[0002] With the continuous development of drone technology, drones are being used more and more widely in various fields. In the manufacturing process of drones, mechanical processing is an indispensable link. During the mechanical processing, fixtures are needed to fix the mechanical parts of the drone, so as to facilitate cutting and welding of the mechanical parts. General fixtures include a base plate, a fixed plate, a cylinder and a pressure plate. The pressure plate is fixedly connected to the output end of the cylinder. When in use, the staff will place the mechanical parts on the base plate and fit one side of it with the fixed plate, and then start the cylinder to push the pressure plate. The pressure plate will squeeze the mechanical parts from the other side of the mechanical parts, and use the pressure plate and the fixed plate to squeeze and fix the mechanical parts, so as to facilitate subsequent cutting, welding and other work.

Since the existing tooling and fixtures cannot clean these debris, these debris may affect the cutting tools, thereby affecting the processing accuracy and surface quality of the mechanical parts. In severe cases, it may also cause damage to the mechanical parts and increase manufacturing costs. Utility Model Content

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] like Figures 1 to 5 As shown, a fixture for machining unmanned aerial vehicles comprises a fixture body 1, a connecting plate 2 is fixedly connected to one side of the fixture body 1, a suction pipe 3 is fixedly connected to the surface of the connecting plate 2, a side of the suction pipe 3 away from the fixture body 1 is fixedly connected to an exhaust pipe 4, an air inlet chamber 19 is defined in the suction pipe 3, an exhaust chamber 5 is defined in the exhaust pipe 4, a motor 6 is connected to the exhaust chamber 5, a plurality of equidistantly arranged fixing plates 7 are fixedly connected to the outer wall of the motor 6, a side of the fixing plate 7 away from the motor 6 is fixedly connected to the inner wall of the exhaust chamber 5, a rotating shaft 8 is fixedly connected to the output end of the motor 6, and a fan 9 is fixedly connected to the outer wall of the rotating shaft 8.

[0024] like Figure 1 As shown, the tooling fixture for UAV machining in the utility model is similar to the existing tooling fixture structure, such as a UAV pneumatic fixture disclosed in the patent with publication number CN206643652U. The main improvement of the utility model is that it enables the debris generated during the cutting process to be cleaned, such as Figures 1 to 5As shown, when a tooling fixture for mechanical processing of an unmanned aerial vehicle in the utility model is in use, when cutting mechanical parts, the motor 6 will drive the rotating shaft 8 and the fan 9 to rotate. The rotation of the fan 9 will drive the air flow, and the air in the suction pipe 3 will be drawn into the exhaust pipe 4 and discharged. At this time, a huge negative pressure will be generated between the air inlet chamber 19 and the outside world. Under the action of the negative pressure, the outside air will be drawn into the suction pipe 3, and the cutting chips will be driven to move by the outside air, thereby sucking the cutting chips into the air inlet chamber 19, thereby preventing the chips from staying on the surface of the mechanical parts and affecting the cutting work of the mechanical parts.

[0025] By arranging a suction pipe 3 on the connecting plate 2 and a fan 9 in the exhaust pipe 4, and utilizing the cooperation between the fan 9 and the suction pipe 3, it is possible to clean up the debris generated during the cutting process of the mechanical parts, thereby preventing the debris from affecting the cutting work of the mechanical parts, improving the processing accuracy and surface quality of the mechanical parts, reducing the risk of damage to the mechanical parts, and reducing the manufacturing cost.

[0026] like Figure 1 and Figure 2 As shown, the air suction pipe 3 is fixedly connected to a side close to the fixture body 1 with an air expansion port 10 , and the cross-sectional area of ​​the air expansion port 10 is larger as it is close to the fixture body 1 .

[0027] Specifically, the air expansion port 10 can increase the air suction area of ​​the air suction pipe 3 , improve the air suction effect of the air suction pipe 3 , and improve the cleaning ability of the air suction pipe 3 .

[0028] like Figure 2 and Figure 4 As shown, a storage box 11 is slidably connected in the air inlet cavity 19 , a side wall of the air suction pipe 3 is penetrated on one side of the storage box 11 and a cover plate 12 is fixedly connected thereto, and a plurality of ventilation holes 13 are opened on one side of the storage box 11 close to the fan 9 .

[0029] Specifically, after the debris is sucked into the air inlet chamber 19, the air will be discharged through the vents 13, and the debris will be blocked by the storage box 11 and accumulated in the storage box 11. When there is a lot of debris in the storage box 11, the staff can pull the cover 12 to slide the storage box 11 out of the air inlet chamber 19, and then pour out the debris and reinsert the storage box 11 for cutting. This arrangement makes it easy for the staff to collect the debris, and at the same time prevents the debris from entering the exhaust chamber 5 and damaging the fan 9 and the motor 6.

[0030] like Figure 2 and Figure 4 As shown, a magnetic attraction ring 15 is fixedly connected to one side of the air suction pipe 3 and the inner side of the cover plate 12, and the two magnetic attraction rings 15 match in shape and position.

[0031] Specifically, by using two magnetic circles 15 , it is possible to ensure that the cover plate 12 and the air suction pipe 3 are fixed together, thereby improving the stability of the storage box 11 .

[0032] like Figure 2 As shown, a moving rod 14 is fixedly connected to the middle of one side of the cover plate 12 away from the magnetic attraction ring 15 .

[0033] Specifically, the moving rod 14 can facilitate the staff to pull the cover plate 12, so as to facilitate the staff to separate the two magnetic circles 15, thereby improving the use experience of the staff.

[0034] like Figure 1 and Figure 5 As shown, the side of the exhaust duct 4 away from the fan 9 is fixedly connected to an air collecting duct 16, one end of the air collecting duct 16 is fixedly connected to two universal tubes 17, the universal tubes 17 are bent to the side of the fixture body 1 away from the air collecting duct 16, one end of the universal tube 17 is fixedly connected to a nozzle 18, and the nozzle 18 faces the surface of the fixture body 1.

[0035] Specifically, the fan 9 will discharge the air drawn out from the suction pipe 3 into the air collecting pipe 16, and then pass through the universal tube 17 and be sprayed to the surface of the mechanical parts by the nozzle 18. The nozzle 18 sprays the air in the direction of the suction pipe 3. The nozzle 18 can blow the debris to the suction pipe 3, so that the suction pipe 3 can absorb and clean the debris. Through this arrangement, the cleaning effect of the debris on the surface of the mechanical parts can be improved, and the utilization rate of the fan 9 can be improved.

[0036] like Figure 1 and Figure 5 As shown, the air collecting pipe 16 is conical, and the diameter of the side away from the exhaust pipe 4 is smaller.

[0037] Specifically, the conical configuration of the air collecting pipe 16 can facilitate pressurization of the air, so that the air ejected through the nozzle 18 has a higher pressure and a higher speed, thereby being able to better blow away the debris.

[0038] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
