suction ports, and the fan suctions air to generate negative pressure to absorb the waste debris through the dust suction ports, and the waste debris will be transported to the dust collecting chamber through the air supply hose and the turntable, and when the negative pressure airflow enters the dust collecting chamber, the negative pressure airflow will flush open the cover plate, and when the fan is not started, there is no negative pressure airflow, and the cover plate will again block and protect the connection between the dust collecting chamber and the fan.

[0026] Through the design of the collecting component, the negative pressure airflow entering the dust collecting chamber carries the waste debris and passes through several filter screens from top to bottom for filtering treatment. After a long period of filtration, a large amount of waste debris will be retained on the filter screen. At this time, the driving motor is started, and the driving motor drives the outer gear ring to rotate through the active gear, and the outer gear ring drives the rotating cylinder to rotate with the fixed rod as the center. When the rotating cylinder rotates, it will drive several rotating shafts to rotate. The rotation of the rotating shaft will drive the side bevel gears at its end to rotate horizontally. While the side bevel gears rotate horizontally, they will move along the fixed bevel gears, thereby realizing the vertical rotation of the rotating shaft, so that the dust collection cylinder and the friction protrusions that rotate horizontally and vertically will scrape and clean the filter screen. Because the dust collection cylinder and the friction protrusions are respectively made of rubber strip adhesive blocks and dust collection sponges, the waste debris on the filter screen can be adhered and adsorbed.

[0042] The operation process of the driven rotating assembly is as follows: while the transmission disk 13 rotates, the push rod 11 thereon will rotate into the cross-shaped groove 9 on the driven wheel base 8 and squeeze the inner wall of the cross-shaped groove 9 to realize the work of pushing the driven wheel base 8 to rotate; the rotation of the driven wheel base 8 will drive the clamping assembly and parts to rotate through the axial rod 22; and, after the push rod 11 on the transmission disk 13 is disengaged from the cross-shaped groove 9 on the driven wheel base 8, the limiting groove 14 on the transmission disk 13 will match with the columnar protrusion 10 on the driven wheel base 8 to play the role of limiting the driven wheel base 8, thereby achieving the purpose of stable 90-degree flipping.

[0043] The operation process of the clamping assembly is as follows: when the clamping motor 16 is energized, it drives the transmission bevel gear 19 at the end to rotate, and the transmission bevel gear 19 engages with the driven bevel gear 21 to rotate, thereby driving the bidirectional threaded screw 20 to rotate. When the bidirectional threaded screw 20 rotates, it drives the two Z-shaped clamping plates 15 to move symmetrically up and down to clamp the workpiece.

[0044] The operation process of the protection mechanism is as follows: when the push plate 2 moves, it will drive the dustproof bracket 32 ​​fixed to the end thereof to move; while the dustproof bracket 32 ​​moves, it will gradually move out of the accommodating groove 29 on the dustproof main frame 26, thereby realizing the extension of the dustproof bracket 32, and then the adjustment mechanism is protected and shielded by the dustproof main frame 26 and the dustproof bracket 32; the waste debris generated during processing will fall into the collecting groove 27 on the dustproof main frame 26 and the collecting frame 31 on the dustproof bracket 32 ​​for waste collection; after the workpiece is completed, the waste that falls into the collecting frame 31 will be scraped off by the inclined groove 28 at the opening of the collecting groove 27 when the dustproof bracket 32 ​​is stored, so that the dust in the collecting frame 31 will be stored in the collecting groove 27 for unified recycling and treatment.

[0045] The operation process of the dust suction component is as follows: the waste debris dropped on the dustproof bracket 32 ​​will be sucked by a number of dust suction ports 34; the fan 37 generates negative pressure by suction to absorb the waste debris through the dust suction ports 34; the waste debris will be transported to the dust collecting chamber 35 through the air supply hose 39 and the transfer plate 38; when the negative pressure airflow enters the dust collecting chamber 35, the negative pressure airflow will open the cover 40; when the fan 37 is not started, there is no negative pressure airflow, and the cover 40 will again block and protect the connection between the dust collecting chamber 35 and the fan 37.

[0046] The operation process of the collection component is as follows: the negative pressure airflow entering the dust collecting chamber 35 carries the waste debris and passes through a plurality of filter screens 33 from top to bottom for filtering. After a long period of filtration, a large amount of waste debris will be trapped on the filter screens 33. At this time, the drive motor 42 is started, and the drive motor 42 drives the outer gear ring 45 to rotate through the driving gear 43. The outer gear ring 45 drives the rotating cylinder 44 to rotate with the fixed rod 47 as the center. When the rotating cylinder 44 rotates, it will drive a plurality of rotating shafts 49 to rotate. The rotation of the rotating shaft 49 will drive the side bevel gear 52 at its end to rotate horizontally. While the side bevel gear 52 rotates horizontally, it will move along the fixed bevel gear 48, thereby realizing the vertical rotation of the rotating shaft 49, so that the dust collection tube 50 and the friction protrusion 51 that rotate horizontally and vertically will scrape and clean the filter 33. Because the dust collection tube 50 and the friction protrusion 51 are respectively made of a rubber strip adhesive block and a dust collection sponge, they can adhere to and adsorb waste debris on the filter 33.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
