Description

Technical Field

[0001] The utility model belongs to the technical field of welding auxiliary tooling for UAV fuselages, and particularly relates to a welding auxiliary tooling for UAV fuselages. Background Technique

[0002] A remotely controlled UAV is an unmanned aerial vehicle remotely controlled by a remote controller. It is small in size and is used in fields such as aerial photography, agriculture, plant protection, micro selfies, express delivery, disaster relief, observing wild animals, monitoring infectious diseases, mapping, news reporting, power line inspection, disaster relief, film shooting, creating romance, etc.

[0003] During the welding process of the UAV fuselage, a large amount of harmful gases will be generated. These harmful gases generated by welding have a great impact on the human body. The existing welding auxiliary tooling cannot handle these harmful gases, which will affect the health of the staff. Moreover, some welding slag will be generated during welding, and the existing welding auxiliary tooling is not convenient for cleaning the welding slag, making it more inconvenient to use. In view of this, we propose a welding auxiliary tooling for UAV fuselages. Content of the Utility Model

[0004] The purpose of the utility model is to provide a welding auxiliary tooling for UAV fuselages to solve the problems put forward in the above background technique.

[0005] In view of this, the utility model provides a welding auxiliary tooling for UAV fuselages, including:

[0006] A base, on the top of which a protective cover is fixedly installed. On the top of the protective cover, a glass plate is fixedly installed. Two round holes are opened on the front side of the protective cover, and elastic bands are fixedly installed in both of the two round holes. A sealing door is rotatably installed on the left side of the protective cover;

[0007] A limiting component, which is located in the base and is used for limiting the sealing door;

[0008] A fixed pipe, which is fixedly installed on the rear side of the protective cover. One end of the fixed pipe is fixedly installed with an exhaust fan, and the air outlet end of the exhaust fan is fixedly installed with an installation shell, and an activated carbon filter plate is inserted and installed in the installation shell;

[0009] A fixing component, which is located on the installation shell and is used for fixing the activated carbon filter plate;

[0010] A placement table, which is fixedly installed on the inner wall of the protective cover, and a collection box is slidably installed in the protective cover and below the placement table.

[0011] In the technical solution, the limiting assembly is set to release the fixing of the sealing door, and then the sealing door can be rotated to open, and then the UAV fuselage to be welded can be placed on the top of the placement table, and then the sealing door is rotated and closed, and then the limiting assembly is set to fix the sealing door again;

[0012] Afterwards, the staff can pass both hands through the holes in the middle of the two elastic bands respectively. At this time, the elastic band will be in contact with the arm ring to ensure that the gas in the protective cover will not leak out from the round hole. Then, the welding tool in the protective cover can be used to weld the drone fuselage. Some harmful gases will be generated during welding. Start the exhaust fan, which will extract the air in the protective cover. At this time, the outside air will enter the protective cover through the dustproof net in the air inlet. Then, the exhaust fan will draw the air and harmful gases into the fixed pipe, and then transport the air and harmful gases in the fixed pipe to the installation shell. Then, the activated carbon filter plate will adsorb and filter the harmful gases. Then, the air will be discharged to the outside from the air outlet of the installation shell. When the activated carbon filter plate needs to be replaced, the fixed component is used to release the fixation of the activated carbon filter plate, and then the activated carbon filter plate can be pulled out of the installation shell.

[0013] During the welding process, some welding slag will fall on the top of the placement table. The staff can push it into the collection box for collection, which is convenient for unified cleaning.

[0014] In the above technical solution, further, the limit assembly includes:

[0015] A slide groove is opened in the base and located at the bottom of the sealed door. A limit block is slidably installed in the slide groove. One end of the limit block passes through the slide groove and extends into the sealed door. A spring is provided in the slide groove and at the bottom of the limit block. The other end of the limit block passes through one side of the slide groove and extends to the outside.

[0016] In this technical solution, the staff first presses the limit block downward. The downward displacement of the limit block will squeeze the spring to contract, so that one end of the limit block will be completely pulled out of the sealing door. At this time, the sealing door will be released and then it can be rotated to open. Then, the drone body to be welded can be placed on the top of the placement table, and then the sealing door is rotated and closed. Subsequently, under the action of the spring rebound force, the spring will push the limit block upward, so that one end of the limit block will be inserted into the sealing door, thereby fixing the sealing door again.

[0017] In the above technical solution, further, one end of the limit block is plugged into the sealing door, and the two ends of the spring are tightly welded to the bottom of the limit block and the inner wall of the slide groove respectively.

[0018] In this technical solution, ensure that one end of the limit block can be inserted into the sealing door; ensure the stable structure of the spring.

[0019] In the above technical solution, further, the fixing component includes:

[0020] A connecting plate, the connecting plate is fixedly installed on the top of the activated carbon filter plate, a sealing gasket in contact with the top of the installation shell is fixedly installed at the bottom of the connecting plate, two hand-tightening bolts are installed in the connecting plate in a threaded manner, and the lower ends of the two hand-tightening bolts both extend into the installation shell.

[0021] In this technical solution, when the activated carbon filter plate needs to be replaced, rotate the two hand-tightening bolts by hand. Under the action of the thread, the hand-tightening bolts will rotate and move upward in the installation shell and the connecting plate until the lower ends of the hand-tightening bolts move out of the installation shell. After the lower ends of the two installation shells both move out of the installation shell, the connecting plate will be released from fixation. At this time, the connecting plate can be pulled to drive the activated carbon filter plate to be withdrawn from the installation shell.

[0022] In the above technical solution, further, the lower end of the hand-tightening bolt is threadedly connected to the installation shell.

[0023] In this technical solution, under the action of the thread, when the hand-tightening bolt is rotated, the hand-tightening bolt will move downward or upward.

[0024] In the above technical solution, further, the elastic band is in a ring structure, a rubber ring is fixedly installed inside the circular hole and on one side of the elastic band, and the air inlet end of the exhaust fan is communicated with the fixed pipe.

[0025] In this technical solution, ensure that the elastic band can be in circular contact with the arm, ensure that the gas in the protective cover will not leak out from the circular hole; ensure that the air in the fixed pipe can enter the exhaust fan.

[0026] In the above technical solution, further, the fixed pipe is communicated with the inner cavity of the protective cover, an air inlet hole is opened on the right side of the protective cover, and a dust-proof net is fixedly installed in the air inlet hole.

[0027] In this technical solution, ensure that the air and harmful gases in the protective cover can enter the fixed pipe; ensure that the outside air can enter the protective cover through the dust-proof net in the air inlet hole.

[0028] The beneficial effects of the present utility model are:

[0029] 1. The auxiliary tooling for welding the fuselage of the drone, through the cooperation among the protective cover, glass plate, base, sealing door, exhaust fan, fixed pipe, installation shell, activated carbon filter plate and fixing components, ensures that the harmful gases generated during welding will not disperse to the outside, and can filter the harmful gases to avoid affecting the physical health of the staff.
